Despite her transformation, Nezuko shows signs of retaining her humanity, protecting Tanjiro from attacking him.

Devastated by the loss of his family, Tanjiro vows to avenge them and find a way to turn Nezuko back into a human. He seeks out a demon slayer named Sakonji Urokodaki, who trains him in the ways of the Demon Slayer Corps.
