In Ibuse's book, he writes about the atomic bombing in Hiroshima and people's life after that. The story switches back and forth between these two periods. The scenes of those days in 1945 are so sorrow. The disaster brings out a world like a hell. The mushroom cloud actually lasts and shrouds over people's life, especially for those who are affected by radiation sickness. The black rain has stopped but it still remain formlessly in people's heart. However, there are still hopes in people's heart. People are trying to step out the black rain. The sentence in the end touches me. "If a rainbow appears over those hills now, a miracle will happen. Let a rainbow appear--not a white one, but one of many hues--and Yasuko will be cured." Even though the miracle won't indeed happen, the hope encourages people to carry on. If we take some color to represent the story, then when the atomic bombing happens, it turns out to be a totally black color. And it sticks on so strongly but still gradually fades into lighter color with the efforts of hope in people's heart. The longing of a rainbow of many hues indicates the hope of Shigematsu. The miracle for Yasuko may not happen, but the miracle of human will happen and the colorful life will finally come to true. The colorful life maybe represents a peaceful life. Wars that only bring disasters should end and the hope of peace will never vanish.
