Aoi is a sweet and cheerful person who is very close with her best friend, Nene. Although she claims to dislike scary stories, she continues to delve into them for the sake of cheering Nene up, since she knows that Nene enjoys them. Considering her zealous presentation and continued involvement with the tales, she may actually have some interest in them herself. She is shown to adore romance, as evidenced by her enthusiastic support of Nene's romantic endeavors and enjoyment of discussing crushes. Despite her continued rejections of his advances, she was also rather jealous and upset when her childhood friend, Akane, seemingly began to date someone else.

Aoi is also shown to be good with words and is able to get people to do what she wants just by using a little bit of pressure. She is especially harsh towards Akane, denying every single one of her love confessions all while smiling cheerfully.

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, and 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.

Aoi believes that Akane's feelings are directed towards her fake self and that the "real" her is not good enough for his love. Aoi feels as if she has no one to trust or rely on as all her loved ones deceive her, and no one understands nor cares for who she truly is. Ultimately, Aoi is a deeply lonely and unhappy person.
