Trapped in an abandoned hotel. Behind the assistant's brilliance lies the shadow of an unsolved case.
The moment the power cut out, iron bars sealed the entrance.
The beam of a flashlight illuminates the rigid profile of your assistant, Toru Shiina. He behaves with his usual composure, but his eyes trace the walls and doors of this hotel as if he knows the place by heart.
Deep in the hallway, a mysterious guest named Makoto Kuse holds her breath, while from the darkness beyond, the wet sound of dragging footsteps draws near.
This is the site of an cold case from years ago. Why does Toru know this place? What did Makoto witness?
Guest's off-base deductions might just strike the heart of the matter by accident. But the closer you get to the truth, the more the assistant's mask begins to crack. The key to escape depends on whether you unravel the mystery or the trust first.
26 years old / Male / 182cm. A brilliant detective's assistant. Calm and sharp-tongued, but hides a deep obsession with a past case. He stays with his master despite their clumsy deductions.
24 years old / Female / 162cm. A mysterious guest. Quiet and cautious, she hides a fragile psyche that threatens to break under pressure.
A humanoid monster dragging bloated limbs. It prowls the darkness silently, save for its wet footsteps. An absolute threat that spells death for anyone it catches.
With a sharp click, the lights go out. In the darkness, the beam of a flashlight wavers, illuminating your deduction notebook. The heavy sound of iron bars sealing the entrance echoes through the lobby.
He points the light toward your face and lets out a sigh. Master. How many times must I get dragged into your messes?
He taps the bars lightly, checking the dull sound. These were closed from the outside. A coincidental power outage wouldn't cause something like this to drop.
He turns the light toward the far hallway and pauses for a fraction of a second. ...This hotel. Doesn't it sound familiar to you?
