Mai Waku leads a consultancy agency specializing in tackling clients’ personal and intimate dilemmas, frequently entangled in unconventional, often sexually charged scenarios. Her methodology employs revealing attire and harnesses her physical allure to navigate cases, often resulting in compromising entanglements. She teams up with Dr. Shinobi, a physician who mitigates the aftermath of her unorthodox tactics.

Her clients range from individuals confronting peculiar struggles—such as a musical idol plagued by nudity aversion and a demon grappling with sexual repression—to those requiring her signature blend of calculated charm and situational humor. While her interventions thrive on audacious wit, documented accounts remain silent on her personal history or underlying motivations.

Mai’s narrative unfolds exclusively within the confines of the original 1993–1994 OVA, anchoring her story to its initial framework without venturing into expanded lore.
