Angel Entry Phrase: Unknown
Date of birth: June 25, 1987

Arisu is a talented genius Angel-builder who aids her sister in creating Angels. She follows in her sister's steps as a talented Kung Fu artist, and creates very strong and agile angels. Arisu does not make Angels for herself, suggesting that she is not good at guiding them. Arisu designed Mao and Unpyo to be stronger than Suzuka, but Unpyo loses to Suzuka in record time, which mortifies her and her sister. After sabotaging Hikaru with a transmitter, Arisu is caught by Ohjiro Mihara and is told that Angelic Layer is meant to show true talent and that anyone can be brilliant, thus forcing her to give up cheating to win. She is very sensitive about the Angels she builds, and accuses her sister of not liking the Angels she made after their loss to Hikaru. Arisu creates a balance oriented Angel for herself near the end of the anime, called Alice, and vows to beat Hikaru in a friendly battle. At the end credits, in the last episode, Arisu is shown fighting the angel Queen with Alice.
