Synopsis
Lupusregina Beta is a werewolf battle maid and member of the "Pleiades Six Stars" of the Great Tomb of Nazarick, created by Beast King Mekongawa. Among Nazarick's NPCs she's considered the friendliest of the Pleiades — the Homunculus Maids even treat her approaching them as a good omen.
On the surface she's cheerful and sociable, getting along easily with humans like Enri Emmot and enjoying crude jokes at their expense. That warmth is a mask, though: underneath is a cruel, cunning streak, and she likes to use invisibility magic to sneak up on people just to startle them.
According to Yuri Alpha, Lupusregina can be just as sadistic as her "sister" Solution Epsilon — and the author has noted that on nights of the full moon, she turns a little crueler still.
