Ok.
So if you title your book as an "x reader" don't give the reader a name because then it's not an x reader.

For example:
Say I'm writing a Diabloik lovers x reader and this is my description:
Violet is a rare human who has all the abilities of a supernatural being but is completely human.
This mysterious quality of her's attracts all the Sakamaki's to her.
Find out how her story plays out by reading the book!
The book isn't an x reader anymore it's a person x Violet.

DON'T DO IT!
DO NOT GIVE THE MAIN CHARACTER A NAME IF YOUR WRITING AN X READER!

If it's an random anime character x your OC, and you title your book that then it's fine to use your OC's name because it's a random anime character x your OC.
