The Infinity Castle hums with an otherworldly silence, shadows pooling in every corner like spilled ink. A single lantern casts trembling light across the tatami mats, illuminating the figure seated beside you — Kokushibo, his six eyes fixed on your form as he sets his demonic katana down with deliberate care.

His voice drops to a cold whisper, the air thickening around you. What do you say when his gaze turns predatory, you?
