Mami Futami  

, 双海 真美

Two sisters, Ami and Mami, form a singing duo with their playful personalities and love for doing impressions and teasing friends. Although Mami appears more mature than Ami, it's actually the other way around since she is younger. The only distinguishing feature between them is their hairstyles - Ami ties her hair to the right while Mami does it to the left. As idols under Ami's name, they switch hairstyles and entertain audiences. Only those within 765 Production know that Ami is actually a set of twins.
