I voted for Mio-chan, of course, however, her fans can be really annoing, par example:
ME: I'm buying a new bass guitar.
RANDOM MIO FAN: Yeah, I'm also Mio's fan.
And somehow even people who know I play bass since middle school tend to say that...
And worse yet, I wanted to buy Yamaha but now I'm really thinking about Fender.
I've read, by the way, that Fender's sales in Japan went sky high lately, espetially the Lefthanded Jazz '62 Sunburst is selling well- Japanese otaku must be really hardcore...
