There is a vampire stalking the night! Normally, ten-year-old teacher/magician Negi Springfield would have no problem dispatching such a villain, but this vampire has a magic-enhancing partner - and worse, the vampire is a student in his own class! Now he must find a partner of his own, but with a class full of beautiful girls all vying for the position, it won't be an easy task. Add in Negi's old friend, a skirt-chasing, wisecracking weasel from Wales, and the nice, orderly chaos of Negi's life turns into a hilarious melee of sirens and sorcery.
