Summary

He filed 101 support tickets. The System turned him into a demon.

Kairon is a system clerk that finally gets his own city charter. So he does what any good bureaucrat would. He reads the entire Terms of Service, identifies a loophole, and exploits it.

Unfortunately doing so ended up calling down a pillar of hellfire that roasts him, all his villagers, and everything else within a league alive.

Now he's a demon that's got ten confused imps, a tower with a giant floating eyeball, and a rudimentary system that raises buildings through rends in reality.

A MC that wins through competence, scheming, and middle management:

Anti-hero MC

Dual progression system: LitRPG & demonic power. One on the surface, one beneath.

4X Elements: City rings, demonic rituals, spawning grounds, and buildings torn through from another plane.

A theocratic empire that will never stop hunting him.

No Hero. No harem. No saving the world. Instead, a ruthless clerk that neither the demonic plane nor the church saw coming.

The start of the hit litrpg series with over 350,000 views on Royal Road!

Tropes Include: Anti-Hero Lead, Monster Evolution, System Exploits, Kingdom Building, Non-Human MC
