The primary school setting of Beelzebub, basically filled with a buttload of delinquents. In essence, it's the school that no parent in their right mind would ever send their kid to. EVER. Ruled over by the pseudo-Student Council Tohoshinki, the students of Ishiyama High get into a whole lot of trouble, all of the time.

    Ishiyama High as a whole 

  • Academy of Adventure: Both the first and last arcs of the manga take place at Ishiyama High.
  • Asskicking Equals Authority: Being delinquents in an environment where there are no rules, this trope is in full effect. In fact, while previously all the students bowed down to Oga/The Tohoshinki, after being split up into smaller groups and sent to other schools for a while, nobody really recognizes the authority of Oga or The Tohoshinki because they've been out from under their rule for so long, forcing them to start the whole process of beating respect into one's enemies all over again.
  • Book Dumb: They "hate studying 180%!" Also when it comes to standardized tests, the smartest in the school is apparently Furuichi. Note that these tests for were elementary school subjects. Though some of the smarter kids like Natsume and Himekawa didn't even bother trying.
  • Japanese Delinquents: Its delinquency level is 120%.
  • Mooks: A lot of the guys Oga finds in his quest to be rid of Beel are generally this.
  • No Teacher School: Understandably, there's not ONE to be found anywhere on the premises. The principal handles janitorial duties, as that's the only thing he could possibly have control over.
  • One-Gender School: Ishiyama is thought to be this at first, until you meet Kunieda and her crew. However, the gender ratio is still way off, though for understandable reasons.
  • Slobs vs. Snobs: Which ends up culminating in a most epic match of volleyball between the Ishiyama High delinquents and the pristine elite of St. Ishiyama.

    Tatsumi Oga 

Tatsumi Oga


Takayuki Furuichi


The Tōhōshinki

The four leaders of the delinquent forces at Ishiyama High. Tōhōshinki is an acronym of their respective last names; Hidetora Tojo, Aoi Kunieda, Hajime Kanzaki, and Tatsuya Himekawa.

They serve as the primary antagonists for the first part of the manga. Their conflict with Oga was caused by his quest to find someone even stronger and more evil than himself on whom he could force Beelzebub, which they took as him trying to usurp their power.

The Tōhōshinki aren't a coherent group but rather rivals who fought amongst themselves for domination of Ishiyama (except Tōjō who didn't much care about the whole thing and even had problems reorganizing the others). This comes to an end after Oga defeats them and briefly unifies the school under himself.

    The Tōhōshinki as a whole 

  • Absurdly Powerful Student Council: The Tohoshinki are technically this. Since this is basically a No Teacher School (with the exception of the principal, who mainly does the janitorial duties, and the lunch lady) that's ruled by the students, the Tohoshinki, being the strongest delinquents of the entire school, are the Student Council. Since Oga defeated all of them, he's basically the Student Council President, and by default, ruler of the school.
  • Badass Crew: Not just the Tōhōshinki, but also their respective followers, become this under Oga.
  • Balance of Power: They're not the nicest of people, but after Oga starts beating them, lower-level delinquents who they previously held in check start getting out of hand.
    • In fact, due to the fact that all of Ishiyama was spread around while it was being reconstructed (twice), the Tohoshinki and Oga were unable to keep them all in check, and now over thirty groups are vying for the top spot, and they plan on taking out the Tohoshinki and Oga first.
  • The Dreaded: Even after their defeat at the hands of Oga, their reputations were enough to keep lower-level delinquents in line. The only reason why it doesn't affect the current Ishiyama is because the school has been spread out for so long; otherwise their reputations are enough to control anyone outside of Ishiyama High.
  • Enemy Mine —> Friendly Enemy —> Fire-Forged Friends: First Kanzaki and Himekawa team up with Oga to take down Tojo, and after that all four have to team up with Oga to deal with Saint Ishiyama, with finding En, and then with the demons from Akuma Academy. The constant teaming up has been slowly and tactfully making them much more friendly with each other. By Chapter 211, three out of four of the Tohoshinki are now part of Beel's King's Crest, implying that they have certainly become Fire-Forged Friends. By Chapter 217, all four of them are revealed to be part of it.
  • Four-Temperament Ensemble: Sort of. Kanzaki seems to be choleric, Himakawa is sort of phlegmatic, Aoi tends to be melancholic, which leaves Tojo to be... ARE YOU KIDDING?!
  • Undying Loyalty: The King's Crest is only given to those who have sworn their allegiance to a king. As of Chapter 217, it is revealed that all four of the Tohoshinki have Beel's King's Crest, signifying their loyalty to Oga.



Hajime Kanzaki
King's Crest: Back, #1

Voiced by: Tomokazu Sugita

The first boss taken on by Oga in his quest to be rid of Baby Beel. Kanzaki's gang was one of the most feared gangs in Ishiyama, and his reputation for malice and extreme violence was the reason Oga sought him out in the first place. However, after Kanzaki humiliates and attacks Shiroyama, his most loyal subordinate, an enraged Oga defeats him, upon which he loses his reputation and much of his retinue, save for Natsume and Shiroyama.

Kanzaki has mellowed out much after his defeat, beginning to consider Natsume and Shiroyama as friends rather than subordinates, and became much more loyal to Oga and the rest of his schoolmates in Ishiyama.

