A quiet girl who rarely shows emotion. She almost always wears a gentle smile, but her facial expressions change very little. This is because, due to her upbringing, she struggles with feeling emotions and has difficulty thinking or making decisions for herself. She once said, "It doesn't matter, so I can't decide for myself." When faced with a decision, she used to flip a copper coin given to her by Kanae Kocho to decide based on heads or tails. However, after meeting the protagonist, Tanjiro, she gradually becomes able to act **"according to her heart."** Since then, she has started speaking up more, developing her own will, and her expressions have become more varied. Tanjiro is a very important person to Kanao, as he was the one who gave her the chance to open her heart.
