Michie Matsumoto, assistant band director at Kitauji High School, collaborates closely with Noboru Taki. A tall woman in her forties, she carries herself with authority, her cropped black hair and piercing violet eyes accentuating a polished appearance marked by crisp white dress shirts layered over purple blouses, light gray capri-cut slacks, and white heels. Renowned for her exacting standards, she rigorously upholds discipline, insisting students comply with uniform codes down to precise skirt lengths.

Her professional ties span generations, linking her to both Noboru Taki’s father and Reina Kousaka’s father—former Kitauji band directors whose legacies inform her role as a connective thread between the ensemble’s history and its current trajectory. While offering Taki steadfast guidance and sharing collegial moments at events such as the Agata Festival, her watchful presence subtly shifts during Kumiko Oumae’s third year, as she monitors the band’s rigorous march toward nationals. Witnessing their gold-medal triumph, she sheds tears of pride beside Reina, her emotional release underscoring years of quiet dedication. Later, she honors the graduating class by planting a cherry tree, its blossoming branches mirroring her faith in their unfolding potential.

Privately, she balances motherhood—raising a daughter and son—with a fondness for Takarazuka Revue performances and culinary preferences favoring bamboo shoots and mizu yōkan, though she avoids popcorn and peanuts. Her name, blending meanings of beauty, wisdom, and benevolence, echoes the disciplined yet nurturing ethos she embodies. Though seldom central to pivotal events, her enduring stewardship remains a quiet cornerstone of the band’s institutional continuity.
