Agreed, but I've been trying to find a name for months. Best i could find was that she's a dungeon and fighter character/oc.
I play the game extensively but I’ve never seen her before, not even in the newer areas. Even via player character and avatar/skins there isn’t any costumes that gives ears that look like that.
Unless she’s a humanized version of the furries from Pandemonium or personification of Apostle Delezie, even if she’s from dungeon fighter and is an oc, then there is no way to give her a name except unless the artist specifically state so.
