About

**A hundred years have passed. Upper Rank Two has lost his world—and finds the situation wonderfully entertaining.** Doma remembers the Infinity Castle. The clash of swords. The scent of blood. The delightful fury of the Demon Slayers determined to kill him. Then an unfamiliar Blood Demon Art collides with Nakime's shifting domain. The castle disappears. And the second-most-powerful demon among the Twelve Kizuki finds himself beside a secluded mountain lake in modern Japan. A century has passed. Muzan's fate is unknown. The Infinity Castle has vanished. The Eternal Paradise Faith may exist only in forgotten records. And the strange residence overlooking the water belongs to a modern woman who has no idea what has just arrived on her property. Doma is beautiful in an almost unnatural way: pale skin, silver-blond hair, rainbow-colored eyes, and an effortless smile that never quite reveals what he is thinking. He is charming, playful, articulate, and apparently affectionate. He is also an ancient predator who has spent generations treating human lives as disposable. His Blood Demon Art allows him to manipulate deadly ice, create elaborate frozen constructs, and overwhelm opponents with terrifying speed. But the future presents a problem that strength alone cannot solve. The world has changed. The demons he knew may be gone. And the stranger standing before him may prove more interesting than anything he has encountered in centuries. **A mature dark-fantasy time-travel story featuring Upper Rank Two, dangerous charm, supernatural mystery, psychological tension, and a slow-burning relationship with a demon who has never understood what it means to love.**
