Visual Novel
Gameplay in this choice-based visual novel involves reading through the story while making choices at certain key points. Different decisions may lead to different outcomes, story branches and endings.
The Showa era. Several years after the war, a series of gruesome murders are causing unrest among the population.
Takashiro Shugo, former member of the Metropolitan Police Department, is asked to investigate a missing persons case by his former boss, Arishima Kazuma. Written on the request is the name "Kozuki Yura," the same name as Takashiro's former lover.

Yura's father, Kozuki Keiichiro, tells Shugo:
"You see, my daughter, Yura is... already dead."
Truth and fiction interweave.
Before long, the connection between the two incidents comes to light.
With Ueno as the backdrop, the curtain rises on a tragedy...
