Lupusregina Beta (ルプスレギナ・ベータ, Lupusregina・β) is a werewolf battle maid and member of the "Pleiades Six Stars", the battle maid squad of the Great Tomb of Nazarick.


Lupusregina Beta is a brown-skinned beauty with an athletic look and red hair tied in two long braids. She wears a maid uniform with short sleeves and long black gloves with a skirt that has a long slit on its left side, revealing thigh high white stockings. She is equipped with an imposing black and silver scepter slung across her back.


Lupusregina Beta has a very bright and outgoing personality, but is also able to conduct herself like a perfect lady. She is sociable and friendly towards humans though it is only a mask to conceal her brutal and cunning personality. She also likes to make lewd jokes and has a tendency to suddenly appear behind people and disappear without notice.


Lupusregina Beta was created as one of the battle maids, the Pleiades. They served as a 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.

The Two Leaders Arc

Lupusregina is given a mission to spy in Carne Village and to protect three people in the village: Enri Emmot, Nfirea Bareare and Lizzie Bareare. She visited the village with stone golems to help with the construction of the new wall. She is also the one responsible for delivering the alchemical items and apparatuses to the Bareares. She followed Enri, Nfirea and the goblins when they were exploring the Great Forest of Tob searching for both herbs and information about the forest. She received a newly developed potion made by the Bareares, and then reported it for Ainz. When Enri decided to make some drinks, she asked Lupusregina if she knows how to make delicious drinks. In response, Lupusregina claimed that she knows how to do, but she serves only the Supreme Beings as a maid and thus she does not help other people in chores and prefers instead to laze around.

When the inhabitants of Carne Village decided to protect their village from the possible attacks of the army led by the Giant of the East and the Demon Snake of the West, Lupusregina suggested asking Ainz for help as he would easily solve the problem, but her suggestion was declined, as Enri said that they should do as much as they can by themselves. Lupusregina had a disappointed look in her face after hearing Enri answer, but said that they should work hard. After hearing that Enri was in E-Rantel, she was scolded by Ainz for her carelessness and was told to take her job seriously.

Afterwards, Lupusregina talked with Enri about the matter of her being appointed to be the new chief of the village. Lupusregina gave some advice to her saying that it doesn't matter if she is the chief or someone else is the chief, because she would mess up sooner or later. She said that there are only forty-one people that would never make a mistake and that there is no point worrying about what happens when Enri fail and that nobody is better suited for the job than her. Lupusregina also said to Enri that if the goblins couldn't save the village, they would prioritize her safety first. However, if she was the chief of the village then this scenario would change as the village would become her property and they would fight to protect the village to the bitter end.

While so, Lupusregina saw the villagers gathering in the village square, because Enri was appointed as the new chief. Yuri Alpha appeared behind her and asked about Carne Village, saying that was the reason she got scolded by Ainz. Lupusregina said that a new leader has just arisen and wondered what kind of faces the villagers would make if they were attacked and everything was set ablaze, much to Yuri‘s displeasure. During the attack by monsters from Tob Forest, she saved Nfirea from the Giant troll and killed it.

Later, Lupusregina and Yuri escorted Enri, Nfirea and Nemu Emmot to Nazarick through teleportation as Ainz wanted to give them a reward for the newly developed potion made by the Bareares.

After the attack on Carne Village, Prince Barbro's remnant army retreated back to Katze Plains until Lupusregina appeared in front of them and told the group that she had been observing the situation for a while now. Lupusregina summoned thirty level 43 red hat goblins, killing everyone and she personally tortured Prince Barbro for half an hour before he died from the torment.
