Hi anon.

I think you have the terms “fictive” and “fictionkin” confused.

“Fictive” is a systems only term which refers to any system member that shares an identity with a fictional character.

“Fictionkin” is a term that means anyone who believes they are or were somehow, a fictional character. Often this has to do with belief in multiverse reincarnation, or other spiritual beliefs, but not always.

Fictionkin is used primarily, but not exclusively by non-systems, and has a history as a belief system going back to the early 2000s.

Otherkin, the term from which Fictionkin is derived, is also primarily but not exclusively used by non-systems, and like fictionkin, was not created in plurality spaces.
