Chester Ray Galford
The Feudal Lord of Faltra City. He is a Lieutenant General who was previously a Hero.
- Absurdly Sharp Blade: His sword can cut through Alicia's blade before she even finishes pulling it out of her sheath.
- Armor-Piercing Attack: Somehow, he's able to bypass Diablo's physical damage reduction gear.
- Brutal Honesty: The man does not mince words, period. He will tell you exactly what he thinks of you, good, bad, or ugly.
- Combat Pragmatist: He waits until Diablo and the elves of the Greenwood Kingdom have exhausted each other to bring his troops in. It almost worked, and it would have if he had simply waited a bit longer until Diablo and his companions had left the scene, instead of going after Shera for his own agenda.
- Death of a Thousand Cuts: His primary strategy of going up against Diablo was this. He used many quick, small damage attacks to keep Diablo off-balance and pile up the damage. Unfortunately for him, Diablo is a top-tier PvP player and has plenty of experience dealing with such tactics.
- Double Think: Diablo wonders if Galford really wanted him to prevent the war with the Greenwood kingdom because Galford filed an official request with the adventurer's guild stating that the elves were planning to launch war on Faltra in 10 days, but didn't notify the adventurer's guild that two days had already passed since the elves made the ultimatum.
- Entertainingly Wrong: As Sylvie tells him that Diablo is not a bad person, as a result of her first-hand interactions with him, Galford retorts with a list of accusations that do fit neatly with the information he has on hand, but just happen to be 180 degrees out of character for what truly happened, except for the "attacking the Town lord" bit, where Sylvie reminds him that Galford is the one who attacked Diablo, not the other way around.
- Famed In-Story: His exploits as a hero who single-handed fended off an army of demon beasts to protect the city of Faltra are well known.
- Foil: To Diablo. While both of them subscribe wholeheartedly to Good Is Not Nice, Diablo seeks to avoid conflict, and killing while Galford pre-emptively seeks it out.
- General Badass: A Lieutenant General, and uses abilities reserved for players of at least level 120.
- Good Is Not Nice: He's even more condescending, arrogant, and spiteful than Diablo. In addition, he's horribly racist, sexist, and petty, almost to the point of Hate Sink, but he is an officially recognized hero who had a major role in the defeat of Demon King of the Brain, Enkvalos 30 years ago, in-universe, and does put the well being of the citizens of Faltra first.
- Heroes Prefer Swords: He wields a longsword in battle.
- Jerkass: The man is a near complete dick, to say the least, with his sole redeeming point being his earnest desire to protect his territory.
- Jerkass Has a Point: In volume 4, the audience learns that Diablo's experience with the adventurers in Faltra is the exception, not the rule. In general, adventurers are a selfish, greedy, cowardly lot that will screw each other over, given the chance, and cannot be trusted.
- Kill Me Now, or Forever Stay Your Hand: He dares Diablo to kill him after Diablo beats him in a duel to protect Shera. Diablo rightfully suspects a trap of some sort.
- Lightning Bruiser: Not only does he move so fast, even the level 150 Diablo can barely track him, but he hits hard enough to break metal.
- Magic Knight: He primarily attacks with his blade, but he is able to imbue it with various elements, trap Diablo in a magical barrier that he had some trouble escaping, and conceal an entire army with an invisibility cloak, implying that he also has capabilities in support magic.
- Man in White: Goes to show how wealthy he is since a white uniform easily gets dirty.
- Might Makes Right: By his own admission, the only thing that matters in his mind is who has the higher attack level. Unfortunately, he said this to Diablo.
- Never My Fault: His response when Sylvie reminds him that he's the one that attacked Diablo, not the other way around?"As I thought, I can't trust that guy at all."
- One-Man Army: A legendary warrior able to singlehandedly repel an army of demons, just like Diablo. He is also at the very least level 120, possibly higher as he was able to give Diablo serious trouble (admittedly after the latter had already fought off an army of elves and a super hydra). In a world where most people are fairly low level, the man stands out as being obscenely strong.
