Ami Futami  

, 双海 亜美

A set of two sisters, Ami and Mami, who together form an entertaining singing duo. They both enjoy doing impersonations and joking with their friends. While Mami appears to be more mature than Ami, it's important to note that she is actually the younger sister. The only way to distinguish between them is by looking at their hairstyles - Ami ties her hair on the right side while Mami does so on the left. As a fun experiment, they sometimes switch their hairstyles and perform as idols under Ami's name. Only those within 765 Production are aware that Ami is actually a pair of twins.
