You know, I'm convinced that the poeple we see as dumb are actually genious evil masterminds that have everyone fooled with their innocent act. Take Yui and Nono for example. Both don't seem like the sharpest tools, one is a certified Bakajo and the other's breasts prove her dimwittedness, right?
Wrong.
Yui is actually the person pulling the strings in Biyuuden, subtly manipulating ever action that's taken, from the song writin to the PV production. She just can't decide what she looks best as, girl or bunny...
And Nono? We'll have to wait and see how successful her newest plot is, after she ingeniously got rid of the one person that could ever possibly hold her back. Poor Aibon.
