The Fetist 1998

Slightly strange Sato entry from 1998 revisting the gay pinku (a broad cinematic term used to categorize a wide variety of Japanese films with adult content) once again. A young man in a somewhat abusive gay relationship slowly loses his mind and becomes a serial killer, slashing random people in the streets. There's a next-door neighbour obsessed with capturing sounds and eavesdropping, another neighbour who has an S&M relationship with a girl that seems to unsettle and trigger violent and confusing thoughts in the young man, and there's a gay painter who becomes obsesed with the young man. Violence escalates and becomes chaotic, but none of their behaviour makes any sense.
