As Tanjiro and the others are devoted to their rehabilitation training, the absolute master of the demons, Muzan Kibutsuji, gathers the Lower Ranks of the Twelve Kizuki. The demons, too, are preparing to make their next move. As training draws to a close, Tanjiro has improved to the point where he can fight on equal terms with Kanao. Just then, he receives word of a new mission from his Kasugai Crow.
In the anime, Giyu arrives at the Butterfly Mansion to visit Tanjiro before he sets off on his mission. However in the manga, it does not mention Giyu visiting Tanjiro, and only depicts the boys bidding the girls farewell.
