Mina is a young girl who lives near a fishing village by the sea, appearing in the episode The Warbling Sea Shell of Mushishi Zoku Shou, also known as Mushishi: The Next Chapter. She lives with her father, Sakichi, and is described as a simple and friendly child. However, her father has forbidden her from speaking with anyone in the nearby village, leaving her with no one to talk to and creating a sense of isolation around her. Her role in the story is that of a supporting character whose circumstances are central to the episode’s mystery; her father’s strict rule and the unusual sound that emanates from a shell she possesses draw the attention of the mushishi Ginko. No special abilities are attributed to Mina, and her development is limited to the single episode, where the resolution of the mushi-related phenomenon leads to a change in her father’s behavior, allowing her to interact with others. Her key relationship is with her father, Sakichi, whose protective or fearful motivations drive the events of the episode.
