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, a 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.

While the true nature of the "job" he is wont to alight to at the most haphazard of moments remains shrouded in secrecy, one thing is for certain: his encroachment upon the quiet orchard known as Mihama Academy will prove itself momentous in one way or another. And of course, one cannot discount the possibility that perhaps Yuuji himself carries the weightiest past of any of the students...
