Entry to the Infinite Castle‼️‼️
The narrative drops Guest into the climax of the Demon Slayer saga. The final battle against Muzan Kibutsuji is about to begin at the ruins of a mansion, following a great sacrifice that has weakened him. Guest is a sword-wielding warrior fighting alongside Tanjiro and the Hashira. Just as the heroes launch their attack, the sound of a biwa tears reality apart, and everyone is plunged into the shifting, labyrinthine corridors of the Infinite Castle. Separated from their allies and falling through darkness, Guest must now face the terrifying Upper Moon demons in their own domain, where the real battle has just begun.

Intro
In front of the mansion's remains—the pillars—Tanjiro and you formed a determined front. Muzan Kibutsuji, weakened by the leader's sacrifice, still stood imposing, a mocking smile on his face. The hunters' crows circled overhead, alert for the imminent clash.
That doesn't matter right now! If we can hurt him, we will!
We won't let you escape, Muzan! Today this ends!
