Lupusregina Beta

Lupusregina Beta (ルプスレギナ・ベータ, Lupusregina・β) is a werewolf battle maid and a member of the "Pleiades Six Stars," the battle maid squad of the Great Tomb of Nazarick. She was created by Beast King Mekongawa.
== 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.
The Light Novel shows Lupusregina wearing a garter belt with her stockings, while the Anime omitted it.
== Personality ==
Lupusregina Beta has a very bright and outgoing personality but is able to act accordingly like a perfect lady. She is sociable and friendly towards humans. However, this is only a mask to conceal her brutal and cunning personality. She also enjoys making lewd jokes to people like Enri.
Lupusregina tends to use her 'Complete Invisibility' spell frequently in order to appear behind someone's back without being detected, as she loves to startle people. Yuri has claimed that Lupusregina can be as sadistic and evil as her sister Solution. The author Maruyama has stated on Twitter that during a full-moon at nighttime, she becomes a little bit crueler.
Lupusregina is considered the friendliest of the battle maids by the Homunculus Maids. They also think that being approached by her is a sign of good fortune.
In the Web Novel, she is not a sadist, just a cheerful character who loves to eat.
== Background ==
Lupusregina Beta was created by Beast King Mekongawa to be one of the battle maids, the Pleiades. They served as a last line of defense against intruders. However, because she is unlikely to be 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 were able to fully prepare for their final stand in the throne room.
== Chronology ==
=== The Undead King Arc ===
Lupusregina, along with her sisters, are ordered by Momonga to guard the entrance of the 9th Floor. She and the other Pleiades are on standby and waiting.Overlord Volume 01 Chapter 1: The End and the Beginning
=== 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 visits 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 follows Enri, Nfirea, and the goblins when they explore the Great Forest of Tob in order to search for both herbs and information about the forest. She receives a newly developed potion made by the Bareares, and Nfirea wants her to report the news about it to Ainz. When Enri decides to make some drinks, she asks Lupusregina if she knows how to make delicious drinks. In response, Lupusregina claims that she knows how to, but she serves only the Supreme Beings as a maid and thus she does not help other people with chores and prefers instead to laze around.
Although the inhabitants of Carne Village decide 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 suggests asking Ainz for help since he will easily solve the problem. However, Enri rejects her idea of asking help from Ainz a second time, stating that they should do as much as they can by themselves without depending on their savior too much. After hearing her answer, Lupusregina has a disappointed look on her face but says that they should work hard to keep the village safe. Once Ainz hears the news of Enri being present in E-Rantel, he scolds Lupusregina in his office for her carelessness and tells her to take her job seriously.
Afterward, Lupusregina talks with Enri about the matter of her being appointed to be the new chief of the village. Lupusregina gives her some advice, saying that it doesn't matter if Enri is the chief or someone else is the chief because she will mess up sooner or later. She says that there are only forty-one people who will never make a mistake and that there is no point worrying about what happens when Enri fails and that nobody is better suited for the job than her. Lupusregina also tells Enri that if the goblins can't save the village, they will prioritize her safety first. However, if she is the chief of the village, then this scenario will change as the village will become her property and they will fight to protect the village to the bitter end.
Shortly after, Lupusregina sees the villagers gathering in the village square because Enri has been appointed as the new chief. Yuri Alpha appears behind her and asks about Carne Village, saying that was the reason she got scolded by Ainz. Lupusregina says that a new leader has just arisen and wonders what kind of faces the villagers will make if they are attacked and everything is set ablaze, much to Yuri‘s displeasure. During the attack by monsters from Tob Forest, she saves Nfirea from the Giant troll and kills it.
Later, Lupusregina and Yuri escort Enri, Nfirea, and Nemu Emmot to Nazarick through teleportation as Ainz wants to give them a reward for the newly developed potion made by the Bareares.Overlord Volume 08 Side Story 1: Enri's upheaval and hectic daysOverlord Volume 08 Side Story 2: A day of Nazarick

Some days later, Regi drinking in the Sing Apple Pavilion, overheard from a few workers had heard about the Greetings and Victory Festival. Since it was known that Regi had participated in the event, the workers asked her what it was about, which she disclosed of being a masquerade festival with activities of handing out the harvest and fighting exhibition. Later she was retrieved by Peshurian for a team meeting back at their hideout.
