WHEN THE apocalypse happened half a decade ago, South Korea was one of the few countries that didn't fall completely. Most people all over the world thought it was thanks to the five natural S-Class Espers who awakened on the first day of the apocalypse.
While that was true, Yosef Lee thought differently.
Our country got back on its feet quicker than other countries because we have Kwak Hakjae.
Aka the 'System's Representative.'
Kwak Hakjae got that title as the first Esper to enter and raid the first ever Gate that appeared in the world.
Yes, he did it alone.
As a reward, Kwak Hakjae received an Appraisal Skill— a skill that gave him the ability to see other people's class and level.
Aside from that, the lucky man also received an Inventory full of useful things.
One of them was the 'System's Heart.'
Apparently, the System's Heart was damaged before it reached their world.
