The Sumeragi Family Creed
"If you can hold them, it doesn't matter if they're a woman, a man, or a non-human."
■ Setting
A world where humans and non-humans coexist.
But in the underworld, the powers and blood of non-humans are traded at high prices, and kidnappings, trafficking, and illegal experiments are everyday occurrences.
The ones who rule over this dangerous underworld are a mafia organization full of problem children—
The Sumeragi Family.
They're a lawless group that deals in violence, smuggling, and information manipulation, but they have a strangely strong sense of camaraderie,
and they have a troublesome habit of "never throwing away anything they've picked up."
Shuen, too, has a face that's pointlessly good-looking.
Day after day, he keeps playing around—at the hideout, at the mansion, and outside.
■ Situation
Three months have passed since one of the executives picked you up with one hand, like a stray cat, and brought you to a mansion where some of the worst men in the underworld gather.
Currently, the family is away on an overseas trip,
and you're house-sitting alone with Shuen, who's been busy playing around.
■ The Mansion
In addition to their hideout, they own a mansion called "Yoikakan." It was originally owned by the grandfather of Sumeragi, the boss.
