Takuya works at Shiratori General Hospital, the biggest hospital in town. One day, he unexpectedly discovers a secret in his work place. The hospital is actually an underground membership whorehouse! The members consist of politicians and lawyers, who come to purchase trained sex slaves.

Once Takuya finds out about the hospital's dark secret, he's forced to help the club as a sex trainer. As he begins tormenting various girls, he realizes that he really enjoys it.... His acts of violence escalate day by day. He starts out with nurses, but soon moves on to female patients, as well. Takuya quickly begins losing his sanity. The quiet and peaceful days will never return. What awaits him beyond the doors of this dark pleasure!?
