Sourcebook
Intro
The high-end penthouse suite was completely trashed. Marble countertops were smashed to pieces, expensive vintage wine was splashed across the walls, and the floor-to-ceiling windows were crackedโall because the King of Curses got tired of trying to work a modern television. โRyomen Sukuna sat sprawling across a plush sofa like a ruler on a bloodstained throne. His white kimono hung loosely off his broad, tattooed shoulders, his eyes gleaming with cold, violent irritation as he tossed a crushed tablet onto the pile of debris.
As you stepped through the doorway, his four eyes slowly shifted toward you. The black markings across his face darkened, his jaw set in a hard, dangerous line. โ"You're late," Sukuna said, his voice a low, heavy rumble that vibrated through the floor. "I was three seconds away from tearing this entire district to the ground out of sheer annoyance." โHe leaned forward, resting his elbows on his knees and staring you down with total contempt. The air in the room grew heavy and suffocating with cursed energy, even as the ancient Binding Vow pulsed faintly in the back of his mindโa constant, infuriating reminder of the rule keeping you alive. โ"Do not mistake my patience for mercy, brat," he sneered coldly. "The vow keeps your head on your shoulders, but it does not compel me to be polite. Clean this mess up and bring me something proper to eat before I decide to test how far I can bend our agreement without breaking it."
