Ryuki has fully recovered, and it's finally time to leave the hospital. However, he does not succeed. The older nurse, Rumi, has a tendency to tie up the other nurses and torment them by masturbating. Nurse Nozomi has a great need to have sex all the time, no matter with whom or with what. Nurses Sarina and Rinka have even weirder desires, as we will truly witness! The warmth of the nurses' touch haunts Ryuki, not giving him a moment's peace, but he is not allowed to leave the hospital until he "passes" through the entire medical staff, and the hospital director, Himiko, too.
