One of the main characters of the Idolmaster series. Elder twin of fellow idol Futami Mami, distinguishable by her right-facing side ponytail and, in later series, shorter hair. The Futami twins love doing impressions and teasing their friends, and frequently use their identical looks to take turns performing as a single idol (under Ami's name). Ami is also a member of the Ryuuguu Komachi unit.
