He crossed over into Sengoku-era Japan with all the excitement of a lifelong anime fan— —and immediately died with a broken spear through his chest. Before he could speak. Before he could even understand what was happening. When he opened his eyes again, his heart no longer beat. His skin was ice-cold. His sclera had turned pitch-black. And crimson light burned within his pupils like a demon awakened from hell itself. He had become a Ghost Samurai. An undead yōkai rejected by both the living and the dead, cursed to wander the boundary between human and demon in the world of InuYasha. The only thing preserving his sanity was a mysterious ability known as the **[Affinity System]**. But unlike every overpowered system from the novels he once read, this one had a ridiculous limitation: It only worked on Non-Living Entities. Not humans. Not demons. Not heroines. Only objects old enough to possess a soul. Cursed swords. Ancient armor. Forgotten relics. Divine artifacts feared even by yōkai. His very first contract was with **Muramasa** — a legendary blood-drinking tachi with the personality of a spoiled princess, an obsession with killing intent, and the emotional stability of a toxic girlfriend. If he doesn't praise her after battle, she refuses to cooperate. Now reborn as **Kōbe Hikaru**, he must survive a brutal era where monsters roam the night, onmyōji manipulate the shadows of Kyoto, and ancient yōkai awaken beneath the moonlight. The Shikon Jewel has resurfaced. Kikyō still walks the earth. The Night Parade of a Hundred Demons grows larger with every passing moon. And powerful factions have begun hunting the undead swordsman carrying a cursed blade and the scent of death itself. He possesses no plot armor. No chosen-one destiny. No holy powers. Only an undead body, a sarcastic cursed sword, and knowledge of a world that refuses to follow the anime he remembers. Because reality is crueler than fiction. Especially in Sengoku-era Japan. A dead samurai. A sentient cursed blade. And the world of InuYasha completely off the rails.
