After being abandoned by his father, Masaya ends up saving the young girl, Rise, from some assailants. Moved by his heroism, she invites him to attend her all-girls' school for a year to help make her case that the school should go co-ed to resolve its funding issues.

From there, your new life at Vincennes Private Girls' Academy begins. Over the next year you'll navigate interacting with the sheltered girls of the academy, the faculty who want to preserve the academy's strict traditions, and the cute heroines who have taken an interest in you. Will you prove that it's okay to shed some traditions and change with the times? Will you show the doubters that men can have friendly relations with women? Will you fall in love and find a true partner of your own?

Fall in love with one of the four main heroines, and enjoy plenty of tender moments, adorable scenes, and charming interactions with them all! Will you go with classic, bright heroine seeking to save the school? The childhood friend who feels a little out-of-place in this sheltered school? The cool beauty who values traditions? Or the carefree tease hiding more than meets the eye?

Enjoy a full year-long school term over the course of 26 chapters, with plenty of festivals, balls, and school events to participate in with the heroines!
