14,000 light-years from the Earth located in a stellar system within the Scorpio Cluster lies the planet of Boazan. Its local populace and natural environment are almost identical to that of the Earth's albeit the former benefits from scientific innovations and technological developments which are far more advanced than what humanity has ever achieved. The entire planet is wholly governed by an oligopolistic monarchy with a cruel caste system: Boazanians born with horns are highly regarded and bestowed with elite privileges while the hornless are branded as slaves and are forced to work on the most physically demanding tasks under constant threat of pain, confinement, and death. Tension between the classes reached its zenith when Boazan's highly-revered Chief Science Minister La Gour was exposed as a hornless pretender mere moments before his ascension to the throne; an exploitative revelation perpetrated by the former's ambitious bastard cousin Zu Zambajil who wanted the empire for himself. Freed from incarceration by a band of hornless dissidents, La Gour subsequently led a daring insurrection against the empire but their valiant efforts were easily thwarted by Boazan's vastly superior military. Using the rebels' last remaining space saucer, La Gour fled to faraway planet Earth. Assimilated into human society, La Gour started a family with a local woman while further developing his scientific expertise under a new persona: "Professor Kentaro Go".
