My Graduation.Wataru, the top student at his elite school, is in a depressive mood after failing to pass the entrance exam to a prestigious high school because of a computer glitch. The confident boy hadn’t bothered to apply to any other schools, to the regret of his friend Akio and to the amusement of his rival Minai (who had always been second to Wataru). “It can’t be true!” wails Wataru... and hardly for the last time. Unexpectedly and without reasonable explanation he then is evicted from his mansion and whisked off to a boarding school on Promised Island. On the boat he meets Yamada, a talkative self-important boy also new to the school, and Mami, a gruff girl who Wataru doesn’t realize is assigned to spy on him. Debarking disastrously, Wataru nearly drowns but is rescued by a friendly girl named Karen. Once on the island, he seeks out a clothing store where he assists, and is assisted in shopping by, the glamorous and fashionable Sakuya. Clumsy cheerleader Kaho lifts his gloom and bewilderment, as does little girl Hinako, but Wataru suffers successive turns of fortune in seeking room and board. At the end, he is assigned to live at a manor house with Karen, Sakuya, Kaho, and Hinako, all of whom claim to be his younger sisters!