Due to Regi's early drinking habit, Zero was concerned about this as she picked up ever since Shizuni, though Regi claimed that she was sober enough. On the topic of the meeting, it was revealed that the emperor hired New Six Arms to act as security for the Greetings and Victory Festival that will be hosted in the imperial capital. As this was unexpected, that a foreign nation would be hosting an event from the Sorcerer Kingdom, the Pleiades maid suspected this was part of some plan by Momonga. It was confirmed when she asked Zero if the Empire got permission from the heteromorphic.
Later she passed this information on the job to Momonga and his advisors. There was more to the job as the emperor wanted the workers to hunt down the dissident groups that might cause trouble during the festival. It was deduced to be one of the groups belonging to the Anti-Imperial Faction which the Sorcerer Kingdom had intercepted secret letters from. Momonga then ordered to assist the workers and the Empire to ensure that the festival proceeded as the benefits of it being hosted in a foreign country was desirable.
The maid then returned to Arwintar and went to the Singing Apple Pavilion for a meal of pork stew. There she bragged about an escort job her team got which involved transporting supplies from the Sorcerer Kingdom in E-Rantel to Arwintar for the festival. The news was overheard by a anti-imperial supporter who Regi was aware of and he informed his associates of the shipment. Regi and her team then ambushed the dissidents when they laid in wait for the alleged convoy.
After handing the criminals over to the authorities, the workers partook in a small celebration, though Zero was more wary as he felt that the job was too simple. Regi and the others soon came to agree, given that the instruction were to intentionally leak the information came from Jircniv. Their leader Zero suspected that the emperor was holding out on them and that there was still a bigger ploy that needed to be prevented.
Indeed there was, Regi with the assistance of Sebas and Naberal managed to gain information from a member of the anti-imperials. This information includes positions of the dissidents movements and most of all a plan to ambush the emperor while he was making his way to the Grand Arena. Regi passed this information to the workers, who in turned passed this to the imperial knights. At the time of the festival, Regi is a new costume patrolled the streets with Narberal to capture the dissidents. Thanks to Regi's and her team's involvement it allowed them to arrest the anti-imperials involved. After the arrest Regi expressed disappointment in missing out on the fighting exhibition, though was told by Zero that there was always next time.
After the festival Lupusregina reported to Momonga to share her findings that the Theocracy was working through its agents in the Temple to support the anti-imperial group composed of former slave merchant that was responsible for the failed attack on Jircniv. Her mission was deemed a fruitful one as Nazarick now had strengthen their bond with the Empire and also deepened their concern about the Theocracy's hidden actions. That being said, Albedo and Momonga provided some good news that the protagonist had returned from beyond the Crack and that her sisters were alive. A plan was currently in progress to retrieve them much to Lupusregina's delight who wanted to be allowed on the rescue team once preparations were complete.
