- Alice Carroll (アリス・キャロル Arisu Kyaroru?) Voiced by: Ryō Hirohashi
- Alice is an undine for Orange Planet. She first appears (in volume 3 of Aria/episode 3 of Aria the Animation) as a standoffish, snotty girl of 14. Alice speaks in a deadpan manner, and frequently uses the word “huge” (でっかい dekkai?). Although initially only a Pair, her sculling already surpasses both Aika and Akari’s—for which skill she was scouted by Orange Planet despite her age. Despite working for rival companies, Alice, Akari, and Aika often practice together, and Alice sincerely enjoys the others’ company. Because of her age and lower status, Aika often addresses her as “kōhai-chan” (後輩ちゃん? “junior” said in a friendly manner). Through her friendship with Akari and Aika, Alice lightens up as the series progresses. This does not stop her from telling the other girls to be quiet when they argue, however.
- For a long time, Alice is not confident in singing skills, until Athena advises her simply enjoy what she sings and not worry about her performance. In volume 11 of Aria, Alice graduates from middle school. She is later promoted to Prima straight from Pair, the first undine to do so, taking the name the “Orange Princess” (黄昏の姫君 Tasogare no Himegimi?, lit. “Twilight Princess”). Her name comes from Lewis Carroll, author of Alice in Wonderland.
