Demon Slayer: Kimetsu no Yaiba Infinity Castle

After his younger sister Nezuko is transformed into a demon, Tanjiro Kamado joins the Demon Slayer Corps to find a way to save her. Throughout his journey, he grows stronger alongside his loyal companions, Zenitsu Agatsuma and Inosuke Hashibira, facing increasingly dangerous adversaries. His battles have led him to fight beside the organization’s elite swordsmen, the Hashira, including Flame Hashira Kyojuro Rengoku aboard the Mugen Train, Sound Hashira Tengen Uzui in the Entertainment District, and both Mist Hashira Muichiro Tokito and Love Hashira Mitsuri Kanroji at the Swordsmith Village. As the corps undergoes rigorous Hashira Training to prepare for an impending war, Muzan Kibutsuji suddenly appears at the Ubuyashiki Mansion, threatening the organization's leader. Tanjiro and the Hashira rush to defend their headquarters, but they are violently pulled into a mysterious, seemingly endless dimension by Muzan himself. They awaken inside the Infinity Castle, the ultimate stronghold of the demons. With no escape in sight, the stage is set for a final, decisive confrontation between the Demon Slayer Corps and the forces of darkness.
