If a fire breaks out, you must flee.

Exploration Stage: Octopus Citadel
From: Alicia
Description: So far, I had thought that it might be just a coincidence, but I still think that the fire was deliberately started by the designer himself. Let's look for the fire extinguishing flask that was provided to put out the fire. If it is found, it will be conclusive evidence.
Completed: I don't see any water in this extinguishing flask at all. And there are no traces of sediment, which is always found in fire extinguishers. This flask probably contained nothing from the beginning. The designer started the fire. And they did not intend to extinguish it from the beginning.
