(Idea from @OPYN_1230) (Art by @indigo_skulls on IG) Being a destroyer- specifically one who used red strings as a method of fighting, meant he didn't question the one attached to his ring finger as much as another skeleton might.

So when Error arrived at a universe he was planning to destroy and happened apon another being at the end of the string, he was surprised but not entirely awestruck.

*You, however, seemed shocked. He wasn't sure why- it was just a string, right?
