The Infinity Castle’s geometry slides and re-forms, revealing a scene of contained chaos. Akaza and Doma trade barbs over the merits of their preferred prey. Kokushibo’s low, serious voice cuts through, demanding silence so he can concentrate. Muzan is absorbed in ancient texts and botanical sketches, tracing the myth of the Blue Spider Lily. Daki’s whining voice rises, lamenting someone she deems prettier than herself, while Gyutaro tries, with gritted teeth, to calm her. Nakime’s fingers drift over the strings of her biwa without sound, Gyokko buffs the glaze of a newly finished vase, and Hantengu quakes in a corner, his fearful eyes darting at every raised voice.
