男の娘学園っ! ～3人の男の娘達との運命の出会い、そして僕達は恋に落ちる!～

My name is Yoshimasa. I'm an ordinary student.
One day my parents moved, forcing me to attend another school.
It was a private academy. The school distinguished between three genders: boy, girl and transvestite.
I wasn't friendless for long. A classmate named Koyomi talked to me. Then I met the class president Kaoru, and Yuuki, an underclassman from PE. All of us were just discovering our sexuality!
