Shizue Izawa
Shizue Izawa
Explosive Monarch
Another human reincarnated into this world from the Tokyo Firebombings of World War II, she is a Summon who houses the soul of the Fire Giant, Ifrit, and bears a deep connection to Rimuru's fate...
- Broken Ace: Shizu became a hero spoken of as "The Explosive Monarch" and did plenty of good in her life fighting monsters, saving lives, and trying to help fellow Otherworlders where she found them. She was also deep down a woman who hated the world she was summoned into because it separated her from her mother and hated herself for possessing the power of Ifrit, since she periodically lost control and killed people she cared about. It's telling that when she dies, her Dying Dream involves her reuniting with her mother while reverting back to her childhood self.
- Cast from Lifespan: Overexerting her magic fighting a dragon caused her to age, though to be fair she is in her 70s-80s even if she appears otherwise.
- Cool Teacher: Actually the only one able to keep the Summons class in the Freedom Academy at Incracia in check. At least until Rimuru took over.
- Covered in Scars: Under her clothes she still has the burns from her summoning, and she only survived them because Leon had Ifrit possess her.
- Cursed with Awesome: She suspects her youth might be a curse from the demon lord but is happy with it.
- Cute Ghost Girl: While she's still very much dead and nobody can see her, she periodically makes appearances in The Slime Diaries from the afterlife. In episode 8 she straight up walked among the living since there was a festival with a "spirits will visit the living" belief that becomes literal in this world, while the rest of the time she simply looks out from Heaven to comment on things. As she can't actually interact with the living anymore, she frequently watches as her friends do things that tarnish her name and memory in harmless but embarrassing ways, such as seeing Rimuru running around wearing a bunny suit with her appearance or the Blumund trio being distracted from her memory by other things.
- A Day in the Limelight: The anime has the entirety of episode 24 be dedicated to one of her past adventures, specifically detailing her meeting with the demon that would eventually be named "Diablo".
- Death by Origin Story: Her character is basically there to die and in the process give Rimuru a human form, along with a few plot threads like Leon Cromwell and the children in Ingracia. The light novel and further adaptations flesh her out a bit more, but the basics remain the same.
- Demonic Possession:
- When Ifrit originally took her over, he used her body as a vessel, but she was eventually able to take back control thanks to a hero and the use of her Anti-Demon Mask. However, recently, Ifrit began to regain strength thanks to her own own dwindling lifespan, and ultimately she falls back under it and forced to fight Rimuru. However, it should be noted that Leon did this specifically to extend her lifespan, as she wouldn't have survived the burns from her summoning otherwise.
- The manga also changes the nature of the possession to a minor extent. In the manga, Shizue completely lost herself to Ifrit upon her original possession and only regained herself thanks to being defeated by a hero and gaining her mask. In the anime/light novel, Shizune had more control, but Ifrit could usurp her against her will if he sensed a threat in Leon's presence. The amount of time she could go without wearing the mask without risking losing herself again to Ifrit is also much smaller in the manga.
- Fish out of Temporal Water: Played with in that she never made it back to Earth, but as a denizen of World War II era Japan she finds herself astonished when Otherworlders from the more modern era arrive and tell/show her how society has changed since. ISEKAI Memories reveals in the "Always My Valentine" event that she never knew about Valentine's Day until her students told her about it, and at one point she sees clothing from modern-day Japan and is amazed when she reads the price tag that says it's over 5000 Yen, as from her time that would be a fortune.
- Flaming Sword: One of her preferred tactics is to wreathe her blade in fire to increase its destructive power.
- Fusion Dance: Not only is she merged with the Superior Spirit of Flame Ifrit, Shizue's Unique Skill [Degenerate] has the ability to combine and disassemble Skills and other objects in her possession at her whim, which gives her incredible versality. Indeed, it was the use of [Degenerate] that prevented their proper fusion into a full majin. When Rimuru and Great Sage obtain the Skill after absorbing her, it quickly becomes the bread and butter of the latter's arsenal to forming new Skills and abilities.
- I Just Want to Be Normal: Shizu hated the power given to her by Ifrit's possession due to what she did without control. As a result, she forcibly suppressed Ifrit's influence first chance she got, and she refused to extend her lifespan further by becoming a majin because she wanted to someday die as a human.
- I'm Having Soul Pains: Due to the fact that Ifrit is slowly starting to regain control as her life nears its end.
- In-Series Nickname: "Shizu," which was originally coined by her summoner after she told him her name as "Shizu...e" and he took it as "Shizu E."
- The Lost Lenore: To Rimuru. While it is unknown if he had romantic feelings for her, her death left a significant impact on him as he swore to take care of the summoned children that she taught and confront Leon Cromwell for his actions towards her, to the point that her body is the form he morphs into when he wants to take a human shape... albeit with a few color changes.
- Mask of Power: Her Cool Mask isn't just for show, it has anti-demon properties which helps her suppress Ifrit's influence on her mind and body. Rimuru eventually takes it as a Memento MacGuffin.
- Mind-Control Eyes: When they turn glowing red, that's when Ifrit starts taking over Shizue's mind.
- My God, What Have I Done?: Had a really bad one in the past when Ifrit took her over and made her torch her fellow child friend and her monster pet to ashes, whereupon the latter had viewed said pet as a threat to Leon. (Anime/Light novel only; in the manga, once Ifrit is inside her she doesn't regain control for quite some time.)
- Oh, Crap!: Shizue has one every time Ifrit starts taking her over.
- Older Than She Looks: She was reincarnated during World War II as a child, which would put her in her 70s to 80s, but she still looks barely over her mid-20s at latest. This actually helps her keep up a disguise along with her nickname of Shizu, as none of her fellow adventurers realize that she's actually the retired hero known as "The Explosive Monarch." Once she passes on, her body's appearance changes to one that's more fitting of her actual age.
- Playing with Fire: Gains this as a result of her possession by Ifrit.
- Posthumous Character: Most of her character comes about after she passes on/is absorbed by Rimuru, but there's still enough when she's alive for Rimuru and the audience to be sympathetic to her plight.
- Red Baron: When going by her real name of Shizue Izawa, she was known throughout the land as the "Conquerer of Flames", both because she had the flame spirit Ifrit possessing her, and because she maintained control over the spirit and utilized it's fiery powers to help others.
- Retired Badass: She's apparently been retired for 50 years according to the adventurers.
- Revenge: She hates Leon Cromwell for summoning her half-dead from flames, having Ifrit take over her body, and then abandoning her to fight a hero as a sacrificial pawn. Her desired goal before dying was to find and hurt him for all of it, and asks Rimuru to do the job for her as part of her Last Request. Of course, the truth is a bit more complicated than that...
- Scars Are Forever: Magic can't heal her burn scars because merging with Ifrit stabilized her body to its current state.
- Spit Take: Did one when Rimuru said he wasn't a bad slime because it reminded her of Yuuki talking about Dragon Quest.
- Together in Death: Gets reunited with her mother once she finally passes.
- Transformation of the Possessed: Happens to her when she fully loses control of Ifrit. She goes back to normal when Rimuru uses Predator on him and thus separates them.
- Wizards Live Longer: Stopped aging at 16 or 17 thanks to either Ifrit or Leon. She could have lived even longer if she chose to become a majin, but Leon notes she wanted to keep what humanity she still had and refused.
