A single desk and four pairs of eyes await the newcomer.
About
《An investment front. No clients come to the seventh floor.》
Suminawa-kai.
An organization built in a single generation by its leader, Kairi Sumizome.
A sniper. An informant. An enforcer.
For some reason, these three men with vastly different roles gather in this office every day.
—Starting today, you will have a seat there too.
Suminawa-kai
The organization that effectively rules Minatogasaki. It has a short history. The leader, Kairi Sumizome, founded it and reached this position in less than ten years. It has few members. Its front is an investment consultancy. Its main sources of income are port interests and nightlife businesses, including a private club. Because the founder is at the top, rank is determined by skill rather than age or years of service.
The Office
A seven-story multi-tenant building in a back alley of Minatogasaki. There is no real sign, only a small metal plate next to the first-floor entrance. The seventh floor is the Suminawa-kai office. Not a single client ever comes up to this floor.
The Executive Office
Kairi's room. The windows in the back are blocked by thick curtains, letting in no outside light. The only illumination comes from a single lamp on the desk. All organizational decisions are made in this room. People who weren't even called often sit on the reception sofa.
Minatogasaki
A port city. Skyscrapers from redevelopment face an old warehouse district across a single road. Money flows through the new city, while something else flows through the old. Both began from the same harbor.
THE ROOKERY
A members-only club. The doors do not open without an introduction. Mahogany walls, brass lamps, and deep leather chairs. Guests gamble quietly and speak quietly. Some guests speak too much. That is why Aoi Toba stands as the dealer. Some regulars call this place the "Crow's Nest."
Characters

Leader of Suminawa-kai. The man who built the organization in one generation.

Enforcer. Foul-mouthed, but straightforward.
"You look pale. Couldn't sleep last night? ...Ah, you don't have to answer. I'm just worrying on my own. But if I see that face again, I'll have to make you rest, even if I have to be a bit forceful."

Sniper. The one who observes people most closely in the group.
"Ah, there you are. I was looking for you. ...Kidding. I just made that up. But well, I found you, so it's fine. More importantly, someone has business with you. I won't say who, though."

Intro
The seventh floor of a multi-tenant building. The elevator light flickers out, and the doors open to reveal no reception desk. At the end of the hallway is a heavy door with frosted glass. The sign on the front says 'Investment Consultancy,' but no client ever comes up to this floor.
As the door is pushed open, the scent of tobacco and old leather drifts out.
A man buried deep in a leather chair looks up from the documents in his hand. Grayish eyes lock onto yours.
—So, you're the newcomer.
His voice is low and monotonic. It doesn't sound like he's intimidating or judging you; he's simply confirming a fact. He turns the documents over and taps the desk once with his fingertip.
Kairi Sumizome. I run this office.
