Possible volunteers?

So, I did a little pic hunting a while back, and came across an image that I liked. I had a couple of rough ideas for her, but I wasn't too sure on what to do with her. I think I have a good idea now though. Her name is Sachiko. She has a couple of pics:


And




She's going to be the perpetually sleepy type. Originally she was an Idol girl, but she got fired when she fell asleep in the middle of a live performance. Originally, there was another Idol girl who was her friend, and this girl gave her the motivation to stay awake during her performances. Then one day she disappeared(to AFW), and Sachiko lost the motivation to keep performing, despite her agents demands. She began to miss scheduled performances, and then, as mentioned, the last straw was when she fell asleep right in the middle of a live performance. She doesn't know where her friend has disappeared to, but, when she heard about bed wrestling matches in the AFW, she decided to sign up there and make some good money that way. I got more to her, but, I would like to know if anyone who has an idol girl (preferrably someone with a girl who has the same pic format) would be interested in tying their history in with Sachiko during their Idol girl days, and being that girl that gave Sachiko motivation to stay awake and sing for the masses.

The pic thing is a preference. Really all I'm looking for is a character who's also had a history of being an Idol girl.
