Sharaku Kobayashi (小林写楽) is one half of FLOPPY. He's on vocals and is also in charge of programming.
Sharaku has a rather unique voice. I don't think it's a matter of "vocal style" because he sounds like that when he's raising his voice too. (That's rare off-stage. He's very soft-spoken.) He sounds a lot like a cat. Cute.
He bleaches his hair platinum-blonde and he's far too tall for such a shy man! He won't let Toda write lyrics, he claims to have trouble singing words he can't relate to, but then there's the songs about being a robot...
He probably believes machines have souls. (To be honest I do too, so he's forgiven.)
