THE S-CLASS HERO IS A DELINQUENT

Yujin Ichinose wakes up in the midst of a mayhem as an S-class monster launches an attack on their school. And as he triumphantly vanquishes the monster atop the school building, a mysterious orb splashes out of the monster’s remains and begins to merge inside of him. While he is preoccupied, Yujin fails to notice someone kicks him from behind, resulting in his untimely death.


However, because of the mysterious orb's ability to merge with Yujin, he is then given the opportunity to be reincarnated roughly one year before the world is taken over by top tier powerful monsters.


And as Yujin sets out to discover who is responsible for his death, he will inevitably become involved in becoming everybody’s hero saving the world as it heads for the monster’s dominion—but there's a catch: he used to be known as a delinquent boy.