- Real Politik: Benefit, or Liability, that's all he cares about when recruiting "heroes" for his city.
- The Rich Have White Stuff: His uniform is white.
- Ungrateful Bastard: He constantly looks down on adventurers as a whole, especially Diablo. He's quick to insult and belittle them at any opportunity, despite the fact that the city only exists because the adventurer's guild took the demonic being attack head-on, while he was in his mansion doing nothing, and constantly go into danger to deal with threats that the local knights can't handle. This leads him to make two critical mistakes. First, he calls Diablo "cowardly," looking to make excuses for his incompetence when he sought out mission-critical important info from Galford, which allows Diablo to counter with the fact that Galford did nothing during the invasion, and Galford launches a sneak attack after Diablo's exhausted from fighting with the Force Hydra to seize Shera, by force, killing everyone in his way on the pretext that "lowly adventurers can't secure Shera" despite the fact that Shera was only in prince Kiira's custody because the elven prince had used the citizens of Faltra as hostages to make it happen.
- Well-Intentioned Extremist: He doesn't take chances in protecting the city of Faltra. In order to keep the citizens safe, he's more than willing to launch a war of extermination against the elves, even if they've already surrendered, and hold their princess, Shera, hostage. He only made one small mistake, by antagonizing Diablo in the process.
The proprietor and idol of the Relief Inn.
- Cat Girl: A Pantherian.
- Cat Smile: The manga illustrates this as her default expression.
- Death Glare: Hers can terrify both Rem and Shera, and is the only time her cat smile disappears.
- Genki Girl: Very happy and upbeat. Don't let that fool you.
- Intrepid Merchant: As long as she's facing a paying customer, she doesn't care about race or origin, whether Human, Pantheran, Demon or even Fallen, it does not matter to her. She further doesn't care what customers do in their rooms so long as they don't bother their neighbors, or cause property damage.
- Reasonable Authority Figure: After some bandits blow up the wall to the room shared by Shera, Rem, and Diablo, and the three apologize for the inconvenience, she doesn't threaten or kick them out, but merely presents them with a bill for repairs. When Diablo realizes it's a sum they can't possibly afford, he recommends Mei take it up with the guilty parties, ie, the criminals who blew the hole in the wall in the first place, and she goes on to do so.
- Say It with Hearts: The manga illustrates her lines almost always ending with a "star" icon.
- Skewed Priorities: When Diablo openly declares his intent to "torture" Rem, and Rem objects, rather than be concerned about the torture, she's concerned that Rem's being too loud.
- Blade on a Stick: Wields them as a guard.
- Face Death with Dignity: Knowing full well that a direct fight with the 100 Fallen army was suicidal, he still refused to abandon his post, fully prepared to die. Fortunately, Diablo stepped up and took on the attack instead.
- Knight in Shining Armor: He embodies everything one would expect of an ideal knight. His courage and dedication are what motivates Diablo to come to the defense of Fort Ulug during the 100 Fallen assault.
- Nerves of Steel: He was willing to face an advancing army of 100 Fallen, despite knowing he didn't stand a chance so that the farmers and other civilians could evacuate into the city. Fortunately, Diablo provided interference and drove off the Fallen.
- Absolute Cleavage: Her dress really works to show off the goods.
- Aura Vision: She can see the flow of magic power.
- Childhood Friends: With Celestine. According to her testimony, the two of them grew up together. While Celes has exceptional talent in everything else, Medios mastered Aura Vision three days earlier than her.
- Happiness in Slavery: When Diablo enters her tent, he notes that none of the slaves show signs of abuse, and are actually perfectly healthy, both in mind and body, to his perfectly understandable surprise.
- Hard Work Hardly Works: Double subverted. While her hard effort was sufficient to overcome Celestine on Aura Vision, by a mere three days, Celestine's raw talent overcame her in everything else regarding magic. This may explain why she prefers the slaver industry over being a magician.
- Impossibly-Low Neckline: The "V" of the dress reaches her waist.
- Impractically Fancy Clothes: If she does anything aside from a very slow and graceful walk, she's likely to fall out of her dress.
