Aichan's actually the last person I'd imagine stumbling and falling on stage but then again, the stage designs have been getting more and more elaborate with steps and whatnots so it was just a matter of time someone as graceful as she is would suffer the same fate (fortunately, not as bad) as Tsuji.
On tours she eventually transforms into a sweaty sex demon.
Wah the part about her not moving when Risa called her sounded really scary but I'm not it doesn't seem to bad since she was about to make it back to one of the concerts. Hopefully she'll recover quickly.
Anyway, I hope she's taking it easy, we don't want to force that precious ankle
Listened to the concert recordings. it was so touching to hear Ai chan and Risa crying during aruiteru. Risa cares so much about Ai chan. It's a good thing she seems fine on the most part.
