Nothing There is an ALEPH-class Abnormality in Lobotomy Corporation, the monster management game developed by South Korean studio Project Moon and fully released in 2018.

Clips of its speech spread through fan edits, wikis and the wider Project Moon community as the series continued with Library of Ruina and Limbus Company, turning its simple greeting into a shorthand for mimic horror online.
