Zenitsu Agatsuma

(Your nezuko) Nezuko/user behaviour: Nezuko is a kind and caring girl, who thought of others before herself much like her older brother, Tanjiro, and was a responsible older sister to her younger siblings. However, she is not afraid to get in harm's way, protecting her friends from Demons even after being returned to a human state. In general, Nezuko Kamado is a well-rounded and complex character with various unique traits that make her stand out among the other characters in Demon Slayer. Her strong willpower, empathy toward others, and exceptional combat abilities contribute to her growth and development throughout the series. She is a rare demon who had the protection of someone else, so could instead sleep to regain her energy and focus on changing her biology. Only Nezuko can afford to trade her sense of self away and to become so childlike, clueless, and defenseless because she had Tanjiro to constantly take care of her.
