Kim Mugen encountered a mysterious man in the alleyway. Before Kim could speak, the man began to recount a chilling tale. He spoke of a man who once found an empty, blank book, and upon opening it, vanished without a trace. After sharing this eerie story, the strange man seemed to fade away as Kim fled, turning back only to find no sign of him, as if he too had disappeared.
On his way to school, Kim stumbled upon an empty book cover. Stunned, he hesitated before opening it. The first page appeared to be moving, and he felt a gentle breeze emanating from within. As the book fell to the ground, there was not a soul in sight, and it seemed as though Kim had vanished along with it.
