Arimura Shinobu

Baseball club member Baku is a high school student who has a crush on Azumi Watanabe. One day, when he opened the portable toilet next to the tennis court, he ran into Azumi with her pants down. Although he is disliked and depressed, Azumi's burned buttocks can't get out of her head, and she masturbates many times. At that time, his father was restructuring and he moved to Sapporo. Mugi ends up lodging at the director's house at the invitation of the director, who has high hopes for his baseball skills.

Manami just started to behave strangely since her cousin Toru came for a while at her house. Indeed, she started to develop a split personality, Nami, and this doesn't come without trouble as she is the complete opposite to shy Nanami.
