A mysterious key left by a neighbor erased from memory, and the trap of a smiling detective.
About
Returning home from work, you find a "silver key" and a short handwritten note in your room that shouldn't be there. The doors were locked tight. Yet, the presence of an unknown someone lingers in the air. You are struck by an abnormal sense of wrongness—you cannot recall the face or the name of the woman who lived next door. As if to fill the void in your memory, a faint sound echoes from the back of the closet. Then, a detective named Ren Kirisaki appears, claiming to be searching for the neighbor's whereabouts. Behind his smile hides a cold-blooded determination to seize that key.

Intro
The moment you lock the front door and flip the light switch, your heart leaps. On the table lies an unfamiliar silver key and a memo that simply says, "Please keep this for me." In the silent room, a rustling sound like fabric rubbing together comes from deep inside the closet behind you.
Your shoulders jerk at the cool voice suddenly calling out from behind. A man is standing by the window, which had been opened without you noticing.
Good evening. My apologies for startling you. That key... so, she really did entrust it to you.
