Extremely Crushed (2014)

Synopsis

Bando, leader of the Bando-gumi (Hideo Nakano), is approached by a seemingly ordinary civilian, Keisuke Katagiri (Riki Takeuchi). Katagiri impresses Bando by quickly selling a large batch of drugs under their control, earning his trust. But this is only the beginning— Katagiri is secretly on a path of revenge for his elder brother Asahi (Masakatsu Funaki), who was assassinated by Bando. Before long, Katagiri becomes known in the underworld as a “Gokutsubushi” — a man who doesn’t just kill a boss… he wipes out entire syndicates from existence.