  • Bad Boss: He initially treated everyone under him like crap. He still does, but in a more Jerk with a Heart of Gold manner, and he takes offense to others treating his subordinates like crap.
  • Berserk Button: Pulling that chain on his face looks awfully tempting, but it gets him seriously pissed off and gives him a huge power boost.
    • Also, don't make his niece Futaba (manga) cry. She's a brat, yeah, but he still cares about her.
  • Big Damn Heroes: Chapter 216 - he and Beel pop in to save Yuka and the other non-powered Ishiyama students from Takamiya's King's Crest powered goons, before rushing off to destroy the device sealing Oga's power off from Beel.
  • Captain Smooth and Sergeant Rough: He plays the Rough role as one of Those Two Bad Guys.
  • Clasp Your Hands If You Deceive: He does this when he tells his niece that the real Santa is dead and the Mall Santa is an imposter, to avoid her giving him orders on what to tell Santa to get her for Christmas.
  • Empowered Badass Normal: Thanks to the King's Crest.
  • G-Rated Drug: His love of "yogurti" milk is sometimes shown as this. In the cooking challenge, no matter what Yuka did he kept adding it to the dish, while his first fight with Oga was over Oga buying the last carton for Beel, he used yogurti as his avatar's head during the war game before everyone made him change...
  • Hot-Blooded: He's very impulsive, and this tends to get him into a lot of trouble when he doesn't realize he's being outclassed.
  • Hypocritical Humor: When someone tries to use his niece as a hostage, Hajime calls them on it... only for his subordinates to point out that is exactly the sort of thing he has done before.
  • I Can Still Fight!: He and Himekawa pull this trope while fighting Tojo's underlings.
    • Also tries something similar during the rooftop battle with the Six Knights.
  • If You're So Evil, Eat This Kitten: His way of testing Oga's loyalty to him (asking him to throw Shiroyama out of the window); it predictably backfires.
  • Jerkass —> Jerk with a Heart of Gold: He's an arrogant prick, but he cares deeply for his friends and considers them his True Companions. In fact, he was possibly the most enraged out of the main cast when Himekawa turned traitor.
  • Kick Them While They Are Down: He would enjoy partaking in this, especially in his earlier appearances.
  • Miles Gloriosus: He heads down this path after Oga beats him. He's a good fighter that gets into fights WAY over his head. It's Subverted when a chapter in the Return to Ishiyama Arc shows him to be aware of his poor track record when it comes to fights, and reveals his tendency to recklessly attack is an attempt to prove to himself that he's not a wimp.
  • Odd Friendship: With Yuka.
  • Overshadowed by Awesome: By his own teammates. Kanzaki seems to be of average intelligence, and he's a skilled fighter. It's just that Oga and Toujou are absolute monsters, and Himekawa is a Manipulative Chessmaster. Eventually, he Took a Level in Badass to compensate for this, and near the end of the Return to Shiyama Arc, he goes on a rampage that permanently establishes his badass cred.
  • Perpetual Frowner: He's always got a bored, disinterested frown on his face.
  • Roaring Rampage of Revenge: He goes on a short-lived one when Shiroyama is beaten into unconsciousness with dumbbells. Unfortunately, Miki takes him out.
  • Savvy Guy, Energetic Girl: He has this dynamic with Yuka.
  • Those Two Guys: In early chapters, after both were defeated by Oga but before either of them really got any characterization, he had this going with Himekawa.
  • Took a Level in Badass: At the end of chapter 193, he becomes the first of the Tohoshinki to gain Beel's King's Crest, revealed in chapter 194 to be the mark of a vassal. He then proceeds to beat the ever-loving shit out of a group of magically empowered delinquents who were mopping the floor with him earlier.
  • Trademark Favorite Food: Absolutely no one is as addicted as he is to yogurt drinks.
  • Undying Loyalty: Hilda reveals that the "King's Crest" on Kanzaki is only given to those who have sworn life-long allegiance to a lord, so it seems that as much as he would hate to say it to his face, Kanzaki truly sees Oga as his boss. Furthermore, the lower the number of the crest, the higher the bearer's allegiance is to their king. Since Kanzaki is #1, that indicates the loyalty/trust between him and Oga is the strongest amongst the Tōhōshinki — which is saying a lot, considering that he beat out Kunieda, who is in love with Oga and was the first of the group to learn about demons.
  • Warmup Boss: Kanzaki is the first of the Tohoshinki that Oga comes across, and by far the easiest to deal with.
  • Yakuza: He's the second son of the Kanzaki-gumi oyabun, or family head.


Tatsuya Himekawa
King's Crest: Left Forearm, #3

Voiced by: Seiro Ogino

A member of the Tohoshinki and the second member that Oga takes on in his quest to be rid of Baby Beel. At first he is seen as a suave, devilishly smooth mafioso style guy, sporting an 80's style outfit and a ridiculous pompadour. After meeting Oga, however, we then see him become almost entirely useless.

Himekawa is the sole heir of a large financial zaibatsu, and almost always uses his immense wealth to have his way. Unluckily for him, his money was not able to buy Oga off, the latter promptly giving him the beating of his life. He now regularly uses his wealth to assist the Ishiyama Gang in their escapades, revealing an unexpectedly sharp mind in the process. He is also shown to be quite handsome when he doesn't sport his trademark pompadour.

  • A Lady on Each Arm: He's like this the first time we see him.
  • Arranged Marriage: He's been engaged to Kugayama (who's female) since birth. It turns out he knew about the engagement, just not to who. He didn't even know Kugayama was a chick.
  • Batman Gambit: He pulled one on the fly to avoid being expelled and to force a confrontation with the Six Knights, which not only saved him, Oga, and their group from being kicked out of the school, but also got the Six Knights to give up most of their authority.
  • Bishie Sparkle: Happens frequently whenever he lets his hair down, especially when he's introducing himself.
  • Bishonen All Along: Who would have thunk it? Shown here.
  • Bishōnen: With his hair down.
  • "Blackmail" Is Such an Ugly Word: He never outright says it, but considering some of his actions...
  • Captain Smooth and Sergeant Rough: He's the Smooth to Kanzaki's Rough, considering his use of bribery to get what he wants.
  • Characterization Marches On: He starts off as being a violent Smug Snake. Compare the Bishōnen Magnificent Bastard in the later episodes to his debut. He was also a womanizing jerk the first time we saw him, but this was dropped almost immediately.
