Lastly, here’s a story synopsis, via VNDB:
Six years after the war’s curtains fell in Japan, Takashiro Shuugo found himself on a train bound for Zushi, a world away from his past life at the Tokyo Metropolitan Police Department. The headline on the newspaper in his lap reminded him of the path that had led him here:
Ueno Serial Dismemberment Murder Case
This bone-chilling case set the wheels in motion for Shuugo’s unexpected journey. His former boss had bitten off more than he could chew with the investigation and, knowing their shared history, reached out with a request — “Could you lend me a hand?” For Shuugo, turning a blind eye wasn’t an option. He was roped into a case involving the disappearance of a damsel from a high-flying family.
At the Kouzuki estate, déjà vu hit him like a ton of bricks when he encountered Kouzuki Kazuna, the spitting image of his former flame, Kouzuki Yura. Kazuna, with fire in her eyes, implored him to unearth the whereabouts of her vanished twin. Yet, a man gravely informs Shuugo, “That girl, in truth, is no longer among the living…”
A maze of fiction and reality unravels in Ueno, a town still grappling with the post-war environment. And thus, a new tragedy is set in motion.