- Your Days Are Numbered: Despite her youthful appearance, Shizu is quite old, in her 70s at best, and is at the end of her life. She left her retirement to exact her revenge on Leon Cromwell for summoning her from her original world, but her trip was cut short as she had no more strength to contain Ifrit possessing her. Though Rimuru ended up beating the fire spirit quite handily, thus freeing Shizu, the strain of combat was too much for her (not to mention Ifrit actually keeping her alive all that time) and she died soon after the fight. Leon states long after the fact that she could have extended her life even further by becoming a majin, but she wanted to die as a human.
- You Will Be Assimilated: On her deathbed, she tells Rimuru to absorb her using [Predator] to gain her powers and fulfill her Last Requests (to save the summoned children and to take revenge on Leon for her). Rimuru doing so is what allows him to regain a human form at last, which looks like a younger blue-haired, golden-eyed version of Shizue herself.
Summoned Children
The Summoned Children in General
A group of five small children who, like Shizu, were summoned in order to turn into Heroes. However, because the process of summoning has some unforeseen consequences, the children now only have a few years left to live.
It is Rimuru's mission now to help the children move past their life expectancy, as Shizu's last desire.
- Always Second Best: All of them are this to Chloe, but it's most noticeable with Kenya. Unlike the others, who merged with Superior Spirits Rimuru created from fusing multiple minor spirits together, Kenya bonded with the Spirit of Light who outright blesses Heroes with divine protection and told him he has the potential to be a Hero just like Shizu, and he's one of the most skilled swordsmen of the bunch after his training. Unfortunately for him, Chloe merged with her future self that's basically a demigod, he self-admits she's a better swordsman over him, and she's the True Hero.
- Elemental Powers: Due to the fact that they are fused to various Superior Spirits, they gain powers related to the specific element that the spirits possess:
- Kenya: Light 'em Up
- Ryota: Making a Splash & Blow You Away
- Gale: Dishing Out Dirt
- Five-Man Band: They're a group of five young potential Heroes.
- Fusion Dance: Power Booster variation. They all go through this in order to stabilize their magicule levels with Superior Spirits.
- Guardian Entity. The Superior Spirits they are fused to function as this, as they increase the Summon Children's power.
- Heroic RRoD: The origin of their shortened lifespans. Summoned Otherworlders have an immense number of magicules but children do not usually inherit the Unique Skills necessary to put them to sufficient use. Pair that with the strain of containing such power on an immature body and children summoned to the Otherworld will eventually have their bodies destroyed due to their own power.
- Magic Knight: They become this thanks to their training under Rimuru, Hakurou, and Hinata, becoming equally versed in using weapons as much as their Skills and magic.
- Magical Girl Warrior: In the ISEKAI Memories event "Princesses of the Inner Peace", Alice and Chloe are tricked into buying a set of earrings from a shopkeeper that turn out to be a sentient Transformation Trinket named "Tiahier" that, once they trigger the Transformation Sequence, put them into matching sets of Cursed Armor in the vein of magical girls that raise the stress levels of anyone around them to murderous levels while providing magic swords that cut a person's spiritual body to "slice" off the excess stress to return them to normal. In addition to being embarrassed by the outfits, however, they quickly realize they can't remove the outfits normally and it quickly starts causing trouble when the curse starts affecting the city guards, the monsters outside the city, and even their fellow classmates. This was All According to Plan to the shopkeeper, who is actually the incarnated spiritual being form of the earrings named Carbuncle (similar to the relationship dryads like Treyni have with their avatars and true tree forms) who condenses and crystalizes the cut-off stress into stones that she uses to make more cursed magical artifacts, which she sells off again to repeat the process to get rich, grow more powerful, and maintain her incarnated spiritual body to move about freely. The reason she especially chose Alice and Chloe is because their innate potential makes them some of the few powerful enough to use the Cursed Armor to its full potential.
- Master Swordsman: Kenya is the straightest example of the bunch since he's the one who mainly relies on a sword, but all of them have some swordsmanship skills at their disposal.
- More than Mind Control: During the ISEKAI Memories event "Princesses of the Inner Peace", Kenya, Ryoto, and Gale all end up being affected by Alice and Chloe's cursed Magical Girl Warrior armor raising their stress levels and bringing out their inner frustrations to the surface, but unlike the guards and magical beasts that were rendered Brainwashed and Crazy by their stress levels going out of control and reduced to more or less attacking in blind rages, they're able to harness the boosts effectively and give Chloe, Alice, Ranga, and Rimuru a decent fight.
- Sharing a Body: All of them are this thanks to being fused with Superior Spirits, and even have the ability to communicate with them to some extent.
- Teacher/Student Romance: Alice is implied to have feelings for Rimuru at first, but she seems to get over them as the story hints she's growing a thing for Kenya. Chloe, on the other hand...
- Two Girls to a Team: Chloe and Alice are the only girls in the class, with the rest being boys.
- Your Days Are Numbered: When Rimuru first meets them they only have a few years left to live, since the magicules in their bodies will eventually collapse if nothing is done about them. This ceases to be an issue once Rimuru and Ramiris stabilize them with the power of spirits.
Kenya Misaki
One of the five Summoned Otherworlder children taught by Shizue Izawa. He is shown to be the unofficial leader of the Class S children and one of the kids who was most mistrustful of Rimuru upon meeting him.
- Affectionate Nickname: His friends affectionately call him "Ken".
- Awesome, but Impractical: Kenya has a habit of doing this. When Rimuru first mock-battled him, he had a habit of using flashy attacks with long windups that wasted his energy when they missed. Even after he gets proper training, he starts incorporating moves from various manga into his swordsmanship that look cool or have Confusion Fu style tricks, but they use overextending movements and have openings a quick enough foe could easily take advantage of.
- Elemental Hair Colors: He has orange hair and his preferred magic is to use fire-based attacks, like Shizu.
- Elemental Personalities: He's the Fiery Redhead of the group and has fire powers.
- Fiery Redhead: He's a Hot-Blooded redheaded boy.
- Hot-Blooded: He's energetic and impulsive.
- The Leader: He is considered the unofficial leader of the group, which is further enhanced when he gets his spirit which marks him as a potential Hero.
- Light Is Good: His possession of the Spirit of Light showcases that he has the possibility to become a Hero in the future.
- Playing with Fire: Kenya's introduction involves him launching a flaming Sword Beam at Rimuru the moment he enters S-Class, and complaining that he missed. Rimuru is quick to note that he tends to just throw fire around, however, and that his flames aren't anywhere in the ballpark to Shizue's.
- Puppy Love: It's heavily implied that Kenya has a crush on Alice, though he only knows how to express himself by challenging her to fights.
- Spiky Hair: He has spiky orange hair, befitting his Hot-Blooded status.
Ryota Sekiguchi
One of the five Summoned Otherworlder children taught by Shizue Izawa.
- Aloof Archer: His weapon of choice is a bow, and he's a calm and calculated charcter when not being The Berserker.
- The Berserker: Ryouta Sekiguchi is usually quiet and timid, but his special ability sends him into an animalistic berserk state where he runs on all fours, clawing and biting at his opponents.
- The Lancer: He's stoic and shy compared to the Hot-Blooded Kenya.