  • The Chessmaster: Hoo boy. He fakes defecting during the Return to Ishiyama arc, wears a skin patch to disguise his King's Crest, and acquires a machine to cut off Oga from Beel...because he remembered that last time that happened, the power build up was immense and let Oga destroy a school with one punch. The second a spellmaster says the built up power is enough to handle Takiyama and Lucifer, he destroys the machine and dismisses it as pocket change.
  • Chick Magnet: He's proven himself to be very charming, and when he ditches the pompadour, girls flock to him.
  • Childhood Friends: With Kugayama. It's unknown whether she's Victorious or Unlucky, since it isn't clear what Himekawa's feelings on the subject are. Though the end of the arc heavily implies that while he is confused about the entire situation, he does still consider Kugayama his friend and isn't entirely opposed to their relationship evolving from platonic friendship.
  • Combat Pragmatist: This includes covering his chest with a ceramic plate and using a stun baton.
  • Cool Shades: See his picture.
  • Empowered Badass Normal: Thanks to his King's Crest.
  • Face–Heel Turn: Sort of.
  • Fashion Dissonance: Caught somewhere between Awesome Anachronistic Apparel and Outdated Outfit, Himekawa and that forward beehive of his stand firm.
  • Fiction 500: Comes from a wealthy banking family. Apparently his monthly allowance is in the hundred-thousands and he considers spending millions pocket change (he has only been out of money once and that was in a filler episode. To date he has: owned the top seven floors of a high rise apartment complex, bought an entire gaming company on a whim, and spent several million on a demon-sealer that he always planned to destroy. He also has access to what is assumed to be a very expensive penthouse in a resort location. And his family owns an island shaped like a pompadour.
  • Guile Hero: While he's nowhere near Toujou (he only beat a normal Toujou when he himself had a powerful King's Crest, and even then, he took quite the beating) or Aoi's level, he's pretty handy in a fight. His most dangerous weapon by far, though, is his intelligence and cunning.
  • High School Hustler: His tendency to use his reputation and vast fortune to manipulate the delinquents at Ishiyama makes him this.
  • Honesty Is the Best Policy: Telling Oga that he was infiltrating the Fallen Angels as part of a ruse.
  • I Can Still Fight!: He and Kanzaki pull this trope while fighting Tojo's underlings.
  • I Just Want to Have Friends: Subtly alluded to throughout the series.
    • By the Demon's Painting arc, we find out that his best friend when he was a kid betrayed him, and he hasn't really been able to trust anyone since. Finding out said best friend was a girl and in love with him may have messed with him even more.
  • Jerkass -> Jerk with a Heart of Gold: He starts out as a selfish, greedy, womanizing prick, but while his abrasive personality never really goes away, he becomes much more willing to help out his friends. A perfect example of this is his tendency to pay ridiculous sums of money on his friends' accounts, and then claim that this money is just pocket change, almost lording his money over them yet still helping them out. Still an asshole, though
  • Lonely Rich Kid: As we find out in later chapters.
  • Long-Haired Pretty Boy: The pretty you'll find out later.
    • He seems to resent having his hair down though, as he is irritated when it's changed involuntarily.
    • An employee of his family's in a filler episode revealed that his fighting power is halved when his pompadour is not up. This may or may not be canon, as he was shown training with his hair down in the manga's Akumano arc and so should be taken with a grain of salt.
  • Not-So-Harmless Villain: Whenever he can't throw his money around he's usually lumped in with mediocre fighters like pre-badass Kanzaki, but then he electrocutes an entire gang with a custom taser-whip and coolly drops one of them off a high rooftop just to prove a point.
    "We have to teach you to never oppose us, ever again."
  • Only Sane Man: Not like Furuichi or Aoi, though, as he's Locked Out of the Loop regarding the demons. Until the Return to Ishiyama arc.
  • Out-of-Character Moment: During a conversation with Kuguyama, he says that there are things in this world that money can't buy. Furuichi is shocked to hear this.
  • Sarcastic Confession: When Oga demands to know what he's doing with Takamiya's group, Himekawa tells him in front of Takamiya's people that he's a Fake Defector. But because they know that Oga is kind of an idiot and Himekawa is a liar, they readily believe that he was just lying to make Oga go away.
  • Screw the Rules, I Have Money!: His philosophy in life is that if you can't beat 'em, buy 'em. It didn't work so well with Oga, however.
    • He uses it again when playing a videogame against En and his maids... but to be fair, he didn't use this trope until the other side started to cheat.
    • And again to buy a demon sealer.
  • He Cleans Up Nicely/Letting His Hair Down: "Hime" sure is bishounen when his hair isn't in that ridiculous pompadour and he takes his glasses off... to the point that no one recognizes him.
    • Furuichi referred to it mentally as Himekawa's "Super Pretty Boy" mode.
  • The Smart Guy: At least as far as the Tohoshinki is concerned. The others frequently comment on how useful he is. The fact is, most of the other characters have no idea what exactly he's doing, but there's no doubt that things would be much harder for the protagonists, who are of average intelligence at best and are dumb as bricks at worst, to succeed in most of the major conflicts int the series.
  • Stun Guns: His preferred melee weapon.
  • Those Two Guys: In early chapters, after both were defeated by Oga but before either of them really got any characterization, he had this going with Kanzaki.
  • Took a Level in Badass: In chapter 202, he took down Tojo, of all people.
  • Undying Loyalty: The King's Crest signifies sworn allegiance to a king. It was originally believed that Himekawa was loyal to Takamiya, by virtue of having his King's Crest — but he used a fake patch of skin to pretend to have Takamiya's King's Crest and to hide Beel's King's Crest, indicating that his loyalty has always been to Oga and no one else.
    • He's later questioned on this trope by Fuji. Himekawa laughs in his face and declares that not understanding this concept is why Fuji will not beat Oga in the end. Given that Himekawa is being turned to stone simply to slow Fuji down, it was very clear he still embodies the trope as well.


