At school, Kamazaki Yuu feels as though there is a circle drawn around her, a line that no one will cross. A part of it is because her face looks mean, and another part of it is because she's rather socially awkward, but the largest part of it all is that she has earned a reputation for being really bad-tempered and violent to the people around her.
This all changes in her second year of high school.

Kume introduces "Kama-chan" to friendship and to the 5-man futsal club that meets on the school roof.

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.

Whatever the circumstances behind its establishment, Mihama Academy is at present home to five female students, all with their own reasons for "enrollment." For better or worse, each girl has established a routine obliging of her current situation; life moves at an idle, yet accommodating pace within the walls of Mihama.

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?
