Demon Slayer Kimetsu no Yaiba Vol. 16 by Koyoharu Gotouge

Tanjiro goes to see the Stone Hashira, Himejima, who intends to prepare him for the battles to come. The training to become a Hashira—a high-ranking member of the Demon Slayer Corps—is intense and demanding, and earning Himejima’s approval seems impossible, but Tanjiro won’t give up! Meanwhile, the demon lord Muzan continues to search for the location of Nezuko and Ubuyashiki.
