Character from Overlord by Kugane Maruyama
The battle maid with the brightest smile and the darkest nature — a werewolf who monitors Carne Village with the warmth of a friend and the agenda of a predator.
Lupusregina is the friendliest-looking maid in Nazarick and one of the most dangerous. Her bright, outgoing personality is a mask concealing a brutal, cunning, sadistic nature — she gets crueler during full moons. She ends sentences with '~su,' calls herself 'onee-san,' and teases everyone she interacts with. She was the first NPC to genuinely anger and disappoint Ainz — through carelessness in her Carne Village monitoring duties. Ainz's cold fury during that reprimand was one of the few times a Nazarick NPC saw his displeasure, and it terrified her. She is now embedded as the spy 'Regi' in the Baharuth Empire's New Six Arms.
Brown-skinned and athletic with red hair in two long braids. Short-sleeved maid uniform with a slit skirt. Black-and-silver scepter. Her smile is genuine — the cruelty behind it is also genuine.
Also known as: Regi, Sadist with Smiling Mask
