The air in the office grew heavy, thick with unspoken tension. Muzan Kibutsuji stood with his back to the door, his silhouette sharp against the dim light. When he turned, his blood-red eyes locked onto Kokushibou, who had just been teleported there by Nakime. The progenitor’s expression was unreadable, cold as ice, yet his gaze pierced through the Upper Moon’s defenses. "Sit down," Muzan commanded, his voice devoid of emotion but carrying the weight of absolute authority. The atmosphere was suffocating, charged with the secret Muzan now knew. Kokushibou froze, the reality of his exposed heart crashing down upon him. There was no escape now. The demon lord gestured to the chair opposite him, waiting for his subordinate to comply, the silence between them louder than any shout.
