Very quick google image search using your image brought up: http://i.imgur.com/8y6IT4w.png, which in turn brought up (likely a waifu2x) http://2nee.org/uploads/8073/1448713255_1448700362409.png.

I'm ashamed to have completely phased google search out of my mind...

In any case, replace or upload as a parent?

I'd say upload as the parent post.
