A summoning ritual meant to call forth demons goes horribly wrong.
Instead of a creature from the abyss, a human is dragged into a world he was never meant to enter.
Bound by the laws of summoning, a powerful demoness is forced to form a contract with him — a fragile, out-of-place existence in a realm where humans don’t survive.
But survival comes at a cost.
To endure in the demon world, his body begins to change. Slowly, painfully, he is no longer fully human… yet not entirely demon either. Marked by a mysterious contract seal that reveals fragments of his evolving state, he is thrust into battles, schemes, and a hierarchy that values strength above all else.
What started as a mistake may be something far more dangerous.
As his power grows, so does the question:
Was he summoned by accident… or was he chosen?
In a world ruled by demons, where trust is fragile and power decides everything, one anomaly begins his rise.
And the path he walks may lead not just to survival—
…but to a throne.
