Aoi is a sweet and cheerful person who is very close with her best friend, Nene. Due to her looks, Aoi could be considered the queen of popularity in Kamome Academy, as a female counterpart to Teru. She gets confessed to left and right but easily rejects all her suitors. Aoi's true personality reveals her to be a person who looks down on others, as stated by Akane. Despite this, Aoi doesn't have a high opinion of herself either, or puts up a constant mask of perfection in an effort to be liked. This backfires as she comes to believe that others will only be disappointed when they learn of her flaws, causing her to become bitter and resentful towards all her classmates, and forcing her to suppress all her negative emotions and traits in fear of being ostracized.
