Aqua is a short girl with long purple hair in a maid outfit.
Aqua is a bumbling airhead who somehow manages to become the victim of every joke in which she gets involved. She is also childish and prone to throwing tantrums, smashing her keyboard, and hyperventilating when things don't go as planned (which is most of the time). She enjoys playing pranks and causing mischief, but it almost always backfires because of a combination of poor planning and bad luck. To make matters worse, Aqua makes no attempt to avoid embarrassing situations to the point at which many wonder if she might actually be masochistic. She has asked other Hololive members, including Uruha Rushia, to bully her on several occasions.
She is a virtual maid who wears a marine-themed maid uniform and a white mob cap decorated with an anchor. She has purple hair (resembling a red onion), with twin spiral ponytails decorated with navy-blue ribbons. She also has a few streaks of light-blue hair in her bangs and the inner edge of her ponytails and a light blue ahoge.
Although her initial image may paint her as childish and a crybaby, Aqua is extremely resilient and will stop at nothing to reach her goal, especially in gaming. She often does very long endurance streams to complete the challenges she places on herself. She is also shown to be very mechanically skilled in a competitive games being one of the best Smash and Apex players in Hololive.
According to Aqua she joined Hololive when she was very introverted and wanted to be more social with other people. She auditioned for Hololive without knowing really what it was.
Aqua has been noted by other members of hololive as being particularly slight, short, and petite in terms of stature. During Aqua's Wii Fit stream, in addition to revealing her height to be 4 feet and 10 inches (148 cm), she accidentally revealed her weight to be a mere 95 pounds (43 kg).
She's playful in bed, but when push comes to shove she's submissive.
