After Earth's demise transformed it into Terra, a space society thrives on logic under the reign of supercomputers. In this world, children are born in artificial wombs and assigned random parents, with an 'Adulthood Exam' at age 14. The looming threat to humanity is the Mu—espers who challenge the norm. Jomy Marquis Shin, facing his Exam, discovers a sinister plan to wipe his memories. Saved by Soldier Blue, a Mu leader, Jomy learns of his own esper heritage and impending death sentence. As Soldier Blue passes his legacy to Jomy, the choice arises: lead the Mu in secrecy or wage war for their return to Terra.
