Tsuzumi Haruto

Haruto attends school with his younger sister Yuka and childhood friend Toua. He learned hypnotism to help his sister with her illness. He decides to test it out by getting Toua to show her breasts to him at school. She wakes up from the hypnotism and realizes what he's doing and gets very mad at him. Later, although she's still angry, she doesn't remember anything that happened and can't remember why she's angry.

How will he use his new found power?
