Damien Julian is an 18-year-old loser, who has been bullied and mistreated his entire life, at home, he has to deal with his abusive father, and at school, he is constantly been bullied by delinquents, and to make things worse he is always looked down upon by his peers, till one day a mysterious screen appear before him as it said.

[The world has seen the lingering evil in your heart]

[Would you like to be one of the nine demon kings of this world]

[If so what are you willing to sacrifice?]

In the heat of the moment, Damien made a deal with the world, that he would give up everything he owns, or do anything it wants, and in exchange, he shall be reborn as a new Demon King, and what the world required from him as payment was.

[In exchange for power, become a slave of the world, and act as an anti-body for all eternity]

At that moment, Damien agreed, but little did Damien know, that becoming a slave to the world meant he has to be its immune system, what that entail is, that anything that threaten the world must be destroyed even if he has to wipe out humanity, to save it, or assassinate historical figures to bring fort balance or even manipulating events that can potentially end the world, to save the world, this is the story of a necessary evil, not the story of a hero who cares for others.

It was just a game, one Evan played way too much, but it was still a game in the end. At least it was supposed to be...

However, on the day the main quest ended, he discovered it was more than just a game.

The world of Aidos was real and the demon threat was even more so.

He was sent to be the leader of the new generation heroes and save the world from the demon invasion by the god who made the game.

Unfortunately, nothing was as simple as it may have seemed.

As the truth behind the invasion and the previous Seven Heroes was slowly revealed, he began to have second thoughts about his choices.

He began questioning if the demons were truly the enemies of Aidos.

Even more so, when he discovered a new truth.

That he may not actually be who he thought he was.