- Intrepid Merchant: A slave trader.
- Little Black Dress: At least in the manga. Her outfit wouldn't be out of place at a cocktail party or a fancy ball outside of a Victorian setting.
- Peek-a-Bangs: She's illustrated with hair that covers one side of her face in the manga
- Pragmatic Villainy: While "villainy" might be a bit much, seeing as slavery is perfectly legal, and accepted, in the world setting, she admits that she keeps slaves both physically and mentally healthy because it would hurt her profit margin if they were openly hurt or abused. In fact, she claims that she treats the slaves she sells as if they were her children in an orphanage, and strives to see them go to good homes. Though she sees sex-slavery as a perfectly valid "occupation."
- Rapunzel Hair: Her hair is illustrated reaching her waist.
The Human Guildmaster of the Faltra's Mage's Association.
- Adaptation Personality Change: In the anime, she is still a Nice Girl, but her "asshole threshold" for people like Galluk is considerably lower. She pointedly does not tolerate his racist non-sense and disciplines him both quickly and harshly when he acts out, not that it helps.
- Aura Vision: Can see the flow of magic power.
- Barrier Maiden: Maintains the barrier of Faltra City.
- In-Series Nickname: Celes
- Nice Girl: Perhaps a bit too nice. According to Rem, the reason Galak's ego got so big is that Celestine coddled him too much, and he came to believe he's incapable of wrongdoing. In fact, Rem seeing Celes frown is a sign that a line has been crossed.
- Rapunzel Hair: As seen in the page image, her hair easily reaches past her waist.
- Reasonable Authority Figure: When Rem informs her that Demon King Krebskrum has been reborn as a small child, rather than alert the kingdom, the church, and the world, she agrees to meet the little girl first, in person, and in as private as she can. It helps that Diablo is also present, and he's proven himself trustworthy by repelling a Demonic being attack numbering 100 or so, and saved the town from Gregor first, without asking for a reward.
- Shipper on Deck: She fully supports Rem + Diablo. Even more so after Diablo pulls a Big Damn Heroes and saves Rem, Emil, and herself from Gregor, then goes and deflects the praise.
- You Gotta Have Blue Hair: Her hair is noted to be sapphire blue.
- Asshole Victim: He was a self-righteous and racist jerk who never knew when to give up when he was made a fool of. It wouldn't be much of a stretch to say that readers don't miss him.
- Entitled to Have You: To Rem, because she's highly valued by Celestine, despite his demi-human racism, he insists on having Rem romantically involved with him, not anyone else because he believes himself superior to everyone, on every point, without exception.
- Fantastic Racism: Very racist against Demi-humans, and other non-humans.
- Foreshadowing: His go-to summon is a salamander, a giant, fire-breathing reptile. He later gets taken over and becomes the body of Gregor, a large, lizard-man Fallen.
- Hypocrite: To the point of Moral Myopia. "To protect the dignity of the Magician's guild," and support his own Fantastic Racism, he goes full-on Rules Lawyer, cracking down on the slightest infraction, real or imagined. In pursuit of his grudges, however, the rules clearly don't apply. When he is called out in it, repeatedly, he honestly and completely fails to comprehend how he can possibly be wrong.
- Ignorant Of His Own Ignorance: He may have the mightiest summon shown, a whopping lvl 30 Salamander, but he's nothing to anyone who's fought even one demonic beast.
- Insane Troll Logic: He thinks the best way to court Rem Galleu is to attack her travelling companions, and when that doesn't work, and he finds himself being dismissed from the Mage's Association due to his many crimes, that even the overly nice and forgiving Celestine can't ignore, he calls the Mage's Association and Celestine, "strange" for firing him and his "unparalleled genius," resisting to the point of violence, even "punishing" the mages that tried to take his cloak.
- Killed Off for Real: By turning into the body of Gregore.
- Never My Fault: All the rotten things he does? It's all Diablo's fault! Dammit! And the Demi-humans he manipulated to go after Diablo are useless because they fail.
