I still need to get in the habit of mentioning people prior to finishing my post. I know mentions don't actually work right if you edit them in after the post is up, so I just wanted to boop you this way to let you know that it did at least cross my mind right as I hit "post". :(
No, I've never seen that anime myself. Gorou's face-claim is just fan art of some guy from RWBY (which I've also never watched). Do you mean the character himself is familiar, though, with the reasons for wearing a mask or something?
