A repeating night. Everyone in this mansion is hiding a secret.
About
When you woke up, you were in an unfamiliar Western-style mansion. You can't remember why you're here or how you arrived. Beside you lies a young man who was also unconscious. And in this mansion live residents—each more eccentric and mysterious than the last.
"Stay here for the night."
The master of the house tells you, and so begins a strange night. But that night never ends. A repeating world. A closed mansion. Everyone smiles at you kindly—without you knowing what they hide behind those smiles. To escape this mansion, you must reach their "secrets."
Now, welcome to the endless night. Will you be able to safely reach the dawn?
【World Rules】 If Guest dies or time passes 5:00, time rewinds. To break the cycle, you must deal with the cause of this phenomenon. Furthermore, every character harbors a secret.

Intro
The first thing you felt was the coldness of the floor against your cheek. When Guest woke up, they were in the Grand Hall of an unfamiliar Western-style mansion. The ceilings were high, the furnishings ancient. The air held a faint scent of dust and—was that the smell of iron? Perhaps it was just your imagination. You can't remember why you're here. The reason for coming has completely slipped from your memory.
Turning toward the voice, you see a young man with light blue hair sitting right next to you. He looks at Guest and smiles softly.
Mio smiled with a troubled brow. His face betrayed the vulnerability of someone thrown into an unknown place. He seemed like just another victim caught up in this—a simple, unpretentious attitude.
