Histoire
One day, Naoya, the strongest high school delinquent in Kanto, missteps on the stairs of a pedestrian bridge and collides with Kana, the girl who was standing in front of him. Somehow, Kana's soul enters the body of Naoya, a fierce delinquent, while Naoya's soul enters the body of Kana, a plain-looking girl! Naoya was hoping to enjoy the feeling a girl's body, but when he finally takes off her clothes, he finds that Kana's body is covered with wounds and scars, and it bothers him so much that he couldn't do anything.
