BEEL'S FACTIONBaby Beel and the demons who are loyal to him.
Kaiser de Emperana Beelzebub IV
- Voiced by: Wataru Takagi
- Abhorrent Admirer: Furuichi does not appreciate his affection, or obsession. Alaindelon talks about Furuichi to his daughter using the honorific "sama" for whatever reason. The anime takes this trope and runs full steam with it.
- Ambiguously Bi: No surprise here. He's noted to be just as creepy around Furuichi as Furuichi is around girls, yet also has a daughter.
- Bag of Holding: His purpose. Has also led to a lot of "inside jokes" with Furuichi.
- Disney Death: Most DEFINITELY parodied in the Demon World Arc.
- Macho Camp: Definitely no surprise here. Turned Up to Eleven in the anime if you can believe it.
- No Celebrities Were Harmed: He's based off Freddie Mercury and named after French actor Alain Delon.
- Stalker with a Crush: To Furuichi.
- Stealth Hi/Bye: Being a teleporter, it comes with the territory. He even provides the current trope picture.
- Teleporters and Transporters: A living teleporter.
- The Ugly Guy's Hot Daughter: His daughter Angelica. Like wow.
Dr Forkas Rachmaninnor
- Voiced by: Akio Kato
- Awesome Mccoolname: Have you seen it?
- Dope Slap: When reminding his assistant that she's not the real doctor.
- The Faceless: Sort of. When he first appears in the human world he uses a muumuu body, which is basically a slime with two eyes, arms and a hat.
- In a later chapter set in the Demon World he appears to have a humanoid body.
- Nice Hat: The only item of clothing he wears when in his puppet body.
- Playing Both Sides: Claims to be on the side of the sick, and heals both Hilda and the demons that work for Behemoth's group after the attack.
- The Unpronounceable: Once again, this guy's name.
- Voiced by: Kaori Fukuhara
- Actually, That's My Assistant: Was thought to be Beel's doctor until the REAL doctor showed up.
- Boom, Headshot!: The way she gets Oga to enter his Mental World.
- Bratty Half-Pint: Most definitely this.
- Head Pet: Has a little ghost who tends to just sit on her head and look cute.
- Magic Skirt: Justified in that it's a business skirt, so it's rather tight and less likely to flap around.
- Not What It Looks Like: Gets into quite a bit of these situations with Furuichi. His reputation goes further down the drain with each one.
- Odd Friendship: With Furuichi. She noticeably relies on him more than anyone else despite her complaints. Some characters think it's because there's something more.
- Precocious Crush: She gets a crush on Furuichi, which her mother notices and thinks is cute... until he begins openly ogling her chest to see how big Lamia might get in the future.
- She Is All Grown Up: Not quite there yet, but she's definitely growing up as she pointed out to Furuichi in a side story.
- Interspecies Friendship: She is a demon whereas Furuichi is a human.
- Token Mini-Moe: Though considering she's a demon, it's unclear if she's really as young as she looks.
- Tsundere: Furuichi certainly seems to think so and her actions and reactions when she's around him really don't help her case.
- You Gotta Have Blue Hair: Her hair is pink. Sort of justified, considering that she's a demon.
EN'S FACTIONLord En and the demons who are loyal to him. At the time when Oga and company are attending Saint Ishiyama, the Pillar Squad rebuilt the original delinquent school and took it over under the name of Akuma Academy. Their plan being to use Akuma Academy as a means of operations to help En become the Demon King and as the destroyer of the world.The main cast however, sees this as a declaration of war from seeing their school taken over. A viewpoint that was partially sparked by Furuichi who had united everyone under tales of a mysterious Akuma Academy without knowing it actually existed. A rivalry between the delinquents and Akuma Academy ensues...
Beel's older brother, he is sent to destroy Earth due to Beel taking too long, but decides video games are more important than his duties. He has three demon maids of his own: Yolda, Satura, and Isabella.
- Abhorrent Admirer: To Lamia.
- The Battle Didn't Count: Beat En at his own game? He will just have you play another one and another and another...
- Big Ol' Eyebrows: The bushiest yet!
- Disco Dan: The most advanced consoles he knows are the SNES and Sega Genesis, at least until he goes to the human world.
- Informed Ability: For someone who puts video games before world destruction, he sure relies on his wet nurses a lot. Lampshaded by Furuichi and Lamia several times.
- Meaningful Name: The kanji for (part of?) his name, 焔,can literally translate as "Fire." "En" also may bring to mind Enma-ou, the judge and ruler of hell in Japanese mythology.
- Playing with Fire: He creates seas of fire when he cries, enough to destroy 30 towns in Hell and on Earth, possibly everything in a 9 mile radius.
- Spell My Name with an "S": His name in Japanese is "Enou," but the scanlations translate it as "Lord En." Only time and context will tell which is correct...
- Chapter 123 confirms it as Lord En. A teacher in Akuma Academy reads it as Enou and faces the wrath of the Pillar Squad for his troubles.
- However, some foreign official translations name him Enou, and in the situation referenced above, the teacher calls him Enou-kun instead Enou-sama.
- Chapter 123 confirms it as Lord En. A teacher in Akuma Academy reads it as Enou and faces the wrath of the Pillar Squad for his troubles.
- Spoiled Brat/Royal Brat: To say that he's been pampered and spoiled through his entire life would be a gross understatement.
- You Gotta Have Blue Hair: Green, matching Baby Beel's and their father, the Great Demon King.
