Ayu is one of the coolest students at her school. She is smart, studious, sporty and has just the right amount of untouchable quality to make her a friend of everybody. Her male counterpart is Kaji-kun: warm, happy, friendly and a member of the baseball club. No wonder Ayu's got a crush on him!

One day, Ayu sees a new student, Nina, crying and looking for something. After Ayu helps her find it, Nina decides to show her gratitude in the best way she knows, magic! Nina turns out to be a student from the Magic Kingdom and is currently "studying aboard" in Ayu's school!
