I swear that the thing she's holding in the screenshot is a sword. Considering that the story of the game apparently involves the PC's weapons suddenly coming to life, it would make sense that the character they are facing is some sort of sword youkai. We are still talking about Stage 1 though, so she's probably a semi-related random.

That was my very first thought when I saw the new boss. (Also the tail seems to be one of Sakuya's knives) Only 15 days, guys and gals! Then we know the truth!
As someone who got into Touhou shortly after DDC was released, it is super weird to see people speculating about the thing that she's holding, with absolutely nobody suggesting the possibility that she isn't holding anything at all...
