Aria has puffy tea green hair, the ends tied in pigtails with blue ribbons with a flower in the center. The pigtails separate into two strands curling around each other. Aria wears one pink flower accessory on each side of her head, and she has lilac eyes.
Aria is a pure-hearted girl described as being an "overwhelmingly fairy-like idol".
Aria was born into a large family and grew up in the lush natures of Finland. A prodigy, her performances are said to be like seeing an aurora.
- Aria has always admired Hime ever since she was a child, and believes that her love for Hime is more than anyone else. Hime considers her to be Aikatsu's heaven-sent child, describing her stages as "aurora-like". After inviting her to Japan, Hime later then passes on her brand, My Little Heart, to Aria.
- Yume and Aria first met when Yume was training. Aria appears to enjoy being with Yume because of all of the experiences she gathers upon being with her.
- Kirara was the first Venus Ark student that Aria got to know on personal terms. As such, both of them are on friendly terms with each other, and are often seen together on board Venus Ark.
- Elza scouted out Aria and invited her to join Venus Ark. Aria accepted her offer mainly because she wanted to know more about different types of Aikatsu and expand her own horizons. She is shown to respect Elza as well, offering the latter a carnation flower in return for accepting her.
