Gouki Aratake (荒嶽 剛毅, Aratake Gōki?)
Voiced by: Tetsuya Kakihara
The strongest delinquent in Seisen Middle School, he is an old friend and kohai of Shirokawa and Kurosaki. He used to be a pushover and a bit of a crybaby. He was saved द्वारा Shirokawa and Kurosaki once when he was being bullied, and immediately started looking up to them after that. Constantly seeking to become stronger, he kept his delinquent ways even after the two have graduated and retired from delinquency. He later kidnapped Yukimura, who was dressed like a girl and who he mistook as Shirokawa's girlfriend, and challenged the idiot trio to a fight elsewhere. Coincidentally, he and Aoi happen to attend the same middle school.
