はっぴぃふぁくとりー

Nanahouka Gakuen was built as a test facility to solve problems with the escalator system that is a commonplace. Yuu’s normal school life turns upside down when the school board chairman declares that there isn’t enough happiness in the school and forms the Happy Factory Club (HFC). He is forced into the club so that he can enjoy a happy adolescence.
