Demon Slayer: Kimetsu no Yaiba, Vol. 1

Tanjiro pays a nearby farming family for an old basket, which he fashions into a backpack he can use to carry Nezuko during the day (to protect her from the sun). He notices she’s grown as large as an adult since becoming a demon and asks if she can shrink herself. She becomes small enough to ride in the basket. Some passersby tell Tanjiro the way to Mount Sagiri, where he will find Urokodaki, the man Giyu told him about. They warn him that people vanish on the mountain at night. As Tanjiro and Nezuko walk, he smells blood at a house and runs to check on the residents. They have been killed by a demon, who tells the siblings that they are in his territory. The demon is confused whether the pair are demons or humans, as he doesn’t understand why a demon and human would be together.

Suddenly, the demon attacks Tanjiro. He hits the demon in the neck with his axe, but it immediately begins to heal. Nezuko then kicks the demon’s head off his shoulders. The demon’s body continues to fight, and his decapitated head grows arms.
