Prologue: Predator X and X Prey

With a flash of lightning, Saitama's entire world is turned upside down. Forced into a realm that is completely off its hinges, it appears to be the responsibility of one bald hero to deal with a world with a freakishly optimistic kid, a child assassin, a rather sketchy magician, a vengeful teen, and some weird guy who looks old...but is actually a teen? Rated T for Tatsumaki!