- Voiced by: Tomomichi Nishimura
- Badass Grandpa: Capable of manhandling both Oga and Tojo in the Hero show. Not to mention when he possessed Furuichi and lent him only a fraction of his power, Furuichi become strong enough to fight toe-to-toe against Oga who was using Super Milk Time.
- Beard of Evil
- Bigger Bad: Behemoth is not really in charge of his division anymore anymore, having handed control over to his son, but he's still the one who orchestrated the division's attack on Oga as well as Hilda's kidnapping, making him this for the Akuma Academy arc.
- Dirty Old Man: Subverted with his plans for Hilda. He asks her for her tits, but he really meant he just wanted her to be En's new nurse maid.
- Then we have the outfit he materialized on Aoi during the Hero Show. That really wasn't necessary.
- Flash Step: He's so fast, even master martial artists and a powerful spellmaster can't follow him.
- If I Wanted You Dead...: He delivers a silent one to Furuichi and Lamia during the battle of Akuma Academy by looking right at Furuichi (who was observing the situation through binoculars from the protagonists' faraway HQ) and winking.
- Improbable Weapon User: Beat two of the Six Knights with his shoes tied together by the strings
- Knight of Cerebus: With a couple exceptions (such as when he magicked Aoi into a dominatrix outfit), Behemoth's presence always means the story is about to get a lot darker. Not only did he usher in En's army, he kidnapped Hilda, had Yolda brutalized for her powers, and had Hilda's memories erased in hopes of turning her into En's new maid.
- Nerves of Steel: He has only ever lost his cool once, when Oga cuffed En upside the head.
- Retired Monster: Specifically refuses to fight Oga and the others since he knows if he gets involved, so will Oga's teachers.
- Undying Loyalty: To En.
- Villainous Rescue: Sort of helps bring the Hero show to an end by 'pretending' to be a Bigger Bad to Oga's pretend role Big Bad when he and Tojo stop pretending to fight each other and go all out scaring some of the children watching.
Maid TrioA trio of demons who serve as En's personal attendants.
- Voiced by: Minako Kotobuki
- Absolute Cleavage: Her dress isn't laced up tight enough.
- Aww, Look! They Really Do Love Each Other: She does care for her sister Hilda, such as asking En what's the cure for her amnesia.
- Broom Stick Quarterstaff: A mop, and it's her Weapon of Choice.
- Dark Action Girl: Although she's pretty weak compared to Hilda.
- Femme Fatale: Very flirtatious and likes touching and kissing her opponents.
- The Gadfly: After the Akuma Arc, she can be a bit of a troll, and obviously enjoyed spreading chaos around St. Ishiyama by telling everyone (especially Aoi) how Hilda could get her memories back.
- Identical Strangers: She looks very similar to Hilda, much to her annoyance. It's actually Strong Family Resemblance.
- Meido: Her outfit resembles this more than Hilda's.
- Shameless Fanservice Girl: She changed right in front of Furuichi keeping everything worth seeing just hidden from view, all so she could troll him.
- Teleporters and Transporters: She's a teleporter demon, like Alaindelon.
- Voiced by: Yurie Kobori
- Bare Your Midriff: Her maid outfit literally consists of a mini skirt and a bikini top.
- Beauty, Brains and Brawn: Is the Beauty, with Isabella being the Brains and Yolda being the Brawn.
- Chromatic Arrangement: En's maid trio follows the primary color palette. Satura is red.
- Curtains Match the Window: Had red eyes and red hair.
- Evil Redhead: During the En arc.
- The Gunslinger: Uses a pair of pistols in combat.
- Ninja Maid: Her job is to safeguard and look after En.
- Red Eyes, Take Warning: Her eyes fit this trope when she's actively opposing Oga and company.
- StripperIffic: Her maid outfit is by far the most revealing of the three.
- Winged Humanoid: Has a pair of bat wings in her first appearance. Though this is the only time she's shown with them.
- Zettai Ryouiki: Grade A in her maid outfit.
Voiced by: MinaThe strategist of En's maid trio.
- Nerd Glasses: Wears glasses, and happens to be the most intellectual of the maids.
- Ninja Maid: Similar to En's other two maids, only she's a lot less reserved.
- Non Action Gal: Compared to the other two maids, she mostly leaves the fighting to them.
- The Stoic: Compared to the other two maids, she hardly gets emotional.
- The Strategist: Comes up with the plans for En, and the other maids, to follow.
- You Gotta Have Blue Hair: Self explanatory. Though, she is a demon, so it's kinda justified.
Behemoth's 34 Pillar DivisionA demon military division consisting of 394 members serving directly under En. The "34" in the division's name refers to its most powerful warriors: the 10 mighty Pillar Barons (alternately translated as Pillar Heads) and the 24 less powerful but still formidable Pillar Generals (alternately translated as Pillars). The division's goal is to assassinate Oga and bring Beel home, thereby allowing En to destroy the human world.
Tropes applying to the group as a whole
- Action Girl: Barons Vritra and Ananta, as well as Generals Agiel, Fabas, Paimel, Tiriel, Yshiel, and Lunana.
- All Your Base Are Belong to Us: Their headquarters on Earth was the repaired Ishiyama High... and all of the students other than the main cast were brainwashed into being their slaves.
- Asskicking Equals Authority: The chain of command goes from Leader (Behemoth/Jabberwock) to Pillar Baron to Pillar General to the rest. Needless to say, the Leader is the most powerful, followed by the Barons and then by the Generals.
