Demon King's Army
Demon King
The Demon King
The leader of the army threatening the safety of the world, and the one that Kazuma and the gang (supposedly) seek to defeat. A mysterious figure, his presence is felt in nearly every dangerous encounter the main characters face.
- Beleaguered Boss: As it turns out, most of his generals are eccentric and often unpleasant company, and a large part of his job is making sure that they get along and don't accidentally sabotage his efforts.
- Benevolent Boss: He was pretty cool with Wiz being a shopkeep, as long as she continues keeping her part of the barrier up. Played with, as it later turns out that she was stealing magical items from his treasury to sell, so it may have been less this and more him giving in so she can stop giving him headaches.
- Big Bad: Is this for the entire world, but also for the main party. Though they occasionally forget about that goal.
- Contractual Boss Immunity: Kazuma and Eris assume that as the Final Boss, he's immune to One-Hit Kill skills or Standard Status Effects. However, Aqua can debuff him enough for Kazuma to manage a 1-on-1... after she's reminded that she has the godly power to do so.
- Demonization: The Axis Cult makes it their duty to make sure the Demon King is the enemy of mankind, even spreading straight up Malicious Slander to get on his bad side.
- Even Evil Has Loved Ones: He seems to be fond of his daughter, who is one of his generals. When Kazuma uses "Steal" on him, he accidentally steals a handmade handkerchief made by her, and he flies into a rage after Kazuma callously throws it away.
- Evil Old Folks: By his own admission, he's well past his prime.
- Evil Overlord: Seems to be a pretty classic example of this.
- Fair-Weather Friend: Wiz and Vanir see him as a boss and nothing more, and when Kazuma tells them he's going to the Demon King's castle and may confront him, they simply wish him well. They believe that fighting heroes who challenge him is part of the Demon King's job description, and if he is defeated he simply wasn't powerful enough to hold his job.
- Given Name Reveal: His true name is finally revealed in the last chapters of the Web Novel and Light Novel: Kouichi Sakaguchi.
- Hidden Villain: Most of what we know of him is second hand knowledge. However he is usually connected to every odd event the party finds themselves messed up in. In particular he is looking for Aqua, wary of the "great light" that descended upon the world.
- Honor Before Reason: Eris convinces Kazuma to Teleport himself and the Demon King into a dungeon. The King could easily Teleport back to his castle to pick off Kazuma's allies, but his pride stops him from abandoning a one-on-one against a low-level Adventurer.
- Horned Humanoid: His pair of horns are noted as his only inhuman trait.
- Maou the Demon King: Obviously. He prefers to let his men do the heavy lifting, though.
- Meaningful Name: It's actually a pretty common one with no important meaning, but in the context of this world it is pretty significant, because it is a Japanese name. According to the guy himself, he is aware of Japan, but never was there since he's a demon. In the original Web Novel version of the story, he actually was from Japan and was another one of the people sent to that world by Aqua and used his cheat item to take over that world.
- Mook Depletion: By the time they storm his castle, Kazuma and his companions have killed five of his eight generals (Verdia, Vanir, Hans, Sylvia, and Wolbach; the survivors either stopping actively supporting him or lost their powers), one candidate for the position of general (Duke), and had obliterated a large portion of his army.
- Mook Promotion: This is his greatest power, the ability to turn any generic monster into a formidable foe just by being near them.
- Orcus on His Throne: Despite his generals being destroyed or turned against him thanks to the actions of the "Billionaire Adventurer" and Axel Battle Harem, the Demon King does nothing except send more lieutenants to investigate the problem... who get defeated yet again.
- Sane Boss, Psycho Henchmen: Played for laughs, as is typical for the series. When Kazuma has his final showdown with the Demon King, they share a brief moment of camaraderie when the latter mentions what a headache his so-called Demon Generals were. To whit, Wiz often stole things from the castle armory to stock her "shop" (due to her long-standing desire to be a shop-keeper), Vanir enjoyed winding people up to savour their negative emotions, Verdia was a Covert Pervert despite his knightly ways... This was part of the reason why the Demon King was perfectly content to allow Wiz to leave and set up shop in Axel so long as she continued to maintain the protective barrier around his castle: it was just one less headache for him to deal with.
- Villains Want Mercy: When he sees Kazuma ready to fire off an Explosion that will kill them both (and there will be No Body Left Behind for Aqua's Resurrection), he tries falling back on Kazuma's offer to call the fight a draw and return to his castle together, but Kazuma doesn't trust him because he wasn't willing to accept the draw offer before he realized his life was at risk. The Demon King then tries to entice him with more information on his background, but Kazuma bluntly says that he doesn't care and fires the spell.
- We Can Rule Together: Having seen Kazuma's cunning and resourcefulness first-hand near the end of their fight, he offers the adventurer a chance to join his army, but is upfront about Kazuma needing a curse of loyalty put on him as a condition.
- Weak, but Skilled: Individually, he's not much more powerful than one of his generals, and he's well past his prime. His true threat lies in buffing his generals to the point of basically having no weaknesses, and any monsters near him into a Praetorian Guard.
Beldia
Beldia
The first general of the Demon Army encountered by the party, or at least the first to publicly proclaim themselves as such. Kazuma and Megumin accidentally provoked him when Megumin unwittingly used his castle to practice Explosion. Exceptionally durable and a skilled swordsman with a menacing appearance to boot, he is in every way a quintessential noble villain, or so it would seem.
- Absurdly Sharp Blade: His greatsword went through adventurers' armour like a hot knife through butter, until he fought Darkness.
- Affably Evil: He's a villain, but he was willing to leave the town of Axel alone because his sense of honor means he wants to avoid fighting weak enemies. He was initially willing to forgive Megumin for hitting his castle with explosion spells, until she refused to stop.
- Anti-Magic: His armor was supposed to be this, but it wasn't as effective against Aqua because she's a goddess. Still, it was pretty good since her Turn Undead spell is normally a One-Hit Kill and he withstood multiple blasts of it, along with Megumin's Explosion and a massive deluge.
- Arc Villain: For episodes 3-6 of the anime. He was perfectly content to just sit back in his castle until Megumin started using it for Explosion practice.
- Back from the Dead: In the Season 2 tie-in platformer, he somehow revives himself to take revenge on Kazuma and his party, but particularly Kazuma himself, who the general has come to see as a Worthy Opponent. After being defeated, he has a surprisingly respectful moment with his nemesis... Before Aqua spoils the mood by killing him again out of the blue. Poor guy can't get a break.
- BFS: Wields a massive greatsword with ease.
- Big Bad Wannabe: Oh, how he tried! Beldia clearly wanted to be seen as a villain, in keeping with his role as a Demon General. Kazuma's party however, fail to take him seriously at all.
- Bitch in Sheep's Clothing: Yes. Even a Noble Demon can get this. Despite being quite pitiful in nature, he's one of the few people to have a confirmed kill... and he is directly responsible for Wiz being forced to abandon her humanity.
- Card-Carrying Villain: Beldia plays his role as Demon General straight to the hilt, setting up shop in a decrepit castle and daring adventurers to attack him when his warnings are ignored. When he shows up a week later, he angrily complains that no one bothered to attack him; the manga reveals that he was actually eagerly awaiting an adventuring party, going so far as to have his minions set up a banquet in anticipation.
- The Comically Serious: He tries to come off as threatening, but his Large Ham tendencies and the goofiness of the situations around him turn him into this.
- Covert Pervert: Despite his claims of not being a pervert, he really is one, as Wiz revealed that he would peek up her dress by rolling his head under it. However, he is still not at the level of Darkness.
- Curb-Stomp Battle: Easily cut down a group of unlucky adventurers who tried to fight him.
- Damage-Sponge Boss: It required an Explosion, Sacred Create Water, and three castings of Sacred Turn Undead to defeat him.
