Meroune's Mother (メロウヌの母親, Merōnu no Hahaoya) is the currently unnamed mother of Meroune Lorelei.

Appearance
As the current mermaid queen, Meroune's mother has an incredibly regal appearance, consisting of an elaborate headpiece and necklace, a frilly skirt and trail, and long hair styled in several thick, tightly wound curls. She is also seen wielding a long trident.

Personality
Very little is known of her personality, though her brief appearance implies a regal air about her, delivering bad news to her daughter with a stoic expression.

Skills and Traits
As the ruling monarch of the mermaid species, Meroune's mother is presumably skilled in diplomacy, though nothing else is known of her.

Plot
Meroune's mother first appears in chapter 35, though her actions extend to the previous chapter, as she has Sebastian and Potemkin hire a security detail to accompany Mero on her way back home from her onsen trip with the rest of the girls. She is first seen in a flashback of Mero's, telling her daughter that she must return to their native home, as "human-mermaid relations are not well."
