Touhou Sorting Results/Spaztique's Perfect Waifu?

Turns out the best chose for me hasn't even been brought up yet. Now, I don't believe in "having a waifu," but it seems Kasen is probably one of the most practical: she's solved several incidents that slipped by Reimu and Marisa, she's resourceful, she can be witty, and she tries to help others improve themselves (usually in vein, sadly).
