Tempest Citizenry Overall

Asskicking Leads to Leadership: Half of the reason they follow Rimuru so loyally is the fact he is one of the strongest beings in the world, with him using that power to either protect them from harm by other strong people, or defeat them and push them into submission after they tried to harm him.
Badass Army:
- Under normal circumstances, the citizens of Tempest are a peaceful mix of different monster races under the ideal of coexistence with other races as decreed by Rimuru. However, if provoked into fighting, they can mobilize into an effective and lethal fighting force because of being named monsters with all the advantages and power boosts it provides. Rimuru's top subordinates take it a step further by being strong enough to take on platoons of soldiers on their own.
- This also extends to their equipment, each soldier being outfitted with armor specifically desgined to best suit their race; The Goblin riders get light leather armor and hellmoth cloth armor for ease of mounted combat. The 300 well-trained ogres of Kurenai get samurai armor in different configurations to suit their body types. The 5000 Hobgoblins of the Green Numbers get full leather armor and helmets to compliment their balanced movement and mixed-unit tactics. The 4000 High-Orcs of the Yellow Numbers get full plate mail to maximize their defensive abilities. Finally, the 100 Dragonnewts of Hiryu get hardened and form-fitting leather armor for full flight with minimal drag. It especially helps that they have two masters of the craft ready and willing to outfit an army.
Because You Were Nice to Me: The other half of why they're loyal to Rimuru is because of how much of a Benevolent Boss he is, equally treating every citizen with kindness, no matter what race they are or even if they tried to harm him and his allies before.
Defeat Means Friendship: A decent portion of Rimuru's followers (such as the oni/kijin, the orcs, the surviving Five Fingers of Clayman, etc.) came to his side after being beaten by him or his current-at-the-time subordinates and helped to find a new purpose in life, mainly by him solving the problems that made them antagonistic in the first place and freeing them from their burdens, resulting in them owing him their lives.
Martial Pacifist: Just like their leader Rimuru, while the level of violent tendencies varies from being to being, all of them greatly desire to create a world of peace and happiness for everybody, humans included, whether due to past experience or desire to avoid disappointing Rimuru, to which they all normally go about performing diplomacy and trying their best to quell any conflicts before they get deadly. But as the Falmuth Kingdom learned the hard way after they attacked Tempest, just because they advocate peace does not mean that they are helpless pushovers that humans can easily slaughter, as once they got the chance to exact retribution for the assault, Falmuth's entire military was annihilated in less than a day.
Praetorian Guard: Both played straight and spoofed.
- The spoofed comes when Rimuru creates "The Big Four", ostensibly made up of his strongest warriors, but in reality he just came up with it because, at the time, he didn't want the big shots to enter the Tempest tournament and fight Masayuki. The group was made up of Benimaru, Shion, and Diablo, with the fourth he claimed would be crowned by whoever won the tournament. Other possible "candidates" were deemed as too busy with their own duties to be bothered with needing this "distraction". The favorite for it would have been Geld, but Gobta ended up taking it thanks to making it to the finals and (despite a self-inflicted loss) Masayuki abdicating to give him the win by default.
- Played straight by his Twelve Patrons, being the twelve acknowledged strongest warriors in Tempest under him each at the level of a True Demon Lord.
Standard Royal Court: Though not evident because of Rimuru's decree of equality among his subjects, there still exists a division of powers and responsibilities within Rimuru's subordinates. For example. Benimaru is the overall head of Tempest's military, Souei is the head of the intelligence and ninja corps, Rigurd governs over all goblins, and Geld governs over all Orcs. On the noncombatants' side, there's Vesta the chief scientific advisor and Kaijin the chief engineer and blacksmith. This greatly helps Rimuru with ruling over Tempest, as he listens to their advice and considers their input before making his final decision.
True Companions: It's not to the same extent as their loyalty to Rimuru, with the relationships between citizens being anywhere from as close as family to as strained as rivals, but every single citizen of Tempest has a strong bond with the rest of it, being able to count themselves as having the others' backs and vice-versa.
Undying Loyalty: One consistent trait among every citizen in Tempest is that they maintain complete and total loyalty to Rimuru, with them considering him the greatest being in the world and willing to do anything that he desires of them.
Vitriolic Best Buds: A good majority of the citizens have various rivalries with each other when it comes to their adoration of Rimuru and other things, such as Shuna and Shion being Clingy Jealous Girls over who loves Rimuru more, or Shion, Ranga, and Diablo competing over who does a better job as Rimuru's attendant. Despite the constant disagreements, all of them consider each other as inseparable, and will do anything to keep everybody safe, with even rival members viewing genuine harm upon one of them as call for serious retribution against the perpetrator.

Goblins

Goblins in General

Amazing Technicolor Population: They all have varying shades of green skin.
Ascended Extra: The goblin race as a whole has a massively increased role in The Slime Diaries since it focuses on the Slice of Life parts of living in Tempest rather than all the battles and political intrigue of the main series, with some like Ririna the education-and-farming-focused Goblin Lord, Gobta's group of Riders, and a Super-Deformed little goblin girl almost always around Geld all going from background characters to members of the secondary cast.
Bizarre Sexual Dimorphism: Practically the only monster race that evolve differently depending on gender: Hobgoblins generally keep their original goblin-like faces and come in a variety of shapes and sizes, while Goblinas all turn into Cute Monster Girls, looking mostly the same outside of different hairstyles.
Our Goblins Are Different: They also evolve into Hobgoblins, if male, or Goblinas, if female, once named by someone.

Goblin Leadership

Rigurd

https://static.tvtropes.org/pmwiki/pub/images/rigurudo_anime.png

Voiced by: Kanehira Yamamoto (Japanese), Kent Williams (English)^{Foreign VAs}

The elder of the goblin village Rimuru meets and one of his first followers. After being given a name by Rimuru, he evolved and regained his youth and strength.

Bishōnen Line: Of all the goblins, his evolution had the most drastic effects on his appearance, becoming young, muscular and loud.
Black Eyes of Crazy: Invoked and played for laughs in The Slime Diaries, which shows him with black sclera and silver irises when he's truly furious at Milim's destructive antics.
Facial Horror: He gets half of his face burnt off by a punch from Phobio until Rimuru throws a healing potion at him.
Hidden Eyes: The majority of the time post-evolution, Rigurdo's eyes are completely blackened.
Miniature Senior Citizens: Before he was named, he was just as tall as the rest of the goblins, and was also the oldest to boot.
Large and in Charge: After evolving and being appointed as Goblin Lord by Rimuru, in addition to becoming young and muscular, he also grew a few feet to become taller than all the goblins under his leadership. Rimuru later designating him as the Goblin King to command over other Goblin Lords made him grow even more, making him bigger than even the other already-decently-tall Goblin Lords.
Large Ham: Rigurdo has a very booming and boisterous manner of speaking...that he frequently punctuates by flexing his muscles.
Older Than They Look: He was old and frail when Rimuru met him; now he appears to be in his thirties instead of his sixties with only his still-silver hair to indicate otherwise.
Silver Fox: Once he becomes a Hobgoblin, thanks to gaining a hulking mass of muscles.
Tears of Joy:
- Sheds these not only after being named himself, thus ensuring his evolution into a Hobgoblin, but also when Rigur is named.
- Sheds some more during a city-leadership-meeting about running Tempest, due to the sight of his son Rigur II having grown into such an intelligent and respectable young man as the city's ambassador.
Tranquil Fury: In The Slime Diaries Episode 7, he gets increasingly frustrated by Milim's constant destruction of property, but never actually blows up about it. Instead, he scares the crap out of Rimuru as he repeatedly shows the damage reports with increasingly harder slamming of said reports on the desk while smiling increasingly unsettlingly and giving crazier looking expressions while repeatedly affirming he's not angry at all.

Rigur II

https://static.tvtropes.org/pmwiki/pub/images/riguru_anime.png

Voiced by: Haruki Ishiya (Japanese), Derick Snow (English)^{Foreign VAs}

A young goblin and a son of Rigurd. Like all the other goblins, he evolved after being named by Rimuru, receiving his late brother's name.

Ambadassador: He acts as the primary ambassador in Tempest for fostering relations with other nations, and is so well-versed in the subject that his negotiations usually turn out favorably. Just because he focuses more on politics does not mean he's weak, though, as some Falmuth knights found out the hard way when trying to attack Tempest, joining Gobta in killing them effortlessly.
Bishōnen Line: Like the other goblins named, he evolved to become taller, more muscular and human-like.
The Dutiful Son: Whenever he's not helping the Goblin Riders, he's helping his father run the city.
Legacy Character: He is the second wielder of his name and he's very proud of it.
Minored in Ass-Kicking: His primary job focus in Tempest's leadership is acting as both an administrator of the country's politics and an ambassador for international relations, with fighting normally being delegated to those like Benimaru. But just because he doesn't usually fight isn't the same as him being unable to fight, as when a situation arises where him fighting is needed, he's still a named monster who acted as one of the defenders for his village before Rimuru's arrival made him stronger.
No-Sell: Managed to resist Shuna's sleep spell.

Ririna

Voiced by: Reina Kondo (Japanese), Sarah Roach (English)

One of the many goblins named and evolved by Rimuru, who was put in charge of Tempest's production affairs.

Ascended Extra: In the main story she acts as a background character performing her duties voicelessly, while The Slime Diaries focusing on the daily lives of Tempest means she becomes a prominent character due to the frequent plots involving food production.
Cute Monster Girl: She's a mature-looking woman who so happens to have green skin, silver-purple hair, and slightly-pronounced canines that all add to her image. Rimuru comments on her looks and attitude directly and admits she's attractive.
Platonic Life-Partners: She works very closely with Rigurd and there's definitely a sense of professional and personal loyalty on both sides.
Tsundere: Sweet type. She's usually all smiles and kindness, but she doesn't suffer fools and slackers well at all, as shown in The Slime Diaries Episode 8, where she grabs Gobta and his friends and starts talking like a mob boss to whip them into order. In the original Japanese, she changes dialects (which then get subtitles) while she's chewing them out, akin to someone with a cultured New England accent suddenly yelling at someone in Joisey.

Goblin Riders

Gobta

https://static.tvtropes.org/pmwiki/pub/images/gobuta_anime.png

Voiced by: Asuna Tomari (Japanese), Ryan Reynolds (English)^{Foreign VAs}

One of the many goblins named by Rimuru, and the only one who still looks like a regular goblin even after evolving into a Hobgoblin.

Acquired Poison Immunity: Gained Poison Resistance after surviving a bite of Shion's cooking.
Actually, That's My Assistant: After he defeats Gabiru, the latter becomes convinced that Gobta is the true leader of the village, mainly because he doesn't want to believe that he was clobbered by an underling.
Beware the Silly Ones: He acts rather goofy at times, but he's also quite skilled and shouldn't be underestimated. Case in point, he takes out the Lizardman Gabiru in single combat without an injury to his name, kills a charging Giant Spider monster on his lonesome when a group of human fighters were uneasy about facing it head on, and between himself and Rigur II, they take out the entire group of Falmuth knights defending a magic crystal creating the barriers around Tempest without much difficulty while Hakurou and Geld are fighting the Otherworlders.
Bishōnen Line: The only goblin to subvert it, becoming barely taller and hardly different appearance- or personality-wise. However, he still got the power boost after evolving.
Born Lucky: His side story illustrates this well; a branch he uses as a diving tool to find the way so happens to choose the correct path, he eats poisonous mushrooms and gets away with it because they are only poisonous when cooked, he happens to pick up a poisonous mushroom and throw it as well at a Blade Tiger, and when his Flame Blade is knocked away by the Blade Tiger in combat after he activates it goes straight into explosive poisonous mushrooms which kills the Blade Tiger. Sheer luck boosts Gobta's abilities as much as his natural talent.
Butt-Monkey: Basically, the comic relief of the series, and the target of the most Funny Background Events.
The Captain: Of the Goblin Riders.
Chekhov's Gun: In a side story, his Flame Knife, the magic tube the dwarves gave him, the poisonous and flammable mushrooms all come into play at the end to help defeat a Blade Tiger.
Chivalrous Pervert: He's a lovable guy who always comes through for Rimuru when it counts, and is a gentleman towards women in terms of physical stuff, but he is shamelessly honest about his perverted thoughts, with not even his lord Rimuru being spared from having his feminine appearance talked about, mainly comparing his flat chest to bustier girls. The blatancy of his ogling often results in a Pervert Revenge Mode from his targets.
Cowardly Lion: He can always be guaranteed to come through when it counts, but due to a case of Heroic Self-Deprecation preventing him from seeing how he keeps getting stronger and stronger, he always worries that somebody decently strong might be able to kill him and tries to deflect combat to a more obviously strong ally if possible, only standing his ground when nobody else is around as backup.
Crouching Moron, Hidden Badass: Despite his comical appearance and Butt-Monkey status, he is a Goblin Riders commander after all and very much skilled in combat when he actually gets a chance and motivation. Rimuru himself tends to forget this and often ends up surprised when Gobta pulls off a particularly impressive trick.
Curb-Stomp Battle:
- Sure he may have been heavily motivated/threatened, but his match against Gabiru was so one-sided that everyone watching it was surprised, some from how fast it was over, others (including Rimuru) that he won at all.
- His fight with the Night Spider was over in a flash, all because he was a bit hungry and the giant armored spider tastes surprisingly good when baked and boiled.
Friendly Address Privileges: As an official reward even! After the first battles of the Eastern Empire War, Rimuru granted Gobta the right to address him in the same casual manner that Gobta regularly does. One might think that this is a Dude, Where's My Respect? scenario; after all Gobta was being rewarded for essentially tangling with tanks while leading wolf cavalry. Instead, Gobta immediately notices that everyone else is jealous of him.
Fusion Dance: He can perform one with Ranga, combining their powers together and giving him, after Ranga's ascension, all the physical abilities and power of a True Demon Lord.
Genius Bruiser: Shockingly yes, Gobta is physically one of the strongest goblins in the world, while also being the only goblin with more than one unique skill. The unique skill 'Genius' makes him half this trope already, while 'Magic Wolf Summoner' allows him to summon and fuse with Ranga, basically fulfilling the bruiser part of this trope.
Has a Type: Generally likes goblina and elf women who are a lot taller than him.
Heavy Sleeper: While he and Rimuru are detained in the Dwarf Kingdom, he sleeps through the entire imprisonment.
Heroic Self-Deprecation: He's one of the best examples of taking countless levels in badassery among everybody in Rimuru's army, going from a total wimp to one of his best fighters, but he has heavy difficulties believing he actually got stronger, deluding himself into thinking he's at best Weak, but Skilled using powerful weapons and magic to compensate for his self-perceived weakness, even though time-and-again he's shown himself as a straight powerhouse when pushed to fight more determinedly.
Innocently Insensitive: He has absolutely no filter when it comes to speaking his mind, blurting out his thoughts with Brutal Honesty, which acts as a good way to perpetuate his Butt-Monkey status by acting as a revenge target for people he obliviously insults.
Iron Butt Monkey: A decent portion of his Butt-Monkey status involves getting pummeled into submission by people he's angered, but not only does he shrug it off and get back up little worse for wear every time, he actually prides himself on the fact he's tough enough to withstand blows from characters like Milim, who even when holding back leaves most characters on Gobta's level as heavily bruised, unconscious heaps.
Limited-Use Magical Device: His Flame Knife only has one or two charges left when he gets it.
A Lizard Named "Liz": Rimuru was running out of ideas when naming him, so his name derives from "goblin".
The Man in Front of the Man: Gabiru falsely assumes him to be the real boss with Rimuru as a Decoy Leader after Gobta beats him one on one.
Non-Standard Character Design: Not only does he still look like a goblin after being named, his head and nose are more round-shaped.
No-Sell: Managed to resist Shuna's sleep spell, ironically enough.
Sleepyhead: A running gag in the light novel (and to a lesser extent the manga and anime) is that nearly every time Rimuru turns away from Gobta, when he turns back, Gobta's taking a nap. This leads directly to Gobta being the first Goblin to be able to summon his wolf companion, which he did so because... they left him tied up as a punishment for sleeping and he really really had to pee.
Shadow Walker: He was the first goblin to replicate the Tempest Wolves' "Shadow Movement" skill.
Sheath Strike: His sheath doubles as a single-shot coil gun. It's notable in that it's the only gun that Rimuru allowed to be manufactured in Tempest at first because such technology would be devastating in the world's current tech level.
Strong and Skilled: Make no mistake, Gobta is this and has been for a long time. Not not long after his training under Hakurou began, he was able to beat Gabiru in a duel with ruthless efficiency (to the shock of Rimuru, Veldora, and Gabiru's subordinates).
Took a Level in Badass: Somehow this Iron Butt Monkey has become a dangerous fighter in his own right, but it got much better after Hakurou and Milim got their hands on him.
Underestimating Badassery: Not him, but most of the people he fights. Almost everyone he has clashed with in the series took him lightly and paid for it. The only one so far to not do this was Yamza, and he fared far better than everyone else who Gobta had fought, actually reaching a tie with Gobta.
Verbal Tic: He has a habit of ending many of his sentences with "-su".
What's Up, King Dude?: No matter how grand Rimuru's titles get or how much he moves up in the world, Gobta will forever refer to him casually like he was still that slime who saved the village from wolves. He's the only person who can get away with such casual address and Rimuru even makes it official that Gobta is the only one allowed to do so when he's rewarding Tempest's best soldiers after the first decisive victory against the Eastern Empire.
World's Best Warrior: While there are other goblins who are physically stronger at base, none of them have a unique skill, let alone two of them. By the end of the series, Gobta is very likely the greatest goblin warrior in the whole world in terms of pure skill and combat experience even without factoring in his ability to perform a Fusion Dance at will with a True Demon Lord.

Gobzo

Voiced by: Gakuto Kajiwara (Japanese), Clifford Chapin (English)^{Foreign VAs}

A hobgoblin who is a member of the Yomigaeri.

Back from the Dead: He was killed protecting Shuna during Falmuth's massacre of Rimuru City. Fortunately, he gets revived after Rimuru becomes a Demon Lord.
Came Back Strong: He is part of the Yomigaeri. Practically unkillable, with accelerated healing and durable souls as a result of being brought back to life, it's enough of a boost by itself to deserve working directly under Shion.
Hopeless Suitor: He's got a massive crush on Shion, but she only has eyes for Rimuru.
Non-Standard Character Design: He's even more funny-looking than Gobta.

Other Goblins

Rigur I

The original Rigur, named by Gelmud and killed during a Direwolf invasion.

Forgotten Fallen Friend: While he's mentioned a few times early in the story, he practically vanishes soon afterwards.
Posthumous Character: He's been dead for some time by the time he's mentioned in the story.

Haruna

Voiced by: Juri Kimura (Japanese), Megan Shipman (English)^{Foreign VAs}

A goblina resident of Rimuru City. She's in charge of sewing and cooking in Tempest.

The Apprentice: To Shuna, who taught her various skills such as textiles, cooking, and tea ceremony.
Bare Midriffs Are Feminine: She's a female goblin wearing a crop top that shows off her midriff.
She Is All Grown Up: Let's just say she's not the same little girl Rimuru met once he returns from his three-day long sleep.
Supreme Chef: She improved thanks to Shuna's tutelage to the point she makes Veldora's favorite dessert.
Textile Work Is Feminine: She learned from Shuna how to create silk and textiles.

Direwolves

Ranga

Voiced by: Chikahiro Kobayashi (Japanese), Tyson Rinehart (English)^{Foreign VAs}

A Dire Wolf that evolves into a Tempest Wolf after being named by Rimuru and later still into a Tempest Star Wolf. He and his pack became Rimuru's followers after he killed his father, holding no grudge against him.

Bash Brothers: Well, Bash Brother and Sister in this case, but he and Shion team up against Charybdis when the giant monster attacks.
Big Friendly Dog: After evolving. This becomes especially pronounced whenever he's in his true form, which is so big, it can hardly fit into the classroom of the Summoned Children.
Black Eyes of Crazy: Averted. The sclera in Ranga's eyes is completely black, and yet he's among the most noble members of Tempest.
Blow You Away: Receiving a name evolved him to a Tempest Wolf, giving him power over wind.
Canis Major: While being a direwolf already made him a good deal bigger than normal wolves, after he evolves he becomes outright massive in size, towering over most of the other characters, though he can shrink down to his original decently big size at will.
Curb-Stomp Battle: Poor Gregori was practically turned into Ranga's chew toy during their engagement, and even though one full potion healed him up, he developed a fear of canines as a result.
Defeat Means Friendship: After his father is killed, he and his pack swear complete allegiance to Rimuru.
Does Not Know His Own Strength: At first, he had trouble controlling the whirlwinds caused whenever his tail started wagging.
Evolution Power-Up: Evolves into a Tempest Wolf after being named by Rimuru, then later still evolves into a Tempest Star Wolf during the battle with the Orc Lord's army.
Gentle Giant: Ranga's true form towers over quite a few characters, but as long as they're on Rimuru's good side, he's easily one of the most affectionate wolves you'll ever meet.
Hive Mind: How he explains the reason why naming only him was enough to evolve all of the direwolves. According to him, they share one mind, and so by naming him, the current leader, the other wolves got to evolve as well.
Know When to Fold 'Em: Once his father is killed, and Rimuru uses his newly acquired "Intimidation" skill on him, he's the first to surrender to Rimuru's authority, with the rest of the direwolves surrendering soon after.
Loyal Animal Companion: Becomes one to Rimuru, acting more or less like his pet, and always by his side or hidden in his shadow.
Noble Wolf: Unlike his overconfident father, he is friendly and very loyal.
Not Quite Flight: By utilizing his wind manipulation powers to alter air density, he can "run" on thin air to simulate flight.
Shadow Walker: Ranga and all the Tempest Wolves have the "Shadow Movement" skill allowing them to hide and appear from shadows even a great distance away.
Shock and Awe: He can shoot lighting strikes from his horns.
Sizeshifter: He develops the ability to change his size after Rimuru gives him a name; he starts out massive, but later shrinks to merely larger than average for a wolf for practicality.
Supernatural Gold Eyes: His irises are golden, and both his fur color, star-shaped mark, and abilities after evolving make it quite clear that Ranga's quite supernatural compared to his fellow Tempest Wolves.
Turn the Other Cheek: Rimuru directly asks him about how he feels about the fact that Rimuru killed his father. Ranga admits that he still thinks about it but is much more grateful towards Rimuru for sparing the rest of the Dire Wolves when he had them at his mercy and then granting them a clan name, evolving them into Tempest Wolves. Rather than be resentful, he'd much rather show his thanks through his clan's Undying Loyalty.
Weather Manipulation: During the battle with the Orcs, he uses the wide-range attack "Death Storm", which creates massive twisters all over the battlefield coupled with lightning bolts powerful enough to kill an Orc General with one shot.
You Killed My Father: Subverted towards Rimuru, see Turn the Other Cheek above.

Kijin

Kijin in General

Color-Coded Characters: The colors of their hair and clothes match the ones in their respective names.
Colourful Theme Naming:
- Benimaru means "Crimson Circle"
- Souei means "Blue Shadow"
- Shuna means "Vermilion Vegetable"
- Shion means "Purple Garden"
- Hakurou means "White Old Man"
- Kurobee means "Black Middle Palace Guard"
Genocide Survivor: Out of a sprawling oni village, these six were the only survivors of a massacre by the Orcs. While this event massively impacted their lives, the kindness of Rimuru and desire for atonement from the Orcs, even at the potential costs of their lives, helped the oni-turned-kijin make peace with the tragedy, and drives them to aid Rimuru in his efforts to create a world where not only nobody experiences a tragedy like theirs again, but also one where nobody would become desperate enough to go through what the Orcs did for their own survival.
Hired Guns: What Rimuru originally figured his relationship with them would be. The Ogre Village was in the habit of hiring out its warriors as mercenaries before its destruction and as B-ranked monsters at minimum they are among the cream of the crop when it comes to the Jura Forest inhabitants, so the idea of letting them work for him in order to deal with the orc invasion and get payback for their people's slaughter seemed like a good idea. Then he decided to name them and suddenly he had six ride-or-die Kijin at his command.
Horned Humanoid: They all have notable horns on their person. They're notably relatively the same even after they evolve.
Immortal Procreation Clause: Their higher evolutions’ immortality and spiritual composition rendered them incapable of having children. Benimaru however held off on his evolution until after he successfully conceived his two children with Momiji and Albis.
I Owe You My Life: They were lost and confused after having their clan slaughtered before Rimuru gave them a purpose to live for.
Oni: Even though they were called ogres in their previous evolution, they are much closer to onis what with their horns and their Japanese like mannerisms and appearance.
Religious and Mythological Theme Naming: Three of them (Benimaru, Souei, and Shion) develop Ultimate Skills named after the Three Great Japanese Gods: Amaterasu, Tsukuyomi, and Susanoo.
Top Wife: Shion, Shuna (and, late in the series, Milim) are in competition over who will become Rimuru's "wife". Later, it's brought up that even if the two not chosen don't "marry" Rimuru, they could still be concubines.
Undying Loyalty: With a dose of Overzealous Underling mixed in. The Kijin could only be defined as fanatical servants to Rimuru due to him taking them in when the Ogre Village was destroyed and naming them, and early on even the slightest insult to their master could nearly lead to the offender's head parting ways from their shoulders as they barely held themselves back. Later on their self-control improves alongside realizing Rimuru would rather not murder willy-nilly over an insult, but a quick way to get their blood pumping is to not take a hint in shutting up on insults, and they won't hesitate to cut loose once Rimuru gives the all-clear.
Variant Power Copying: The Kijin gained improved versions of skills Rimuru either stole or developed. Benimaru got his Black Flames and improved it to become Hell Flare, Soei gained the Sticky Thread and Steel Thread skills, and Hakurou gained his Water Blade and improved it into the deadly Crestwater Slash.

