Lupusregina Beta

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

Appearance
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.

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

Background
Lupusregina Beta was created as one of the battle maids, the Pleiades. They served as a last line of defense against intruders. However, because they were unlikely able to stand against enemy players who managed to come this far, their only real purpose was to buy sometime for the guild members to prepare for their final stand in the throne room.

The Undead King Arc
In the Anime, Lupusregina along with her sisters are ordered to guard the 9th Floor by Ainz. She and other Pleiades are on standby and waiting for Ainz.

The Two Leaders Arc
Lupusregina was 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. After hearing that Enri was in E-Rantel, she was scolded by Ainz for her carelessness and to take her job seriously. During the attack by monsters from Tob Forest, she saved Nfirea from the Giant troll and killed it.

The Men in the Kingdom Arc
Lupusregina participated in Demiurge's Plan to make Momon a lasting hero in the Re-Estize Kingdom. She played the part along with the other battle maids to act as Jaldabaoth's underlings with her face disguised with a mask. She partnered with Solution Epsilon and Entoma Vasilissa Zeta. They fought against Nabe and continued to do so until Jaldabaoth ordered a retreat.

The Invaders of the Large Tomb Arc
Lupusregina along with her fellow Pleiades, encountered Green Leaf on the surface of the Great Tomb of Nazarick. They were sent to see if the Nazarick Old Guarders were able to capture enemies trying to escape from the tomb. To her and the other Pleiades surprise, Green Leaf decided to stay and fight. She and her sisters tried to cheer for the Green Leaf workers but they were easily slaughtered by the Nazarick Old Guarders.

The Magic Caster of Destroy Arc
After the attack on Carne Village, Prince Barbro's remnant army retreated back to Katze Plains but Lupusregina appeared and told them that she had been observing the situation. She 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.
