Ryuki has made a full recovery, and now its finally time to check out of the hospital; however, hes desperate not to leave! The head nurse, Rumi, has a penchant for tying down the other nurses and torturing them while masturbating. Nurse Nozomi needs to have sex constantly, with anyone or anything. Nurses Sarina and Rinka have even stranger desires. Ryukis not going anywhere until hes gone through the whole nursing staff, and the hospital director Himiko, too!
