Aratake Gang is a group of four middle school hooligans from the Seisen Middle School. The Leader is Gōki Aratake, the strongest delinquent in the whole middle school. Also, Aratake Gang got a secret base and hideout where they usually hangout and bond together.
Naoya once helped Gōki Aratake out from a tight spot, and has been worshiped by the younger as a hero. At some point he became the leader of the delinquents and was seen as a good leader in the flashbacks, and always took care of the younger delinquents. His gang used to meet at the Secret Base.
They are first seen in episode 13, Idiot, Delinquent, and Hero. The leader wants to be like his revered senpai, the former gang leader "Shiroyan". But he and his gang can’t believe "Shiroyan"—Naoya Shirokawa of the Idiot Trio—has gone soft. Aratake is unable to accept it and wants the old Naoya back, so he and his gang abducts a cross-dressing Yukimura, who they mistake for Naoya's girlfriend. They take him to their Secret Base.