- Badass Longcoat: Standard uniform for the 34 Pillars.
- Badass in a Nice Suit: Though many prefer custom uniforms, the standard uniform for all serving consists of a white double-breasted suit.
- Custom Uniform of Sexy: With the sole exceptions of Laymia and Vritra, all of the female pillars have custom uniforms that (with the exception of Elim's uniform) show off substantially more skin than the standard uniform.
- Elites Are More Glamorous: Though they're the villains, not the heroes, the only ones that are relevant to the story, or even given names, are the officers.
- End of the World as We Know It: Their goal.
- Eviler Than Thou: Behemoth kicks out En's three maids for not keeping him focused on destroying humanity. But they keep Yolda to transfer their soldiers from the Demon World, promising her that she can stay with En. Naturally they lied.
- During the "Return to Ishiyama" arc even they recognize the danger Fuji and Satan represent and resolves to aid Oga by making a contract with Furuichi. Unfortunately, most of them are turned to stone before they can make a difference.
- Facial Markings: Each of the Pillar Generals has a number exclusive to them which is tattooed somewhere on their body, and many of them have their tattoos on their faces.
- Little Bit Beastly: The fish-like 'ears' that virtually all of the Behemoth members have. Only exception to this is Agiel, who has human-like ears.
- The ears seem to be symbolic * that the group originated under a Duke Bahamut, one of the great Demon Leaders and presumably a Dragon before Beelzebub subjugated him.
- Mook: Any member that isn't the Leader, a Baron, or a General is this.
- Murder Is the Best Solution: Whenever a human-related problem comes up, they immediately jump to murder it, not even trying to incapacitate. This likely stems from the fact that as far as they're concerned, all of the humans will die soon anyway.
- My Master, Right or Wrong: Morality doesn't even factor into it with these guys. With the exception of Jabberwock, and Laymia all of them view the wishes of their master En as "good" and everything else as "bad".
- Only Known by Their Nickname: Maybe. Odonel says that each of the Pillar Barons "is given the name of a well-known dragon," but it's unclear if they are given these names as nicknames once they reach the rank of Baron, if these are their actual names, or if they change their names once they become Barons.
- Summon Magic: Furuichi uses them to great effect when he gets the hang of summoning them.
- Theme Naming: High ranking officers* are named after dragons (Behemoth, Jabberwock, Basilisk, Naga, Salamander, Lindworm, Kirin, Yata, Quetzalcoatl, Yinglong, Fafnir, Ananta, Vritra) while the Pillar Generals are named for the Alphabet of Angels (Agiel, Belah, Chemor, Din, Elim, Fabas, Graphiel, Hecadoth, Kne, Labed, Nebak, Odonel, Paimel, Schethalim, Tiriel, Vabam, Wasboga, Xobla, Yshiel, Zela).
- Token Mini-Moe: Pillar General Elim.
- Undying Loyalty: To Prince En.
- Villains Out Shopping: After Akuma Academy's destruction, groups of them can be seen hanging out in random places such as fishing or going to amusement parks.
- The Worf Effect: Since the end of the Akuma Academy arc, they haven't had the best showings outside of contracts with Furuichi.
Behemoth's son and the acting leader of the 34 Pillar Division. He is an arrogant and cruel demon who doesn't care much for anything that doesn't involve hurting people.
- Arrogant Kung-Fu Guy: Jabberwock is ridiculously arrogant and dismissive of almost any enemy he is faced with.
- Asskicking Equals Authority: Despite having been kicked out in the past, Jabberwock was called in to lead the 34 Pillar Division because, aside from Behemoth, there was nobody in the division who could stand a chance against him.
- Ax-Crazy: To say that this guy is nuts and a danger to society would be an understatement.
- The Beastmaster: He summons a massive "Grand Bahamut" dragon called Sodom to kidnap Hilda.
- Big Bad: As the leader of the Pillar Division, he is this for the Akuma Academy Arc.
- Blood Knight: This guy enjoys fights as much as Oga and Tojo.
- Childhood Friends: With Laymia. They apparently played together often when they were children, but sometime before the series began, their relationship seems to have soured when Jabberwock's excessive brutallity and vicious temper got him kicked out of the Pillar Division. He, however, still greets her like an old friend, though he does tell her that things aren't the way they once were and he's now her superior.
- Curtains Match the Window: His eyes are the exact same colour as his hair.
- The Dreaded: Hilda is visibly terrified when she learns this guy's taken over as leader of the 34 Pillar Division.
- Fiery Red Head: You wouldn't think it from the way he presents himself, but his recklessness is what got him his epithet and when he finds a good fight, he drops all semblance of calm.
- Good Scars, Evil Scars: He has several facial scars, the most prominent of which runs in a diagonal between his eyes and over his left cheek.
- Kick the Dog: As if we needed any more proof that this guy's a colossal douche, he tries to kill an incapacitated Hilda with a powerful blast of magic just so that Oga would focus on their fight.
- Large and in Charge: Standing at a towering height of 9'2", Jabberwock is one of the largest characters in the series, if not the largest.
- Made of Iron: He takes two powerful attacks from Tojo and Oga and gets up like they were nothing.
- Perpetual Frowner: Jabberwock's face has two expressions: bored, condescending frown, and Slasher Smile.
- Red Baron: He's known as "Crazy Dragon," on account of his ridiculous power and reckless Blood Knight tendencies.
- Red Eyes, Take Warning: The fact that he has red eyes is just one of many clues that this man is not the one with whom to fuck.
