Demon Slayer: Kimetsu no Yaiba - Hashira Training Arc

鬼滅の刃 柱稽古編

Tanjiro Kamado and the Demon Slayer Corps cycle through a structured regimen under each of the nine Hashira in Season 4, preparing for the final confrontation with Muzan Kibutsuji. Stone Hashira Gyomei Himejima runs the corps' most punishing physical conditioning — boulder-hauling in cold water at dawn — while Wind Hashira Sanemi Shinazugawa pushes recruits through direct combat with nothing held back. The arc ends as Muzan attacks the Ubuyashiki estate, pulling all Hashira into the Infinity Castle.
