A student at Root Academy. She is one of the members of the Puzzle Club. When Airi was little, she knew how to solve puzzles; but for some reason, she can't anymore. She is also pretty clumsy, eg falling on the stairs and dropping things in the caféteria while carrying food. Just like Tamaki, she is also temporarily manipulated into being a member of Orpheus Order, and her personality changes from the clumsy, cheerful girl into princess-like. However, her Orpheus Ring breaks later when Kaito solves her puzzle. (Source: Wikipedia)