Aoi Kunieda
King's Crest: Left Pectoral, #2

"I can't let anybody see that the leader of Kantou's strongest ladies, The Red Tails, is taking care of a baby."

Voiced by: Aki Toyosaki

Aoi is a 17-year-old that leads an all-girl delinquent group in the school, the Red Tails. She uses a wooden sword to fight with and is one of the best fighters in the series thus far. She has a crush on Oga, but won't admit it to anyone, including herself. She quit the Red Tails, but still fights and hangs out with them. She dons a disguise and a fake name when taking care of her little brother in the park or other places so as not to be embarrassed or confused as his mother. Especially in front of Oga. She is almost always seen with her two henchman/friends Chiaki and Nene After her first encounter with Behemoth's subordinates she becomes the second person to learn the true nature of Baby Beel.

  • A Mother to Her Women: She's very protective of her fellow gang members, but also very forgiving. Completely unwilling to attack or harm her fellow members for any reason. Even when some of them betray her, she was unwilling to fight back until she had taken a level of badass high enough to defeat them all without harming them too much.
  • Absurd Cutting Power: She swings her wooden sword once and glass is cut twice. Also, stone and concrete walls don't hold up very well in the face of her actual techniques. This is a part of her family martial art style - Shingetsu. One of the basic principles and techniques is called "Nadeshiko"; it allows her to cleanly split a stone the size of her head cleanly in half with an open-palm strike by channeling her energy. This is how she manages to cut Sakaki's bokken in half with just a ruler.
  • Action Girl: There's a reason she became one of the Tōhōshinki and she's continued developing her skills over time.
  • Amazon Brigade: She used to lead the Red Tails as the 3rd Leader, which was composed of the entire female student body.
  • Badass Adorable: She's pretty cute whenever she goes all deredere toward Oga.
  • Badass Longcoat: When she was leading the Red Tails. She gets it back in chapter 200, taking the leadership back from Nene.
  • Benevolent Boss: She clearly cares deeply for the Red Tails. She also allows Red Tail defectors to come back, but insists on tagging a few of their gang jackets with "fake" at the top.
  • Big Damn Heroes: When Oga, Himekawa, and Kanzaki were going to fight Tojo near the beginning of the series, the entire male student body showed up to stop them. Then Aoi and the Red Tails show up and start kicking ass.
    • She has one again in Akuma Academy to save Nene.
    • And yet again, during the Akuma Academy Raid to save Hilda, when she arrives to save Oga from fighting a horde of female demons.
  • Cannot Spit It Out: She just won't admit that she likes Oga to his face. Or to herself for that matter. She's getting better though.
  • Can't Hold Her Liquor: She gets very drunk at dinner with Suiten and Oga. Although in her defense, Suiten told her the Vodka was water.
  • Class Representative: After their transfer to St. Ishiyama, she was appointed as co-representative with Oga, tasked to keep the delinquents of Ishiyama in line.(Cue her girlish daydreams of doing patrol duty together with him) She's the only one taking the job seriously, however, as Oga prefers slacking off.
  • Clingy Jealous Girl: Become this when Oga and Hilda look like a couple.
  • Defrosting Ice Queen: It begins when she meets Oga, later followed by her departure from the Red Tails.
  • Does Not Like Men: Subverted. At first, she seemed as sexist as the rest of her crew, as it is the Red Tails' official policy not to rely on or date men, but actually she doesn't like frivolous and perverted men. After her fight with Oga, she left the group after meeting (and falling for) him. Since Furuichi had a hand in getting that particular rule abolished, she doesn't have to chose between the Red Tails and Oga anymore.
  • Dude Magnet: Played for Laughs. She's attracted quite a few suitors, including Aiba, Sakaki of the Six Knights, and Akahoshi.
  • Empowered Badass Normal: After dealing with a lesser god, she obtained power to fight against demons. She gets another one in the form of the 2nd King's Crest from Beel and Oga.
  • Even the Girls Want Her: A lot of the Red Tails really admire her, especially Nene, and then there's the Foe Yay between her and Agiel.
  • Girlish Pigtails: As Aoi Kunie.
  • Girl Posse: She has one. Chiaki, Nene, Yuka, and the rest of the Red Tails follow her more or less everywhere, and are the only people except Furuichi who notice her crush on Oga. They even threaten him not to take advantage of her, much to his confusion.
  • Implausible Fencing Powers: She can cut through concrete with a wooden sword, and that's in her first appearance (technically second, but she wasn't fighting in her first). Her abilities only get more implausible as time goes on.
  • Improbable Weapon User: She prefers a wooden sword, but she has used an umbrella and once a ruler. Yes, it was a pink, flowery ruler, and she used it to cut her opponent's wooden sword - IN HALF. She also destroys a small shrine with just a branch she took off a nearby tree.
  • Interrupted Declaration of Love: Thanks to Satan's Moment Killer.
  • Is That Cute Kid Yours?: People are constantly mistaking her little brother for her son and gossiping about how kids these days are so irresponsible. She does not approve.
  • Japanese Delinquents: She doesn't even seem to be the delinquent-type unless one sets off her surprisingly short fuse. During the park debut, when the cop was talking bad about both her and Oga, she was about to slap him for being a douche.
  • Love Triangle: She thinks she is in one, but Hilda does not love Oga ...maybe.
    • She is in another one, only with Aiba Izo having a crush on her, while Oga has no idea what is going on.
  • Mandatory Unretirement: The Red Tails just won't let her quit. She finally picks up the leadership again after having a nasty time with the former 2nd Leader of the Red Tails coming back.
  • Meganekko: Her alter ego "Aoi Kunie" is this.
  • Miko: Her family owns a shrine. She also dresses as one when training.
  • Mistaken for Cheating: She gets pissed off when she thinks that Oga has been cheating on Hilda with her, though he wasn't interested in either of them to begin with.
  • Muscles Are Meaningless: She has a petite figure and, unlike the male members of the Tōhōshinki, her muscles aren't all that defined. She's still the second most dangerous of them all. Justified in that her power comes not from strength, but rather from being ridiculously skilled in powerful techniques taught by her grandfather who fights demons as an exorcist.
  • No Shirt, Long Jacket: Her Red Tails outfit.
  • Only Sane Woman: Of Ishiyama's special class.
  • Paper-Thin Disguise: Her alter-ego, Aoi Kunie (which she adopted when taking care of Kota), is her wearing girly clothes, a bucket hat, and glasses with her hair in pigtails. Except the Red Tails, nobody in Ishiyama saw through her disguise. Especially Oga.
  • Parental Abandonment: Her dad is off doing solitary training, and her mom is looking for him.
  • Red Oni, Blue Oni: She's the Red to Hilda's Blue, and the Blue to Nene's Red.
  • Sarashi: Part of her Red Tails outfit.
  • Sitcom Arch-Nemesis: With Hilda on a regular basis.
    • Always Someone Better: Hilda is this for Aoi. Unlike most examples, Aoi generally becomes okay with the fact that Hilda is stronger than her. To be more precise, she's not happy with the situation, and she eventually wants to take Hilda's place beside Oga, but she isn't resentful.
  • The Smurfette Principle: Kunieda's the only female in the Tohoshinki.
  • Token Good Teammate: Aoi is the only one in Oga's inner circle who won't start beating people up for no real reason, and unless you insult her or do something that offends her sense of justice, she's one of the nicest people one could hope to meet.
  • Tsundere: She's so nice that she really isn't much of an actual delinquent, but when it comes to Oga she steadfastly refuses to admit she likes him even to herself despite stepping down as leader of the Red Tails since that would mean she couldn't date anyone. One admirer even finds it adorable how she manages to be tsundere while completely alone.
  • Undying Loyalty: Her reception of a King's Crest shows her loyalty to Oga and truly believes that he is THE leader, regardless of how unrequited her one-sided crush is.
  • Weak, but Skilled: She actually has difficulty even lifting a medium small rock, but then once she sets it down she splits it cleanly in two with a palm strike. She doesn't need strength with her style of martial arts and swordsmanship.
  • Wooden Katanas Are Even Better: Her standard weapon. During the Akuma Academy arc, she reveals she does have access to a real katana, although using it against regular delinquents is a bit much since she can cut damn well anything with just her wooden bokuto already...
  • You Gotta Have Blue Hair: She's occasionally drawn with blue hair in color spreads.


Hidetora Tōjō
King's Crest: Left Shoulder, #4
"If you've got a problem, then we'll settle it with fists."

Voiced by: Tomokazu Seki

The last of the Tōhōshinki to be introduced and by far the strongest one, Tojo (Tora to his friends) could have taken over Ishiyama any time he wanted if he actually cared about it. He loves nothing more than a good fight and has power to back it up, being the first man to ever beat Oga in a fight.

He's... actually a pretty nice guy who won't bother those who don't want to fight with him. He loves cute things like babies and cats. When he's not beating someone up he's usually working some kind of part-time job (exactly which job changes with each appearance).

After Oga destroyed Ishiyama High the two of them ended up in the same class (along with the rest of the main cast) and teamed up against the Six Knights. They get along now, which doesn't stop them from engaging in fights almost every time they meet.

Tojo has a past with Zenjuro Saotome, who took care of him when he was a kid.

He accidentally gets into a fight with some of Behemoth's demons and receives heavy wounds. He gets basic training from Zen on how to fight demons, and goes off on his own to train, later showing up to help at the end of the Akuma Academy arc.

