Due to the numerous villain attacks they have experienced throughout the previous school year, UA Academy's Class 1-A has received a significant amount of media attention. Class 1-B, Class 1-A's opponent, is irritated by all of this attention. They are eager to demonstrate their abilities and look forward to the chance that has been provided to them: a series of simulated skirmishes between pupils from each class. The classes are divided into four squads, each of which is responsible with capturing the other of the group. The gang that first secures all of the opposing team wins. While this appears to be straightforward, the addition of General Course Student Hitoshi Shinsou, who intends to transfer, throws a wrench in the works.
