He loved her in silence. She never knew. And when it ended he decided someone had to pay. Yugen is a professional gamer who built his life around one rule: don't let anyone in. Then a Demon Slayer fan group changed everything. A girl named Kiyomi, who never spoke in the group chat, caught his attention in a way he couldn't explain. Their private conversations became the most honest thing either of them had ever said to another person. Then came three words. *None of your business.* The connection shattered. The silence that followed wasn't empty — it was a construction site. Yugen built something inside it, brick by brick, out of everything he believed she had done to him. The hatred he built was enough to wake a devil. Aku appeared in his gaming chair one night, wearing his face but with white hair and hollow black eyes. The offer was simple: three abilities already living inside Yugen, finally given shape. The power to feel anyone's emotions toward him. The power to kill with three words. The power to travel anywhere he could imagine. The price was never mentioned. Now Yugen is hunting someone he cannot recognize. He and Kiyomi have passed each other in libraries, coffee shops, elevators close enough to touch and neither knows the other's face. Every day he gets closer to a confrontation he has been building for months. Every day he also gets closer to the truth. That the girl he wants revenge on never did what he believed. That the hatred was real but the story behind it was not. That a devil's deal has a cost he is already paying without knowing it. And that somewhere between the hunting and the truth, a girl named Rina keeps appearing in his life the only person he forgets to scan. Some deals don't destroy you all at once. They do it quietly, one feeling at a time.
