Welcome to the board, Fire Kid Jimmy
. Please don't make "bump posts" or double post, please.
As mentioned on your first post by a member of staff, this thread will be merged with the cosplay
But to quickly answer your question, no character wears a ring like that...it kind of just looks like a ring that's designed to look like automail. So perhaps it could also go in the Merchandise thead
So I'll close this thread for the time being, and it will be merged with one of the aforementioned threads shortly.
