Negima! Volume 31 — Ken Akamatsu

10-year-old Negi Springfield has just graduated from a British school for wizards. After meeting with the school headmaster to discuss his graduate work assignment, he finds that he will be moving to Japan--to teach English at an all-girls high school. Under strict instructions not to show his magic powers, Negi finds that he can't resist using them to help others. Of course, despite his good intentions sometimes his magic just makes things even worse!
