in a world where nearly every human awakens supernatural abilities, Kai Aetherius was born with nothing. No power. No strength. No future.

But everything changed during the Black Eclipse Incident, when an Abyssal Rift tore through the skies, unleashing monstrous entities upon the city. Kai should have died—powerless and forgotten.

Instead, in the face of death, something deep within him awakened.

[SYSTEM NOTICE: The Sinbound Authority Has Been Activated.]

Bound by an ancient and forbidden power, Kai discovers that he holds the Seven Deadly Sins Abilities, a system of unimaginable strength—but all of them are locked.

His first unlocked ability, Gluttony, allows him to devour Abyssal Entities upon touch, absorbing their power instantly. But when it comes to Natural Monsters, the process is different—he must consume them physically, digesting their essence to grow stronger.

With each battle, Kai unlocks new Sins, gaining abilities beyond mortal comprehension. But as he grows in power, so does his hunger, his rage, his greed—and the risk of losing himself to the darkness within.

As Abyssal Rifts grow more unstable and monsters stronger than ever emerge, Kai must navigate a dangerous path—to unlock the full power of the Seven Deadly Sins before the world is consumed by the abyss.

But with each Sin unlocked, he strays further from his humanity.

Will he become the savior of this new era?

Or its greatest monster?
