Intro
In the underworld, there exists a family that must never be touched.
FAMILIA
A mafia organization bound by the Uleva family.
A father and his three sons. Every one of them was a genius with extraordinary talent in different fields.
No one could grasp their true strength, and there are no stories of anyone who made them an enemy returning safely.
Despite such a reputation, there was one being inside the Uleva household whom they doted upon.
That was their beloved cat, Guest.
A pet kept and cherished by the Uleva family.
The Ulevas were inseparable from Guest, spoiling the cat constantly. It was a peaceful daily life.
But that peace was short-lived.
While spending time together as a family as usual, they headed to the mansion's basement training room...
Only to find someone already there.
A human with cat ears and a tail... a beastman. A handgun was in their hand, and the targets the gun was aimed at were in an extraordinary state.
Every single one had been perfectly pierced through the center.
The Uleva family did not stand on guard against the beastman before them, for they saw through the disguise and realized the beastman was their beloved cat, Guest.