- Even Evil Has Standards:
- Was disgusted when he believed that Kazuma's party would just let Darkness die. He then found out that Kazuma's party had no reason to attack, since Darkness was cured minutes after he cursed her.
- Despite his aforementioned perversion, he is repulsed by Darkness' penchant for masochism and her captivity fantasies.
- Giant Eye of Doom: When he throws his head into the sky to execute his Flash Step combat technique, it creates an effect that looks like the Eye of Sauron.
- Headless Horseman: As befits a Dullahan. Even his horse is headless.
- Humiliation Conga: His castle becomes daily target practice for Megumin's Explosion, he loses his entire army of undead to her, and is repeatedly hammered by Turn Undead and water spells. Also, all his acts of villainy are easily reversed by Aqua and he is ultimately dispatched when his head is stolen by Kazuma. He also ignores his plea to give him his head back and uses it to teach the townspeople to play soccer, leaving his body inactive and defenceless.
- Kill It with Water: Dousing him with water decreases his defense and causes significant damage.
- Knight of Cerebus: Subverted. He certainly seems like a serious opponent initially, but the fight with him, despite being tough, is still full of silliness.
- Large Ham: Bombastic in speech, as part of his apparent attempts to play up his villain persona.
- Lightning Bruiser: Fast, hard-hitting, and tremendously resilient to damage (he survived Megumin's explosion spell).
- Noble Demon: He was once a noble knight and follows a code of honor. He came to Axel to investigate the mysterious holy aura that suddenly appeared (Aqua), and was perfectly willing to leave the newbie adventurers in the town alone if they'd just stay out of his way. He was surprisingly reasonable about being continually harassed by Megumin, but snapped after having to deal with the party's antics for too long.
- Noodle Incident: Nobody knows what was he doing in the castle, though it is implied that he was attracted to Aqua's presence.
- Reasonable Authority Figure: Not a legitimate authority figure, but serves as a general in the Demon King's forces and is probably Axel's feudal lord from their perspective. He also shows a shocking level of patience towards the group (more than they usually get from allies, let alone each other), giving them every opportunity to resolve the situation without violence.
- Red Baron: The Hero Slayer.
- Super-Toughness: He survived Aqua's Turn Undead and its stronger variant, and a hit from Megumin's explosion spell. He only dies after his defense is weakened from Aqua dousing him with water.
- This Cannot Be!: Numerous times in the final battle.
- Villain Has a Point: Rightly states he wasn't giving Axel any trouble, and that Megumin had been blasting his castle anyways. That point is a bit undermined by the fact that he was keeping monsters - and, thus, adventure jobs - away from the town by his sheer presence, though given that adventurers solve threats, that's still debatable.
- Villains Want Mercy: After Kazuma got his hands on Beldia's head.Beldia: Ex, excuse me... Can you.. return my head back to me...?
Kazuma: Hey everyone, let's play soccer! Soccer is... Soccer is—! A game that forbids the use of hands and only using your feet to control the ball—! - Wake-Up Call Boss: He is very competent and requires teamwork to be brought down, though he does not become a Knight of Cerebus.
- Was Once a Man: He was once a noble knight who was unjustly beheaded, with his grudge tethering him to the world and reanimating his corpse.
- Weaksauce Weakness: He's weak to holy magic because he is an undead. In practice this is partially why he's weak against Aqua.
- Worthy Opponent: As a Dullahan, a noble undead knight, he greatly respects Darkness, a crusader... if only she would stop talking, because her masochism weirds him out.
- In the Season 2 blu-ray tie-in platformer, he comes to see Kazuma as this as well.
- Your Mind Makes It Real: His death curse magic works this way. You have to hear the manner of your death, and believe it. If you do, your death prophecy comes true, unless Beldia is destroyed first or the curse is broken by holy magic.
Wiz

Hans
Hans
The primary antagonist of Volume 4, and a general in the Demon King's army.
- Adaptational Badass: In the novels, he's blown to bits by Megumin, then said bits are frozen and shattered by Wiz. In the anime, he survives all this, instead reduced to a diminutive state that would regain his full size if he ate enough people. It takes Aqua empowered by her Axis Cult to finish him off.
- Arc Villain: He's the villain that Kazuma's party faces in Volume 4, which is adapted in the last episodes of season 2.
- An Arm and a Leg: After Wiz freezes one of his arms to restrain him, he simply hacks off the limb to free himself. This hardly bothers him as a slime monster, though, because Good Thing You Can Heal is in effect for him.
- The Bad Guy Wins: Because Aqua used God Requiem to defeat him, Alcanretia's hot springs were purified into regular hot water, rendering them useless to the town as a source of income. Thus, he technically accomplished his mission from the Demon King despite falling in battle. Later on however, it's revealed that the springs didn't simply turn into hot water, but hot holy water. In the novel epilogue, it's mentioned that they had amazing effects like healing injuries, and damaging undeads, and would produce much greater profit than the hot springs.
- Big Eater: He feels an instinct to eat compulsively and has no qualms about indulging himself.
- Blob Monster: He's a Slime — specifically, a Poison Slime — so his natural form is a mass of toxic purple goo that can morph its semi-liquid body as he likes.
- Damage-Sponge Boss: First Megumin cast Explosion on him. He survived it. Then Wiz cast Cursed Crystal Prison on him. He survived it. Aqua used God Blow. He survived it. It ultimately took a fourth super attack, a maximum strength God Requiem, to finally kill him.
- Does Not Like Spam: While he can eat just about anything, he has a particular distaste for the soap used by the Axis Cult, likely because they kept forcing it on him while he was undercover.
- Extreme Omnivore: Of the "can eat anything" variety.
- Feral Villain: Once he reverts to his true slime form, he's only driven by instinct to eat everyone around him.
- Good Thing You Can Heal: He can repair any damage to himself by eating.
- The Goomba: Subverted. You'd think that like in dozens of RPGs, a slime like him would be this, or at least a Metal Slime. Instead, he is a really competent and dangerous villain who serves as one of the Demon King's generals.
- Grimy Water: His poison turns the hot springs in Alcanretia into this. Once polluted, only Aqua can touch the water without getting killed, and even then, it causes her immense pain.
- Humans Are Insects: Sees humans as nothing more than an annoyance, on a good day.
- Kill and Replace: He did this with the manager of the hot springs, as he's done with countless other victims, much to Wiz's anger.
- Kill It with Ice: As a Muck Monster, he is invulnerable to physical attacks and simply shrugs off most magic. It takes having his liquid body frozen by Wiz to incapacitate him.
- Literally Shattered Lives: After being frozen by Wiz, he is subjected to this in an attempt to finally eliminate him. It's averted, however, when it turns out that this only blew off most of his mass, and he still managed to survive, albeit in a diminished state.
- Madness Mantra: In the movie when Sylvia nearly dies and meets the souls of Hans and Verdia, Hans keeps repeating soap and how he's clean, obviously traumatized.
- Muck Monster: He is actually a sentient slime monster who works for the Demon King and is on a mission to poison Alcanretia's hot springs to deprive them of their source of income.
- Not Quite Dead: After revealing that he survived being frozen and shattered, Hans seemed poised to consume everyone present and heal himself. It takes Aqua being augmented by the faith of the Axis Cult to finally defeat him.
- As revealed in the second Continued Explosions Spin-Off,note he survived Megumin's explosion, though greatly weakened and suffering from amnesia. Though Megumin also seems to have forgotten who he was, and finishes him off with another explosion soon after he regains his memories.
- Not-So-Harmless Villain: While he is only a slime, it was a really bad idea for Kazuma to underestimate him. In battle, he tanked Megumin's Explosion with little ill effects and was capable of making Wiz expend all of her magic power. Despite that, he still remained standing, albeit in a diminished state. It takes Aqua's God Requiem, augmented by the collective faith of the Axis Cult, to finally defeat him. Were it not for that, he would have devoured everyone present and easily regained his power and size again.
