Recommend you to
read it !:P
Ten-year-old
prodigy Negi Springfield, has just graduated from magic academy. He
dreams of becoming a master wizard. Instead he's sent to Japan to
teach English...at an all-girls high school! All the students are
delighted with their cute new teacher--except for Asuna, who
resents Negi for replacing the teacher she secretly has a crush on.
Although he is forbidden to display his magical powers, sometimes
Negi can't resist. And when Asuna discovers Negi's secret, she vows
to make his life as difficult as possible—just the thing to prepare
Negi for the challenges of life as a master
wizard!
