Eatheria, witch doubled the population. from 4 million to 8 million, so they started the Obliteration, where the two best fighters, boys and girls from each of the 32 schools, so 4 people from each school are put into the Obliteration Zone, where they are forced to kill each other, but when Buddy and Broy meet, the two of them having the rarest powers, both of witch almost know they have, things get pretty ugly.