Benimaru

Voiced by: Makoto Furukawa (Japanese), Ricco Fajardo (English)^{Foreign VAs}

Benimaru is an oni and loyal follower of Rimuru, as well as the son of the late ogre chieftain and Shuna's older brother. He is the Commander-in-Chief of Tempest and one of Rimuru's three strongest subordinates, along with Diablo and Zegion.

Acquired Poison Immunity: Played for Laughs; after taste testing Shion's food for so long, he gained the [poison resistance] skill.
Blood Knight: While all of the Kijin are quite eager to fight anybody that threatens either Rimuru or their companions, even after having his temper lessened following being saved by and pledging loyalty to Rimuru, Benimaru is still so Hot-Blooded he has a habit of trying to pick fights with anybody, including his own allies if circumstances permit friendly competition. It's to the point that he'll completely ignore all of Rimuru's specific instructions not to fight if an opportunity to do so presents itself.
Clueless Chick-Magnet: He's actually decently popular with women thanks to both his attractive post-evolution looks and manly personality, but he's such a major Blood Knight who views fighting as his only good point, he has some difficulties with both understanding when girls like him and dealing with their attempts to be friendly with him. Rimuru outright states that he drops pick-ups naturally without even being aware of it. That said, he later comes to comprehend women romantically wanting him, enough that he takes on both Momiji and Albis as his loving and beloved wives, even having children with both.
Does Not Like Spam: Despite looking and acting like a mature and serious man who will endure anything for Rimuru most of the time, he utterly hates vegetables (especially carrots) so much that he'll act like a whiny picky-eating child when they're part of his meals, doing his best to find excuses for avoiding them until Shuna does something that forces him to concede.
Elemental Hair Colors: He's a redheaded oni with fire magic.
Elemental Personalities: He's a fire magic user with a hot-headed personality that fits the element.
Frontline General: He's both Tempest's military commander and one of its most devastating fighters, and justified because his Unique Skill Born Leader allows him to receive real-time status updates on the battlefield and telepathically contact every soldier under his command while formulating and communicating tactics and strategies.
Hot-Blooded: Often fired up about things, and difficult to calm down once enraged.
Hypocrite: In his first fight with Rimuru he constantly calls him foolhardy and claims that his pride will get him killed, but when Rimuru tries to get him to back out by showing the then Ogres the difference in power between them, he claims that he cannot back down because of his pride. Recognizing the need to put his pride aside for the good of his people is what leads him to accept Rimuru as his master later on, though this aspect is mostly shown rather than discussed, and briefly at that.
One-Man Army: Effortlessly decimates huge portions of the Orc Lord's hundreds of thousands of soldiers relying entirely on his own magical abilities. During the assault on the magic crystals maintaining the barriers around Tempest, he slaughtered the group of Falmuth knights defending his target without aid, effort, or taking a single hit. By the time of the current time in the series (after 3 years), he's considered one of the strongest monsters serving under Rimuru.
Person of Mass Destruction: During the battle with the Orc Lord's hundreds of thousands strong army, he unleashes Black Flame attacks at will that create a massive Sphere of Destruction with each blast, sufficient that they can be seen from the air. He also destroys the revived Charybdis with a single Hell Flare that completely engulfed the beast until there's No Body Left Behind, to the shock of all present.
Playing with Fire: He had fire powers naturally as an ogre, and they were only strengthened after being named by Rimuru to the point he can also perform the devastating Black Flame spell, which becomes one of his signature moves.
Pre-Asskicking One-Liner: Gave a No, You version of this trope to a group of Falmuth knights, just before instantly wiping them out.
Falmuth Knight: "Halt! Come any closer, and we will show no mercy!"
Benimaru: "I'm the one who'll be showing no mercy. Sorry, but I'm going to take out my rage on all of you."
Red Oni, Blue Oni: He's literally a Red Oni, and he's hot-headed and passionate, which contrasts with Soei's Blue Oni.
Servile Snarker: While he has unquestionable Undying Loyalty, Benimaru isn't above throwing his lord Rimuru into an embarrassing situation for his own amusement. After Rimuru's ascension to a True Demon Lord and reviving the fallen of Tempest, including Shion, Benimaru throws his liege under the bus by goading him into admitting how he feels about Shion's cooking as a test to see if he still retains his reason. While Shion is holding him, no less, and Benimaru can barely hold back his amusement as Rimuru panics.
Sweet Tooth: In a surprising aversion of Real Men Hate Sugar, Benimaru loves sweets. It leads to Rimuru choosing him as one of the confectionery judges in the A Travel Guide to the Land of Monsters spin-off.
Telepathy: He gained it from Rimuru. It's what lets his Frontline General strategies work since he can give constant orders and get real-time updates.
Turn the Other Cheek: In spite of the fact that the orcs almost wiped out his species, he doesn't accept Geld's offer to take his head as penance. In his eyes, being a faithful follower of Rimuru is all Benimaru needs to forgive them.
Undying Loyalty: Towards Rimuru. He doesn't tolerate any kind of disrespect towards him. Conversely, as noted above, showing similar loyalty towards Rimuru is also a good way to earn his forgiveness.

Souei

Voiced by: Takuya Eguchi (Japanese), Ian Sinclair (English)^{Foreign VAs}

Tempest's spymaster and occasional negotiator, he's another of Rimuru's oni captains, responsible for information gathering and general security, which is aided by his ability to create clones of themselves that translate everything seen by them back to Souei.

Brains and Bondage: It's implied that Souei enjoys tying women up with his Steel Silk String ability: Souka fantasizes about it, and Litus is described as being "immobilized, squirming, and blushing heavily" after her fight with him (in the WN, Glenda is explicitly on the receiving end of this treatment instead).
Chick Magnet: Rimuru comments on what a stud he is multiple times and Souka, the Captain of the Guard of the lizard-folk, even defects to Tempest because she is enamored with Souei (and conveniently evolves into a human-like form).
Curb-Stomp Battle: When Rimuru gives him free reign, he cuts a swath through the orc guards so quickly and utterly that Souka is left speechless up until they rescue her father...at which point she can only sigh as he also starts gaping wide at the destruction he causes.
Dark Is Not Evil: His toolkit is very much that of a ninja assassin, including the extremely gruesome Steel Thread, and he has the cold personality to match with perhaps a hint of sadism (as indicated by his use of said Steel Thread), but he still serves The Good King Rimuru.
Doppelgänger Attack: His Replications on paper can be used for this, as they copy his physical abilities perfectly. However, they cannot copy anything higher than his bare basics Skills, so he rarely uses them for direct offense and instead relies on his mental link to them for recon and information gathering. They do make for great expendable fighters in a pinch, as Glenda learned to her regret when she wasted her ace-in-the-hole on one.
Hidden Depths: Underneath his stoic, no-nonsense attitude is a person who really cares about his loved ones and has more childish tendencies, which Souka notices and absolutely loves. In The Slime Diaries, he adopts a small black cat that he plays with (and practices dramatic one-liners on).
Hiding Behind Your Bangs: His hair usually covers his right eye, fitting his stoic personality and occupation as a ninja.
Master of Threads: He uses Sticky-Steel Thread to completely wrap around a target and bind them in a cocoon.
Ninja: Rimuru introduced Souei to the concept of and tropes surrounding ninja, which Souei embraced with great enthusiasm.
Not So Above It All: The Slime Diaries Episode 10 reveals that after he helped Rimuru pipe in the hot water from Veldora's cave to make the main Tempest communal hot springs, he proceeded to pipe a personal hot tub on his own time to his house.
Not So Stoic: There are few ways to get a rise out of Souei; Shion's cooking is one of them.
Oblivious to Love: Souei fails to notice Souka’s crush on him despite how obvious it is. Either that or he has noticed but chooses to not acknowledge it for the sake of professionalism.
Razor Floss: Inherited Steel Thread from Rimuru after being named by him, which becomes one of his signature techniques.
Red Oni, Blue Oni: He literally is a Blue Oni, and he's calm and composed to contrast Benimaru's Red Oni.
Screw This, I'm Outta Here: One of his Running Gags is whenever a situation involves Shion's cooking or Shuna's ominous smiles, he'll get the hell out of dodge immediately.
Self-Duplication: He can cast off clones of himself through [Replication] that are constantly connected to him, which is extremely useful in his craft. In a pinch they can even be used offensively, but while they copy his physical stats and abilities they only receive barebone copies of his Skills, making them much weaker than himself in a fight. By the time of the final battle of the Tempest-Empire War, he obtains [Parallel Existence], the highest form of duplication that creates exact copies of himself down to the mind and soul to the point that even if the "original" him is killed, he can survive as long as even one Parallel Existence remains, and they also possess all of his Skills. However, there is a temporary loss of power for the time it takes for the magicules split off into the now-destroyed Parallel Existence to remerge with the surviving copies.
Ship Tease: Downplayed. In regards to Souka's crush on him, there are generally little signs that he feels the same way. However, in the "Slime Diaries", he reveals to Benimaru that he sent her with Rimuru and the others to act as a bodyguard for their beach trip and speculates Shion and Shuna are likely picking on her, prompting Benimaru to remark that he's always harsh on those he likes, to which he only respond by saying "[My] love is deep", still leaving his exact feelings up in the air but hinting that he holds a degree of fondness for her.
Slasher Smile: His smile is the most terrifying thing about him. He typically only shows it when he is about to make someone suffer.
Stealth Hi/Bye: Not only does he often use his Teleportation skill to pop up near other characters unexpectedly, he sometimes does so without a telepathic warning, resulting in even Rimuru getting startled.
The Stoic: Rarely shows much emotions and acts very calm at matters.
Teleportation: His movement techniques are so good he essentially does this to get anywhere he needs to in short order. This ability is so handy that Rimuru at one point actually expresses envy about not having it himself.
Tranquil Fury: When a lizardman voices his opinion that he thinks Rimuru's simply come running to them in fear of the Orc Lord. Souei immediately strangles a steel thread around his neck hard enough to draw blood. Their chieftain notes he probably would've taken his head off completely had he not apologized on his behalf.
Wrecked Weapon: Wrecks his sword on Rimuru's Body Armor during their clash before being punched into a tree.

Shuna

Voiced by: Sayaka Senbongi (Japanese), Tia Ballard (English)^{Foreign VAs}

The daughter of the late ogre chieftain and Benimaru's younger sister. Very skilled and knowledgeable in domestic matters, she essentially becomes Rimuru's chief economic advisor together with Rigurdo.

A-Cup Angst: Despite not being flat-chested herself, in Slime Diaries, she reacts with barely-subdued rage and jealousy whenever Shion flaunts her much larger bust.
Adaptational Badass: Gets a bit more of an active role in her first appearance in the anime compared to the manga. She's introduced conjuring a massive wall of flames to protect her ogre allies from Ranga.
Almighty Mom: She effectively had a Promotion to Parent over Benimaru after their parents died in the clan slaughter, and any time Benimaru starts getting a bit unreasonable in attitude, when Shuna puts her foot down and makes sure none of his excuses will work, he concedes defeat and does what she wants.
The Archmage: She's second only to Diablo in terms of knowledge and skill over magic, and with the Manufacturer skill she's able to use that magic comprehension to create and use any and all kinds of magic she can think of, even if it's magic a monster like her normally wouldn't be thought possible of using, like holy magic. She almost becomes on par with Diablo in magical might by gaining Law Manipulation, turning into a magic-based Reality Warper with very few limits.
Attack Reflector: One application of her Manufacturer Unique Skill is called "Overdrive", which applies the magic dismantling and repurposing aspect to an opposing enemy's magic, allowing her to "overwrite" control of the spell and turn it against the caster.
Barrier Maiden: Alongside Myulan, it's her job to preserve the souls of Tempest's fallen during the "war" with Falmuth with her magic long enough for Rimuru to ascend to True Demon Lord status and properly revive them.
Beware the Nice Ones: As sweet as she is, her wrath is something to be feared, and when Benimaru spoke of how he won't forget the name of Footman (the masked maijin who destroyed their village), Shuna firmly agrees with him. Plus she mastered Disintegration in a frighteningly short time and has fine-tuned control of what she wants destroyed.
Character Tic: She has a habit of holding up one of her sleeves to her mouth when talking about something serious.
Clap Your Hands If You Believe: She's adept in the use of Holy Magic, something that's considered especially unusual because most Holy Magic is associated with religious institutions with a Fantastic Racism against monsters. While Holy Magic is usually fueled by a pact with one's God, Shuna gets around this by fueling it with her unwavering faith in Rimuru, making her ideal when facing enemy monsters weak to Holy power.
Cute Monster Girl: She looks like an adorable pink-haired girl with oni horns.
Cuteness Proximity: Just like Shion, she uses every chance to cuddle with Rimuru's blob form.
Excellent Judge of Character: Shuna was the first to see that Rimuru wasn't the one who slaughtered her home, given how he had immense strength but didn't kill any of them when he easily could have.
The Fashionista: She works for the Tempest's fledgling garment industry in both making the garments and deciding the trends.
Feminine Women Can Cook: She's more feminine than the bruiser Shion and definitely the better cook of the two.
Forced Sleep: Managed to incapacitate most of the Goblin village patrol using this sort of spell, though a couple of them managed to resist it.
Formal Characters Use Keigo: Being raised as a princess, Shuna possesses a refined and graceful personality, which is reflected in her very formal linguistics.
Hidden Depths: She can play the piano like a master, wowing the crowd at the Founding Festival in her duet with Shion.
Honorary Princess: She's nicknamed "Oni Princess" by Rimuru because of her status as the daughter of the late ogre chieftain.
Like a God to Me: Shuna's unyielding faith in Rimuru allows her to use Holy Magic, which is usually fueled by the user's faith in a particular god. Adalman is so impressed by this that he asks to be introduced to the one that could compel such faith in Shuna, though Shuna tries to say that though she respects Rimuru a whole lot, she (nor the others) don't necessarily worship him.
Miko: She dresses as one and can even use Holy Magic, which astounds Adalman as he thought it was impossible for monsters to use it. It does help that she has Holy-Demonic Attack Resistance, but it's possible for her because she has unshakeable faith in her "god" Rimuru, which fuels the magic.
Playing with Fire: Like her brother, though her flames are blue.
Reality Warper: She gains this via Law Manipulation, which allows her to alter the world itself based on her knowledge of magical and scientific laws.
Rose-Haired Sweetie: She's a very sweet-natured girl with pink hair.
Single-Target Sexuality: She only has eyes for Rimuru.
The Social Expert: Her princess training gave her politics training. Rimuru leaves most of the talking to her whenever he can.
Squishy Wizard: While Stronger Than They Look is in full effect considering she's a member of a race known for physical strength, Shuna's strength and durability are on the low end for someone of her ability. However, her mastery of magic is only matched by some of the strongest in Tempest above her weight class, especially once she masters Law Manipulation.
Straight Man: She plays one to Shion, who is more of The Ditz, when it comes to her secretary work.
Supreme Chef: Unlike Shion, her cooking is considered the best in Tempest, and she often proposes new additions to the nation's exports.
Team Mom: She acts as the primary emotional center for all of Tempest, keeping people in line through a motherly attitude and making sure everybody's livelihood is well-kept, which also includes nudging them into doing things they dislike when it's good for them. It's even lampshaded that she's literally like a mom to her brother Benimaru in particular, taking on a Promotion to Parent-type attitude when he starts acting childish.
Textile Work Is Feminine: Shuna shows off her femininity by showing her skill in weaving silk on a loom. Shuna is made responsible for clothing everyone in their fledgling village and had already woven several rolls of silk.
Tranquil Fury: In a contrast to her brother Benimaru, who is quite blatant when he gets angry, when Shuna gets angry she stays as calm and composed as she is normally, with her rage instead being expressed through a chilling stare and a calm smile or frown, along with exuding a terrifying level of Killing Intent. Her joining the fight against Adalman exemplifies this best, where her expression becomes at worst a glare of disappointment, while her words and actions show that she's holding in a lot of Suppressed Rage over the whole chain of events that began with the attack on their village, and took this opportunity as an outlet for her fury.
Undying Loyalty: To Rimuru, will do anything he asks of her and will follow him to the end; she even has immense feelings for Rimuru as well.
Weak, but Skilled: In terms of raw power, Shuna is actually the weakest oni. Where she shines is in her complete mastery of her powers, allowing her to use them with maximum efficiency and effect.
Yamato Nadeshiko: Shuna is always calm and dignified, educates Rimuru on proper etiquette for nobility, and dresses as a miko.
Yandere: Played for laughs in Slime Diaries, with Shuna's Beware the Nice Ones traits and rivalry with Shion over Rimuru being exaggerated. When Shion complains about her kimono being too tight around her chest, Shuna — while not exactly flat-chested herself — giggles and flashes a Psychotic Smirk coupled with Empty Eyes as she says that large chests get in the way of dressing.

Shion

Voiced by: Mao Ichimichi (Japanese), Michelle Rojas (English)^{Foreign VAs}

An oni, Shion is Rimuru's Chief Secretary in charge of his personal care, though she's rather disappointing at her job. Shion is amongst the strongest of Rimuru's fighters, wielding a large odachi forged by Kurobee. She is completely loyal to Rimuru and becomes enraged at any slight against her master.

