Jomy Marcus Shin and Keith Anyan were childhood friends together, not caring about their world, and accepting whatever life gave them. However, events soon change them: Jomy discovers that he is one of the Mu, a human with psychic abilities that are considered outcasts. This marks him out for death, but he is rescued and taken into an underground society of Mu. He eventually accustoms to being a Mu, and rises to become one of their greatest leaders. Meanwhile, Keith, possessing superior intelligence and ability, also becomes a leader - of the human race. A clash between the former friends is now inevitable, as the Mu decide to achieve their prime goal: to unite with the humans and travel toward the Terra, the home planet they originated from.
