St. President school is one of the richest schools around. Everybody in this school respects the Yukan club, the most popular and richest group in the whole school. This includes Shouchikubai Miroku, Kenbishi Yuuri, Kikumasamune Seishirou, Hakushika Noriko and Kizakura Karen. They go through dangerous adventures to save their school and, of course, just to kill their spare time.
