- "First, second, and third Floor Guardian, Shalltear Bloodfallen, at your command."
- -Shalltear's Introduction
Shalltear is a vampire of short stature and has the appearance of a buxom fourteen year old girl. Described as a true beauty, she has pale shiny skin, seductive red eyes, and fine facial features. Her silver hair is tied in a ponytail, allowing others full view of her face.
While so, Shalltear wears a soft black evening dress with a big heavy skirt. Her upper body is dressed in a lace embellished ribbon and a short tailored jacket. Her hands are donned with long lace gloves, not showing any bit of skin. However, her breasts are fake and are completely flat, similar to a boy's. She covers this up by using an excessive amount of breast pads.
When faced in battle fully-equipped, Shalltear can be seen dressed in a suit of red-colored full plate armor which looked like it had been drenched in blood. It wore a swan-shaped helmet which left only her pale face exposed. There are also plumes of avian feathers attached from either side of the helmet she wears. Additionally, the chest and shoulders of her armor had been styled into the shape of wings. As well as the crimson skirt-like armor covering her lower body.
In her True Vampire form, her appearance changes dramatically. Her mouth becomes a gaping circular maw not unlike a lamprey's, with a very long tongue hanging out. Her eyes' shape becomes quite inhuman and they glow brightly. Her form becomes hunched over and somewhat simian, with deadly claws on both her feet and hands. An eerie aura also surrounds her body. In this form, she wears a much simpler raggedy dress.
Shalltear has a very flirtatious personality and is very open with her sexual preferences, often to other characters' discomfort. Despite her apparent shamelessness and honesty, she can be quite innocent about certain things. On the other hand, Shalltear happens to also be perplex about her small figure physically, which she attempts to cover up by using breast pads.
As a true vampire, Shalltear is extremely proud and takes her position as a Floor Guardian very seriously. Yet at the same time, she has no patience or tolerance for failure and would often burst into fits of rage at signs of an unfavorable situation occurring. Shalltear will not hesitate to kill any servant who disappoints her; however, she will not punish others for failing in tasks that are impossible to begin with. When Shalltear fails her mission, she easily tends to fall into a state of depression sorrowfully and become very reflective of the sin committed by her. In fact, she believes that her crime must not go unpunished, feeling guilty of the horrible things she has done to cause Ainz trouble.
Shalltear is completely loyal to Ainz and in a romantic sense, is also considered to be the love rival to Albedo for his affections. She takes great joy in being able to prove her worth and fantasizes about the praise she expects to receive from Ainz. When a situation doesn't go in her favor, Shalltear fearfully panics about the scolding she believes that she will get by him. However, she seems to have a taste for enjoying the punishment Ainz ordered her to do like being his chair to sit on. After learning of the mistakes from her last mission, she began to act more vigilant and careful of the environment around her while understanding it accordingly.
Shalltear Bloodfallen was created by Peroroncino and use Shalltear as one of the subjects of his desires for his perversion and love of H-games.

While Ainz was masquerading as an adventurer, Shalltear is given the task of accompanying Sebas and Solution, and enslaving any criminals, who knew Martial Arts or magic. She converses with Sebas on their journey, recalling the times when their creators made their rounds on her floors, and expressing great interest in the mystery of the eighth floor. When the conversation turns toward her mission, Sebas's remark that Demiurge or Aura would have been a better candidate immediately causes Shalltear to enter a fit of rage. She threatens him with the prospect of a death battle, but slowly cools down when he apologizes. She holds reservations about the possibility of losing control from her Blood Frenzy, but still resolves to complete her mission without fail.
At this point, the carriage suddenly stops and they were surrounded by a group of bandits. However, the men prove to be no challenge whatsoever, as Shalltear and her Vampire Brides waste no time in slaughtering them. She makes their leader into a lesser vampire and splits off from the group of two now being Sebas and Solution. While entering the nearby forest where potentially more people could be, she and her vampire brides eventually come across a hideout and proceeds to engage in a frontal assault.
Trying to fill up her Blood Pool without much success, Shalltear soon comes across Brain Unglaus, who confidently meets with them alone. Feeling playful, she decides to toy with the mercenary, allowing him to attack without fear of retaliation. Brain breaks down after seeing all of his attacks be effortlessly deflected and runs away while Shalltear leisurely gives chase, following him to the mercenary's main hideout. Seeing the huge number of prey in front of her, she begins to lose control of herself as Blood Frenzy begins activating. She transforms into her true form and annihilates the entire base, leaving no one alive.
After annihilating them, Shalltear realized that Brain has escape through a tunnel exit. Her vampire brides inform Shalltear that there are unknown group approaching here. Shalltear confronted the group and slaughters them, but spared only one alive. Shalltear was slightly damage by the potion that she thrown at her and asked her name, and question her about the potion. After being questioned about the team she was part of, Shalltear summoned the vampire wolf to hunt down any human in the forest. However, one her familiars was killed and she quickly moves to the location where it was supposedly slain at. Shalltear arrives and encounters a new group that she quickly notices are much stronger than the previous one. She decided to capture them, but realizing her mistake, she was soon hit by a powerful spell that thwarted her attack for just a moment. Unable to stop it, she retaliate back with a powerful attack of her own that hit two of its member before everything goes dark.
Upon confronting her and attempting to use Wish Upon A Star to free her from the state of mind-control, Ainz realizes that Shalltear was actually under a World Item's influence as his super-tier spell wasn't enough to stop it. As a result, Ainz retreated temporarily in order to make preparations for his fight against Shalltear. With enough preparations like buffing himself up beforehand, Ainz began his attack first through a super-tier spell which is Fallen Down. Throughout the death battle between the two, she realizes that Ainz has no more mana points left, but is irritated at his calm behavior when he's in the verge of dying by her hands. However, she was counterattack by Ainz with his guild member's equipment including her creator's weapon. At last, she was finally killed by Ainz's super-tier spell, Fallen Down. Shalltear was later revived by Ainz and she was no longer under the mind control of their enemy's World Item. After her revival, she doesn't remember what happen and continued her duties to Nazarick.

- (To Albedo): "Don’t think that since you are the one in charge of the Guardians that you can stay beside Momonga-sama and think you have won. If you really think that way then everyone would laugh their teeth off."
- (To Ainz): "A beautiful crystal. You are the world’s most beautiful being. Even precious gems can not be compared to your pale white body."
- (To Brain): "Are you one of those? The type that doesn’t understand how high the sky is? Do you think you can touch the stars simply by reaching for them? That type of naivety should be reserved for children like Aura. It’s just disgusting with an adult."
- (To Brain): "Effort? What a meaningless word. I was created strong so such effort was unnecessary."
- (Dying in combat against Ainz): "Ahhhh, Long live Ainz Ooal Gown–sama. You are supreme, truly the strongest existence in all of Nazarick."
