Plot: A Final Descent into Darkness
Here’s the official synopsis, provided by Sony:
Tanjiro Kamado, a boy who joined the Demon Slayer Corps to save his demon-turned sister Nezuko, has grown stronger through fierce battles and deepened bonds. Alongside his loyal friends Zenitsu and Inosuke, he has fought demons alongside elite Hashira like Rengoku, Uzui, Tokito, and Kanroji.
As the Corps prepares for its ultimate confrontation with Muzan Kibutsuji through intense Hashira Training, Muzan strikes first—launching an attack on the Ubuyashiki Mansion. Tanjiro and the Hashira rush to defend their leader, only to be plunged into a strange dimension by Muzan’s power.
They land inside the Infinity Castle, the demons’ stronghold. There, the stage is set for the decisive battle between the Demon Slayer Corps and the forces of evil.
