[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 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.

With these powers, humanity rose from the depths, waging war against the shadows.Yet beneath the surface of their heroic deeds lay a hidden rot. Corruption seeped into their ranks, and arrogance clouded their judgment. As their powers grew, so did the whispers of betrayal. The true battle may not be against the creatures lurking in the shadows—but against the darkness festering within their own hearts.A question lingers: When heroes fall, who will rise to take their place?