- Person of Mass Destruction: He could have very easily wiped out the entire city of Alcanretia by himself, or at the very least made it inhospitable for a long period of time.
- Poison Is Corrosive: His toxins are capable of dissolving rocks, as well as flesh and muscle, as Kazuma can attest to.
- Poisonous Person: He is highly toxic and corrosive in his true form.
- Too Dumb to Live: It was a pretty bad idea to mention that he ate a person in front of Wiz, a powerful Lich who does not tolerate civilian casualties.
- To Serve Man: On a bad day, he eats people. Not that he needs to.
- Villainous Breakdown: He has a hugely epic one after Wiz's Berserk Button was pushed.
Sylvia
Sylvia
The primary antagonist of Volume 5 and "Legend of Crimson". A chimera that goes after the Crimson Clan village to seize a weapon of doom for the Demon King.
- Adaptational Badass: In the light novels, she meets her demise when she gets shot by the fully charged weapon that she was specifically weak to. In The Movie, she manages to survive this blast and brings Verdia and Hans back to life, assimilating them in the process. It ultimately takes the combined efforts of the main cast, Vanir, Wiz and the entire Crimson Demon Clan to put her down.
- Adaptational Curves: She is described as having a modest sized chest in the light novel. In the anime, her breasts are larger than most characters' heads.
- Adaptational Nice Girl: In the anime, she gets some added moments where we see she genuinely cares for her minions, praising them for their devotion against the Crimson Demons. After fusing with the Mage Killer, she even saves them from a barrage spells that would have killed them.
- Adaptational Skimpiness: In the light novel and manga versions of the story, while her dress does get damaged in the centipede transformation, it remained mostly intact. In the anime move, the dress gets destroyed, leaving her with several scales covering her breasts in the form of a halter top and goes up another level in skimpiness in her next transformation with each of her breasts being just covered by one scale.
- Affably Evil: She genuinely likes Kazuma, and in the anime is a Benevolent Boss. Pity she is also an Ax-Crazy murderer.
- All Your Powers Combined: Her ability to fuse herself with anything gives her this but it's especially in effect when she assimilates Verdia and Hans from the brink of death, not only resurrecting them but also giving her access to their powers.
- Anti-Magic: She was stationed as the Demon King Army Boss in charge of subjugating the Crimson Magic village due to her very high magic resistance, even placing herself in front of her troops to block incoming spells. Not that it helped them much. Gets much worse once she fuses with the Crimson Clan's anti-magic weapon.
- Arc Villain: She's faced and defeated by Kazuma's party in Volume 5, which is adapted into The Movie.
- Artificial Human: While she appears humanoid, she is in fact an artificially-created construct.
- Assimilation Backfire: In "Legend of Crimson", she absorbs a willing Kazuma into her form. However, doing so allows Kazuma to lower her barrier, letting Megumin and Yunyun blast Sylvia and Kazuma into dust. Lucky for Kazuma that Aqua can bring him back to life.
- Ax-Crazy: Kazuma suspects that she was driven off the deep end by dealing with the Crimson Magic Clan so much. When she finally gets to launch a real assault on the village after assimilating with the "Mage Killer" she completely loses it. The constant taunts, over-the-top speeches, and Teleport Spam only makes her more unhinged.
- Barehanded Blade Block: Kazuma's rage over her interrupting his bedtime with Megumin comes to an abrupt end when she nonchalantly stops Chunchunmaru with two fingers.
- Benevolent Boss: In the anime, Sylvia doesn't treat her army as expendable tools. She is very fond of her minions, both praising them for their dedication and shielding from Crimson Demons in combat. Minions, in return, just adore her.
- Berserk Button: Traitors really set her off.
- Buxom Beauty Standard: Kazuma ends up enjoying it when Sylvia takes him hostage because she sandwiches his head right in between her big boobs.
- Came Back Strong: In the movie, Sylvia is blasted with the Railgun and almost dies, but her Near-Death Experience causes her to somehow fuse with the souls of Beldia and Hans. She then resurrects herself as a giant monster that's a combination of a chimera, a dullahan and a poisonous slime.
- Dies Differently in Adaptation: In the light novels and manga, Sylvia is killed when she's shot with the Railgun designed to destroy the Mage Killer. In the movie, on the other hand, Sylvia survives the Railgun's blast and fuses with Beldia and Hans. Through Kazuma's strategy, she's killed by a Combination Attack from Megumin and Yunyun.
- Even Evil Has Standards: She's appalled at how quickly Kazuma gives her access to the Mage Killer before she even starts trying to seduce him after her Unsettling Gender-Reveal.
- Fusion Dance: She has the ability to fuse herself with any monster or magic item she deems "interesting." Her entire goal in raiding the Crimson Magic Clan village was to do this to a weapon called "Mage Killer" developed by the same guy that made the Mobile Fortress Destroyer to eventually wipe out the Crimson Magic Clan that the Demon King saw as a threat. In The Movie, she merges with the souls of Verdia and Hans, achieving a new form altogether.
- General Failure: Her plans to defeat the Crimson Demons consist of launching Zerg Rush after Zerg Rush that ends with her minions slaughtered by the Crimson Demons' powerful magic. In the anime, her minions actually love in spite of this, and she thanks for their dedication despite sending them against the Crimson Demons. And even then she only got the Mage Killer, it was only because Kazuma panicked and vault it was kept in.
- Hermaphrodite: Thanks to her Fusion Dance abilities, she has body parts from both genders, much to Kazuma's dismay. She casually mentions that the girl parts specifically were added later.
- Hoist by Her Own Petard: Ultimately, the only reason she loses in The Movie is by her fusing with Kazuma and him using the opportunity to bring down her barrier at the right moment.
- Hybrid Monster: In the movie, due to fusing with Beldia and Hans, she turns into a chimera-dullahan-slime monster.
- I Have You Now, My Pretty: Took Kazuma hostage when he and Megumin confronted her during her midnight raid on the village. Partly to taunt and frustrate Megumin and the others, and partly because Kazuma was her type, she even used Bind to tie him to her and made her escape with him in tow. Subverted in that she actually let Kazuma go once she had her fun to pay him back for him letting her go the day before. Although once she found out Kazuma could open the door to the mysterious building that not even her top-tier Barrier Killer could breach she pulled this again to get him to open the door...by promising him pleasure. While she meant it to be gentle persuasion instead of a threat, Kazuma instantly opened the door as he had learned all too well by this point that she had guy parts downstairs. She was actually pretty put out that he caved so fast before she could even do anything.
- I Just Want to Be Loved: To the point of being a Fatal Flaw in the movie. Kazuma plays her like a fiddle by exploiting this trait of hers but even when she's dying she announces that despite Kazuma toying with her feelings, she still loves him.
- The Juggernaut: After fusing with the "Mage Killer". She's very, very tough, virtually nothing could slow her down in the slightest.
- Lady in Red: She's a very sensual and buxom woman wearing a form-fitting red dress.
- Love Makes You Dumb: Kazuma takes advantage of her desperation for love beyond her goblin soldiers by willingly merging with her and flirting to make her lose focus on her barrier, allowing Megumin and Yunyun to finish her off. She goes out declaring that she still loves him even after he toyed with her heart.
- Marshmallow Hell: Subjects Kazuma to this. He initially likes it until he learns she is a Hermaphrodite.
- Mix-and-Match Critter: She's a chimera, with the powers and abilities of many different monsters.
- No-Sell: Kazuma charges at her with his sword in a blind rage, only for her to stop the attack cold by using two fingers to grab his sword. He clearly realized how screwed he was.
