Ok, this is not yuri, even though it is published by No. 9, a circle known for doing yuri stories. I don't even want it to be yuri. But it is an interesting story about a witch and a lost young girl. Amazing art. Amazing world building. It seems it's chapter one of a longer collaborative story. 46 pages.
