Chika Yuzuhara, once Rikuo Uozumi’s high school girlfriend, reenters his life as an adult after their youthful romance fractured when she pursued another relationship. Her reputation as the “Queen of Disaster” stemmed from an inability to reject confessions, sparking rumors and social turmoil that mirrored her chaotic music career. Impulsive choices led to repeated dismissals from bands, fostering a belief that her presence doomed groups to disband.

Jobless and adrift, she temporarily lodges with Rikuo, confronting a past marked by early independence from her family and fleeting relationships. A gifted pianist, she abandoned her passion, resisting music as a career until financial necessity pushed her to accept a role as a professional player—a compromise shadowed by her ambivalence toward the craft.

In the anime, her tall, slender frame and vivid orange hair contrast with a wardrobe dominated by purple. Tensions with Rikuo expose unresolved feelings and a shared history, yet her abrupt departure from his apartment signals growth: she prioritizes his chance at happiness with another over her own impulses, hinting at newfound emotional maturity.

Her background weaves through short-lived bands in school and university, each collapse reinforcing her struggle to commit to people or paths. Though her story leaves post-departure developments unexamined, her final acts—fleeing Rikuo’s life, tentatively embracing piano again—suggest fragile steps toward reconciling her choices with their consequences.
