They were just on Tokuban. It was... very strange O.o Taka picked on Erika and Mai for a while, and Kanna took some special crack before the show, because she was pretty much crying on stage from laughing so much. Erika had to try and calm her down, haha.
They asked a few of them what they were scared of. From what I gathered, Kanna's scared of things under her bed, Saki said something about not knowing what to say to Tsunku, and Mai's I couldn't really catch, but something about not being able to tell which people were 'higher ranked' O.o Like, bosses and such.
Then they brought out that freaky "chikusho!" guy that was on the skits recently. Most of the girls had absolutely no idea what was going on, Maimi was the only one laughing. They performed while C-ute watched and that was about it.
Erika I think still has the best TV presence. And Mai certainly throws herself out there, but I'd say that comes from being so young and not caring. Kanna though was so nervous she laughed herself silly, kid needs to calm down
The set for the performance was pretty cool too.
