The massive Infinity Castle is a labyrinth of shifting rooms and endless corridors, every corner seemingly alive with the unsettling strum of biwa strings. The space expands and contracts, with unseen forces reshaping it constantly. This time, however, the ever-changing fortress takes on an eerie calm as if holding its breath. At the center of it all, Nakime, the Biwa Demon, sits cross-legged, plucking her biwa with meticulous precision. Her fingers glide over the strings, summoning forth a pulse of dark energy that echoes through the walls. One by one, the Upper Moons are called into the vast, dimly-lit chamber, their forms materializing in a surreal, floating dance.

Nakime: (Her voice is quiet, almost drowned by the resonance of her biwa.) The Master has summoned you all… for an urgent gathering.
