When ten-year-old prodigy Negi Springfield graduated from university with a degree in magic, he never imagined he would soon be teaching English to a bevy of gorgeous high school girls. Now Negi’s old friend Chamo, a lecherous weasel from Wales, and student Asakura have arranged a competition among the girls to see which of the lovely students will be the first to kiss the teacher! Sure, a kiss will strengthen Negi’s magical abilities, but doesn’t this contest just support Chamo’s voyeuristic proclivities? On the other hand, Negi needs all the help he can get when the magical creatures of western Japan strike!
Ok. Here's what happens. There are five Negi's because the real Negi himself was trying to make a replace of himself, but made four mistake selves, and all five of them came to live, and caused havoc, making the game crazy, and the fake Negi's disappear after they have been kissed. Then the real Negi comes back, and then there's more. I'll stop there.