- Not Good with Rejection: When Rem honestly tells him that the way he's pursuing her is creepy, at best, he's very quickly Driven to Madness.
- Selective Obliviousness: He's present when Celestine asks Diablo to set Rem free, and Diablo specifically says that he doesn't know how, and is not keen on forcing her to go with him against her will. Galak's response? Accuse Diablo of being rude for daring to outright and completely refuse Celestina's request.
- Small Name, Big Ego: He's so under-leveled and pathetic, he's an annoyance, at best. Yet he thinks he's the mightiest person in the world.
- Surrounded by Idiots: He comes to this mindset to rationalize why nobody agrees that he's in the right, and Diablo is in the wrong. Stabbing himself with the dagger that allows Gregore to possess and destroy his body, "because nobody can understand his genius."
- They Just Don't Get It: No matter how many times he's told, punished, or made well aware of how his actions are wrong, even after he's dismissed for using the name of The Magician's guild to commit outright fraud, for the purposes of staging an ambush, he still can't comprehend how he could possibly be wrong.
A Human who is the Adventurer's Guild's #1 《Superhuman Warrior》 and Warrior Instructor.
- Ascended Fanboy: Of Diablo. Despite an initial misunderstanding regarding the situation with Rem and Shera, he warms up to Diablo in a hurry when he learns Diablo is actually Rem and Shera's closest and most powerful ally.
- Big Damn Heroes: Appears just in the nick of time to rescue Rem and Celestine from Gregore. While he wasn't strong enough to deal with Gregore himself, he did buy some much, much needed time for Diablo to show up. He does it again when a group of rogue adventurers tries to kidnap Shera for the bounty posted by her brother.
- Bling of War: Wears gaudy golden armor.
- Bunny-Ears Lawyer: Despite his constant hammy behavior, and womanizing, he's a very competent and noble knight. Faltra is lucky to have him.
- Casanova Wannabe/Chivalrous Pervert/Handsome Lech: He's quite attractive and always jumping into danger, to the point of Leeroy Jenkins when a woman is involved.
- The Dulcinea Effect: Lampshaded. He will rescue a woman, no matter what.
- Good Is Not Soft: When he captured the kidnappers who tried to sprit Shera away for the bounty, he boldly proclaimed the intent to put them all through Training from Hell to beat their misogyny out of them.
- Heroes Prefer Swords: His weapon of choice is a sword, and he's surprisingly skilled with it.
- Knight in Shining Armor: Literally. His armor is radiant and is probably the best knight in the city of Faltra, if not the kingdom who isn't a feudal lord.
- Knight Templar: His introduction implies he's this, totally ignoring the women he's supposed to be rescuing in favor of fighting an innocent (if rude and aggressive) man. Averted by the end of the scene, when the misunderstanding is cleared up and he reveals himself to be a genuinely good person who can recognize when he's misjudged someone.
- Averted again when Klem goes berserk for the first time. Once he sees that the feared Demon Lord is really just a child with an odd family, he promises Diablo he'd never do anything to make her, or Shera and Rem, cry.
- Large Ham: He has a very loud and boisterous personality. His "womanizing" antics are purely for show, and he does it purely to get a large reaction, good or bad. When a lady responds to them stoically, in a calm and rational manner, he's visibly downtrodden.
- My Significance Sense Is Tingling: Subverted. He jokingly comments that he could "smell" Shera in trouble when he came to her rescue from kidnappers, but in truth had used his connections as the Warrior examiner for the Adventurer's guild to scout out Shera, when he heard of the bounty on her head, so he could be nearby if she needs help, which she did. It's also justified that looking out for the citizens of Faltra, of which Shera is a member, is also part of his job.
- Took a Level in Badass: His fight with Gregore and subsequent healing by Diablo's healing potion boosted his abilities so immensely, even Diablo did not recognize him on their next encounter until he took off his helmet and introduced himself, again.
The Grasswalker Guildmaster of Faltra's Adventurer's Guild.
- Crouching Moron, Hidden Badass: She can terrify Galford with a single Death Glare. Note that Galford is at least level 120.
