Example of SCP-897-KO manifestation

Item #: SCP-897-KO

Object Class: Keter

Special Containment Procedures: Foundation web analysis bot "ASMER" is to analyse Youtube's ASMR category videos and delete all videos with signs of SCP-897-KO. Then, affected individuals should be searched and amnesticised, if traceable.

Description: SCP-897-KO is a cognitohazardous video that repeatedly appears on the video-sharing website Youtube. SCP-897-KO is typically uploaded with various titles and thumbnails that are reminiscent of an ASMR1 video. The account that uploads SCP-897-KO has no other activity records and attempts to trace the account's owner have all failed.

After manifestation, the video manipulates Youtube's recommendation algorithm via unknown methods and appears as a related video in regular ASMR videos. Affected civilians have been exposed to the video mainly through this route, especially by the 'autoplay' function.

SCP-897-KO is 53 minutes and 50 seconds long. The cognitohazardous effects are shown in three stages, not induced by visual stimulation only. The video is comprised of four stages with different anomalies.

  • Stage 1: 00:00 ~ 01:23. No notable anomalies seen.
  • Stage 2: 01:23 ~ 23:45. Viewers reported that they felt mild comfort at the sound and action of teeth scaling done in the video. However, some are also reported to end up watching the video voluntarily.
  • Stage 3: 23:46 ~ 40:10. Viewers reported immense satisfaction and comfort and reported severe discomfort when the mistakes were made in the video. Notably, people with psychological trauma related to dentistry reported similar discomfort. At this stage, viewers feel very tired and fall asleep. Viewers who were already asleep at this stage experience sleep paralysis.
  • Stage 4: 40:11 ~ 53:50. Viewers feel extreme discomfort and pain as teeth extraction starts and attempt to stop or actively avoid watching the video. However, such activities are impossible for those undergoing sleep paralysis. If one watches the video to the end, they fall victim to the palatohazardous anomaly of SCP-897-KO.

The palatohazardous anomaly worsens over time and can be classified into early, middle, and terminal stages. The development of the anomaly differs from subject to subject but shows a correlation to past dental history and psychodental resistance.

  • Early Stage: Subjects feel a taste from their teeth. This taste differs on the individual but is commonly described as intense. This sensation is strengthened as time passes, and most subjects try to feel this taste by licking their teeth. The more they show these actions, the faster the development of symptoms.
  • Middle Stage: Subjects are addicted to their teeth. To better feel the taste, subjects try to destroy some of their teeth, sometimes filing their teeth with a hard object or grinding their teeth together. Such actions usually cause serious harm to the subject's dental health.
  • Terminal Stage: Subjects extract their teeth and ingest them. This process continues until all teeth are ingested. However, as the last remaining teeth cannot sufficiently crack the extracted ones, the subject's oral health is severely compromised by such behaviour.

Addendum: SCP-897-KO Video Log

SCP-879-KO Video Log

[00:00] Start of video. A man is sitting behind a desk, showing his bust and jaw. In front of the man is an object similar to a complete denture with blackish plaque sticking to its teeth. The man never shows his face except for his jaw throughout the entire video.

[00:01] ~ [01:23] The man holds the object and brings it near the camera. He then slowly rotates the object and moves its mandibles, giving its structure a better view.

[01:23] ~ [23:45] The man brings multiple dental tools from outside the frame. He then removes plaque from the object and stores it outside the frame. The removal process is notably clumsy, leaving many scratches all over the object. On point [20:11] especially, some of the molar teeth are seen damaged and falling off. This part of the video is very loud, but the man's breathing cannot be heard.

[23:46] ~ [24:58] When the removal is complete, the man holds the object and brings it near the camera again, rotating the object and moving its mandibles, giving a better view of its structure. The object appears to be considerably damaged, with some of the plaque not completely removed.

[24:58] ~ [40:10] The man puts the object off the frame and moves the camera to show his mouth better. He proceeds to open his mouth, exposing teeth with a similar plaque attached. He brings various dental tools from outside the frame again and removes the plaque from his teeth. This process is clumsier than the object's plaque removal, resulting in oral and dental damage and haemorrhage.

[40:11] ~ [42:30] After the removal, the camera is moved to give a detailed view inside the man's mouth. His oral cavity is severely damaged, with continued gingival haemorrhage. The camera focuses on each tooth. The teeth are damaged and, in worse cases, cracked.

[43:31] ~ [48:30] The man puts the camera down and starts to speak in Korean. While doing so, the man brings a pair of pliers from outside the frame. The man proceeds to use the pliers to pull his teeth off, starting from the right incisor, proceeding from right to left, front to pack. The man does not stop talking in the process, showing signs of pain.

[48:41] ~ [53:50] After complete removal, the man picks up the teeth one at a time and shows it to the camera. After showing all of the 34 teeth he removed, he picks it up, puts it in his mouth and chews it. Severe oral haemorrhage is observed blood splatting as the man speaks. Sounds of teeth being crushed can be heard, although the man is unable to chew because of his lack of teeth. On [52:40], he is observed to swallow the teeth. Then, the man smiles, exposing his severely deformed oral cavity with blood spilling out of his mouth.

Monologue Transcription: Contents of what the man said in [43:31] ~ [53:50].

The first dentures were made with other people's teeth. Teeth are comprised of mostly calcium carbonates, recording seven on the Mohs hardness scale, making it useful for eating rocks. But beware, as ingestion of calcium carbonates may cause cavities, so maintain good oral hygiene by regularly flossing and brushing your teeth. Dental agriculture is a historical activity that started in ancient times. Notably, in Silla, they regarded people with more teeth as wiser.

(The man brings in a pair of plyers and puts them in his mouth.) A tooth is known to have (The top right incisor is extracted. The man moans in pain for seven seconds and trembles for 15 seconds.) 1200 calories. Reptiles can extraordinarily digest calcium carbonate, so they are known to eat bird teeth often.

(The left top incisor is extracted.) The health benefits of eating teeth are written in many medical books. Do you know that ingesting chitin can be good for your body? Many religions regard teeth as stars (The bottom right incisor is extracted.) and sanctify them. In Christianity, most notably, the teeth of saints are considered the holiest relic. This is also true for Buddhism, where teeth are regarded as Saris. (The bottom left incisor is extracted.)

Historically, teeth are considered a valuable resource. Ivory was a precious good for a long time. (Three teeth are extracted starting from the top canine to the right. The man opens his mouth and spits blood on the floor.) Human teeth were also utilised as jewellery and also used as the (The man briefly stops, moaning in pain.) first form of currency.

(Five top teeth are extracted. The man is barely comprehensible.) As such, life ends, and at the end of life, there is blood. Look out the window. See the crimson moon. Spew out all the hatred as shards of the broken moon are spilt, and the only thing remaining will be your white, glistening fangs. Use them. Rip into flesh. Drink blood. Gnaw on bones, just like what the molars did to us.

(The bottom left molar is extracted.) Extract the roots. The roots. Chew on that tree's roots. Let's use our molars. Molars are most useful for chewing food. It is mainly used to chew other teeth. That's why teeth exist. (Three bottom teeth are extracted.)

Why? (All remaining 11 bottom teeth are extracted. The man spits blood two times. The man attempts to speak multiple times in the process but quits.)

Four pairs of teeth. Cement. (The man extracts all remaining top teeth.)

It's not so bad. (The man smiles. Blood spills out from his mouth.)
