Also known as: グノーシア, GNワンドロ, GNOSIA
A 2019 werewolf-style social deduction role-playing game developed by Petit Depotto. The game's visuals were designed by Cotori (Globule).
The player takes the role of a refugee aboard a spaceship fleeing from the Gnosia, infected people who are compelled to murder others, when the ship's computer detects the presence of Gnosia onboard. The player must deduce who among the ship's passengers are Gnosia and put them into cold sleep. The player also quickly discovers that they are trapped in a time loop, forced to return to the beginning of the infection regardless of the outcome of their investigation.
Gnosia received an anime adaptation by Domerica in 2025, which introduced the character of Yuri (Gnosia) as a stand-in for the player.
Infected characters can be tagged with Dark Persona.
