Yuri Alpha is the vice-captain of the "Pleiades Six Stars," the battle maid squad of the Great Tomb of Nazarick. She was created by Yamaiko, one of the three female members of Ainz Ooal Gown. Yuri Alpha is a beauty with an intelligent look, wearing glasses and a blue-collar around her neck, most likely to keep her head attached to her body since she is a Dullahan. She wears her hair tied into a low-cropped bun at the back of her head. Lacking a metal plate in front of her skirt, her dress emphasizes mobility rather than defense. She is equipped with spiked gauntlets. As shown in her Karma value, Yuri is good-hearted and one of the two "safe" Pleiades to humans. Thus, she is relieved when Ainz tells her not to kill humans without proper reasons. When given permission to do as she pleases, Yuri chooses to help people in destitution. She uses "boku" as a first-person pronoun when speaking in private, revealing a somewhat childish nature. Her behavior is strict and like that of a teacher. She is a workaholic, unable to relax with the thought of free time. Due to her personality, she often works as a chairperson. While this does not extend to taking the jobs of others, she gladly accepts any request to do so. Interestingly, her status as an undead makes her very cold and calculating. However, her alignment and mental imprint of her creator allows her to enjoy short bouts of emotional outbursts, but these emotions are quickly repressed, similar to Ainz's emotions.
