2083 AD. Akizuki High’s Superpower Club accomplishes their first victory and dominated the nationwide competition. However, the joy was only momentary. Due to a violent incident involving members of the Superpower Club right after the tournament, they were punished by getting their win revoked and banned from conducting club abilities for two years.
From then on, two years pass. Upon receiving the previously sealed-away key to the Superpower Club’s room, the club’s captain, Kanzaki Azuma, is given a heartless ultimatum by the school’s principal.
At the same time, a transfer student arrives. The second-year girl’s name was Sendou Futaba. Unexpectedly, Futaba’s mother is a member of the U.N.-supervised “R8″; a group whose members are composed of the strongest superpowered people. Azuma, seeing her as the last resort for the club’s continuation, headed towards her classroom… without knowing how much she really hates superpower clubs.
