Plot
Set at St. President Academy, an elite and extraordinarily wealthy school, the story centers on the Yūkan Club, a group of six affluent and highly capable students who take on dangerous problems to relieve their boredom. The members include Shōchikubai Miroku, a well-connected brawler with a passion for motorcycles; Kikumasamune Seishirō, the brilliant and formidable heir to a major hospital; Bidō Granmarie, the flirtatious son of a Swedish ambassador; Kenbishi Yūri, the gluttonous but strong-willed daughter of a global business leader; Hakushika Noriko, a violent man-hater from a distinguished artistic family; and Kizakura Karen, who aspires to marry into wealth. Revered by their peers, the Yūkan Club tackles kidnappings, conspiracies, criminal plots, and other extreme situations that threaten their classmates or school, treating each case as both an adventure and a way to pass time.
