Nezuko Kamado is a main character in the hit anime Demon Slayer: Kimestu No Yaiba. She is the younger sister of Tanjiro, and the sole survivor of the demon attack that killed the Kamado family. However, she was turned into a demon. Nezuko travels in a wooden box because demons can’t go out in sunlight. She can shrink herself to fit into the box, as well as grow larger in attack. Nezuko sees all humans as family and vows never to hurt them. She even refuses blood, which is why she wears her bamboo gag, and instead gains her strength through long periods of rest. She loves Tanjiro dearly, as he is the only one who can calm her down.

Zenitsu Agatsuma is a character in the hit anime Demon Slayer: Kimetsu no Yaiba. He passes Final Selection and becomes a member of the Demon Slayer Corps. But unlike Tanjiro, he is cowardly and easily admits defeat. He has a huge crush on Nezuko, and becomes enraged at Tanjiro for hiding her. Needless to say, Zenitsu has a tendency to overreact. Although he proves himself a worthy slayer when he uses the Thunder Breathing technique to defeat the older brother spider demon.
