"It can enter your body through any aperture."
- Naked Nest's Entry
The Naked Nest (O-02-74) is an Abnormality with the appearance of a brown, spherical mound that's both attached to the floor and covered in a strange, similarly brownish substance. Hollow and acting as a nest, multiple holes of varied sizes are visible from its surface, with beaked, brown worms similar in likeness to the nest peering out during the work process with an Agent.
Ability[]
Its ability triggers upon ending a work. When finishing a work, the Containment Unit will be covered by a screen effect similar to the surface of the Abnormality for a few moments. Afterwards, the work will end normally. During that moment, the employee might get infected and present symptoms after getting out. The chance of getting infected is proportional to the employees HP along with increasing the infection chance the lower the mood is (
Normal=30%,
Bad=60%). However, this is not activated if the result of the work is
Good.
At first, the infected employee will have small brown circles present on their face, which is the first sign of the infection. After 9-14 seconds, the infected will begin to show other symptoms, namely a green cloud in its face and only 50% Movement Speed. The infection has a 30% chance to spread to employees near the infected. After presenting symptoms for 30-40 seconds, the infected will transform into a minion of The Naked Nest. This can be prevented by killing the infected or passing the day before they start to transform.
The transformed employee will have a new appearance, similar to a humanoid version of the nest. They will discard their weapons and attack employees with their bare hands, inflicting (3-5) Red Damage. Infected employees will not be targets of the transformed ones and will not attack the transformed ones, but they will attack the infected ones if they are trying to suppress them. If the attacking employee is transformed while being attacked by other transformed employees, they will continue to attack that target for some time until leaving the area.
The transformed employees are considered 'Out of Control', can still be healed by the Main Rooms and don't make any LOB Point penalty when ending the day with them alive.
Origin[]
Its origin is currently unknown.
Details[]
The Naked Nest responds to the four works in order of best to worst: Instinct;
Repression;
Attachment;
Insight.
Like all Abnormalities, its energy output is determined by the number of PE Boxes (Positive Enkephalin boxes) at the end of the interaction.
The Naked Nest's emotional state is divided into 3 sections: Bad,
Normal, and
Good. Completing 0-8 E Boxes will cause it to feel
Distressed, completing 9-14 will cause it to feel
Normal, and 15-22 will make it
Happy. Its usual cooldown timer after a task is around 10 seconds.

Story[]

The Naked Nest's encyclopedia portrait
- "※If you spot an employee whose face is turning dark green, please report it to the department’s Sephirah immediately. Be advised to verify that the cause of discoloration is not a simple stomachache. When suggested to visit the medical ward, those who have a stomachache would reluctantly agree, but an infected employee would try too hard to act as though nothing is wrong.
- In this situation, try not to alert the employee that anything is out of the ordinary. When the host becomes agitated, the infection will speed up. If the skin begins to change, that means at least 30% of the host's brain has already been consumed. Any conversation at this point is the Abnormality's attempt to mimic the host's behavior, so don't pay it any mind."
- "The Abnormality resides inside the host's brain, and the host will not be able to feel any physical sensation. You can try stabbing the employee with something sharp, feigning it as a mistake, but this is not recommended. As mentioned before, the host should already be around 30% merged with the Abnormality, so conversing will be impossible."
- "It can enter your body through any aperture."
- "This doesn't mean covering up your orifices will impede its entrance."
- "But it will help ease your mind to cover up as much as possible when you enter the Containment Unit."
- " ‘The Naked Nest's final destination is the frontal lobe."
- "You will become the serpent's nest, attacking anything in sight."
- "Please understand that we will be forced to fire on sight and burn your corpse should you become a nest."
Flavour Text[]
- "The Naked Nest appears to form a wet and sleek sphere. It is not unreasonable that it would mistake <name>’s brain as a nest."
- "If <name>’s skin becomes a hideously green shade, it is already too late for them."
Trivia[]
- Its ability works similarly to Queen Bee, with the exception that possessed employees can infect while attacking and aren't required to kill the target. Additionally, possessed employees don't count as minions, meaning they can be killed by Execution Bullets.
