    @kougeru: I know, that's what I like about seiyuus. Their vocal ability are always amazing and they barely do lipsync on a live event :D

    Kiranaw lol. Sphere isn't Sphere without ALL the girls. Besides, Ayahi is the freaking hottest one, AND the "best" singer (in a classical manner, I quoted because everyone will have different tastes but she is best on a technical level if you listen to her solo work).
