Supreme Beings Edit
After the transition to the New World, Shalltear declared herself loyal to Ainz and considers him a love interest. She believes that Ainz is the most beautiful existence, mainly because of her necrophilia fetish. Her dream is to become Ainz's most important servant and his head wife.
As her creator, Peroroncino commands the most respect and loyalty from Shalltear than all the other guild members. If he had wished it, Shalltear would even make all of Nazarick her enemy.
Shalltear knows about Bukubukuchagama's job as a voice actress without any literal knowledge from the real world. Thus, she happens to confuse Bukubukuchagama's job with one that bestows a soul to a work though the use of her voice. In other words, a job that creates life is what she described it. Curiously, Shalltear wonders if Bukubukuchagama made Aura's setting to be at odds with her. Like all the other NPCs, Shalltear worships and respect Bukubukuchagama as one of the Forty-One Supreme Beings.
Floor Guardians Edit
Albedo is Shalltear's superior under Nazarick's hierarchical system. As a rival for Ainz's affections, Shalltear does not get along with her. In addition to that, they are also actively recruiting allies among the maids. However, she is willing to work together with Shalltear at times. As seen in Drama CD 2 where they work together to push for items such as a "Sleep with Ainz" coupon and many more.
Demiurge is one of Shalltear's colleagues. They both share similar interests.
Cocytus is one of Shalltear's colleagues. She and Cocytus share the same feeling of redeeming themselves in front of Ainz after their failure.
Aura is one of Shalltear's colleagues and her best friend. The two have a kind of sibling relationship between them, similar to the one between Peroroncino and Bukubukuchagama. It was even stated by Shalltear that her creator, Peroroncino, designed her to feud with Aura.
Mare is one of Shalltear's colleagues. Because he is Aura's brother, Shalltear uses him as a way of taking jabs at Aura.
Victim is one of Shalltear's colleagues. She had not met Victim before being teleported to the New World.
Area Guardians Edit
Shalltear is Kyouhukou's superior and thus, he is her subordinate. However, due to Kyouhukou's race and appearance, Shalltear avoids him and his residence at best she could.
They worked together for a short time where Sebas alongside Solution have been ordered to disguise themselves as wealthy and influential humans to gather information in the Kingdom while Shalltear would capture humans who know how to use martial arts. Sebas thought that someone like Demiurge would be better suited for the task, something that made Shalltear very angry. While Sebas doesn't like the way Demiurge treat humans, he's fine with Shalltear's evil personality.
Shalltear is infatuated with Yuri. During the auction, she recommended Yuri to be a third party to host the auction. She was excited, claiming that she is the most suitable for the task. According to Albedo, Shalltear's infatuation with Yuri is due to her fetishes.
Shalltear and Solution are on good terms. Solution supports Shalltear's love for Ainz and they share several interests.
Shalltear doesn't like the idea of being near Entoma, because she eats the cockroaches in Kyouhukou’s room.
They both share a feeling of infatuation for Ainz. Neuronist views Shalltear as a rival for Ainz's affections and calls her a “brat.”
Initially Sous-chef had no prior association to Shalltear after the Bloody Valkyrie incident. After Shalltear was freed from her mind control, she was filled with self-pity and embarrassment that she interned herself in the Sou-chef's bar, much to his displeasure. He found her to be lacking gracefulness and character as compared to his other male patrons. However, since she is a Floor Guardian, he kept a face of politeness, though subtly being rude to her and providing cheaply made drinks.
He sympathized with Shalltear for her involuntary uprising, as he considered betrayal his function. Eclair also attempted to recruit her into joining him in his conquest of the Great Tomb of Nazarick, only to cause her to sink more into her depression.
