Mihama Academy—on the surface, a closed learning environment established to nurture students who find themselves at odds with the world around them; in actuality, an orchard-cum-prison built to preserve fruit that has fallen too far from its tree. Yet with the arrival of the institute's first male student, the nearly preposterously opaque Kazami Yuuji, the students at Mihama begin to fall out of step with their predetermined rhythms. Will Yuuji prove to be the element the girls around him needed to take hold of their lives once more, or will the weight of their pasts prove too steep a wall to overcome?

Kasugano Haruka and his sister Sora have lost both their parents in an accident, and with them all their support. They decide to move out of the city to the rural town where they once spent summers with their late grandfather. At first everything seems familiar and peaceful, but changes come as Haruka starts to remember things from his youth.

23-year-old school teacher Aoki Daisuke has a huge problem. One of his students, Kokonoe Rin, has proclaimed herself to be Daisuke-sensei's girlfriend and is now on the warpath to win him over or get him fired.

Riki was a child when his parents died, leaving him hopeless and depressed. What saved him was a group of four kids calling themselves the Little Busters. They took Riki out and played with him during his time of need. He really enjoyed being together with them, and his grief gradually faded away. Now in his second year of high school they still hang out, fight and live together, and enjoy their school life.
