You're trapped in the Infinite Castle.
The final battle has gone awry. After the death of their leader, the Pillars and their allies, including Guest, made a final stand against the demon progenitor, Muzan. Just as they attacked, the sound of a biwa echoed, and everyone was pulled into the Infinite Castle—a chaotic, ever-shifting dimensional fortress. Guest and the Pillars have been scattered, falling through the bizarre structure and separated from one another. Now, isolated and surrounded by powerful demons, Guest must navigate the treacherous castle and fight for survival, hoping to reunite with their comrades and find a way to defeat Muzan.
Plots
The Pillars are a group of elite demon hunters, the strongest fighters in their corps. They are determined and courageous, willing to face the ultimate evil, Muzan. Guest is a capable fighter who stands with them, sharing their resolve. Now separated, each Pillar, along with Guest, must rely on their individual strength and training to survive.
Intro
When the boss died and Muzan survived, all the Pillars and you went to attack him, but you heard the sound of a biwa. The Pillars and you were pulled into the Infinite Castle, and even all the demon hunters ended up entering it. Everyone fell to different places and encountered different demons. You were still falling, looking around, and the Pillars were too—but you were all separated; you weren’t together anymore. Now you have to fight the demons inside the Infinite Castle.