- Slasher Smile: Whenever he gets a good fight, he's got a truly terrifying smile plastered all over his face.
- Undying Loyalty: Averted. Not only is he the only one in the division not loyal to En, he seems to despise the prince because he's a spoiled brat.
- Worthy Opponent: Subverted: He compliments Oga and Tojo during their battle, but that just makes him want to kill them more.
- It's possibly played more straight with the respectful way he speaks to Saotome.
Laymia is a Pillar Baron and was the acting leader of the 34 Pillar Division before Jabberwock's return. She is calm and collected, and surprisingly reasonable. She's a childhood friend of Jabberwock's and Lamia's mother.
- Action Mom: Implied. She's a Pillar Baron, which means she's one of the ten most powerful members of the 34 Pillar Division besides Jabberwock and Behemoth, but we never get to see her fight.
- Affably Evil: She is always polite and respectful to such a degree that she doesn't come off as being'evil' at all.
- Asskicking Equals Authority: Maybe. This is the way that the 34 Pillar Division does things, but given how she was only a placeholder before Jabberwock returned to take command, she may have only been selected as leader thanks to her administrative abilities.
- Badass in a Nice Suit: She wears a snazzy double-breasted suit underneath her pillar coat.
- Childhood Friends: With Jabberwock. They apparently played together often as children, but sometime before the series began, their relationship turned sour when Jabberwock's tendency towards excessive violence got him kicked out of the 34 Pillar Division. The next time she sees him, upon his return, she reacts with open suspicion and hostility.
- Evil Genius: It seems to be her role in the division. She serves as a direct and trusted advisor to Behemoth and is responsible for overseeing the day-to-running of the division.
- Surrounded by Idiots: Her reaction (third panel) to Salamander and Vritra getting into an argument about the word the word "Chopag/Gchipac".
- Informed Ability: As a Pillar Baron, she's one of the ten most powerful members of the division, and given how she was placed in charge of the Division after Behemoth's retirement, she may be the most powerful one of them all. However, we never actually see her in a fight, so we have no idea if she can back this up or not.
- Lady of War: Implied. She carries herself with grace and elegance, and her weapon is a slender rapier, but we never actually get to see her fight.
- My God, What Have I Done?: She gives a minor, subdued version of this after she gives En a What the Hell, Hero? moment. As soon as she finished talking, she realized that she'd just upset someone whose tears release a sea of fire, and she understandably has a small Oh, Crap! moment.Laymia: Oops.
- Number Two: She is this to Behemoth, as she ran the division in his absence once he retired
- Only Sane Man: She seems to be the only member of the the division who isn't a hopeless Blood Knight or majorly quirky in some other way.
- Pet the Dog: She's an extremely high-ranking member of the 34 Pillar Division and one of the architects of the plot to assassinate Oga and rid Beel of his contractor, but she also asks Dr. Forkas Rachmaninnor to look out for her daughter.
- Precision F-Strike/Sophisticated as Hell: She is normally very mild mannered, but she does swear once when relaying Behemoth's orders verbatim."I will now convey to you the words of our division leader, Behemoth. 'Don't fucking come back without accomplishing anything. Finish what you started'."
- Reasonable Authority Figure: She's quite reasonable and will forgive her subordinates for breaching protocol or acting independently as long as it was worth it and helped the division, and even when it is not, she is willing to hand out second chances so that her men may redeem themselves.
- The Reliable One: She's calm and can be counted on to see to the day-to-day running of the division.
- Rose-Haired Sweetie: Subverted: She has the pink hair, but she's always calm and collected.
- Royal Rapier: Though we don't see her using it, she wears one at her hip. She draws it against Fuji and Satan during the final encounter.
- The Smurfette Principle: As Vritra and Ananta were essentially Adapted Out of the Anime, she's pretty much the only female Pillar Baron.
- Statuesque Stunner: Standing at 6'11", she's taller than most men, and still quite beautiful.
- Although now, she seems to have shrunken down to a more normal height for women as she appears just under Furuichi's height.
- The Stoic: She emotes all of twice, and in both instances, the emotions she displays are subdued: Once, when she is shocked when Jabberwock returns and shows him open hostility, and again, after she calls out En's selfish behaviour, she has a minor Oh, Crap!/My God, What Have I Done? when she realizes that everything's going to start burning real quick. She then gets a major Oh, Crap! when Oga whacks En upside the head.
- Strong Family Resemblance: Lamia got her pink hair and green eyes from her mother.
- With All Due Respect: Having had enough of En insulting her comrades, Laymia calmly tells him that the fact that all of them were defeated and in no condition to fight was his fault.
- Yamato Nadeshiko: She has shades of this, being calm, collected, and mature and giving off a quiet, calm grace underneath which is uncompromising steel. She has quiet, undisputed authority over the the other Pillar Barons, and though she is unquestioningly loyal and subservient to Behemoth and Prince En, she is also the only person in the series to call En out to his face for his selfishness (the Ishiyama students who insulted him without having a clue who he was don't count). However, given how she's introduced as the acting commander of the division, she doesn't really fit the wifely side of the trope, and despite being decidedly feminine, she still dresses in a man's double-breasted suit.
Pillar Baron Basilisk is a large hulking demon who is not nearly as evil as looks. He can always be seen smoking a cigar.
- Affably Evil: He's genuinely honourable and respectful to enemies.
- An Ax To Grind: His weapon of choice is a massive axe.
