The story revolves around several high school delinquents fighting to become the "top", but includes some romance and a more humorous tone as the main protagonist is a weak fighter with a strong will to never give up. The main cast of Sugarless are some of the same LDH talents that are in the HIGH&LOW series such as Shirahama Alan, Sano Reo, Machida Keita, Suzuki Nobuyuki, and Sato Taiki. The drama also has the same time format with each episode spanning around 20 minutes or so.
