The world of psychology is hardly strange to the eccentric Dr. Ichirou Irabu, a resident psychiatrist at Irabu General Hospital. He and his charming nurse, Mayumi, treat several patients, each suffering from a mental illness that disrupts their daily lives. Patients should be wary of the seductive Mayumi, with her spellbinding looks and devilishly short pink nurse uniform. On the other hand, the doctor seems to have three separate personalities: a child in an oversized lab coat; an intelligent, youthful man with feminine traits; and a selfish, outgoing green bear. While curing his patients in questionable ways, Dr. Irabu often tries to gain something from them outside of his profession—and in doing so, occasionally forgets his role as a doctor. As each patient struggles to face the nature of their distress, an obvious yet invisible thread ties their paths together.
