Sakura Kitaōji, a first-year student at Starlight Academy, emerges from a prestigious kabuki theater lineage, her reserved demeanor belying a heritage steeped in traditional Japanese arts. Rigorous childhood training instilled a unique hereditary trait—the "Kitaōji Theater"—triggering involuntary theatrical performances during emotional surges, intertwining comedy with her struggle to reconcile family legacy and personal identity.

Initially timid and isolated, she navigates self-doubt under Ichigo’s mentorship, forging friendships that anchor her burgeoning confidence. A transformative breakthrough arrives with the Aurora Fantasy Premium Dress, a symbol of childhood reverence tied to a beloved picture book author. Confronting the brand’s designers, the enigmatic Green Grass twins, she claims the secretly crafted dress, cementing her resolve to transcend insecurity.

By her second year, Sakura evolves into a poised leader, steering the unit Powapowa-Puririn alongside Otome and Shion. Their relaxed synergy propels them to academy prominence, culminating in a televised platform and top-tier status. Her speeches at graduation ceremonies juxtapose heartfelt vulnerability with hard-worn assurance, mirroring her ascent from hesitant idol to influential figure.

Crowning her trajectory, Sakura secures the Starlight Queen title after a high-stakes face-down against exchange student Miyabi Fujiwara, merging traditional kabuki flourishes with modern idol flair. Balancing Powapowa-Puririn’s collaborative spirit with solo ventures, she epitomizes adaptability, her legacy reflecting both collective ambition and individual grit.

Key bonds shape her journey: unwavering respect for Ichigo, playful camaraderie with Otome and Shion, a shared passion for Aurora Fantasy with Maria, and a rivalry-turned-partnership with Miyabi that bridges performance eras. Familial tensions ease as her twin brother Sakon shifts from opposition to steadfast support, echoing her reconciliation of duty and dreams.

Quirks anchor her authenticity—a palate favoring matcha and wagashi, a reflexive "-sama" formality, and an aura blooming with pink-yellow sakura petals, a nod to her namesake. The Kitaōji surname, evoking Kyoto’s cultural heartbeat, underscores her rootedness. Whimsical touches, like numerically named koi (Koi-ichi to Koi-jū) and pioneering non-primary brand coord performances, layer charm onto her storied path.