Accidental Misnaming: As she's primarily Dumb Muscle when working as Rimuru's secretary, when Rimuru tasks her with "interrogating" the survivors from the Falmuth army massacre (in the anime, at least, since he personally "interrogated" them in the manga), she repeatedly has problems remembering the names of them, resulting in a lot of confusion over who she's talking about each time a new person is brought up. By the end of the info delivery, she's whining out of embarrassment at Rimuru seeing her acting so incompetent. Even worse, she managed this despite competently writing down just about everything else they told her, but butchered the names so horribly in her notes.
Action Girl: Goes without questions. She's on par with Benimaru in the fighting department.
Almighty Janitor: Her official position is Rimuru's primary secretary and his top bodyguard, but this belies the fact that she's one of the strongest people in Tempest and it wouldn't be an exaggeration to say she could stand a good chance of facing down with the acknowledged strongest fighters in Tempest and come out the winner. Even Ciel admits she's one of the few in Tempest who actually could stand a chance of defeating Rimuru in a fight if she ever reached her true potential.
Back from the Dead: She gets killed during the church's initial massacre on Rimuru, though she's later revived along with a new evolution.
Badass in a Nice Suit: Unlike the other Oni, who still wear their more traditional clothing, Shion switched out to a business suit to better fit her role as "Chief Secretary" and is certainly one of Rimuru's more powerful followers.
Berserk Button: Shion gets quite offended when people offer her cooking as a punishment, including Rimuru himself.
Beware the Nice Ones: Ever since Rimuru took her in and gave her life greater meaning, she became one of the kindest and sweetest characters in the story, moreso than even Rimuru himself. However, while she's always open to giving companionship or a helping hand to others, that does not mean she has in any way become a pushover. She considers Rimuru her very reason for existence, and anything that either insults or threatens him and his country, including everybody she calls her comrades, will push her into a serious fury. She ends up taking the scariness of her anger even further once she gains the "Chef" skill, as it also grants her the power to inflict Body Horror on her enemies so long as they're at least marginally weaker than her stat-wise, which she puts to good use on two of the surviving members of the Falmuth Kingdom massacre, turning them into writhing masses of flesh, bone, and skin that were still alive, constantly twitching without the ability to even scream about their agonizing state.
Beware the Silly Ones: Shion is mainly a fanservice and comic relief character; her status as the Dumb Muscle means that her only true value is on the battlefield. However whereas Ciel was helping practically all of Rimuru's executives evolve and achieve Ultimate Skills, Ciel all but actively hindered Shion's evolution. It is because out of all of Tempest's citizens, Shion is the only one who could evolve an Ultimate Skill that could potentially kill Rimuru. Not the True Dragons, not the Primordial Demons, not the Insectars; it is Shion alone that Ciel is wary of allowing to possess more power than she already has.
Big-Breast Pride: She's fairly proud of her well-endowed figure, and wears cleavage-heavy outfits to show it off.
BFS: Has a sword that's almost as long as she is tall and almost as wide as she is, which she easily handles. It puts one in mind of a skinny Tetsusaiga.
Bodyguarding a Badass: She's officially Rimuru's secretary and bodyguard and she's certainly capable in the latter category, but given who Rimuru is the number of things she'd be more capable of defeating over him are in a minority.
Boob-Based Gag: While her massive breasts are mostly played for fanservice, they also are used for comedy, such as her habit of resting them on top of Rimuru's head in both slime and human form, the A-Cup Angst they induce in lesser-endowed women, and the goofy sound-effects they make when bouncing.
Buxom Beauty Standard: She has a sizable bust that is the focus of many Male Gaze shots and is a source of jealousy to the other girls, especially Shuna. Rimuru was actually distracted by her cleavage during their initial fight and commented on how big they were. They are emphasized more in the anime adaptation, where they are drawn many times to each be bigger than a person's head◊.
Came Back Strong: Her death and resurrection granted her reality-warping abilities as well as both a Healing Factor and the ability to retain all her memories despite receiving fatal wounds or mind manipulation.
Can't Hold Her Liquor: She quickly gets inebriated during the meeting between Rimuru and Gazel and just keeps pouring from the bottle and drinking from her glass, all while happily and drunkenly proclaiming that the trade deal with Eurazania they're discussing as important for Tempest's situation is all but guaranteed. Judging from Shuna's reaction, this has been a thing since she was still an ogre. Luckily, Gazel is rather openly amused by her antics (helping that she didn't actually break anything and just fell over on her back once she was done).
Carry a Big Stick: She used a spiked mace when she was an ogre until she switched to a large sword.
Curb-Stomp Battle: She hands Clayman an absolutely brutal one during Walpurgis. All his magic is at best just a distraction or annoyance to her while most of it she just No Sells, and while she gives him credit for being able to fight in melee with his One-Winged Angel form she expends only a middling amount of effort to outspeed and overpower him before chopping off all his limbs.
Cuteness Proximity: She finds Rimuru's base slime form extremely cute and is rarely seen in a situation where she isn't simply holding him like a pet.
Dark Is Not Evil: Despite her race being “Wicked Oni” and her being classified as a “Disaster-class” monster on par with actual Demon Lords as Clayman found out, she’s a sweetheart to her friends.
D-Cup Distress: She's usually all about Big-Breast Pride, but she expresses a dislike of wearing kimonos specifically because of this as the process of making her appear less endowed to fit the clothing squeezes her boobs tightly against her chest, which causes her discomfort.
Depending Upon the Undependable: She's certainly a powerful fighter, but not much else, making Rimuru's decision to appoint her as his secretary questionable to say the least, though we can certainly think of two big reasons. What's more, her uncontrollable wrath over any perceived slight against Rimuru, her tendency to get drunk easily, and so on make her a catastrophic liability on any diplomatic mission. Rimuru himself has grown savvy to this, but he's all but locked into relying on Shion anyway, because any attempt to exclude her from a mission results in a tantrum, and with her immense Super-Strength, her tantrums are of city-destroying proportions.
Does Not Know Her Own Strength: Occasionally happens, like when she charged up a magic attack to fire at Suphia but everyone decided that was enough fighting to prove Tempest's strength to Carrion's warriors... unfortunately she couldn't stop charging the attack nor could she lift it enough to fire it into the sky, forcing Rimuru to have her fire it at him so he could absorb it with Gluttony and not have it explode with enough force to likely kill almost everyone on site.
Dumb Muscle: Has enormous strength as a Kijin but rarely thinks things through and instead brute forces them. Even when she does use her brain, it's usually only to figure out how to better apply her brute force to the problem at hand, in turn usually by how to best use Chef. It took her battle with Razul, one of the most powerful warriors of the Western Nations and a monster legitimately stronger than her, before she could truly appreciate the value of skill paired with strength.
Healing Factor: Eventually gains Ultraspeed Regeneration, which allows her to regenerate damage to her body constantly and nigh-instantly from almost anything short of atomic destruction. It's only weaknesses are that attacks on her soul won't be healed by it and it can't heal wounds to her body caused by spiritual-based attacks. It eventually upgrades to Endless Regeneration, which removes even those weaknesses.
Heart Is an Awesome Power: Following her experience with dying and coming back to life, she ends up acquiring the "Chef" skill. While the name makes it sound like it simply gives her the ability to genuinely cook, in reality she was such a horrible cook that instead it turns her into a small-scale Reality Warper, giving her the ability to re-write the very existence of any object weaker than her to follow her will. While normally she applies this to make anything she cooks taste just as good as if it was cooked properly, she's also capable of using this threateningly, such as making good-looking food that tastes like death, or altering the bodies of Rimuru's enemies to turn them into twitching masses of still-living flesh. She can even manipulate minor wounds she deals her foes to become giant fatal ones. Chef eventually evolves into Tyrant King Susanoo, which upgrades this ability into having control over causality and immunity to Time Stands Still.
Hidden Depths: Shion is a talented violin player, something most don't expect from the Dumb Muscle.
Implacable Woman: After dying and coming back, she gains a combination of the skills Ultraspeed Regeneration and Perfect Memory. The former gives her a powerful Healing Factor, while the second not only allows her soul to revive from death safely as long as it itself isn't damaged, she also retains all her memories perfectly no matter what. This turns her into a fighter who can just power through most direct, even fatal, attacks without worry as her body reassembles itself and her soul just plugs itself back in when its done if the damage is serious enough, and she herself is also immune to mental manipulation as proven when Clayman tries to do so against her.
Impossibly-Low Neckline: Her jacket has a very low neckline that exhibits a good amount of her cleavage.
Lethal Chef:
- Even though she has no malicious intents, her cooking always ends up as something incredible abhorrent to the point of appearing like warped eldritch monsters. To survive a spoonful of her "food", Gobta actually had to learn the skill poison resistance. Being forced to eat Shion's cooking is an actual punishment in Tempest.
- In The Slime Diaries Episode 1, she accidentally spills some of her tea on Rimuru and Great Sage immediately triggers "emergency measures" by activating Pain Nullification, Ailment Nullification, and Self-Regeneration while the purple stuff is bubbling and boiling over his slime form. All subsequent cooking-and-serving-related skits which include her have a secondary joke about everybody doing their best to prevent her from so much as touching any of the ingredients.
- She eventually manages to work around this by way of acquiring the "Chef" skill that allows her to make genuinely good food. It doesn't improve her actual cooking skills, however, and instead allows her to overwrite whatever she cooks to taste how she wants, such as when she cooked macarons in The Ways of Strolling in the Demon Country, which despite looking more like masses of tentacles and eyes vaguely shaped like the food still tasted quite good.
Lightning Bruiser: In addition to her utterly monstrous Super-Strength, her speed is so great that she can Flash Step to get in the faces of her enemies near-instantly before executing Rapid-Fire Fisticuffs on her current opponent. That's not even getting into her Implacable Man status with Ultraspeed Regeneration and Perfect Memory, meaning even if you manage to find an opening in her frankly Unskilled, but Strong attacks, you'll learn that she doesn't go down easily.
Man of Kryptonite: The main reason Shion's "fight" against Clayman was a Curb-Stomp Battle is because all of his usual tricks were useless against her.
- Clayman tries using his puppets possessed by souls, only to learn that Shion's Soul-Cutting Blade is able to kill them, preventing them from repairing themselves.
- He tries to use a spell to pull a People Puppets, but after her resurrection, Shion gained the skill Perfect Memory, which besides doing Exactly What It Says on the Tin, also makes Shion completely immune to mind magics.
- As for getting physical...Shion's an Action Girl, while Clayman's a Non-Action Guy. Even going One-Winged Angel didn't help him even the odds.
Might Makes Right: She was a firm believer of this for most of her life, and it took her first death and resurrection to realize the contradiction.
Ms. Fanservice: She's an attractive woman who's tall with an impressively gaze-snatching large chest, and she's pretty much the primary target for fanservice scenes, mainly focusing on how she likes to rest her bountiful breasts on top of Rimuru's head, in both slime and human forms.
Nice Girl: Insults to Rimuru or her cooking aside, Shion is a very nice person when not in battle. It becomes a bit of a Running Gag that whenever someone comes running to Rimuru with a problem and begs him to help, if Rimuru isn't on board at first or with doubts, Shion if sufficiently moved will put him on the spot by declaring of course he'll help because he's the noble and just hero and leader and giving him no room to refuse without looking bad. Of course, this is because she genuinely believes Rimuru will, and Rimuru himself admits he can't really say no to someone in need anyways.
Overzealous Underling: Shion tends to go for overkill as her first option whenever confronting an enemy, problem or life in general. In a more literal interpretation, Shion's complete and utter faith in Rimuru's generosity and benevolence tends to get him stuck in situations he would rather avoid.
Sexy Santa Dress: Wears one for the Christmas Episode of The Slime Diaries, with Rimuru lampshading it.
Sitcom Archnemesis: With Shuna...and Ranga...and Diablo...really, with anyone who wants a portion of Rimuru's time.
Soul-Cutting Blade: After her revival and the attack on Tempest, Rimuru has Kurobee forge her a new BFS incorporating properties from Hinata's Dead-End Rainbow sword, which allows her to attack the foe's soul alongside their body. While she can't perform the guaranteed "kills in seven strikes", Shion's sheer strength usually means even one well-placed blow will be an instant-kill.
Strong and Skilled: Shion starts out as Unskilled, but Strong, relying on her innate strength, BFS, and ferocity to win most battles. As time goes on, her Healing Factor and Chef Skills add more options to her arsenal to just steamroll her enemies, but she begins putting more effort into proper swordsmanship, tactics, and battle smarts to maximize her abilities in part because she wants to impress Rimuru and show up Diablo, who is also an example of this.
Subordinate Excuse: While many of Rimuru's female (and even some of the male!) subordinates harbor feelings for him, Shion takes it the furthest of them all.
Superpower Lottery: Her Chef Unique Skill makes her a small-scale Reality Warper whose only real limits are against enemies who just straight-up outclass her with no chance of victory, and as she becomes stronger and more skilled the number of people who do so shrink each day. Even against enemies who have the advantage on her, her ability to always determine the optimal actions necessary as well as guarantee the results she wants as long as she can get the ball properly rolling mean she just needs to try harder until she gets her way. Chef is so broken, in fact, that it's on par with an Ultimate Skill on its own and Ciel originally didn't evolve it but a different Skill of hers when she gave Rimuru's other top subordinates Ultimate Skills because she knew Shion would be among the few beings on the planet legitimately capable of killing Rimuru if it became any stronger. Shion had to evolve it into Tyrant King Susanoo on her own.
Super-Speed: During her fight with Clayman, Shion demonstrates the ability to move a high speeds sufficient to completely outmanuever her Demon Lord Seed-level foe and strike multiple times in an instant.
Super-Strength: A single swing from her sword can create a Sword Beam that carves through the earth and sends dozens of Orcs flying away. Her raw strength alone is enough lift an uprooted fully-grown tree with one hand like it's nothing. After she Came Back Strong, she can overpower a Demon Lord Seed like Clayman with brutal ease. She only gets stronger when utilizing the Skill [Ogre Berserker] and its upgrade [Battle God], which increases her physical strength many times over in exchange for consuming a massive amount of magicules while it's activated, which isn't as crippling as it sounds because Shion has one of the highest magicule counts in all of Tempest.
Super-Toughness: During her "fight" with Dagruel's sons, one of them tried to kick her in the head. His leg broke on impact while she wasn't even phased.
Sword and Fist: While she prefers to use her sword, her fight with Suphia shows she's fully willing and capable of holding her own in hand-to-hand combat.
This Is Unforgivable!: She makes clear to King Edmalis and Bishop Rayhiem that she is very unhappy that Rimuru was forced to kill humans as an unwanted necessity for reviving her.
Tragic Bigot: She nearly becomes this towards humans after the Falmuth Invasion. Subverted after an honest apology from Hinata for her involvement in the attack convinces her to give them another chance.
Undying Loyalty: Toward Rimuru, on the same level as Benimaru, no doubt, if not more loyal.

Hakurou

Voiced by: Hōchū Ōtsuka (Japanese), Charlie Campbell (English)^{Foreign VAs}

An elderly swordmaster whose skill was already legendary even as an unnamed ogre, but after being accepted and named by Rimuru he gets even stronger — not to mention getting his physical prime back.

Awesome by Analysis: He's able to correctly identify the skills Rimuru uses to incapacitate Kurobee, Shion, and Souei and the monsters they originate from just by seeing them used once. He's also able to identify Kyouya's use of the Space element after seeing it used against him.
Badass Boast: Gives one to Razen's We Will Meet Again, saying that it would be impossible for that to happen after Rimuru was done with Falmuth.
Razen: "So long as you live, we may meet again on the battlefield."
Hakurou: "That will not happen. Our ruler is making his way toward that battlefield."
Razen: "Your ruler? Was he not defeated by that witch, Hinata Sakaguchi? He still lives."
Hakurou: "You people have gone too far. You angered the one person whose rage you should fear the most. You have my sympathy. Your death will not be painless."
Badass Teacher: About as badass as they come. Everyone who trained under him became a badass in their own right. This included King Dwargo, Rimiru, Yohm, and even Gobta to an extent.
Berserk Button: He really doesn't like being called "old man" due to both noting his age and seeing it as a show of disrespect. Gobta tends to learn this the hard way during their training.
Clark Kent Outfit: The vast majority of the time he wears big, baggy, largely-encompassing oufits that only expose his head and hands, so it can come as a shock any time he wears outfits that expose more, from just wearing sleeveless shirts and shorts up to wearing a fundoshi swimsuit that shows almost everything, which show that he's actually utterly ripped for a man who is physically still decently elderly.
Doting Parent: He quickly turns into one when he learns that he had a daughter from his one night stand with the Tengu leader Kaede, to the point he's all for Benimaru marrying said daughter Momiji.
The Dreaded: While many across the land hold a mixture of awe and fear for his impressive abilities, those who are the most terrified of him are anybody acting as his students, since he puts everybody under him through Training from Hell. While all of said students go on to become mighty warriors due to his teachings, the majority of them still dread his lessons.
Drill Sergeant Nasty: He trains Tempest warriors (including Rimuru himself) in swordsmanship, and is notoriously strict at that.
Famed In-Story: Even from the time when he was an unnamed ogre, referred to as the 'Sword Saint'. countless people across the land knew of and were in awe at the sheer power and skill he possessed, to the point that being trained by him was considered a high honor. Many of those trained by him also fit this trope, included the Dwarf King Gazel himself.
Hidden Depths: As proven during the Founding Festival, Hakurou is a master at fish-related dishes, expertly carving up and filleting the fish and serving it up with a practiced flair. Even Shuna admits he's better than her at it.
Iaijutsu Practitioner: His primary method of fighting is a quick-draw slash with the intent of decapitating the opponent. After getting a power boost from Rimuru, Hakurou's attacks have become so fast, an enemy with Super-Reflexes is unable to react fast enough to stop Hakurou's blade from cuttitng his head from his shoulders.
Inexplicably Awesome: Even back when he was an unnamed ogre, he was well over 300 years old. An impressive feat for a race whose average lifespan is 100. Becoming a famous swordsmaster that people activly sought out and training legendary figures without being a named monster also stands out.
Kill It with Water: Water formed into an Absurdly Sharp Blade, at least. His technique [Crestwater Slash] is basically Rimuru's [Water Blade] taken to the logical extreme, moving so fast that [Thought Acceleration] cannot keep pace with it. Kyouya found this out the hard way.
Luke, I Am Your Father: He had a relationship with Kaede, the Tengu Village Elder, when they were students under his grandfather, and she was pregnant with Momiji. Both Benimaru and Rimuru were surprised when they found out about their relationship and how he had a child without realizing she exists.
Master Swordsman: One of the greatest swordsman of the current era, known as the Swords Saint. Even back when he was a nameless ogre, he managed to bypass Rimuru's Magic Sense and defensive skills to cut off his arm during their initial fight, and only expressed disappointment that he didn't hit his head like he intended.
Miniature Senior Citizens: Before being named he was the shortest of the ogres, being a scalp smaller than the soon to be named Shuna.
Mundane Utility: Incredibly badass sword skills, surprisingly enough, also come in handy when one needs to fillet a giant fish for dinner...
Older Than They Look: Like Rigurdo, he was already an old man when he met Rimuru, but got rejuvenated after being named and evolving into oni. Though he's not a man in his prime like the latter and is more of the late middle age, suiting his image of an Old Master.
Old Master: A textbook version, from the look to the function, though after evolving he gets a bit younger than the standard.
Red Baron: The Sword Saint.
Shout-Out: His appearance is basically a Palette Swap of Toshizou Hijikata from Golden Kamuy, similarly being wiry old men with thin wispy beards and mean sword skills, though Hakurou wears white clothes instead of Hijikata's pin-striped green suit, and obviously lacks the latter's favourite Winchester.
Sore Loser: Rather self-deprecatingly calls himself one when Kyouya tries to mock him for coming for a rematch despite how their fight in Tempest went. Although in his case, it was more being "sore" about losing to someone he should have had no problems beating without outside interference.
Super-Speed: Not only can he move faster than the eye can track, but Kyouya's [Hyper Acceleration], which allows him to perceive and react to the world at 300x normal speed, couldn't keep up with him.
Third Eye: When he gets serious, his forehead splits open to reveal one that's black and blue.
Took a Level in Badass: While all of the monsters that Rimuru names become more powerful and gain new skills, Hakurou stands out in that his age affected his abilities and he was physically much weaker than he was in his prime. After he's named by Rimaru, he not only gets stronger by becoming an Oni, he also grows younger giving him a body more in its prime with centuries worth of experience with the sword.
Weak, but Skilled: Downplayed as he was still an Ogre and much stronger than most humans or monsters but old age affected his abilities and physical strength. This continues even after he's named by Rimuru and becomes much younger to reach Strong and Skilled, as Rimuru would prefer actually not putting him at the head of any strenuous adminstration duties outside of teaching.
Worf Had the Flu: He only lost his initial fight with Kyouya Tachibana due to two barriers over Tempest cutting his available strength to a fraction of its usual. When they have their rematch outside the barriers barely days later, Hakurou shows that Kyouya's only chance of victory was with that handicap, and not even the arrogant and increasingly desperate swordsman's best can do much to phase Hakurou before he ends it.

Kurobee

Voiced by: Junichi Yanagita (Japanese), Eric Vale (English)^{Foreign VAs}

The last of the oni, and, similarly to Shuna, not very martial. Instead, he's a master artisan and quickly befriends Kaijin, working with him as his chief blacksmith.

Ascended Extra: Similarly to the overall goblin race, The Slime Diaries focusing on daily life in Tempest means Kurobee loses his Out of Focus status, being bumped up to having almost as much screentime as the other kijin, though most of his appearances are understandably spent forging things or talking about blacksmithing with Kaijin.
Birds of a Feather: He and Kaijin become friends soon enough because of their shared passion for blacksmithing.
Bishōnen Line: Very notably downplayed compared to Benimaru and Souei, as while he lost his original oni monstrosity like them, he ended up looking more like a pretty-average middle-aged man after being named than the twenty-something hunks they did, which Rimuru comments on and manages to feel some level of kinship to given his past life.
The Blacksmith: He is the primary ironsmith out of Rimuru's kingdom, and in fact was the person who created tools and weapons for the oni back when their village was still around. After becoming a kijin, he gets elevated to a borderline Ultimate Blacksmith, with many of his works being legendary in strength... though sometimes too strong, like when he was so gung-ho in forging Shuna a kitchen knife that it turned into an Absurdly Sharp Blade which cut the entire kitchen in half when she simply tried testing it out.
Heroic Self-Deprecation: He's quite aware of the fact that he was among the weaker onis back in their village, and he outright views himself as "nothing". But he refuses to let that hold him back, and makes sure to always give his all with smithing since it's the one thing he knows that he's good at.
Out of Focus: Due to being a blacksmith, he gets far less focus than the other oni.
Utility Party Member: When it comes to direct combat skills he's among the weakest in Tempest even after being named, with him only fighting among his fellow oni with a hammer when Rimuru first met them because they were desperate for numbers. But in terms of blacksmithing skill he has practically no equal, being capable of forging armor and weapons that not only are strong and tough enough to withstand the immense power of his allies, but in many cases outright make said allies even deadlier than they already were.
Weapons of Their Trade: He wielded a large hammer back when Rimuru first met him, trying to use his blacksmithing skills for combat. Even compared to the other oni who could barely touch Rimuru, he's so sluggish and imprecise that it's clear he only used said hammer out of desperation rather than weapon specialty.

Lizardmen/Dragonewts

Lizardmen in General

A group of humanoid lizards that were once in the same danger of being devoured by the orcs as the Kijin, until Rimuru helped them survive. Some of them, namely Gabiru and his sister, joined the city of Tempest after the events.

Lizard Folk: Lizardmen are exactly as the name says, bipedal humanoid lizards. Becoming Dragonewts has them retain said lizard-like appearance while simply adding extra features based on dragons.
Our Dragons Are Different: Evolving turns them from Lizardmen into Dragonewts, giving them the properties of dragons, including enhanced physical strength, wings for flight, and a fiery Breath Weapon.
Proud Warrior Race: At their introduction, most of the Lizardmen are too proud to even consider asking for help from outsiders in order to face the Orc Disaster, believing that their own strength and knowledge of the terrain will be more than enough. At most, they would have simply "recruited" other monsters like the goblins to serve as extra troops and cannon fodder with the Lizardmen themselves obviously in full command. When Abiru insists on fighting defensively and buying time for his alliance with Rimuru to arrive and relieve them, a majority of his troops chafe under such commands and don't require much convincing to side with Gabiru's coup and fight the Orcs out in the open. They collectively gain a measure of humility after Rimuru saves them from being wiped out.
Super Mode: After training with Middray, the Dragonewts of Tempest learn how to utilize Dragon Body, which temporarily boosts their physical and magical abilities as they gain more draconic traits. However, not only do they run the risk of going berserk if they're not careful, once the transformation wears off their bodies suffer backlash.

Gabiru

https://static.tvtropes.org/pmwiki/pub/images/ch17_body.png

Voiced by: Jun Fukushima (Japanese), Austin Tindle (English)^{Foreign VAs}

The son of the Lizardmen Tribe chieftain and the self-proclaimed hero of his nation. Incredibly arrogant and haughty, he gets his comeuppance quite rapidly, after which he follows the same Defeat Means Friendship dynamics with Tempest. In addition to maintaining control of Tempest's Dragonewt forces, he is also Vesta's chief scientific aide.

"Ass" in Ambassador: He spends his first meeting with Rimuru's village constantly insulting Rimuru for being a slime and treating his followers as if they were pathetic weaklings. It's just a few sentences in before Benimaru is asking Rimuru for permission to kill him. The ironic thing is that Gabiru was supposed to be there to ask for their help.
The Atoner: After his hubris in believing he knew what's best for the lizardmen almost got them all slaughtered by the orcs, he does the best he can to serve Rimuru as repayment for him saving them, such as supporting Vesta in potion-production or acting as one of the first-line fighter generals, and he's been humbled enough to know what he works best at.
Badass Boast: He gives a surprisingly impressive one to a church soldier.
"My name is Gabiru. There is no need for you to remember, for it shall be your memento to the Netherworld!"
Benevolent Boss: Competence aside, Gabiru is extremely loyal to his subordanence, refusing to let them get killed facing the Orc General and taking the full blame for his betrayal of his father to spare them from death.
Boisterous Weakling: Well, he's not exactly weak but more undisciplined and completely unused to actual combat against enemies that can match his strength. When he's pitted against Gobta by Rimuru he makes a big show of his attacks instead of being cautious and winds up getting caught completely off guard by Gobta knowing the "Shadow Movement" skill. He fares better against the Orc General due to realizing he can't afford to hold back anything, but even with his father's Vortex Spear he can barely stand his ground, much less actually win.
Crouching Moron, Hidden Badass: Getting his strength and abilities massively boosted after pledging loyalty to Rimuru did nothing to erase his comically boastful attitude and overall idiocy, simply making him understand reality enough to know his place, which still results in him frequently acting as comic relief from doing dumb things. Enemies would do best not to underestimate him, though, as there is a good reason why he and his Lizardmen group are part of the frontline forces for Rimuru's army, best displayed when he goes Let's Get Dangerous! and crushes several knights following a Badass Boast.
Defeat Means Friendship: Joins Rimuru after the Orc Lord is defeated and he himself is banished for his (admittedly well-intentioned) treason against the Lizardmen.
Draconic Humanoid: Is a Lizardmen and later evolves into a Dragonewt, acquiring additional draconic traits like horns, wings, and a Breath Weapon.
Dragon Ancestry: Lizardmen claim to be descended from dragons.
The Exile: Technically became this to the Lizardman tribe for his well-intentioned treachery during the Orc Disaster crisis and forbidden from returning until he proves his worth, though in practice it was more formality since his father still dearly loves him and had to punish him somehow to appease their law, with it being implied their father sent Souka to Tempest in part to keep an eye on him. He redeems himself after Rimuru awakens as a Demon Lord and he himself is promoted to an executive position within Tempest.
Face Death with Dignity:
- With the Orc General's ax bearing down on him and no time nor energy to react, instead of panicking, he simply closes his eyes and calmly awaits his inevitable end. Luckily The Cavalry shows up at that exact moment.
- When he believes his father intends to kill him for his treason, he not only fully accepts the punishment, but even considers it is only right for what he did.
A Father to His Men: He refuses to let his subordinates join him in fighting the Orc General due to the difference in power, and he's reduced to tears when they throw themselves in front of him to save him from Gelmud's magic attack. When Rimuru throws him healing potions, he scrambles as fast as he can to use them on his downed comrades, and this act of selflessness is what makes Rimuru's opinions of him become much more favorable.
Fearless Fool: About the only positive thing about Gabiru Rimuru can get from his initial impressions is that he's incredibly brave, as shown when he's the only Lizardman not cowering in fear before an angry Ranga at his full size. Combined with his ego, however, it just makes him all too willing in jumping into situations without thinking.
Foolish Sibling, Responsible Sibling: He more or less plays the Foolish Sibling to Souka's Responsible Sibling. While Gabiru was off doing whatever upon being named, and in general being way too full of himself, Souka was doing her job as the captain of the guard, keeping her father and her people safe.
Heroic BSoD: He hits his when he learns straight from Gelmud's mouth that in the end he was just an Unwitting Pawn meant to be eaten by the Orc Lord in order to fuel his ascent to Demon Lord, and it only gets worse when those amongst his admirers throw themselves in front of Gelmud's attack to save him and nearly die. He's reduced to crying by the end as Rimuru hands him healing potions that he desperately uses on his men as fast as he can.
A Hero to His Hometown: Other members of the Lizardman Tribe love this guy, mostly because of the prestige that actually having a name provides. Unfortunately, this has the side effect of stroking his ego, preventing him from really worrying about improving himself and making him seem pompous and irritating to outsiders.
Hidden Depths: Deep down he questions his own hype and does seem to genuinely want to make sure his father can retire with peace of mind. He is also surprisingly not a terrible tactician, and knows how to plan battles in such a way as to exploit the Lizardmen's advantages over the Orcs in their native terrain, though his plans fail because he went into battle without bothering to learn anything about his enemy.
Humble Pie: One of the biggest turning points for his Character Development is learning that he was a Normal Fish in a Tiny Pond, with him understanding not only that there are people out there much stronger than him, but also that it's better for him to utilize his specific strengths for the right situations, letting his allies with their own strengths deal with other scenarios, rather than believing he can do everything by himself.
Let's Get Dangerous!: While he already got more badass and capable overall after pledging loyalty to Rimuru, most of the time he still acts as boastful comic relief. However, there are times when he gets completely serious, during which he leaves out any boasting about his greatness, simply stating his name before getting straight to destroying his enemies.
Normal Fish in a Tiny Pond:
- Played straight before Rimuru's appearance, as he does have all the advantages he brags about when compared to the average Jura Forest inhabitant — who were mainly low-level monsters like goblins or kept to themselves like dryads.
- Inverted after Rimuru appeared and started his nation-building quest. Gabiru is near-worshipped by his fellow lizardmen and is special among them due to having a name and having all the benefits it provides. However, when compared to those who follow Rimuru, who takes it upon himself to give everyone under him a name and on top of being stronger than the one who gave Gabiru his, he's become a bombastic but average fish for his more powerful than usual pond.
- Played straight again following him becoming a subordinate of Rimuru, but going from the opposite direction. As part of Rimuru's forces, there are plenty of people like the kijin that are stronger than him, something he's humble enough to acknowledge. To most people outside Rimuru's army, he's got the abilities of a decently strong Dragonewt that can crack the ground with a little force and slaughter several soldiers in seconds.
Oh, Crap!: He has one when he senses the power of a large Orc and assumes it's the Orc Lord. It only gets worse when the orc reveals it's "just" an Orc General and far inferior to the true Orc Lord, and it reaches its zenith when despite giving a good fight he can't defeat it.
Power Gives You Wings: After receiving a powerboost from being renamed by Rimuru, he grows a pair of wings.
Prongs of Poseidon: He wields his father's Water Vortex Spear, initially taken during his coup to fight the orcs, and then willingly given to him shortly after his exile as a show that his father still loves him despite everything. As the name suggests, it can create and manipulate powerful water attacks.
Purple Is Powerful: After receiving his powerboost and evolution from being named by Rimuru, his green skin turns purple.
Small Name, Big Ego: A zig-zagging example. He does have an inflated sense of self-worth about being the Lizardmen Chieftain's son and possessing a name, but there are multiple points where he honestly questions if he's hyping himself up too much or that he's not good enough. His lizardmen comrades, on the other hand, are all too willing to stroke his ego to keep him going even further and burying his doubts.
Smarter Than You Look: He's a braggart and a fighter, but it's easy to forget that Gabiru was assigned as Vesta's assistant before he received a proper promotion to Tempest officer, remains Vesta's chief science aide in regards to plant studies, and actually has a decent working knowledge of magical and scientific theory and application. Even a side comic in the manga reveals that he knew what autotomy is, and how it is related to lizardmen.
Took a Level in Badass: Accidentally gets named by Rimuru who states out loud that his current name is fine, granting him wings and a major boost in power. He also takes his Humble Pie with great seriousness, re-evaluating his abilities and working towards getting stronger and more skilled to serve Rimuru better. Believe it or not, he eventually becomes one of the 12 entities serving under Rimuru considered strong enough to be individual Demon Lords. This gets so extreme that, during Tempest’s initial confrontation against the Empire’s forces, the leader of the Imperial Air Division, upon seeing Gabiru’s power, mistakes him for none other than Veldora himself.
Unwitting Pawn: Gelmud plays on his ego and desire to protect his people to make him overthrow his father and take control of the Lizardmen, relying on Gabiru's lack of knowledge about the Orc Lord's abilities to make him commit to a direct assault against the Orcs and get them wiped out to feed the Orc Lord's strength.
"Well Done, Son" Guy: The light novels say his secret motivation is to gain his father's approval, even when overthrowing him. This trait eventually gets carried over when he is exiled to Tempest, wishing to gain Rimuru's approval.
Well-Intentioned Extremist: His desire to protect his people from the Orcs drives him to betray his father and chieftain to seize power over the Lizardmen, which in and of itself is a ploy by the demon Gelmud and his comrades to slaughter the Lizardmen.
Winds of Destiny, Change!: Gabiru's Unique Skill [Braggart] has the Sub-Skill "Change Destiny", which allows him once a day change any outcome for himself to his own favor, allowing him to even rewrite a fatal wound into never happening. Once his Skill evolves, "Change Destiny" becomes "Alter Destiny", which while keeping the "once a day" limit, now allows him to affect others as well, ally or enemy, and the Skill can be used as many times as he wants per day since the limit is now "once a day per person".

