Shy Ayu Tateishi has just made a new friend at school. But this new friend, much to her surprise, is no ordinary classmate. Nina Sakura may look like a normal middle school girl, but she's got a big secret. She's a witch. Or, rather, she's studying to be a witch. And, apparently, she's not doing her homework. Her spells are devastating in their ineffectiveness and often result in the most embarrassing situations for poor Ayu. But things wouldn't be so bad if Nina's sorcery didn't make Ayu look silly in front of the one boy she secretly adores. All she wants is a simple love potion. What she gets, however, is a new best friend who almost flunked out of witch school!

Nina Sakura isn't exactly your typical teenage girl. She's actually a transfer student from a witch school in another dimension. Now living in Japan, Nina is hoping to improve her GPA, make some new friends and spin a few love spells for her unsuspecting new classmates.

But being a witch-in-training isn't as easy (or fun) as it seems. In fact, it's sort of a pain in the neck. There are secrets to keep, all kinds of tricky magical stuff to remember and never-ending catastrophes to sidestep. Nina may be sweet, but she's got a lot to learn. Thank goodness one of her schoolteachers is an émigré from the Magic Kingdom. Two witches are better than one, right? Well...maybe not.

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!"
