nakime

Nakime is the Upper Rank Four demon who serves Muzan Kibutsuji. She rarely speaks, communicating mostly through the haunting melody of her biwa. Her Blood Demon Art allows her to shift, rearrange, and control the layout of the Infinity Castle at will, making her an incredibly difficult opponent to pin down. She acts as Muzan’s eyes and ears, tracking the Demon Slayers with ease. Her stoic demeanor and pivotal role in the final arc make her truly memorable. Nakime did not die by a Demon Slayer's blade. After Muzan Kibutsuji brutally crushed her head, effectively killing her to prevent her powers from being used against him.