  • Badass Normal: He doesn't possess demon powers. Doesn't stop him from kicking ass.
  • Berserk Button: Don't fuck with his friends. No seriously, don't. Because he's a Blood Knight, just beating his friends up is fine as far as he's concerned, but trying to kill them is not. When he thought Takamiya had killed Furuichi, he went berserk and with only a few punches, he started to do as much damage as Oga did with several powerful spells.
  • The Big Guy: Easily the tallest of the Tōhōshinki.
  • Blood Knight: Even more than Oga!
  • Charles Atlas Superpower: Every bit as physically strong as Oga if not stronger. When he fights an opponent who has a supersonic sword, he punches it and breaks it.
  • Cuteness Proximity: He apparently tries to adopt animals he finds on the street.
  • The Determinator: Probably the biggest in the series. After fighting Izuma, who was using demon powers most of the night, he takes on a full demon and holds his own.
    • Chapter 216: After losing the power of the King's Crest in the previous chapter and getting badly beaten, Tojo refuses to stay down. While Aoi and Kanzaki eventually encounter Beel, who powers them up individually, Tojo just keeps fighting and eventually knocks his King's Crest powered opponent to the ground, thinking he's feeling its power despite the fact that he wasn't even using it.
  • The Ditz: He makes Oga look smart.
  • Dumb Is Good: Other than possibly Kunieda, he's the nicest of the whole Tohoshinki. He's also definitely the dumbest.
    • When Saotome tried to explain that there would be demons ("akuma") Tojo thought he meant bears (a "kuma") and proceeded to go off to train fighting bears bare-handed.
  • Empowered Badass Normal: From chapter 211 onwards.
  • Friendly Enemy: He's like this with almost everyone. He's such a Blood Knight that he doesn't even seem to realize that fighting is something usually done between people who hate each other. The way he sees it, fighting is just a pastime, one he really, really enjoys, and he considers most of the people he fights good friends because of the difficult fights they give him, not in spite of them.
  • Gentle Giant: Despite being a 2-meter-tall Blood Knight, at heart he's probably the nicest person in Ishiyama. He also has teddy-bear pyjamas. Don't forget the time he oogled over a kitten and Baby Beel himself.
  • Graceful Loser: After Oga beat him, he took it surprisingly well.
  • Hypocritical Humor: At several points, he calls Oga an idiot. Except, he's really not the sharpest tool in the shed, and most of the time, when he corrects Oga, he's even more wrong.
  • Jerk with a Heart of Gold:Unless you are asking for a fight, he isn't a huge jerk, but even then, all he'll try to do is attack you (which he'll only do if you're strong enough to give him a challenge), and he won't actually have anything against you afterwards, even if you win.
  • Lightning Bruiser: He's strong (in terms of purely physical strength, likely the strongest character in Team Oga), very, very fast, and he's such a Made of Iron Determinator that his endurance is inhuman.
  • Made of Iron: Oga can kick people into concrete with half-hearted kicks, even while sick. Tojo blocked Oga's full-power kick with his forehead.
    • Has trained by fighting bears during the start of the Akumano arc.
  • Mall Santa: During the manga's Christmas arc.
  • Megaton Punch: Undisputed master of this.
  • Nice Guy: The only exception to this is when he's getting ready for a fight, yet even then, he'll only fight if his opponent wants to. If they don't want to fight, he usually won't force them.
  • Oblivious to Love: Seems that way at least in regards to his childhood friend Nanami Shizuka, given their interactions and Shizuka's own thoughts on it.
  • Pet the Dog: He's very fond of small, cute things like cats, and takes good care of Beel while they're together.
  • Punch! Punch! Punch! Uh Oh...: What most people go through when they fight him.
  • Real Men Cook: In the side story manga he is shown to be also a good cook.
  • Real Men Wear Pink: Despite being a Blood Knight and one of the greatest badasses of the cast, Tojo loves sweets and cute things.
  • Tiger Versus Dragon: He's the tiger to Oga's dragon. The character for tiger (tora) is also in his name.
  • Took a Level in Badass: As if he wasn't badass enough, at the end of Chapter 211, he's revealed to have gained Beelzebub's King's Crest a few days before, giving him access to demon powers. Cue Curb-Stomp Battle...
  • Triang Relations: A type 4 or 5 with Shizuka and Izuma, although he probably doesn't know it himself. See Oblivious to Love.
  • Undying Loyalty: Tojo's loyalty is more like Apollo Creed to Oga's Rocky. He started off as Oga's opponent, became friendlier after his defeat to Oga, and while he still sees Oga as a rival, Tojo has frequently had Oga's back in fights and will do almost anything that Oga asks him to. His loyalty to Oga later rewarded and proved by him becoming the fourth person to receive Baby Beel's King's Crest.
  • Unskilled, but Strong: He isn't a particularly skilled combatant like Aoi is, but he more than makes up for it with his overwhelming power, speed, and endurance.
  • The Worf Effect: Usually to show how much of a threat something is, such as Furuichi while channeling the Pillar Squad or later having Himekawa, now with a King's Crest, defeat him.
    • Worf Had the Flu: In the Fuji arc he is turned to stone like all the rest, but Kunieda points out he knew it was coming and defended a shield generator from 100 attackers before he fell.

The Saints

The Ishiyama High students who were transferred to Saint Ishiyama Academy, hence the unofficial name other groups of Ishiyama High have given them. With the exception of MK-5 and "Good Night" Shirokawa, they are all subordinate to one of the Tohoshinki, and more or less loyal to Oga.

Kanzaki's Crew

Kanzaki's underlings. Back when he was still an antagonist, there were more of them, but after his defeat, only the two most loyal, Natsume and Shirokawa, stuck with him.


Shintaro Natsume

"This looks interesting..."

Voiced by: Daisuke Kishio

A laid-back subordinant of Kanzaki.

  • Big Damn Heroes: Seems to be making a habit of this.
  • Bishōnen: How pretty he actually looks seems to vary though.
  • Brilliant, but Lazy: He's clearly one of the strongest fighters around, but just can't be bothered to get serious.
  • Cavalier Competitor:
    "It's not really my style to go all out in a fight, you know."
  • Comedic Sociopathy: The guy gets his kicks from watching (and then joining in) potential battles as they develop and unfold.
  • Curb-Stomp Battle: Every one-on-one fight he's been in.
  • Dissonant Serenity: Cheerfully laughs when the demons have taken over Ishiyama High, brainwashed the students, and practically declare all-out war on the gang.
  • Even Evil Has Standards
  • Faux Affably Evil
  • Hair Flip: Very fond of running a hand through his hair. The anime also animates it flipping prettily while he's in action.
  • Hidden Depths: Maddeningly so.
  • High School Hustler: Episode 14 shows his potential for zany schemes and the beginnings of manipulative tendencies.
  • Hypercompetent Sidekick: Kanzaki ought to be his sidekick, not the other way around.
  • Let's Get Dangerous!: Against the Six Knights, and then against Onizuka.
  • Mr. Fanservice: He's pretty good looking, in addition to having a Modesty Towel scene.
  • Perpetual Smiler: If he stops smiling, bad things will soon happen.
  • Servile Snarker: To Kanzaki, only because when he's around, there's bound to be a fight happening.
  • Tranquil Fury: Except on a few rare occasions, it's hard to tell when he's angry or just bored. On those rare occasions, however, he still remains calm and collected.
  • Wild Card: Is stronger and more intelligent than he lets on, bordering on Obfuscating Stupidity. His actual motives have yet to be explored, however, and he remains one of the most mysterious characters in the series. Well, unless he was telling the truth about finding hanging around Kanzaki to be fun and interesting.


Takeshi Shiroyama

Voiced by: Kenji Nomura

A hulking nice guy recognizable by his girly pigtails. Extremely loyal to Kanzaki.

  • Butt-Monkey
  • Gentle Giant: With the exception of his pigtails, he's the very image of a brutish, violent thug. He's also one of the nicest characters in the series.
  • Girlish Pigtails: Overlapping with Braids of Barbarism. Very, very rare male example of this and not exactly played for laughs.
  • Minion with an F in Evil: One wonders exactly why he's so attached to Kanzaki.
  • Nice Guy: He becomes one of the nicest characters in the series. For instance, when he stopped three St. Ishiyama students from harassing some of the Red Tails, and they called him out for cockblocking them, he let them each hit him once in compensation. Even when they started dropping dumbbells on his head, he wouldn't fight back because he thought he owed them.
  • Yes-Man: To Kanzaki, bordering on Undying Loyalty.
  • You Have Failed Me: Gets this as well as a Kick the Dog moment from Kanzaki after failing to dispose of Oga.

