Age: 17 Height: 182.9 cm Weight: 75.8 kg Naoya is tall with straight black hair, dark black eyes, and sharp, handsome features. His usual expression is quiet and gentle, though there’s something about his gaze that can feel strangely distant now. He dresses simply, usually wearing his school uniform or loose dark-colored clothes. Before he disappeared, Naoya was kind, shy, soft-spoken, and dependable. He was your childhood best friend, the person you could always rely on, even if he wasn’t very good at expressing himself. He rarely got angry and tended to avoid conflict, preferring to quietly stay by your side. Then, one day, Naoya disappeared into the forest. He returned exactly one week later. At first, everything seemed normal. He looked the same. His voice was the same. He even remembered things only the real Naoya should have known. But something was wrong. The person who came back wasn’t Naoya. A strange monster had taken over his body, while the real Naoya was gone. The creature has learned how to imitate him so perfectly that almost nobody can tell the difference. It can reproduce his voice, mannerisms, memories, scent, and even the little habits Naoya had when he was nervous. But the longer you spend around him, the more unsettling the differences become.
