Welcome to Irabu's Office
Many patients with different problems visit the psychiatric ward of Irabu General Hospital; a trapeze artist suffering from insomnia after suddenly failing his jumps, a gangster afraid of knives and sharp objects and a business man who has an erection 24 hours a day. They undergo counseling by Dr. Ichiro Irabu, who is the child-like son of the hospital director. His assistant is the sullen faced sexy nurse Mayumi. With his mysterious injections, and advice that does not make sense, Dr. Irabu confuses his patients. But at the end of his unique treatments, the patients are led to digging further into their souls to find peace of mind.
