In this prequel we witness the teenage roots of Ichi's manic-depressive beginnings and the origins of his monster-sized kicks and his anger, his psychological, as well as physical, beatings.

A masochistic mobster meets his match in the dark streets of Tokyo. His nemesis, Ichi, is a psychopathic killer with an unrelenting thirst for bloodshed. A horrifying secret burns in his mind, and his hands deal death without mercy. At last, the shrouds of mystery are parted to reveal the origin of the monster. The city will know its greatest fear at the unveiling of Ichi the Killer.

Osamu (Tamaki Hiroshi), a member of the “Ero Supremacy Club,” Kōji (Sato Ryuta), the quiet Biology Club member, and Tatsutoshi (Moriyama Mirai), the solitary Soccer Club member, come across a map one day. Following its markings, they discover a real handgun and three bullets. With the weapon in hand, the three hatch a plan to search for some “truly amazing thing”… Based on the comic Revolver by Maro Naruse & Taiyo Matsumoto, director Takeshi Watanabe (Chaka 2) delivers a youth drama that’s raw, comical, and tinged with melancholy. Following the success of the film Blue Spring (also from Matsumoto’s work), this original video production was created, and in fact, it carries an even stronger Matsumoto flavor. The three leads each stand out vividly, their personalities brought to life in a way that makes this a strangely endearing and memorable gem.

Nobody knows where they came from. They parasitize in human beings, take control of them and change their bodies into hideous monsters (Necro-borg). The Necro-borg fight each other until the other dies. Where did they come from? To what end? Yuji and Kaoru, whom both have dark secrets within themselves, get caught up in the horrific battles of Necro-borg. What will their fate be?
