The student council room at the prestigious St. President high school also serves as a clubhouse for the group of six called Yukan Club. Even among all the students with celebrity, rich and famous backgrounds, the six elite group members in the room stand out the most. They are good looking, they are rich, and they've got nothing to worry about except...they just have too much time to kill! These are the six group members: Miroku Shochikubai (Jin Akanishi), the only son of the police commissioner; Seishiro Kikumasamune (Yu Yokoyama), the smart president of the student council and the heir of a large hospital; Granmanie Bido (Junnosuke Taguchi), the handsome playboy and son of a Swedish ambassador; Noriko Hakushika (Yu Kashii), the traditional Japanese beauty whose father is a famous Japanese painter and mother is from a family of generations of tea ceremony masters; Karen Kizakura (Emi Suzuki), the attractive only daughter of a rich jewel dealer who dreams about marrying a rich guy; and last but not least, Yuri Kenbishi (Minami) who can fight like a man and eats like a man, and whose father is the CEO of one of the world's biggest business corporations.

Together as the Yukan Club, these six keep themselves busy solving all kinds of mysteries and problems with their talent, ability and family influences. This drama is based on one of the most successful comic series in the Japanese manga history, which continued for more than 20 years, and has sold 25 million copies. The long-awaited Yukan Club is finally in action with charming young stars of Japan!
