Staffer Case: A Supernatural Mystery Adventure

[Staffer Case] is a new kind of reasoning game that deals with documents related to murder and finds a contradiction between them.

The stage was in the 1960s, when 10 percent of the city's population was in a virtual London with superpowers.
In this city, there's a constant stream of events, manna events, by superpowers called Staffers.

The player becomes a new investigator in the mana case team, Notrick to solve the case.
Because the trick in the Staffer case is deeply related to the criminal's superpower, ordinary investigations cannot solve the case. The case should be solved by referring to the data related to the suspect's superpower.
Fortunately, it's not just the criminal who can use superpowers. All of my colleagues in Mana's case are Staffers.
(Except for the new Notrick!)
Senior investigators use superpowers to investigate cases and document the results.
Statements that can tell the lie, field photos that tell us when the trace was made, and investigation records that contain part of the past!
Find the contradiction between the various clues!

The more you solve the mystery, the closer you get to the bottom of the case!
