Masashi Hirakubo

A would-be bank robber forgets his mask on his first big heist, and then botches an attempt to shoplift a replacement mask from a nearby convenience store. The store's clerk, a washed-up rock star, chases the thief and literally runs into a Yakuza to whom he owes money. Thus begins an all-night, three-way pursuit through the streets of Tokyo.

A dangerous lunatic going around breaking into the apartments of various women and brutally raping and killing them while wearing a black outfit and black bondage mask. One night he breaks into the apartment of a care worker and rapes her. He doesn't kill her though as he finds that he falls in love with her. So instead,he returns on different nights and rapes her time and time again...pretty rough life for her considering she was gang-raped when she was a schoolgirl (shown in flashbacks). She falls in love with the detective investigating the case,but the rapist is still on the loose.

One morning, Haruki comes to school wearing goggles. His classmates make fun of him as usual, but the goggles are meant to hide the bruises from the abuse he received from his father.
