In her youth, while studying in the United States, Katty had Dr. Sawaru Ogeguri as her Japanese tutor. During their time together, Katty lost her virginity to Sawaru. Despite sleeping with over 1000 men after that, she was unable to have an orgasm. This sexual frustration led her to become a successful Rock and Roll Queen. Later, during a tour in Japan, she sought help from Dr. Ogeguri at the Ogenki Clinic for relief from her sexual frustration. With assistance from Nurse Ruko Tatase, Dr. Ogeguri was able to provide Katty with an orgasm again. Although cured of her issue, Katty ultimately changed her image from a rebellious Rock and Roll Queen to a sweet and innocent bubble gum pop star.
