At first, I just wanted to watch it for Aice5 -my favorite band-, but finally I fell in love with this anime. The only thing I don't understand is: why Mizuho's grandfather wanted him to go to this school ? I found the design very colorful and fresh, and even if the characters and the story aren't very original it's always a pleasure to watch this kind of anime. The music and openings/endings are pretty cute and fun, and the seiyuu cast is very intersting, because there are a lot of unknown seiyuu. This anime is fun, happy but not revolutionary, through there is thissomething which makes it a great anime. If you don't know what to watch and want to have fun, watch OtoBoku !!!
