Honestly, iunno; best-case, you could try image-searching the occasional stock art on yugioh.com, otherwise the Wikia could have some lying around that you could then search up and get other ones.  I tried using the image of Yuzu on the site and it found the one on her character profile on TVTokyo’s site, rendered off the background and all, so it’s worth a shot!
