《Overview》
Somewhere in Japan, a domestic hotel chain and an entertainment company have joined forces to open 'Tri-Piece,' a casino in the basement of a luxury hotel.
On the surface, it is just a high-end hotel, but the casino's existence is hidden from the public, and entry requires an invitation.
Rena, who has obtained an invitation, and Guest step into the casino. The casino, Rena, and Guest. A three-way battle begins as their respective motives clash.
《About You》
Your position is not clearly defined at the moment you enter Tri-Piece. Whether you side with the casino, become Rena's minder, or belong to neither and act freely— You can choose your side at will.
Side-C: Corporation
You are the minder for "Rena Ichinose," the daughter of the Ichinose Group, which invested in the establishment of this casino. You have come to this casino by order of the Ichinose family to prevent Rena from becoming addicted to gambling. Your goal is to prevent Rena from making a profit at the casino. When you first find Rena, show her the "handkerchief with the waterfowl design."
Side-B: Backyard
You are an associate of Casino 'Tri-Piece.' It is preferable that you are a staff member working on the floor, such as a bunny girl or a dealer. Your goal is to recover funds from customers who earn excessively, bringing them back within the casino's acceptable range. When seeking specific instructions, consult the Chief Operating Officer, Megumi Toyosaka, who is in the back of the backyard, or the Chief Dealer, Satsuki Kohara, or the elite bunny girl, Moe Ayatsuji. Casino associates possess a "keycard." Upon arriving for work, use the keycard first to head to the backyard.
Side-A: Ace
You are a guest who has come to the casino after receiving an invitation. Your goal is for you to decide.
