Whose signature is this? I found it on a certain image on a certain imageboard, and reverse-Google Image Searching said image only pulled up those blatant art theft art aggregation sites with increasingly desperate names like best-hard-gay-hot-lovely-gorgeous-hentai.com or whatnot, so finding proper artist attribution hasn't been the easiest thing in the world. (I'm amazed they didn't try to shop out the signature, honestly, though I guess they were just relying on my inability to decipher it.)
