Well, I read few things about this group! First: They're in the scene from 2014 Second: Their ages are between 19 -30 years! Third: The group is focused in debts! Yes, every member has a huge debt that she shall pay and this member graduates when she completed this pay! Fourth: If you visit the official web page and you explore the profiles you can see the debt of their members Greetings! Webpage: http://shakkin-idol.com/index.html
Theyre actually not idols anymore, but do real theatre shows by now. I was there last year for one of their theatre shows when Marie (former german idol) was still with them. It was really funny, lots of good jokes, nice roleplays and a bikini show. Can highly recommend visiting one of their shows even if they dont really do idol performances anymore!
Like I said, a theatre troupe made out of ex-idols that do theatre shows with some "idolish touch". Their name changed from "The Margarines" to "Gekidan Margarines". Gekidan means "theatrical troupe".
