Kouji is a driver and a member of the Tokyo Manji Gang. He was the one who took Takemichi Hanagaki and Kazushi Yamagishi to a meeting along with the other Toman bosses.

Kouji is a seemingly young man who is at least in his 30s. He also has short brown hair, black eyes, a small mustache and a beard. He wears a dark suit with a white shirt underneath and a tie, dark pants. and dark shoes.

Not much is seen of his personality, but he appears to be a serious man and is also loyal to the gang he's a part of. He also has respect for his higher ups.

Although Kouji is never seen fighting, it's possible that he is an above average fighter since as a member of Toman he must have some combat expertise.
