Futami Ami (双海亜美 - ふたみ あみ) is one of the main characters of the Idolmaster series.
Elder twin of fellow idol Mami, she is distinguishable from her twin sister by her right-facing side ponytail and, in later series, shorter hair. The playful 12-year-old Futami twins love doing impressions and teasing their friends, and would 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.
The twins' theme color is yellow, and are voiced by Shimoda Asami, also known as the voice for Vocaloid's Kagamine twins, Len and Rin.
