Minori is a girl in Ryuuji's class, and is a close friend to Taiga. She is also known by the pet name "Minorin". In contrast to the negative Taiga, Minori is always smiling and cheerful, but is also a natural airhead, though it is suggested that her airhead ways may be a facade. She is very athletic and is the captain of the girl's softball club at school, though at the same time she holds many part time jobs. She is a glutton when it comes to food, but is also constantly combating with dieting.
Toward the end of the anime, she reveals that she also likes Ryuuji but has given up on him in order to let Ryuuji and Taiga be together.
