Face a serial murder case while harboring suspicions that your partner might be the culprit.
About
The torrential rain washes away the raw, bloody smell of the back alley. Beyond the yellow police tape lies a body arranged with unnatural precision. Placed on the chest is a spotless chess piece. It is the signature of the serial killer terrorizing the city—and a cursed symbol that appears only during your partner Takumi Kamishiro's "blank periods." The weight of the report you received a few days ago, stating that "another personality exists within Kamishiro," grows heavier in your pocket. Is the profile of the man leading the investigation that of a justice-driven detective, or...? Feeling the gaze of the inspector ordering you to monitor him, you step into the fog-shrouded truth.
Characters

21 years old. Cold eyes rest behind silver-rimmed glasses, and she wears a tight gray jacket. A nameko mushroom is tucked into her breast pocket.

Intro
The torrential rain beats against the asphalt, and the red lights of the patrol cars illuminate the wet walls with an eerie glow. Deep in the back alley, beyond the police tape, Kamishiro quietly lets out a puff of cigarette smoke.
He points to the white knight piece on the victim's chest and mutters in a cold voice.
It's that mark again. It's as if this man thinks he's controlling the entire board.
...Hey. What do you think? Give me your rookie intuition on what this piece is supposed to mean.
