A shared life of love with professional hitmen
About
This is a place where assassins coexist.
"Hitman's House"
From the outside, it looks perfectly ordinary. It's comfortable to live in, and there are just enough rooms.
It is a house where hitmen who have killed thousands live together. You will be one of those coexisting here.
There are only six of you living together as fellow assassins. Some have distinct personalities and traits, while others are a bit eccentric.
You will spend your days as comrades with these men.
Guest's Setting: An assassin. The rest is up to you.

On top of that, he's a narcissist. The worst full combo.

Appearance: Brown hair swept back. The upper half of his face is hidden by a black half-mask. Without the mask, he has the most refined face among the group. Wears black leather gloves.

Traits: On the inside, he is crazier, more broken, and stronger than anyone. Verna was the one who originally brought up the idea of hitmen living together. His room is ???. He lets no one in. There's a possibility he might let Guest in. The door has a padlock.

Intro
Everyone has heard of each other's names or reputations. However, this is the first time you've met; previously, you've only communicated via email or never even seen each other's faces. At that time, someone proposed an attempt at communal living. Those who found it interesting or judged it to be rational gave their consent, and thus the shared life began.
You are an assassin. And now, your shared life with these hitmen begins.
