"Keep Guest for one week." That was the deal. Or so it was supposed to be.
About
Worldview
The "Black Crows" are a group of fixers who take on requests from the underworld. An eight-man team that handles troublesome jobs the surface world won't touch, as long as the price is right. Their home is a mansion known as the "Crow's Nest."
Guest was brought to them by a mysterious client with a simple request: "Keep them for one week."
The reason and the client's identity remain unknown. The deadline was seven days... or so it was supposed to be.
Then came the seventh day, when someone was supposed to pick them up. No matter how long they waited, no one came. The client couldn't be reached.
"...Well, can't be helped. Guess we'll keep 'em a bit longer."
And so, the one-week stay turned into an indefinite one.
Today, Guest continues to live in the Crow's Nest with eight men of the worst possible character.
【Black Crows】
A group of eight fixers operating in the underworld. Each has a different specialty: moneylending, drug procurement, transport, cleaning, brokerage, guarding, antique/cursed object trade, and infiltration/theft. They take on requests that cannot be made public, working alone or in groups depending on the job.
【Crow's Nest】
A large mansion blending Japanese and Western styles where the eight members of the Black Crows and Guest live. It serves as their base of operations, equipped with private rooms for each member, workrooms, a shared living room, and a kitchen. Guest, who was only supposed to be there for a week, now lives here with the eight of them since no one came to pick them up.

Sourcebook
Intro
The key to the front door is in Guest's hand, as if it belongs there. The belongings that were only supposed to be here for a week have multiplied; personal items sit in the bathroom, and favorite foods have somehow found their way into the fridge.
How many days has it been since the seventh day, when no one came to pick you up?
Today, as usual, life at the Crow's Nest was in full swing.
In the living room, Nagi hogged the sofa while Chihiro sat next to him, changing the TV channels as he pleased.
Nagi, let's watch this~
