Negima!? neo

Negi Springfield is ten years old... and a powerful wizard! This boy wizard is the greatest prodigy ever to graduate from his magic school in England. After graduation, however, Negi's given an unusual assignment: to teach English at an all-girl school in Japan. Now Negi has to find a way to deal with his 31 totally gorgeous - and completely overaffectionate - students... without using magic!
