A character from [[Idolmaster Cinderella Girls]].

She is a very cute girl and takes great pride in this, to a seemingly [[narcissism|narcissistic]] degree. Witty and sarcastic, she has a sharp tongue and may come across as a sadist. She refers to herself as "boku", like [[Kikuchi Makoto]].

Due to her popularity, she was selected for the fourth CINDERELLA MASTER CD series, alongside [[Akagi Miria]], [[Abe Nana]], [[Hino Akane (Idolmaster)|Hino Akane]], and [[Nitta Minami]]. She is voiced by [[Taketatsu Ayana]].

She is in the unit [[Kawaii Boku to 142's (idolmaster)|]] with [[Shirasaka Koume]] and [[Hoshi Syoko]], as well as [[KBYD (idolmaster)|]] with [[Kobayakawa Sae]] and [[Himekawa Yuki]] in the anime.