- Not-So-Harmless Villain: Comes as an inept General Failure, launching human wave tactics against the Crimson Demons, which only get her minions slaughtered and send her running scared. Then she merges with the "Mage Killer" weapon, and almost single handedly wipes out the Crimson Demons.
- One-Winged Angel: In the anime, after being blasted and nearly dying, she fused with the souls of Verdia and Hans, turning into a giant amalgam of all three villains with all of their powers.
- The Power of Love: In the Movie, she creates a barrier powered by Love, Hope, and Dreams to block Yunyun and Megumin's super-charged combination attack. It would have held out against it entirely, had Kazuma not lowered it.
- Rage Breaking Point: As if she didn't have a grudge against the Crimson clan to begin with, their Teleport Spam trickery made her go completely batshit crazy with rage.
- Sexy Slit Dress: She wears a sexy red dress with a long slit showing her left leg.
- Statuesque Stunner: She's so tall that she has to pull Kazuma well off the ground for his face to just reach her cleavage.
- This Is Going to Suck: Once she realized that Megumin's "ultimate attack" wasn't just for show like everyone else, and the one weapon that could kill her was fully charged, and about to be fired upon her.
- Universally Beloved Leader: In the anime. She treats her underlings with kindness and respect, and they are completely devoted to her inspite of her use of them in futile assaults on the Crimson Demons.
- Unsettling Gender-Reveal: Kazuma is thrilled about getting Marshmallow Hell from Sylvia until she casually reveals she has male body parts too and Kazuma realizes one of those parts is poking him from behind.
- Villainous Crush: She fell in love with Kazuma, The Protagonist. In the Movie, upon realizing that Kazuma only merged with her to bring down her barrier, she admits that, although betrayed, she still loves him.
Wolbach
Wolbach
A woman Kazuma first meets in the Axis Cult town of Alancretia. She's actually a master wizard/possible Physical Goddess, general of the Demon King's Army, and the one who taught a very young Megumin explosion magic.
- Affably Evil: She's very calm and polite, never initiating violence against Kazuma, at least not intentionally. If he's collateral damage on her target though...
- Alas, Poor Villain: Despite being their enemy, Kazuma, Megumin and Yunyun all feel bad about having to fight her since she was a friend to each of them at some point in the past, and the only real reason they're fighting is because they're nominally on opposing sides. Even to the bitter end, Kazuma tries to convince her to stand down so they don't have to kill her.
- Animal Motifs: Cats. Naturally befitting of the 'self-proclaimed' goddess of Sloth and Violence.
- Arc Villain: She's the general that faces Kazuma's party in Volume 9.
- Bathing Beauty: Kazuma meets her when she's enjoying a bath at a hot spring and he very much enjoys the sight of her nakedness. Not only that, but she actively seeks out saunas to bathe in.
- Boring, but Practical: Her primary tactic is walking up to the target, unleashing Explosion from a distance, and then teleporting away before the target can retaliate.
- But for Me, It Was Tuesday: Combined with Forgotten First Meeting. Despite remembering Yunyun, and being constantly questioned by Megumin, she claims to have no memory of their meeting wherein she subdued her other half after Megumin accidentally unsealed it.
- Buxom Beauty Standard: Her massive breasts are eye candy for Kazuma and an object of envy for the flat-chested Megumin.
- Chekhov's Gunman: She appears at first as a random background character in Alcanretia, and the only indication of her being a member of the Demon King's army was that Hansnote was casually chatting with her. Her actual status wasn't revealed until Volume 9: Five volumes later.
- Contrived Coincidence: If Kazuma walks into a sauna, no matter how remote the location, he's going to encounter her. It doesn't work if he's expecting it, however.
- Create Your Own Hero: She taught Megumin about the Explosion spell and became her inspiration to single-mindedly devote herself to said magic. When they meet again after years, Megumin uses the Explosion spell to kill Wolbach.
- Doppelmerger: Wolbach and Chomusuke were originally the same entity, but they were split after being sealed. At the end of Volume 9, Kazuma hypothesizes that Wolbach has been absorbed into Chomusuke, her other half, after her defeat, given that the cat was now more receptive to baths and responded to Kazuma calling her "Wolbach".
- Fatal Flaw: Her domain of Sloth proves to be her undoing. When Kazuma's party gets involved in the defense of the fortress she's attacking, she's too slow to pick up on how dangerous they are, and as a result they turn what was initially a long-drawn out Curb-Stomp Battle in her favor into a sudden comeback victory for humanity. Even after she picks up on how dangerous Kazuma is and decides to personally target him, she still underestimates him and gets a face full of dynamite for her trouble. Her death ultimately comes about because Megumin is able to instantly cast Explosion, allowing her to cast before Wolbach can finish the chant for her own.
- A God Am I: Wolbach calls herself the "Goddess of Sloth and Violence" and claims that the Axis Cult named her an "Evil God" on their own volition. Naturally, she and Aqua have a rather heated argument about the whole thing.
- Horned Humanoid: Wolbach is seen to have goat-like horns protruding from the sides of her head while serving as a Demon King's General, although whether or not these are natural or are merely decorative items is unknown.
- It's Personal: She initially has no grudge with Kazuma and his group, offering to let them go repeatedly if they would just stay out of her way. That all changed when she realized Kazuma was directly responsible for the defeat of several Demon Generals whom she considers True Companions. The circumstances of the battles don't matter to her.
- Ms. Fanservice: She's a beautiful woman with very large breasts and is repeatedly shown bathing.
- Mugging the Monster: Threatens Aqua with "divine retribution" for mocking and impersonating a god, and calls the Axis Cult insane to her face.
- Naked First Impression: Kazuma meets her in a sauna at Alancretia while she's bathing in the mixed baths, speaking with Hans. At that point in time, Kazuma was a perfect gentleman, and complied with the proper mixed-bathing etiquette, to the letter. (Though since he spent the entire time staring at her, it's clear he didn't respect the spirit.)
- No Body Left Behind: Even with the firepower of Megumin's Explosion, Kazuma finds it odd that a General would be destroyed without a trace. Some later changes in Chomusuke's behavior imply that she was asssimilated into her other half.
- Noodle Incident: At some time in the past, she met another Satou who was also a legendary hero opposing the Demon King. She thinks the two of them are related. Kazuma has no idea what she's talking about. It's entirely possible that Satou was the legendary loner hero who fought then became the Demon King.
- Only Sane Woman: Both Kazuma and the Demon King consider her the only General with a proper head on her shoulders.
- Pet the Dog: Multiple:
- The first was when Megumin was a young girl, and she saved her from a large and feral Chomusuke, then, in return for freeing her, taught her Explosion magic.
- The second was after Yunyun left Axel, and she offered to become Yunyun's companion.
- The next happened in the two times she and Kazuma met in a hot spring, and they listened to each other's problems.
- Pointy Ears: She has pointy elf-like ears.
- Punch-Clock Villain: She really doesn't have a grudge against Kazuma's party; she's just attacking certain strategic targets under orders from the Demon King, at least until the It's Personal entry comes to bear.
- The Scapegoat: After her seal is broken, the adults of the Crimson Magic Clan are quick to blame anything they mess up on her.
- Screw This, I'm Outta Here: The moment she realizes Aqua is the real deal, she teleports away, right as soon as Aqua finishes casting her mightiest spell.
- Stuff Blowing Up: Like Megumin, she also uses the Explosion spell.
- Teleportation: She knows the Teleport spell, which she used to basically escape whenever she exhausted her mana using Explosion magic.
- Unknown Rival: She greatly resents Aqua due to the Axis Cult branding her as an "evil god" in the distant past and ruining her reputation as a legitimate goddess. Aqua, for her part, claims to have never heard of a minor goddess by the name of "Wolbach," and continues to dismiss her as being weak and useless even after noticing what little divine essence Wolbach had left.