The Red Tails

A group comprising all of the girls in Ishiyama High. Basically they all really, really don't like guys. Was once headed by Aoi Kunieda, with her cohorts Nene and Chiaki; however, Nene has now taken over as the 4th Leader.

    The Red Tails as a whole 
  • Amazon Brigade: Exaggerated; not only is the gang all female, every female in the school is a member.
  • Badass Longcoat: Their uniform is a long white coat with their name on the back.
  • Does Not Like Men: The reason for their existence, until chapter 178 when Furuichi has Misaki, the founder, tell them to "break a boring law like that."
  • Improbable Weapon User: See the individual entries for some examples.
  • Those Two Guys: Two of them, Yuka Hanazawa and Ryoko Asuka, turn up pretty often. Now that Yuka has a more major role, Ryoko is instead paired up with another short-haired member named Kaoru Umemiya.


Nene Ōmori

Voiced by: Ayahi Takagaki

The new leader of the Red Tails after Kunieda leaves. Nene's main objective is to get Kunieda to take her old position back.

  • Beauty Mark: Under her left eye.
  • Can't Catch Up: While she isn't at the monstrous level of fighters like Oga, Toujou, Kunieda, or even Ringo, Nene is an extremely competent fighter. However, given how she often goes up against demon-powered enemies and has a tendency to find herself in situations where she's extremely heavily outnumbered, her track record isn't that good.
  • Chain Pain: Her standard weapon is a chain she uses like a whip.
  • Does Not Like Men: She enforces this vigorously as per being a Red Tail. She never quite forgave Oga for being the one to make Kunieda retire. She does seem to have a soft spot for Furuichi, but she might just feel sorry for him.
  • Fangirl: She freaks out when she gets to talk to the Founder of the Red Tails on the phone.
  • Fiery Redhead: When dealing with men, especially men she doesn't like, her aggressive behaviour can come off as this.
  • Heroic Sacrifice: She performs one in the online war game, Taking the Bullet to save Chiaki. Being a medic, Chiaki heals her.
  • Ms. Fanservice: She takes a long, steamy shower when she knows someone is spying on her... while wearing a bikini in order to keep him from seeing her naked. She underestimates how attractive the peeper thinks she looks in the bikini, though.
  • Number Two: To Kunieda, even after Nene becomes the Red Tails' 4th Leader.
  • Red Oni, Blue Oni: The red to Aoi's blue.
  • Secretly Rich: Although it's not clear if it was a secret to everyone, or just Furuichi. Given the rather insular nature of the Red Tails, it's likely that at least the Saints faction of the Red Tails is aware of it.
  • Ship Tease: Gets a bit with Furuichi, both being the Number Two to Oga and Kunieda respectively, and also being the straight guy/girl in many of the craziness that happens around them.
  • Spikes of Villainy: When she goes to meet Misaki, she dresses up in an outfit featuring these.
  • Tsundere: (Type A) She seems to act this way towards Furuichi. Maybe.


Chiaki Tanimura

Voiced by: Aoi Yuuki

One of the Red Tails, who uses guns. Very quiet, but a respected member of the group.


Yuka Hanazawa

Voiced by: Haruka Tomatsu

Another Red Tail, and kinda crazy. She also considers Lamia absolutely adorable.

Tōjō's Crew

Less a gang and more just a pair of guys, Jinno and Aizawa, who follow Toujou around. Like him, they love a good scrap, but otherwise aren't all that bad.


Kaoru Jinno

Jinno is one of Toujou's friends as well as his left hand man. Unlike most of the cast, he's studious and actually quite responsible.


Shōji Aizawa

Aizawa is another of Toujou's friends and his right hand man. Cocky and laid back, he can be easily recognized by his slicked back hair.


When they were first introduced, these guys were said to be the most terrifying group in Ishiyama. Now, these guys are the laughing stock of the entire show.

    MK-5 as a whole

The Six Omens of Slaughter

A group of Ishiyama freshmen who were initially transferred to other schools. Each of them has gathered their own group of delinquents to serve under them, and each appear to be a serious contender for the rank of the strongest fighter of Ishiyama High.


Yōhei "Nasubi" Nasu

The first of the Six Upstarts to make an appearance. He and his group, the Poltergeists, have a musical theme going on.

  • Anime Hair: His hair is almost like an afro made up of straight hair that defies gravity.
  • Cloudcuckoolander: Although not in a charming sense. There is a reason Furuichi compares him to The Joker.
  • Dance Battler: Paired with super strength, for good measure.
  • Dissonant Serenity: The only time he ever lets his laid-back attitude slip is when Kanzaki reveals himself to have taken a level in badass.
  • Fanservice: Chapter 193 has him running around topless. Might also be Fan Disservice for some since he wears nipple tassels.
  • Knight of Cerebus: After a rather light-hearted arc, this guy comes along and knocks Oga into a wall.
  • Lack of Empathy: He sees Baby Beel as nothing more than a magical battery. His reason for wanting Beel is to use up all of his power before throwing him away when he runs out.
  • Musical Assassin: Each of his subordinates plays an individual instrument, while he himself seems to be some kind of dancer.
  • Red Herring: Seemed poised to be the most difficult to take down and Big Bad of the arc at first but is shown to be just a cog in someone else's plans.
  • Smug Snake: He and his crew are not nearly as competent as Nasubi thinks they are.
  • Villainous Breakdown: He sure didn't expect Kanzaki was capable of defeating his entire team, and he ESPECIALLY didn't expect Oga to stand up after having dozens of spell-fueled attacks thrown at him. And then Oga started to kick his ass...


Kankurō Akahoshi

Another of the Six Upstarts. He is contracted to the demon Mammon.

  • Attention Deficit... Ooh, Shiny!: Along with Oga, he got distracted from searching for Furuichi because they saw a crayfish in a gutter and decided to go fishing.
  • Big Damn Heroes: He and Ichikawa intervene when Solomon Company's Reaper was about to kill Takamiya and Lucifer, and managed to force him to withdraw.
  • Cloudcuckoolander: While he's more responsible and devious than Oga is, he's shown to be just as weird when they're looking for the mini-Furuichis. He comes up with the idea that they should put some honey on a tree to attract him to it, and later, he and Oga can be seen looking in sewer entrances, fully expecting to find him there.
  • Enemy Mine: He and Oga seem to have this going right now.
    • Friendly Enemy: By the time they officially decide to join forces, they'd pretty much already bonded.
  • Expy: You may remind him of Kyo Kusanagi. However, Akahoshi has a scar, unlike Kyo. Ironically, his name and fire spell casting matches the character based on him.
  • Hidden Depths: This guy knows quite a bit about the Solomon Company, and he even has his right-hand man following their movements.
  • Let's Fight Like Gentlemen: By the standards of the series anyway. Everyone's a delinquent, so Combat Pragmatism is the norm, but he seems like one of the few people who would rather fight one-on-one instead of jumping an enemy with his entire gang.
  • Only Six Faces: Most likely intentional, but he looks VERY similar to Oga. Later lampshaded.
  • Playing with Fire: Thanks to Mammon. He and two of his henchmen arrive with a blast of fire in Chapter 220, and later, in Chapter 224, he used a blast of fire to take down Libra.
  • Perpetual Frowner: This guy is always frowning.
  • Spell My Name with an "S": In his first appearance, his surname was spelt "Akahoshi," but since then, it's been spelt "Akaboshi."
  • The Stoic: He really doesn't emote much.
  • Worthy Opponent: He seems to view Oga as this.