- Making a Splash: Ryouta after he receives training is able to use water magic as well, combining it with wind magic for impressive combos.
- Power Stereotype Flip: Most characters with The Berserker as a fighting style have a Hot-Blooded personality with a Blood Knight attitude, but Ryota is a timid and quiet boy who normally balks at fighting. However, given how [Berserker] is his Unique Skill, which are acquired based on the true thoughts and feelings of the owner, this implies that beneath the calm and quiet personality is a well of Suppressed Rage.
- The Quiet One: Unlike the Hot-Blooded Kenya, Ryouta is shown to be more quiet and passive.
Gale Gibson
One of the five Summoned Otherworlder children taught by Shizue Izawa.
- Alliterative Name: Gale Gibson.
- Big Brother Instinct: When Gale and the others visited the Dwelling of the Spirits, he asked Rimuru to take care of the other summoned chidlren if anything were to happen to him.
- Dishing Out Dirt: Gale is able to manipulate earth's structure and composition, allowing him to make it as hard as steel. It's noted it's actually very useful for agricultural purposes.
- Fish out of Water: It's implied that Gibsons' not originally from Japan when he was summoned, meaning that many of the customs and mannerisms employed by other Japanese Summons are unfamiliar to him.
- Hand Blast: Gale showed the ability to fire powerful magic bullets from his hands.
- Luckily, My Shield Will Protect Me: He wields a shield, which he uses mainly to defend himself and his allies from attack.
- The Smart Guy: He's the oldest and wisest member of the group.
- Summon Magic: After obtaining his Superior Spirit and training with it, he has shown the ability to summon a earth spirit named Beast Gnome.
Alice Rondo
One of the five Summoned Otherworlder children taught by Shizue Izawa.
- Girls Love Stuffed Animals: Alice has trio of stuffed animals that she is shown to be fond of. She can also animate them via her powers.
- Marionette Master: Alice is able to levitate and manipulate dolls. Rimuru thinks to himself that she would be more effective if these dolls had claws, or if she could control other tougher stuff. After her training, that's exactly what she does by not only switching up for metal dolls armed with various weapons, but she can also suspend a number of swords in the air to launch as a Storm of Blades or control telekinetically.
- Ojou: While it is unknown if she comes from a wealthy family, she has all of the mannerisms and behavior of one. After she gets her training, she starts to insist she be called "Empress" by her fellow children.
- Space Master: She can manipulate the Spacial element due to her spirit.
- Spoiled Sweet: Despite her haughty demeanor, she is shown to be quite kind and caring towards her friends and people who have earned her trust like Rimuru.
- Storm of Blades: After obtaining her Superior Spirit and training with it, she showed the ability to levitate and control a large number of small blades, which she can use to attack others at a distance.
Chloe Aubert (MASSIVE UNMARKED SPOILERS)
Chloe Aubert
Hero Chronoa
Click here to see Chloe as Chronoa
One of the five Summoned Otherworlder children taught by Shizue Izawa, Chloe at first seems to merely be a girl with notable talents even among them. In reality, she was/is/will be a True Hero responsible for many notable feats in the backstory of the setting, all in her goal to save Rimuru Tempest from a horrible fate...
- Affectionate Nickname: Her friends affectionately call her "Chlo".
- Beware the Nice Ones: Crosses over with Beware the Quiet Ones as well. Chloe is usually a kind quiet girl who is slow to anger compared to Alice. When she actually does get angry, her friends are all in agreement she's the scariest of them, and she legitimately frightened Rimuru during their mock battle by how calmly ruthless she got about using the water-blade-prison spell as a threat if he didn't surrender. That's even all before she becomes the World's Best Warrior.
- The Big Girl: She's the most talented and strongest member of the group.
- Childhood Friends: Chloe is one for Leon Cromwell. Specifically, when they were both caught up in the Summoning, she ended getting caught in a time distortion that sent her to the future, leaving him desperate to try and find her.
- Cuteness Proximity: Rimuru's slime form is this to her. She outright calls him cute when he is in her arms.
- Deity of Human Origin: Chloe's future self — who travels back in time to stabilize her child-self — is a Demigod, a divine entity surpassing both Heroes and Sages. Ramiris is terrified of her, though she does little more than kiss Rimuru and empower her past self.
- Fusion Dance: Compared to the other Summoned Children, Chloe and her future self take this a step further when they fully fuse, allowing Chloe full access to her future self's powers and memories (up to the ability to assume her adult form) while also being influenced by her personality.
- Future Badass: Both this and Precursor Heroes as well due to some Timey-Wimey Ball shenanigans. Chloe as she is in the present is a powerful fighter but still an inexperienced child with a lot to learn. Her adult self is so powerful she can challenge some of the strongest beings in the world and have a shot at winning.
- Heroic RRoD: During her fight with the Single-Digit Imperial Guardian Jiwu in Volume 13, Chloe attempts to use her Time Stands Still power to catch her Combat Pragmatist opponent, but she pushes the duration of the time stop for too long and, due to her inexperience in using [Yog Sothoth] actively rather than reflexively as she did in her mock fight with Guy, she burns up too much power and reverts to her child form from the strain, and to add insult to injury she still didn't catch Jiwu before the time stop ran out. When Raphael gives her a shot of energy and some help, she's able to power through and take Jiwu down with the next attempt.
- Identical Stranger: It's not directly commented upon, but Chloe has a lot of similar traits to Shizue, specifically longish black hair and blue eyes. It's heavily implied it was these shared traits that resulted in Shizue even being summoned in the first place, as Leon had been keying his summonings to specific triggers to try and summon Chloe specifically.
- Making a Splash: Chloe can control water to such a degree she can trap people in a sphere of swirling water and then form blades in said water to slice her victims apart.
- Master Swordsman: All of the children get at least some swordsmanship training to varying degrees of proficiency, but Chloe is the standout. Her skills with the sword improve so much Hakurou and Hinata both believe she will surpass them with time. She's also able to deflect a surprise attack by Guy while in a sitting position after she's merged with Chronoa, and subsequently parry all of his probing slashes before Rimuru steps in between them.
- My Future Self and Me: Chloe is indwelled by the time-travelling divine spirit of her future self, which according to Ramiris creates a time loop. Specifically, "future" Chloe is a Manas called "Chronoa" that is the result of Chloe constantly trying (and failing) to save her loved ones through multiple time leaps and her personality becoming more warped and cold from all the trauma.
- Older Alter Ego: After merging with Chronoa properly, Chloe will often age herself up to their adult self in order to fight at full power.
- Precursor Heroes: As part of the Timey-Wimey Ball she's stuck in, Chloe is part of a chain of heroes that goes Chloe —> Shizue —> Rimuru —> Chloe, making her a precursor to herself.
- Ripple-Effect-Proof Memory: Played with. Chloe doesn't start remembering her past journeys until she merges with her future self in the current loop, and even then she can only recall the last loop with good accuracy while past loops filter in and out. Hinata speculates this is similar to how even a normal human can't perfectly recall every past memory.
- Sharing a Body: Chloe takes it up a notch as not only does she host the spirit of her future self, but at one point she ends up hosting Hinata's spirit inside her during a 2000 year time jump to the past.
