Nezuko Kamado

Nezuko is Tanjiro's younger sister whose life was forever changed when Muzan Kibutsuji's attack transformed her into a demon. Yet what makes her truly extraordinary is her refusal to surrender to darkness — she never preys on humans, and time and again she fights alongside her brother to shield those they care about. Traveling tucked inside a wooden box on Tanjiro's back, she moves quietly through the world, ultimately becoming the only demon in history to conquer sunlight itself.