- Does Not Like Shoes: Her Light Novel and Manga versions have no practical shoes, just wrappings which shows her toes, while her anime version wears shoes that can cover her toes.
- Green Thumb: She specializes in using plant-based spells.
- Immodest Orgasm: Not quite to the same degree of Rem or Shera, but the one time she ends up naked in the arms of a drunken Diablo, she has time for a few half-hearted protests before he reaches down, she gets loud, and the following page has her in a euphoric daze.
- Little Bit Beastly: Being a Grasswalker, she has rabbit ears and tail.
- Shameful Strip: Played for laughs and fanservice. After she feeds Diablo some alcohol rumored to restore MP, he immediately goes into a Fugue where he drags her into bed, strips off what few clothes she has, and gropes her to orgasm, before falling asleep and using her as a body pillow, where she can't escape his grip.
- Shameless Fanservice Girl: Even though she treats her outfit like a uniform, and it probably is, she still knows full well the effect it has on certain men, and doesn't hesitate to play it up for all it's worth when she has to.
- Shipper on Deck: She wants Diablo and Shera to get together, and even dressed up Shera in very stripperific clothes to make Diablo "energetic."
- Shoot the Dog: Her duty as the leader of the Adventurer's guild forces her to demand Krebskrum be put down after the rampage triggered by Saddler's acts. She doesn't like it, but the safety of the six races is her top priority. Fortunately, Diablo finds another way.
- Stripperific: Her outfit.
- Trap Master: Specializes in support magic that traps opponents.
- Vague Age: While she is an adult, her true age is never made clear, and even Diablo knows it's rude to ask without very good reason.
King Delouche Xandros
- Freaky Is Cool: Or Admiring the Abomination depending on which character you ask. When he had an audience with Diablo, he was ecstatic at meeting "The Demon King of Another World" and cheered when Diablo smacked down a rude noble who insisted that Diablo's strength was a lie and came at Diablo with a sword by cowing the guy with an Element Chemical Magic spell that blew up four castle walls, giving the throne room a brand new flow-through ventilation system.
- Gilded Cage: How he treats "guests" he actively summons to the capital. He puts them in a fancy suite, their needs all attended to by servants, but they can't leave... for months. He wisely makes an exception for Diablo whom he asks to come to the throne room immediately.
- Manchild: He has a very immature temperament and seeing Diablo in action had him giggling like a small child. Fortunately, he has good and trusted ministers that help rein in his more destructive tendencies, and he's otherwise a good and decent individual.
- Orcus on His Throne: He has yet to have an appearance outside the throne room. Justified in that he's noted to be of ill-health and can't leave the castle, even if he wants to.
- Real Politik: Downplayed but present. He strives for the best interests of the human kingdom, regardless of the means, but strives to keep everything honorable and above-board whenever possible.
VinashinThe Royal Seer.
A Human Imperial Knight. She is the daughter of a duke house.
- Abusive Parents: Her mother and father are real pieces of work. While they may give lip service to caring about her well being, in practice, they actually couldn't care less. They force her to study "proper" education until it damages her eyesight, then berate her for the glasses she wears so she can actually see (at least well enough to actually be able to recognize who she's talking to), routinely go through her possessions without notice or consent, despite her being a full-grown adult, and summarily destroy anything they consider "improper", only notifying her afterwards, and are constantly dismissive of her career and efforts, even going so far as to threaten her with ambushing her with a "proper" husband that they choose for her if she doesn't hurry up and find one for herself. Small wonder she dreams about their empty heads rolling on the floor.
- Breast Plate: As shown in the page image, her armor highlights her breasts. In her case, it's far more justified in that female knights who have earned enough merits and accomplishments to have the ear of the king (not to mention be regarded as his favorite, based strictly on merit) are exceptionally rare, and her armor had to be custom-made, and it's still shown to be quite practical, effective, modest, and realistic.
- Cute and Psycho: An unusual variant in that she's at her cutest when she's at her most psychotic, though she's still adorable when she's pretending to be sane, she's adored by the fanbase when she's squeeing to Diablo about wanting to slaughter corrupt nobles and clergy, splattering their blood everywhere.
