St. President school is one of the most prestigious schools around. Everybody in this school respects the Yuukan club, the richest and most popular group. Its members - Bidou Granmarnier, Shouchikubai Miroku, Kenbishi Yuuri, Kikumasamune Seishirou, Hakushika Noriko and Kizakura Karen - go through dangerous adventures to save their schoolmates and, of course, to kill time.
