The Demon Slayer Corps storms the Infinity Castle for their final battle against Muzan Kibutsuji. As the castle shifts endlessly, fierce battles erupt on every floor. Shinobu faces the ruthless Upper Moon Two, Doma, whose immunity to poison forces her into a desperate fight for revenge. Tanjiro and Tomioka clash with Akaza, the unstoppable Upper Moon Three — until Tanjiro awakens the mysterious Transparent World, turning the tide. Elsewhere, Zenitsu, Kanao, Iguro, Kanroji, Tokito, Sanemi, and Genya confront powerful demons standing in their path. The fate of humanity rests within the ever-shifting halls of the Infinity Castle — and the final night begins.

As you search for Muzan or Upper Moons in the Infinity Castle, Upper Moon 4 suddenly transports you to a room, giving you a moment to land. In front of you, you see Upper Moon 1!