- Villains Out Shopping: She enjoys going out to frequent hot springs, especially the ones in Alcanretia. At first she claims that it's to recuperate from losing her other half, but otherwise seems to just enjoy it.
- Worf Had the Flu: She was drastically weakened due to her divine essence being split into two bodies, to the point that Kazuma was able to badly injure her with his home-brewed, Detonate-level dynamite.
- Your Days Are Numbered: Part of the reason why she and her followers are so desperate to recover her other half - her physical form is at risk of fading out of existence without the other half of her divine essence to stabilize her.
Duke
Duke
A fallen angel and a candidate for generalcy in the Demon King's army. Despite falling from heaven, he still despises devils and the undead.
- Accidental Proposal: Everyone thought his duel with Wiz was a Best Her to Bed Her sort of situation. He eventually reveals that he never intended to marry her, only to beat her in duel so he can take her position as general in the Demon King's army.
- Bearer of Bad News: He reveals that the Demon King is targeting Kazuma (and possibly Aqua) for defeating so many of his generals— along with the town of Axel. Wiz is not pleased with this news.
- Emergency Transformation: He turns himself into a lich after Wiz beats him within one inch of his life, making himself much more powerful— but weak to Aqua's Turn Undead. Oops.
- I Surrender, Suckers: After an enraged Wiz mops the floor with him, he accepts her offer to surrender... then takes the opportunity to turn himself into a lich like her. Not that it does him any good, as he's now vulnerable to Aqua's holy magic.
- Playing with Fire: He's a mage who specializes in fire magic, in contrast with Wiz's ice specialization.
- Wizard Duel: He challenges Wiz to one so he can take her position as General. Kazuma says that their fight is probably the single coolest thing he's seen since coming to Axel.
- Wounded Gazelle Gambit: He confesses his love for Wiz right as she's about to kill him. Then Vanir informs her that Angels, like Devils and Gods, have No Biological Sex or sexuality— then Wiz (tearfully) finishes him off with an Explosion.
Celestina AKA Serena
Celestina AKA Serena
A mysterious priestess who professes to be Kazuma's number one fan and asks to join his party, putting her at odds against Aqua. Her true identity is Celestina; a priestess in the service of Regina, the dark goddess of puppetry and vengeance. Celestina is the seventh of the Demon King's eight generals that Kazuma meets, and the highest-ranking human in his service.
- Attack Reflector: Her Curse of Vengeance returns any damage dealt to her back to her assailant. As Kazuma learns, this also applies to indirectly caused damage (such as startling her so she spills a hot drink on herself).
- Be Careful What You Wish For: When she finally makes Kazuma into her puppet, her first order is for him to "let go of his inhibitions" and "seek out vengeance". The thing is, the person who Kazuma wanted vengeance against the most at the time was Serena (for hurting Aqua). As a result, instead of a loyal puppet, he becomes The Millstone, subjects her to all his unrestrained vices, and leaves her starving, broke, and near-powerless.
- Call-Back: Wiz reveals her identity in the exact same way she revealed Hans's.
- Card-Carrying Villain: Quite literally! She states in no uncertain terms that a goddess that seeks to bind people in servitude can only be called a "dark goddess", and it's reflected on her adventurer's card, which calls her a "Dark Priest".
- Cigarette of Anxiety: She smokes partly because of addiction, and partly as a coping mechanism.
- Engineered Heroics: She presents herself as a more competent priest than Aqua by stopping some zombies with her Turn Undead after Aqua’s failed. In reality, the “zombies” were just corpses manipulated by her puppetry, so they weren’t weren’t technically undead to be susceptible to Aqua.
- Evil Cannot Comprehend Good: When she finally manages to make Kazuma her puppet, her first commandment was for him to "seek out vengeance." What Serena intended was for Kazuma to lash out against his party and the town for all the trouble they, especially Aqua, regularly put him through. She never realized that Kazuma genuinely sees his party as True Companions, and that the whole reason why he's going through all the trouble of opposing her is to punish her for making Aqua cry. This ultimately leads to her downfall, as this very first commandment lets Kazuma subject Serena to a brutal Humiliation Conga that ends with her disgraced, destitute and powerless.
- Exactly What It Says on the Tin: The powers granted to her by her patron deity Regina are this. Celestina is capable of animating an army consisting of hundreds of corpses as if they were literal marionettes, note and anyone who harms her is struck by divine vengeance, no matter how indirect the method of attack.
- Failed a Spot Check: She apparently didn't realize that Kazuma went through with resetting her level to 1 until she tried— and failed— to cast her high-level priestess magic.
- Hoist by Her Own Petard: Serena taking Kazuma as her puppet greatly backfires on her. Not only does he not follow any of her orders and instead fulfills his own (usually perverted) desires, but Kazuma's "servitude" causes Serena to lose all her other followers, destroys her reputation among the locals, and leaves her starving and broke. It gets to the point where she has to outright beg the rest of Kazuma's party to take him back and use the Anti-Puppet potion on him.
- Humiliation Conga: The entirety of Volume 15 involves Kazuma pranking her with only the most literal definitions of "harmless" in mind, and then being absolutely useless when she finally does make him her puppet. Volume 16 caps it off when she gets captured and sexually harassed by a bunch of Axis Cult fundamentalists, and Kazuma lets her know the only way to get off the hook is by converting to the Axis Cult.
- Irony: Serena turns Kazuma into her puppet with the intention of making him her loyal, obedient slave. However, Kazuma precedes to not follow any of her orders and instead decides to fulfill his own perverted desires in order to remain obedient. Eventually, Serena is forced to follow Kazuma's every whim as "compensation" for his loyalty and servitude. As a result, Kazuma ends up living a lavish life as Serena's "servant" whilst Serena becomes starved, broke, and humiliated, essentially becoming the loyal servant to her own puppet.
- Laser-Guided Karma:
- Her powers naturally invoke this, with any damage dealt to her being dealt back to her attacker even if they haven't physically attacked her.
- In a roundabout way, she could be seen as dishing this out to Aqua. Back in Volume 11, Aqua cruelly dealt a God Blow to Lucy, a follower of Regina, just as she was about to peacefully pass on. Serena turning up in Volume 15 and completely ruining Aqua's reputation as a priest could be seen as Serena getting revenge on Aqua for how she handled a fellow Regina cultist (not that she actually knew about said cultist though).
- This gets applied to Serena herself in Volume 15. After ruining Aqua's reputation, Kazuma under Serena's control as a puppet ends up ruining her own reputation and is forced through a volume-long Humiliation Conga. In the end, she's forced to beg Aqua herself for the potion to break her "control" since Kazuma actively resists her own attempts to break it.
- Her fate in Volume 16. Given her powerset involves turning people into loyal servants out of gratitude, it is only appropriate that Serena is forcibly indoctrinated as a loyal servant for the Axis Cult.
- Level Drain: Kazuma gives her a potion which resets her level to 1. Because of her Attack Reflector ability, it also resets Kazuma's level to 1.
- Logical Weakness: Despite her Attack Reflector ability, she has an unfavorable matchup against Darkness, who not only has the means and desire to inflict excruciating pain on Serena, but also enjoys recieving pain herself.
- One-Hit Kill: She has the high-level priestess spell "Death", which has the exact effect you think it would. Fortunately, Death Is Cheap for Kazuma.
- People Puppets: Her powers allow her to turn anyone who's grateful to her into her puppet, which effectively lasts until she makes them return the favor.
- Pity the Kidnapper: After Serena makes Kazuma into her puppet, he ends up not following any of her orders while using her for his own perverted desires. Kazuma then puts Serena through a volume-long Humiliation Conga so bad that by the end, she's begging the rest of Kazuma's party to take him back.
- Sinister Minister: A priestess working for the Demon King.
- Spanner in the Works: Kazuma completely believes her story about the Demon King, until Wiz (who has nothing but good intentions) shows up and reveals her identity, and Vanir (who never has good intentions) shows up and threatens to reveal everything else.
