Nagisa Ibuki, a second-year Hoshimi Private High School student, balances her studies with membership in Hoshimi Production’s idol group Tsuki no Tempest. Born August 3, she stands 154 cm tall, her brunette hair accented by a hot pink bow and scarlet eyes mirroring her image color. Her signature outfit pairs a navy-blue-and-white dress with pink trim, mismatched stockings, and pink-and-white heels.

Nagisa’s life orbits her friendship with Kotono Nagase, whom she met in junior high. Initially daunted by Kotono’s intensity, she grew to admire her friend’s candidness and hidden fragility, cementing a bond that led Nagisa to join Tsuki no Tempest solely to bolster Kotono’s aspirations. Though outwardly upbeat and quick to uplift others, she voices candid frustrations over dance struggles and the pressures of rehearsal.

Privately, she chronicles her thoughts in a guarded diary. Academically drawn to modern literature’s emotional resonance, she wrestles with math. Her culinary passions lean toward peach-flavored treats and morning rice-based meals, once experimenting with boiled eggplant, while bitter melon earns her disdain.

Within Tsuki no Tempest, Nagisa champions unity, likening their trio to a tripod reliant on mutual balance. She frames rival groups as catalysts for growth, not threats. Pivotal moments—dawn practice sessions where she discovered equally driven Kotono—solidified her resolve. Onstage, she prioritizes audience delight over personal glory, channeling performances into shared joy.

A childhood memory of coaxing a shy classmate from isolation echoes in her idol philosophy: forging connections through music. While initially uncertain of her path, she now defines her role by the smiles she ignites, anchoring her purpose in uplifting others.
