Satowa Hozuki, a koto prodigy groomed within the esteemed Hozuki dynasty, carries the weight of centuries-old musical tradition. Her childhood revolved around relentless tutelage under grandfather Reiji Hozuki until his passing, after which mother Chiharu—crumbling under the Hozuki Group’s pressures—morphed into an abusive figure. The family severed ties when Satowa’s attempts to reconnect through koto performances were misconstrued as insubordination, casting her into exile. Determined to validate her artistry beyond dynastic prestige, she joined Tokise High’s Koto Club, vowing to transform its ragtag ensemble into national contenders. Initial clashes with members stemmed from her icy professionalism colliding with their untrained enthusiasm. Though gradually assuming a mentorship role, her intuitive mastery of the kato often clashed with the need for teachable methods, leaving gaps in instruction. Healing emerged through dual catalysts: a soul-baring performance at the National Preliminaries that thawed Chiharu’s resentment, restoring Satowa’s hereditary status, and her charged dynamic with brash clubmate Chika Kudo. What began as sparring disputes softened into reciprocal admiration, then crystallized when she bodily shielded him from danger, shouting her love unabashedly—an act defying both physical peril and emotional barricades. Petite-framed at 158 cm with obsidian hair and precision-tied uniform, Satowa wields diligence as both weapon and armor. She strategically feigns helplessness to manipulate outcomes yet genuinely stumbles through casual interactions, earning the “koto-baka” moniker for her artistic obsession juxtaposed with social clumsiness. Her world orbits around savory monja cravings, disdain for cold rice, and the tension between inherited excellence and hard-won camaraderie. The dissonance between solitary virtuosity and collaborative growth forms her core narrative—a prodigy learning that kinship and love, like koto strings, require harmony over dominance to resonate truly.