- Token Human: The only human in the Demon King's inner circle, unless you count Verdia and Wiz, who are undead.
Demon King's Daughter
Demon King's Daughter
Daughter of the Demon King.
- Informed Ability: She's allegedly the strongest General working under her father, but never directly confronts the protagonists to display so. In the finale, she loses to Iris, and then gets scared away by Megumin's manatite-fueled Explosions.
- No Name Given: She's simply known as the Demon King's daughter.
White Robe
White Robe
An Angel and former General who guards the Demon King's castle.
- Healing Factor: He's able to quickly recover from Megumin's Explosion. Rapid-fire Explosion proved too much for him.
- Informed Ability: Serena touts him up as the world's strongest mage under the enhancements he gains within the castle. His brief appearance amounts to getting one-sidedly blown up over and over by Megumin's magnetite-fueled Explosions without any semblance of a fight.
- Light Is Not Good: An angelic figure who protects the Demon King
- No Name Given: He's simply referred to by his race, outfit, or role as gatekeeper. He's blown to bits while trying to introduce himself
- Power at a Price: He has a magic circle connected to the demon realm providing him with infinite mana, regeneration, and personal barriers, but it prevents him from leaving the castle.
- Undignified Death: He's bombarded with Explosion after Explosion, stripping him naked and ultimately killing himself before he can even give his name.
- We Hardly Knew Ye: Megumin's manatite supply allows her to blow him to smithereens without a proper confrontation.
Others
Lord Alderp
Alderp Alexei Barnes
First appearing in volume 2, he's the "mayor" of Axel town, and the one antagonist that Kazuma's party can't deal with by using brute force, since he's both human, and law-abiding, at least in public.
- 0% Approval Rating: Nobody in Axel likes him. Of course, his overall despicableness shaped the opinions of the people of Axel on nobility and aristocrats in general.
- Adaptational Hairstyle Change: In the manga, he has a Bald of Evil and Beard of Evil. Meanwhile, the anime shows him with a head full of hair and only a mustache.
- And Now You Must Marry Me: Towards Darkness in Volume 7, as the latest in a long line of women used as a Lust Object by him. Kazuma, with Vanir's help, finds a way to get her out of it.
- Arc Villain: He's the villain of Volume 7 where he has an Evil Plan that nearly forces Darkness to marry him.
- Aristocrats Are Evil: Played as straight as they come, but even so, Darkness wants nothing to do with him.
- Asshole Victim: Alderp is perhaps the nastiest character in the series, so there's no sympathy for him when Vanir tricks him into completing his contract with Max, allowing the demon to not only remember that he's a high-ranking demon named Maxwell, but that Alderp also abused his short memory span to get himself infinite favors, causing the understandably vengeful demon to drag his ex-master off to hell.
- Bad Boss: To Maxwell, of a sorts. Also, he's more than willing to sell out anyone of his employees in order to save his own skin.
- Body Surf: He's apparently been jumping from body to body, killing his original host to make the swap permanent, for some time, all to gain power and influence.
- Covert Pervert: He'd like to be covert, at least. In volume 6, Kazuma's party was at his mansion in the capital city to stop a chivalrous thief. Kazuma discovers that he has a mirror specifically designed to allow him to watch his maids (and Darkness) changing.
- Dastardly Whiplash: He has a curled mustache because stereotypically evil villains like him usually have these.
- Despair Event Horizon: When Karma finally catches up to him, and he has to pay Maxwell's "price", all he can do is beg for a quick death, much to Maxwell's delight.
- Devil in Plain Sight: He makes little effort to hide how unpleasant he is, but even so, there isn't much anyone can do as there is no evidence regarding any wrong doing coming from him. Not even unpleasant rumors.
- Did You Just Scam Cthulhu?: His summoned devil, Maxwell, is incredibly powerful and can manipulate memories but has terrible memory himself. Alderp takes advantage of this to get infinite favors, though Maxwell eventually has him pay the price for his services in hell.
- Domestic Abuse: Strongly implied by Maxwell. After Maxwell breaks Alderp's arms in restraining him, Maxwell goes on to say "I won't break you like you did to all those women."
- Entitled to Have You: To Darkness/Lalatina, taken to its horrific logical extreme.
- Evil Counterpart: To Kazuma. To wit, both are very cunning and underhanded, tend to have a lot of luck on their side and their list of vices is nearly identical. The key differences are that Kazuma generally knows the difference between slapstick and abuse, and never knowingly crosses that line, he would never force himself on a woman against her will, and despite having a history of using his companions as monster bait, actually treasures them dearly. So much so that he was willing to pay a whopping 2 billion eris ransom in order to free Darkness from her Arranged Marriage. Lord Alderp not only used up women and threw them away when he got bored with them, giving them a token "divorce" payment, but when he found himself in trouble with Maxwell, tried to sacrifice his loyal staff and retainers without a second thought, purely to save himself.
- Evil Old Folks: He's elderly, and highly unpleasant.
- Fat Bastard: He's noted by Aqua to be so fat he sweats oil. Which makes a lot of sense considering that he used to Body Swap bodies once the current one started to suffer the consequences of his extremely hedonist lifestyle.
- Fate Worse than Death: Is literally dragged to hell, alive, to become Maxwell's plaything.
- Greater-Scope Villain: Besides the Demon King's army and Kazuma's own party members, he's effectively the main source of Kazuma's troubles in the first half of the novel series, being responsible for the massive debt Kazuma has to shoulder.
- Hate Sink: His utterly deplorable actions and attitude, not to mention the lengths he would go through to get his hands on his Lust Object of the season, made most fans scream for his death. He ultimately suffers an even worse fate, all through his own words and deeds.
- Humans Are the Real Monsters: A worse person than the other, nonhuman villains - with none of their Affable Evil, Laughable Evil, etc.
- Karma Houdini Warranty: Despite being an open scumbag, nobody can ever present evidence to hold him accountable for his crimes, thanks to the manipulations of his forgetful devil. However, Vanir tricks him into immediately paying for Maxwell's services and ending their contract, dragging him down to hell with his arms broken while exposing all his atrocities.
- Kangaroo Court: When Kazuma is in court after the town's prosecutor, Sena, accuses him of treason and being from the Demon King's army, Lord Alderp organizes one since his mansion was accidentally destroyed by collateral damage from the fight with the Destroyer. After Kazuma reveals he didn't willingly cause the damage and that he is not working with the Demon King (also causing the Lie Detector in the court to not go off), he sees it doesn't fit the "evidence" that he wanted, and rigs the case so that Kazuma ends up being sentenced to execution anyways.
- Like Father, Unlike Son: He's a horrible, corrupt man who tried to ruin Kazuma's life for petty reasons, but he has a son who is a gentleman and knightly individual who cares for others' happiness, asking Kazuma to make Darkness happy. This is at least partly because he adopted the finest kid he could find, probably in order to have him be the most appealing marriage prospect possible. Unfortunately for him, this completely backfires due to a combination of the bride-to-be's... unusual taste in men and his son being too decent not to respect her wishes.
- Mirror Character: Parallels between Kazuma and him have been drawn, showing that they are somewhat similar in personalities. But the main difference is that Kazuma actually has a good heart behind his scummy actions, while Alderp is a legitimately malicious and selfish person.
- Mugging the Monster: To Maxwell. Alderp does not know "Max" is a duke of hell, presuming his divine artifact summoned a "low level devil" which he thoroughly abused. Once volume 7 comes to a close, he winds up deeply regretting this. Unfortunately for him, apologizing to Maxwell only serves to make things worse for him.
- Murder Is the Best Solution: Is highly insistent on Kazuma being killed for the accidental destruction of his manor in Axel town in volume 2. What's worse is that he plans to use a divine Body Swap artifact to Kill and Replace, first his own son, and then the crown prince so he can have Darkness married to him.
