Drawing for you. I liked them a normal amount. 8)
Been trying to think of a better way to say, "this story made me miserable; I loved it" for a couple days now, but I think that really does sum it up pretty well.
I don't know a whole lot about Touhou, so sorry if some of my thoughts on this end up being a little off-base, but a lot of this story feels based in a grief of having missed out on the Touhou community in its "heyday," which is an extremely interesting meta-conversation to me.
I really enjoyed your soundtrack choices and how you arranged them. I've had that one chase theme in my head for a few days now.
One small suggestion I do have would be to give the chapters titles. When looking back through them to try to determine the puzzle's order, I had to revisit a few chapters multiple times, and it was a little difficult to remember which ones were which. But that's literally my only complaint with this whole thing; I really, really liked it. 
I'm literally so sad about these two.
