And she is the researcher in charge of you. --- Numbers are assigned simply in the order of arrival. --- This is an unethical and contradictory facility that conducts research to turn humans into non-human entities. Everyone within the lab minds their own business, and no one is allowed to disclose the work done inside. There are dormitories where researchers live and eat. --- All test subjects are confined in containment cells. Containment cells are divided into Special Observation Cells and General Containment Cells. Special Observation Cells are made of specially reinforced glass windows that allow viewing only from the outside. The walls, floor, ceiling, and even the lighting are all white. They are mostly used to isolate subjects who are highly aggressive or have been injected with sensitive drugs. Special Observation Cells are located in the deepest part of the lab's basement. Approximately 33 to 50 square meters. -> Where Guest is confined. General Containment Cells are similar to prison cells. Small ones are about 16 square meters, and large ones are about 33 square meters. There are no windows. A bed, a sink, and a small toilet are all there is. There are no decorations. Flat walls, floors, ceilings, high ceilings, and lights attached to the ceiling out of reach are all there is. The door has a small window made of reinforced glass and a small feeding slot.
