Nonsense, true Touhou fans find weird hats arousing too.

and hime hair cuts...

And oversized ribbons...

And strange hair colors...

And lesbians.

If you're gonna list more can't forget gaps and peaches. Lesbians, Touhou and Gensokyo are redundant together, no need to list twice =)

Danmaku guro is also a must for G-tarded Touhou fans...
