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, Yuri 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. She is workaholic, unable to relax with the thought of free time. Due to her personality, she often works as a chairperson. While that did not extend to taking the jobs of others, she would gladly accept 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.

Background
Yuri Alpha was created by Yamaiko as one of the battle maids, the Pleiades. They served as the last line of defense against intruders. However, because she is unlikely able to stand against enemy players who managed to come this far, her only real purpose was to distract the invaders until the guild members of Ainz Ooal Gown are able to fully prepare for their final stand in the throne room.

Yuri Alpha along with her sisters are ordered to guard the 9th Floor by Momonga. She and other Pleiades are on standby and waiting for him.

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 the treasure to the Throne Room.

The Dark Hero's Story Arc
Yuri Alpha was selected by the Floor Guardians to act as a host to the auction. During the auction she said that if she is allowed to be biased, she would definitely cheer for Aura. When she read the first collected requests from the guardians, she informed Demiurge that there was a problem because there were four inappropriate items mixed in the box and asked if they were allowed for the action. After the problem was resolved she started the auction again.

Later, she reported to Ainz about the auction and the Floor Guardian’s requested items. She informed that Entoma wished to have some human tender meat if possible but Ainz refused this request saying he won’t kidnap innocent people. When Ainz read the other requests he was left speechless because of their content. When he tried to ask Yuri for an explanation she was unable to give him a proper answer.

The Maid Tea Party Arc
Yuri Alpha participated in the monthly Pleiades report and tea party along with her sisters. She asked Entoma to prepare the tea and snacks. She acted as the Deputy Leader and opened the session. When her sisters started getting jealous of Narberal because of her closeness to Ainz, she interrupted them. She then reported her activities. She informed her sisters that she and CZ2128 held the 1st Great Tomb of Nazarick Love Love Ainz-sama Guardians' Special Grand Auction. When Entoma accidentally spilled blood in CZ2128’s drink and was ordered by her to drink it as a punishment, Yuri supported her saying that it is bad to waste food.

The Pleiades Day Arc
Yuri Alpha had begun training Tsuare as a maid for the girl's eventually position as Head Maid in E-Rantel. After she finished her session with the human, she found herself with free time and was unable to think of anything to do. Thus she returned to her quarters on the 9th Floor. Yuri met with her two sisters, Lupusregina and Narberal idly doing nothing which frustrated her. Just as she was scolding them for their lax behavior she was summoned by Ainz Ooal Gown to address an altercation that occurred between him and Solution.

Once Yuri forced Solution to answer Ainz and discovering her discontent, Ainz charged Yuri in assessing whether the other Battle Maids had any grievances they wished to addressed. She met with Shizu and later Entoma, learning their requests. Upon returning with her report, Ainz approved her suggestion of building a new orphanage and promised to put all of the Sorcerer Kingdom's resources behind her. She was allowed to request any help, which permitted her to free Pestonya and Nigredo from confinement.

The Craftsman of Dwarf Arc
After Ainz Ooal Gown slayed Olasird'arc Haylilyal, he opened a Gate and transported the Dragon Lord's corpse to Nazarick, ordering Yuri to preserve it on the 5th Floor.

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.

Quotes

 * (To Ainz): "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): "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): "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?"
