Nina Yamada is a junior high 7th grader who dreams about a boy who is strong, handsome, and kind enough to protect her. One day, Nina "accidentally" swallowed a Crystal Pearl that she assumed was a candy. But the Crystal Pearl was the goal of a sorcery examination. Nina is the new Crystal Pearl which is targeted by many probationer sorcerers and goes on for half a year. During this whole mix up, she meets two magician boys named Zero and Ichi and comes to a conclusion that they can protect her until a potion is made to remove the Crystal Pearl from her. However, this potion will take about 6 months to complete. Even at school and at home, Zero and Ichi protect Nina where ever she goes. Now, not only is Nina being attacked and chased around by a group of magicians, but she has to figure out which of her two protectors she likes most!

Junior high schooler Nina is ready to fall in love. She's looking for a boy who's cute and sweet and strong enough to support her when the chips are down. But what happens when Nina's dream comes true…twice? One day, two cute boys literally fall from the sky: they're both wizards and they've come to the Human World to take the Magic Exam. Their success on this test depends on protecting Nina from evil, so now Nina has a pair of cute magical boys chasing her everywhere she goes! One of these wizards just might be the boy of her dreams…but which one?
