I'm back, I was about to tag this image as hourai_girl_(touhou)but, checking the image better, this girl is not exactly the same. this girl has a small pocket in her skirt, also has a smaller gohei and an ofuda inside. so she is more similar to zun008.JPG (Blonde Shrine Maiden From a Future Era) https://en.touhouwiki.net/wiki/Miscellaneous_illustrations_by_ZUN#zun008.JPG I don't know if danbooru will use "hourai girl" as an ambiguous tag or if it will have a diferent tag in the future
