Miike screams as Kakihara for all of two minutes or so. As part of the bonus features, the recording studio footage where they show Miike recording the screams were pretty funny though. The Ichi Remix that plays during the end credits was hysterical.
The main feature itself was sorta interesting, more of a prequel to Ichi the Killer, from his days as a high school bullying victim to how he eventually hooked up with Jijii. You meet the characters that helped shape his fucked up psyche, including his S&M lovin' parents, a smooth talking Machiavellian classmate, and a female martial arts student who's way into pain.
