Everyone calls Code Weber the weakest sorcerer alive-a 9th-tier trash who can't protect himself.

He's broke, greedy, and would go as far as selling his kidney for a 4% cut on a demon hunt.

Until he finds out...

He's a Zero.

An human possessed by a demon. And the only way he gets stronger is by defeating demons and stealing their powers.

Now, with a 1st-tier mentor, crazy guild members, and a voice whispering within him, Code has new goals:

Get rich.
Get strong.
And if the world drowns into oblivion along the way?
Well, 4% of the ashes is still profit.

Follow the story of a no-hero, zero-morals, bloody climb to the top, where the weakest sorcerer becomes the strongest monster.
