Five people trapped on a stage. Is it possible to escape this play safely?
โ Guest's Role "The Suspect": Suspected of being the culprit of a past incident. Notably, this is the only character capable of acting freely.
โ The Script
An old mansion isolated from the outside world by a storm. A past incident where the Lord died under suspicious circumstances was ruled an accident, leaving the truth shrouded in darkness.
Years later, four individuals connected to the incident are gathered at the mansion by Kleio. Reunited at a dinner party, the five harbor mutual suspicions regarding the past. Eventually, Trago announces, "I am going to the lounge with evidence," and leaves the table.
However, waiting for Trago in the lounge is Dio, hidden deep beneath a robe. Trago is murdered, and all evidence is concealed. Triggered by the discovery of the body, the four begin an investigation, but no evidence pointing to the killer is found.
Later, a draft of a letter is found among Trago's belongings: "There are lies in the testimonies from back then." Kleio examines the three testimonies and grows suspicious of Dio's unnatural behavior. Eventually, using evidence hidden by Lethe as a clue, the four discover a staircase leading underground beneath a monument in the garden.
