Ultra Maniac, Volume 4 (Ultra Maniac #16-17)

Unfortunately, Nina is finding out that going to school on Earth is a lot more complicated than she first thought. Not everybody is glad to have a spunky (and cute) witch flitting about campus. A girl named Sayaka, for example, has recently become obsessed with Nina. A half-witch herself, Sayaka is jealous that her new classmate is stealing all the attention away from her. Like they say in the Magic Kingdom, "There's no fury like that of a teenage witch ignored!"
