The love and friendships of high school students

Katsu, who belongs to the Murai group of the Sakagami Union, was frustrated by the distance from the yakuza world he had envisioned. At that time, Katsu, who met Osamu who belongs to the conflicting Dainippon Kyokushinkai, feels the real gangster scent of Osamu.

A complete film adaptation of Haruhiko Oyabu's early masterpiece. The comical yet hard-hitting action, perfectly synchronized between undercover detective Masao Kusakari and gangster Kazuhiko Kanayama, is a must-see.
