On the verge of his entrance exams, Kyohei decides to attend a local Comiket for some relaxation. Coincidentally, he discovers it's being held near the home of his mother's older sister, Mari. His mother asks Mari to let Kyohei stay at her place for about a week. When Kyohei meets Mari on arrival, he can't hide his shock—she bears an uncanny resemblance to a character from his favorite anime, "Majinshin Lady Romano." From that moment on, Kyohei finds himself thinking about Mari more and more. Deep down, he senses something beginning to stir inside him.
