DFer has a recurring OC, but there's still no name to it. In his most recent dA upload of her, he calls it "my OC", and otherwise it's been titled as "Anime Fan Girl" (earliest dA appearance; post #1187538) and "Multi-cosplay girl". It's been acknowledged as a mascot of sorts for Jigoku Producciones, which I feel should be the basis of the tag, but I don't know how would be best to do so.
jigoku_*_(dfer), what I figure so far.
