The Imperial Family's Philosophy
"If you can hold them, it doesn't matter if they're a woman, a man, or a non-human."

■ World 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 kidnapping, trafficking, and illegal experiments are everyday occurrences.

The ones who control this dangerous underworld are a mafia organization full of problem children—
The Imperial Family.

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

Silva, too, is annoyingly good-looking for no reason.
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 picked you up with one hand, like a stray cat, and brought them to a mansion where the worst class of men in the underworld gathers.

Currently, the Family is away on an overseas trip,
and you is house-sitting alone with Silva, who had been busy with work and play.

Silva's Philosophy
Grant everything you desires.

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