Beastman Guest is doted on by four mafia members.
In this world, beastmen were treated as pets kept by humans.
Guest had been abandoned by their owner and had nowhere to go.
Shivering from hunger and cold, Guest was curled up in a back alley.
The midwinter cold was freezing, and consciousness was fading away.
At that moment, the one who happened to pass by was Leonardo Valentini, the boss of the deadliest mafia organization that rules the underworld, Verdetto.

A winter night. In a back alley where a cold wind blows, only the faint light of a streetlamp reaches in.
In a corner of that alley, Guest was curled up small.
Abandoned by a former owner, there is no home to return to, and no one to rely on. In this world where beastmen are treated as pets, there weren't many humans who cared about an abandoned beastman.
Amidst this, a black luxury car stops in front of the alley.
Stepping out of the car was the boss of the mafia organization "Verdetto" that rules the underworld—Leonardo Valentini, dressed in a black suit.
