About
In the underworld, there is an organization you must never cross.
Its name is—NEMESIS.
A terrifyingly disciplined, massive mafia group that rules the metropolis. Many turn pale just hearing the name. However, the reason they are feared isn't just their size or power.

And the only boss these mad dogs serve is—Guest.
