Error Supremacy

The only true and right belief. So much better than Kyotem, for Error is the best.
(Error if you're reading this, me, Kyotem thinks you're amazing.)

Look, we need some Error appreciation in here. Why not just believe in Error Supremacy altogether?

Errormare

A ship between Error sans and Nightmare (he isn’t really a sans). Often confused with Killermare, but is way better because Killermare makes no sense. Don’t even get me started on Errorink. (I had to reupload this sorry lol)

Errormare fan: “My favorite Errormare fanfic was updated today!”

Your client has issued a malformed or illegal request.
