Yuri Alpha

Yuri Alpha (ユリ・アルファ, Yuri・α) 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.

Appearance
Yuri Alpha is a beauty with an intelligent look, wearing glasses and a choker. 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.

Personality
As shown in her Karma value, Yuri is good-hearted and one of the two "safe" Pleiades to humans. Thus, she felt relief when Ainz said not to kill humans without proper reason. When given permission to do as she pleases, she chooses to help people in destitution. She uses "boku (ボク)" as a first person pronoun when speaking in private, revealing a somewhat childish nature.

Her behavior is strict like a teacher's. Due to her personality, she often works as a chairperson.

Sensing something amiss, Albedo realized it was not so, and ordered for the impostor's destruction. Both CZ2128 and Yuri were hesitant to attack the form of the Supreme Beings.

 * (To Lupusregina Beta): "You’re terrible. You’re as bad as Solution. Why are my little sisters like this? Really, the only good one is Shizu… although I suppose Entoma isn't a bad girl."
