Project Moon Syndrome

A condition in which a person experiences difficulty with determining the gender of a Project Moon character.

This occurs most often in new fans to the series, as a result of the androgynous design of many characters- notable ones being Argalia (Library of Ruina), Netzach (Library of Ruina), and Hong Lu (Limbus Company).

“I can’t tell if Netzach is a boy or a girl.”
“Sounds like you have Project Moon syndrome.”