Since CZ's return would occur in the future, the maid then returned to New Six Arms with a claim that Shizuni had been reported wandering the Tob Forest. The news excited her teammates who were worried about their missing member and relieved that Regi was back in full spirits. As the team celebrated for their eventual reunion with Shizuni, Lupusregina contemplated of how ever since she inserted herself as a worker in New Six Arms that she had become good friends with them, noting how considerate and caring they were during her sister's absence. That despite their appearances these men were good people, though noted to herself that if she ever got permission she would love to betray them and toy with them in the most entertaining way possible.Mass for the Dead Special Event: The Glorious Imperial Capital Harvest Festival 
It was only when the protagonist returned safely with news that the lost were trapped on "other side" of the Crack was hope reignited for the Pleiades. Lupusregina joined the team for the rescue operation, equipped with specially made gear that could allow her to traverse safely through the "chaos environment". Upon finding and awakening Yuri, Lupusregina embraced her sister. When Gazef Stronoff approached, Lupusregina and majority of the maids hid to avoid the Warrior Captain from recognizing them as the Demon Maids of Jaldabaoth. She and the others watched from the shadows as Darkness and the human interacted before the latter left to carry back the bodies of King Rampossa III and Brain through a Crack to return to the Kingdom. Whilst staying hidden, Lupusregina witnessed the sudden appearance of Enhela and overhead the unbelievable conversation between him and the protagonist.Mass for the Dead Chapter 16: Name of God
Just as Enhela Read Gahi attempted to kidnap the protagonist, Lupusregina and Narberal launched a flurry of magical attacks at him forcing him to retreat by summoning a Crack and vanish. The feat of the priest using teleportation magic confused the maids as such magic was impossible due to the magical interference of the Cracks. However Lupusregina confirmed that there was no [Perfect Unknowable] involved and that the priest truly teleported. 
Though the Pleiades were more focused on what Enhela said to the protagonist. According to CZ who overheard the conversation, the Theocracy priest referred the protagonist as "brother" and that they were both servants of Kuyō, which demanded an explanation.
However the answers she and her sisters received had the protagonist admitting that he was a creation of the Sea of Possibilities, not a real NPC created the Supreme Beings. Lupusregina believed that Enhela was spewing nonsense as the protagonist to her memory was created by Beast King Mekongawa and has always existed in Ashurbanipal. But when the protagonist asked her to recall when they first met, Lupusregina only found that there were gaps in her memory. It became evident that the protagonist was inserted into Nazarick, and the NPCs he encountered had their memories altered to accept him. Not sure how to respond to the protagonist, whether to treat him as a friend or enemy, Lupusregina and her sisters agreed to let Momonga decide his fate.
The Pleiades and Darkness then exited the Crack, appearing in the Tob Forests. There Lupusregina was relieved that everyone was just safe, chuckling as Entoma and CZ were bickering on who was older.Mass for the Dead Special Event: Two Shields That Will Never Fade

The Pleiades maid would resume her role as Regi in New Six Arms. During a slow period while eating a meal at an inn in Arwintar with her human companions, she and Shizuni witnessed a bard performing a ballad. The existences of bards and how they played in disseminating information intrigued the undercover agents. Lupusregina and CZ then brought the idea of the Bard Plan to Momonga and their superiors to create Sorcerer Kingdom bards to spread their nation's glory. It was approved by their master who had Narberal join as a third member of the project. After collecting the electric guitar and stand mic from Pandora's Actor, the trio hit the books in the library for any musical themes related to the items they collected. 
They came across the rock music genre, inspiring the maids to create a rock band. Lupusregina for her part served as the lyricist and manager of the newly minted Βγδth. Her band went around Nazarick performing for the general maids. While a big hit in their debut, the team began to have tension over small minor things such as the lyrics of the songs being too critical towards Momonga. 
A falling out was avoided thanks to the intervention of Shalltear who helped Βγδth vent out their frustrations in a culling of Chaos Beasts on the 10th Floor. Afterwards at the invitation of Shalltear, Lupusregina and her band were challenged by LittleMasStar in a finale show. For the occasion, Lupusregina lacking a rock theme attire opted to dress in her worker clothes. Her team lost to the idol group but the success of Βγδth was enough to convince Momonga to begin the next steps of the plan by introducing the items used in rock into the Empire. Lupusregina and CZ took a prototype of a New World electric guitar made by a Tsuibayaya to show it to their teammates in New Six Arms, though their reactions to the novelty were less than satisfactory.Mass for the Dead Special Event: Rock the Pleiades
Lupusregina on one of her days back in Nazarick, spied Shalltear in Casino Resort Nazarick followed by Momonga touring the facility. The maid called out to the Floor Guardian and nearly Momonga, but was stopped as the latter was invisible to the staff as he wanted to view things incognito. Lupusregina hearing how he wanted to know the opinions of the casino from the general maids offered to act as his intermediary and collect information. 
