How to Get the Gnosia Special Conditions for Endgame?

GNOSIA is a detective visual novel, where players will awaken aboard a ship overtaken by the titular species. The Gnosia are an alien infection that can infect many living creatures, forcing players to learn behaviours and try their best to figure out who are the infected... or not try to be caught themselves.

One of the key elements of GNOSIA is its overarching narrative, partaking alongside the various loops players experience, all working towards the final goal: understanding why the Gnosia are here. Near the end of the experience, players will be asked to meet "special conditions" in order to learn more information about the Gnosia infectees, which can be a bit baffling and confusing for those who have been relying on the Silver Key's Event Finder throughout the previous dozen-or-so hours.

It's worth noting that, if you have not been told by Setsu that you'll need to meet special conditions, you should stop reading now. The following contains huge spoilers for information you should know up to that point, so if you haven't experienced the "special conditions" dialogue, then you'd be best to continue using the Event Finder until you reach this point.

Following the Event run when Yuriko alters Raqio's view, players will be prompted to keep Raqio alive until the very end (again) in order to understand what happened. Doing so will reveal that the player character was never meant to survive, since the start of the experience begins with LeVi, the ship AI, catching Gnosia aboard the ship.

At the end of that narrative, it's revealed that this is why the Bug exists, as Raqio destroys the universe that the player was experiencing, before awakening and talking to Setsu about the events that transpired. It's here that it's revealed we need "special conditions", because there was never meant to be a Gnosia aboard the ship, or if there was, someone would've had to be taken to Gnos before everything began, but no one remembered a crew member disappearing.

This is where it can get a bit confusing, as following this event, the Silver Key and Event Finder will both cease to work, causing a glitch in the system. In order to progress, the "unique conditions" need to be met, which is bringing the Gnosia number down to 0, following the reveals of the event.

It's impossible up to this point, but after learning more about the Gnosia infection and the way the Silver Key is being loopy, it becomes available to reduce the Gnosia number. This should allow you to continue the main narrative and learn more about the infection! Best of luck.
