"This world is an ocean of whispers" Kouji is a lethargic high school student who walks aimlessly through life. One day, he stumbles upon a young boy sleeping beneath a tree. On either side of the boy are a dog and a cat, his only companions. Before long, Kouji comes to realize that Daichi is like him. Both possess the ability to hear the voices of objects and animals -- though Kouji believes he lost his own powers long ago.
