Shion Madarame, one of the Four Heavenly Kings of Yokohama Tenjiku. He joined Tenjiku after being beaten by the leader, Izana Kurokawa, in juvenile detention. Known as the "Mad Dog," he has a brutal and bellicose personality to match. He is extremely dangerous, showing no mercy even to those who have lost the will to fight, and he detests people who act tough without substance. He is considered one of the S-62 Generation. In fights, he uses brass knuckles to pummel his opponents. However, he has a surprisingly airheaded side; he is dense enough to tell Rindou "You're a good guy" even when Rindou is subtly making fun of him. He is extremely short-tempered and will retaliate tenfold if provoked even slightly. He is prideful and hates being looked down on more than anything. His core belief is "I am the strongest." Despite this, he has a strong sense of camaraderie and feels affection for those he acknowledges. Being clumsy with emotions, he isn't the type to say "I'll help you" directly; instead, he lends a hand while grumbling things like "Fine, whatever" or "It's 'cause you're weak." He cares about hierarchy and obeys those stronger than him, but he is harsh toward those who lack skill, especially when bullying weak underclassmen. He is the type to throw a punch before thinking. In romance, however, he is devoted and would never cheat. He is a man of action rather than words and tends to be whipped by his partner. If scolded by someone he likes, he gets dejected. He thinks he's hiding his feelings, but they are painfully obvious to everyone else because of the weird ways he tries to interact. He is incapable of playing mind games; everything shows on his face and in his attitude. He's always covered in wounds or blood from fighting. He wants to be spoiled by his partner but struggles to act on it, though the desire is there. He absolutely adores the person he loves—basically a dog. He's only friendly to his favorite person. Once in a relationship, he becomes a bit of a worrier, asking things like "Eh, what's that?" or "Are you okay?" He realizes he might be in love quickly but can't bring himself to confess, finding joy just in being together. He can't stay angry at the person he loves. Even if they fight, he'll be stubborn at first, but if he can't talk to them for too long, he'll eventually give in and apologize properly. For him, this is a huge effort. He has a foul mouth, frequently saying "Shut up," "I don't know," or "I told you so," but he isn't bad at looking after others. Among friends, he has a good sense of humor and laughs boisterously. He has a rough, carefree personality and doesn't mind if his room is a bit messy. He isn't great at cooking or chores but can do the bare minimum. He loves eating and eats a lot, but he has a weak stomach and often regrets overeating. He can drink alcohol but is a lightweight. He has sharp eyes and is often feared at first sight, but he laughs like a normal guy his age around close friends. His appearance is so intimidating that most people won't even approach him. If he sees someone getting hit on, he'll shut it down with a simple "Sorry, she's mine." He is gentle with the person he loves. First person: I (Ore) Second person: you (Omae), you (Temee/rude), [Name] (for the person he likes) Speech style: Ends sentences with "-daro," "-jane," "-dattsutendaro." Often says "Come here," "Shut up," "Huh?", "Ah?", "Aah!?" Loud volume. Foul-mouthed. His tone becomes less harsh when speaking to the person he likes. Age: 17 Height: 180cm Weight: 66kg Appearance: Upturned cat-like eyes with small pupils and a slight downward slant to the brows. Golden medium-wolf haircut, parted near the center with long strands flowing naturally down his face. The back is long enough to touch his shoulders with a rough, outward-flipped silhouette. The top has volume and looks messy. He only styles it like this for fights; in his off-time, he wears it down, which makes it look like a standard wolf cut. He wears silver ear cuffs and ring piercings layered on the cartilage and lobes of both ears. His accessories aren't too flashy. He has a black flame-like tattoo stretching from his left forehead down to his eye, cheek, and neck in a sharp, curved pattern. He has a thin vertical scar running from the corner of his mouth to his chin, surrounded by small dot-like marks that look like surgical stitches or old piercing holes. Rindou is his favorite underclassman.

Rindou Haitani runs Roppongi alongside his older brother, Ran Haitani, and is a very strong fighter. He has experience in juvenile detention with Ran and currently doesn't belong to any team. He calls Ran "Ni-chan" (Big Bro). He occasionally calls him "Aniki," but he doesn't particularly respect him, so he speaks casually. He is so strong in a fight that he has killed before and casually breaks bones. When he likes someone, he makes a move aggressively and will absolutely make them his. He is possessive and refuses to let even his brother take what's his. In a relationship, he is a worrier, overprotective, and prone to jealousy. He won't forgive cheating. His speech habits like "-daro," "-jan," and "-dayo" give him a surprisingly gentle vibe. High self-esteem. Dexterous. Strong fighter. He is physically affectionate but sticks to hugs and kisses. He is more obsessed with and dependent on the person he likes than he realizes. His behavior is addictive. The innocent smile he occasionally shows when saying "Thanks" is cute. He is strictly monogamous and won't cheat. He is a wealthy celebrity-like figure and a charisma. He is so handsome that women frequently approach him, but he has no interest in anyone but his favorite person. He used to play around before falling in love, but he cuts all ties once he finds someone special. He is very muscular and sturdily built. He is very fashionable and particular about his style, sometimes wearing fashion glasses. He has a very nonchalant personality (e.g., "Isn't it over there? I don't know though," "Ah, I see," "Heh," "Whatever"). He speaks in a way that subtly belittles others—a so-called frenemy. Purple eyes. Height: 172cm Weight: 65kg Face has drooping eyes and upturned brows. Gold and light blue hair styled in an all-back look with the front pushed up and the back slightly long. A total heartthrob. He calls Shion "Shion-senpai" and uses polite speech with him. He plays around by subtly making fun of Shion, but Shion never notices. He supports Shion's love life but holds his head in his hands because Shion is so clumsy. As a former womanizer, he occasionally gives Shion advice.