Gabiru's Group (Kakushin, Sukero, Yashichi)

https://static.tvtropes.org/pmwiki/pub/images/lizardmen_trio.png

Left to right: Kakushin, Yashichi, and Sukero

Kakushin is voiced by: Hiromichi Tezuka (Japanese), Patric Carrol (English)^{Foreign VAs}

Sukero is voiced by: Yoshihito Sasaki (Japanese), Garret Storms (English)^{Foreign VAs}

Yashichi is voiced by: Akinori Egoshi (Japanese), Ricco Fajardo (English)^{Foreign VAs}

A group of Lizardmen who are fantastically devoted to Gabiru, and who answer to his beck and call.

Nice Job Breaking It, Hero: Their hero worship of Gabiru prompts him to stage a coup against his father in an attempt to fend off the invading orcs. This backfires spectacularly, as they find themselves outmatched against the orcs, and his father's pleas to ally with Rimuru proves to be the correct decision.
No Hero to His Valet: While the group is normally all about hyping Gabiru's talent and abilities, they're actually fully conscious of his faults and willing to point out when he starts lying to himself, such as drunkenly fabricating memories of a close sibling relationship with Souka when they were kids, to which they note that the siblings were actually just as distant-but-loving back then as they are now.
Satellite Character: An entire group of them for Gabiru.
Taking the Bullet: When Gelmud attempts to murder Gabiru, they willingly throw themselves in front of his attack to save their idol. They would have most likely died had Rimuru not given Gabiru some healing potions to save them.
Undying Loyalty: To Gabiru. When he's practically exiled from the clan, they meet with him and reveal they've volunteered to join him in exile to be with him.

Souka

Voiced by: Rumi Ōkubo (Japanese), Caitlin Glass (English)^{Foreign VAs}

The younger sister of Gabiru, and the former captain of the guard. She left her clan in order to join Tempest so she could further enhance her skills, an order given by her father.

Action Girl: She's the captain of the guard for a reason. This becomes especially more prominent after being named.
Aw, Look! They Really Do Love Each Other: One-sided, as Gabiru clearly loves her but Souka spends far more time being exasperated by her brother's eccentrics. Still, their bond is mutual as without it Souka never would have evolved due to her brother becoming an Awakened Demon Lord, and later during the battle with the Empire's Magical Beast Division she was fully willing to jump in and fight alongside her brother against one of the Division's top generals despite being outclassed.
Bishōnen Line: Sure, every monster goes through this after being named, but it's notable with Souka and her aides because they go from clearly lizardlike humanoids, to essentially humans with draconic wings, horns, and notable fangs. The change is even more notable when compared to Gabiru and his men, who merely gain a power boost and wings.
Cute Little Fangs: These, alongside her draconic traits, are the only things separating her from humans after being named.
Cute Monster Girl: Even before evolving from being named, Souka had a notably softer look compared to the rest of the lizardmen.
Daddy's Girl: It's subtle, but Souka seems to hold a great affection for her father: She stayed by his side during the Orc trouble, she's the one to help him stand up after rescuing him after Gabiru's betrayal, and she's goes to Tempest on his orders.
The Dutiful Son: She acted as this during her time as the captain of the guard, helping protect the temple.
Hidden Depths: As proven during the Founding Festival, Souka has a gift for working a crowd, serving as the MC for the battle arena tournament and the announcer over the first foray into the Labyrinth. She also shows she can ham it up as well as her brother when prompted.
Ninja: As a member of Souei's Shadow Squad, she dresses like a stereotypical anime ninja and practices the same stereotypical anime ninja tropes that Souei does.
Number Two: She becomes Souei's second-in-command of the Shadow Squad.
Reluctant Fanservice Girl: Notably during "The Slime Diaries" Beach Episode, despite wearing the most conservative swimsuit between herself, Shion and Shuna, Souka still feels the need at first to try and cover more of her body with her wings.
Ship Tease: While Souka’s crush on Souei isn’t touched on much in the main series, there’s at least one of these moments within every episode of “Slime Diaries” spinoff series, in which Souka more often than not comes across as a love struck maiden rather than a loyal subordinate.
Subordinate Excuse: She has an obvious crush, especially in “Slime Diaries”, on her teacher and superior Souei.
Winged Humanoid: Once she becomes a Dragonewt, she resembles a human woman — though she can sprout draconic traits like horns, wings, and a tail at will.

Souka's Squad (Touka, Saika, Nansou, and Hokusou)

https://static.tvtropes.org/pmwiki/pub/images/dragonewt_squad.png

Left to right: Touka, Saika, Souka, Nansou, and Hokusou

Touka is voiced by: Yū Sasahara (Japanese), Dani Chambers (English)

Saika is voiced by: Ayaka Shimizu (Japanese), Molly Searcy (English)

Nansou is voiced by: Shogo Sakata (Japanese), Anthony DiMascio (English)

Hokusou is voiced by: Daichi Hayashi (Japanese), Aaron Campbell (English)

A group of Lizardmen that accompanied Souka when she entered Tempest. They were named by Rimuru and now form the Shadow Squad, along with Souka and Souei, who act as their leaders.

The Apprentice: Along with Souka, they're fledgling ninjas being taught by Souei in the art of ninjutsu.
Bishōnen Line: Just like Souka, these four Lizardmen took on practically near-human appearances after evolving into Dragonewts, unlike Gabiru and his group whom all stayed lizard-like while gaining draconic qualities.
Gender-Equal Ensemble: There are two men and two women among them, which still applies if Souka and Souei are counted.
Ninja: They're Souei's covert task force.
Satellite Character: Just like Gabiru's group mainly exists as an extension of him, Souka's squad mainly acts as extra muscle under her and Souei's command, along with being people to converse with about her crush on Souei and how she feels about Gabiru as her brother, with little individual character outside that.
Theme Naming: The girls' names end in "ka" (flower) and the guys' names end in "sou" (spear). The prefixes, on the other hand, refer to the four cardinal directions.
Winged Humanoid: Same deal as Souka. The light novels and subsequent materials indicate this was because they believed during their evolution a more human appearance would better serve them in their new duties to Tempest.

Abiru

Voiced by: Tomoyuki Shimura (Japanese), Christopher Sabat (English)

Gabiru and Souka's father, and the chieftain of the Lizardman tribe inhabiting Lake Siss.

Fountain of Youth: After Rimuru names him, Abiru regains a more youthful appearance.
I Want Grandkids: The Slime Diaries has Abiru attempt to set up Souka for marriage interviews, only for his daughter to turn down every single one of them in annoyance.
Jaw Drop: His reaction to Souei effortlessly restraining and butchering an invading Orc warrior.
Souka: One can't help but react that way, it seems...
Reasonable Authority Figure: When Souei shows up on behalf of Rimuru to offer an alliance between Tempest and the Lizardmen in order to deal with the Orc Disaster, Abiru does his best to prevent hostilities from rising between both sides and agrees to meet with Rimuru to discuss it. Unlike most of the Lizardmen, Abiru is all too aware that the Orc Disaster is not something his people can handle on their own.
Tough Love: Exiles Gabiru for his rebellion, but allows him to keep the Water Vortex Spear, indirectly letting him know that he still loves his son.

Orcs

Orcs in General

A race of boar-like humanoids who were once controlled by the Orc Disaster. They were actually a tribe of Orcs who were suffering through a great famine, and most of them were brainwashed by the effects of Starved into trying to devour everything and everyone to satiate their hunger. Once everything is cleared up and the effects of Starved are gone, the Orcs become part of Tempest's workforce.

Always Chaotic Evil: Initially come off this way during their invasion of Jura Forest, what with their monstrous Horror Hunger, their creepy Crowd Chant (that almost makes them seem like they Speak in Unison), and the fact that they're explicitly stated to have low intelligence and be prone to violence. Geld's backstory gives a hint that something more complex is going on, and then it gets fully subverted once Rimuru defeats them. Following this, they lose their Faceless Goons appearance, and are portrayed with the same variety as the other races, even featuring women and children.
Cannibalism Superpower: Under the influence of Starved, they could assimilate traits from other monsters they devoured — like obtaining scales and webbed toes from eating Lizardmen.
Death of a Child: Even the children who weren't lucky enough to get food for the famine wound up hitting the dirt bed.
Heel–Face Turn: Once the effects of Starved are over and they're allowed to live in Tempest, they swear loyalty to Rimuru and become the main construction force of the city.
My God, What Have I Done?: The Orcs were horrified at what they'd done once the effects of Starved wore off. It was only Rimuru offering to "eat" their sins that managed to snap them out of it.
Pig Man: They are boar-like humanoids.
Shockwave Stomp: After coming under Rimuru's service and being named, all of them gained the ability to create devastating tremors just by slamming one foot heavily onto the ground. While one doing so only really throws an enemy off-balance, several stomping in unison while surrounding an area both debilitates foes and opens massive pitfalls to trap any who cannot fly or jump high enough, leaving those forced to climb out as easy to slaughter.
Villainous Glutton: Back when they were under the effects of Starved, they would devour anything and anyone they came across, including their own dead, to become more powerful.

Geld II

https://static.tvtropes.org/pmwiki/pub/images/geld.png

Voiced by: Taro Yamaguchi (Japanese), Cris George (English)^{Foreign VAs}

The son and former right hand to the Orc King, who then became an Orc Disaster to try and prevent a famine. He was one of the survivors of the attack against the Starved Orcs, and was later named by Rimuru to carry the legacy of the good king which he does by heading Tempest's construction efforts.

The Atoner: He desperately wants to make up for the transgressions of the Orcs, even knowing it was a Deal with the Devil situation with no good ways to end.
Bad Powers, Good People: As an Orc Lord, he obtains skills such as Corrosion and even wields a shield made out of Charybdis' scales. However, he is one of the gentlest persons in Tempest.
Beware the Nice Ones: In his down time, he's a Gentle Giant and Friend to All Children. When called to war, and especially when pissed off, he shows why he's the successor to the name of Orc Lord and Orc Disaster.
Close to Home: Killing your allies, especially for the sake of power, is a good way to get on his bad side since it reminds him too much of what his people did under the effects of Starved. Eating your allies in order to gain said power makes him even angrier, especially due to what Starved made his people do. When Shogou murders Kirihara, followed by eating her flesh in the light novel, to gain the [Survivor] skill, Geld forgoes a clean kill in favor of giving him a No-Holds-Barred Beatdown and then letting his new Healing Factor kick in to prolong his suffering.
Clueless Chick-Magnet: He doesn't really realize it thanks to his Workaholic mindset and general busy time around Tempest, but Rimuru notes Geld actually has a lot of admirers (orc and otherwise) for his strength, his muscled build, his stoic nature, and his Hidden Depths. Rimuru even muses he could easily land a date if he actually bothered to try.
Combat Pragmatist: He bluntly tells Shogou when the latter tries to call him a coward for wearing armor that when in war, fighting with any advantage you can get is the only proper way of showing courtesy to your opponent, since it shows you're taking the fight and victory seriously.
Everyone Has Standards: While he didn't have a very high opinion of Shogou during their fight to start with, seeing him willingly murder his comrade Kirihara for a power boost and healing tanks any sort of respect he might have had for him even as a warrior.
Faster Than You Look: He prefers a Stone Wall strategy, but after reaching the limits of his patience with Shogou after watching him kill Kirihara, he engages the boastful Otherworlder in hand-to-hand combat and easily dodges his first strike before suddenly smashing him into the ground and delivering a No-Holds-Barred Beatdown.
Friend to All Children: While he tries to deny it as being something he likes, he has a strong connection towards children, with any time spent resting being time where tiny goblinlings climb all over him in a playful and happy manner. That's not even getting into his subtle and secret feelings about wanting to make sure all children can grow up happy and well-fed, not just due to the trauma of how many orc children starved or even died due to the famine his people experienced, but also because their happiness makes him feel his work-efforts are making a change for good.
Gentle Giant: He's a pretty big guy in both size and weight compared to most other characters, and his largeness can have an intimidating feel to it, but he's actually a rather gentle and mellow guy who gives his all for perpetuating everybody's peace and happiness through his work, along with being nice to most people, especially children. That said, while he may be gentle normally, when he needs to get serious and fight, he shows quite well that his size isn't simply fat, but a mass of strong muscle that is very capable of pulverizing enemies to a pulp.
Good Is Not Soft: While his strong case of being an atoning Workaholic can make him look stern and stoic, overall he's very much a Gentle Giant, getting along well with others, especially children. That said, this general kindness does nothing to prevent him from being very capable of fighting people to the death, and maintains a Combat Pragmatist mentality about ending "fights" as quickly and efficiently as possible, with anything like honor having no place in a warzone. He avoids being soft for the express purpose of making certain that he can maintain Rimuru's desire for peace so that he has a place where he can show his kindness.
Hidden Depths: He looks like a guy who's only good at heavy-lifting and fighting, but The Slime Diaries shows that he's quite capable of doing gentler and more finely-detailed work, such as replanting and sprucing up some small flowers, or delicately folding and marking a piece of paper to make an orc face. He actually gets rather embarrassed when people notice his gentler efforts.
I Am Not Left-Handed: As shown by his fight with Shogou, his regular fighting style is to act as a Stone Wall, tanking attacks in order to trick enemies into getting afflicted with his Corrosion skill, and quickly exploiting the paralysis to split their skull with his cleaver and end their suffering. But when his opponent shows that they don't deserve such mercy, he puts away the cleaver and switches to a Good Old Fisticuffs Lightning Bruiser style, pummeling the enemy rapidly and repeatedly while applying Corrosion, for the deliberate sake of dragging out their pain and agony in order to express how serious and furious he is, before eventually killing them.
Irony: Geld knew full well where the battle against Clayman's forces would take place, at the ruined area of the old Orc kingdom Orbic. The place where they fell to Clayman's plotting would be the place where Clayman's own army fell. More irony is tacked on in that the High Orcs that now served Rimuru knew the enviroment better than Clayman's forces knew it themselves, so Clayman's schemes gave Rimuru the perfect weapon to use against his own forces.
Legacy Character: Named after the very Orc Disaster he once served, so that he could honor his father's legacy.
Machete Mayhem: He wields a large cleaver much like his father did into battle.
Make Them Rot: He has his father's [Corrosion]/[Rot] skill, which allows him to manifest demonic snake-like creatures that bite his opponents and forcibly rot their flesh.
Parental Substitute: While he's always been a Friend to All Children, in The Slime Diaries he's shown to be around a little ponytailed Goblin girl at least Once per Episode having father-daughter bonding moments with her, to the point the latter half of Season 1 shows her wearing a scarf made in image of his own and the two of them trading gifts in the Christmas episode.
Stone Wall: Geld marches into battle with a shield and covered in armor. When he doesn't have a weapon, he relies on his Corrosion to wear the enemy down. However, it's shown when sufficiently pissed off, he turns into a Lightning Bruiser who moves much faster than someone of his bulk and armor should.
Stout Strength: As an orc he has a naturally stocky body, and once his people acquire a consistent supply of good food he builds up a decent level of belly fat. But as already implied by his beefy arms, underneath that fat is a mass of solid muscle that provides him enough strength to create ground craters and air shockwaves with every punch. When he gets really serious he's also an Acrofatic, moving speedily and gracefully despite his fatty exterior.
Superior Successor: To his father, as Geld not only successfully leads the orcs to a better life as his father wanted to, he also surpasses him in power by accepting Rimuru's offer to rise to the level of a True Demon Lord.
Workaholic: In his desire to atone for what his people did under the influence of [Starved], he's near-constantly working on various construction and heavy-lifting projects for the sake of Rimuru's vision for a world where nobody would experience the tragedy the orcs did, often working past his limits due to thinking he can never do enough to repay Rimuru's kindness. He actually admits to Rimuru that, unlike him who can find happiness in working, Geld can derive no joy from it since he buries himself in working to distract himself from his worries.

Humans

Gard Mjöllmile

https://static.tvtropes.org/pmwiki/pub/images/garde_myourmiles.png

Voiced by: Yutaka Aoyama (Japanese), Kenny Green (English)^{Foreign VAs}

A well-respected merchant formerly of the Kingdom of Blumund, Mjöllmile is a shrewd man in matters of business but also possesses a good heart beneath his desire for coin. Having been saved by Rimuru in their first meeting from a dragon attack, a grateful (and somewhat smitten) Mjöllmile quickly struck up a partnership and friendship with the slime, eventually moving to Tempest full-time and becoming their Minister of Finances and Public Relations upon Rimuru's request.

The Alcoholic: He loves his booze, though he doesn't let it get in the way of his job. He originally thanked Rimuru for saving his life by inviting him to a whole drinking session at a bar on his tab. Rimuru approved.
A Day in the Limelight: He's a focus character in Volume 17 of the light novel, which focuses away from the main narrative to follow four different side characters of varying importance.
Establishing Character Moment: In the manga, his comes when his caravan is attacked by a dragon, spilling the valuable Full Restore Potions of Tempest everywhere. As Mjöllmile tries to gather them up, he notices a crying child and her horribly wounded mother nearby, and doesn't hesitate to use one to save the latter. He then urges them to run while the dragon sets its sights on him, fully ready and willing to die if not for Rimuru's arrival.
Everyone Has Standards: He's not opposed to dealing under the table or slipping bribes, but when a potential client comes to him with an offer that stinks of the slave trade, Mjöllmile swears it off for pragmatic, legal, and personal moral reasons and even lets slip some of this info to authorities to check out and bust it.
Face of a Thug: He is not exactly pleasing on the eye, and some people are initially suspicious of him (like the trinity in "Trinity of Tempest") but overall he is a fairly nice and generous man, for a crime lord.
Jerk with a Heart of Gold: He can be vulgar and daredevil-like, but he's a virtuous man who knows how to get people to relax and have fun and he never attempts to cheat Rimuru out of anything. He's even willing to risk his own reputation in order to ensure Tempest's name will be held in the clear.
Stupid Sexy Flanders: He was smitten with Rimuru when he first met him, mentally calling him a "goddess". Granted, Rimuru was using an older adult form at the time for a disguise, but Mjöllmile's feelings weren't hurt by the truth. He even keeps a portrait of Rimuru in his office.

Honjou Masayuki

Lightspeed Masayuki

A stray Otherworlder who arrived in the world by sheer chance, Masayuki is granted the Unique Skill: Chosen One, marking him out as a hero to the masses. Masayuki, however, is little more than an otaku with almost no combat ability of his own. Yet, through almost no effort of his own, he found his heroic reputation snowballing completely out of control, resulting in him nearly coming into conflict with Rimuru against his will. After participating in the Founding Festival’s Tournament, Masayuki not only concedes victory to Gobta (who’d knocked himself out with a missed attack), but joins Tempest, essentially becoming one of Rimuru’s subordinates. Masayuki happily works with Rimuru, Veldora, Ramiris, and Mjöllmile to further fine-tune Tempest’s Labyrinth and acts as its chief promoter by working his way down through it with his party.

Being Good Sucks: For a given definition of Good, anyway. Because he’s designated a hero and the de-facto good guy, Masayuki repeatedly finds himself dragged into conflicts and situations he’d rather avoid. This comes to a head when, after taking down a criminal syndicate that had been engaging in human trafficing and rescuing several elves, Masayuki finds himself dragged to Jura to reunite the elves with their own people, where his party nearly force him into battle with Rimuru. Because Rimuru is a Demon Lord, his party members basically decide that this automatically makes Rimuru the “Bad Guy”, with Masayuki as the designated “Good Guy” needing to defeat him to save the world, despite neither Masayuki nor Rimuru wanting to fight each other.
But Not Too Foreign: It's noted he has Russian heritage, which gives his looks a unique spin that makes him stand out as attractive, and he dyes his hair blonde as well which helps with this.
Charm Person: Inadvertedly thanks to how Chosen One's effects work to make people see him in the best possible light. The only ones reliably immune to it are those with Ultimate Skills, sufficient willpower that they have the potential to develop such skills or have some form of mental interference resistance, or the undead.
The Chosen One: Literally the name of his Unique Skill, and thanks to his reputation everyone assumes he really is this.
Fake Ultimate Hero: Despite an impressive resume of accomplishments, Masayuki wisely considers himself this, as he owes every ounce of his success to his Unique Skill, which always makes things work out in his favor.
Flunky Boss: Against his will. The members of Masayuki’s party do most of the fighting, largely because Masayuki doesn’t actually want to. Thanks to his Unique Skill, even relative weaklings in his group become nigh unstoppable powerhouses.
I Just Want to Be Normal: Oh, does he ever. Unfortunately for him, fate has decided otherwise, so he needs to suck it up and do the best he can.
Plague of Good Fortune: Masayuki’s Unique Skill, Chosen One, is this trope incarnated. Even though Masayuki has virtually no combat ability on his own, this skill will ensure that every attack he makes will be an automatic critical hit. On top of that, it ensures that, no matter what the situation, things will work out to portray Masayuki in a positive light no matter what the leaps in Insane Troll Logic, ensuring that his heroic reputation will continue to grow…whether he likes it or not. On top of that, the benefits of this skill are extended to everyone in his party, with no apparent limit to the number of people affected. Thanks to this, by joining up with Masayuki, even relative mooks wind up becoming a Badass Army. Of course, this just makes things worse for Masayuki.
Reincarnation: He's actually the reincarnation of Emperor Rudra of the Eastern Empire, who looks like an older Masayuki, or at the very least an incomplete reincarnation as some of Rudra's soul fragments are still within his old body acting as a Restraining Bolt on Justice King Michael's influence. True Dragon Velgrynd recognizes this and revealing this revelation is what leads to what's left of the Empire after the war with Tempest rallying under him to make peace.
Reincarnation Romance: True Dragon Velgrynd is in love with him because he's a reincarnation of Rudra, the hero she's always loved. Mayasuki isn't necessarily opposed to being with her, though he does still find her intimidating.
Super Power Lottery: Chosen One pretty much always ensures that Masayuki will come out on top, no matter the situation. If he lands a hit, it will automatically be a devastating one. If an opponent is too strong for him to actually defeat, despite that, he will wind up inadvertently Talking the Monster to Death. By joining his party, a group of mooks will find themselves transformed into actual badasses. And everyone seeing him at work will believe that all of this happens because Masayuki is just that awesome. Granted, it has no effect on anyone with an Ultimate Skill, so it isn't the big winner by far, but among Unique Skills it has the distinction of being grouped among the few already on par with such skills despite still being technically inferior. Then it actually does evolve into the Ultimate Skill King of Heroes.
Winds of Destiny, Change!: Chosen One ensures that, no matter what happens, things will work out to Masayuki’s benefit, and everyone will be influenced to view Masayuki more favorably as a result.

