As I said previously, I couldn't make it to the concert, but I did go to their panel. I was sitting in the front row in front of Ai. It was so awesome! Aika waved to me personally at one point. Unfortunately, no photos were allowed.
And I was pissed that I didn't get their autographs. I was too far back in line.

Someone managed to sneak a video of Morning Musume coming across the stage at their panel. You can see me in the video too! Eight seconds into the video you are can see me sit up. I was cosplaying at the time, so I have my brunette wig on, pulled into a ponytail, and I'm wearing black with two red stripes going down the back. Then a Reina fan covers me up, LOL.