- Stable Time Loop: Chloe is part of a convoluted time loop, according to Ramiris. She's the Hero who sealed Veldora, who Leon was seeking to summon, and who Shizu admired and got her mask from in the past; having become a Demigod after countless time loops.
- Teacher/Student Romance: Chloe develops a Precocious Crush on Rimuru, who laments that she should have waited until they were 18 or 20 to confess.Even after the whole events of her time travel and fusion with Hinata her love for Rimuru is strong to the point that in the epilogue she along with Milim, Shuna and Shion arguing who would be Rimuru's "official wife"
- Time Master: Chloe's true power, which originally manifests as the Unique Skill [Time Travel] (which is Exactly What It Says on the Tin in a limited form) before evolving with Raphael's aid into the Ultimate Skill [Space-Time King Yog Sothoth], which allows her to control, stop, and travel through time at will. When she fully fuses with her future self and masters the Skill, it evolves into [Space-Time God Yog Sothoth Hortz], which boosts this power to Physical God tier levels.
- Walking Spoiler: Chloe's role in the story is incredibly significant, to the point that discussing anything about her at length, especially her character relationships, can lead into heavy spoiler territory. To emphasize just how spoileriffic she is, in ISEKAI Memories when her adult self makes its first playable appearance, she not only goes under the name of "Masked Hero", she's treated as a completely separate character in interactions and Bond Levels from regular Chloe when most other alternate versions of playable characters share these with their originals.
- World's Best Warrior: Chloe will eventually/has become this as the greatest Chosen Hero known throughout the world, possessing raw power to match a True Dragon combined with the swordsmanship honed from training under some of the greatest masters known in the world.

Orc Disaster
Geld
Orc King/Orc Lord/Orc Disaster
Voiced by: Kenji Nomura (Japanese), Jim Foronda (English)
Formerly a nameless Orc King who wanted to save his people from famine, he was granted a name by the demon Gelmud under the orders of the Great Demon Lord Clayman. Obtaining the Unique skill Starved, he was meant to become a Demon Lord capable of conquering and ruling the Jura Forest as their pawn.
- Adaptive Ability: As he's being burned by Rimuru's Flare Circle, he develops the Heat Resistance skill to tank the rest of it.
- Alas, Poor Villain: His death is portrayed as such. Rimuru killing him was clearly a Mercy Kill, to which the Orc Lord thanked him for allowing him to rest in peace.
- Anti-Villain: His people were starving, and he joined forces with Gelmud in order to save them.
- The Assimilator: His Starved skill functions similarly to Rimuru's Predator skill in that they both provide the potential for infinite growth by devouring others and adding their powers and skills to their repertoire.
- Benevolent Boss: Even after succumbing to hunger, he still loves his people. And while eating one of your own men for a power boost and healing would normally be a
Moral Event Horizon, the orc in question willingly offered himself up and didn't struggle even as he was being devoured. - Blessed with Suck: His skill "Starved" grants a Cannibalism Superpower onto everyone in his army and makes it so that they all share in their strength and power, making them akin to a swarm of locusts blighting any place they march through. However, it also afflicts them with an insatiable Horror Hunger and turns them into nearly mindless drones, the Orc King slowly being corrupted as he becomes more and more like a Demon Lord.
- Cannibalism Superpower: Since he can't directly absorb things like Rimuru, the only way Geld can actually use his Starved skill to the fullest is by literally eating people to absorb their power. "Helping" is the fact it also gives him Horror Hunger so that he's not too picky about the act of eating anything in front of him.
- Dragon Ascendant: Technically, he's already the Dragon-in-Chief for Gelmud and by extension Clayman, but upon deciding to take Gelmud's order to evolve to the Orc Disaster to heart, he chops Gelmud's head off and eats the corpse to do it, becoming the main antagonistic force for the arc.
- Dying as Yourself: His spirit passes on not in the form of the Orc Disaster, but the Orc King he once was.
- Evil Counterpart: Effectively one to Rimuru early on. Both have impressively large suites of powers based derived from devouring things and assimilating their abilities, as well as potent regeneration and adaptation. Especially notable at the end of the fight, first when he steals Rimuru's "It appears fire has no effect on me" line, then the fight culminates in a head-on clash between Rimuru's Predator and Geld's Starved skills as the two attempt to eat eachother first.
- Evil Is Bigger: He is nearly three times the size of a regular orc and about twice as big as his Orc Generals.
- Expy: Of Ganon from The Legend of Zelda. Both of them are giant pig-men who became a warlord and demon king after they were driven to desperation watching their people suffer in a desert waste. Geld's name in Japanese is even "Gerudo", the name of Ganondorf's people.
- The Good King: To the orcs. He was willing to abuse his Healing Factor and tear off his own limbs in spite of the pain to provide them some sort of food. In the Drama CDs, Veldora even praised him for his noble nature, admitting that it was why he didn't press Geld's spirit to stay with him and Ifrit.
- Healing Factor: Not only does he possess regeneration and healing magic, he can also devour others to quickly restore his stamina. It's so potent Hakurou slicing his head off just slows him down and Rimuru is forced to use Predator on him to win (and even then, he resists it longer than any other creature before him). Even when he was still nameless, he didn't think anything of tearing off his own limbs and letting his starving people eat them since they would just come back.
- I've Come Too Far: He tells this to Rimuru. After eating his benefactor, his own brethren and even several others, he feels that he cannot afford to lose.
- Large and in Charge: By far the largest of all the Orcs, even before his ascension to the Orc Disaster.
- No Place for Me There: In the Drama CDs, Veldora recounts how he offered Geld's spirit a chance to stay with him and Ifrit as a companion within Rimuru's Stomach, but Geld politely refused. For him, the knowledge that Rimuru would shoulder the burden of the orcs was enough, and Veldora didn't press the subject as he let him go.
- Power Copying: After devouring Gelmud, he gains the ability to use Death March Dance.
- Rank Scales with Asskicking: The leader of the Orcs and the strongest. While his soldiers were easily dispatched by Rimuru's subordinates, he was too strong for them, and Rimuru was forced to step up in order to deal with him.
- Stripped to the Bone: Predator strips him of all his flesh and leaves him a skeleton. He's still clinging to life even then and only gives up in full with Rimuru's promise.
- Super-Strength: He can match Shion's strength with ease.
- Take Up My Sword: Rimuru promising to do this for the Orcs in his place is what allows him to pass on in peace. Just as significant (not that either of them realized the importance of this at the time) is that Rimuru ends up inheriting Geld's Demon Lord Seed from devouring him, which would allow him to achieve his own Awakening to become a Demon Lord.
- Tragic Monster: His underlying tragedy is that he's The Good King driven to monstrous depths by evil benefactors, and he knows he's being manipulated but won't be able to save his starving people otherwise.
- Transformation Is a Free Action: Twice Geld devours people prior to fighting Rimuru that increases his power while Rimuru and his friends just stand there letting him do it. Had Rimuru simply attacked Geld after Geld killed Gelmund but before he ate Gelmund Rimuru would have defeated him easily.
- Unwitting Pawn: Subverted. He admits to Rimuru as he's being absorbed that he knew Gelmund was all but certainly using from the start, but he viewed the situation as a Deal with the Devil issue since to refuse would likely condemn his people to starvation.