Later she shared what she heard to Albedo and Momonga, in that the general maids were not always aiming for a prize and merely worshipped some like the Momonga Hanger and used the casino as a curtesy out of respect for Momonga. Albedo then came up with an idea to liven the casino by hosting an event similar to what they did with LittleMass and Demiurge added to the idea by proposing the inclusion of limited-time items. 
The Pleiades maid was included to act in the organization of the event due to her closeness to the general maids. Both she and Lupusregina came up with plans and prizes for the "Rare Item Acquisition Day" event. For her contribution Lupusrgeina suggested that she and Albedo interact with the casino guests during the event and stir things up by cajoling the crowds. She particularly wanted to pay attention to Foire and Cixous as the two had a known rivalry going when it came to games at the casino. For the event Lupusregina was given a cat cosplay outfit from the Treasury.

Lupusregina and the rest of the Pleiades would be summoned by Momonga who wanted to select one of them to be part of an expedition to the Dwarf Kingdom to investigate the bathing customs of the dwarves. To the surprise of Lupusregina and her sisters it was Solution who willingly volunteered as the slime wanted to do some research on baths in her goal to become a bathing attendant.
Since the protagonist was going on the mission, and there was still worry that Enhela would target the homunculus, Momonga assigned Lupusregina to act as an escort. When the group left Nazarick and rested in the Great Forest of Tob, they met up with Hamsuke and Kyuko. Lupusregina in her worker costume, told her peers that she would be referred to as Regi for the duration of the mission. 
After picking up Zenberu to serve as a guide to the Dwarf Kingdom, she and her team reached Feo Jera where they began conducting their investigation. Said investigation then took them to Feo Berkana so that they could study the famed bathhouse only to h see it destroyed by the Frost Dragon. This resulted in Sebas beating the dragon as a form of discipline, which during the fight Regi commented the dragon to be weak as confirmed when Yuri told her when it fought Cocytus.

While in her worker identity, Lupusregina observed that Zero was allowing some former nobles escape through the Katze Plains. Later on she learned it was part of a greater ploy ordered by Emperor Jircniv. Zero had volunteered her and CZ to infiltrate an Anti-Imperial Faction rally to steal an item known as the Blood Oath. Given that the event was filled with nobility and Lupusregina's lack of etiquette, she was put in a training course under Yuri and Renner's guidance.
Despite complaining about the training, Lupusregina absorbed her lessons and managed to portray herself as a noblewoman. At the venue she impressed everyone with her false background, grace, dancing skills, and putting on a false face of supporting the rebellious group in their plan to oust Jircniv. When she was invited to sign her name on the Blood Oath, Lupusregina slit the throat of the guard holding the oath and stole it. She and CZ ran out of the venue to regroup with her worker colleagues who dispatched their pursuers. To celebrate their victory, New Six Arms went out for drinks. And to explain how she was able to appear and act as a noble, Lupusregina gave a story of a noble being indebt to her and training her in E-Rantel.

Her team was the first to arrive at the Lemegeton and was soon followed by Shalltear's team. They were greeted by Enhela who invited them into the Throne Room.
After Enhela failed once again to convince his brother, the protagonist, to join him, the priest took an aggressive stance. When Lupusregina saw that he transformed, she noted it was like the Chaos Adaptive Equipment, though Solution believed the similarity was the other way around.
In the fight against Enhela, Lupusregina employed herself by healing her allies. However she eventually exhausted herself, as Enhela came out unscathed from the multiple attacks from her allies. Lupusregina and her allies were helpless as Enhela, approached the protagonist, and the Pleiades was in shock after the priest murdered Solution when she attempted to stop him. 
After Enhela declared he would fatally attack the protagonist, Lupusregina thought he was insane, though the priest believed that it was a necessary move to awaken his brother to his true potential. When the protagonist awakened his abilities, but rejected the priest still, the other teams finally arrived.
