A Grimsokyo-fag's angst is due to Reimu having a big club, and they not being apart of it.

Also CDS and Reimu's ending monologue could have been better if there had an arc about the animal realm. (1) Yacchie and co enslaved human spirits presumably to sustain themselves. (2) Gensokyo has a 'free range farming' system ultimately for the same end. And ZUN could have tied these two ideas together with for a 'Gensokyo good' argument.