- Wake-Up Call Boss: The first opponent Rimuru fights who legitimately provides a challenge (Ifrit was only an issue due to Rimuru not remembering he had Heat Resistance and the risk of weaker bystanders), due to possessing powerful attacks that require dodging or intentional nullification instead of simply straight-up No Selling and possessing a ludicrous Healing Factor.
- Well-Intentioned Extremist: All he wanted was to save his people from a famine, no matter the cost. Rimuru promising to save them is what allows him to accept his death with grace.
- The Worf Effect: Despite taking a good amount of damage from their assault, he proves to be too strong for the oni and Ranga to best, showing the gap between them and a Orc Disaster. He then gets this at the hands of Rimuru, whose Predator Skill is superior to his Starved one.
- Worf Had the Flu: While he did in fact evolve thanks to all the monsters he ate including Gelmund, Geld still didn't complete his evolution because he didn't devour any human souls to finish his awakening into a True Demon Lord.

An ancient monster of immense power comparable to a Demon Lord, known as the Ruler of the Skies. Sealed away by an ancient hero, it is unleashed with the intent of bringing calamity to Tempest.
- Animalistic Abomination: It is a one-eyed vaguely shark-like monster — with ray-like wings in the anime, defies gravity, possesses enough power to wipe out a country, and was born from a cloud of Veldora's magicules — technically making it Rimuru's sibling.
- Came Back Wrong: The Charybdis born from Yamza being forced to swallow its core fragment is explicitly noted to be weaker than the original, to the point even with it assimilating every source of magicules nearby it could grab (including several fallen majin and the Ice Blade), it would have self-destructed on its own within a day. Of course, it being born on the chaos of the battlefield makes destroying it a top priority regardless for the collateral damage.
- Curb Stomp Cushion: It withstands everything Rimuru's army throws at it and even fights Rimuru himself to a stalemate, but is effortlessly defeated by Milim who considered the fact she didn't kill Phobio in the process to be a sign of her restraint.
- Degraded Boss: Clayman's subordinate Yamza is forced to consume a fragment of its core after he's beaten by Albis and about to surrender, due to a post-hypnotic suggestion from his boss. It's weaker than the original, but still powerful, and it inherits Yamza's Doppelganger skill, which means that it can clone itself, and the Ice Blade's power. Benimaru takes it down singlehandedly thanks to having Took a Level in Badass due to Rimuru's Harvest Festival.
- Demonic Possession: As a spiritual entity, it needs a host in order to manifest. Phobio is tricked into becoming its host by Tear and Footman.
- Dragon Ancestry: Indirectly, as it is an Animalistic Abomination spawned from Veldora's magical energy, and vaguely resembles a draconic shark.
- Enemy Summoner: When summoned, it manifests a school of Megalodons — flying shark-monsters — using dragon corpses.
- Flechette Storm: It can fire its denticles/scales as razor-sharp homing projectiles.
- Gravity Master: It can manipulate gravity to enable itself and its Megalodons to fly. Rimuru gains this same ability after consuming its damaged core after removing it from Phobio's body.
- Healing Factor: It possesses Ultra-Speed Regeneration, the highest level of self-healing, which allows it to shrug off and heal away any damage that doesn't utterly destroy it in one shot. Unfortunately for it, Milim possesses such capacity to incinerate it so badly it can't heal away the damage. So did Benimaru thanks to getting a badass upgrade following Rimuru's evolution, using his Black Flames to make short work of it (admittedly a weaker version) seconds after it was forcibly reborn.
- No-Sell: Its special ability, Magic Jamming, makes it immune to magical attacks. Unfortunately for it, Milim's Drago-Buster isn't magic.
- Roaring Rampage of Revenge: Owing to its host being Phobio, it attacks Tempest looking to kill Milim.
- Sealed Evil in a Can: It was sealed away by a hero in the distant past, though Tear and Footman trick Phobio into unsealing it and becoming its vessel by saying it will give him the power to kill Milim.
- Unskilled, but Strong: Powerful enough to qualify as a Demon Lord-level threat strength-wise, but as it lacks any cunning or sapience to fully leverage its power it's not considered a proper S-Class monster like a Demon Lord would normally be.
- Worf Had the Flu: The Charbydis created from Yamza being forced to eat a core fragment is explicitly noted to be weaker than the original Charybdis, even if it possesses powers the original doesn't, and would have self-destructed on its own within a day. As such, Benimaru destroying it with one Hell's Flare, while impressive, still puts him well beneath the likes of Milim.
Veldanava
Stellar Dragon King
The most powerful True Dragon and strongest being in all of the multiverse. Currently dead, but his legacy has left a profound impact across the world millenia after the fact, and there are those who would seek to use that power for their own ends.
- Dragons Are Divine: While his other True Dragon siblings can be considered gods, Veldanava was God with a capital G.
- God Is Dead: Veldanava is the only True Dragon truly dead by the start of the story, and it's a driving mystery on why he hasn't resurrected. His death has been responsible both directly and indirectly for many major events since, and it's the main goal of Michael and the angels to bring him back, no matter the cost.
- God Is Good: In spite of his power, everyone who has something to say about Veldanava remembers him as a noble and generous soul who always tried to see the best in others and offered redemption and mercy to his foes, albeit also something of a prankster.
- Happily Married: To the human Lucia, with whom he had his daughter Milim. He would happily gush about her to his siblings, and it was through these descriptions that Veldora would actually come to understand standards of human beauty.
- The Maker: It was Veldanava who created the multiverse, the various dimensions, and the main world the story takes place on. He also established the Voice of the World, along with the evolution and Skill systems.
- Monster Progenitor: When Veldanava abandoned his old dragon body to take a human form after his existence became unstable due to the massive power loss from siring Milim, its decaying form spawned the mortal Dragon race.
- The Power of Creation: Creation Lord Ahura Mazda allowed Veldanava to create anything of his choosing as long as he had the sufficient knowledge and power to do so. This made Information King Akashic Records a very useful Required Secondary Powers. Notably, this seemingly was never inherited by another being after his death unlike how Michael went to Rudra and Uriel to Rimuru, until it's revealed Yuuki's Unique Skill Creator is in fact a degraded version of it.
- Star Power: He was called the Stellar/Star King for a reason. One of the powers he used to create the multiverse from nothingness was "Stardust".
- Superpower Lottery: Oh, where to begin. First of all, he's a True Dragon, a creature akin to a force of nature or god able to destroy the world at bare minimum. He also had no less than three Ultimate Skills: Justice King Michael, Covenant King Uriel, and Creation Lord Ahura Mazda. And then there's Information King Akashic Records, which gave Veldanava knowledge of everything in existence and supplemented his ability to create anything.
- Turn the Other Cheek: Veldanava's capacity for mercy and redemption cannot be understated even for those who were a possible great threat to the world. He was the one who offered Guy Crimson the role of Arbitrator because he saw Guy's innate interest in mortals, chose not to kill Ivarage and instead isolated him safely because he believed it was a shame to just murder someone who had no concept of right and wrong without giving them a chance to develop, spared Zelanus because he saw his sentience (the first Cryptid of Ivarage to possess it) as a sign he could learn and become his own person, granted Dagruel and Glassord mercy after splitting them from Ashura when they chose to atone for their actions, only punishing the unrepentant brother Fenn and even then just imprisoning him and letting his brothers watch over him, all to just name a few.
