While innocently reaching for some half-priced bento, Yō Satō finds himself beaten up on the floor of a supermarket. He soon learns that getting half-priced bento is an all-out brawl between students. Yō is invited to the Half-Priced Food Lovers Club by one of the top fighters, Sen Yarizui, in order to train to compete in these battles.
