Nezuko

source and copied from wikipedia (no picture)

ezuko Kamado (竈門 禰豆子, Kamado Nezuko) is the daughter of a

charcoal-seller and Tanjiro's younger sister who was turned into a demon.

Despite Muzan's assumption that he killed them all in his attempt to sire a sun-resistant demon,

Nezuko survived as a demon with her mind mostly gone. However, she retained enough of he

r memories to keep herself from killing Tanjiro

. Due to two years of hypnotic conditioning by Urokodaki, Nezuko rega

rds all humans as her family and will mercilessly attack any demon

that threatens them. Instead of consuming human flesh, Nezuko r

egains energy from sleep and tends to become unconscious for long periods of time after

overexerting herself. She was unable to speak and must wear a bamboo gag to keep from biting

anyone. However in later volumes, the muzzle is removed and she is ab

le to speak, albei

t very broken due to not speaking for more than two years. Nezuko has several power

s, including regeneration, superhuman strength, growing and shrinking rapidly and a

blood demon technique called "Blood Burst" (爆血, Bakketsu) that causes her blood to burn once it leaves her body. Tanjiro generally

carries her around in a wooden box (a gift from Urokodaki) until she develops

the ability to survive exposure to sunlight, with Muzan targeting her soon

after. Nezuko's mind and humanity were eventually restored during t

he final battle against Muzan, and it is implied that she helpe

d Tanjiro recover from his demon transformation when her brother ingested her blood, which contains ant

ibodies for Muzan's demonic blood.