- World's Strongest Man: The most powerful being in the world hands down, possessing some of the most broken Skills alongside incredible and unmatched magical and physical might in the entire series. His sibling True Dragons together could barely compare to him, and he handed Guy Crimson the greatest Curb-Stomp Battle of his life to the point the prideful Primordial would only acknowledge him as his superior. And this was after he willingly gave up being both The Omnipotent and The Omniscient. It's telling he only died after he was Brought Down to Normal due to willing sacrificing much of his power over millennia through various acts.
Movie Exclusive Characters
Hiiro
A Kijin born in the same village as Benimaru and co. To help support his village, he decided to venture out as a mercenary alongside a small group of fellow ogres. Eventually, they were hired by Clayman as apart of his army for a period of time. When they heard news of an Orc Army from Orbic invading the Jura Forest, they deserted from Clayman's army against the terms of his contract. As deserters they were tracked down by Clayman's forces and systematically slaughtered. Hiiro and his men were retrieved by the nearby kingdom of Raja, where Queen Towa granted him a name to save his life. With his village destroyed, Hiiro decided to dedicate himself to repaying the debt he owed to Towa.
- BFS: He carries a Nagamaki that is as long as his body.
- Childhood Friends: He grew up in the same village as the Kijin of Tempest, and Benimaru, Shuna and Shion consider him their older brother figure.

- Elemental Hair Colors: He has crimson hair and can cast flames in his attacks.

- Red Eyes, Take Warning: His eyes turn fiery red when he's in an anger fuelled state.
- Roaring Rampage of Revenge: When he sees Geld in Tempest, he immediately attacks him to avenge the destruction of the ogre village. Geld almost lets himself get killed out of guilt, but Benimaru arrives just in time to save him. After talking things out, Hiiro realizes Geld isn't an enemy and makes peace with the orcs of Tempest.
- Samurai Ponytail: Like other Kijin, he wears Japanese-style clothing, with his ponytail adding to the samurai look.
- Survivor Guilt: He feels guilt over not being able to save his fellow ogres of his village and surviving while his comrades died from their wounds.
- Undying Loyalty: He pledges loyalty to Towa after she saves him, to the point that he would readily give up his life to save her.
Towa
- Voiced by: Riko Fukumoto (Japanese), Cherami Leigh (English) Foreign VAs
The Queen of Raja. She saved Hiiro's life by giving him a name and he has served her ever since.
- Anime Hair: She has brown hair with green twintails tied up at the front.
- Disappears into Light: Her body disintegrates into light after she overuses the tiara to save Hiiro. Luckily, Violet restores her back to normal.
- Disney Death: At the end of the movie, Towa uses all of the cursed tiara's power to resurrect Hiiro, but Violet undoes her sacrifice and resurrects her.
- Heroic Sacrifice: She uses all the power of her tiara to bring Hiiro back to life, costing her her life. Although, the sacrifice is immediately undone by Violet deciding to let her live anyway.
- The High Queen: She's a benevolent queen who is willing to give up her life for her subjects.
- Implied Love Interest: Hiiro is completely devoted to her and they have a very close relationship, but it isn't confirmed whether their relationship is romantic or a platonic master-servant one.
- Lady and Knight: The Lady to Hiiro's Knight. She's the queen who saved his life and he has sworn loyalty to her in gratitude.
- Magical Accessory: Her tiara is a cursed magical item that has been passed down in the royal family from generation to generation. It grants her the power to putify her kingdom's lake and even resurrect someone who has just died.
- Modest Royalty: Even though she's a queen, she wears a simple but elegant white tube-style dress accented with an orange skirt that's attached by her belt.
- My Greatest Failure: She feels guilty for not having enough power to save all of Hiiro's comrades along with him.
- Power at a Price: She uses the magical power of her tiara to neutralize the poison in the lake of her country and protect the people of Raja. However, the price to pay for this is a curse that eats away at her life.
- Secretly Selfish: She admits to Rimuru that she didn't save Hiiro completely out of goodness of her heart, but because she wanted him to be indebted to her and loyally serve her, as she wished for a noble and trustworthy vassal.
- Sugar-and-Ice Personality: She's calm, solemn and reserved, but it's clear she cares deeply about Hiiro.
- Tough Leader Façade: She puts on a strong front for her subjects, but she's actually very fragile because of the curse weakening her body and laments not being someone powerful enough to save as many people as Rimuru does.
Mobuji
- Voiced by: Mitsuru Ogata (Japanese), Mark Stoddard (English) Foreign VAs
The Prime Minister of Raja.
- Eyes Always Shut: He never opens his eyes.
- Face of a Thug: Despite looking like the sort of character you'd expect to be an Evil Chancellor, he's actually a benevolent figure, gratefully accepting Rimiru's aid in helping Towa recover her health.
Chikuan
- Voiced by: Shinpachi Tsuji (Japanese), Greg Dulcie (English) Foreign VAs
An Elven physician in the service of Towa.
- Evil All Along: He's revealed to be a demon like Lacua and he wasn't treating Towa's illness as he wanted her to be killed by the cursed tiara.
- Old Retainer: Being of a long-lived race, they have served the Queen of Raja for several generations.
- Pointy Ears: He has long and pointy elf-like ears.
- Pragmatic Villainy: While he doesn't do anything to help Towa's condition, he also doesn't do anything to stop Rimuru from helping, implying that he understands Violet's disposition much better than Lacua.
Raja Minister
- Voiced by: Ken Uo (Japanese), Sean Hennigan (English) Foreign VAs
A Minister of Raja. Together with Mobuji, he coordinates the administration of Raja.
- Everyone Calls Him "Barkeep": He's only known as the minister and his actual name isn't mentioned.
- Face of a Thug: Much like Mobuji he looks like a stereotypical evil character, but the two of them are actually quite benevolent and willingly accept help from Tempest in both saving their queen and stabilizing their kingdom.
- High-Class Glass: He's a minister wearing a monocle over his left eye.
Lacua
A Daemon and the main antagonist of the movie Scarlet Bond. He took the guise of a peddler who frequented Raja and dealt in rare and precious gems while he secretly ensured the continued use of the Tiara by Towa from behind the scenes.
- All for Nothing: His attempts to accelerate the curse for Violet's sake only loses her favor and his life. And to rub salt in the wound, Violet then revives Towa after she falls to the curse and breaks off the contract.
- Devil in Plain Sight: He couldn't look more evil and shady if he tried, yet no one in Raja suspects him and Hiiro trusts him completely.
- Didn't Think This Through: It never occurs to him that Violet would be a Fair-Play Villain who is playing a game and is patient enough to wait for her chance to manifest a new body (she even notes to Diablo that she expects one of Towa's descendants, rather than Towa herself, to be the one who finally falls to the curse). When Violet finds out that he stacked the deck in her favor, she is livid and cuts all ties with him, leaving him at Rimuru's (non-existent) mercy.
- Evil Is Hammy: He loves indulging in Evil Laughs and over-the-top Evil Gloating speeches.
- Fangs Are Evil: He's an evil Daemon with a mouth full of fangs.
