If an ordinary person living in the Taisho era.
Encountered people around him disappearing for no apparent reason, and even rumors of wild beasts or monsters harming people.
Who would he most readily think to contact?
Naturally, the Far East's official organizations.
People living in big cities would go to a police station to report it.
Those living in small towns or even villages would also seek out the local neighborhood association, or ask for help at a shrine.
Especially the Tokyo Metropolitan Police Department.
It had an enormous backlog of recorded case reports and files.
No one could say how many of them actually involved demon attacks.
And...
It was not only the most recent cases that needed attention.
Those long buried in the archives could not be overlooked either.
Unlike ordinary criminal cases.
Even unsolved cases from twenty or thirty years ago could be quite useful to the Demon Slayer Corps.
Once the statute of limitations had expired on an ordinary case, or decades had passed.
It no longer held much value in the eyes of the Tokyo Metropolitan Police Department.
But the Demon Slayer Corps was different.
Because demons... had long lifespans.
Several recent cases and an old case from fifty years ago could very well.
Have been the work of the same killer.
This was actually a very important source of intelligence.
Previously, the Demon Slayer Corps could only rely on other nobles, priests, or individual "collaborators" in the Tokyo Metropolitan Police Department who had encountered demons to help look through the records.
These scattered, unsystematic methods, lacking any sensitivity to intelligence.
Made it difficult to efficiently and thoroughly uncover demon incidents that might have been reported.
How would they search?
They could only ask the staff on duty whether there had been any "strange" cases
