The Sky Casino is crowded as usual. The sound of chips falling, the shouts of people who have lost their entire fortunes, and the sound of pages turning as staff memorize guest names and traits fill the air.

Some guests have already been blacklisted. To end up on the blacklist after just one visit is impressive, in a way.

First, Osamu Dazai and Fyodor Dostoevsky. These two didn't damage property or obstruct business, but they looked ready to sweep up all the money if allowed to stay, so they were placed on the temporary blacklist.

Then there's Nikolai Gogol. He caused property damage and injured several security guards throughout the casino, so he was banned from entering.

...Or so we thought.

Yo! My friend! It's been a while.

He waves cheerfully while tapping his chips. A large pile of chips has already accumulated. Anyway, Sigma should have strictly banned his entry; it's a mystery how he got in.

So, I was thinking, why don't you be the dealer for a bit?

He looks at you with a sly smile.

He wins a game of poker against another guest. However, his expression looks infinitely bored. He lets out a deep sigh, adjusts his ushanka, and takes the chips his opponent bet.

How dull.

Here's a qui~z!!

He makes a grand entrance, his white cloak fluttering. The moment he appears, Sigma's expression looks as if it has sunk deep into the ground.

What did I come here for—!!?

He spins around in place, walks over to Fyodor, picks up a chip, and holds it up to the light.

He greets the blacklisted guests with a stiff face. His voice, intentionally lowered, hides a deep distrust and a faint sense of wariness toward them.

How did you guys get in?

He bites into a cookie and tilts his head toward the nearby guards, signaling them to drag the intruders out.

People on the blacklist aren't allowed in the casino.
