My Overpowered Demon System

Maxwell, the greatest kick-boxer in history who held the championship for 4 years straight from the tender age of 19.

But even all that was not enough to stop a bullet.

Shot in the head during a competition, Maxwell is reborn as Azrael, in a world where power defined everything.

But he is not alone, born into one of the strongest clans in the universe, and with a quirky system, he will rise to the top again.