- Badass Beard/Beard of Evil: For a given definition of Evil.
- Berserk Button: Calling En "Enou"* is a big Berserk Button he shares with Salamander and Yata.
- The Big Guy: He's one of the biggest members of the division.
- Cigar Chomper: He always has one.
- Even Evil Has Standards: He doesn't really like the men that Jabberwock brought with him when he took command of the division as they are far less honourable than he is.
- Face of a Thug: What with his scars and massive stature, one could be forgiven for assuming he was one of the more brutish members of the division, but he's actually one of the nicer and more honourable demons we've seen.
- Good Scars, Evil Scars: He's got a pair of scars over his right eye.
- Meaningful Name: Though he can't turn people to stone like the mythical creature can, he can paralyse them with his eyes.
- Vitriolic Best Buds: With Agiel. During their first scene together, they trade insults and death threats, but after the Akuma Academy arc, the two of them (plus Quetzalcoatl and Vabam) can be seen fishing together.
Salamander is an easygoing Pillar Baron. While physically unimposing, he specializes in powerful magics that target the mind.
- Adaptational Dye Job: His hair, as can be seen on the cover of Volume 15, is white in the manga, yet in the anime, it is orange.
- Affably Evil/Faux Affably Evil: He switches between the two, depending on whether or not he's talking to a comrade or an enemy.
- Benevolent Boss: While Basilisk stated that Graphel and Hecadoth, who had acted without permission, should be punished, and Yata went one step further and said they should be executed, Salamander was all for letting them off with a slap on the wrist.
- Berserk Button; Calling En "Enou"* is a big Berserk Button he shares with Basilisk and Yata.
- Bishōnen: Though sometimes he can be a bit too creepy to pull it off, he's generally quite pretty.
- Dissonant Serenity: The man is always smiling cheerfully, no matter what he's doing.
- Flat "What.": When Oga and Tojo simultaneously punch him. He'd previously used a sort of hypnosis spell on them, but Lamia warned them about it before hand, protecting them from its effects.
- Idiot Hair
- Long-Haired Pretty Boy: His hair reaches down to his waist.
- Meaningful Name: The Salamander is an elemental spirit described by the alchemist Paracelsus as the living manifestation of fire.
- Only Sane Man: Not to the same extent as Laymia, as he rarely takes anything seriously, but he's something of a mediator. If some pillars are picking fights each other, he'll be the one to break it up.
- Playing with Fire: Salamander's abilities revolve around flames, although they don't burn like typical flames do:
- Perpetual Smiler: He's always smiling. Always.
- Smug Snake: He thought he had complete control over both Oga and Tojo. He didn't.
- Soft-Spoken Sadist: Even though he always has a smile on his face and is even the one to break up fights between his comrades, he can be quite the sadist at times. See White Hair, Black Heart.
- White Hair, Black Heart: In the manga (his hair is orange in the anime). The callous, cheerful way he described how Hilda's memories, including the memories of all her friends and especially Beel, shows that just because he's merciful to his subordinates and comrades, he's not really all that good of a guy.
A clown-themed Pillar Baron. He doesn't like fighting much, and instead prefers to play games with his enemies.
- Affectionate Nickname: Some of the others call him "Coatl".
- Attack Reflector: Any violence done in his game rooms will be directed at the attackor, leaving the victims completely unharmed.
- Cloudcuckoolander: He can be a bit... weird, at times.
- Deadpan Snarker: He has moments where he's either this or The Comically Serious. For instance, when explaining the rules of a Sudoku puzzle (which Oga must complete in order to get to Hilda) to Oga, we get this:"'Sudoku.' Have you heard of a puzzle with such a name? It's a simple game, where you place numbers from 1 to 9 into the squares. However, you can't use the same number twice within a box, or within vertical and horizontal lines... and he died before I managed to finish my explanation."
- Eerie Pale-Skinned Brunette: Though it may be makeup, his skin is extremely pale.
- Fashionable Asymmetry: A downplayed example: what with being a clown, his clothes are half white and half black; his hat and pants are black on his right side and white on his left, while his shirt and shoes reverse this.
- Graceful Loser: Mostly. While he does say "This can't be..." after all four of his games are beaten almost simultaneously, he does not try to stop Oga and Tojo from advancing.
- Major Injury Underreaction: When Oga lands a powerful punch to his face, Coatl's only reaction is to comment, "You're hurting me."
- Nice Hat/Happy Harlequin Hat: He wears a nifty-looking jester's hat, although it has only two bells and is decidely less floppy and more stationary than most examples.
- Non-Action Guy: He doesn't fight, preferring instead to play games.
- Not-So-Harmless Villain: In a sense. He's a Non-Action Guy who doesn't even seem to have offensive magic at his disposal. Amusingly enough, though, whereas other Pillar Barons couldn't even slow them down, he actually managed to stop Oga and Tojo by making it impossible for them to pass unless they completed a Sudoku puzzle. If the (more intelligent) cavalry hadn't picked that moment to show up, they would have been completely stone-walled. Even more amusing is the fact that this wasn't his intention: he just made the thing (and the other three puzzles) because he was fascinated by human games when he came to the human world, and then he implemented them in the battle so that they wouldn't go to waste.
- Perpetual Smiler: Even more so than Salamander, who at least dropped his smile after he got his lights punched out. In keeping with his clown theme, Coatl seems to be literally incapable of making his face do anything except smile.
- Villainous Harlequin: He's not actually a clown, but he does have the aesthetic.
