Mikan is the protagonist of the story. She is a cute, energetic, good-natured girl, but her clumsiness lands her into trouble. She is a very up-an-at-it and athletic person, much to annoyance of her down-to-earth friend, Hotaru. She used to live with her grandfather in the countryside.
She was shocked to hear that Hotaru was moving back to the city to go to an academy for young 'geniuses' like her. When she heard rumors that students were like slaves in Alice Academy (which she felt was a possibility, since they gave money to parents for sending their children to the school), Mikan left her grandfather and her home to go after Hotaru by herself. She was then accepted to Alice Academy by Narumi-sensei and could attend Alice Academy with Hotaru and many other children with extraordinary powers.
Her Alice is Nullification, which can resist the effect of Pheromone type Alices and completely negate the powers of other Alices in close proximity to her.
