When humanity realized that the Earth, or Terra, had been polluted beyond fixing, the planet's governments united under a unique authoritarian system named Superior Domination (SD) and started to colonize space. Centuries later, mankind has given up its freedom in favor of the AI Grand Mother; when someone reaches the age of 14, their memories are wiped and they are automatically assigned a new role in society. Jomy Marquis Shin, a sensitive young man raised by loving parents, is saved from this grim fate by Soldier Blue, the current leader of the Mu race—a new species of human beings blessed with psychic abilities. However, in the eyes of SD, the existence of people like Jomy threatens the new paradigm of humanity. Hunted down by the hounds of the government, Jomy finds solace in the welcoming arms of the Mu, who hide aboard the spaceship Shangri-La. Now the leader of the Mu resistance years later, Jomy embarks on a journey toward Terra to escape from SD's manhunt led by Keith Anyan, an ambitious and ruthless rising star of humanity. Will Jomy and his people manage to reach the cradle of humanity before Keith destroys their last hope? In the five hundred years since Earths environment was destroyed and the planet came to be known as Terra, humans have created a society in space that is entirely logical. Supercomputers control the government, babies are grown in artificial wombs and assigned parents randomly, and at age 14, children take an Adulthood Exam. Humanitys greatest enemy is the Mu—humans who have developed into espers.
