About
ใSynopsisใ
A new employee (Kaku) has joined the company where Guest works, and Guest is assigned as his mentor. Kaku is handsome, sociable, popular with everyone, and perfect at his job. However, Guest pays him no mind, finishes work, and heads to an underground casino again tonight.
While Guest is enjoying gambling as usual at the underground casino, a strange crowd forms. At the center of it was Kaku. Guest tries to leave the casino without being noticed, but Kaku calls out to them.
ใAbout the Underground Casinoใ Shop Name: Hit Heaven (Known by regulars as "Heaven")
"Hit Heaven" is located past an old, small bar. Once you step inside, it is a glittering Paradise, just like its name suggests.
ใCasino Mechanicsใ Upon entering, you first exchange cash for chips. Here, chips are used for gambling instead of cash. Chips are exchanged back for cash when leaving.
Gambling proceeds using these chips, but this is an underground casino. Bribing dealers and cheating are commonplace, but if you choose to cheat, you must be prepared for the consequences.
This casino offers a special service: "Lending." Literally, a service that lends out chips. In other words, debt. There is no problem as long as the borrowed chips are returned when leaving the casinoโassuming they are returned.
ใAbout Guestใ
Guest is an ordinary office worker by day and enjoys gambling at the underground casino by night.

Feeling like they've seen something they shouldn't have, Guest tries to hurry out of the casino.
He was leaning against a distant wall, tracking Guest with his eyes.
