Mafuyu Kurosaki, a former delinquent with a strong sense of justice, exceptional fighting skills, and a dense head, has to start anew as a proper citizen and attend Midorigaoka Academy under the threat of disownment. Beyond adapting to a new school, Mafuyu has to get used to living alone, as the dorms are full. With limited funds, the inability to make even a cup of instant noodles, and a big dream of becoming "an ultra-shiny female high school student," things aren't easy.
This dream is difficult to achieve because Mafuyu's sense of style is uncouth, and trouble seems to find her no matter where she goes. Making matters worse is Takaomi Saeki, her unorthodox homeroom teacher with barely legal methods, and Kaori Hayasaka, her first new friend, who is also a delinquent classmate.
Through hilarious situations, misunderstandings, and exciting action sequences, Oresama Teacher follows Mafuyu's adventure as she strives to become a normal feminine girl while still being true to herself.
This volume also includes the one-shot "Omae Watashi no Koto Suki daro" (Do you like me?).
