Anyone knows the source of this? Found a doujin with this picture and I am very curious!

@Sodamachine It's the cover page for Touhou Anthology vol 2. I added the artist.

Oh thank you so much! We really dug deep but couldnt find anything, even asking the people around me that can read moon runes.
It also came with a music CD, that I have yet to listen to what it is. If I want to break the seal of it that is.
