Yuri Alpha/Relationships

Ainz Ooal Gown
Yuri Alpha is loyal to Ainz and as one of the good denizen of Nazarick, she felt relieved when Ainz said not to kill humans without proper reasons. In a way, Yuri thinks of Ainz being the nicest person after her creator. After confronting Ainz again with the matter concerning Solution and it being resolved peacefully, she made a mental note about Ainz, the master before her is as kind as her creator, Yamaiko.

Yamaiko
Yamaiko is Yuri's creator and her personality might have influenced Yuri.

Albedo
Albedo is interested in recruiting Yuri Alpha to her side in the campaign for the position to be Ainz's queen.

Shalltear Bloodfallen
Yuri Alpha is not good in dealing with Shalltear because of her undead fetish, as Yuri is of an undead race.

Aura Bella Fiora
During the auction, Yuri said that if she was allowed to be biased, she would definitely cheer for Aura. When Aura compared her to a teacher she took it as a compliment.

Yuri is close enough to Aura to the point they refer to each other with nicknames outside of work. That is because the Supreme Beings who had made them were close to each other, and they felt similarly close to each other.

Mare Bello Fiore
Yuri is close enough to Mare to the point they refer to each other with nicknames outside of work. That is because the Supreme Beings who had made them were close to each other, and they felt similarly close to each other.

Pandora's Actor
When Yuri alongside Shizu accompanied Ainz and Albedo to the Treasury, she met Pandora's Actor for the first time, she was displeased upon being called young lady by him because of her pride as a battle maid of the Pleiades.

Sebas Tian
Sebas Tian is Yuri Alpha's superior, thus they have a professional relationship. Even after Sebas was reassigned to look after Tuare for her maid training, Yuri still offered advice for her colleague on how to train a human without wearing her down from overwork, as it would bring disapproval to Ainz Ooal Gown.

Lupusregina Beta
Yuri sees Lupusregina Beta as a terrible younger sister just as bad as Solution Epsilon. But despite that, Yuri still loves her as they are still sisters.

Narberal Gamma
Yuri has shown a low key jealous side for Narberal, as her younger sister is frequently with their master during their undercover missions as adventurers.

Solution Epsilon
Yuri sees Solution Epsilon as one of the bad younger sisters out of all her other sisters.

However despite Yuri's general distaste and disapproval of Solution's "hobbies", Yuri is still shown to harbor genuine love and attachment to her sister. As seen where Yuri showed great distress at the prospect of having to reprimand Solution during the time the time she stole Ainz's personal bathhouse slime,Miyoshi. And during Ainz's order for her to question her younger sister, Yuri's mind was thrown into inner turmoil when misunderstanding Ainz's request to question her as using physical interrogation to question her.

CZ2I28 Delta
Yuri sees Shizu as the only good girl in the Pleiades and one of the obedient children out of all her other sisters. Yuri was supportive of Shizu making friends with Neia during the assignment in Roble Holy Kingdom.

Entoma Vasilissa Zeta
Yuri thinks Entoma isn't a bad girl and one of the obedient children out of all her other sisters.

Aureole Omega
Aureole Omega is the leader of the Pleiades Seven Sisters, thus Yuri Alpha's superior.

Out of all seven of the Pleiades sisters, Aureole was created to be seen as the youngest and as such Yuri sees and treats her as her youngest sister despite her being her direct superior. There relationship seems to be close enough that Aureole is more than willing to allow lend her high level minions to Yuri if needed be.

Yuri in turn sees Aureole as her adorable youngest baby sister and has even given her own nickname for her as "Au-Chan".

Increment
Increment was created by Yamaiko, the same Supreme Being who created Yuri, which in a way also makes her something akin to a sister to Yuri Alpha. Yuri herself has displayed a level of familial love and familiarity with her, as seen when seeing her pure and innocent eyes as well as her movements usually bring a smile to Yuri's face and the way Increment tenses up her back while she is reading makes Yuri feel very warm.

Decrement
Decrement was created by Yamaiko, the same Supreme Being who created Yuri. Decrement is more reserved than her "sister" NPCs, usually deferring to her reading and alone time. As Yamaiko was a teacher in the real world of 2138, her solitude and reading might be a trait that she inherited from Yamaiko.

Due to Decrement also being created by Yamaiko, its highly likely that similarly to Increment, Yuri also feels a level of familial love and care for her.

Pestonya Shortcake Wanko
Yuri is close enough to Pestonya to the point they refer to each other with nicknames outside of work. That is because the Supreme Beings who had made them were close to each other, and they felt similarly close to each other.

When Pestonya went against Ainz's order and was imprisoned in the 5th Floor, Yuri was not worried because she had Nigredo to keep her company. If they had been imprisoned in the 7th Floor, she might have been worried for Pestonya. But when Ainz hinted to her that she can choose any member of Nazarick to assist her in building a sponsored orphanage, she happily chose both of them and freed them from confinement.

Eclair Ecleir Eicler
Yuri is close enough to Eclair to the point they refer to each other with nicknames outside of work. That is because the Supreme Beings who had made them were close to each other, and they felt similarly close to each other.

Tuareninya Veyron
Yuri serves as Tuare's maid instructor to prepare her for her eventual role as the Head Maid in E-Rantel, a territory which the Sorcerer Kingdom has annex so far. Although she keeps their relationship professional, Yuri cannot help but felt pity towards the human, as she and Pestonya are the only ones who treats her respectively. While carrying the burden as part of her duty, this was due to Tuare's difficulties fitting in the Great Tomb of Nazarick with other Homunculus Maids around her.
