  Yuu Akiyama (秋山 優, Akiyama Yū) is the banchou of the Itabashi District. He was raised in the Harobaro House institute for the orphan and take care of his thirteen little apoted brothers and sisters. Lies, sneak attacks, covert weapons, kidnapping, black mail in order to support the institute on his own, he'd dirty his own hand with any crime, but now he's relying his own skill to win the 23 District Project. He wears a burglar mask and cap when he fights so others don't know what he looks like, so they don't set traps for him and also so his family won't be put in danger, he states "if it's for the sake of my precious brothers and sisters I'll be as cowardly as it takes". He's the villain of justice aiming to become dictator for the sake of his little brothers and sisters.


He is the Hikyou (Cowardly) Bancho. His catch phase is "lets fight in a fair, cowardly way" He will use anything to win (lies, sneak attacks, covert weapons, kidnapping, etc.) he attacks Akira with a seris of traps. Using a cell phone shaped pistol on a train to injure his leg, blowing up an office to temporally blind him, tricking a semi-blind Akira to jump into traffic using a ball (lying to Akira saying it was a grenade) breaking his right arm, kidnapping Tsukimi so that when he finally fights Akira, Akira has to hold still. He was defeated when he tried to use a wrecking ball on Akira and was sent back at him. Akira was ready to deliver the final blow when Yuu's underling (Kouta, one of his little brothers) intervened stopping Akira, Harito appears and uses Kouta as shield telling Yuu to stab Akira. Yuu does so then fake stabs himself trying to save Kouta in the end Akira saved both of them since the knife had no effect on him. His reason for helping Akira is so that Akira will be indebted to help him when needed and he plans to back-stab Akira when he wins control over all the districts (the real reasons is most likely that he is thankful to Akira who worried about his (Yuu's) family even if he tried to kill him).



He is a man who seemed to be a coward who doesn't fight his opponent fist to fist but rather to use dirty tricks and lies, but despite this he is a good man trying to help his little brothers and sisters by winning the 23 District Project for a better life for them and will fight as cowardly as he can be to protect someone he care about.


Yuu grew up in an orphanage with his 13 little brothers and sisters (no blood relation). After the owners lost their money to gambling debts, he would do any dirty job for money (blackmail, fraud, stealing, etc.) to support the orphanage. Some of the orphans knew about this but still cared about him like a big brother.