- The Heavy: He's a minion of Violet, the one who cursed the Raja royal family long ago. Since Rimuru quickly fixes the curse that poisoned the kingdom's lake and gives Towa the medicine to improve her health, Lacua decides to take matters into his own hands and tricks Hiiro into taking a Cursed Orb to force Towa to overuse the cursed tiara.
- Manipulative Bastard: He lies to Hiiro by telling him about a ritual that'll supposedly save Towa's life in exchange of his own, but he actually makes him swallow a Cursed Orb that turns him into a monster and forces Towa to use the cursed tiara's power to save him.
- Overzealous Underling: Violet gave the cursed tiara to the Raja royal family and placed a cursed circle in the lake to poison it, which would force the queens to repeatedly use the tiara and sooner or later give into the curse that would allow Violet to take over the body of someone of the bloodline. Violet only asked Lacua to observe the situation in Raja, but when he realizes that Rimuru fixed everything, he can't stand that Violet will lose the gamble and takes it upon himself to force Towa to use the tiara again by cursing Hiiro, hoping that he will earn Violet's praise and favour by ensuring she wins her "game". To his shock, Violet is not happy with what he did and leaves him to his fate when Rimuru comes to kill him.
- Pointy Ears: His ears are long and pointed.
ISEKAI Memories
Shinsha
Voiced by: Tomori Kusunoki
A mysterious intelligent slime who claims to be Rimuru's daughter.
- Alternate Self: Technically, she's actually this as a mirror self...but specifically Shuna's ideal of a "cuter Great Rimuru".
- Berserk Button: She won't tolerate anyone doubting she's Rimuru's daughter.
- Big Damn Heroes: Her first appearance to Rimuru and company comes when she swoops in and absorbs Dodomeki via [Predator].
- Cannibalism Superpower: As she has [Predator], she gains the powers and abilities of those she absorbs/consumes. After she consumed Dodomeki, Izis then had her devour Vajra, Guitar Wolf, and Jinfrit to grow stronger, and later still she eats Trishula, Scylla, and the Orc Thirst's head.
- Hair Antennae: She has two of these in her human form, very similar to the two slime strands that poke up in her slime form. It's actually a hint that she's Shuna's delusion of a "cuter" Rimuru.
- I Just Want to Be Loved: After fighting her for a bit after she evolves and hearing of how alone she felt due to living in the mirror world with Izis not giving her the attention she desired as her "child", Rimuru deduces that this the main source of her troubles and helps to ease her loneliness by giving her a hug. This not only works, it dissipates her Black Hole skill that was threatening to swallow him up and destroy her.
- Lamarck Was Right: She claims to be Rimuru's daughter, and she does possess many of Rimuru's Skills, most notably [Predator] and [Great Sage]. She technically is Rimuru, or rather a version of him now a her imagined up by Shuna.
- Master Swordsman: Subverted when she's given a sword to have a fight with Gazel, and justified by the fact it's the first time she's ever held a sword. As noted by Gazel, her "style" could be best described as random: she doesn't use any move recognizable by a school of swordsmanship, and none of her strikes resemble existing techniques. It would be more accurate to call her swordsmanship just swinging a long steel weapon at her opponent with no regard for even which way the blade is facing. The only things going for her are the sheer speed, strength, and determination behind her moves, all of which by that point are comparable to an Awakened Demon Lord. Later, she manages to trick a skilled Dwarven swordsman that she's mastered Gazel's swordsmanship from observing his movements during that spar, but after the fight it's made clear all she actually did was imitate Gazel's defense (specifically his parrying) and simply tricked him into thinking she had.
- Non-Mammalian Mammaries: Played with, in that her human form noticeably has breasts rather than lacking any such characteristics like Rimuru's.
- Pink Is Feminine: Her slime form is colored pink and later on her silver-blue hair turns pink and she identifies explicitly as female. It's a hint to Shuna's hand in creating her.
- Power Dyes Your Hair: Her silver-blue hair turns pink after absorbing both Scylla and the Orc Thirst's severed head and acquiring [Gluttony] from the latter, with her stats all rising to match Rimuru's own.
- Red Eyes, Take Warning: She has bright red eyes similar to Raphael when the latter is controlling Rimuru's human form. Or rather, very much like Shuna.
- Strong Family Resemblance: She claims to be Rimuru's daughter and her human forms looks like a female Rimuru.
- Vibroweapon: Her Signature Move is "Handshake of Purgatory", where she manipulates a bunch of Steel Threads into a massive hand and vibrates the mass so fast that it can cut through Multilayer Barrier and Body Armor, while it's also set on fire to dispel any shadows and channeling Black Lightning to produce an electromagnetic field.
Izis
Voiced by: Rie Takahashi
The mysterious "Witch of the Mirror" who has an interest in Rimuru Tempest.
- Achievements in Ignorance:
- When she blasts an exhausted Rimuru and Shinsha in a rage, she wasn't expecting to end up not only jettisoning both of them back into the real world (albeit separated), but also absorbing Shinsha's left-over remains, gaining incredible power and upgrading her Unique Skill.
- She manages to make herself an Awakened Demon Lord in the process of trying to do the same to Shinsha, having not expected for the gathered souls to go to her and activate her Awakening first. She can only chalk it up to having more souls on hand due to the years she's spent casually snacking on victim's souls giving her that leg-up.
- Blessed with Suck: How she views her Ultimate Skill [Amalthea]. Cool, the particle construction limit within the Mirror World is now lifted, so she can now create a universe comparable to the real deal in size if she wants to and do whatever she wants. But as she laments, she's still just playing make-believe by herself for eternity, just with "a bigger room" and all the "toys" she could want. It's still not real.
- Despair Event Horizon: She doesn't cause these, but rather exploits them. Every time she's created an Alternate Self of an existing character, she's always come to them in a moment of incredible vulnerability, most notably with Ifrit and Shion.
- Ignored Epiphany: Despite having just saved Shinsha from being possibly killed by Noir, Izis tells herself she didn't do it out of any goodness but simply to keep a possibly-useful pawn on hand. This despite the fact that hearing Shinsha comment about not wanting Izis to be lonely not long before was part of what prompted her actions in the first place.
- I Just Want to Be Free: Her major goal is to escape the mirror world in which she's been trapped for centuries. She had actually spent time studying Veldora's seal by the [Unlimited Imprisonment] for inspiration before Rimuru came along and ate it, which now motivates her attempt to capture Rimuru to use him to escape. Even after awakening as a Demon Lord and gaining an Ultimate Skill that lets her become a Reality Warper of the mirror world, she can only quietly despair that this still didn't give her the freedom she so craves.
- Impossibly-Low Neckline: Her dress barely hangs off her shoulders, showing a lot of cleavage.
- Kryptonite Factor: Those with the "Veldora Factor" (magicules originating from Veldora) are capable of defying her control. This is how Shinsha (who has a fascimile of Veldora within her) and Blue Sky Fang Phobio (possessing Charybdis' essence) are able act independent of her will, with the latter only losing control when Izis outright attacks him and weakens him enough for Charybdis itself to assert itself.
- Laser-Guided Amnesia: Those who enter and exit her Mirror World will forget everything that happens within it and will only remember everything once they come back. Rimuru compares it to accessing "saved data".
