After spending over half his life in prison, ex-hitman Kunihiro is determined to go straight. But the shortcomings of the new gangs mean that he is soon having to call on his old-school yakuza talents. And when he falls for Asako, a beautiful piano player, she unknowingly ignites a fire within Kuni that will immolate everything and everybody around him. Regarded by many as his masterpiece, Onibi has all the hallmarks of a Mochizuki film, with the gangster elements tightly compressed and controlled to allow space in which a subdued romance can bloom. Coming from a background in porno cinema, this master of sexual relations injects a fresh passion and tension into the macho world of the yakuza film.

Small-time con man Jiro makes his living tricking small businesses out of large sums of money. In the process he acquires a helpmate Kumiko, a refugee from her stepfather's sexual abuse. But things start to get out of control when yakuza boss Kamewada muscles in on the action.
