Sumire Okuyama is a member of the IDOLY PRIDE unit TRINITYAiLE. She is a student at Benibana Middle School and her image color is light yellow.

Sumire is a former child prodigy actor who seems too mature to be a junior high school student. She commutes to school from her parents' home in Yamagata Prefecture, but she doesn't mind the difficulties she has endured and she is always smiling. She usually has a middle school-age spirit, but when she is not careful, she has a tendency to speak in a dialect.

After a successful audition, high school student Kotono Nagase and her best friend move into a dorm with eight other aspiring idols. They quickly realize it takes more than cute choreography and cute outfits to reach the top—it will take blood, sweat, and tears to advance in the idol-ranking VENUS program, where the top spot is held by superstar Mana Nagase…who happens to be Kotono’s older sister.
