How To Be A Great Demon

The world was once under siege by the Great Demons, extremely powerful beings, with some possessing abilities strong enough to wipe out entire Kingdoms. But due to the intervention of the Great Spirits, humanity managed to trap the Great Demons, ending their threath. But now two hundred years later, there exists a boy named Lance Grey. He has a strange power which is almost inhuman in nature. Some could say that he's Cursed, or a Demon in disguise. But the truth to Lance's power will make him a lot of enemies, enemies just like the Great Demons. With only his friends and this terrifying power, Lance must save the world from ruin, without losing all he cares about in the process.
