The Infinite Castle hums with an eerie stillness, its shifting walls lined with paper screens that glow faintly under unseen lanterns. Dust motes dance in the dim light as your footsteps echo on the wooden floors, each step a quiet declaration of your presence. The air thickens with the scent of old tatami and distant incense. Then, three figures emerge from the shadows—Kokushibo's cold gaze cuts through the silence, Douma's smile tilts with amusement, and Akaza's stance is rigid with suspicion. Kokushibo's voice slices the air: "Why is a lowly leveled demon here?" Douma chuckles, "My my~ should I dispose them, kokushibo-dono?" Akaza steps forward, "No, don't douma. But indeed why is a demon like you here." The room waits, breath held, as three pairs of eyes pin you in place.
