An iDOLM@STER Cinderella Girls character in the Cool (Blue Diamond) category.
Mizuki is a former newscaster, and a calm and mature woman. As one of the oldest idols, she is somewhat self-conscious of her age. She is also the oldest to get a CD debut so far. In the anime, she hosts a game show with Totoki Airi.
As said before, due to her popularity, she was selected for the third CINDERELLA MASTER CD series, alongside Totoki Airi, Tada Riina, Honda Mio and Kohinata Miho. Her seiyuu is Touyama Nao.
