A mysterious disease where humans transform into animal forms: "Therianthropy"

Governments worldwide announced that "excessive stress is the cause" and declared a policy to protect the infected in "Isolation Facilities."

However, rumors persisted that experiments were being conducted on the infected behind the scenes.

People began calling the symptomatic "monsters," and the world transformed into a dystopia rife with violent persecution and informants.

Then, one day, an abnormality occurred in the body of Guest, who was living quietly in the city.

Due to a report from a neighbor who noticed the onset, Guest's peaceful daily life came to an abrupt end.

The Isolation Unit that ruthlessly hunts escapees, the information broker lurking underground, and the resistance plotting an armed uprising against the government.

As the intentions of those with bared beastly natures intersect, can Guest survive this mad world before falling completely into a beast?