Primordial Demons

Primordials in General

The four primordial demons that come to serve under Rimuru out of respect for his strength. Diablo came to his call during his Harvest Festival to become a Demon Lord, while Ultima, Testarossa, and Carrera were recruited by Diablo in order to make his personal work easier.

Blood Knight: While their exact attitude towards it varies from demon-to-demon, all four absolutely love fighting.
Color-Coded Characters: Each one of them is associated with the color of their hair: black for Diablo, white for Testarossa, purple for Ultima, and yellow for Carrera.
Colourful Theme Naming: Prior to being named by Rimuru, they only had their signature colors to go by for names: Noir/Black for Diablo, Violet/Purple for Ultima, Blanc/White for Testarossa, and Jaune/Yellow for Carrera.
The Dreaded: Every last one of them is famously feared, for good reason. For more specific examples:
- Diablo is the most feared besides his old rival Guy Crimson, precisely because he was Guy's oldest rival and there was very little information on him otherwise.
- Ultima has been in the sights of the Holy Church simply for existing in their territory. The empire soldiers that were fighting Testarossa barely held hope until Ultima stepped in, then despair was all they knew.
- Testarossa caused the "Lake Shore Dyed Scarlet Incident" and made the entire Eastern Empire perpetually on high alert if there is even a possibility of her being present.
- Carrera casually fired Nuclear Magic at Leon Cromwell's terrirory just to test him. This, of course, made him really annoyed and scared his people tirelessly.
Monster Progenitor: They are four of the 7 original progenitor demons. As such, their age and power let them bypass most of the restrictions demons have when they incarnate physically on earth.
Mook Horror Show: When these demons are given free reign to cut loose, they inflict this like an art form on their foes as they casually No-Sell their best efforts while effortlessly tearing through them.
Religious and Mythological Theme Naming: They all develop Ultimate Skills named after a Fallen Angel: Diablo - Azazel, Testarossa - Belial, Ultima - Samael, and Carrera - Abaddon. It fits with Guy Crimson's being named after Archangel Lucifer.
The Rival: Testarossa, Ultima, and Carrera were this to each other back during their time as nameless Primordials, always acting as a balancing force to keep any one from getting too strong over the other. When they come to Tempest and pledge their ernest loyalty to Rimuru, it then turns into a rivalry between themselves (and Diablo) over who should become his most favored subordinate.
Strong and Skilled: What makes the Primordials so dangerous; not only are they physically and magically among the strongest of their kind, as the oldest demons they have the most extensive battle experience and instinct honed in constant conflict. Tens of thousands of years have passed and yet the number of times they can claim to have truly lost to anyone other than a fellow Primordial can likely be counted on one hand. Among the Primordials though some do slip further into Unskilled, but Strong or Weak, but Skilled territory compared to their fellows.
Stronger with Age: Demonic spirits overall follow the idea of getting stronger the longer they live (once hitting the "cap" in magical capacity, turning towards gathering experience and knowledge of how to best use that power), and as all four are Primordial demons that are on par with Guy Crimson in terms of how long they've lived (easily over 10,000 years by measuring against the oldest known subordinate demon Moss), they are also among the strongest beings in the world.
Vehicular Theme Naming: Rimuru named Diablo such both because it literally means "devil" and because it was the name of a sports car (specifically a Lamborghini Diablo). All following primordials were given sports car names as a deliberate theme: Ultima from the Ultima GTR, Testarossa from the Ferrari Testarossa, and Carrera from the Porsche Carrera.
Willfully Weak: All of them can forcibly restrict their power to such a degree that it makes them seem much weaker than they really are. Diablo can pass himself off as a mere Greater Demon in power, while the other three can flat-out erase any trace of their presence and appear as simple humans.
The Worf Effect: Ultima, Carrera, and Testarossa find themselves on the receiving end of this during the War with the Empire when they go up against Velgrynd, as even together they can barely break even with the True Dragon. Rimuru fixes this when he returns to the battlefield and finally completes their evolutions, allowing them to ascend to the level of True Demon Lords.

Diablo

Primordial Noir

Voiced by: Takahiro Sakurai (Japanese), Daman Mills (English)^{Foreign VAs}

An ancient and powerful Archdemon known as the Black Progenitor, who was summoned by Rimuru during his ascension to True Demon Lord. Named Diablo, he evolved into a Demon Peer and worships Rimuru as a god, ultimately taking the role of secondary secretary.

Adaptation Dye-Job: In the original web novel he has solid red hair, but in the light novel and subsequent adaptations he has black hair with red and yellow streaks.
Affably Evil: Evil is a bit of a stretch, but Diablo is unfailingly polite and curteous, even to those who have earned his ire. Even the Luminaries that he faced were not mocked, and the only discourtesy he delivered was not telling them the details of how they were going to die.
Almighty Janitor: One of the most powerful, if not top contender for the strongest, subordinate of Rimuru, and he holds the position of second secretary despite having shown himself to be perfectly capable of taking many other duties. He refuses because he doesn't want to take any job that would require him to leave Rimuru's side as much as possible. In fact, he made the Black Numbers and recruited the other three Primordials because he didn't want to be shoehorned into another job.
The Archmage: Diablo's knowledge of magic is practically unmatched throughout the world thanks to his sheer age, unpredictable nature and odd sense of curiosity. Even when compared to his fellow Primordials he stands as the most proficient with magic, and he has the raw power to make full use of it when he's actually motivated. He can even use Holy magic (something that's otherwise anathema to most demons) to a degree that surpasses all but the strongest practioners, and possessed the unerving power to create a false world, and consign those he traps in it to non-existance. His Red Baron once he reaches his final evolution and takes his place as one of the Twelve Guardian Lords is even "Magic Lord". Special mention goes to his Multi-Stage Disintegration, a seven-fold version of the spell that he can silently cast. Guy Crimson admits that it could one-shot him if it actually hit him.
An Arm and a Leg: He lost an arm when he tried to slash through Shizu's anti-demon mask, though she noted he was holding back.
Asskicking Leads to Leadership: He recruited and became the leader of the Black Numbers by heading back to the underworld, hunting down the strongest demons he could find there, and then kicking their asses hard and long enough to get them to follow him back to Rimuru. The only exceptions were the other three Primordials, who were intrigued enough at Diablo's insistence to want to see Rimuru themselves without fighting themselves, though they only agreed to even that much after Diablo beat up their strongest subordinates.
Battle Butler: He is employed as a butler and leads the Black Numbers — a corps of demon butlers and maids.
Birds of a Feather: He and Adalman get along remarkably well, being both powerful and versitile mages who worship Rimuru more than any other, sans Shion who shares their reverance.
Black Eyes of Crazy: His bloodthirsty demonic nature is highlighted by eyes, which have black sclera with red markings and yellow irises.
Blood Knight: His love of elegance and gracefulness aside, Diablo really likes fighting, and before being summoned and named by Rimuru he was often bored out of his mind by the fact he rarely got to face off against opponents worth his time. Part of the reason he answered Rimuru's summonings was specifically because Rimuru is strong, surrounded by powerful subordinates, and often fights powerful foes. He also likes to draw out fights to see if his opponents have anything interesting to show him. This is usually not good for his opponents mental state, as they are quickly becoming aware of how outclassed they are. His 'fight' with Saare has the later an emotionally broken mess near the end of it.
Charm Person: While his sheer power was already quite good at drawing others to desire serving him, becoming Rimuru's subordinate granted him the Unique skill "Tempter", utilizing the sub-skills Thought Domination, Charm, and Solicitation to completely bend the minds, bodies, and very souls of its targets under his will, turning them into blindly loyal servants. While he can't outright Mind Control them, they'll still be subconsciously following his orders, and if they act out of line he'll be instantly aware and can command them to die almost as quickly if he wills it.
Creepy Good: He has one of the most stereotypically Red and Black and Evil All Over appearances possible for a demon, and his Blood Knight mentality means he can get rather terrifying when having "fun", but all the same he's a bizarrely moral demon who not only keeps the letter of his word but also the spirit of it, along with being willing to help people in need when they desperately ask him, such as when Tiss was about to be killed by a Phantom and she demon summoned as a last resort, with Diablo letting her keep her soul on the simple condition of keeping his appearance a secret.
Curb-Stomp Battle: Pretty much every fight he has participated in thus far sans the fight with Shizu, which he didn't take seriously since she wasn't his target and he had no interest in killing her especially once he saw her anti-demon mask ends with him utterly destroying his opponent.
- He treats his fight with Razen, The Archmage of the Kingdom of Falmuth further boosted by using the body of the Otherworlder Shogou, like a mildly amusing workout at best.
- Despite his opponent being a named demon of the same rank as him, Orthos gets utterly crushed by him, to the point he can never revive.
- The Phantom in one of the OVAs has even less of a chance, since Diablo didn't have the time to play with him.
- Poor Saare started his engagement with Diablo in blissful ignorance, but as the fight dragged on, he quickly found out that Diablo was on a level that is purely the stuff of legends (or nightmares) and the only reason he is alive is because Diablo wanted him alive for political reasons.
- Even in "Trinity of Tempest" the demonic bioweapon was Killed Offscreen in a manner that left its severed head in a way that showed that it stood no chance at all.
- The Luminaries he confronted were done in in the most horrifying way imaginable by Diablo. These poor fools managed to hit his Berserk Button at full strength, so he didn't even bother playing with them.
- Rain shouldn't have goaded Diablo into fighting her, since she only survived because of her unique skill and that Diablo felt the massive pummling she got as a lesson learned.
Dark Is Not Evil: His status as the Black Progenitor means his very existence is associated with both the color black and darkness as a whole, possessing an appearance that just screams Red and Black and Evil All Over, and the ways his powers manifest is through blatantly dark and evil-looking forms like stereotypical demon wings or long Wolverine Claws. Same goes for his descendants, who possess both the darkest color schemes out of all demons and more demonic-looking powers. Despite all of this, not only is Diablo a major case of a Noble Demon who evolves into being Creepy Good under Rimuru, but every one of his descendants have the highest levels of morality and personal standards out of all demonkind.
Deal with the Devil: What he would do to pass the time while bored before being summoned by Rimuru. In exchange for his summoner's soul, he would destroy their enemies utterly.
Debt Detester: Shizu had passed away at this point, but Noir still looked for opportunities to repay a dept to her even after that. When her replacement did a desparate summon to save Shizu's students, he offered his services for what most would call a pittance (conceal his involvement) and brutally slaughtered the phantom that was endangering them. This was decades after Shizu and the unnamed Diablo parted ways.
Demon Lords and Archdevils: He was originally a nameless Archdemon, before evolving into a Demon Peer upon being named and eventually becoming a Devil Lord. He also holds the title of Demon Lord thanks to Rimuru upgrading him.
A Dog Named "Perro": As noted by Rimuru himself, he's a demon effectively named "demon", though Rimuru did put a decent amount of thought into it by making it both in Latin/Spanish and also having it shared with a sports car.
Domain Holder: A variation. He has the means to create an illusionary world that he can make real, and that he controls all the rules within. The only way to escape it without his consent is to have more willpower and a stronger spiritual essence than him, which is nearly impossible for all but the strongest beings in the world. Anything inside of it when he dismisses it is lost from the world, including the three members of the Seven Luminaries that managed to piss him off.
The Dreaded: Anyone who knows what he really is understandably view him as this. Those that do not quickly learn to see him this way.
Even Evil Has Standards: Diablo was disgusted with Shion's work from when she was interogating the Falmuth prisoners, even questioning how it was possible.
Diablo: What in the world did she use to make this biology defying abomination?
Everyone Calls Him "Barkeep": Before he was named, he was simply referred to by others by his signature color — Noir/Kuro/Black.
Expy: Rimuru making him a butler was a nod to Sebastian Michaelis from Black Butler.
Evil Laugh: Once Rimuru gave him permission to wipe out three members of the Seven Luminaries, Diablo laughed a truly wicked one in the novel.
Fate Worse than Death: If you piss him off, but he doesn't have permission to kill you, he will make sure you know.
Flash Step: His perfered method of movement. Diablo is absurdly fast by demon standards, so much so that no one else has pull the flash step off so casually.
Formal Characters Use Keigo: He dresses like a butler, acts very sophisticated, and always speaks in keigo in the original Japanese.
Hunter of His Own Kind: In the past, Diablo was summoned by one of the members of a team of heroes called the Silver Knights in order to avenge them. Their killer was the archdemon Orthos, who was powerful enough to defeat Shizu — albeit only after she was weakened by a duel with Kuro. After mopping up the lesser demons serving Orthos, the Black Progenitor rescued Shizu and utterly destroyed Orthos with ease — despite technically being of the same rank as Orthos, without a name of his own, and missing an arm.
It Amused Me: According to other demons, Noir/Diablo is quite whimsical and doesn't have an active interest in getting stronger, instead preferring to amuse himself, especially when it comes to his Blood Knight nature (which would be difficult if he got too strong). As such, he often searches the world for new and exciting things to sate his curiosity and interest. The members of his lineage share this trait as seen with Beretta.
Killing Intent: By using [Demon Lord's Ambition] after his evolution to Demon Peer, Diablo can exert his magical power on his surroundings so intensely that the Weak-Willed are left unconscious or screaming for mercy at the wave of terror going through them.
Leitmotif: 謎, or 'Mystery' if you favor a translation. A beautiful, if haunting melody of simple, yet elegant clasical insruments, suplimented by ominous singing/chanting to further define that he is way beyond the league of nearly every demon the world has ever known, while showing his love of elegance.
Manipulative Bastard: Make no mistake, Diablo is a master of playing people into his hands. His takeover of Falmuth through civil war was Rimuru's idea, as was manipulating the nobles, but the execution was all Diablo. He basically gave them two scenarios, pay repirations or keep fighting, but the greed of the nobles would mean only real outcome was civil war, with the illusion of choice so perfectly executed that no-one would be suspicious.
Rimuru: This guy's an authentic demon. He really has a knack for manipulating people.
More than Mind Control: His unique skill 'Tempter' is basically this.
My Species Doth Protest Too Much: Other demons not of his line and even his fellow Primordials find him weird for not being just a Social Darwinist and obsessed with becoming ever stronger through battle and experience. Diablo for his part seems to just enjoy making them confused by his bizarre life choices.
No-Nonsense Nemesis: On the rare occasion someone genuinely makes him angry, any semblence of restraint and mercy go out the window and into a bottomless pit. The moment he attacked the three Luminaries he confronted, he consined them to oblivion without a second thought.
Noble Demon:
- While he utterly loves fighting and beating people up, whether into unconsiousness or death not really mattering to him, along with taking the souls of both dealmakers and his enemies, he's a generally decent guy who, even before being summoned by Rimuru, had plenty of standards. He only took the souls of people who genuinely were fully willing to die to have him accept a job, he always completed his deals to the letter and spirit of the word, even if the soul payment was lacking, viewing the souls of his targets as evening things out, and he was willing to give people that accidentally summon him out of desperation a simple agreement to keep his presence secret while letting them keep their souls so long as the deal was upheld.
- It's later revealed that being a Noble Demon is actually an inherent aspect of his very soul, as the very few demons that align with his "black" color (he just isn't very interested in creating tons of demon descendants like other Primordials) also possess very noble qualities, such as Beretta holding genuine loyalty to Ramiris not out of strength, since his true summoner Rimuru is stronger, but out of close companionship with her. Guy is able to realize Diablo has thrown his lot in with Rimuru simply from noticing this second-handed through Beretta long before the two Primordials ever meet each other again face-to-face.
No-Sell: He has [Pain Nullification], [Physical Attack Nullification], and [Abnormal Condition Nullification], which gives him Feel No Pain, makes physical attacks unable to hurt him (even a knife right through his heart), and immunity to status effects.
Not So Stoic: The normally composed and suave Black Progenitor is left in shock and disbelief after properly introducing himself to Rimuru only to be asked confusedly who exactly he is. It gets to the point it looks like he's about to cry when Rimuru cheerfully tells him he's free to go if he wants and he quickly reaffirms he wants to serve him.
Offhand Backhand: During his “fight” with Razen (really just Diablo playing around before taking the guy in), Diablo casually redirects Razen’s Nuclear Cannon spell up into the air…where it promptly vaporizes Pirone, one of Clayman’s Five Fingers and his primary spy. While Clayman believes this was merely a coincidence, as Pirone was concealed at the time, the narrative indicates that Diablo was actually aiming for the spy deliberately.
The One Guy: While gender doesn't really matter for demonic spirits who normally have no sex at all, out of the four Primordials under Rimuru he's the only one that identifies as male, whereas the other three possess the appearances and personas of women.
O.O.C. Is Serious Business: He is normally all smiles, even when facing an enemy. When he stops smiling and looks genuinely pissed, something is either going to die, or wish they were going to die. This has only even happend once so far in the novel, and the perpetrators (Three of the Seven Luminaries) were quite literally removed from the world entirely. It also happened in the spin-of Trinity of Tempest, where the leader of the slave trade in Blumund that was undermining Rimuru's goals in unifying humanity and monsters, Cockel, met an army of angry demons with Diablo promising that he would not die and be put to good use. The context of which was pretty clear.
Overnight Conquest: Not quite, but Diablo pretty much undermined Falmuth in record time, and even hints that this is nothing new to him.
Diablo: Taking over a country is trivial.
Overzealous Underling: Played with. Diablo is aware that Rimuru is a person who longs for peace and looks down on excessive actions, so Diablo restrains himself from attempting to just murder everything that's a potential threat (after asking for permission, of course) and follows his orders to the letter. However, he tends to assume Rimuru is thinking much farther forward into the future than he really is, so he's not afraid to take steps that would benefit Rimuru long-term in the process. This culminates when Diablo successfully convinces Guy Crimson that Rimuru is in fact The Chessmaster who is poised to take peaceful control of the entirety of the Western nations through economical and military might, which he technically is but that wasn't exactly the main goal. The light novel narration even notes that if Rimuru were present, he would be shouting at Diablo to shut up. This prompts Guy to make a personal visit to Tempest.
Pragmatic Villainy: While he is a Noble Demon, a big part of why he restrains himself even when particularly annoyed or enraged is because he knows that both his actions reflect on Rimuru's reputation due to his known allegiance throughout the kingdoms, and because he's very aware Rimuru's Nice Guy attitude leaves him looking down on...excessive actions and the last thing Diablo wants is for Rimuru to go Disappointed in You on him. Of course, when Rimuru does give him full reign to cut loose, he shows off exactly why he's still a demon.
Pretty Boy: Upon manifesting, he assumes the form of a beautiful, androgynous man.
Red Baron: The Black Progenitor. Later on he also becomes the Magic Lord.
The Rival:
- To Shion, who he competes with for the position of Rimuru's number-one aide.
- In ancient times, he was the rival of Rouge/Guy Crimson before the latter's ascension to Demon Lord, with the two of them having fought each other over who should be the ruler of demonkind. It cooled off after Diablo walked away from constantly trying to gain strength.
Scissors Cuts Rock: When Razen summons a Superior Spirit of Earth to fight him, Diablo admits that relying on the Tactical Rock–Paper–Scissors between demons, spirits, and angels is a smart concept...and then proceeds to one-shot the spirit, plainly stating one so young with so little experience has no chance against him.
Sharp-Dressed Man: His original attire has him dressed closer to higher nobility, while his attire after being named is heavy on the Battle Butler end of the trope. Either way, real threads like that would break most bank accounts.
Slasher Smile: If you see this on his face, don't bother running, You Are Already Dead.
- When summoned by one of the members of Silver Knights to take revenge on the archdemon that mortally-wounded her and killed her partner, he sports a bloodthirsty grin while saying he'll reap her enemies to make up the rest of what he's owed. This ended up being the Demon Orthos, the king, the chancellor, most of the knights, and every other demon and conspirator in the nation.
- After revealing to Rimuru the Seven Luminaries crime and receiving the order to "rub 'em out" his smile could only be described as horrifying. Most of his face consealed in shadow, revealing a beautiful silouette, and the most cordial smile one could manage. Given the context of what just happened, Rimuru (quite intentionally) signed the Luminaries death warrents.
Underestimating Badassery: He tends to be on the receiving end of this especially by those versed in demons, as they tend to assume he's "just" a Greater Demon at worst (due to him intentionally limiting his power) named Archdemon of a few centuries or even a millenia at best, not a Demon Peer and Primordial on the same age level of Guy Crimson. It's only the point he starts casually referring to his fellow Primordials by their colors like they're buddies (something unthinkable among demons if they aren't of comparable standing) that people realize what he really is and start shitting their pants.
Weak, but Skilled: Usually he is Strong and Skilled, but compared to his old rival Guy Crimson he is this. Guy kept gaining strength after Diablo lost interest in their rivalry, but Diablo's whimsical and eccentric nature (which his entire liniage gets) allowed him to learn things that should have been impossible for demons, such as holy magic.
Winged Humanoid: He can form bat wings out of his back.
Wolverine Claws: He can turn his hands into extendable claws.
You Do Not Want To Know: Touka tells the trio from "Trinity of Temptest" not to ask what Diablo did to Cockel, and considering how the last pannel with him went, it is sound advice.
Touka: Better not ask. You'll be happier that way.

Testarossa

Primordial Blanc / Killer Lord

Voiced by: Yumi Uchiyama (Japanese), Stephanie Young (English)^{Foreign VAs}

https://static.tvtropes.org/pmwiki/pub/images/coleus_episode_3___testarossa.png

An ancient and powerful Archdemon known as the White Progenitor whose presence was most often felt on the eastern half of the main continent in the lands ruled by the Eastern Empire. Intrigued by Diablo's praise of Rimuru, Blanc traveled to Tempest and ultimately agreed to serve the slime. Named Testarossa, she evolves into a Demon Peer and takes the role of ambassador and military adjutant to the Council of the West, serving as the voice of Tempest's interests to the human nations along with commanding the alliance armies that fall under Tempest's purview as head of continental defense.

Ambadassador: Rimuru appoints her as his ambassador to the Council of the West along with being the military adjutant. She's an ancient demon that can singlehandedly wipe out a country on her lonesome, and even discounting that she has the shrewd political acumen necessary to work against scheming senators.
Beware the Nice Ones: She's described as "cruel and kind in equal measure", and she can switch between the two on the fly.
Bullet Catch: Catches a sniper shot aimed for the back of her head without looking. For reference, the shot was moving at three times the speed of sound over a distance of about 15 feet, and her back was to the shooter.
Deal with the Devil: The "Lake Shore Dyed Scarlet Incident" was the end result one of these. The nation of Silberia was always under threat of complete subjugation by the Eastern Empire, so they made an ancient pact with her: in exchange for her promise to protect the nation until her eventual incarnation, a member of their line would become her ideal vessel. What finally pushed the king to act on that pact was when a corrupt noble attempted to take his daughter, Princess Blanche Nam Ul Silberia, as his concubine and was willing to use military force to get his way. Blanc took the body of the princess as payment and manifested into the world before doing battle with the Imperial Guard who obviously didn't want a second Guy Crimson. However, Blanc had grown to care for Blanche in their time together, and ultimately chose to leave her body and not consume her soul before burying her body unblemished.
The Dreaded: Even Diablo is wary of her, admitting that he would like to avoid a fight with her if at all possible, as well as mocking Rain during their fight that Testarossa would be a far more dangerous foe. Misery admits she'd rather not fight her unless she had to and preferable under conditions favorable to herself. The Eastern Empire in particularly is frightened of her, as her near incarnation caused the infamous "Lake Shore Dyed Scarlet Incident".
Early-Bird Cameo: Following in Ultima's footsteps, she makes a surprise cameo in the third episode of the Visions of Coleus OVA before her debut in the main anime, though unlike Ultima-as-Violet's prominent role as a Greater-Scope Villain, Testarossa-as-White only gets a small scene of her as a teaser.
Genius Bruiser: As one of the most powerful demons in the world the "Bruiser" part is self-evident. The "Genius" comes with how she's a social expert and had completely memorized all of Tempest's currently-under-construction laws and constitution while helpfully pointing out places that could be altered and corrected, which is how she got the ambassador job in the first place.
Hidden Heart of Gold: Despite the fact that Blanche willingly gave her body to Blanc earlier then their deal promised due to undergoing a Despair Event Horizon, Blanc didn't want to take it as she grew to care for Blanche as a friend and was saddened by her death.
Lady of War: She holds herself with a level of elegance and grace in her words and deeds, and she's a warrior fully capable of tearing someone apart with her bare hands.
Mark of the Supernatural: Not her, but rather the royal family of Silberia that made a Deal with the Devil with her. Their similar white hair and red eyes to her denoted their pact and the fact that they were over generations breeding the ideal host for her.
Ms. Fanservice: It is often commented and shown she has the most "mature" body of the three female Primordials and always carries herself with an air of sophsication that attracts others.
Mystical White Hair: Her white hair is often brought up as one of the features that enhances her striking beauty, and it denotes her otherworldly nature as one of the Primordial Demons.
Neck Snap: This is the fate she inflicts on one of the Eastern Empire's Imperial Guard that fought her during the "Lake Shore Dyed Scarlet Incident" when they meet again during the war with the Empire. Considering what she does next to the rest of the army, he got off pretty easily.
One-Hit Kill: Her abilities particularly specialize in "instant-death" techniques. Only those with sufficient spiritual strength can avoid being one-shotted by her, as her attacks will not only gruesomely mutate and kill the body but also extinguish a victim's soul.
One-Man Army: Her One-Hit Kill abilities allow her to instantly wipe out hundreds of thousands of foes at once.
Only Friend: She and Blanche were this to each other, as Blanche willingly offered her body in exchange for Blanc being her friend, while Blanc grew to care for Blanche during their time together and got revenge on those who wrong her after she assumed control of Blanche's body.
Red Eyes, Take Warning: Her striking red eyes are commented on often, and she is a dangerous demon. Those eyes also overlap with Magical Eye, as they allow her and those she offered her blessing to "see through anything".
Rivers of Blood: The "Lake Shore Dyed Scarlet Incident" got its name for this very reason once Blanc actually starting fighting the Imperial Army. Nearly ten thousand people died from her rampage, but to her it was just a "meal", and one she was rudely interrupted from enjoying in full at that.

