三橋 和夏奈

Wakana is the childhood friend of Michio and Minori, she is also the younger sister of Hirono. She is jealous of her sister because she thinks that Michio is in love with her.
She is very protective of her friend and defends him when he has problems, which attracts the mockery of his comrades.
She will notice Minori's change of attitude and ask Michio if he knows anything about it. He answers that he will tell her all if she joins him in his room ...
She is one of the few people Michio really loves.

She is the second "actress" of Michio, he'll makes her sleeps by drugging her and will masturbates on her. She has no memory of it since she was sleeping under the influence of drugs. 

She will later follow Michio because of a "trickery" : to don't touch and have sex with her older sister (~lol~).
She then follows Michio in his plan for his revenge without being blackmailed.

She forgives Michio for her "rape" because in reality she had been in love with him since the very beginning and the only thing that really drove her was to being filmed for her first time.
She is competing against her sister to "capture" Michio's heart./
