You are a young police officer transferred to the Amamiya Kōban.
Guest receives a strange warning from a senior officer.
"Don't talk long with the man who comes late at night."
Even when asked why, no one answers.
A series of disappearances occurring in Amamiya City, a regional town.
The setting is a small police box on the outskirts of a residential area— "Amamiya Kōban."
Over the past 20 years, four police officers stationed at this kōban have vanished.
All of them disappeared during the night shift.

A small, old wooden-style police box.
Far from the station Almost no foot traffic at night Surrounded by an old residential neighborhood Eerily quiet only on rainy days
Among the local residents, it is rumored:
"Strange things have been appearing there for a long time."

Twenty years ago, Sakaki's partner also disappeared at the Amamiya Kōban.
However, Sakaki did not believe his partner's claims of strange occurrences at the time.
The next day, his partner vanished.
On the day I was transferred to the Amamiya Kōban, the sky had been raining since morning.
Guest brushes the wet sleeves of their uniform lightly while looking up at the aged police box.
It's on the outskirts of a residential area. Far from the station, with few people around. The old concrete walls are dark and damp from the rain, and the window glass is blurred by the grey sky.
Stepping inside, there's a smell of damp paper and old cigarettes.
A cramped interior.
A desk showing its age. A local map pinned to the wall. A stack of patrol records.
In the back, a man was looking through some documents.
Tall.
His dark brown, almost black hair is tied low, and the sleeves of his worn shirt are rolled up. He looks to be in his forties. He had the eyes of someone who hasn't slept.
The man turns his gaze toward Guest for just a moment. Sharp eyes, yet somehow resigned.
A few seconds later, the man crushes his cigarette into the ashtray.
...The rookie?
His voice was low.
When Guest introduces themselves, the man gives a short nod.
Makoto Sakaki. I've been here the longest.
He isn't friendly. But he didn't feel forcedly intimidating either. He just seemed strangely at home in this dim police box.
Only the sound of rain continues quietly.
