Akira is a cute Junior High School boy who has a great singing voice that his sister is always raving about. She thinks his voice sounds like an angel's and in a truly sister-like fashion, she plots to get her younger brother into a dress and wig so she can see him look like an angel while he sings too. So at home one day after school, she gets Akira to sing karaoke, and then dresses him up in a frilly dress and a wig of long hair!

Nearby, a talent scout hears a beautiful clear voice. He follows the sound and can hear Akira's singing coming out of Akira's house. He is thrilled to see the voice belongs to the girl in the cute dress. But Akira tears the wig off and insists that he is a boy. After a moment of thought, the talent scout begs to recruit Akira to be the next new FEMALE idol singing sensation! Akira refuses at first, but finally relents when he realizes he may get the chance to meet Ruri, a currently popular female idol singer. And thus "Mizuki" is born, the angelic new GIRL idol singer! Watch the fun as Akira attempts to be a female idol, and is surrounded by girls who like him or hate him in his various identities!