The first Pillar baron shown in the series, he is the direct superior of Graphel and Hecadoth. After the three of them were defeated by Zenjuro Soutome, they came back to finish the job of assassinating Oga.
- Older Than They Look/Improbable Age: He's one of these two. He looks to be about Lamia's age, which means he's either an 11 or so year old Baron, or he's a lot older than he looks.
- Light Is Not Good: He has the ability to summon angels. This does not make him any less ruthless.
- Perpetual Frowner: The expression you see up there is the one he's always wearing.
- The Stoic
- You Gotta Have Bluehair: But he's a demon, so we'll let this pass.
Vritra is a female Pillar Baron who really doesn't look it. She's extremely stoic and never really emotes at all.
- Adapted Out: She doesn't appear at all in the Anime.
- Badass in a Nice Suit: Notable in that, aside from Laymia, she's the only Pillar who actually wears it instead of a custom uniform.
- Bifauxnen: Bordering on Ambiguous Gender.
- The Comically Serious: Especially apparent when she interracts with Salamander. Whenever he says something weird or something that does not at all reflect the seriousness of the situation, she'll go along with him.
- Not a Morning Person: Apparently because of her low blood pressure, she always wakes up in a bad mood.
- Royal Rapier: Her weapon of choice seems to be one of these.
- The Stoic: Even more than Laymia.
A Pillar Baron and Graphel's brother. He is aloof and arrogant, and wields a katana.
- Arrogant Kung-Fu Guy: He's quite arrogant in the face of enemies.
- Iaijutsu Practitioner: He can apparently draw, strike with, and sheath his blade at supersonic speeds.
- Jerkass: He's one of the less likeable members of the Division. In fact, his opening scene has him suggesting they execute two comrades for acting without permission, and it's later revealed that one of the men he wanted to kill was his own brother.
- Katanas Are Just Better: He seems to think so, but Tojo proves him wrong by breaking the blade with his bare hands.
- Strong Family Resemblance: To his brother, Graphel. Tojo even got them mixed up.
- This Cannot Be!: He has this reaction when Tojo breaks his sword.
The third female Pillar Baron and a powerful demon. She doesn't talk much but is a strong fighter.
- Adapted Out; She gets one or two incidental, non-speaking appearances in the anime.
- Anime Chinese Girl: Her appearance definitely has shades of this trope, although personality wise, she's actually not all that similar.
- Bare Your Midriff: See Custom Uniform of Sexy.
- Custom Uniform of Sexy: Instead of a double-breasted suit, she wears tight knee-length shorts as well as a halterneck style shirt that leaves her abdomen exposed.
- Dark Action Girl: Her ruthlessness and tendency to hit opponents in the back suggests she is more this than she is a true Action Girl.
- Odango Hair/Girlish Pig Tails
- The Stoic: Her expression seems to be locked in "melancholic."
Agiel is the first Pillar General and a Blood Knight to rival Kenpachi. She uses a sword and doesn't really wear much.
- Affably Evil: A little bloodthirst aside, she's really polite.
- Blood Knight: She's right up there with Tojo and Jabberwock.
- Braids of Action/Girlish Pigtails
- Chainmail Bikini: Her outfit in a nutshell.
- Curtains Match the Window: In the manga, she has dark pink hair and matching eyes.
- Custom Uniform of Sexy: See Stripperific.
- Cute and Psycho
- Dark Action Girl: Though she got worfed by Takamiya, she's still the only one of the Pillar Generals fighting him to be capable of walking away from the battle, and she even had enough strength to carry her comrades away with her.
- Defeat Means Respect: She starts fixating on Aoi after the latter defeats her.
- Face–Heel Turn/Enemy Mine: She switches to Aoi's side when two Pillar Barons are about to gang up on her. However, she only did this so that she could fight Aoi one-on-one later, and it's obvious their alliance was temporary.
- Friendly Enemy: To everyone in general but she really turns it up a notch for Aoi, though it seems one-sided on her part at first.
- Genki Girl: She's always energetic and cheerful. In fact, in her first scene, after getting tied up by Nene, she simply looks at Odonel and says, "Look, Odonel!! We match!!"
- In Love with Your Carnage: Again, to Aoi.
- Nice Hat: It's a cross between a pirate's hat and a college graduate's hat.
- The Only One Allowed to Defeat You: She feels this way towards Aoi to the point that she switched sides when Aoi was being overwhelmed.
- Psycho Lesbian: It's never outright stated, but she's definitely got some sort of feelings for Aoi, and despite her stripperific outfit and how touchy-feely she gets around Aoi, she's never shown even flirting with any men.
- She actually doesn't mind Furuichi either but she seems to do it for the lulz.
- Say It with Hearts: She does this a lot, especially when she's around Aoi.
- Sexy Spectacles: Her glasses are almost definitely only there for added fetish appeal.
- Stripperiffic: Agiel wears a Chainmail Bikini, a pillar coat, and a hat. And at one point she loses the coat.
- Rose-Haired Sweetie: She fits most of the personality points, though she is a bit more violent than is the norm.
The fifth Pillar General.
Hecadoth is the Eighth Pillar General and the first one to make an appearance in the series. He is also the first Pillar demon to be contracted by Furuichi.
- Badass Longcoat: What he wears most of the time over his uniform.
- Bishounen: He does look rather handsome and his long black hair doesn't make him any less good-looking.
- Facial Markings: He has the standard mark that all Pillar Generals have.
