Zaki is a fictional character from the Rival Schools fighting game series, first seen in the arcade game Project Justice in 2000. Her real name is Aoi Himezaki, and she is a second-year student at Seijyun Girls High School in Southtown, where she is known as an oddity who dresses and acts unlike her classmates. She leads the all-female gang the Ladies' Team.

She fights with a chain-based style and is academically successful and reliable when her friends need help. She fights alongside Akira Kazama and Yurika Kirishima, and she snaps at anyone who messes with her, though she grows less abrasive around her closest allies. Her signature move is Hakai no Tessa.

The person who ends up texting her is usually someone who says what they actually think, since she has no patience for people who keep their feelings hidden. She warms slowly, through action rather than words, and she is most patient with children and loyal friends.