- Easily Forgiven: Despite her role in trying to awaken the Demon Lord, the main characters don't seem to hold a grudge against her.
- Evil Counterpart: She is what Shera would have been if she lost her innocence and idealism.
- Foil: To Shera. While both of them are highly intelligent, come from high ranking nobility, and struck out on their own to escape their extremely controlling families, Shera managed to hold on to her innocence and idealism, even willing to leave her home country behind forever to keep her freedom. Alicia was not so fortunate. Even after becoming a very highly lauded State Knight who has the ear of the king, due to many off-screen accomplishments and merits, especially since female knights are rare, she still cannot escape her parent's influence, insults, and belittlement. This has led her to become very bitter, jaded, and cynical, wanting nothing more than to eliminate the Six Races, including herself, although this may change after meeting Diablo, and seeing Krebskrum "born." It does. For the worse.
- Freudian Excuse: Her "noble" parents are smarmy control freaks that don't care about her happiness or well being in the slightest. They think her glasses, that she needs to see, are nothing more than "ugly hunks of metal on her face," and they routinely go through her possessions, "for her own good," destroying anything and everything they think is "improper." Then if she doesn't find a "worthy" husband of her own, why, they'll choose one for her. Small wonder she hates the six races, including herself. It becomes even more justified when we hear about the church of the Divine beings and how they raise their Paladins.
- Four Eyes, Zero Soul: Her true personality is this.
- Happily Failed Suicide: A Grey and Gray Morality example with a side of Deconstruction. Diablo stopped Alicia from slitting her throat open, but that didn't change the fact she didn't have a reason to keep on living anymore. After a bit of fumbling with his words, Diablo and his companions managed to convince Alicia to focus her anger on the people that actually wronged her by spying on the government for him with the (alleged) objective of gathering enough intelligence to either overthrow the Kingdom of Lyferia or destroying it outright at his convenience. Diablo knows he's exchanging an Omnicidal Maniac for a highly placed Mole and Turncoat, but hey, progress.
- Harmful to Minors: The anime explores her psychosis far more thoroughly. While she's unable to pinpoint a specific incident in her childhood that made her hate all the "mortal races," including herself, she is shown being exposed to "the darkness" of humanity as a child, with her parents thinking it's a damn fine idea, and like a frog put in water with the temperature being raised ever so slowly, irreversible damage was done before anyone noticed, including herself.
- Heroes Prefer Swords: Her weapon of choice is a sword.
- Heroic BSoD: She's visibly downtrodden when Demon Lord Krebskulm turns out to be a happy, innocent, little girl instead of an Omnicidal Maniac out to destroy the six races. She recovers when the Demonic Beings try to kill Krebskrum, happily coming to the little girl's rescue, when it would have been much easier to do otherwise.
- In Love with Your Carnage: What she loves most about the Demonic Beings is the sheer amount of damage and destruction they do, with little to no restraint, and is enamored with Diablo for the same reason. The fact that Diablo calls himself "a demonic king from another world" only serves to amplify this mindset.
- Internalized Categorism: Hates those of the six races and she includes herself in that number.
- Mask of Sanity: She's really good at pretending to be a kind, sane woman. She's really sociopathic and hates everyone, including herself.
- Meganekko: Wears glasses.
- Metaphorically True: She doesn't exactly lie to the king, but she does let him come to the false conclusion that Diablo is harmless and the reports of him taking down the 100 demonic being army are exaggerated by honestly reporting that Diablo is a chemical mage, a class of wizard universally considered weak, and there are many Demi-humans at Faltra that honestly respect Diablo. This is something Diablo, Rem, and Shera asked of her because they don't want to be pawns of the human kingdom.
- Mistreatment-Induced Betrayal: In Volume 4, we learn more about the reason for her hatred of the six races. She was forced into becoming an Imperial Knight, and endured a great deal of off-screen humiliation in the process, as a token female knight. Her hatred just kept on building over the years until she snapped, and wanted to end it all.
- The Mole: For the Demonic Beings.
