Michie Matsumoto (松本 美知恵 Matsumoto Michie?) is a supporting character the Hibike! Euphonium series. She is Kumiko, Sapphire Kawashima and Hazuki's teacher. She serves as the assistant band director of the Kitauji Concert Band. Michie is a tall woman in her fifties (though she could be mistaken for younger, despite having age marks), with cropped, soft black hair and sharp, violet eyes. She dresses professionally; wearing a white dress shirt - a purple blouse underlying it- white heels, and light gray, capri-cut slacks. Regarded as the school's severest, sternest teacher, Michie has shown to be quite strict with her class, especially the girls; in the first episode demanding that two female students who shortened their skirts pull them back down to their original length.
