Kumiko Oumae ends up with Shuuichi Tsukamoto.
Kumiko Oumae's Romantic Path
Throughout the Hibike! Euphonium series, the relationship between Kumiko Oumae and Shuuichi Tsukamoto is a recurring element. Their bond develops from childhood friends to a deeper, more romantic connection as they navigate their high school lives and musical aspirations within the Kitauji High School Concert Band.
Evident Confirmation
The resolution of their relationship is strongly implied at the very end of the series. During the post-credits scenes, a significant timeskip occurs. In these scenes, Kumiko is visibly seen wearing a distinctive sunflower hairpin. This particular detail serves as a strong visual cue, implying that she and Shuuichi Tsukamoto are indeed together, confirming their implied romantic future.