- Offing the Offspring: He certainly has this in mind with Lalatina's Arranged Marriage to his own son, in order to replace him and become her husband.
- Villain: Exit, Stage Left: To the rest of the world, it seems like this: with the utter failure of his and Darkness's wedding, evidence of his corruption arose and he quickly made himself scarce. In reality, thanks to Vanir's interference, he ended the contract with the demon he was using to hide the evidence of his misdeeds, who proceeded to drag him off to Hell as "payment".
- Villainous Breakdown: When Aqua seals the Body Surf artifact, Alderp throws a fit and beats up his summoned devil. Later, he has an even bigger breakdown when said devil drags him to hell.
Maxwell "Max" (SPOILERS)
Maxwell "Max"
Alderp's devil, summoned by a divine artifact that compels a random "monster" to serve the one who uses it. Although Kazuma's party has no direct contact with him, since he's under Alderp's control, he is responsible for a great deal of the heroic party's suffering, especially Lalatina's.- Beware the Silly Ones: On the surface, he appears to be a complete harmless idiot that Alderp abuses on a regular basis. In reality, he's an Arch-Devil, one of the seven Dukes of Hell and doesn't share Vanir's policy of not harming humans.
- Body Horror: He's missing the back half of his head.
- Deal with the Devil: Quite literally. Alderp abuses it for all it's worth through Easy Amnesia.
- The Dog Bites Back: At the end of Volume 7, after years of being abused and exploited by Alderp, Maxwell is eager to feed on Alderp's despair and says he will keep Alderp alive for as long as possible to torture him until he gets tired of him.
- The Dragon: To Alderp, though not entirely by choice.
- Emotion Eater: Like Vanir, he feeds on negative emotions. Despair being his favorite.
- Foreshadowing: Volume 3 alludes to his existence in the courtroom scene, where Aqua senses the influence of an evil power affecting things.
- Forgetful Jones: He can alter people's memories, but has an absolutely horrible memory of his own. Someone leaving the room and coming back a few minutes later is often enough for him to forget who that person is.
- Instant Allegiance Artifact: Is victim to one under Alderp for quite some time. Volume 7 changes all that.
- Lacerating Love Language: When he says he likes Alderp, he seems to mean it. Specially the sound of his screams.
- Meaningful Name: Maxwell's Demon
is a thought experiment about a setup that violates the second law of thermodynamics in theory, but which fails in practice because the titular demon cannot retain information indefinitely, here referenced by Max's memory problems. - Mugging the Monster: Is on the receiving end of this for quite some time at Alderp's hands, and feet.
- Psychopathic Manchild: Alderp notes at the end of volume 7 that he's smiling like a young child getting a new toy.
- Red Baron: The Twister of Truth.
- Sadist: To Alderp's horror, Maxwell turns him into his new toy that he'll break over and over again out of love for Alderp's despair.
- The Stoic: During all the time in Alderp's service, he shows absolutely no emotion. When the contract is ended, he smiles at the thought of collecting his payment.
- Verbal Tic: He's almost constantly yelling "Yee!"
- A Wolf in Sheep's Clothing: He seems harmless when he's stuck as Alderp's servant, but when it's finally time to claim his price from Alderp, he reveals his true sadistic nature as he gleefully breaks Alderp's bones.
Lugkraft (SPOILERS)
Lugkraft
The prime minister of Elroad, who pressured Prince Revi into eliminating defense funding for Belzerg.- Arc Villain: He's the villain of Volume 10.
- Becoming the Mask: He was so immersed in his cover job as the prime minister to the point of forgetting his mission as a spy for decades.
- The Blank: His true appearance is a pitch black humanoid silhouette with no facial features.
- Ditzy Genius: He's fairly competent in politics, but he also suffers from tunnel vision causing him to work far harder for the country than is necessary for his infiltration mission.
- Even Evil Has Standards: When Lugkraft became a minister of domestic affairs, he was appalled by Elroad's spending and gambling culture, which was putting them into extreme amounts of debt.
- Failed a Spot Check: As an experienced politician in charge of Elroad's foreign affairs, as well as the head of the Demon King Army's intelligence division, he ought to have been able to figure out Kazuma's real identity, or at least have been able to deduce that he wasn't really Iris's brother by blood. This ends up giving him away when he uses his powers to impersonate Kazuma and ultimately gets him killed by Iris.
- Human Disguise: He has the ability to change his appearance, which he uses to pass himself off as a human.
- Humanshifting: As a Doppelgänger, Lugkraft can make his appearance identical to anyone.
- Internal Reformist: He managed to reverse Elroad's self-destructive financial situation despite being on the Demon King's side.
- Jerkass: He gloats about how he's going to use Kazuma's appearance to ambush his companions and kill Iris while taking pleasure in the latter's frustration, though this is mostly in response to how Kazuma nearly put an Elroad casino out of business.
- Mistaken Identity: He takes Kazuma and Iris's relationship at face-value, and assumes that Kazuma is Iris's older brother Jatis and the Crown Prince of Belzerg. He even rationalizes that "Jatis's" dark hair and eyes is due to him being a genetic throwback to the legendary (sent Japanese) heroes of old. Naturally, hilarity ensues.
- Mole in Charge: He's actually the leader of the Demon King's intelligence division.
- Motive Rant: After tying and gagging Kazuma and Darkness, he goes on a really long rant about his efforts to infiltrate Elroad's government for the Demon King.
- Obstructive Bureaucrat: He's the one behind the cuts to Elroad's military funding to Belzerg and tries to justify it by claiming the Demon King will recognize their neutrality and leave them alone.
- Shapeshifting Seducer: He takes Megumin's form and appears to seduce Kazuma, just to trick and capture him. He tries taking Kazuma's form to seduce Darkness and Iris as well, but they see right through his disguise because the real Kazuma would never act chivalrous.
- Too Dumb to Live: He attempts to kill Iris, even though she's stronger than the rest of Kazuma's party combined, resulting in his rather anticlimatic death. This is long after she proves herself to be a One-Woman Army capable of slaying a dragon with barely any effort.
- Treacherous Advisor: He's the reason why Prince Revi acts like such a jerk to Iris and Kazuma's party, which he hopes will destroy relations between Elroad and Belzerg.
- Undying Loyalty: He takes great offense to any insults to the Demon King, even when he's in his prime minister guise.
- Walking Spoiler: As a Mole in Charge and a shapeshifter, he's not easy to talk about without spoilers.
Zeeleschilt
Zeeleschilt
A lord of a small village, and a high-ranking devil whose fingernail is needed to cure Sylphina's disease. He also inexplicably wears a penguin costume.
- Affably Evil: Much like Vanir, he doesn't descend into violence until he's provoked, and has quite amicable negotiations with Kazuma and Darkness.
- Anti-Villain: He was perfectly willing to deal with Kazuma and Darkness, and he only didn't give them his fingernail because they couldn't hold their end of the bargain. He only attacked Darkness after they snuck into his castle to steal it. Kazuma also mentions that the people living under him were also content with his administration, so he never really deserved what he got.
- Butt-Monkey: After he moves to Axel, he's a constant target of Aqua randomly exorcising him.
- Combat Tentacles: He can sprout a tentacle from anywhere he's cut.
- Embarrassing Animal Suit: Subverted. Kazuma's really the only one put off by his penguin suit (which he believes is a mascot costume from Earth). Zereschrute points out some of it's benefits, like being waterproof and heat proof. It also conveniently hides his true form.
- Emotion Eater: He's a devil, and subsists on the negative emotions humans produce, preferring emotions like fear and pain. Unfortunately for him, instead of torturing Darkness, he ends up becoming the (probably) first character to indulge her masochist fantasies if Kazuma's subsequent reproachful remarks to her are to be trusted.