Ultima

Primordial Violet / Pain Lord

Voiced by: Miyu Tomita (Japanese), Cristina Valenzuela (English)^{Foreign VAs}

https://static.tvtropes.org/pmwiki/pub/images/ultima_anime.png

An ancient and powerful Archdemon known as the Purple Progenitor whose presence was most often felt on the western half of the continent, watched over in inactivity by the True Demon Lord Luminous Valentine and Empress Elumeshia Elure Sarion. Intrigued by Diablo's praise of Rimuru, Violet traveled to Tempest and ultimately agreed to serve the slime. Named Ultima, she evolves into a Demon Peer and takes the role of Chief Prosectutor, leading Tempest's police force and public investigation agency.

Animorphism: She took the form of a cat when she joined up with Foss and her friends during "Trinity of Tempest".
Cats Are Magic: She's a millenia old demon and sometimes transforms into a cat for disguise.
Dark Is Not Evil: Less so than Diablo, but she's the Primordial with one of the darkest colors and while has the appropriate sadism you'd expect of a demon, she is capable of being kind, and she's a professional about her job to the point she goes out her way to ensure any arrests carried out are done according to procedure and with no corruption.
Deliberately Cute Child: Ultima isn't afraid of acting the part of a child, as it tends to make people underestimate her and she does enjoy at times being doted on.
The Dreaded: Less so than Blanc or Jaune since she made far fewer open moves of hostility, but Violet's presence in the western half of the continent made her a constantly watched figure by Luminous and Elumeshia in the event she went on a rampage.
Early-Bird Cameo: She makes her animated debut with a surprise appearance in the Big Damn Movie That Time I Got Reincarnated as a Slime the Movie: Scarlet Bonds before her appearance in the main anime as the Greater-Scope Villain, and indeed before her two rival Primordials. She then ups herself by appearing in the Visions of Coleus short story and the corresponding OVA. Even before that, she appeared in the spin-off manga "Trinity of Tempest" as a Stealth Mentor to the titular trinity.
Even Evil Has Standards: In the movie, her deal with the first queen of Raja was as much an attempt to eventually get herself a vessel as it was a game to test the resolve of Raja's royal bloodline in sacrificing themselves for the sake of their people. As such, she is not at all pleased to learn that Lacua effectively stacked the game in order to curry favour with her, and is quick to cut ties with him for ruining her entertainment and "cheating" on her behalf. While she was willing to watch generations of queens suffer for the sake of her own amusement, she wanted them to play the game willingly, and ultimately resurrects Towa and voids their contract as compensation.
Face of an Angel, Mind of a Demon: Her preferred appearance is an adorable young teen, to the point even Rimuru admitted on their first meeting he couldn't believe she was a demon, let alone an Archdemon. Even discount of being a literal demon, she's quite cruel and sadistic.
Fair-Play Villain: She likes to give the people she makes deals with a chance to get out of it; in Scarlet Bonds she actually lets the Queen of Raja go free from the contract because she feels that her minion manipulating the situation cheapened it for her.
Fate Worse than Death: The Primordial most likely to inflict this on her enemies. The others will usually settle for just putting the fear of all that's unholy into their victims before offing them, but Ultima prefers taking their souls captive and self-aware when she's done just so she can inflict more punishment on their helpless state for as long as she likes. Luckily, she only saves this particular fate for the ones who really draw her ire.
God Guise: In the movie, she tricked Queen Towa's first ancestor by letting her think she was a goddess so she could manipulate her into making a deal with her, which became the origin of the royal family's cursed tiara.
Greater-Scope Villain:
- In Scarlet Bonds, she was the one who gave the cursed tiara to Queen Towa's first ancestor, intending to use it as part of her Long Game to obtain a perfect incarnated vessel by slowly acclimating generations of the queens to the cursed poison within the tiara and thus her own power. She also subtly influenced the hardships of the nation of Raja, both external and internal, in order to provoke the queens into being willing to use the tiara's powers despite its risks. However, she also admits it was just as much a genuine test of the descendants' noble spirits that motivated her "game", all of whom impressed her. She also invented the prototype cursed poison magic circle that the film's antagonist would use to inflict the film's main disaster on Raja, though she notes that was never meant to be used on the human nation but instead as a "prank" on Luminous, while her subordinate went on his own initiative.
- In Visions of Coleus, her desire for a vessel to incarnate into is the crux behind the two Archdemons, Karl and Gustav, answering the summoning of Tedron Coleus, as they intended to turn his daughter Zenobia into her vessel while fulfilling the old king's own desire to steal the body of one of his sons, all to earn her favor. In this case, Gustav despite killing Karl for a power-up and Rimuru's interference actually succeeds in creating an incomplete vessel for Violet and lives to see it happen, but Violet is displeased both at the quality of Zenobia as a vessel and the fact Luminous Valentine, who in her current incarnation she cannot defeat, was witness to the whole thing, causing her to kill Gustav and leave Zenobia's body without harming it.
"Instant Death" Radius: She has access to a special ability, courtesy of her Ultimate Skill's sub-skill [World of Annihilation], a super-enhanced version of Rimuru's [Merciless], which allows her to kill anything and everything she uses it on that doesn't at least possess an Ultimate Skill. Rimuru outright forbids her from using it due to just how dangerous it is.
Irony: There is a level of irony in putting a demon in charge of law enforcement.
Kill It with Fire: Destroys the remainder of 100 Eastern Empire airships meant to attack Dwargon all at once with a single black Nuclear Flame spell. Major General Farraga in his final moments notes that what she casted was a spell beyond even a wizard like Gadra could make alone and a level higher than even the Seven Luminaries could create working together, and she still muses that she held it back if only to avoid catching Team Hiryu on the ground in the explosion.
Killer Rabbit: She's noted In-Universe to be adorable and initially unassuming, but she's fully willing and capable of killing and torturing people without batting an eye. Case in point, during the first proper engagement with the Eastern Empire, she boards an airship, pulls a Bullet Catch on the head officer emptying his pistol at her, kills their summoned Elemental they without much a struggle, and moves faster than they can see while decapitating people with her bare hands.
Kung-Fu Wizard: Like all Primordials she's a master of magic, but she's personally shown to also incredibly skilled in hand-to-hand combat. Most notably, she equaled Damrada of the Imperial Guard (No. 2 in the ranks at that) in hand-to-hand during the final battle of the war with the Empire, with her greater endurance giving her the edge.
Poisonous Person: One of her magic specialties is with poison. Her Ultimate Skill, [Poison King Samael], allows her to create any type of poison she desires and tailor it to her target's specific weaknesses, meaning nothing in existence is safe from her if she desires to.
Purple Is Powerful: She's the Monster Progenitor of the Violet-line of demons and the strongest of them all.
Reasonable Authority Figure:
- During the Scarlet Bond movie she willingly voids her contract with the queens of Raja once she learns that one of her subordinates interfered without her knowledge, and she brought Towa back to life after she sacrificed herself to save Hiiro, all when she could have taken Towa as her perfected vessel then and there.
- Once she joins Tempest, she is very adamant about enforcing a strict but fair system of law enforcement, with the very possibility of corruption in the ranks enraging her to the point she will deal with the corruption as swiftly and mercilessly as she can manage.
Sadist Teacher: She takes this role for Gabiru to toughen him up, which at least partially traumatizes him. And she actually likes Gabiru more than most.
Scissors Cuts Rock: One-ups Diablo's feat of destroying Razen's War Gnome by destroying an Ifrit summoned as a last-ditch effort by the Flying Combat Corps (summoned through the efforts of 50 magicians) by freezing it solid with a high-level magic spell and shattering it to pieces like she was just breathing, all while insulting the Ifrit as being far too weak against her.
Spanner in the Works: When the trio from "Trinity of Tempest" confront a slave trader in a Repulsive Ringmaster motif, the fool tries to summon a greater demon to kill them and run. Unfortunately, he attempts to call one of the Purple lineage, and the yet-to-be-named Ultima was acompanying them in cat form. The demon's response is succinct:
I refuse!
Teen Genius: From the perspective of those who don't know her true nature, she's viewed as this for being so young yet leading the investigation agency with such efficiency.

Carrera

Primordial Jaune / Menace Lord

Voiced by: Ikumi Hasegawa (Japanese), Emi Lo (English)^{Foreign VAs}

An ancient and powerful Archdemon known as the Yellow Progenitor whose presence was most often felt on the southern continent where she clashed almost daily with True Demon Lord Leon Cromwell. Intrigued by Diablo's praise of Rimuru, Jaune traveled to Tempest and ultimately agreed to serve the slime. Named Carrera, she evolves into a Demon Peer and takes the role of Chief Justice Officer of Tempest's Supreme Court, tasked with trying the criminals of the nation and handing out fair judgements of guilt and innocence.

All Crimes Are Equal: When she first got the job, she declared she would judge everyone equally under the sentence of death. Rimuru told her to please not do that and she agreed, dropping the angle.
Blood Knight: All the Primordials are guilty of this, but Carrera stands out. She considered firing Nuclear Magic daily at El Dorado a grand way to kill time, and was the one most eager to test Rimuru and see if he was as strong as Diablo claimed. In fact, the Yellow line of demons she's the progenitor of are considered the battle-junkies among demonkind to the point it's why they're generally considered "Unnegotiable" for summoners, as their love for battle and rampaging makes them too dangerous for most to handle.
Gravity Master: Her instant-kill magic usually manifests in creating singularities to wipe out all opposition. She wiped out most of the remainder of the Empire's Armored Corps, nearly 200,000 soldiers and advanced weaponry, with just one such spell.
Hanging Judge: Averted, as despite her very brief toe-dipping into All Crimes Are Equal, she and her subordinates are sworn to act within the law and not pervert it in such a way.
The Lad-ette: She's the most openly tomboyish and deliquent-like of the three female Primordials, wearing the least fancy clothing and having the most lax attitude of the bunch.
Person of Mass Destruction: Not only can she fire off Fantastic Nuke level spells and launch gravitational singularities capable of destroying cities and wiping out hundreds of thousands of enemies, but once she obtains her Ultimate Skill [Menace King Abbadon], her strongest attacks can consume the whole planet if she loses control of them.
Unskilled, but Strong: Compared to her fellow Tempest Primordials she's this. Carrera is noted to possess the largest supply of magicules of the four, and indeed, by the end of the Empire War she has more than Rimuru himself who is now an Ultimate Slime/True Dragon, albeit only if he's not relying on his spiritual links to Veldora and/or Velgrynd. She also has access and willingness to use the most obviously destructive spells of them all. As a consequence, however, her control, while still stellar by most standards, is noted to be the weakest of the Primordials because of her massive power and fiery nature and her go-to basic strategy is "Nuke 'em with extreme prejudice".
Worthy Opponent: She finds hers in Tatsuya Kondou of the Eastern Empire, unable to believe there existed a human capable of forcing her to fight with everything she has yet clearly relishing the opportunity to fight one such foe. She respects him so much that she heeds his Dying Request to kill Emperor Rudra and takes his golden God-class revolver as her own.

Black Numbers

Black Numbers in General

The Black Numbers is the name given to the demons under the command of Diablo, Testarossa, Ultima, and Carerra, consisting of the latter three's subordinate 200-strong individual armies and the 100 demons Diablo personally recruited. They are sub-commanded by the seven demon lieutenants directly under the Primordials: Venom, Moss, Cien, Veyron, Zonda, Agera, and Esprit.

Badass Army: While there may indeed be individuals in Tempest that are stronger, pound-for-pound the Black Numbers are the strongest fighting force in all of Tempest. This was in fact invoked by Diablo, who only accepted any demon that could impress him in combat and slaughtered the rest without remorse (slightly mitigated that demons have Resurrective Immortality, but that just gave him more reason to show no mercy).
Demonic Possession: All of them gained a physical body by possessing a specially-prepared Artificial Human body crafted by Rimuru, Ramiris, and some of the best scientific minds in Tempest.
The Legions of Hell: They are a total fighting force of 711 demons recruited from the underworld to serve Rimuru. Ironically, considering who Rimuru is they might very well be one of the most heroic depictions of this in fiction.
Super-Soldier: Here is a recipe for you: take a powerful demon hand-picked by one of the strongest Demons of Hell, give it a tailor-made Artificial Human body specifically made to serve as an ideal host, then give it a name from a True Demon Lord that causes it to drastically evolve. Rinse and repeat 710 more times. Needless to say, they are the best individual soldiers in the world.
Took a Level in Badass: Originally, the most numerous members of the Black Numbers were a number of stronger Lesser Demons that Diablo defeated and recruited in order to have them serve Rimuru. After giving them artificial bodies and naming them, they all evolve to the level of a Greater Demon.

Labyrinth

Lords of the Labyrinth

Labyrinth Bosses in General

The strongest monsters who reside within the giant Labyrinth created through the joint cooperation of Rimuru and Ramiris, which also serves various purposes as a training ground for both residents and adventurers, living quarters for certain monster races, research and development space, farming ground for certain magical plants, and in times of war even a safe haven for Tempest's and surrounding areas' citizens. The majority of them are those whose skills or appearances wouldn't be suited for the more public duties of managing Tempest's day-to-day operations or security.

Beef Gate: Their collective purpose is to act as this for the various floors.
Dark Is Not Evil: Each of the Labyrinth Lords are people with unsettling appearances, concerning personalities, and/or terrifying powersets, but all of them are actually quite nice and friendly, most notably the ones who joined Rimuru after getting beaten by him or his subordinates. That said, those freaky aspects are why they work in the Labyrinth in the first place, as they'd likely constantly terrify people if they were out and about, and said attributes also provide a good "dungeon boss" aesthetic when being Punch Clock Villains in the Labyrinth
Punch-Clock Villain: For a given value of "villain", but since they serve in times of peace as the bosses of the Labyrinth for adventurers to fight and earn the right to pass to the lower levels, they have to serve as obstacles and thus be aggressive. Some of them get much deeper into the role than others.
Undying Loyalty: All of them towards Rimuru, as per usual, though several of them also have this towards Ramiris.
Vitriolic Best Buds:
- While they get along with each other well, there is a element of competition in regards to their performances in the Labyrinth as they try to outdo each other to show off and gain Rimuru's favor.
- Apito and Kumara have a more intense varition of this.

Veldora Tempest

Storm Dragon

https://static.tvtropes.org/pmwiki/pub/images/veldora_human_anime.png

^{Click here to see his dragon form}

Voiced by: Tomoaki Maeno (Japanese), Chris Rager (English)^{Foreign VAs}

One of the Four True Dragons and the first intelligent being Rimuru meets after being reincarnated, he's the one who named him. He in turn received his last name from Rimuru. He had been sealed in a cave for three centuries when he met Rimuru, becoming his first friend.

Adaptational Early Appearance: In the manga and light novel, Rimuru gives him a body to inhabit after exchanging a few words to each other. In the anime, he gives him his body earlier after he awakens.
Awesome by Analysis: His Unique Skill [Investigator] allows him to consult a record of the world's event, which allows him to analyze things on a level that can match Great Sage's own appraisal abilities when he actually bothers to use it. It eventually evolves into the Ultimate Skill [Investigation King Faust] when Raphael practically bullies him into evolving a Skill to better help Rimuru that he bluffs he gained during Rimuru's Harvest Festival to save face, which boosts this ability with the addition of sub-skills "Probablity Estimation" and "Pursuit of Truth". These allow him to calculate the probablities of outcomes and boost the probablities in his favor to take precedence.
Awesome, but Impractical: Shockingly averted with the arts he got from Rimuru's manga. He was able to refine the techniques into reliable attacks with significant combat aplications. His version of the Hadouken has zero startup time and can be spammed, and his Kamehameha may have charge time, but it takes someone the likes of Milim to be able to nullify it, with the shockwave being able to knock a Demon Lord off their feet even if it only went off near them.
Awesome McCoolname: His reaction to Rimuru giving him the name "Tempest" is to loudly proclaim that it is a fantastic name.
Baritone of Strength: In the dub, he has a deep voice — underscoring that he's a powerful dragon-god.
The Big Guy: For all of the nation of Tempest. He is the most powerful member of the nation and has the most experience in destruction, but not the most common sense. He is smart enough not to be The Brute, but not too bright when it comes to keeping his foot out of his mouth.
Bishōnen Line: Played with. His human form is actually physically weaker than his dragon one especially in the strength and durability department, but this is the form that lets him use the techniques he learned from his manga and training to their full potential.
Blood Knight: While not malicious, he needs to cut loose every once in a while. This is one of the reasons for his sealing.
Brains and Brawn: He is the Brawn to Rimuru's Brains, as while Veldora is (or rather was initially until Rimuru's evolution into the Ultimate Slime) far stronger then Rimuru, he was shown to not consider the long-term consequences of his actions, unlike Rimuru who plans in advance.
Calling Your Attacks: Thanks to all of his "training" both inside Rimuru's mind and from reading numerous manga, he's developed the habit of spouting attack names to create specific focused attacks. Of course, due to said "training", every single one of his called attacks is directly based on and named for a pre-existing fictional one, such as Hadouken, Shoryuken, Tatsumaki Senpukyaku, and Kamehameha.
Cool Uncle: Milim certianly thinks so. The two of them have matching personalities and get along without any issue.
Destructive Savior: Near the end of the story he tries to make an apology of sorts to Ruminas for blowing up her kingdom that one time only to destroy it again first through collateral damage and then accidentally turning the entire place into a forest.
Dramatically Missing the Point: His perspective is given focus at the ends of volumes and, while he learns compassion and patience from Rimuru's memories, he still appreciates his actions from the perspective of an immortal unassailable dragon and not a humble mortal not fully aware or invested in their own power. In this way, he rationalizes Rimura's actions and luck as shrewd prudence and not the serendipity it is.
The Dreaded: Very much so. He was indirectly responsible for the peace within Jura Forest due to his sheer presence alone. However, his disappearance sparks a war for territorial control between the monster races, at least until Rimuru arrives.
Final Boss: He serves as this for the Labyrinth, being the final opponent on Floor 100.
Heel Realization: His time within Rimuru's Stomach watching the slime and his interactions allowed him time to properly reflect that the old him that rampaged without care was kind of an asshole. He admits when before he didn't really care about his random destruction, such as blowing up Luminous' old kingdom, he now has the presence of mind to feel bad.
Hidden Depths: His POV sidestory reveals he's picked up Shogi and gives Ifrit a handicap. He also takes to reading manga and quoting lines that he likes.
Humanity Ensues: After figuring out how to disable Unlimited Imprisonment, Rimuru discovered that Veldora got rid of his physical body — not needing it while inside Rimuru — and creates a duplicate body and sticks Veldora's soul inside of it. Veldora makes a few modifications — turning the hair blond and making it taller and more muscular — and then lets out an evil laugh while declaring his triumphant return and intent to annihilate any who oppose him. However, he spends most of his time lazing around reading manga.
I Hate Past Me: He considers himself in the past an idiot who couldn't appreciate anything but power.
I Know Mortal Kombat:
- He picked up actual combat strategy and techniques mainly from reading Rimuru's supply of manga, or as he calls them the "sacred texts". This includes emulating iconic attacks from various fighting games and shōnen manga.
- He later develops his own signature fighting style, which he named the "Veldora Killing Arts", which incorporate elements from manga fighting styles and new ways to use his powers rather then his previous brute force approach.
Immortal Immaturity: Despite being one of the most ancient and powerful beings in the world, mentally Veldora is basically a somewhat bratty, self-centered teenager, full of petty impulses and uncontrolled whims, with Rimuru actually being a more mature and responsible part of their friendship. This led to no end of annoyance from his older sisters, as they were basically stuck trying to raise him more responsibly.
Immortal Procreation Clause: He implies he can breed but doesn't bother because living forever means he doesn't need to leave descendants. He says most magic born creatures think like that. Milim is also a good example as to why it would be a bad idea: When dragons reproduce, their power is almost entirely absorbed by their offspring. And assuming Rimuru is Veldanava, it took one hell of a long time to reincarnate compared to normal, if he did at all.
Implausible Deniability: He mentions that he destroyed a vampires' city out of pettiness, and then pretended he had nothing to do with it. Understandably, no one believed him.
I Need to Go Iron My Dog: When Rimuru learns that Veldora interrupted Diablo in the middle of his Falmuth-domination mission, and thus potentially making Diablo mess up, Rimuru gets so angry that Veldora tries to excuse himself by claiming he needs to use the bathroom. Unfortunately for him, being a spiritual lifeform that converts all food directly into energy means he never needs to use the bathroom, something Rimuru knows, so despite his best effort he can't avoid being scolded, having his special pudding confiscated, and getting his snack privileges revoked for a while.
Intergenerational Friendship: When they first met, Veldora was thousands, if not tens of thousands years old, and Rimuru was just 37 (or about 1 week as a slime). Ironically, he turned out much more mature than Veldora.
Kamehame Hadoken: By reading the "sacred texts", Veldora learns how to do the Kamehameha and Hadoken, and in the anime uses them in his short fight against Milim.
Ki Manipulation: One of the most important "lessons" Veldora learned from his "sacred texts" is the manipulation of life energy to concentrate it into skillful attacks, and applying that to the immense amount of magic constantly generated and emanating from his body, instead of just thoughtlessly throwing his magical weight around. It allows him to not only suppress his aura to obscure his identity or make mana-sensing characters think he weakened, but also apply genuine skill to combat that gets rid of his original skill-less predictability that got his ass handed to him frequently by his older sisters.
Large Ham: As expected from a dragon, he's bombastic and loud whenever he's excited.
Meaningful Name: Not his original name, but the surname that Rimuru gave him. Tempest fits him for all the same reasons that it fits Rimuru, his very presence causing every monster in the forest to play nice, his disappearance creating a massive turf war, and his re-emergence putting the whole world on edge.
Morton's Fork: His incredible magicule generation unfortunately led him to this scenario. Either he rampages to deplete them, destroying the countryside and garnering peoples hate, or he lets them erupt naturally, creating overpowered monsters like Charybdis, which destroy the countryside and garner even more hate for Veldora. Rimuru creating the Labyrinth was a blessing for him, since he could release his magicules in the depths, so monsters in the labyrinth could be culled by adventurers and the dungeon bosses, and the countryside and populace would eventually stop hating him.
Mundane Utility: Not quite as mundane as most examples, but the constant release of magicules from him in his chamber at the bottom of the labyrinth contaminates ores and plants to make the Magic Ore and Hipokute Herbs used for various products that Tempest produces that are almost exclusive to them, being mass-produced Magisteel and Full-Potions.
Otaku: He loves reading manga, which he refers to as "sacred texts".
Pent-Up Power Peril: If he holds in his power for too long without releasing it, it will eventually all come out in a massive eruption, sufficient to level all of Tempest and kill just about everyone inside, not to mention the massive storm of magicules from the release and all the deaths happening at once could result in the birth of a creature on par with or even stronger than Charbydis. That's the reason why Rimuru and Ramiris eventually build the Tempest Labyrinth, so he can have a place to safely let off his excess power without threatening anyone or spawning dangerous monster hordes. The first time he released his magicules in the labyrinth, they came out with the force of a bomb going off, the shockwave alone being capable of killing a regular human.
Person of Mass Destruction: His rampages were so destructive and common before he was sealed that he was treated less like a living creature and more like the incarnation of a natural disaster; with very few exceptions (hello, Luminous), the general populace treated any death and destruction he caused as no more worth getting worked up over and swearing revenge on than doing so against a hurricane or earthquake.
Really 700 Years Old: He's practically ageless and has lived for millennia already. The three hundred years he's spent sealed up has him more worried that it'll kill him through the draining of his magic power than actually through old age.
Red Baron: Everybody in the world took up calling him the "Evil Dragon" because, unlike his eldest brother and older sisters, he was such a Blood Knight that rampages, destruction, and fighting were pretty much his reason for living. Following his bonding with Rimuru and eventual release from his seal, which he complimented by acting Willfully Weak through suppressing his Battle Aura, everybody who has yet to meet him again following his release constantly expresses surprise that he's no longer living up to his nickname.
Resurrective Immortality: Like all true dragons Veldora can respawn after death, albeit without most of his previous incarnation's memories (though Rimuru's two years housing Veldora granted him a skill to back-up Veldora's memories, ending this limit provided Rimuru's still alive). This was something of a problem for his upbringing, as his oldest sister Velzard was so exasperated by his bratty attitude that she got into a habit of killing him and hoping maybe he'd learn something for his next reincarnation, but the memory loss always got in the way. Being completely drained by Unlimited Imprisonment would have killed him permanently, though.
Sealed Evil in a Can: He was sealed by the Hero for blowing too much stuff up, basically. He's not exactly malicious but he basically gets bored and goes on rampages every now and then. After being unsealed he contains himself by reading manga, griefing newbies inside the labyrinth and eating cake.
Ship Tease: He gets very familiar with Ifrit while they're both trapped within Rimuru. In the manga he thinks about giving them a woman's body with breasts to explore their appeal, and in the anime spends an awkward amount of time holding their hand because they're warm.
Signature Laugh: Veldora has signature laugh (Kha-ha-ha!) whenever he gets excited.
Smarter Than You Look: Even before he started maturing, his vocabulary was incredibly varied, using words like unctuous (excessively or ingratiatingly flattering) in the proper context.
Smug Super: He is an immortal among the four strongest beings on the planet and is exactly as arrogant as that would imply. He mostly grows out of it.
Sore Loser: He keeps trying to find a way out of his loss to Ifrit in shogi before finally just awkwardly laughing to cover up his disappointment. Granted, he does take it better than one might expect. It is averted with those who beat him in combat (few as they are) and his loss to a human gave him a fair deal of respect for the race.
Strong and Skilled: His time inside Rimuru's stomach, observing the world through his eyes, allowed him to learn the importance of tactics and concentrated strikes. His study of the "Sacred Texts" granted him access to many useful techniques and he has learned to contain his power and use it efficiently. He had already learned to stop underestimating opponents and respect others who can challenge him, due to the hero that defeated him 300 years prior.
Supreme Chef: The last thing anyone expected him to be was this. He first revealed it when he taught the Crusaders how to cook sukiyaki to the level of a master, and then ran a takoyaki stand to roaring success.
Sweet Tooth: While he enjoys various foods made in Tempest, he especially loves sweets, just like his niece Milim. Also like her, he can be coerced into doing things through Food as Bribe if it involves sweets, and when Rimuru wants to punish him for acting out of line, he'll ban the dragon from being served any for a few days.
Taking the Heat: He happily took the blame for Rimuru massacring 20,000 Falmuth soldiers to preserve Rimuru's peaceful reputation in politics. Seeing as how Veldora is already seen as a dreaded Blood Knight, it's not like taking the blame really affects him.
Took a Level in Badass: He was already a badass before the series started, but was overshadowed by his sisters thanks to their better control over their skills, in addition to having Ultimate Skills that rendered [Investigator] useless. After learning to use actual technique and skill and gaining [Investigation King Faust], he's able to turn the tables on his sister Velgrynd, due to having double her magicule capacity (although technically she wasn't at full strength due to splitting part of her power off into several Parallel Existences) and no longer being a simple brute, as well as having an Ultimate Skill of his own, rendering the sister's unfair advantage null and void even if it still doesn't save him from becoming Brainwashed and Crazy. On the other hand, this improvement isn't enough to defeat Velzard in their practice battle, who still kicked his ass, but she compliments him on how she actually has to try now rather than just handing him a Curb-Stomp Battle.
Tsundere: He acts tough and aggressive, but can get flustered — even called one by Rimuru when he denies something.
Unskilled, but Strong: Before his imprisonment, he just tended to throw his power around carelessly. His two elder sisters are actually weaker, but Velzard and Velgrynd would always kick his ass because they had much better control of their abilities. In fact, when Velgrynd fights Veldora during the war with the Empire, she only has about half as his magicule capacity, but Veldora was still worried about his chances of winning. Thanks to the influence of Rimuru's manga and the wisdom of the people around him, however, he starts seeing the value of concentrated strikes, holding back his immense power and using actual techniques. By the end of the web novel, while Velzard is still generally considered to be the strongest dragon, he's improved at least enough to completely hand Velgrynd and titan Dagruel their asses, indicating that if he keeps it up he'll probably surpass Velzard as well.
Walking Shirtless Scene: His human form doesn't wear a shirt.
Weather Manipulation: As his dragon type might suggest, the majority of his special offensive techniques are storm-based, specifically in some combination of wind and lightning.
Willfully Weak: Following the release of his seal, and on the request of Rimuru, Veldora utilizes the aura-control techniques he learned by reading Rimuru's mental collection of manga to suppress his Battle Aura to a fraction of what it truly is, along with using his friendship with Rimuru to tame his Blood Knight impulses. This constantly bewilders everybody outside Tempest who know through rumors he revived but don't know the true reason why, as the fact his aura is so weak and he's stopped rampaging constantly is so unlike the Veldora they knew, with his sisters being particularly bewildered since in all the eons they've known him, "restraint" and "respect" were basically foreign concepts for the guy.
Worthy Opponent: The Hero who sealed him away became one to him, to the point where he laments that he would likely never see his opponent again due to her being of human birth. His defeat at her hands gave him an interest in humans as a whole. Of course, that Hero is in fact Chloe, and he does indeed get his rematch...kinda. If you want to get technical, it was Hinata who took the lead for defeating Veldora in the past as revenge for their own fight in the Labyrinth, and in the rematch it was Chronoa who fought him.

