希野優音

笑梦的挚友，就读于敏慧学园的女学生，也是该校三大偶像之一。她对隆相当严格。她对讨厌的事物毫不留情，这也是她不太坦率的原因。她和笑梦关系很好，总是忍不住为她那无私的性格而担心。 她的人偶相当了不起，总是能完美反映出优音的情绪（以及情绪波动）。

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.