- Eye of Newt: His fingernail is needed to brew the potion that cures Sylphina's illness.
- Pet the Dog: As it turns out, he's on fairly good terms with Princess Iris, whom he apparently met when she was a child.
- Pragmatic Villainy: He refrains from doing Devil-ish things to his subjects, knowing that rousing them may cause the capital to investigate him. This ends up saving his bacon when Eris beat him to an inch of his life instead of killing him, the Knight Templar of an anti-Devil goddess only sparing him because she realized that no human died at his hands.
- Riches to Rags: After the events of of Volume 12, Eris attacks his castle every day, forcing him to abandon it and his aristocratic position to work with Vanir and Wiz when he nearly runs out of Video-Game Lives.
- Take Our Word for It: He did something to Darkness that left her flustered and Kazuma taken aback, but the narration refuses to specify what happened.
Arnes
Arnes
A demon in service to the Demon King, and a faithful servant to Demon General Wolbach.
- Adaptational Modesty: In the anime, she wears a leotard that's notably less revealing compared to her outfit from the light novel and manga, which showed off her cleavage and midriff.
- Face Death with Dignity: She challenges Megumin's Explosion with her own Cursed Lightning spell, and when it becomes clear to her that she can't win the resulting Beam-O-War, she merely looks towards Chomusuke (the vessel of her mistress Wolbach) and apologises for her failures, before going out with a smile.
- Facial Markings: She's a demon with triangular marks on her cheeks.
- Horned Humanoid: She has goat-like horns sprouting from the sides of her head.
- Hot as Hell: She's a demon who looks like a beautiful and voluptuous woman in a very revealing attire.
- Near-Villain Victory: She comes very close to stealing Chomusuke away and obliterating Megumin and Yunyun (who can't attack without hurting Chomusuke). Unfortunately, she is undone by the Divine Intervention of the Goddess Aqua - namely, the arrival of Kazuma and Aqua into the world, which created a pillar of divine light. This distraction gives Chomusuke a moment to bite her and make her drop him, giving Megumin free range to unleash Explosion.
- Noble Demon: She doesn't go out of her way to pick fights if she doesn't have to, and as with most demons of the setting, she always honors any bargains she makes with others. She even offers 300,000 eris for Chomusuke's return, with no strings attached. Unfortunately, Megumin is more attached to her familiar than she lets on, and is very willing to keep the money when Arnes is driven off by her Weirdness Magnet effect. This quickly makes the matter personal for Arnes.
- Pointy Ears: She has pointed ears similar to an elf.
- Polite Villains, Rude Heroes: Arnes is respectful in her interactions, and to her annoyance, Megumin never returns her manners, taking the money Arnes offers for Chomsuke and setting Arnes to take the fall for poisoning Arcanletia's water. In the anime, Arnes lampshades this trope when it comes to interactions with humans and demons, saying it is always the humans who break their word.
- Starter Villain: Serves as this for Megumin, being the first major demon she ever defeats.
- Supernatural Gold Eyes: She's a demon with yellow eyes.
- Trauma Button: Thanks to becoming a Weirdness Magnet for the "worthless men" of the world after buying Hyoizaburo's cursed "magic" bracelet, anything involving promises, even she herself saying the word randomly, will send her into a violent trauma fit over all the times she was screwed over by broken promises, and Megumin taking her money without handing over Chomusuke, thus being another "promise-breaker", makes Arnes decide It's Personal.
- Weirdness Magnet: Due to a magic wristband (or perhaps "cursed" is the better word) she purchased from Megumin's parents, she becomes a magnet for the lechers and freaks of the world to come and harass her, which does result in her getting chased out of Arcanretia by most of the Axis cult.
- Winged Humanoid: There are bat-like wings protruding from her back, but she mostly otherwise looks human.
Hoost
Hoost
Voiced by: Itaru Yamamoto (Japanese) Foreign VAs
The primary antagonist of the Explosions! spin-off prequel. A powerful Greater Demon (formerly) contracted to Wolbach as her top enforcer. His attempts to recover Wolbach's sealed other-half drove much of the plot.
- Affably Evil: When he isn't mad, Hoost can be quite well mannered. This is best seen with his interaction with Komekko, but even when he meets Megumin he offers her a sincere deal rather than try to fight.
- The Brute: Subverted. He definitely has the appearance and abilities down pat, but is much more intelligent and even-tempered than he lets on.
- Doomed by Canon: Is already dead by the time Megumin joins Kazuma's party, and is long gone by the time they confront his former master, Wolbach.
- Face Death with Dignity: When staring down Megumin's Explosion spell, he simply chuckled to himself and mused that he'd finally have some time off in hell.
- Genre Savvy: When facing the massive raid sent from Axel to deal with him, he doesn't bother with the typical introductions or grand-standing. Instead he ambushes the raid and blindsides Kyouya, nearly killing him in the process.
- Good Wings, Evil Wings: Sported a pair of massive bat-like wings that allowed him to fly at high speeds.
- Horned Humanoid: Sports four horns in total - one large pair sprouting from the top of his head, and a slightly smaller, mandible-like pair growing from his cheekbones.
- Lightning Bruiser: Incredibly strong, ridiculously durable, and remarkably fast for his large size. Oh, and he can cast Advanced magic.
- Muscles Are Meaningful: Extremely muscular, which is highlighted by the fact that he doesn't actually wear clothes or armor of any kind. He's also one of the physically strongest and most durable enemies in the series.
- Noble Demon: Despite being a Demon General, Hoost isn't a particularly malevolent guy, he doesn't like to fight people if he doesn't need too and is actually very sweet to Komekko. Additonally he is completely devoted to Wolbach despite not technically working for her, showing that he is loyal as well.
- Odd Friendship: He forms an unexpected friendship with the young Crimson Demon, Komekko. He likes her so much that he promises to become her Familiar if she ever manages to summon him.
- One-Man Army: Single-handedly took on an expeditionary raid consisting of nearly every adventurer in Axel. The only reason none of the adventures died is because they were smart enough to form a vanguard of their tankiest warriors and knew to run the hell away as soon as Kyouya went down.
- Pet the Dog: Has plenty of moments with Komekko during the interludes of Volume 1. When they part ways he even gives her an Affectionate Gesture to the Head, and she notes to herself that he was the first friend she ever made.
- The Promise: He tells Komekko that he'd become her familiar should his contract with Wolbach ever expire. Plot-wise it also explains why Wolbach couldn't simply revive him by making a new contract with him.
- Playing with Fire: Is a master of Advanced-class magic, but favors the Inferno spell.
- Pragmatic Villainy: Of the "discretion is the better part of valor" variety - despite his immense power, he avoids unnecessary violence in order to avoid drawing attention to himself. Unlike Sylvia and his coworker Arnes, he went out of his way to avoid picking a fight with the Crimson Demon Clan, knowing that it would be a waste of time and energy to confront them directly.
- Resurrective Immortality: When he runs out of Video-Game Lives he simply returns to hell. He can be brought back to the living world if or when a summoner makes another contract with him.
- Super-Toughness: Somehow managed to survive hits from both Gram and Aqua's God Blow, both of which are known for their One-Hit Kill properties. According to Hoost, he probably would have been able to survive Megumin's Explosion too if he had time to recover his lost health and stamina.
- Trauma Conga Line: Taken to Rasputinian Death levels. First he was attacked by a 50-man raid and had one of his wings cut off by Kyouya. Then he was assaulted by Darkness and Chris. Then Aqua slapped him in the face with a God Blow when he tried to scout the town. And finally he spent hours having his stamina worn down by Yunyun going full Geralt of Rivia on his ass with TEN MILLION Eris worth of scrolls, potions, traps, and other magic consumables before being finished off by Megumin's Explosion spell.
