Mikan is the protagonist of the story.
[1] She is an optimistic, cute, athletic, and good-nature girl, but her clumsiness lands her into trouble. She is a cheerful and energetic person, much to the annoyance of her mellow-headed best friend, Hotaru, and used to live with her adoptive grandfather in the country before transferring to Alice Academy. Later in the series, it is revealed that Mikan is the daughter of Yuka Azumi and Izumi Yukihira. She is also the niece of the High School Principal on her father's side. Her father died before she was born and her mother left her with her adoptive grandfather to protect her from the academy.
She was shocked to hear that Hotaru was moving to an academy in Tokyo for young 'geniuses' and had become upset when she only sends her one letter during the time Hotaru left. When she heard rumors that students were like slaves in Alice Academy (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. She was later told by Narumi that the so-called 'Alice' means a special power, not special academic results. At that time, Mikan didn't exactly know what her alice was.
[2]
She discovers that her alice is Nullification;
[1] an Alice which she inherited from her father, Yukihira Izumi. The Nullfication Alice can temporarily cancel out the powers of other Alices in close proximity to her. She also possesses the Stealing and Insertion Alices, which she inherited from her mother, Azumi Yuka. All of her Alices are very rare and special. In the early episodes it was stated that her Nullification Alice was unstable and worked best when protecting people she feels strongly for (i.e. Hotaru, Natsume, Ruka, etc.) However, Mikan is later able to control and utilize her powers effectively with help from her teacher, Nodacchi, and her partner, Natsume Hyuuga. At the beginning of the story, she was placed in the Special Abilities class, a class with students that have rare and uncommon Alices. Upon the discovery of her Stealing and Insertion Alice, she was transferred to the Dangerous Ability Class and forced into the Elementary School Principal's control. She is currently a Single Star, but the rank will most likely be changed to Special Star upon discovery of her Stealing Alice. Like her mother before her, her Stealing Alice caused her to receive unwanted attention from the Elementary School Principal and she becomes his favorite student. In chapter 96, she is moved to the Dangerous Ability Class by the Elementary Principal so he can gain use of her Stealing Alice, but Natsume and her friends come to her defense and help her escape from him.
While running away from the Elementary Principal, her uncle tells her the truth about her parents and birth, which shocks her. She is also asked that she leave with her mother for her own safety. She refused because she distrusted her mother for harming her friends in the Z arc. However, after looking at her mother's past and witnessing her father's death, she decides to go with her mother and realizes that she loves her mother. Unfortunately, her mother is killed by a bomb planted by Goshima as part of the Elementary School Principal's orders to prevent her from escaping and she agrees to sacrifice her freedom in order to protect the students. From chapter 140-154, she was imprisoned in the Main Building by the Elementary Principal, and forbidden to leave her room and have contact with her friends. In chapter 155, she escapes to heal Nobara and teams up with Persona to stop the ESP. In chapters 165 and 166, she uses the last of her Alice to save Natsume from dying, making her a non-Alice.
At first, she is disliked by her classmates and teachers due to her stubbornness and naiveness. She was the subject to frequent bullying, but she is always defended by Hotaru and her closest friends. Many were doubtful of her because she initially didn't know what her Alice was at first, but she gradually earns their respect as she proves herself as an Alice. She even wins over those who hated her at first, like Natsume, and becomes well-liked and popular among her peers. While she has strong attachments to her friends, she is clueless about love and romance due to her believing that she is too young to like boys. She is even oblivious of the feelings of Natsume and Ruka, and thought of them as friends. When she met Natsume, she hated him due to his cold and perverted attitude, and was appalled that Narumi had chosen Natsume to be her partner. However, as she gets to know him, she realizes his problems and comes to care for him, and eventually falls in love with him. She doesn't realize her true feelings, even though she has her first kiss by him at the end of Chapter 50, until chapter 134, when she feels Natsume's feelings and confesses to him. In chapter 144 and 145, she and Natsume directly confess their love to each other, and accepts Natsume's proposal. In chapter 166, in an attempt to save him from dying, she sacrifices her Alices. Soon after, her memories are erased and she is returned to her village.
