OVA
Description
Hanayo Koizumi enters Otonokizaka High School as a painfully shy first-year with short brown hair, dark purple eyes, and a slender frame. Her signature glasses later give way to contacts during idol performances, while her green image color—representing growth and calm—pervades her merchandise and concert penlights.

Born January 17 under Capricorn, the 15-year-old shares a warm home with parents and grandparents. Her mother’s past as an idol ignited Hanayo’s childhood fascination with the profession, though crippling self-doubt silenced her aspirations. She leaned heavily on lifelong friend Rin Hoshizora, often letting Rin steer decisions.

Two passions shatter her reticence: school idols and food, especially rice. She morphs into an animated expert when dissecting idol performances or clutching oversized rice balls, fretting about weight yet devouring meals unapologetically. This duality—timid observer versus fervent enthusiast—anchors her character.

μ's formation sparks her transformation. After Rin coaxes her to their debut concert, Hanayo yearns to join but needs forceful encouragement from Rin and Maki Nishikino to audition. Accepting her place in μ's marks her first victory over insecurity.

As an idol, Hanayo battles shyness through vocal drills and mediates conflicts between peers. She mirrors Rin’s past support by nudging Rin toward embracing femininity. Though tearful during emotional group milestones, her resilience grows, yet her gentle core remains.

She tends the school’s alpacas and inherits leadership of the Idol Research Club. Her hobbies—drawing, origami, idol trivia archiving—complement a devotion to Japanese cuisine, exemplified by her quest for rice during μ's New York trip.

Solo songs like "Nawatobi" tribute Rin’s unwavering friendship and shared growth, while "Kodoku no Heaven" echoes Hanayo’s early struggles with unspoken longing. Graduating with μ's finalizes her journey from hesitant spectator to assured performer, openly celebrating her passions.
