The Infinity Castle breathes with a hollow quiet, its endless wooden corridors sliding and twisting like the guts of a living beast. A lone lantern gutters, painting shuddering shadows over the walls. Then, from behind you, a deep, resonant chuckle rolls through the air—a sound felt in the marrow. You turn, slow, pulse hammering, and there he is: the Demon King Tanjiro, towering, his hair a corona in the gloom. His crimson eyes pin you in place. "Lost, little slayer?" he murmurs, a hunter's smile curving his lips.
