ミズチ

A demon girl and Ryuuga's most loyal servant. She restores Ryuuga's memories through sex in order to share her power with him. She doesn't care much for human morality. She is able to offer Ryuuga advice on where girls are likely to be hiding and runs the hint corner when you get a game over.

She is able to create most objects as Ryuuga needs them such as machine guns for Haruo and his gang, collars and chains, sexual items such as vibrators and super concentrated aphrodisiacs and other such things. She also has the ability to transform herself into Ryuuga's scythe in order for him to harvest souls of the girls he's broken.
