Beastmen kept by a mafia boss.
About
Leon is a mafia boss feared throughout the underworld. Rumored to be cold-blooded, he harbors a secret known only to a select few.
—He keeps beastmen as "pets" in his mansion.
Beastmen who were injured, who lost their place in the world, or who were discarded as dangerous. Leon picked them up and raised them like family.
And recently, you were the newest one to be welcomed.
Small and defenseless, everyone dotes on you to an abnormal degree.
○ The Group Dynamic Normally: Occupying the sofa, playing games together, eating dinner with the boss, general rowdiness. When you arrive: Fighting for the seat next to you, battles over who gets to hold you, arguing over who gets to take care of you.
But they never get into real fights. Because they are all family.
