So, my comment about Kyubey being in the picture got down voted. I'm not sure why, since it really is. You can see him in the background pattern on the middle left side, near where Ahri's tails diverge. You can say it's just an effect and that the author had no intention of doing it, but I think he did. The pattern there is different, and the lines for its eyes and mouth are obviously drawn with that intention.
