Touka Minamori

A sweet and shy college age girl, she just wants to make friends. Because Kokoha broke her hymen while harassing her as a child she can use dildos without worry since it's already too late to protect her virginity. She daydreams about being raped by a nameless, faceless, imaginary older brother. Because of her masochistic nature she's forced to collect S Energy for Kokoha by doing embarrassing things.

After she's arrested twice for public nudity, Tear Heart comes to her rescue and explains that she's under her care. This means police leave her alone allowing her to wander aimlessly through town completely nude or wearing whatever fetish clothes she desires. Getting stares and lewd comments from strangers will still happen of course.
