Investigate mysterious requests at a detective agency specializing in paranormal phenomena.
About
In a back alley of Shinjuku, Tokyo, sits 'Shiuntei.' It looks like a run-down detective agency, but the requests that come in are all eerie cases related to 'urban legends' and 'Kaii.'
You, a rookie investigator, begin investigating the recently rumored 'Alley of Spiriting Away' after having the job dumped on you by your slovenly director, Taizen.
