Ayu Tateishi

Ayu Tateishi is a 8th grader that happens to be one of the most popular girls in school. Not only is she the best at tennis in the girls' club, but she's also seen as a calm and collected upperclassman who always knows what she's doing and is always classy and perfect. However, this is not the case. She can be seen breaking out of her shell as the series progresses, specifically when she befriends Nina Sakura, a young witch exiled from the Magical Kingdom in search of the 5 Holy Stones.
