Rika Seo, first-year captain of Kazemai High’s girls’ kyudo team, honed her skills from middle school at a local kyudojo alongside Noa Shiragiku, their school lacking a proper club. Now leading a tight-knit trio with Yuuna Hanazawa and Noa, her composed authority earns respect, particularly from Yuuna, who openly admires her expertise. Tall with short dark brown hair, narrow eyes, and a boyish charm, her appearance sparks humorous confusion, especially when Nanao Kisaragi playfully ribs her tomboyish traits—teasing she deflects with unshakable calm. Sparingly spoken and practical, her stoic exterior thaws around large animals, subtly softening her tone.

A leader who pairs firm guidance with precise advice, her bold, direct shooting style reflects years of disciplined practice. This prowess emerged during a local tournament where she, Yuuna, and Noa secured third place with 10 out of 12 hits, earning acclaim from elite archer Nobue Saionji and proving her composure under pressure. Off the range, the trio explores shops and trends, Yuuna often introducing modern apps and fashion, their bond rooted in mutual trust—a contrast to Nanao’s antics, which Rika brushes aside with quiet indifference.

Her kyudo journey, shaped by perseverance through middle school’s lack of a formal club, fuels a steadfast drive to refine both her craft and her team’s unity. As a unifying force within the girls’ club, her role mirrors the boys’ team dynamics, cementing her as integral to their collective progress. Across narratives, her story emphasizes leadership, collaborative growth, and incremental mastery, painting a portrait of resilience anchored in unwavering dedication to kyudo.
