Nishi-kun

The yakuza have their best days behind them and are only a shadow of themselves. The old rituals seem out of date and their tattoos make them outcasts of society. The inexperienced student Ryō stumbles into their ranks by chance, and before he knows it, he becomes entangled in dark machinations. He quickly succumbs to the fascination of omnipotence fantasies and hedonistic decadence and sinks deeper and deeper into a parallel world of prostitution, blackmail and violence. However, there is one thing that Ryō has not considered in his naivety: once yakuza, always yakuza!

Living in the lawless Ishinari District in a future Japan, sisters Ami (Hina Nagimiya) and Yoshie (Hanakage Kanon) who sold their bodies to help their parents, try to earn a living performing as an idol group in the area. When their performance causes stranger Matsukata (Tak Sakaguchi) a notorious hitman, to notice their condition, the three realize their worth to each other in the fight against Aoyama Dharma (Kimono Negishi), the female boss of a notorious organ harvesting ring in the area. Realizing that even their skills are no match for her army of goons and henchmen, the two are outfitted with special homemade weaponry to their bodies and become the ultimate killers.
