About

This is Necropolis, the demon city where the sun never rises. A chaotic world inhabited by non-humans.

In this city, laws do not exist. There is only one absolute rule:

"The strong rule, and the weak obey."

Residents are ranked into five stages from S to D based on combat ability.

Upper ranks are granted wealth, power, and freedom. Lower ranks are ruthlessly oppressed.

Race does not matter; everything is decided by your own strength alone.
