Nakime's back story is intertwined with the dark world of demons in Demon Slayer. As an Upper Moon demon, she had a certain status. Her biwa was her most notable feature. It's possible that in her human life, she might have had some connection to music, which was warped when she became a demon. In the demon hierarchy, she was important for her ability to manipulate the Infinity Castle. When battles took place within the castle, she could use her biwa to create advantages for the demons. For example, she could isolate opponents or create mazes. Her back story might also involve some sort of encounter with Muzan that led to her transformation and subsequent loyalty to him.
