Have a question figured the FT community would at least give some clue

Doubt most of you even remember me which is probably for the best, so I won't bring up the past. The question I have, I figured that the community or whoever sees this could help, being bigger FT fan's then me by a wide margin. So this Picture I found of Cana from a cover page or some kind of Illustration Mashima did, I have no clue where it's from I reversed Image searched it and nothing popped up, any clue where it's from
