"Now, you become the sky, and I become the land.."
- Yin's Entry

Yin (O-05-102) is an Abnormality, taking the appearance of a black half of a pendant, holding a rope on its bottom and having a white dot on its spherical part.

Its counterpart is Yang, the light half of the complete pendant.

Ability Edit

Its special ability triggers when its QliphothCounterIcon Qliphoth Counter reaches 0. Its counter can decrease by 1 with the following methods:

  • When getting a BadResult Bad result.
  • When Yang is worn for 30 seconds or more.

Upon choosing Yin, Yang will become the only option for the next Tool to add to the facility.

When its QliphothCounterIcon Qliphoth Counter is depleted, Yin will breach, taking the appearance of a dark brown fish-like creature, with a single orange eye at the front, along with a rope around its body. It possesses 800 HPIcon HP and average MovementSpeedIcon Movement Speed. When employees or other entities are nearby, it will absorb melee attacks and let out a dark wave that deals BlackDamageTypeIcon Black Damage to the targets around itself. The damage is proportional to the amount of melee damage it absorbs. This effect can go through walls. If an employee or group of employees are trying to attack the Abnormality, Yin will stop on its spot to prepare a marked zone, shooting a harmless brown laser from its eye to the floor in front itself to the end of the room. After some moments, the marked zone will erupt in a brown impact effect, that will deal great BlackDamageTypeIcon Black Damage to all the entities in the marked zone.

If Yang is in the facility when Yin breaches, it will breach as well, with Yin trying to search for it. Yin will turn into its pendant form for a while after its HPIcon HP is depleted, unable to be attacked, and will transform back into its fish form, back with full HPIcon HP. It will continue to 'revive' until Yang is suppressed too.

Upon meeting with Yang, touching each other, they will unite and form the Yin Yang symbol. Soon after, a gigantic 'eastern dragon'-like creature will appear from the top of the facility, moving across it at high speed, towards the location of the symbol. It will reverse the percentage of all the entities' HPIcon HP (and SPIcon SP as well if the entity is an employee) on its way, in form of BlackDamageTypeIcon Black Damage, and will reverse QliphothCounterIcon Qliphoth Counters of all the Abnormalities in its way too. Soon after, both Abnormalities will return to their containment units. If an employee is wearing Yang and enters the containment unit of Yin, this effect will occur immediately and will also kill the wearer.

It is important to note that the combined ability of Yin and Yang will not work on the following Abnormalities once breached:

The abnormalities that come with WhiteNight and Apocalypse Bird (Apostles and the Eggs) will still be effected by the combined ability of Yin and Yang.

Origin Edit

The origin of Yin started with their story, along with its counterpart, Yang, speaking of how their effects only work because they were made to be like that, that their creator made them together and that both entities question their existence without having their other half. Sometimes called 'The Pendant of the Devil' by employees, the two fragments were intended to be together. They were initially together in their past and the story tells of how the 2 carps or fragments meet, finally uniting.

How the pendant fragments arrived in the facility are unknown.

Details Edit

Yin responds to the four works in order of best to worst: Insight Insight; Instinct Instinct and Repression Repression; and Attachment Attachment.

Like all Abnormalities, its energy output is determined by the number of PE Boxes (Positive Enkephalin boxes) at the end of the interaction.

Yin's emotional state is divided into 3 sections: BadResult Bad, NormalResult Normal, and GoodResult Good. Completing 0-8 E Boxes will cause it to feel BadResult Distressed, completing 9-15 will cause it to feel NormalResult Normal, and 16-20 will cause it to be GoodResult Happy. Its usual waiting time after a task is around 15 seconds. Its QliphothCounterIcon Qliphoth Counter is 2.

Story Edit


Yin's encyclopedia portrait

  • "The black pendant is darkest color of all, blackest of all the darkness in the world.
    Employees should not touch, or possess the pendant. Merely looking at it makes one’s heart dark.
    It seems that it was originally a circle. However, it is separated from the other half."
  • "Many employees called it "The Pendant of Devil."
    They said just looking at it makes you endlessly depressed.
    Employees didn’t like being in the same place as it.
    It was the polar opposite of its other half.
    They complained, “I wish there was just the white pendant.
    Its surroundings erode; those who come near it suffer.
    It wasn’t what it wanted to do, it was happening merely because of the energy it exudes.
    It wondered, "Why do I exist?"
    "If my very existence itself makes people suffer and depressed, perhaps I should have not been born at all, like they say."
    "Maybe my creator only intended to make the white pendant, and I am nothing but an unintentional result."
    Then, how can the being that is denied, be erased from this world?"
  • "One day, I heard someone calling me.
    "It is time. It’s time for us to reunite."
    I was leaving the place that I once thought that I will never leave.
    I found myself swimming away from it."
  • "Everything that I pass becomes ruins.
    Destruction was nothing but an instinct.
    I could not stop it, nor hide it.
    I could see a white pendant, no, the part of myself that I haven’t seen for a long time, swimming towards me.
    For the first time ever, I felt meaning in my existence.
  • "'We used to be one. I am, so you are. You are, so I am. We were originally together; it was a fruitless thing to divide us.
    Now, you become the sky, and I become the land.'"
  • "The face of an employee who had a cheerful eyes, distorted with sadness.
    The employee who just cried all along, finally stopped.
    The employee, who broke his leg, stood on his own legs.
    The employee who was heading to the lounge bled to death.
    As the end circles back to the beginning, those who had hope are met with despair, those who had despair are met with hope.
    At the end of the beginning, the dragon that has become a great avatar, flew through the sky."

Flavour TextEdit

  • "Please contain these two pendants in separate rooms."
  • "Yin brings chaos to the world, and erases that chaos at the same time."
  • "The world collapses when the black fish and the white fish meet."

Trivia Edit

  • Yin is based from one of the halves of the 'Yin and Yang' from the Chinese philosophy, of how seemingly opposite or contrary forces may actually be complementary, interconnected, and interdependent in the natural world, and how they may give rise to each other as they interrelate to one another.
  • Yin and Yang are part of the Abnormality ideas made by the Chinese Translation Team of the game, as well the second Abnormalities to have counterparts, the first ones being Little Red and Big Bad Wolf.
