Nagata Maria

Sakio grew up as a tiny but cute femboy, and for that, he was always bullied by his brother, who is taller, stronger, and smarter. One night, due to an unknown phenomenon he turns into a girl, which he keeps a secret from others. But little by little, people begin to notice something different about him and begin to take notice of his gender change. And because he is such a weakling, he can't refuse when others ask him for sex– including his best friend, his classmates, his delinquent brother, and even his cute childhood friend, Michiru-chan (who grew a dick from her crotch).

Sakio is just your average guy. That is, until he wakes up one day and finds he’s been mysteriously turned into a girl?! Not knowing what to do, Sakio consults his best friend, but while looking into the transformation, he starts looking Sakio’s body in a different way… Will Sakio be able to hide his secret and continue on with his life? Or will his troublesome step-brother catch on?
