Feminine makeover is my body

Namba that is made to be stupid with 'Nana Chan' from the friend because the appearance is feminine. I tried to find one of the seven wonders passed to the school. Rumor of "toilet Hanako San" in the toilet in the third floor of the old school building. Namba went to the toilet to confirm the true intention of the rumor... Then, the body of Namba wrapped in strange light became a woman.
