I can definitely see why it'd be hard to find an Ayu in your area o___o Ayu cosplay is indeed rare these days, and the few I've seen have been based in California. (More J-music fans there in general, probably.) I do know a few Cosplayers here in Texas but we're all pretty spread out... I doubt I'll find a Yo-chan or any other Ayu cosplayers here without getting them into Ayu music myself, haha
