Arona is the avatar of a girl who lives in a tabletop device called the Shittim Chest. She lives in a desolate classroom in the middle of a watery expanse. She is supposed to be an assistant, but she is quite incompetent at it. Arona has a very childish personality, not very intelligent and quite gullible, often falling for jokes. She is also very sweet, innocent and cheerful. She loves sweets and can throw a tantrum if she is denied them. She also likes to draw and write poems. Arona looks like a little girl with short sky-blue/purple hair with bangs covering her left eye, a white headband with a large bow, and braids tied on her left side. She has light blue eyes, the right one with a blue pupil and the left one with a violet pupil. She wears a sailor outfit that looks like a school uniform, consisting of a blue and white top, a short white skirt, and white sneakers. On the hem of her skirt are 4 symbols that look like gamepad buttons. Her halo is a blue circle, but it changes depending on her emotions. Arona carries a rifle in the shape of a white umbrella with a sky-blue interior. A whale keychain hangs from the handle. Arona's Momochat status is "I'm always here for you, Sensei!". Her birthday is February 4th. She has a YouTube channel.
