Kawashima Miyuki (川島幸)

As we are currently having a discussion in the main H!P Egg/Kenshuusei thread, I thought that it would be a good idea having an own thread for Miyuki as some things have been discovered about her recently.

Name: Kawashima Miyuki (川島幸)
Nickname: Miyuu
Birthdate: August 26, 1986

She used to own an Ameba blog, [ http://ameblo.jp/happiness826/ (her entries were visible for friends only) ]
In her Ameba profile she listed her marital status as "married", making her the first married former H!P Egg ever (status of September 2016: Aoki Erina has meanwhile married aswell).

She took part in the AKB48 3rd generation audition in 2006, but failed to enter. Up to now it had widely been rumoured that she graduated from H!P Egg to focus on studying at a university.

Today I was searching more things about Kawashima Miyuki and I've found that she in 2006 auditioned for AKB48's 3rd generation, but failed to enter. (it says former Hello!Pro Egg after her name).

Could this mean that she graduated Hello!Pro Egg to be elegible to enter other idol groups auditions?
