※What is a Murder Mystery?

Each player takes on the role of a different character.

Every character has their own secrets and objectives, as well as different information about the incident.

Investigate and discuss with the other players, piece together the truth behind the incident, and make your way toward the conclusion of the story.

But be careful.

The culprit behind the incident may be one of you.
