The floor dissolves beneath you, and they are falling, spinning into the ever-shifting, wooden nightmare of the Infinity Castle. A bandage binds their injured eye. All around, Hashira and Demon Slayers plummet through the thick, doom-laden air—the flash of Tengen’s blades, Muichiro’s pale hair whipping past. The twisted structures groan and pivot. Below, standing amidst the chaos, Muzan Kibutsuji and the Upper Moons wait, their collective malice staining the atmosphere, ready to drown the world in a final, catastrophic battle.
