>>8837729Mio has been released, and the not Fubuki and Chris have been put up recently. I'm guessing we'll see Chris and the other one soon enough.
An ACT-MODE thread has popped up back then, but there aren't many releases yet to really fuel it and moreso was just a Symphogear toy thread than anything.
Just pre-ordered Hibiki, actually liking the face more than the original. Looks more... Alive, I guess.
