In contrast to her age, Akari's voice and overall personality both resemble a little girl, sometimes even compared to a baby; she is a cheerful, innocent, emotional, competitive, and sometimes mischievous and clumsy person who loves video games. From her own self-description in her debut stream, she describes herself as being noisy, shy around strangers, involved, curious, troublesome, moody, as well as a person who likes doing things at her own pace and hates losing.
Part of Akari's charm is that, like a child, she always appears to act and express her emotions quite naturally, and that she behaves freely. When particularly happy or amused she tends to clap her hands, and when praised her smiles are expressed quite clearly through her model. Conversely, this also leads to her being referred to as a kuso gaki, due to her tendency to be quite frank when she gets mad and her habit of teasing and provoking the people that she's close to.
In spite of her "baby-like" image, she is, true to her self-description, involved, and often takes charge in organizing collabs such as Idios collabs and full-party lobbies and customs for. In another contrast to this image, she is known for her high gaming IQ and her ability to adapt fairly quickly to any given game she plays. She also dislikes being treated like a baby, and aspires to become a "sexy onee-san boing boing"-type girl.
