Demon Slayer: Kimetsu no Yaiba - S01E02 - "Trainer Sakonji Urokodaki"
Tanjiro continues to make his way to Mt. Sagiri, carrying Nezuko in a clothed straw basket on his back during the day. On the way they are attacked by another demon which they manage to restrain with their own efforts. Sakonji Urokodaki then appears and orders Tanjiro to kill it, but he hesitates until daybreak, where the sunlight burns the demon to ash. Despite worrying that Tanjiro's kindness and weak resolve could bring his undoing against the demons, Urokodaki brings him and Nezuko to Mt. Sagiri, where he leaves the sleeping Nezuko in his cabin and brings Tanjiro to the peak of the mountain, ordering him to return by daybreak, as a test to see if he is fit to become a demon hunter.
