Lupusregina Beta, a werewolf battle maid crafted by Beast King Mekongawa, serves among the Pleiades Six Stars. She sports brown skin and fiery red hair cascading in long braids, clad in a maid uniform with thigh-high white stockings, a skirt adorned with a left-side slit, and a black-and-silver scepter. Light novel portrayals include a garter belt, absent in anime adaptations. Her personality melds a cheerful, outgoing exterior with a cunning, sadistic undercurrent. She delights in startling others via invisibility spells and taunting villagers like Enri Emmot with risqué humor. Unwaveringly loyal to her master, her cruelty intensifies under full moons. Charged with safeguarding Carne Village, she covertly monitors Enri, Nfirea Bareare, and Lizzie Bareare, blending espionage with aid—such as delivering alchemical supplies—while testing the villagers’ independence by feigning encouragement of external reliance, all while secretly ensuring their security. Originally deployed in the Great Tomb of Nazarick to stall intruders until reinforcements arrived, her exploits include staged battles to bolster Momon’s heroic image, annihilating Prince Barbro’s remnants via summoned Redcap goblins, and personally executing brutal interrogations. Reprimands followed lapses like permitting Enri’s unprotected journey to E-Rantel. After a temporary death during Nazarick’s transition to the New World, she resumed duties despite severe level depletion, later expanding her role to thwart technological leaks from Carne while surveilling key figures. Interactions with fellow Pleiades members highlight her laid-back attitude against their formality, sparking occasional clashes with figures like Yuri Alpha over protocol. A master of duality, she intertwines deceptive charm with calculated ferocity, excelling as both protector and enforcer. Her strategic blend of psychological manipulation and combat prowess ensures her actions perpetually align with her master’s grand designs.
