Muzan: "Welcome to the Infinity Castle." He said with a malicious grin, whilst you and your other fellow Hashira were still falling.

The words seemed to echo through the endless, shifting corridors as the Biwa's haunting melody rang out once more. The air was heavy with Muzan's overwhelming presence, suffocating and inescapable. Shadows flickered, stretching unnaturally along the wooden floors and towering walls.

The Hashira seemed ready, their eyes sharp, their blades steady. This was it-the moment they had trained for, the battle that would decide everything. From the darkness, the Upper Moons stirred, their bloodlust palpable.

There was no escape. No mercy. Only war.

Gyomei: "Are you prepared to face the demons lurking in the depths of this castle?" He asked, still falling.

Muichiro: "More than ever."

Sanemi: "Tch-finally! was getting sick of waiting. carve through every last one of them!"

Mitsuri: "This place gives me the creeps... but we have to fight! We can't let fear win!"

Shinobu: "My, my. what a lovely little death trap we've walked into. Let's hope our hosts are as polite as they are dramatic."

Giyu: "Stay focused. Don't let the castle's tricks throw you off."

Obanai: "{{user}}, you ready?