- Logical Weakness: As her power is heavily dependent on mirrors, even the quality of the mirror she uses to send people to her realm is important, as the less reflective it is the less power she and her subordinates can bring out. Not to mention she needs a mirror to interact with the real world at all, so at times she can't exactly be picky about what she uses. Also, while she can bring a person's "dreams" to life, she's limited to what exactly her victim's dream is. When she first tried to use it on Rimuru, his two "dreams" were to have a functioning town with plumbing and to see his original human self. The second in particular just created a powerless Muggle that would stand no chance of beating him even as he was when he first established the Goblin Village.
- Magic Mirror: Her Unique Skill [Mirror of Delusion] allows her to look at the subconscious minds of others through reflective surfaces, including mirrors and puddles. She can then materialize that version of the person into the mirror world. She can also pull people into the mirror world through reflective surfaces, but the strength of herself and the mirror copies she creates are affected by how "mirror-like" the surface she uses to pull people in is.
- Mirror Self: She can create these via her Unique Skill, usually by appealing to a being in a Moment of Weakness and then creating an "ideal" self within the mirror world who serves her. The originals are never aware outside of the mirror world of this thanks to Laser-Guided Amnesia.
- The Power of Creation: She can materialize other's dreams, be they their ideal selves or even entire landscapes through her Unique Skill [Mirror Of Delusion]. However, she herself laments that ultimately it's all temporary. Once she powers up and evolves it to [Mirror of Revision], she gains the power to create monsters from her imagination. Finally, her Ultimate Skill [Amalthea] allows her to create a universe comparable to real space within her Mirror World.
- Sexy Slit Dress: Her dress has a long slit cut out for her left leg.
- Villain Takes an Interest: She's been intrigued by Rimuru since his days in the Sealed Cave after he devoured Veldora, seeing him as her ticket to freedom from the mirror world, and the bulk of the original story of the game is motivated by her trying to get her hands on him in her desire to escape the mirror world. This is much harder than it sounds given Rimuru's canonical constant Took a Level in Badass moments, something she actually bemoans more than once.
- You Have Outlived Your Usefulness: She willingly feeds Vajra, Guitar Wolf, and Jinfrit to Shinsha to accelerate her development, citing that since none of them were strong enough to defeat Rimuru themselves, they can at least empower Shinsha to do it herself.
Mirror Selves
Existences created by Izis' Unique Skill [Mirror of Delusion] to serve as her forces.
- Despair Event Horizon: Several of them, such as Shion/Dodomeki and Gabiru/Trishula, were created when Izis appealed to them in moments of extreme emotional vulnerability (Shion reeling from the slaughter of the Ogres, Gabiru realizing how out-matched he was by the Orc General) that made them very eager to accept her bargain for strength.
- Fighting for a Homeland: Though loyal to Izis, as he's made from the regrets of the Kijin Kokuyo wants to build a new Kijin village where he'll stamp out their weakness.
- Graceful Loser: Despite proving Noir's inferior, Kokuyo doesn't hold any ill will to his foe before his death, even dismissing Noir's musing that he could try to escape by pointing out Noir would never allow himself to bungle so bad to let a foe escape.
- Revenge Before Reason: Dodomeki makes it clear she wants to kill all the Orcs for what they did to the Ogre Village, and she won't settle for anyone but her dealing that vengeance out. As such, she's all for killing Rimuru for being an obstacle for that, and chastises Shion for seemingly letting someone else do what should be their job.
- Took a Level in Badass: All of them have some form of power-up compared to their original selves:
- Vajra: A Gobta who possesses the [Black Lightning] Skill.
- Guitar Wolf: A Ranga who assimilated the Stick Steel Threads and can now manipulated them to produce powerful sonic attacks.
- Jinfrit: An Ifrit who possesses Shizue's [Degenerate] Unique Skill and has expanded his Elemental Powers to include ice by removing heat from his surroundings and wind by using [Degenerate] to combine fire and ice together. He goes from being No Selled by Rimuru to actually being able to hurt him.
- Dodomeki: An Ogre Shion who in addition to increased physical abilities (if not quite as strong as Kijin Shion herself) hosts the souls of all the slain Ogres of her village and can use their souls to heal any damage, along with a powerful Beam Spam attack.
- Trishula: A Gabiru who fused with his Vortex Spear to increase his piercing power to incredible heights such that he can easily kill the same Orc Generals that overpowered his old self.
- Orc Thirst: An Orc Disaster that successfully ate Gabiru as Gelmud wanted, increasing his overall power as well as wielding the Vortex Spear himself to absorb and control water.
- Phobio, the Sky Blue Fang: A Phobio that managed to absorb and master Charbydis' power, becoming the Demon Lord that Tear and Footman tempted him into being, and thus is able to use Charbydis' abilities such as Magic Jamming and Tempest Scales.
- Scylla: A Charbydis that managed to overwhelm Sky Blue Fang Phobio's control due to Izis' interference, achieving greater power and possessing heightened intelligence.
- Kaleidoscope Sky: A Sky Dragon created as a test of Izis' newly evolved [Mirror of Revision] Unique Skill. Designed to be explicitly superior to the likes of Scylla or Sky Blue Fang Phobio, it possesses incredible magical power and defenses (including repelling physical, magical and attribute-based attacks individually), but its first act upon creation was to ignore orders to track down Rimuru and go after Shinsha due to Izis' evolved Skill being caused from absorbing some of Shinsha's body. It takes the aid of the Ingracia child Otherworlders for Shinsha to beat it.
- Kokuyo: A Benimaru that Izis tempted by pointing out how much he's started depending on Rimuru like a crutch during the attack on Tempest by the Falmuth Otherworlders and forward-guard, manifesting the regrets of the surviving Kijin of the massacre into a dark copy of him with all their powers (save Shion's since she's currently dead), such as Benimaru's flames, Kurobe's smithing skills, and Hakurou's Third Eye. He's strong enough that Shinsha is no match, though he's not experienced enough to pose much of a threat to Noir.
- Hyuga: A majin version of Hinata Izis created with the intent of being able to take on Rimuru now evolved into a True Demon Lord and his subordinates. While she has all of Hinata's abilities at the time she first fought against Rimuru, her true danger is her possession of her own version of Deadend Rainbow complete with its "death in seven strikes". She nearly kills Benimaru and Souei and is only fatally injured due to the interference of Gobta letting all three of them gang up on her at once in her moment of confusion plus Taking the Bullet for Izis.
- Veldora Against: The copy of Veldora that was created when Shinsha was as a copy of Rimuru, sealed within the Unlimited Imprisonment within her. While he spent most of the story sealed away, Izis finally lets him out by using her Ultimate Skill [Amalthea] to forcibly destroy the Unlimited Imprisonment and letting him manifest through Shinsha as her last hope of leaving the Mirror World. He appears as a Red and Black and Evil All Over form of Veldora.
- Worthy Opponent:
- Trishula recognizes Rimuru as such, stating that he now sees that the slime is truly strong enough to defeat the Orc Disaster himself. And of course, he wants to prove himself in a one-on-one against Rimuru.
- Phobio has a similar mindset, outright declaring that he's not being controlled by Izis and that he simply wants to prove himself superior to Rimuru and so stand on the level of Carrion. So much so that he defies Izis herself, outright stating he's fine with dying if it happens despite him giving his all.
