Movie
Description
Reina Kōsaka is a dedicated trumpet player with dark blue hair, violet eyes, and a height of 1.58 meters. She attended Daikichiyama Middle School before enrolling at Kitauji High School, carrying a serious, driven personality marked by an intense dislike of mediocrity and an unwavering refusal to compromise her musical standards. Her cool, unapproachable demeanor leads some peers to perceive arrogance or disrespect, though this stems from disciplined practice and a pursuit of exceptionalism rather than superiority.
In junior high, conflict arose with classmate Kumiko Ōmae when Kumiko dismissively questioned Reina's frustration over failing to reach the Nationals, asking, "Did you really think we could make the Nationals?"—an incident that seeded initial tension. Reina's belief in meritocracy defines her actions, such as audaciously auditioning for a solo trumpet part as a first-year at Kitauji. She secured the role over third-year Kaori Nakaseko through superior skill alone, causing band friction but upholding her principle that earned ability requires no apology.
Reina forms a profound connection with Kumiko, identifying her as a kindred spirit who understands her worldview. She insists Kumiko address her by her first name, cementing their bond. Their relationship peaks during shared moments like a festival date atop Mount Daikichi, where they confide personal futures and aspirations. This closeness contrasts sharply with Reina's indifference to social popularity or superficial ties. Simultaneously, she harbors romantic feelings for the band's advisor, Noboru Taki.
During her second year at Kitauji, depicted in *Sound! Euphonium: The Movie – Our Promise: A Brand New Day*, Reina maintains her musical excellence while supporting Kumiko, now a section leader navigating new responsibilities. A pivotal summer festival scene reunites them at Mount Daikichi after Kumiko's awkward encounter with her boyfriend, Shūichi Tsukamoto. There, they discuss looming uncertainties about their futures as third-year approaches, reinforcing their mutual reliance. Throughout, Reina's commitment to her trumpet—a cherished gift from her parents during junior high—remains unshaken.
