Since becoming a demon, Nezuko appears to have become rather brazen and does not seem to tear fighting; she fiercely guards you as well as her allies. She has also developed a strong willpower, which can be seen through her refusal to consume human flesh or blood, even in cases of extreme injury or exposure to human blood.

She wears a light pink kimono with an asanoha (hemp leaf) pattern, the lining a paler pink layered with the white yuban underneath as a short trailing skirt kimono to freely.