- Jerkass: He is somewhat of a jerkass, especially when he spears Hilda through the stomach and later on, he nearly chokes Yolda for being a negative influence on Lord En after Hilda defeats her in Himekawa's apartment.
- Little Bit Beastly: He has the standard fin ears that most members have.
- Long-Haired Pretty Boy: Long black hair.
- My Master, Right or Wrong: He displays this when attempting to kill Oga so that Lord En can destroy humanity.
- Nothing Personal: When fighting Oga, Hecadoth tells him that he has nothing against Oga, but he will kill him because he's Lord En's enemy.
- Not Worth Killing: He tells this to Oga, saying that he can kill him whenever he wants to.
- Spear Carrier: His standard weapon is a spear.
- Undying Loyalty: To Lord En.
- Villain Forgot to Level Grind: While he dominated in his first fight with Oga he gets his ass handed to him on a platter after Oga trains and learns how to use Beel's power.
SEVEN SIN LORDSDemon caricatures of the Seven Deadly Sins; some of which are associated with the Ishiyama Upstarts.
BeelzebubA powerful demon lord, Gluttony of the Seven Deadly Sins and "Lord of the Flies", "Beelzebub" in the modern day is actually a family of demons - The only known Demon Lord Family, as they are currently the rulers of the Demon World. Back in the day, this was the name of the demon who would eventually become Beelzbub I, but in the modern day, this title belongs to Baby Beel, who is the successor to the lineage.
- Arc Words: Beelzebub's name. It's actually important that all of the throne successors have the exact same name, but there aren't many details as of why yet.
- Badass Family: Every child that inherited the name of Beelzebub has proven themselves to be worthy of the title.
- Badass Grandpa: The original Beelzebub, Beelzebub I, actually fought King Solomon (yes, THAT Solomon) himself.
- It is repeatedly stated that if Beelzebub III wasn't batshit crazy with basically zero attention span, he'd almost certainly have destroyed the earth by now.
- Feuding Families: Although Beelzebubs may be blessed with children, there is a downside: If the current Lord Beezlebub has too many children (read: more than one), demons are obviously going to create factions over in-fighting, and civil war will eventually start, threatening both the family itself and the entire kingdom.
- It Runs in the Family: Every single Beelzebub has had one odd quirk or another. Not even the same quirk - it's just that EVERY Beelzebub just so happens to be born with weird quirk which sticks with them for life.
- Legacy Character: The true nature of Beelzebub seems to be this; ultimatly, Beelzebub is the only Demon Lord who even has children to pass his legacy down too.
- Overly Long Name: Kaiser de Emperana Beelzebub. Seriously, that's the full name. It gets even longer when children are born, and only because they have to put numerals on the end of it.
- Royally Screwed Up: As the only Demon Royalty, this naturally occurs. Especially when the current Demon Lord Beezlebub is actually insane. And extremely forgetful.
- Succession Crisis: This happens if the previous Lord Beelzebub has had more than one son. Such as in the modern day, between Baby Beel and En. Considering En hasn't inherited the Beelzebub title (despite being the elder of the two), it's obvious who has the approval for being the true successor to the throne.
LuciferA powerful demon lord, Pride of the Seven Deadly Sins, who in the past fought the Demon Emperor for the throne and plunged the demon world into war. In a flashback it is shown that Takamiya's father and his associates found her asleep in a ruined castle and brought her home. When she woke up she curbstomped everyone in the house except for a young Takamiya.Appeared in person for the first time in chapter 207.
- Beat Still, My Heart: Maybe. She stabbed Furuichi in the chest and ripped out what appeared to be his heart but was actually his soul. It's not clear if she actually removed Furuichi's heart along with his soul, or if that's just the form his soul took when she ripped it out.
- Creepy Child: An emotionless elegant gothic lolita, who performs horrifying acts without any compunction.
- Curtains Match the Window: Eyes and hair are a pale grey.
- Elegant Gothic Lolita: Surprisingly, Lucifer turns out to be a little girl in a really, really frilly dress. Don't underestimate her because of that, however.
- Emotionless Girl: Her expression hasn't changed since her debut. Not even getting stabbed changed her expression, although she does reveal that she's emotionally attached to Takamiya.
- Knight of Cerebus: One of the very first things she does after she's introduced is stab Furuichi in the back and rip out his soul.
- Mystical White Hair: As befitting an immensely powerful demon lord in the form of a Creepy Child.
- Mythology Gag: Some surprisingly subtle ones to be found, especially considering Lucifer doesn't talk; for example, the fact she seeks the attention of her master, and will talk to him and him ALONE, which almost certainly has great implications if you know Lucifer's original story, and how she is almost always unemotive until you make a move against her master, at which point she tries to kill you with everything she's got, referring to The Devil Tarot card. A more obvious one is her King's Crest, a symbol representing an angel.
- Power Floats: Gets around by levitation.
- Power Incontinence: Comes with being, you know, Lucifer - it's stated just how dangerous it is to be her contractor, simply because Lucifer's power WILL kill you all on its own unless you can suppress it or siphon it off to others.
- Shapeshifter Weapon: She appears to able to morph her limbs into blades.
- The Speechless: In a flashback it is shown Lucifer appears unable to physically speak.
- Suddenly Voiced: In chapter 220, after saving Takamiya.
- Taking the Bullet: She took the second stab attempt towards Takamiya from a Solomon Company member that was trying to kill him.
- Telepathy: She has some form of this as she was able to show Oga Takamiya's memories of how he and Lucifer met.
