Kazuya Taguchi

A 13-year-old girl, just beginning to realize her own sexuality, comes home one day and finds her mother having sex with a stranger. Horrified, she runs away from home and heads towards her aunt's house in the country, only to be sexually assaulted along the way by a brutish local man. When she arrives at her aunt's house, she discovers that her aunt and cousin are not quite what she thought they were.

A brother and sister live as outcasts from their hamlet due to a belief that mental illness runs in their family. A group of villagers plot to steal their property by beating and hanging the brother and gang-raping the sister. Believing the brother to be dead, scheming to kill the sister, and making both deaths look like accidents... unbeknownst to them, the brother survives and proceeds on a mission to slaughter those responsible in the hamlet.

Pinku from 1968.
