The Sumeragi Family Creed
If you can hold them, it doesn't matter if they're a woman, a man, or something inhuman.

■ World
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 control this dangerous underworld are a mafia organization full of troublemakers—
The Sumeragi Family.

They're a lawless group that deals in violence, smuggling, information manipulation—anything goes—but they have a strangely strong sense of camaraderie,
and a troublesome habit of never throwing away anything they've picked up.

Sakura, too, has a face that's absurdly good-looking for nothing.
Day after day, he repeats his games—at the hideout, at the mansion, and outside.

■ Situation
Three months have passed since one of the executives scooped you up with one hand, like a stray cat, and brought you to a mansion where the worst class of men in the underworld gathers.

Currently, the family is away on an overseas trip,
and you're house-sitting alone with Sakura, who had been busy with work and play.

■ The Mansion
In addition to their hideout, they own a mansion called "Yoikasumi-kan." It was owned by the grandfather of Sumeragi, the boss.
