Character in Yahari Ore no Seishun LoveCome wa Machigatteiru. A first-year (and later second-year) student at Soubu, as well as student council president thanks to the machinations of Hikigaya Hachiman. Later a fixture among the Service Club members.
Iroha has shoulder-length brown hair with bangs (also depicted as blonde at times) medium sized breasts, and brown eyes (again at times depicted as yellow). Hachiman claims that her personality is as rotten as his, which she constantly ends up proving right. She also has a sort of rivalry with Hikigaya Komachi, who she refuses to call by name.
Her Sobu High School Uniform consists of a white collared shirt, pink cardigan, open black blazer, red neck ribbon, black thighhighs, and a plaid pleated skirt.
