Yuuji Kazami is a transfer student who has just been admitted to Mihama Academy. He wishes to live an ordinary high school life, but this dream may not come true anytime soon, as Mihama Academy is quite the opposite. Comprising only the principal and five other students, all of whom are girls, Yuuji becomes acquainted with each of them, discovering more about their personalities as socialization is inevitable. Slowly, he begins to learn the truth behind the small group of students occupying the academy—they each have their own share of traumatic experiences tucked away from the world. Mihama Academy serves as a home for these girls; they are the "fruit" that fell from their trees and have begun to decay. It is up to Yuuji to become the catalyst to save them from themselves, but how can he save others when he cannot even save himself?
