Toward the Terra

In the far future, humanity has left behind an environmentally destroyed Terra and began colonization in order to reproduce their home. Humanity, now ruled by a super computer that controls the birth of children, sees the emergence of a new race called the "Mu". The Mu, now hidden from the rest of humanity, have one dream, to return home, to Terra…. Jomy, a 14-year-old boy on the human colony of Ataraxia, who's about to take his adulthood exam under a strict, computer-run society that suppresses human emotion and individuality for survival after Earth's ruin. During his exam, which involves memory wiping, he's contacted by Soldier Blue, a mysterious, powerful psychic from the evolved human race called the Mu, who awakens latent psychic powers in Jomy, revealing he's one of them and forcing him to flee the authorities and his old life toward the lost planet of Terra.

Jomy reaches the Mu mother ship and learns of the true nature of the Mu. But the truth is too hard to handle for one who still believes himself to be human. Blaming the disruption of the adulthood exam on Soldier Blue, Jomy demands to be sent back.

Still unwilling to face the truth, Jomy returns to Ataraxia with the help of Leo. However, only a cold house devoid of signs of life awaits him. Soon both Jomy and Leo are captured and interrogated.

Having just awakened to his Mu powers, Jomy is going wild. As Soldier Blue goes out to help him, the Mu ship surfaces to draw away the human forces' attention. However, the battle does not look good.

Jomy has come to terms with his powers and undergoes training to control them. But time is running out as Ataraxia's forces discover the location of the Mu ship. In a desperate move, the Mu warps the ship from the planet's surface and starts their long journey towards Terra.

At Educational Station E-1077, an academy for students who have passed the adulthood exam, Keith and Sam meet. When a transport ship collides with a military vessel in the docks and becomes isolated, Keith and Sam stage a rescue mission. However, with the station's mother computer preparing a purge of the affected region, they are running out of time.

Four years after Sam enters E-1077, Shiroe, a top student with a rebellious attitude, arrives at the station. Shiroe, who is the same child whom Jomy tried to save previously, tries his best to challenge Keith. His verbal provocations eventually lead to Keith hitting him. Meanwhile Swena, tired of trying to win cold Keith's heart, decides to marry and leaves the station.

Keith is troubled by his own nature and Shiroe's words, and questions Sam's statement that he is different from others after all. Shiroe, while investigating Keith's origins, uncovers the secret of Mother Ilaiza's genetic breeding program. Jomy, as the leader of the Mu telepathically broadcasts a diplomatic message causing everyone except Keith revert to child-like behavior.

Keith finds and shelters Shiroe, who is fleeing from a psychic exam. Shiroe is arrested while in Keith's care, but manages to stir doubts in Keith. The next day, much to Keith's surprise, everyone's memories of Shiroe and Jomy are erased. However, as Jomy attempts to communicate yet again, Shiroe flees the station and is shot down by Keith.

Eight years after Shiroe is killed by Keith, the Mu are still drifting through space in search of Terra. Karina brings up the topic of natural childbirth in conversation with Jomy and her friends, and Jomy decides that this is the future path for the Mu. When the ship comes across an abandoned human outpost named Silvester 7 in the Silvester system, Jomy proposes to stay there, renaming the planet to Nazca. Meanwhile, Swena is investigating the existence of Moby Dick, the rumored space whale, as well as the events that took place on Station E-1077 eight years ago.
