The Demon King's Self-Redemption

Introduction 1: On how a helpless scumbag survives among dangerous girls and becomes a devil! Introduction 2: As an ordinary person, Su Yu said that he was panicked because a girl who descended from the sky told him that he would become the devil who would destroy the world in the future. This is not the point. The point is that the two childhood sweethearts who he thought were Chuunibyou and known as the emperor of another world were reborn and got into a fight!
