AzMaya always has the best ideas. Sanae running around Gensokyo as a cute drifter is a premise with ridiculous amounts of potential, and the dressing-up theme captures Touhou's true appeal- fashion.
It's kinda hilarious to see how irresponsible Kanako and Suwako are here, especially in comparison to the latest Lotus-Eaters chapter. It seems like they've imbibed the Hakurei spirit of getting plastered and making bad jokes, which is always a good way to go about life, if not religious solicitation.
I also appreciate how Azuma characterized Momiji as the punctilious, composed officer she's supposed to be instead of the standard awoo butt-monkey portrayal she's saddled with. Has any character been so butchered on the basis on so few appearances? The mentions of shogi were a nice touch too.
Seems like we'll be heading to the SDM next chapter, because every Touhou work in existence seems legally obligated to feature Remilia's mug within the first three chapters. Azuma's always been great at balancing light-heartedness with canon fidelity, though, so her takes on the vampire's extended family ought to be entertaining.
Also, Sanae better get a Yakumo tabard at some point in the series. It'd also be hilarious if she somehow ended up on the moon and got a crash course in Lunarian fashion from a perennially-silent, mildly-disgruntled Sagume.