Ebian Ichikawa

Another of the Six Upstarts.


"Tobacco" Ringo Hōjō

The leader of a Red Tails-splinter group who aims to overthrow Nene and by extension Aoi and become the leader of the whole gang.

  • Combat Pragmatist: She uses all means available to force Kunieda into fighting and losing to her. Not that it works. Oga turns this against her by pointing out all she's doing is saying she's not strong enough to beat Kunieda in a straight fight.
  • Evil Counterpart: To Kunieda. Whereas Kunieda left the Red Tails behind yet still cares about them, Ringo has declared herself the leader of the gang and treats her subordinates quite badly.
  • Good Smoking, Evil Smoking: Her's is decidedly evil. She's also notable for being one of the very few minors in the series to actually smoke, so much that it's even her epithet.
  • Jerkass
  • Luminescent Blush: Oddly enough, Ringo makes one of these towards Oga in chapter 201 moments after he told her that she's strong enough to fight on par with Kunieda without having to resort to dirty tricks.
  • Older Than They Look: She's 21 years old, making her the oldest out of the Six Upstarts.
  • Smug Snake: She's extremely smug, but without Koma's power, she's no match for even a normal Kunieda.
  • The Starscream: Implied to have been this after Kunieda deposed her as leader.
  • The Vamp: She tries to use her body to get Oga to let his guard down. Which is kind of a dumb move, as Oga is ely oblivious to things like that. Luckily for her, however, Beel was in Oga's body, so it worked.
  • Wooden Katanas Are Even Better: She and Aoi duke it out with wooden Katanas, and Ringo is actually pretty good with it. Not at Aoi's level, sure, but she still has some implausible cutting power.
  • Would Hurt a Child: Backhands Baby Beel (thankfully Oga was in his body instead).


Shinobu Takamiya
Click here to see him with his hair tied back 

The leader of a gang that was formerly known as the Fallen Angels. He has gathered many gangs under his banner, forming them into a single empire.

  • Bishōnen: Although the effect is ruined slightly when he has his hair tied back, he is still quite pretty.
  • Demonic Possession: He was possessed by a very difficult demon when Saotome was asked to show him how to tame it. The demon's name? Lucifer.
  • The Emperor: What he styles himself as.
  • Expy: Resembles the flashback version of Sensui Shinobu. They even share a first name.
    • In his original appearance, he was wearing a school uniform that made him look almost exactly like Misogi Kumagawa, which suits his twisted personality.
  • Good Smoking, Evil Smoking: Oddly enough for a series focusing on Delinquents, nobody underage really smokes, making Ringo and Takamiya stand out.
  • Magnetic Villain: He has managed to gather a lot of different gangs under his banner. Might overlap with Dark Messiah.
  • Oh, Crap!: After Oga powers up. He tries to run.
  • Power Limiter: His training was basically turning his own body into this, so Lucifer's power didn't eat his skin away and eventually kill him. He proceeds to show Lucifer's power by giving EVERY SINGLE ONE of his mooks a King's Crest - that's 261 Lucifer Crests total.
  • Sempai Kouhai: Calls Fuji his sempai, alluding to the fact that both of them were taught by Saotome.



  • Big Bad Duumvirate: With Satan in the last story arc of the manga. Their fusion serves as Final Boss.
  • Blood Knight: He was excited to hear that Baby Beel awakened, but he's disappointed at how weak Oga's become after separating from Baby Beel.
  • Evil Cannot Comprehend Good: Himekawa tells him that his inability to comprehend the Undying Loyalty that the main cast has to Oga will be his downfall.
  • Evil Is Petty: Turns everyone without magic resistance in Ishiyama to stone because he was annoyed at how loud they were.
  • Giant Space Flea from Nowhere: He was mentioned by name here and there leading up to the final arc, but never actually made any kind of appearance until the final showdown.
  • Hikikomori: He claims that he doesn't have the courage to talk to other people so he spends most of his time in his room.
  • No-Sell: Completely unfazed by Nasubi, Takamiya, and Akahoshi's attacks.
  • Punched Across the Room: Sends Oga through several houses with a single punch.
  • Sempai Kouhai: Calls Takamiya his kouhai, alluding to the fact that both of them were taught by Saotome.
  • The Dreaded: Shaping up to be this. The fact that Solomon company is banking on him "putting everything in order" doesn't give our heroes any relief. Takamiya evens calls him a monster.
  • World's Strongest Man: Not really, but he has the reputation of being "Ishiyama's Strongest Freshman of All Time".
  • Worthy Opponent: Seems to think of Baby Beel as this.

Takamiya's Empire

The various gangs and gang leaders that have been gathered under Takamiya's lead.



A man working with the Upstarts who seems to be the Bigger Bad of the arc.
  • Bigger Bad: He claims to Furuichi to have gotten most of the group their spellcasting abilities. It may or may not be true, since Takamiya seems to have gotten Lucifer another way.
  • Malevolent Masked Man: he wears a domino masquerade mask.
  • Mission Control: He did not get involved in any fighting until chapter 217, preferring to confer with Himekawa on plans.
  • Mr. Exposition/Just Between You and Me: He explains things to the Ishiyama students, such as the power nullifier, Takamiya's power levels, and so on.
    • Himekawa uses this against him once Udagawa comments that Beel and Oga have built up enough power to take out Takmiya.
  • Nice Hat: A top hat.
  • Oh, Crap!: When he realizes Himekawa was playing him the whole time.
  • Sharp-Dressed Man: Suit, top hat, long coat, and cane. At a high school for delinquents.


A very, very posh school, where the kids of Ishiyama High are forced to go after Oga accidentally destroys the entire school. As it's a high-end academy, a lot of the kids there definitely don't approve of the delinquents. Much trouble ensues.

    Academy as a whole 


Kazuya Yamamura

Voiced by: Shintaro Asanuma

A student at St. Ishiyama who idolizes delinquents, especially Oga.

  • Fanboy: He loves delinquents, and can go into exhaustive detail on what makes any of the Ishiyama delinquents awesome.
  • Japanese Delinquents: Desperately wants to be one.
  • Non-Action Guy: Even moreso than Furuichi.
  • Ship Tease: With Azusa. Not only are they seen together all the time, but they form a pair during the Saint X'mas contest.
  • Those Two Guys: A mixed guy/girl version with Azusa as two Saint Ishiyama students hanging around with the delinquents.


