MARIA performed at least 2 more songs at their lives: Hachake and Tsubomi, I wouldn't be surprised if they had more in their sleeve.
Also, at their staff's blog it says they've rushed to work at 2nd single!
btw, who is everyone's favorite member? To make it more interesting, let's exclude Maiko who's obviously the reason you've noticed the group. So, mine's Ayuka (the blondie) :mrgreen:
