Eiji is a priest at a catholic school for young nurses. Well, he's not really a priest -- while traveling in Europe, he learned how easy it was to impersonate the clergy and what fun it could be. Ever since those days, he's enjoyed the unique life in the Church, even after returning to Japan. When a panty thief helps himself to the underwear in the girls’ dorm at a school for young nurses-in-training, Maria asks him to help put a stop to it by moving into the dorm himself. Although he tries to be the best person he can be, the thought of living alongside all those young nurses-in-training is enough to really get his juices flowing.
