"Why no one remembers the true world...!" The era when a great race of five tribes fought for hegemony on earth ended with the victory of humanity led by the hero Sid. However, this world suddenly "corresponded" in front of the boy Kai. In the rewritten world, Kai saw a scene where people lost five tribal wars due to the absence of the hero Sida? Here dragons and demons dominate the earth, and Kai-this is a forgotten existence from all human beings. However, having met the mysterious girl Rinne, Kai decides to break this rewritten fate. In a world without heroes, he inherits the hero's sword and martial art and challenges the powerful enemy races that rule.
