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.

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.

The Bloody Valkyrie Arc
Yuri Alpha greets Ainz upon his return to Nazarick in the Treasury with Albedo and CZ2128 Delta. Together they make their way through the Treasury's defenses with ease due to their undead and artificial statuses. Entering the inner Treasury the groups encounter Tabula Smaragdina. 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. The situation was defuse when Ainz ordered Pandora's Actor to reveal himself. After Ainz had retrieved the World Items and bequeathing Pandora's Actor with a Ring of Ainz Ooal Gown, she later assists Pandora's Actor in moving treasure to the Throne Room.

The Men in the Kingdom Arc
She along with the majority of the battle maids all participated in Demiurge's plan during his invasion of the Re-Estize Kingdom, acting as the subordinate of Jaldabaoth while wearing a mask to conceal her actual face. She as well as CZ was pitied to fight against Evileye, while Entoma, Lupusregina and Solution fought against Nabe and Jaldabaoth against Momon. The former battle being real while the later two were just a pretense, After awhile when Jaldabaoth called for a retreat, she and the other maids recalled and teleported out of there with Jaldabaoth.