- Nothing Personal: As she's handing Rem Galleu over to Saddler, she happily admits that she wouldn't mind taking Rem's place if her death "awakens" Krebsckrum with hatred instead.
- Principles Zealot: She is obsessed with the principle that nothing should be left half-finished. Ergo, if she's witness to corruption in the Capitol, she wants to burn the whole kingdom to the ground. If she's guilty of a betrayal, regardless of the reason, she tries to kill herself.
- The Quisling: Is actually allied to the Demonic Beings.
- Royals Who Actually Do Something: She is the daughter of a duke house.
- Stepford Smiler: Her smile is completely fake and plastered on. Diablo, as socially inept as he is, ironically, is the only one, at least the only one sane, who sees through it.
- Teach Him Anger: An unusual positive example, all things considered. After discovering her real plans, Diablo's group manages to convince Alicia that trying to exact revenge on all the Six Races is wrong. However this takes away her of most of her will to live until Diablo's questionable wisdom teaches her to focus her anger on the people who actually wronged her and made her lose her faith in humanity: her parents and the corrupt nobility of Lifelia.
- This Is Unforgivable!: Both Rem and Krebskrum find her betraying them into Saddler's hands an unforgivable offense, and with good reason. Though Diablo can't bring himself to forgive her either, he also can't bring himself to outright hate her because he remembers all the good she's done for the team before, and suspects that she's trapped in complicated circumstances like Shera was under Keera.
- Undying Loyalty: In exchange for Diablo and Krebskrum's aid in healing Edelgard, she first offers to take her own life, when Diablo prevents that, she willingly devotes her life to his service. It doesn't hurt that she interprets Diablo's words as seeking to root out and destroy the corruption of the kingdom she hates, even if it ultimately means overthrowing the kingdom in the process.
- Villainous Friendship: With Edelgard. The two are very close, and if push comes to shove, both are willing to lay their lives down for each other.
- Would Not Hurt A Child: Even if it was part of a larger agenda, Alicia repeatedly pleaded with Saddler and his troops to not harm Krebskulm. The scoundrels went ahead and tried anyway.
Royal Palace Chivalric OrderAn adventuring group commissioned under the king. The seven best of them are called the "Seven Heroes".
Marquis Maximum AbramsThe Human leader of the order.
- An Offer You Can't Refuse: Deconstructed. At the end of Volume 10, he "convinces" Diablo to go meet with King Delouche by pointing at Horun, Lumachina, and a few others saying "You won't refuse." Diablo's response is to admit to Sylvie that Maxim is completely untrustworthy and to make sure Maximum can't go around taking hostages.
AllenA Dwarf member who loves to fight.
- Blood Knight: Loves to fight.
- Named After Somebody Famous: In-universe, he is named after the hero who defeated the Demon Lord.
ThanatosAn Elf member who says he is immortal.
- Exactly What It Says on the Tin: As revealed at the end of Volume 10, he's got some kind of ability that makes killing him and keeping him dead rather difficult.
- Leeroy Jenkins: Once he identifies an "evil" target, he's got a tendency to rush in without plans, preparation, or back-up. Fortunately, Diablo had backup prepared, or his carelessness would have cause the Royal Capital to be destroyed in volume 10.
- Nice Job Breaking It, Hero!: In volume 10, he scuppers Diablo's plan to deal with Evil god Europa by carelessly attacking and activating its near-impenetrable shield.
- Red Baron: Known as "Thanatos the Immortal".
MerciA student at the Magic Academy. Her Cross Reverie counterpart was a nameless NPC 《Flower Vendor》 who would be one of the sacrificed students to summon Destruction God Europa.
- Cat Girl: She is a Pantherian.
- Charm Person: She can use 《Hypno》 magic. By having direct skin contact with her target for 30 seconds, she can then cast the spell to make them fall under suggestion for 3 minutes. She uses her magic to make her clients believe they had sex with her and take their money.
- Hoist by His Own Petard: Not knowing about Diablo's Magic Reflector, she gets hit with her own "Hypnosis" magic.
