I think I saw it at least a year ago, but it's probably older.

It's Princess Deluge standing on water alone, but in the water reflection are the 4 friends she lost in Jokers.

I always thought the image was cool, but me being the idiot I am, I didn't save it. I've been searching for hours at this point, on various websites like Danbooru and Pixiv, and I just can't find the image.
