Yuuna Hanazawa is a second-year student at Kazemai High School and an active member of its kyudo club. She sports a fluffy bob haircut, depicted in the anime as shoulder-length auburn hair typically styled in low twin-tails, with round green eyes and a petite stature.

Her personality radiates pep and trend-conscious energy, marked by a consistently friendly and helpful demeanor toward others. Yuuna shares a strong camaraderie with fellow kyudo club members Rika Seo and Noa Shiragiku, frequently acting as their vocal encourager. She openly admires Rika, declaring her the girls' top archer and "cuter than any guy" at school.

During club activities, Yuuna displays pragmatism. When the advisor proposes experienced members compete in the Prefectural Tournament preliminaries, she directly questions their readiness for the mid-May deadline. After receiving assurances, she collaborates with teammates to enter individual competitions due to insufficient members for team events.

Her interactions with male club member Nanao Kisaragi often spark clashes, reacting sharply to his narcissistic behavior and playful flirtations toward Rika. She advises ignoring his eccentric greetings and counters remarks she dislikes, though random scenes indicate their relationship remains functional.

As a veteran archer with pre-high-school kyudo experience, Yuuna resides in a modern-decor high-rise apartment.
