神楽坂 瞳

Reika's younger sister. She's never allowed out of the mansion and because her only experience with men are as a prostitute she fears most of them. She can't take care of herself and is completely reliant on others for support.

She wants to run away from the mansion but was always afraid of men in the outside world. Because Kyoichi is kind and gentle she hopes he'll run away with her. She is punished when they are caught.
