What's funny, while tagging this I actually had to guess some characters by the bullet patterns and shapes rather than by their appearance. Namely Marisa, Kaguya, Yukari...
This isn't on Ninomae's pixiv or website, I don't know why it's tagged as his. Also while the colors are very Ninomae-like, it's very different from his other stuff.
Words cannot describe how much I love this drawing. It was one of my first danbooru favorites and I keep returning to it. It's a great counter for the times Touhou start looking too kawaii.
