Ginî piggu 2: Chiniku no hana (1985)

A woman walking home late at night is attacked by an unknown assailant who knocks her out with chloroform. When she regains consciousness, she finds herself tied to a bed in a blood- spattered dungeon, at the mercy of a white-faced man in a samurai helmet who wants to turn her into a "flower of blood and flesh." He then proceeds to slowly dismember and disembowel her as the camera records it all.
