At Irabu General Hospital, Dr. Ichirou Irabu is a knowledgeable psychiatrist who specializes in psychology. Together with his attractive nurse, Mayumi, he helps numerous patients cope with their mental illnesses that interfere with their daily lives. Patients should beware of Mayumi's seductive appearance in her revealing pink nurse's outfit. In contrast, the doctor displays three distinct personalities: a child wearing a large lab coat, a young, feminine man, and an outgoing green bear. Dr.Irabu often exceeds his authority and takes advantage of his patients for his own benefit while administering unusual treatment techniques. Despite the patients' different problems, there is an underlying yet essential connection that brings them together.
