Alisa Bannings is a minor character of the Magical Girl Lyrical Nanoha series. Best friends with Nanoha Takamachi and Suzuka Tsukimura, Alisa is the daughter of two successful company owners and has plans of succeeding them. Alisa was adapted from the character of Alisa Lowell in Triangle Heart, but besides being a living being, is much friendlier and holds no such grudge against the world.

Alisa is an outspoken, dog-loving Anglophone and multimillionaire heiress. She gets angry at Nanoha halfway through the series for keeping secrets from her friends. Despite this, she cares deeply for her friend. She is a strong-willed person the apparent leader in her small circle of friends. When she has bursts of rage at not fully understanding what's going on, Suzuka is usually there to calm her down. Alisa is proficient with English and loves dogs, owning about ten at her large mansion. Similarly to Nanoha's and Yuuno's first encounter, Alisa found an injuried Arf and took her to be treated in her house under the assumption that the familiar was just a big dog. Nanoha and Yuuno eventually met with Arf at Alisa's home.