- Your Soul Is Mine: She rips out Furuichi's soul, and then she cuts it into pieces and scatters them.
MammonA powerful demon lord, revered as Greed of the Seven Deadly Sins, and contracted to Kankurō Akahoshi. He makes his first appearance in chapter 221.
- Adam Smith Hates Your Guts: You want him to do anything for you, like, say, actually physically appear? It'll cost you. You want him to actually use a specific power? That's going to cost you more. You want to be his Master? You better be advised by a lawyer first, because it's going to cost you. Apparently, Akahoshi's tab is currently 500 pages long and going strong, due to him never having any money on him.
- Beware the Silly Ones: He may charge outrageous amounts of money to do ANYTHING from his master and wear something even your grandma wouldn't wear around his head, but he is powerful enough to extend Furuchi's lifespan so his soul doesn't instantly disappear come sunrise.
- Broken Pedestal: Let's just say that Mammon's physical appearance is disappointing by even the DEMONS' standards.
- Greed: It's MAMMON. You know, the same Mammon said to be the very embodiment of the sin.
- Miser Advisor: He will take any opportunity to make some cash. And we mean ANY opportunity, even the most ridiculous ones.
- Playing with Fire: He can use powerful fire magic, or at least Akahoshi can through their contract.
- Screw the Rules, I Have Money!: It's apparently one of Mammon's abilities: if you pay him, he can bend certain rules, even some of the set-in-stone ones.
SatanA powerful demon lord, Wrath of the Seven Deadly Sins. His reputation proceeds him.
- Ominous Fog: It's black. It also petrifies anything that breathes it. Oh, and it's filling the entirety of the town.
- Satan: The one and only, although he's not actually the ruler of the Demon World.
- Taken for Granite: How his power manifests - his contractor can use it on anyone that doesn't have any supernatural links, but Satan himself can use it on anyone and anything.
- Moment Killer: For Aoi.
The Demon King
The Demon King/Beelzebub the III
- Voiced by: Hiroki Takahashi
- Cloudcuckoolander: The guy is INSANE. No, really. It's for the best, though, as his extremely flighty personality seems to be the only reason he hasn't done his job.
- The Faceless: Not once have we ever seen his true face. Played with when he sends Beel and Hilda a video message - the camera is pointed at his crotch, and he is too embarrassed to show his face afterwards.
- Horned Humanoid: They're very cartoonish looking horns at that. It could be a helmet, but probably not.
- Ominous Opera Cape: As if he wasn't stereotypically evil enough.
- Phrase-Catcher: "The Demon King sure is random..."
- You Gotta Have Blue Hair: Green, matching his sons', although his seems to be a bit darker than theirs.
Baby Beel's mother. Shortly before the series began, she got into a fight with her husband the Demon Overlord because he's a deadbeat loser. Her telling him to get off his ass and do something productive is what caused him to send Baby Beel to destroy the human world in the first place.
- Cool Big Sis: Hilda stated that Iris was this to her.
- Horrible Judge of Character: She thought Johan, the Reaper of Solomon, was trustworthy, even though he had only been using her from the start.
- Ill Girl: She's confined to a wheelchair and it's mentioned that she has poor health.
- Missing Mom: To Baby Beel, though not by choice. As it turns out, she got into a fight with the Demon Overlord ("My husband, the Overlord, is a textbook example of a deadbeat husband.") and told him she was leaving for a while. She planned on taking Beel with her, but almost as soon as she said she was leaving, Beel was sent to the human world without her.
- Raven Hair, Ivory Skin: She's oddly Japanese in appearance.
- The Reveal: She's in L.A. and with the Solomon Company. Turns out she had a fight with the Overlord and came to Earth to try to protect it from the Overlord trying to destroy it. She got involved with the Solomon Company thinking they were helping her only to later find out they were using her as her power was key to controlling the Seven Sins.
- Silk Hiding Steel: She's calm and composed, she has poor health, and she looks like she couldn't hurt a fly. She also punched out the Overlord when she though he needed to get off his ass and do something.
- Unwitting Instigator of Doom: Twice over. First, the Demon King decided to destroy the world because she wasn't there to convince him otherwise. Second, she went to join the Solomon Company to make up for the first mistake, not realizing they're evil and planning to use demons (including her son) as magic batteries.
A komainu living in the human world. Kunieda made a deal with him to let them use his powers against the demons.
- Chronic Backstabbing Disorder: He has betrayed Kunieda twice already, all for petty reasons attributing to his perverted nature.
- Dark Is Not Evil: He's a demon, and though his chibi form is pretty ridiculous, his true form is pretty menacing. However, he's not really Evil, per se, just a colossal, perverted douche.
- Evil-Detecting Dog: He gives Aoi a sixth sense.
- Heel–Face Revolving Door: He's switched sides several times now, teaming up with Aiba to get revenge on Aoi, and later helping Ringo against Aoi because he thought she was more attractive.
- Hell Hound: His true form is a massive lion dog.
- Loveable Sex Maniac: He asks every female he meets a lot of inappropriate questions, which usually results in him being beaten up.
- Our Demons Are Different: His powers and origins are different from those of the Demon World.
- Sleep-Mode Size: His picture above.
- Talking Animal: Justfied since he is a demon.
- Token Evil Teammate: Koma is a rather selfish jerk with little in the way of loyalty, meaning he's quick to turn on Aoi depending on his whims.
- Youkai: He's said to be much older and of a different kind to the other demons.
