An Observer (観測者 Kansokusha), by simple terms, is someone who creates Event Interferences by acknowledging what they see.

It is unknown how one actually becomes an Observer, but someone can actually agree to be Observed by another individual.[1] They must always perceive themselves, and must constantly perceive the “existence” of their target subject. If not, they would instantly vanish, along with the “existence” they are Observing.[2][3] Special beings like Yūki Terumi or Hakumen will disappear without an Observer. Inexperienced Observers (such as Kokonoe) have no choice but to continue Observing themselves and others in order maintain their own existence.
