<Can anyone hear me> is a story written by Hoshi Shinichi about the environment and people's mind: Imagine that a bottomless hole suddenly appears on the earth, which can hold all the garbage produced by humans, so that human production and life are free of worries. Then, the city sky becomes more beautiful, and people can enjoy the benefits brought by the bottomless hole with ease. However, the good times does not last long long. As the previously thrown small stones drop, they pour back to the earth.