- Honey Trap: Combined with False Rape Accusation. The actual reason she sells flowers on street corners is to use hypnosis magic to lure men into a compromising position and then blackmail them. Diablo lampshades how idiotic and dangerous such a ploy is.
AngelineA human who is the student council president at the Magic Academy.
- Bare Your Midriff: Her outfit exposes her belly. Hardly practical for a desert environment like Zirconia town.
- The Baroness: Lamnites is a tough, military woman who prefers to fight adversity head-on and doesn't believe in running away. She later shows a seductive side around Diablo in private, being unashamed of using her body to convince Diablo to remain in Zircon Tower.
- Chocolate of Romance: She offers Diablo some chocolate as an excuse to kiss him. She succeeds
- Flat-Earth Atheist: She lives in a world with magical monsters, priests who manifest actual miracles by prayer, and actual "demonic beings", which the lore on both sides claim to exist as a direct result of a proxy war between "Kami-sama" and the Demon Lord, and yet, she doesn't believe the divine beings exist, even going so far as to threaten Lumachina with deadly force because, by her mindset, if "Kami-sama" exists, he'd instantly manifest to protect Lumachina from a gun attack.
- Jerkass: She is not a nice woman, to say the least.
- Jerk with a Heart of Gold: Though subtle, she's not AS bad as a person she appears to be. She has shown concern for the well being of the men under her command and even begged for someone to come and help her soldiers. After the battle with Vanaknes and his army was over when Rem asked if they could use the chapel to cure people of the local magical disease as well as pay the rent, Lamnites refuses. Not because she doesn't want to let them use it, but because there's no way she could make the people who showed up and turned the tide of the battle pay rent, saying she was very grateful and told Diablo's party that they and the priests can use the chapel rent-free.
- Mage Marksman: A sub-specialist of archery, she fights with magically empowered guns.
- Nerf: Inverted. In the game, Cross Reverie, the magic gunner class is so overpowered that it got nerfed, a lot. Diablo suspects that her version is the "original" form, and thus would be very hard to face against, even at his prime.
- Only in It for the Money: All she cares about is collecting her taxes. While she does protect the town from powerful rampaging demonic beasts, she does it so the tax revenue keeps flowing.
- Proud Warrior Race Guy: The only thing of merit in her mind besides money is fighting potential. She has zero respect for the Church of Celestials and the King of the Lyferia kingdom because she sees the church either bully the weak, or be entirely non-combatant, and because she finds the king "cowardly" as he never visits her danger-prone city himself.
- Sex for Services: After Diablo near single-handedly stops an assault from an army of powerful Fallen, Lamnites decides to keep him in her city even if it means having to seduce him into staying. She hints to have slept around in the past to solidify her position, but she gets interrupted before she could go all the way with Diablo.
- Absolute Cleavage: How does she keep that outfit on?
- Crouching Moron, Hidden Badass: She acts like a ditzy tease, but she can give Diablo a hard fight in head-on combat, as she can either dodge or outright redirect all but his flashiest spells, and can close quarters, past his defenses, if he tries to actually activate them.
- Honor Before Reason: She will honor her end of a contract to the letter, regardless of the consequences. Even if it means Rem dies, or worse, her holding Diablo captive allows Geibalt to start a forest fire, on a mountainside, dooming her home town, and her entire clan.
- Insistent Terminology: Insists on being called "Onee-san" (Big sister) not "Oba-san" (Aunt), despite knowing full well she's Rem's aunt.
- Kung-Fu Wizard: As one of the top members of the Gaido clan, she fights with Supernatural Martial Arts that also add magic-like effects.
- Really Gets Around: Implied during a training session with Diablo when complimenting him on his...size. Shes also the first woman so far that has managed to please Diablo without getting interrupted, instead of Diablo unintentionally getting her off or having someone barge in and spoil the moment like in his previous interactions with other women. She still failed to sleep with him, though.
- Shameless Fanservice Girl: She knows she's hot and doesn't hesitate to flaunt it.
- The Tease: Constantly, and it doesn't matter if the target is male or female.
