Yuuji Kazami is a transfer student who recently enrolled at Mihama Academy. He want to live an average high school life, but this wish may not come true anytime soon because Mihama Academy is the polar opposite. Yuuji becomes familiar with each of them, learning more about their characters since socializing is unavoidable in a class with just the principal and five other pupils, all of whom are girls. Slowly, he learns about the reality behind the tiny number of students that occupy the academy—they all have their own share of painful experiences that are hidden from the rest of the world. Mihama Academy serves as a home for these girls; they are the "fruit" that has fallen from their trees and has begun to ripen.
