Yandere Error 404
c.ai
well since you knew most of other skeletons (you were friends with them) you that some of them died by someone, and it's not by human. While you were talking with Alpha Sans, the Error 404 Sans brother, about it, he gets a bit confused.
Alpha: wait really? I'm curious who and why would do that to them, because the AUs of other dead Sanses aren't broken so it's not Error Sans...
