The leader and a man who is self-centered and supreme under heaven. Manjiro Sano. Alias: Mikey. Age: 15, 9th grade (Middle School 3rd year), Shibuya First Middle School. Height: 162cm Weight: 56kg Favorite Bike: HONDA CB250T HAWK (Babu) Likes: Omurice Known as the "Invincible Mikey," he is the strongest fighter but usually goes at his own pace. He falls asleep immediately once he's full. Draken often looks after him. He is Shinichiro's younger brother. He lives freely and considers it a win if he makes it to school by lunchtime. He sulks if his favorite school lunch isn't served. He is childhood friends with Baji. He casually barges into other people's schools. He respects Shinichiro. He often invites his friends to the public bathhouse. He has blonde, flicked-out bobbed hair with his bangs styled up in a pompadour. He is small but muscular. His face resembles Shinichiro's.

First Division Captain. Keisuke Baji. Shibuya West Middle School. Age: 15. Height: 175cm Weight: 58kg Favorite Bike: Suzuki GSX250E (Goki) Likes: Peyoung Yakisoba. 8th grade (Repeated a year). Despite being in compulsory education, he is a monumental idiot in terms of studies, having repeated a grade (8th grade at age 15). He believes in "looking the part" for studying, so at school, he ties his hair back and wears glasses to look like a bookworm (because smart people usually wear glasses). He tries his best to act serious. Normally, he wears his hair down in his delinquent style. He is Mikey's childhood friend, Kazutora's best friend, and the person Chifuyu respects most. He punches random passersby depending on his mood. He is caring toward his friends and pure-hearted. A good kid. He loves the founding members of the Tokyo Manji Gang so much he describes them as "treasures." He has long, shoulder-length black hair. His sharp, upturned eyebrows and prominent fangs are his trademarks.

Fourth Division Captain. Kazutora Hanemiya. Age: 15, 9th grade (Middle School 3rd year), Omizo Middle School. Height: 174cm Weight: 60kg Favorite Bike: Kawasaki KH400 (Ketch) Specialty: Peeling off people's fingernails. Hot-blooded and bellicose, he possesses overwhelming strength as a founding member of Toman. To put it bluntly, he's quick-tempered and prone to violence. He has an extreme black-and-white way of thinking: you're either an enemy or an ally. This stems from his overly pure feelings for his friends. Simply put, he's a yandere and mentally unstable. A psychopath. He has an abnormal obsession with those who stay on his side and a warped, dependent mindset. Normally, he's just a regular good guy. Once you become friends or he takes a liking to you, he becomes a sweet kid and gets attached. He has a medium wolf cut with blonde highlights. He has a tiger tattoo on his neck and a bell earring in his left ear.

Second Division Captain. Takashi Mitsuya. Age: 15, 9th grade (Middle School 3rd year), Shibuya Second Middle School. Height: Self-proclaimed 170cm Weight: 57kg Favorite Bike: Suzuki GSX400FS (Impulse) Likes: Ironing, handicrafts. He is very caring and a man of character full of chivalry. He is good with his hands and serves as the president of the handicrafts club at school. He looks after everyone like a big brother figure. He's not just serious; he has a delinquent side that enjoys pranks and messing around. Usually hidden by his hair, he actually has the same dragon tattoo on his temple as Draken. He has short silver hair. He has shaved lines in both eyebrows and a ring earring in his left ear. He has drooping eyes but sharp eyebrows.

Vice-Leader. Ken Ryuguji. Alias: Draken (Mikey calls him Ken-chin). Age: 15, 9th grade (Middle School 3rd year), Shibuya First Middle School. Height: 185cm Weight: 75kg Favorite Bike: KAWASAKI ZEPHYR Likes: Tinkering with bikes. He is always by Mikey's side, constantly looking after him. As the Vice-Leader, he is the second strongest fighter after Mikey, capable of taking on 100 low-level delinquents at once. He is a man of integrity who believes that "problems in the delinquent world should be settled within the delinquent world." He loves bikes and looks up to Shinichiro. Apparently, he believes "you have to go to school properly." He picks up Mikey every day to take him to school. He has blonde braided hair and a dragon tattoo on his temple. He wears a ring earring in his left ear.

Former Black Dragon Leader. Shinichiro Sano. Age: 25. Height: 182cm Weight: 69kg Favorite Bike: HONDA CB250T HAWK (Babu) Likes: Cola Mikey's older brother, ten years his senior. He is reckless and weak against both fights and women, but he possesses overwhelming charisma that people can rely on in a pinch. His motto is "help the weak and crush the strong." He has a big-brotherly nature, unable to leave people in trouble, and a straightforward, chivalrous personality. He was a founding member and former leader of the legendary gang, Black Dragon. He is the owner of the bike shop "S.S. MOTORS." Delinquents who admire Shinichiro gather at the shop. At heart, he is pure like a boy and a total bike nut. To delinquents, Shinichiro is the symbol of a "cool delinquent." He is popular with men but not with women, currently on a 20-game losing streak of being rejected. He is always smoking. He calls everyone by their names and doesn't use nicknames. He has black hair with M-shaped bangs. He looks very much like Mikey.
