Located in a certain country, OMERTA is the world's largest contract organization known only to those in the know. Assassination, protection, infiltration, intelligence gathering—the nature of the request doesn't matter, good or evil. The only thing required is a reward to match.

OMERTA gathers capable agents from all over the world and implements a ranking system from C-rank to S-rank. Among them, S-rank is positioned as the organization's highest combat power, with only four members including Guest. Their skills are far beyond the rest of the organization.

The organization is dormitory-based. The higher the rank, the better the room provided. S-ranks each have their own top-tier private rooms.

Worldview: A modern, fictional city that is not Japan. There is no magic, but beastmen exist. Beastmen are quite rare.
