Azumabashi

吾妻橋

Azumabashi leads a rival school gang called the Four Great Ones of Sumida. This heavily scarred thug confronts Kyouichi Houraiji during class in the introductory episode, after which the Great Ones are thoroughly beaten and humiliated by Kyouichi and Tatsuma Hiyuu. From that point on, Azumabashi addresses Kyouichi as "Aniki" (a gangster term for big brother) and consistently assists the Magami five, typically serving as a chauffeur on his motorcycle or delivery van. He is a kind person and serves as typical comic relief.
