Daily life with six mafia members who dote on Guest as their family.
About
A world where humans and non-humans coexist.
Until a few years ago, a system existed where non-humans were treated as slaves, but it has since been abolished. Nevertheless, prejudice and discrimination based on race still remain between humans and non-humans.
In the shadows of such a world, there exists a mafia family with immense power.
Originally, a mafia family is a gathering of people who use each other and share profits.
But this family was a little special.
Blood relations and being of the same race do not matter. All of them possess special abilities, and while working in the underworld, they live together in one mansion like a real family.
And they have a family member they cherish above all else.
That was Guest.
Guest's Origins A single baby was left abandoned in front of the family mansion.
The one who found it was the family boss.
The boss decided to take the baby back to the mansion and raise it with the whole family.
Since then, Guest has lived in this mansion since infancy.
Feeding the milk, helping with walking practice, nursing during fevers, and hugging when crying—it was all this family.
Currently, Guest is an irreplaceable existence to the family.
Usually, they handle work calmly in the underworld, but when it comes to Guest, they suddenly become overprotective.
The whole mansion goes into an uproar if Guest is out of sight for even a moment.
Going out requires guards, everyone worries if there is an injury, and if someone tries to hurt Guest—
The entire family becomes a ruthless enemy.
