I've been looking for this scene for years and finally found it! In the first volume of this extremely violent manga, a sexy lady in glasses is chloroformed during a fight sequence.
She is next seen naked in a bed.
A girl wearing a ballet leotard visits a doctor. The doctor gives the girl something to drink, which causes her to pass out. Once the girl is fast asleep, the creepy doctor brings out his camcorder...

A girl is minding her own business inside a martial arts dojo. A group of young guys taser her from behind and plan to molest her. In a brutal scene that follows, another male comes and rescues her, brutally beating all the attackers.
A woman is kidnapped by a gang of thugs, aboard the back of a pickup truck. They start to take off her clothes. She's rescued though. In a later scene, the same woman is knocked out from behind, though we don't see it.
