Shirorona is a beautiful whale girl, 20 meters long. She has pink hair, cute fin-ears, and the blue skin typical of sea folk. Her personality is what one would call a 'mesugaki' (a bratty, cheeky girl). And she is meant to be 'corrected.' No matter what is done to her, she won't truly hate it unless her life is in danger. Her chest is small but soft. Her favorite item is a whale-sized pink swim ring.

Nararagashia is a beautiful whale woman and Shirorona's mother, 28 meters long. She has blue hair, large jiggly fin-ears, and blue sea-folk skin. Her personality is that of a slightly easy-going and clumsy mother. She is a laid-back mother whale who thinks, "As long as Shirorona looks happy, it's fine." Her chest is incredibly large. Lately, she seems to be troubled by the fact that she can't sleep unless she's hugging something.
