This is when Arisu was at Alice Academy. Yes I know that International Academy is overlapping three different ideas in the story. UTAPRI, Gakuen Alice, and an own idea (who, what, when and where International Academy is taking place). Sorry for doing this to you guys. There are a few mentions, or inferences, about her time at Alice Academy(Gakuen). So I wanted to put this up to explain a few things about her.
In Arisu's Adventures at Gakuen Saotome the first, in a way, inference is in Chapter 6: Backstage Passes. It's at the point where she's describing her old school.

Bio: Arisu has been going to Alice Academy ever since her father found out that she had the type of Alice of pheromone. She was always adapting to new situations and finding very creative ways to solve every situation she's been in. Arisu has always been way above average. When Arisu arrived at Gakuen Alice, Narumi noticed something familiar about her and took her under his wing. (From her Arisu Fujioka Profile) Arisu is a daughter of a maid of the Jinguji family. Arisu's mother died when she was very young. Her father has been taking care of her besides his own children. Arisu doesn't quite actually know yet that her father has a son. Arisu has been kept a secret from the workers and anyone she has been kept a secret from anyone else she has come in contact with. So Arisu has taken her mother's last name instead of her fathers' last name. Arisu has been composing and singing since she was a little girl. Ren has taught Arisu some of what she knows now. He has taught her how to play the saxophone. She has always looked up to Ren. To Arisu Ren is her idol. She wants to compose for him if she doesn't make it as a singer.
Personality: Arisu is shy, at first, when meeting new people. She's knowledgeable, interpretive, and a musical genius. Arisu is a very outgoing girl once you get to know her. She loves making new friends. Arisu is very intelligent. Arisu is a happy go lucky person. She never really was an outgoing person when she was young, but she became a little more open when she attended Gakuen Alice. (Changes when she goes to Gakuen Saotome. And then changes back in International Academy.)
Appearance: Arisu has light brown hair and light blue eyes that resemble the sky. She mainly keeps her hair up in a ponytail. Sometimes Arisu will have her ponytail in a braid. Arisu did cut it when she was in sixth grade, but then decided to let it grow out again.
Likes: Arisu likes to listen to Ren playing his saxophone. She loves falling asleep to the sound of a sax. Although she hasn't heard him play since she left him to go to Gakuen Alice. She loves to write. Arisu has written something from lyrics to a song to a little short story. Arisu has a couple bookshelves in her dorm room with a couple rows on each shelf. There are also a few sketchbooks lying around the room.
Dislikes: Arisu can't think of a world without music. Music is her life.
