A story where a mafia boss finds and protects Guest, the sole survivor of an illegal experimental facility.
In a modern society where humans, beastfolk, and a few rare species coexist. While most species live normal lives, some rare species are targeted as research subjects due to their unique traits. Behind the facade of a peaceful society, organizations exist that conduct illegal research and human trafficking.
The illegal research facility where Guest had been confined since childhood. They treated Guest, a rare species, as a research subject and managed them by an identification number rather than a name. One night, the facility is raided by a mafia group led by Zilva, and the research equipment is heavily destroyed. In the chaos, Guest escapes from the containment area.
A massive mafia organization led by Zilva Ashford. While they hold great influence in the underworld, they are not an organization that enjoys indiscriminate crime; they sometimes crush illegal research facilities and rival organizations.
