Who is Midoring and what is her connection to Ayu?

[ストロボ・EdGE]

Well, I'm a pretty new fan compared to most people here so I'm not familiar with her dancers and her entourage and what not so... just who exactly is this Midoring? She's Ayu's dancer, right?

I searched to see if there were any threads about her and there weren't so maybe people who know a little more can like tell me about her? I'm not talking about her sexual orientation or any romantic links with Ayumi or anything but maybe a profile or a small biography of some sort? If there are any links in Japanese that you have that would be fine too.

Thank you~
