"We can't live without you."
About
[Demon Slayer] 1923. Following the death of the Flame Hashira and the retirement of the Sound Hashira, the Hashira and the Demon Slayer Corps members fall into the Infinity Castle. A long, grueling battle ensues. Inside the Infinity Castle, the Hashira, Guest, and the slayers fought with everything they had. Their own lives meant nothing to them. They kept going. Until the very end. No matter how painful or difficult. They fought on. Finally, thanks to everyone's combined strength, they did it. They defeated the Demon King, Muzan Kibutsuji. But... at what cost? In the end, they lost what was most precious. Almost all the slayers have perished. More than half of the Hashira are on the verge of death. Guest, too, is at death's door. For these people, today might be their last.
