As the absolute ruler of the Great Tomb of Nazarick, Ainz has Aura's complete respect, admiration, and loyalty that she has pledged to serve him without hesitation. Originally, Aura believed that Ainz was a much scarier person, but was quite shocked when she and her brother witnessed his compassionate side that he showed to his subordinates. Aura thinks of Ainz as being the nicest person after her creator, Bukubukuchagama, although she agrees when CZ2128 Delta comments that Ainz is the nicest for staying with them until the end.
Being the creation of Bukubukuchagama, Aura has the utmost respect, loyalty, and love for her to the point that even the sound of her bubbly voice emitted from the wristwatch fills Aura with immense happiness and joy. She holds this wristwatch in high regard because it is like a gift bestowed by her master. In fact, she cares for the wristwatch much more than her own pets, thinking that the wristwatch is a greater reward than the ring of Ainz Ooal Gown. This shows how significant the strapped piece of iron recorded with her creator's voice is to her and the sentimental value it has that she treasures.
Aura is the domineering one of the twins, with Mare obeying her every word. Despite her bossy nature, she genuinely cares about Mare, always making sure he remembers to take care of himself if they separate.
In the Emissary of the King, Aura says that besides Mare and her beasts, Albedo is the one she is closest to. They spend some time together alongside Shalltear and even share a bath together. When she hears that Albedo doesn't have many clothes, she offers some of her and Mare's clothes.
At first glance, Aura doesn't appear to get along with Shalltear and often gets into small quarrels with her, but in reality, the two of them are quite close as if they are true sisters. After Shalltear is resurrected and learns about her betrayal towards Ainz, Aura attempts to cheer the vampire up. When Shalltear begins harboring thoughts of not being worthy of Ainz's love because of that, Aura then decides to make a declaration to the vampire, saying she is going to take part in the romance. In other words, Aura states she will be the one who is going to aim at earning Ainz's love for herself if Shalltear casts aside her dream. With those words said, Aura immediately makes a quick dash out of the bar in the 9th Floor of Nazarick while her face is shown blushing with embarrassment.
Demiurge is Aura's colleague. Demiurge trusts Aura when it comes to someone to watch over Albedo and Shalltear.
Cocytus is Aura's colleague. She teases him for being a "nudist" since he has no need for clothing and thus he never wears any.
Victim is one of Aura's colleagues. She had not met Victim before being teleported to the New World.
During the auction, Aura is annoyed by how Yuri acts like a teacher. Yuri takes it as a compliment and even says that if she is allowed to be biased, she will definitely cheer for Aura.
Aura is close enough to Yuri to the point that they refer to each other with nicknames outside of work. That is because the Supreme Beings who created them were close to each other, and they felt similarly close to each other.
During the auction, Aura suggests that Lupusregina, alongside Solution and Narberal, investigate some clothes for the female guardians.

Aura and Neuronist Painkill do not seem to interact much. However, despite being fellow denizens of Nazarick, Aura seems somewhat disgusted by Neuronist, as when the latter leans in closer while talking, Aura's response is to run away in the opposite direction.
Being a new species of the New World, Aura shows an interest in Hamsuke. However, seeing that Ainz wants to boost his fame by subjugating Hamsuke, she relents and instead asks for the chance to skin her if Ainz decides to kill her.
With her collecter's spirit, Aura wants to have Rororo for her own, but is rejected by Cocytus, saying that the Lizardmen are under his care and will not permit her stealing it. She instead asks for its children and Cocytus gives a tentative answer as he is not sure if the lizardmen want to use its children as mounts.
During the invasion of the tomb by workers, one of the groups, Tenmu, was composed of Erya and three elven slaves who Erya had treated horribly. After his death, Ainz allowed them to stay, believing that they weren't there by choice and, as a result, should not be considered trespassers. Ainz assigns them to the dark elf twins so that they can interact with other elves and help with their maturity. The former elven slaves have become absolutely loyal to Aura and Mare and will even help them get dressed. While Aura is annoyed by this, Ainz is very pleased that the elves are taking a nurturing role to the twins. He forbids Aura from killing the former slaves, even if they are annoying, and that if they are too much hassle, he will simply assign them elsewhere.
