On a forbidden hospital ward, the head doctor performs madly erotic experiments, stripping the nursing staff of their uniforms, inhibitions and self-control... until even he is shocked by what he uncovers!
Sora, who was critically injured, was saved and hospitalized. He was then moved to a special ward by the beautiful director, Reika Mikage, because of his "healthy" body. After meeting her, he was asked to be a test subject for a new medicine. He has no kin, so a nurse, Yū Yagami, was put in charge. As a reward during the process, the director gave him the authority to do what he wants not just to Yū, but other members of the hospital staff.
