Mashilo leaving Hearts for DEEP GIRL and Yuyu leaving DEEP GIRL to stay in Hearts made sense from what little I know of them. Went to a free DEEP GIRL event in Shibuya and they were doing some pretty sleazy things for the sake of a late night TV show they were filming. Example: writing hiragana on the back of the member in front of them using their tongues and having to guess which one it was, kind of like the game "telephone". That sort of thing seems more like Mashilo's style if you have seen the pictures she tweets or posts to CHEERZ. Yuyu seemed pretty uncomfortable with the whole experience. I think if you buy 1,000 or more copies of DEEP GIRL's 2nd single, you can go out on a date with one of them.
Oh, I remember seeing that list for their first single.
Hmm, found the list for their 2nd single:
http://www.deep-girl.com/news/0/26686/100 CDs is a one-to-one satsueikai with one member for one hour. Which is a damn lot more expensive than solo satsueikais with members of other groups which offer them...
300 CDs is a two-hour lunch date
500 CDs is a four-hour date in Shibuya
1000 CDs is an all-day date in Disneyland.
The number of CDs seems so ridiculous to me, that I wonder if anyone actually bought any of those things for their 1st single, and whether anyone would for their 2nd. Just seems like a way to drum up PR.