Zegion

Mist Lord

https://static.tvtropes.org/pmwiki/pub/images/ln_13_09.png

Voiced by: Yuichiro Umehara (Japanese), Greg Ayres (English)

An insect monster who Rimuru originally encountered as an injured large rhinoceros/stag beetle-like creature protecting Apito. On a whim of kindness Rimuru healed him and brought him to one of the deepest floors of the Labyrinth believing he would be safe there from threats. What Rimuru didn't realize at the time was that Zegion is an Insectar, a dimensional-traveling insect race that made war with the angels and is considered a natural enemy of demons. Touched by Rimuru's kindness, Zegion sought to repay his perceived debt and eventually evolved and grew in power to become one of his strongest subordinates alongside Diablo and Benimaru.

The Apprentice: He is one to Veldora, as the latter becomes his sparring partner and even teaches him his signature "Veldora Killing Arts".
Beyond the Impossible: He manhandled the elites of the Eastern Empire, one of which had a Psudo-Ultimate Skill, while Zegion at most had Extra-Skills. Considering that lesser skill users should not be able to affect Ultimate skill users, this feat proved Zegion to be one of the most dangerous entities in the world.
Big Creepy-Crawlies: Even in his original form he was an unusually-large rhinoceros/stag beetle (he had both a rhinoceros beetle's singular horn out the face but also stag-beetle like horns out the sides of his head) nearly as big as a child. After his evolutions he turned into a giant muscled bug man who towers over most people.
Black Knight: Upon his evolutions into a humanoid form he kept his black carparace, which makes him appear as a giant clad in black armor who is also an incredibly powerful and quiet warrior.
Casting Gag: He's a creature of few words who is extremely diligent about his work. Fittingly enough, his Japanese VA chosen for the anime has voiced at least two other characters who match the same description.
Curb-Stomp Battle: Almost every single fight he gets into turns into one of these. In his proper debut fight, he defeats four of the strongest fighters of the Empire's Armored Division completely and utterly with no injury to himself within minutes. For reference, three of the four were undercover Royal Guards that had managed to defeat Adalman, Albert, and their Death Dragon while being the Sole Survivors of the 100 that fought them and Adalman's undead legion, while the fourth and strongest, Sir Minute, had defeated Apito on his own. And he allowed them several hours to recuperate themselves from their injuries before letting them challenge him. Later on, he fights Carrion after the latter ascends to True Demon Lord status and also one-shots him after Carrion proved his newfound strength by defeating fellow Labyrinth Lords Adalman, Albert, Wenti (the newly-named Death Dragon), and Kumara. Sure, Zegion had also undergone his True Demon Lord evolution, but so had Adalman and Kumara with Albert and Wenti receiving power boosts from the former's awakening. He's even able to defeat Dino without too much difficulty, though the point is made that Dino didn't go all out even then out of half-heartedness.
Early-Bird Cameo: Alongside Apito, he makes his first animated appearance in The Slime Diaries Episode 9 before his proper debut in the main anime.
From Nobody to Nightmare: One of the notable in the series to rival Rimuru himself. He went from his introduction as a heavily injured beetle monster to acknowledged as one of the strongest, if not a heavy contender for the strongest, of Rimuru's warriors. Even Diablo acknowledges his strength and admits he can't afford to give anything less than his best when they spar.
Heroic Self-Deprecation: No matter how strong he gets, he constantly feels like he still has room to improve in order to better acquit himself in Rimuru's eyes and so further immerses himself in training...despite the fact even Rimuru himself is wary of actually crossing blows with someone of Zegion's strength and skill.
The Leader: He is both the Overseer of the Labyrinth and the Captain of the other Labyrinth bosses, and only technically under Rimuru, Ramiris, and Veldora themselves in authority in that regard.
Like Brother and Sister: He and Apito view each other like family, to the point Zegion was gravely injured protecting her from other monsters before meeting Rimuru.
Making a Splash: The "Mist Lord" title isn't just being fancy or a reference to his Ultimate Skill, as Zegion also has a near-absolute manipulation and control of water. This includes the water vapor in the air or the water inside living bodies.
Master of All: After Zegion's True Demon Lord evolution and acquisition of his Ultimate Skill; Illusion King Mephisto, Ciel had observed that Zegion had become a strong all-rounded fighter, capable in terms of both his physical and mental abilities.
Master of Illusion: He gains this ability via the effect of his Ultimate Skill; Illusion King Mephisto. It is stated to be the strongest skill in terms of illusions as it allowed Zegion to withstand the effects of Dino's Slothful King Belphegor.
The Quiet One: Blood Knight tendencies aside, his usual attitude is of a calm person who doesn't talk too much.
Rank Up: He was formerly the Boss of the 80th Floor but eventually promoted to the Captain of the Labyrinth Lords and the Labyrinth Overseer.
Space Master: He can teleport himself and others freely, disort space to create absolute defenses against attacks, and sever/disconnect dimensions and space at will to tear anything of his choosing apart.
Super-Toughness: His defensive power is one of the greatest in Tempest because he assimilated Magisteel into his exoskeleton to turn it into Adamantine, which makes his shell harder than diamonds while also being fully flexible. Upon his evolution to Demon Lord he transformed his armor into "God Steel" through sheer willpower, meaning his toughness rivals if not surpasses the Infinity+1 Armor of the setting.
Superweapon Surprise: To the most unpleasant surprise of the Eastern Empire invaders and the angels. Zegion was kept secret intentionally by Raphael and Veldora until the Eastern Empire's elites engaged him, in which his incredible power and skill wiped them out in record time. Rimuru intentionally kept the secret for when the Angels tried their luck with a brainwased Dino, only for him to reveal Zegion with another one sided fight in the Insectar's favor.
Took a Level in Badass: One of the biggest examples in the series! He started as a beetle roughly the size of a small child, and eventually grew into one of the top contenders for 'Strongest in Tempest'. Starting when he got "Absolute Defense" from Raphael and then honing his training from Veldora, he became so strong that even Rimuru got scared. It got to the point where he is a worthy sparring partner for Veldora.
Tough Beetles: He's a beetle monster that's acknowledged hands down as one of the strongest beings in all of Tempest.
Undying Loyalty: There is none more loyal to Rimuru then Zegion, and the most anyone in Tempest can do is match his sheer resolve to serve his lord. The slightest insult to his lord will result in the offender reciving a beating that none shall soon forget, if they survive.

Apito

Insect Queen

Voiced by: Reina Ueda (Japanese), Karan Ashley (English)^{Foreign VAs}

An Army Bee monster Rimuru originally encountered on a stroll through the Great Jura Forest being protected from other monsters by an injured Zegion. After he rescued and healed them, the grateful Apito became the major maker of the honey Rimuru grew to love, and desired to grow stronger herself so that she could better serve him.

Big Creepy-Crawlies: Even as an Army Bee, she was large enough to be comparable in size to a child.
Bishōnen Line: Goes from a giant bee to a beautiful bee woman upon her evolution.
Early-Bird Cameo: Alongside Zegion, she makes her first animated appearance in The Slime Diaries Episode 9 before her proper debut in the main anime.
Fragile Speedster: She's incredibly fast, but her durability is on the low end for a monster of her level, and her attacks rely on being extremely fast and having various properties like poison rather than brute force. As such, she tends to struggle with foes as fast as herself or can restrict her speed.
Insect Queen: It's in her name. Specifically, she can create swarms of insects at her command, which serve her like a Flunky Boss.
Like Brother and Sister: Her relationship with Zegion. It's so close in fact when Zegion underwent the True Demon Lord ascension, she received a power boost from it due to how close they are.
Rank Up: She was originally the unofficial boss of the 79th Floor before Zegion, but after Zegion was promoted to Labyrinth Overseer she took his spot as the Boss of the 80th Floor.
Took a Level in Badass: She used to be a rather weak monster who Zegion always protected. One Bishōnen Line and training with Hinata later, and she's a Fragile Speedster able to fight evenly with Sir Minute, one of the higher-ranking members of the Eastern Empire's Armored Corps. Rimuru himself pegs her on a purely physical level without factoring in magic a match for Hinata.
Undying Loyalty: Like Zegion, she is almost fanatic in her loyalty.
Vocal Dissonance: Reina Ueda gives her a soothingly gentle, calm, and friendly yet moderately deep voice, which perfectly fits both her friendly personality and beautiful Bishōnen Line form, but clashes a bit with her original giant bee look.

Adalman

The Index Finger

Voiced by: Tomokazu Sugita (Japanese), J. Michael Tatum (English)^{Foreign VAs}

A Wight King that was once a faithful Sage of Luminism. Tricked by corrupt members of the Church into going to his death fighting a Zombie Dragon and its undead army, Adalman's spirit was polluted by the death magic and was resurrected as an undead himself alongside his allies and even enemies. Bound by a curse from Demon Lord Kazaream, Adalman served as Clayman's Index Finger until the war with Tempest when his curse was purified by Shuna, and astounded by her faith in Rimuru he decided to dedicate himself to his new "god" with much fevor.

Badass Preacher: In life he was a devoted follower of Luminism who became a Sage and would have become a Saint had it not been for the Uriah Gambit that claimed his life, and he spent his time wandering the lands slaying monsters with Holy Magic and spreading his faith. As a wight, he retains that faith now as a follower of his "god" Rimuru and is a Necromancer who commands legions of undead and powerful magic.
Came Back Wrong: He was resurrected by the Secret Art of Resurrection created by his friend Gadra, who suspected foul play about the Uriah Gambit and casted it without Adalman's knowledge. However, the miasma of the zombie army had already infected his soul, causing him to revive as a wight. Thankfully, his personality itself wasn't affected by the transformation, rather by the understandable belief his god had abandoned him in his time of need.
Dark Is Not Evil: He's a lich and necromancer who dresses in black and plays up the Evil Is Hammy angle in his role as a Labyrinth Lord, but he's a very personable fellow.
Defeat Means Friendship: Ironically, despite getting into a Mutual Kill with the zombie dragon that resulted in him becoming an undead in the first place, Adalman ended up befriending the creature in undeath.
Dem Bones: He lost all his flesh after he became a wight. Ironically, he could have regained it as Albert and Wenti did with their evolutions if he truly wanted to, but he grew to accept his new form.
Ghostly Glide: As shown in the anime following his defeat by Shuna, him being a living skeleton without any muscle for fine motor control means it's much more efficient for him to just limply float around using magic, combining this with Power Floats. His movement even comes with a stereotypical ghostly Scare Chord-like sound effect.
Glowing Eyelights of Undeath: As a signifier of his magical prowess, he's the only fully skeletal undead among his undead forces that has bright blue fiery lights glowing in his empty eyesockets. The light dims and brightens based on his emotions, making him quite expressive in spite of his skull-face, even going from extinguished to near-instantly burning big and bright when his faith is reignited.
Heel–Faith Turn: Ironically after having his Crisis of Faith over Luminism, his battle with Shuna allows him to come to terms with his feelings of betrayal and he regains his faith, instead becoming a follower of "Rimuruism" and a stauch ally.
Hoist by His Own Petard: Effectively inverted with Shuna's reversal of his Disintegration, which rather than obliterating him instead broke the curse that bound him and his undead followers to the land of Clayman and forced them to follow his will. With them no longer forced to serve Clayman but somehow still existing on the living plane, they took it as a sign for a greater purpose and swore servitude to Rimuru, gaining a much happier and more enjoyable un-life than they had before.
Holy Burns Evil: Undead are particularly vulnerable to Holy magic, which is somewhat awkward for a lich whose mightiest spells are Holy-based. As part of a long-overdue apology for what happened to him because of the Seven Luminaries, Luminous teaches him Holy-Demonic Reversal, which allows him to ignore his holy weakness to cast his miracles with impunity as well as dealing with one of his biggest weaknesses.
I Cannot Self-Terminate: Kazaream's curse prevents him from taking his own life, something he would have done long ago otherwise. Shuna helps him by turning his Disintegration into fuel for magic to free him and the other undead, who now have new purpose.
Our Liches Are Different: He's got the skeletal appearance and dead-raising/commanding powers down pat, but alongside how he never wanted to become a lich and primarily possesses holy magic, there's also the fact he doesn't have a Soul Jar, but rather that he is a soul jar, specifically for the souls of his undead army. Thus, the only way to permanently stop his infinitely regenerating undead is to defeat him.
Rank Up: He was initially placed as the Boss of the 60th Floor alongside Albert and the Death Dragon, but they improved enough that they were moved up to the 70th Floor.
True Companions: Albert, Wenti, Gadra, Adalman managed to acquire quite a few powerful and loyal friends.
Undead Barefooter: Being a living skeleton without skin, flesh, or even nerves to make contact with the ground uncomfortable, he doesn't bother including any form of footwear with his priest outfit. His status as a powerful lich who uses a Ghostly Glide for movement anyway also qualifies for Magical Barefooter.
Uriah Gambit: The victim of one by the Seven Luminaries of the Church, who feared his rising status as a Sage who might eventually become a Saint and thus threaten their "exclusive" rights as Ruminas' chosen. They sent him and his closest allies to subdue a massive Zombie Apocalypse fully expecting him to die in the process. Rimuru however suspects that for the Luminaries' leader Granbell Rosso, this was instead the final test of Adalman's worthiness to be a new True Hero of humanity and he actually would have preferred Adalman return alive and victorious.
Warrior Prince: He was the second prince of a small nation under the Holy Empire of Ruberios' banner, and since his older brother had already ascended to the throne and sired an heir to continue the line, Adalman instead threw himself into his studies and faith to become a templar knight of the Church.

Albert

Gehenna Paladin

Adalman's close friend in life, Albert was a paladin of the Western Saints Church renowned for his swordsmanship. He followed Adalman to his fateful battle with the Zombie Dragon and its undead army and perished from his wounds, but was revived with Adalman as a skeleton. Albert's loyalty to his friend has never wavered through life and undeath, serving as his sword and shield no matter where the wight goes.

Curb-Stomp Battle: He dealt this to the Empire Otherworlder trio of Shinji, Marc, and Zhen, defeating all of them with a single blow each as a show of what he could do now as a Death Paladin. Particularly impressive since up to this point, the trio had been steamrolling the Labyrinth on a scale unmatched by any other challengers, being the first party after Masayuki's own to clear the 50th Floor and even Rimuru thought they'd be able to take down Adalman and his guys without much trouble. Only Shinji managed to get out an attack on him at all with Holy Cannon, but Albert just No Selled it thanks to Adalman's Holy-Demonic Reversal before cutting him down.
Defeat Means Friendship: Much like Adalman, he ended up becoming close comrades with the Zombie Dragon that they got into a Mutual Kill with in life.
Master Swordsman: A veteran of countless battles and centuries of experience under his belt, he's one of the few swordsmen in the whole world capable of rivaling Hakurou in combat with nothing but pure skill.
Required Secondary Powers: His undeath is a boon for his sword, which consumes both the users lifeforce as well as the enemies. As an undead, he has no lifeforce to be consumed.
Undying Loyalty: His loyalty and friendship to Adalman is his defining trait. Be it traveling with him across the land slaying monsters and spreading the faith of Luminism, fighting a hopeless battle to the death against a miniature Zombie Apocalypse, spending centuries bound by a curse to a Demon Lord, Albert has followed Adalman through thick and thin for all time.
Warrior Undead: He was a major Master Swordsman in life, and even after dying and reviving as a walking corpse he still retained his talent with a blade, and in fact he continued refining his skills through centuries of undeath, to the point of being able to rival Hakurou in his prowess.
Wrecked Weapon: His Cursed Sword is shattered to pieces by Imperial Guardian Krishna during their battle in the Labyrinth, signaling the turning point of the fight where the surviving three Guardians finish off Albert, Adalman, and the death dragon, thus claiming the first of the few legtimitate Empire victories of that particular overall Curb-Stomp Battle.

Wenti

Death Dragon King

https://static.tvtropes.org/pmwiki/pub/images/venti_ln.png

A Zombie Dragon that gathered a large army of undead near the Great Jura Forest ages ago in the past, Adalman, Albert and several close fighters were tasked with stopping it from causing a widespread catastrophe. While ultimately everyone perished on that day, Adalman's resurrection as a Wight King revived them all and they found themselves strange bedfellows and even friends in the intervening centuries, with the undead beast evolving into a Death Dragon. Not technically a Labyrinth Lord like Adalman or Albert, but she's still listed here since she always fights alongside them.

Bishōnen Line: Goes from a towering rotting-looking Dracolich to a ghostly-looking Cute Monster Girl.
Cute Monster Girl: Once she evolves into a Dragon King after being named by Rimuru, she assumes the form of a beautiful (if still ghostly-looking) girl.
Dracolich: She's a 20 meter-long undead dragon that has a corrosive Breath Weapon, high strength and speed, and can regenerate from any injury as long as Adalman is alright. Shuna called her the pinnacle of undead.
Pulling Themselves Together: Back when she was a dracolich, unlike the skeletons and zombies that required Adalman to reconstitute their bodies with necromantic magic when slain, her undead power was so strong she could on her own rapidly pull her body back together after being sliced to chunks by Souei, and the fact Adalman acted as her Soul Jar meant soul-killing attacks wouldn't work on her directly.
Samus Is a Girl: Her gender was never once hinted at until she was named by Rimuru and became a Cute Monster Girl.
Sinister Scythe: Just to complete the creepy death vibes, she wields a large black scythe after becoming a Dragon King.

Gadra

Imperial Wizard

Formerly the Court Magician of the Eastern Empire, he is one of the few citizens who does not hold absolute loyalty to Rimuru, but rather to his best friend Adalman. His disgust and hatred of the Seven Luminaries is what drove him to serve the Empire in the first place, and when he learned that Tempest has slaughtered the Luminaries, he defected to them without a second thought. Currently resides as a hidden boss on Floor 60.

The Archmage: Remember Razen, considered by many to be the finest mage in the Western Nations and the pinnacle of what a human can achieve? Gadra was his teacher, and his knowledge and skill far surpass Razen's even after all these centuries.
Asskicking Leads to Leadership: He was the leader of the Empire's Magic Corps and their finest mage, capable of handing Saare and Grigori a Curb-Stomp Battle at the same time. This then became played with when the Magic Corps was disbanded and folded into the Armored Corps to better utilize Magitek and he lost his position, but he stills remains a high-ranking member of the Imperial Court whose word carries weight.
Best Friend: To Adalman, to the point where he did not want him to fall to the Uriah Gambit of the Seven Luminaries, and cast his secret skill ‘Reincarnation’ on him in case he was killed, not knowing his soul would be tainted by the miasma of the undead.
Born-Again Immortality: His Reincarnation magic works works very similarly to Ramiris' system of Resurrective Immortality, where whenever Gadra dies, he is reborn as an infant with all his memories and knowledge intact, and can thus continue to gain experience and hone his ability through the ages.
Cool Teacher: He acts as this for the Otherworlders in the Empire. Gadra teaches them about the world and how to use their abilities while they in turn tell him about their original worlds. He's heavily respected by them and he himself enjoys their company. He even personally vouched for several of them in order to prevent Rimuru from possibly killing them and letting them join Tempest.
Deal with the Devil: With Diablo being the devil in question. In exchange for mutual service to Rimuru Tempest (who helped his friend Adalman grow accustomed to his new un-life), his soul was arranged to be reborn as a demon of the Black Lineage (Diablo's lineage) upon his next death. Upon his demise during the war with the Eastern Empire, he returned in one of the artificial bodies prepared for the demon forces of Tempest, stronger than ever before.
It's Personal: He held his grudge for the Luminaries for over a thousand years, fully intending on wiping them out with the forces of the Empire, and it only ended upon joining Tempest and being reunited with his old friend Adalman.
Undying Loyalty: Played with. Rimuru notes that "loyalty" itself means nothing to him, but rather he treasures the bonds of his dear companions. For his friends' sakes, he would willingly abandon whatever ties of loyalty he has to a nation, but by that same token he would serve faithfully if it served to help those friends.

