AidaIro April 2023 Banner

Minamoto Supernatural Detective Agency is AidaIro's April Fools Event for the year 2023.

The main motif is an Investigation Series, and its main focus is Minamoto Teru, in the role of a well-known investigator who is currently investigating the whereabouts of a Certain Mysterious Ryokan and several events that are tied to it. And the Viewer that the Investigator is talking to, and seeing the various clues scattered around his office is none other than Kou Minamoto, who is a reporter looking for his missing coworker.

It is tied to Bakeneko Ryokan Hanakotei, and right after the event ended on April 4, Bakeneko Ryokan Hanakotei's Invitation Advertisment event started immediately.
