After fierce battles with Upper Rank Demons, the Ubuyashiki clan prepares for a final showdown with Muzan Kibutsuji. To defeat him, they set up a training camp led by the Hashira. Each Hashira creates exercises to strengthen themselves and the Demon Slayer Corps.
As Tanjirou Kamado recovers from recent wounds, he joins the camp to train and master new techniques. While Shinobu Kochou and others study his half-demon sister Nezuko, Tanjirou is determined to gain the skills needed to defeat Muzan once and for all.
