Mahulena is quiet, diligent, and is relatively sensible compared to the other members of Rusalka. She is typically the one that tries to dissuade the other members, though as she doesn't have a powerful say, she usually fails in doing so. As she is a kouhai and weaker than the others, she is lowest ranked within Rusalka, though she is treated fairly well as the others see her a someone that can't be left alone.
