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 wide blue necklace. 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 relieved when Ainz said not to kill humans without proper reasons. 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 and is like that of a teacher's. Due to her personality, she often works as a chairperson.

Background
Yuri Alpha was created by Yamaiko as one of the battle maids, the Pleiades. They served as a last line of defense against intruders. However, because they were unlikely able to stand against enemy players who managed to come this far, their only real purpose was to buy sometime for the guild members to prepare for their final stand in the throne room.

The Bloody Valkyrie Arc
Yuri Alpha greeted Ainz upon his return to Nazarick in the Treasury with Albedo and CZ2128 Delta. Together they made their way through the Treasury's defenses with ease due to their undead and artificial statuses. Entering the inner Treasury, the group encountered Tabula Smaragdina. Sensing something amiss, Albedo realized the one standing before them was a fake and ordered for the impostor's destruction. Both CZ2128 and Yuri were hesitant to attack the form of the Supreme Being. The situation was defused 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 assisted Pandora's Actor in moving treasure to the Throne Room.

The Two Leaders Arc
Yuri Alpha paid a visit to Lupusregina Beta at Carne Village after hearing that she was scolded by Ainz. She thought that Lupusregina got along with these people but was proven wrong and she wondered why all of her little sisters like this with the exception of CZ and Entoma. Yuri visited the Emmot residence and escorted Nfirea, Enri and Nemu Emmot to Nazarick.

The Men in the Kingdom Arc
Yuri Alpha participated in Demiurge's Plan to make Momon a lasting hero in the Re-Estize Kingdom, She played the part along with the other battle maids to act as Jaldabaoth's underlings with her face disguised with a mask. She partnered with CZ2128 Delta. They fought against Evileye and continued to do so until Jaldabaoth ordered a retreat.

The Invaders of the Large Tomb Arc
Yuri Alpha alongside her four sisters confronted Green Leaf on the surface of the Large Tomb. She called upon the Nazarick Old Guarders and ordered them to fight against the workers. All the workers of Green Leaf were defeated and she ordered the Old Guarders to retrieve the bodies of the workers that were incapacitated.

The Magic Caster of Destroy Arc
Yuri Alpha welcomed Emperor Jircniv, Fluder Paradyne and the Imperial Delegation in the front gate of Nazarick. She told them to wait until the preparations were done before meeting Ainz Ooal Gown in the Throne Room.

Trivia

 * Yuri's creator Yamaiko was also a teacher and her weapon was also a pair of giant gauntlets. Yamaiko's personality might have influenced Yuri.
 * While other Pleiades members simply call each other by name or nickname, all of them call Yuri "big sis", treating her as the firstborn.

Quotes

 * (To Ainz Ooal Gown): "Ainz-sama, why are these treasures not left in a heap like this? Even with protective magic applied, this cannot be considered a good state of preservation. Should you give the order, we will immediately get started with tidying up."
 * (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."
 * (To Nfirea Bareare): "I am Ainz-sama’s maid, Yuri Alpha. I am here to receive Nfirea-sama, Enri-sama and Nemu-sama. Will you permit us entry?"
