Destined Villain's Life

A place abandoned by the entire parliamentary system. It was once enveloped by the intrusion of a foreign world.

Though the invasion ultimately failed, remnants of unknown species were left behind, blending in with humans. Not long after, the underground took over, giving it a name of its own—[The Pandemonium].

The name suited the chaotic nature of the place.

Paying the nervous driver his fare, Zick stepped out of the car and merged into the sparse street.

Despite its reputation, the district wasn't completely lawless. Vehicles moved steadily along the roads, and order, of a sort, existed.

Laws did exist here, but they were created by [The Pandemonium], shaping a system that benefited their growth.

'[End's Wing] was their creation as well. In this place, it's impossible to live without an account in it.'
