[From Senpai Translations] A band formed by a group of classmates (and one kid a year older) from their high school Light Music Club: KETCHUPPERS. Now they’ve joined the ranks of the famous as their name makes it into the top charts. On stage they soothe the souls of office ladies and put hearts in the eyes of high school girls, but what about backstage? Can Hashitani (Tani) reign in his partner-in-crime Wakatabe (Waka), or will Wakatabe just run wild? Includes an exclusively drawn one-shot.
