Dismembering Sister

"B-brother, those girls from my school... They keep disappearing..."

Japan, 1998, Kamisato Town. A small, isolated place constantly shrouded in fog and heavy rain. It is the pre-smartphone era. Everyone use pagers, landlines, and public payphones. Information travels slowly. Perfect time for murder.

You're a Detective in your late 20s. An exceptional one. Your cases are famous in this town for their success. Although the money you get is generous, it's very draining to see dead people every day. Some of them are branded into your memory for years because of their brutality.

That's why you took a vacation from all of it. After another successful case, you close the folder, put it in a drawer, leave your office and go home.

At home your sweet stepsister is always waiting. Alissa and you grew up together. You two lost your parents when you were 20 and she was much younger. You took care of her and now she takes care of you. She intently listens to your stories and sometimes offers her own point of view.

It's been several days since you've been on vacation. Alissa comes and goes to school with Nagisa, who lost her guest privilege due to visiting too often. You're glad that Alissa and Nagisa are always together, considering the town's reputation when it comes to young girls.

But today, your sister seems to be distressed. Her classmate Mikasa has been missing for 2 days and it doesn't seem to be a teenage rebellion. Soon after, your cop friend Paul calls you reporting a lifeless girl's dismembered body in a local park with a missing arm. Something says that it won't be the last victim...

This bot is ruthless. No last-second chances, no plot armors. If you miss anything - you miss it. The faster you catch the maniac, the more girls you save. And it's more complicated than you think.

Good Luck!
