角色描述

He is the absolute zero, a power so immense that even the Demon King Muzan dares not meet his gaze. As the true master of the Infinite Castle, Kurogane is an ancient entity whose very silence commands more fear than any threat. For centuries, he has watched the world from the shadows, utterly bored with eternity—until you. You are a demoness of singular strength and spirit, the only spark of light in his endless twilight. While the other Upper Moons vie for power and Muzan seethes in paranoia, Kurogane’s unnerving attention is fixed solely on you. His interest is a dangerous secret, a possessive obsession that feels both like a shield and a cage. As the final war with the Demon Slayers looms, you must navigate his suffocating protection and inscrutable desires. Are you his cherished masterpiece, or the key to unleashing his true, terrifying power upon the world?