Azusa Fujisaki

Voiced by: Yoko Hikasa
A student at St. Ishiyama who spends most of her time with Kazuya. Also a complete airhead.
  • The Ditz: Got disqualified during charades for just blurting out the answer.
  • Girlish Pigtails: More childish than some of the actual children.
  • Horrible Judge of Character: She thinks all of the delinquents are nice, friendly people. Sure, they are deep down, but she thinks they're this on the surface.
  • Ship Tease: With Kazuya. Not only are they seen together all the time, but they form a pair during the Saint X'mas contest. Furuichi even told them to "Just start dating already!"
  • Those Two Guys: A mixed guy/girl version with Kazuya as two Saint Ishiyama students hanging around with the delinquents.

The Six Knights

Saint Ishiyama's resident Absurdly Powerful Student Council. A group of student club captains who act as enforcers for school protocol, they more or less have carte blanche to do whatever they please to maintain order.


Hisaya Miki

Voiced by: Nobuhiko Okamoto

An old friend of Oga and Furuichi, who moved away when they were kids. Has a serious grudge against Oga due to the events of his last day in town. Practices the Izuma style of martial arts, mixed with a few other styles.

  • Ambiguously Gay: Asks Oga if they can walk home together while blushing. Much later, after hearing Nene talk of how enviable Oga and Furuichi's friendship is, he has quite the strained expression on his face.
  • A Beating in the Limelight: Makes an appearance after a long period of absence during the Demon Tissues arc only to be curb-stomped by Furuichi to show off the power of the tissues.
  • Arrogant Kung-Fu Guy: Attempted to use some of the techniques he learned from Izuma against Oga; some of which he wasn't ready to use yet.
  • Beauty Mark: He has two, one under each outer eye corner.
  • Curb-Stomp Battle: Was on the receiving end of one against a Demon Tissue enhanced Furuichi.
  • Forgotten Childhood Friend: Miki appears this at first to Oga. It's later revealed that it was part of a surprisingly intelligent move by Oga to protect Miki from a thug the two ran across that was moving to the same location that Miki was by publicly denouncing Miki and sparing him any Revenge by Proxy.
  • Good Scars, Evil Scars: Has a claw mark on his face from where a delinquent brutally scratched him when he was a kid.
  • Homoerotic Subtext: He's obsessed with Oga and far too clingy for the latter's comfort.
  • Jerkass
  • The Lancer: He seems to be Izuma's protege and the one he trusts the most when it comes to conflicts.
  • Out of Focus: Affected Miki the most amongst the Saint Ishiyama cast. Despite having an engaging backstory with the main cast's Oga and Furuichi, he has strangely been non-existent ever since him and Oga patched things up at the end of the volleyball match. Nanami Shizuka, and to a lesser extent, Kaname Izuma, have more screen time than him.
  • Three Man Band: Him, Oga and Furuichi during their childhood.
  • Took a Level in Badass: Once a regular weakling with aspirations for greatness. After a certain altercation in the past dedicated himself to becoming one.


Ichirō "Alex Rodriguez" Shinjō

Voiced by: Daisuke Hirakawa

The first of the Six Knights to fight the delinquents, and the boxing expert.


Mitsuteru Sakaki

Voiced by: Keiichi Nakagawa

The sword-wielding member of the Six Knights, who rarely speaks.


Hiromichi Go

Voiced by: Takahashi Shinya

One of the most dangerous of the Six Knights, he practices a style that is noted to require both intelligence and strength.


Shizuka Nanami

Voiced by: Haruna Ikezawa

The only female of the Six Knights, and generally referred to as "Lady Shizuka."


Kaname Izuma

Voiced by: Kenji Fukuda

The student council president of St. Ishiyama and master of his family's hereditary martial arts school.

  • Affably Evil: Seems to be a good-natured fellow and doesn't enjoy fighting... Death matches, however, are apparently a different story.
  • Badass Bookworm: An intelligent, methodical schemer who can punch people through walls.
  • The Dreaded: To the entire academy. "Now that he's here...we don't have a chance. Of course, that goes for Oga too..."
  • Genius Bruiser: One of the taller and largest human characters in the series, also seems to know much more then anyone else what is going on.
  • Half-Human Hybrid: It's not clear how far back, but he's got enough demon blood that any normal human is instinctively terrified of him.
  • Martial Arts and Crafts: During the ULTIMATE volleyball match, he uses one of his family's finishing moves to serve.
  • Passing the Torch: Later hands over the reins of the Student Council Presidency to Shinjo for his final year.
  • Red Herring: Seemed poised to be a dangerous new Big Bad but it never came about.
  • Scary Shiny Glasses: The surest sign that he's using his demon powers.
  • Student Council President: Unlike Oga, he's actually the president. Though he resigns following the volleyball match.
  • Triang Relations: A type 4 or 5; he apparently has some feelings toward Shizuka but she wants Tojo, so he spends most of his time in the Christmas arc trying to be the Moment Killer.

St. Ishiyama's Teachers


Zenjūrō Saotome

Voiced by: Shinshu Fuji

The second teacher the delinquents get at St. Ishiyama, but always intended to be their permanent teacher. He knew Tojo a long time ago. He's also old friends with the principal and Aoi's grandfather.

  • Badass Teacher: He's one of the few who can control the delinquents, mostly out of pure strength. Even accounting for demons, he's still one of the strongest characters in the setting.
  • Big Brother Mentor: To Tojo, slowly becoming this to Oga.
  • Curb-Stomp Battle: Every single fight he's gotten into so far.
  • Dirty Old Man
  • Establishing Character Moment: He bursts into the manga by jumping out of a window onto the roof of St. Ishiyama and then defeating three of the most Badass characters in the series (Oga, Izuma, and Tojo) simultaneously in one panel.
    • In the anime, he beats all three with one punch.
  • Expy: Looks a lot like Jecht, with a little bit of Onizuka.
  • Jerkass
  • Lovable Sex Maniac: One of the first things he does is grope Hilda's breast, which he later describes as "world-changing."
  • One-Man Army: We haven't actually seen this, but everything points to it. Jabberwock calls him "The champ of the great war" and Behemoth goes out of his way to ensure he stays out of the upcoming conflict because "our side will take major damages."
  • Perma-Stubble: As an adult; he appears to have been clean-shaven as a teen.
  • Power Tattoo: He has the Zebul emblem on his right shoulder, which inspired Tojo's similar tattoo.
  • Wild Hair: Which he's had since he was young.


Takumi Sadohara

The first teacher assigned to the delinquents at St. Ishiyama. He was not informed ahead of time that it would be temporary.

  • Butt-Monkey: He thought he was going to be the Badass Teacher, but the poor guy got assigned to the wrong class.
  • Temporary Substitute: Technically he was introduced first, but since Mr. Saotome wouldn't be in town at the start of the year, they gave the job of teaching the Ishiyama High kids to Sadohara. But no one told him that he was just the temp until Saotome returned.
  • Wrong Genre Savvy: He assumed that if he could assert his authority, the kids would fall into line. As Saotome showed, he was actually just takes a lot more power than he has to do that.

    Principal Isurugi 

Genma Isurugi

Principal and founder of St. Ishiyama Academy.
