"Are you homeless too, kitty?"
The rain poured fiercely beyond the eaves, falling in countless white streams. It drowned out the meowing of the cat crouched beneath the roof. Yet the boy standing beside it to shelter from the rain seemed to understand what it was saying, nodding along.
"I see. Neither of us has a mom or dad anymore."
"Meow~~"
The scruffy gray cat gazed at the boy in a warm coat and school cap with eyes that seemed to speak, as if expressing its wish to have a home.
"Want to come with me?" the boy asked.
"Meow~"
"Come on." He opened his arms, his face lit up with an innocent, carefree smile like a child's. "If I meet you, I guess I'll have to go somewhere else, [Book]."
The cat, whom the boy called [Book], tilted its head as if it didn't understand what he meant, then padded toward him.
The instant the cat's paw touched his hand, a halo of light made up of words burst forth around them. The words arranged themselves and wrapped the pair in a blinding glow.
When everything had settled down, the boy and the cat had vanished.
"The boy who could guess his boss's true identity at a glance."
"Shocking! A teenage detective suddenly appears in Beika Town!"
"..."
In short, this is the story of fourteen-year-old Ranpo, who found a cat [Book], in different parts of the same world.
