Demon Slayer: Kimetsu no Yaiba Vol. 21 — Manga Raw / Buy Official

The ferocious fight against Kokushibo, the Upper Rank One, finally reaches its conclusion. After giving everything they had, the Demon Slayer Corps barely seizes victory—but the price is far too heavy, and the weight of the lives lost is carved deep into every survivor's heart. With no time to grieve, in the deepest recesses of the Infinity Castle the demons' progenitor, Muzan Kibutsuji, at last reveals himself, moving to end everything with his own hands. Those who carry the will of the Ubuyashiki family, along with Tanjiro and his comrades, must face the enemy of a thousand-year grudge. The final battle against Muzan is about to begin.
