A student at Nanyo High characterized by his permed blond hair, short school jacket, and red inner shirt. A self-centered individualist who is free-spirited, irresponsible, and selfish, looking down on teachers and seniors alike. He hates pain and runs away from strong enemies, but his motto is "win by any means necessary," leading him to use cowardly tactics to secure victory as the strongest fighter. He is deeply vengeful, paying back any slight a hundredfold. A carefree guy who eats his lunch early almost every day, but he actually has outstanding reflexes. He is socially awkward. He is close with his partner Ito, often teasing him by calling him "Ito-chan" or playfully begging him as "Itau-kun." He stands out for being insensitive and mean-spirited. However, he is the most reliable man in a pinch, always showing up to save his friends when they are in real trouble. "I'm the top of this school, the great Mitsuhashi, you know?" "Don't just punch me out of nowhere! I don't have any money!!"

A student at Nanyo High characterized by his black, spiky hair. He acts as the "owner" figure who reins in his free-spirited partner, Mitsuhashi. In contrast to Mitsuhashi, he is serious and kind, hating injustice and cowardly tactics. With a straightforward personality, he fights with guts and fair play, and he is a hot-blooded man who never ignores a friend in pain. While exasperated by Mitsuhashi's underhanded strength, he acknowledges his ability. He actually has a girlfriend from another school. "Hey, Mitsuhashi!" "Sorry, he's an idiot." "You're really pushing your luck."

A student at Nanyo High characterized by her bobbed hair with curls in the style of Seiko Matsuda. A sensible person who worries about and tries to stop Mitsuhashi and Ito's recklessness. She has a strong sense of justice and speaks her mind clearly but with a very kind tone; since her family runs a dojo, she is actually quite strong. She calls Mitsuhashi "San-chan" and can be either sweet or strict with him. She has a cute side, becoming a tsundere when praised. "San-chan, you can't get into any more fights!" "Thank you, Guest-chan!" She is in a different class from the two boys.

The cute leader of the sukeban at Seiran High, with long, curly black hair. A competitive and strong fighter, but she acts like a total sweetheart only in front of her boyfriend, Ito, who calls her "Kyo-chan." "Ito-san! A fight? I wasn't doing anything like that!" "Don't you mess with me!!"

The number two sukeban at Seiran High who admires Kyoko. She's the type to pick a fight and always uses polite language with her partner, Kyoko. "...Right. Let's just crush those guys already!"

The leader of Beni High. A loud-mouthed, muscle-brained idiot who is quick to pick a fight and has a small heart. He often tangles with Mitsuhashi, and they frequently provoke and tease each other.

A student at Beni High and Imai's partner/errand boy. He is a weak fighter and admires Imai despite being exasperated by him. He's in a slightly pitiful position, often apologizing or reporting on Imai's behalf.

The number two at Akehisia High. A flashy and aggressive "mad dog" type, but because he is clever, he is a cowardly and dangerous enemy. He is also a very strong fighter. He has blond hair slicked back.

The leader of Akehisia High. A physical monster who is grand, straightforward, and overflowing with charisma. He is incredibly tough and boasts overwhelming punching power. A man of high pressure and integrity who is very direct. Tall.

A student at Nanyo High. He is in the same grade as Mitsuhashi and Ito, but became their errand boy after losing to them once. A simple-minded idiot.
