Grisaia no Kajitsu

The anime revolves around Mihama Academy, a prison-like school built to preserve fruit that has fallen too far from its tree. It is home to five female students who each have their reasons for enrolling in the academy and live their life idly within the walls of Mihama.

One day, Kazami Yuuji the institute’s first male student arrives and throws the orderly rhythm of Mihama off balance. Is Yuuji what the girls need to hold of their lives once more, or will the weight of their pasts prove too steep a wall to overcome? Or is his past even heavier than any of the others?
