Staffer Case is a new sort of mystery game, asking players to find clues, arrange them into documents, and point out the contradictions between them to solve a series of murders.
The game is set in a fictional version of London in the 1960s where 10% of all residents have some sort of supernatural ability. In this city, incidents involving staffers, the people who have these abilities, are constantly occurring.
Players take the role of the Mana Affairs Division's newest detective, Notrick, in order to make sense of these incidents. Since the tricks buried within these staffer cases, at their core, revolve around the supernatural abilities of these criminals, conventional investigative methods won't be enough to solve them. Instead, players will have to rely on the documents that explain what their suspects' abilities entail in order to make sense of everything.

Fortunately, it's not only the criminals who have these supernatural abilities.
All of Notrick's fellow detectives at the Mana Affairs Division are also staffers (Excepting gumshoe Notrick himself, of course!). The senior detectives use their supernatural abilities to investigate the crime scenes and organize their findings into documents.
Testimonies that account for emotional distress, invisible trace that tells when evidence was left, even memories that remain in objects—find contradictions using the various clues at your disposal!
Each mystery unraveled leads you closer to the truth lying at the heart of each case!

Solve five cases involving supernatural powers!
Play through two substories that delve into the characters' backstories and personalities!

[Case 1 : Backstage]
Notrick, an assistant from a small town detective agency, receives a letter from the Pheno-mana Bureau and heads off to London.

[Case 2 : Pet Shop]
Creechers: the mutated results of Pheno-mana.
An incident occurs at a creecher breeding facility.

[Case 3 : The Wizard's Room]
Staff: tools that exist with mysterious powers.
The body of a famous staff collector was found sliced in half, vertically.

[Case 4 : Mistletoe]
Oppenheimer: the threat level applied to Pheno-mana as dangerous as atomic bombs.
In the basement of the Bureau lies a facility that houses these Oppenheimers.
[Case 5 : ???]
Present events, past events, and the truth that lies beyond...
