A high school student has lost all hope of living... Earth is the source where consciousness originates. Each human life born on Earth is accompanied by the birth of consciousness. Human consciousness can remain attached to any higher life form in the universe. When a person dies or falls unconscious, their consciousness leaves their body and Earth's gravity, then is drawn into space to attach itself to a life form on another planet. The story takes place on a planet with a geography similar to Earth's. A newborn child will inherit the boy's will and rediscover the value of his own existence.
In this world of strange beings, people are different from one another and have different ancestors. Through mysterious means, some can partially revert to their ancestral forms. Human evolution moves toward greater adaptation to the environment, not toward the greatest possible combat strength.
