That's disappointing to hear one of the two girls (Chaki) leaving AAA. We're sad to hear about this, but I'm backing this departure. It would be too much to bear if she has a baby and she is part of AAA at the same time...we're going to really miss her from AAA.
So, that means, only one remaining girl in AAA? They will never be the same without Chaki (Ito Chiaki)...
