Mahou Sensei Negima! is the newest OVA's. Based from the Hybrid anime manga Negima!, Negima!? and Negima Neo.
Negi Springfield has just graduated from a magic Academy in Wales, and finds that his assignment for earning his full magic license is a job as a teacher — in a private all-girl's school in Japan.
And life doesn't get any easier. Although he's supposed to keep his magic secret, he's having control problems, and blows his cover in front of some of the girls almost immediately. Furthermore, he can't get properly licensed until he finds a partner.
