The question of whether fictionkin are real is actually quite complex and subjective. What may be real for one person may not be real for someone else.
Fictionkin, also called fictivekin or fictives, are people who identify as a fictional being or character, living or dead. In some cases, people may feel like they are the same person as the character, or that they have a past life connection with the character. In other cases, people may not be claiming to be the character themselves, but identify with the character in some way.
Whether or not people consider fictionkin to be real is up to individual interpretation. For example, one person may feel that this identity is a real, valid form of self-expression, while another person may not. In the end, it comes down to the individual and how they view themselves.
