Why there is so much yuri between reisen and youmu if they have absolutely no connection?

There's so much yuri in Touhou in general when none of them are actually gay.

For some reason, no one needs one (reason).

I asked the same question once. The answer I was given: "It's cute as hell. That's all there is to it."

Ahh Touhou. Just pair up two random girls together and it somehow makes sense.
