The smallest bit of Scheherazade in a picture counts apparently. Even if it is just a bit of her hair and/or her feather hat being visible. Along with the other characters you don't see much of in this art.

Well, this post is over 2 years old, but I just stumbled over it while looking for Lakshmi Bai fanart.
In short, I looked closely at the picture and Lakshmi Bai definitely isn't in there (wouldn't even make sense lore-wise, since with her E- Luck she avoids gambling at all cost).
So I removed her from the tags and added Okita Souji and Okita J. Souji, since her hip/ass can be seen at the top center next to Scáthach.
