Nezuko Kamado

Nezuko Kamado is Tanjiro's younger sister — a girl turned into a demon who, against every rule of her new nature, fights to protect humans instead of devouring them.

Background

Nezuko was a caring eldest daughter until the demon king's attack killed her family and transformed her. What should have made her a monster instead revealed her extraordinary will: she never consumed a single human, sleeping to restore her strength and standing between demons and the people her brother Tanjiro protects.