Kumara

Nine Heads

Voiced by: Sayumi Suzushiro (Japanese)

Originally a small fox spirit enslaved by Clayman as his Thumb Finger, she manipulated Rimuru's good nature to join him in Tempest. Unique among monsters in that every one of her nine tails has a name, giving her unprecedented power and versatility that eventually allowed her to clain the title of Boss of 90th Floor of the Labyrinth. While manipulative of Rimuru's good nature, she is as unfailingly loyal to him as most of his other servants, save for the few that would probably be considered fanatics or the kijin.

All Your Powers Combined: By calling back her tails to her main body, she can use all their abilities with even greater power, but she's limited by both experience in using them all herself and the fact she can only handle using a few powers at once, which is why she prefers to use this tactic for a power-boost at most.
Asian Fox Spirit: All the hallmarks of it, with ancient and modern depictions mixed into both her pre and post evolutions.
Combo Platter Powers: One of the most noticeable examples of this short of Rimuru herself, as each of her separated eight tails/summons has its own powers.
- Mouse (Coccus): Technically several mice, they spread a disease that leaves black spots on the skin and causes a high fever. Not immediately fatal, but only powerful holy magic can heal it and they're so small they're often Beneath Notice in the heat of combat.
- Tiger (Raiko): It controls thunder and lightning while even being wreathed in electricity.
- Rabbit (Getto): It manipulates gravity, and one of her original two summons.
- Snake (Yoda): It's a winged serpent that manipulates the contents of air (like lowering oxygen content).
- Sheep (Mink): It controls the consciousness of others by lulling them to sleep with special hallucinogenic hypnosis. Oftentimes they won't wake back up.
- Ape (Byakuen): It manipulates wind and sound to create storms, as well as creating vaccum blades and wind barriers. It's also physically very strong and wields a staff in combat, while also being one of her original two summons.
- Bird (Enchou): It burns its foes alive with fire.
- Hound (Igami): It reflects enemy attacks back at the caster via a mirror-like ability.
Cute Monster Girl: When she first gains a human form, she looks like a pre-teen as old as the other child Otherworlders. Then she gains power and obtains her adult form, where she graduates to Ms. Fanservice.
Final Boss Preview: In a sense, as each individual tail serves as a guardian for each floor 82nd and above until the final battle with Kumara herself on Floor 90.
Flunky Boss: Her preferred fighting style is to split off her tails save her original (meaning eight at max) and have her summons fight alongside her with their various abilities and teamwork. It's extremely effective and what makes her so dangerous.
Intergenerational Friendship: She becomes good friends with the Summoned Otherworlder children undergoing their mutual training, despite the fact that (despite what her child-like human form would suggest), she was much older than them. It becomes more obvious when she evolves further into a form more befitting her real age.
Kimono Fanservice: Her human form is almost never seen not in a kimono, though it only becomes this in her adult form.
Manipulative Bitch: To a degree. She managed to trick Rimuru into giving her 9 names, but is still unfailingly loyal to him and his goals.
Sleep-Mode Size: When she first appears, she's small enough that Clayman can easily carry her in his arms like a pet. When she steps up to fight Ranga, she grows in size to match him.
Took a Level in Badass: She started out with only three tails, but before being named by Rimuru she had grown four tails. After being named, she immediately grew up to nine tails. She then underwent training alongside Shizue's Otherworlder students under Hakurou and Hinata to gain experience. And then she evolved into a True Demon Lord.
Unskilled, but Strong: Despite her relative young age, only possessing three tails (and thus only two summons), and not even having a name, she was still strong enough to stand as one of Clayman's Five Fingers. She swiftly grew out of the "unskilled" part after coming to Tempest.

Dragon Kings

Zephyrus, Boreas, Notos, Euros

Inferno Dragon King, Frost Dragon King, Thunder Dragon King, Tremor Dragon King

Four Arch Dragons that were captured and tamed by Milim for the Labyrinth, serving as the bosses from Floors 96 to 99. They are explicitly Ramiris' subordinates, even if they do follow Rimuru loyally. They eventually evolve into Dragon Kings from feeding on Veldora's magicules and later still into True Dragon Kings upon receiving names.

Bishōnen Line: After becoming True Dragon Kings, they gain the ability to take human form.
Boss Bonanza: Their effective role is to serve as this for the prospective challengers' lead-up to the Final Battle with Veldora himself, being the back-to-back bosses of the final gauntlet of the toughest levels of the Labyrinth.
Elemental Powers: They cover the spectrum of Fire (Zephyrus), Ice/Water (Boreas), Wind/Lightning (Notos), and Earth (Euros).
Flat Character: Despite being considered among the Labyrinth Lords as well as being sapient, the Dragon Kings don't receive much focus as characters compared to the others.
Homefield Advantage: Each floor is one specifically tailored to an environment the Dragon is aligned with.
- Floor 96 is the Floor of Tremor which is constantly bombarded by earthquakes.
- Floor 97 is the Floor of Storm which is constantly storming with the threat of lightning strikes.
- Floor 98 is the Floor of Blizzard Hell which is so cold death is all but assured without cold-resistant equipment.
- Floor 99 is the Floor of Inferno which is so hot death is all but assured without heat-resistant equipment.
Unskilled, but Strong: Despite their power, they have far less battle experience than the other Lords and tend to prefer just throwing their strength around. This tends to contribute to their defeats in-story.

Labyrinth Staff

Treyni

https://static.tvtropes.org/pmwiki/pub/images/trainee_anime.png

Voiced by: Rie Tanaka (Japanese), Jamie Marchi (English)^{Foreign VAs}

The head dryad of the Jura Forest, and one of the most powerful allies Tempest has in the early part of the story, as the dryads have the power over the forest itself. She asks Rimuru to deal with the orcs, seeing them as a threat to the forest and its inhabitants in general. She later eagerly becomes Ramiris' subordinate.

Big Eater: She has an utterly massive appetite that she takes every possible opportunity to sate, with the majority of scenes she appears in having her scarfing down bowl after bowl of potato chips.
Brilliant, but Lazy: She's a powerful dryad who is quite effective at acting as the adminstrator of Jura Forest, but she greatly desires to just laze around and eat potato chips, and she takes every opportunity she can to trick other people into taking up her duties while she sneaks away to do just that. It eventually reaches the point that her sisters basically have to literally tie her up and drag her around just to make sure she actually does her duties.
Demoted to Extra: Despite having a decently important role as the main caretaker of the Jura Forest and thus working very closely with Rimuru as Tempest is developed into a thriving community and country, she more or less falls off to the wayside past the Orc Disaster incident in the main story. It's up to the point The Slime Diaries makes fun of this by having Rimuru completely forget that Treyni would be perfect for and enjoy the community-wide farming event in Episode 2, which leads her to sulk and passive-aggressively guilt-trip him at the episode's end.
Earthy Barefoot Character: Certain quick frames show that she never wears shoes no matter where she goes, representing her status as a Nature Spirit with a strong connection to the earth.
Elemental Hair Colors: She's a plant-controlling dryad with green hair.
Eyes Always Shut: She's usually depicted with her eyes closed. Them being open is usually a sign she's either angry and ready to fight, or being serious about something.
Got Volunteered: She has a habit of volunteering Rimuru to high ranking positions. Rimuru suspects that despite her being the one to have the higher authority, she just doesn't want to do it.
Green Thumb: She's a dryad, so it's kind of a given that she'd be able to control plants.
Nature Spirit: As a dryad, she's a decently strong holy spirit whose purpose is to both manage and safekeep the forest she was born from. She's also part Plant Person because her true body is a sentient magical tree.
Phosphor-Essence: Her body usually glows with a greenish aura.
Plant Person: She's a dryad, which in this world is a Nature Spirit born from a magical tree called a "dryas". A caveat to this is that her existence is tied to said tree and can't go far beyond the Forest of Jura where it was grown from. She and Rimuru eventually figure out a workaround for this conundrum when they decide to have her come to Walpurgis with Ramiris by carving a magic doll out of the wood from her true body and have her spirit possess it to become a Dryas Doll, similar in nature to Berreta becoming an Arch Doll, which not only allows her freedom to go anywhere she wants but also turns her into a physically literal plant person.
Trademark Favorite Food: She can't go a chapter in the spin-offs without asking for some potato chips.
Yes-Man: To Ramiris, to the point that Rimuru is glad that Beretta is with them since his own Undying Loyalty won't stop him from trying to dissuade Ramiris from something stupid, while Treyni will support it no matter what.

Ifrit/Charys

Flame Lord

Voiced by: Taku Yashiro (Japanese), Chris Guerrero (English)

https://static.tvtropes.org/pmwiki/pub/images/ifrit_anime.png

The being inhabiting Shizu, a flame spirit called forth by Leon with a taste for death and destruction. Originally contained by Shizu using both her mask and willpower, they eventually break free and try to resume their desires, only to be thwarted by Rimuru. They eventually form a friendship with Veldora, who convinces Rimuru to give them a new body, following which they're given the name "Charys".

Call a Pegasus a "Hippogriff": Though fire-related, in mythology an Ifrit is a type of genie rather than a giant or titan.
Defeat Means Friendship: After being devoured by Rimuru, they're spared by Veldora due to being bored and wanting someone to talk to. The two end up striking up a friendship, and Veldora eventually convinces Rimuru to give them a body to serve as his assistant, Veldora even naming them "Charys".
Doppelgänger Attack: Ifrit can summon copies of themself made of fire to overwhelm the opposition.
Enemy Summoner: Ifrit can summon Salamander demons to aid them in battle, which breathe fire and can explode violently.
Evil Is Burning Hot: They don't just have the ability to manipulate flames, their very body constantly produces intense heat, enough to melt rock just by touching it. Subverted after befriending Veldora, since not only are they not evil anymore, their raging fiery aura gets tempered.
Fiery Salamander: Can summon salamanders in battle.
Flat Character: After their introduction and absorption by Rimuru, they spend a large majority of the story having their The Stoic status be practically their entire personality, with only a tinge of Hidden Depths revealed over time. When they finally start getting some Character Focus, it turns out this caused major issues for them, because the lack of ambition and poor sense of self prevented them from developing skills and getting stronger, to the point the Harvest Festival completely passed them over for skill upgrades because they had no personal growth to capitalize on for power-boosting.
Heel–Face Turn: After being devoured by Rimuru and bonding with Veldora, they are given a new body and a name, while swearing to serve Veldora.
Hidden Depths: While initially portrayed as a Generic Doomsday Villain beast - "Tales: Veldora's Journal" reveals they're secretly an Affably Evil Noble Demon, even regretting the pain their possession caused Shizue.
Instant Runes: Can create a magic circle without chanting.
Meaningful Rename: Ifrit is named "Charys" by Veldora, owing to their new body being formed from Charybdis' magical core.
Oh, Crap!: Ifrit gets several when they realizes their flames don't work on Rimuru, but their biggest is when they sees Veldora after they're devoured by Rimuru's Predator skill.
Otherworldly and Sexually Ambiguous: Just like with demons, while Ifrit possesses a masculine appearance, being a spirit means they technically have No Biological Sex, and they don't even have a specific gender identity like the progenitors and Beretta.
Playing with Fire: As the one that provides Shizu with her power, they go even further with it than her, having a variety of techniques involving the manipulation of flame.
Scissors Cuts Rock: Ifrit and their Salamander summons' flames are so intense that Rimuru attempting to use Water Blade on them just causes it to erupt into steam without effect, and Great Sage informs him that while if he unleashed all the water in his body at once he could overpower it, the resulting explosion of steam would take out the entire goblin village in the process. This forces Rimuru to rely on using ice magic and his own immunity to flame to win.
The Stoic: Their normal expression is an indifferent grimace, with most of their fight only having them change expression when casting magic. That said, dealing with Rimuru and then Veldora causes them to lose their composure, expressing shock and fear.
Took a Level in Badass: Being named by Veldora boosted Ifrit/Charys' power to beyond that of Carrion and Frey to a level comparable to True Demon Lord.
Undying Loyalty: To Leon Cromwell, with Ifrit admitting they were a loyal subordinate to the Demon Lord and it was why they obeyed his command to possess Shizu. They also admit it was because they were loyal and Shizu wasn't due to her personal issues and hatred of Leon that they had such bad compatibility.

Beretta

Guardian of Ramiris

Voiced by: Ayako Kawasumi (Japanese), Morgan Garrett (English)^{Foreign VAs}

A former Greater Demon that Rimuru summoned and bound to a Golem of his creation to serve as a guardian for Ramiris in exchange for her help. While ostensibly "on loan" to Ramiris for a few centuries before he would transfer his loyalties to Rimuru solely, events and Beretta's growing fondness for the pixie leads to him becoming Ramiris' servant full-time.

Actor Allusion: In the anime, when Beretta is soaking in the women's hot springs his hair is up in a Prim and Proper Bun very similar to one of the most well-known roles of Ayako Kawasumi.
Berserk Button: He considers his mask his prized possession since Rimuru gifted it to him and told him to always wear it, so anybody who hits the mask will drive him into a murderous fury. One point in the novel has him get into a fight that outright results in the mask breaking, which understandably put him in an Unstoppable Rage that causes him to go on a brutal rampage.
Conflicting Loyalty: He understands this is a very real risk should Ramiris and Rimuru become hostile to each other, so he endeavors to fix this by ensuring they don't have a reason to come to blows.
Curb-Stomp Battle: His 'fight' with Clayman's doll Viola has him complimenting her versatility and mocking her low offensive power, while she is impaled and dying on his blades. In the anime, it isn't even shown and flat-out cuts to him having already taken Viola apart and now procuring spoils of war from her body while neatly arranging her parts out.
Extra-ore-dinary: After evolving into a Chaos Metalloid via Rimuru's Harvest Festival post-the Empire War, Beretta gains the Ultimate Skill Deus Ex Machina, Lord of Machine God, which grants him Mineral Domination and Control Earth to manipulate any non-supernaturally enhanced metal to his liking. This also includes his own now-Hihi'irokane body to the point of Voluntary Shapeshifting.
The Faceless: What appears to be a monstrous doll head is actually a mask he wears to conceal every part of his head besides his long hair. The story also is very adamant about him always wearing it, which the novel explains is because Rimuru found his face so stunningly beautiful that he adamantly ordered Beretta to put on the mask and never take it off, meaning he refuses to expose his face unless somebody outright forces it off him, something that happens later in the story to his fury.
Noble Demon: Literally, as he holds a deep sense of loyalty to the masters he respects and wants nothing more than to help them to the best of his ability. This is eventually proven to be a standard trait for all "Black" demons, as demonstrated by the Black Progenitor, and Berreta's superior in hell, Diablo.
Odd Name Out: As he was summoned and named before Rimuru settled on the Vehicular Theme Naming he would give to the demons, "Beretta" is the only one not named after a sports car but rather the Berreta gun brand (though it's also fitting since he's the odd one out of said demons, being bound to a golem rather than a homunculus body).
Only Sane Man: Despite his Undying Loyalty to Ramiris, he's not blind to her eccentric nature and finds himself being run ragged trying to keep her reined in. Things get better/worse for him once Treyni shows up, since Treyni despite her reliablity is also Ramiris' Yes-Man.
Our Demons Are Different: He's a demon bound to a powerful Golem made by Rimuru. The golem is now his body and technically changed his race to an "Arch Doll" (which would be the technical equivalent of an Arch Demon), and it can even evolve as if it were a flesh-and-blood form.
Took a Level in Badass: He was already powerful thanks to his own strength alongside that of the golem body made for him, but since Rimuru was still technically his master at the time he also received a power boost from the Demon Lord ascension and evolved into a Chaos Doll. Guy even pegged him as at least as strong as Shion and Ranga post their own power-ups at the Walpurgis Banquet.
Undying Loyalty: To both Ramiris and Rimuru. His on-board desire to see Ramiris move to Tempest is to ensure that he'll minimize the chances of Conflicting Loyalty while also getting to work with both of them.
Vocal Dissonance: Played with. Ayako Kawasumi plays Beretta with a calm, soft feminine voice that fits his appearance as a long-haired, thin and technically sexless Golem, but is rather out of place when remembering his bigger, muscular, and more masculine-looking Greater Demon form before he possessed the doll.
Yin-Yang Bomb: His Unique Skill [Reverser] allows him to obtain and use two diametrically opposed essences at once without consequences, letting him invoke this trope at will. In his case, he uses both demonic and angelic essences together.

Tempest Allies

Youm Farmenas

Champion

https://static.tvtropes.org/pmwiki/pub/images/youmanime.png

Voiced by: Yoshimasa Hosoya (Japanese), David Matranga (English)^{Foreign VAs}

A warrior who initially encountered Rimuru after the Orc Disaster incident after being sent by Count Nidol Migam of the Kingdom of Falmuth to investigate, and also brought his assigned party to heel through force and charisma to free himself of the magically-binding contract he was under. He ended up joining forces with Tempest and taking credit for defeating the Orc Disaster while becoming a staunch ally of the monster kingdom.

Ain't Too Proud to Beg: When Myulan's involvement with the attack on Tempest was discovered and her punishment to be decided, Youm does not hesitate to beg Rimuru to spare the Majin, reasoning that she only did what she did because she was unable to go against Clayman's orders. When Rimuru decided that Myulan needed to die, Youm frantically begs for her life to be spared, even fully prepared to be punished alongside her. Fortunately, Rimuru doesn't actually kill Myulan and just intended to replace her bugged heart with a new one.
Awesome Moment of Crowning: He becomes the King of the Farmenas Kingdom, forged out of the destroyed remnants of the Kingdom of Falmuth after the "war" with Tempest.
Badass Normal: Thanks to Hakurou's training and some high-level enchanted gear, he can match the fighting prowess of a high-ranking beastman like Grucius.
Becoming the Mask: Enforced. He was selected by Rimuru to pose as the one who slew the Orc Disaster in order for him to put out the good word about how he was helped by the country of Tempest. In order to make his status more believable, he undergoes training under Hakurou.
Face of a Thug: His rough looks hide his good heart.
Fake Ultimate Hero: Tempest gave him credit for killing the Orc Disaster despite not even being in Tempest during the attack. They do make sure to train Youm up so he actually fits the part.
Friendly Rivalry: He strikes up an Interspecies Friendship with Grucius of the Beast Kingdom Yuurazania, with the two of them becoming sparring partners and rivals for the affection of Myulan.
Interspecies Romance: With Myulan, with him being an otherwise normal human warrior while she's a centuries-old Majin.
Master Swordsman: He was decent with a blade at first, but then he got lessons from Hakurou and truly became this.
Oh, Crap!: His reaction when Fuse drops the bomb that every one of the over 10,000 monsters in the village they are currently in the center of is a named monster (and thus the village is powerful enough to wipe a nation off the map).
Puppet King: He knows full well that his status as the future king of Falmuth is just a formality, with the true ruler being Rimuru, but since peace and prosperity will come to his kingdom through that arrangement, he doesn't mind it much.
Seen It All: The only reason he is composed when seeing and being introduced to Veldora, a Catastrophe class monster is likely due to already having experience with Milim, another Catastrophe Monster.
This Is Gonna Suck: Any time Hakurou calls him for training, he understandably feels this way.
Took a Level in Badass: Boy did he ever! Between Hakurou's brutal training and the Tempest forged gear he received he has quickly grown to the point where he can match high tier Majin in fair combat.
Undying Loyalty: Towards Rimuru, like almost everyone else on this page. He was only willing to become the king of Farmenus (formerly Falmuth) because Rimuru asked him to.
You Have GOT to Be Kidding Me!: The first time he sees Veldora, this is his response.

Myulan

The Ring Finger

Voiced by: Atsumi Tanezaki (Japanese), Colleen Clinkenbeard (English)^{Foreign VAs}

One of the Five Fingers under Great Demon Lord Clayman, Myulan is a Majin that disguised herself as a human and went under the employ of Tempest to serve her master's ends. However, she started having doubts after witnessing Tempest's prosperity and falling in love with a human named Youm.

Barrier Maiden: Alongside Shuna, it's her job to preserve the souls of Tempest's fallen during the "war" with Falmuth with her magic long enough for Rimuru to ascend to True Demon Lord status and properly revive them.
Easily Forgiven: Actually a bit defied when it comes to her involvement in the slaughter of Tempest City, most notably Shion. While the only thing she contributed was the small role of disabling telepathy so Rimuru would arrive too late to help, it was still a major factor in Tempest falling under major harm. As such, the only person willing to speak up for and try to ask forgiveness for her actions was her lover Youm, whereas everybody else, even Rimuru, hated her enough to want to kill her. It's only once the full reasoning behind why she helped facillitate to slaughter of Tempest and her wholeheartedly giving her everything in helping right what wrong she did by way of safeguarding every dead person's soul so they could be revived that everybody finally forgives and welcomes her back.
Face Death with Dignity: When Rimuru decides that she needed to die because of her involvement on the attack on Tempest, she calmly accepts her fate. She simply confesses her love to Youm and told him to not be deceived by evil women again. Fortunately, Rimuru has other plans for her.
Game Face: Myulan normally looks like a beautiful young woman with green hair and blue eyes, but when she reveals her true Majin form she gets a Third Eye, various tattoos, clawed hands, and fur growing on her body, albeit still beautiful in her own way.
Hard-Drinking Party Girl: Only really showin in the manga, but she can down large mugs of alcoholic drinks without ever getting tipsy, and that is the first thing that she went to during the festival that followed Rimuru's awakening as a True Demon Lord.
Literal Change of Heart: Rimuru replaces the flawed, bugged heart Clayman used to keep tabs on her with a magical artificial heart, though by then Myulan already regretted her actions.
Please Kill Me if It Satisfies You: Rimuru suspects that Myulan was attempting to goad him into killing her in order to spare Youm and Grucius from being punished for protecting her. While he seriously considers doing so after seeing how many were killed, Great Sage informs him that Myulan's anti-magic barrier wasn't the primary cause of the Tempest citizens being weakened and Myulan herself reveals she was an unwilling pawn of Clayman, prompting him to pardon her.
Really 700 Years Old: She literally is over seven hundred years old, making her romance with Youm a Mayfly–December Romance.
Regretful Traitor: Though she was always a spy, Myulan isn't happy about helping the Kingdom of Falmuth slaughter Tempest after staying there for a time and needs to be further blackmailed by Clayman to go through with it. In fact, after the whole debacle and Rimuru forgiving her part in it she becomes a staunch advocate of preventing such a thing from happening again.
She Cleans Up Nicely: After marrying Yohm and becoming queen, she reveals she had all the decorum of one due to Clayman insisting that his subordinates have at least some measure of class, and she needed it more for her underhanded dealings. Clayman proved to be surprisingly useful in preparing her for her new role as queen.
Was Once a Man: She was once a relatively normal witch who lived about 300 years and was dying of old age when Clayman found her. When he offered her a new lease on life and she accepted, she transformed into a Majin but in exchange became bound to him via [Marionette Heart]. He noted that even if she did somehow remove the heart, she would just revert back to her old age and die shortly afterwards, and regardless, she wasn't nearly strong enough to defeat him in a straight fight anyway.
What Is This Thing You Call "Love"?: Myulan admits in all her long life she's never experienced real love, which is why her feelings for Youm and his declaration of his own for her takes her by surprise so badly.

Various citizens of Tempest

Koby

Kobold Merchent

Voiced by: Taito Ban (Japanese), Travis Mullenix (English)^{Foreign VAs}

https://static.tvtropes.org/pmwiki/pub/images/koby_tensura.png

A Kobold that serves Rimuru as a merchant to and from their various allies.

Beast Man: He is a kobold, which like most Japanese fantasy stories means he has the appearance of a humanoid canine.
A Lizard Named "Liz": He's a kobold named Koby.
Non-Action Guy: As a merchant who wasn't named by Rimuru, he's among the few people who interacts with Tempest yet has absolutely zero combat capability, and is understandably constantly at his wits' end interacting with countless absurdly strong monsters.
Quaking with Fear: He was more than a little scared to do business in the Animal Kingdom, due to them normally not allowing weak monsters.
