I've only just found out about Berryz Koubou *better late than never* and I must say Miyabi caught my eye. However...what is she like? I mean her character...hyper? funny? please tell me
I'll be more than happy to tell you about my second favorite Berryz

As you may have noticed Miyabi gives off the image of a very "cool girl" with her long face and often serious expressions in photos/PVs/live performances. Combined with her excellent singing ability (listen to just about any Berryz song) and slick dancing ability (best exemplified in Jiriri Kiteru) this image is in some ways very fitting of the composed ace performer.
But if you watch a lot of the backstage DVDs or DVD magazines you'll see that Miyabi is in fact an adorable GEEK. She has a really whacky sense of humor (watch the Berryz DVD magazine Volume 5; I swear that girl was as high as a kite!) that dumbfounds other members and a child-like level of energy that seems on par with Momoko at times.
There's only one negative I suppose; I think there's a potential for her to be a little mean or domineering to the other members. There are times when it seems the other members don't really get or appreciate her antics and Miyabi can be a bit insensitive to their feelings (see backstage DVD footage for the Natsu concert and DVD magazine Volume 5 as well).
So there you have it; actually the most interesting Berryz overall, IMO, as well as arguably the best singer and dancer. You know after writing this all out I've realized that she's actually tied with Yurina for my favorite Berryz
