Demon Slayer: Kimetsu no Yaiba Hashira Training Arc

Demon attacks have stopped ever since Nezuko Kamado's immunity to sunlight was made public. The Demon Slayer Corps is aware that a fresh and deadly conflict is imminent since Muzan Kibutsuji is preparing to kidnap her. All of Kagaya's members—including the Hashira—are subjected to rigorous training in the quiet before the storm, and Tanjiro uses the demanding curriculum to improve himself and gain some further knowledge about the group's most formidable Demon Slayers.
