—Momose Rio, Online Profile

Momose Rio is new idol introduced in THE iDOLM@STER: Million Live!. She is voiced by Yamaguchi Rikako (山口立花子).


Momose Rio is a woman with a sexy body and she knows it. While she likes to use it as her weapon, the results are not as good as she hopes. According to her own words, Rio is never popular among the boys and she doesn't know why.

Although that is most likely because, while she has a very attractive body, Rio doesn't know how to charm men at all, and thus, her tactics are always too straightforward and drive men away instead. Although she has a carefree personality, like most adult idols, Rio can often be seen taking care of the younger idols.



  • Rio is close with Baba Konomi. She seems to respect Konomi, even calling her “Konomi-neesan”. That might be because they have what the other doesn't have. Konomi, despite having a childish body, is a reliable adult. While Rio, who has an adult body, lacks maturity.
