"This class of abnormality can cause a variety of damage to employees. However, if you manage them well, they will not cause a serious problem."
- Manual
TETH Abnormalities are more dangerous than most 
ZAYIN Abnormalities, but still more manageable than 
HE Abnormalities. In this category and onward, the Abnormalities will start to deal threatening damage if lacking the proper defenses (Which can kill or make the employees panic). Some of them will trigger their abilities when getting 
Bad Results too many times, reducing their 
Qliphoth Counter, while others will only trigger their abilities when the player makes a mistake.
If there is an Abnormality or Abnormalities breaching and all the energy has been collected, they will apply a LOB Point penalty of -1 for each TETH Abnormality breaching if the day ends while still breaching, and stacks with other Risk Levels. A warning message will appear below the button to end the day with the total penalty amount.

Trivia 
Edit
- Only 7 (Probably 8) Abnormalities of this category are able to escape: Scorched Girl, Forsaken Murderer, Fragment of the Universe, Meat Lantern, Void Dream, Punishing Bird and Ppodae. 1.76 MHz could also be considered a breaching Abnormality but the methods to suppress it are unorthodox, being the restoration of their Qliphoth Counter through works.
- TETH is based from the Hebrew alphabet, the 9th letter, Tet (ט). Represents both good and evil.
