Kino Yuune

Emu's best friend, a female student attending Minkei Academy, and is one of the three great idols there. She's pretty strict toward Ryuu. She doesn't hold back against things she doesn't like, that's also the reason why she's not very honest. She's on good terms with Emu, and can't help but get worried about her altruistic personality.
Her doll is pretty awesome, it perfectly reflects Yuune's mood (and mood-swingings) all the time.
