Overview:The collapse of the HOLY EMPIRE of the Milky Way that has lasted millennium results in a cosmic chaos in the Galaxy, plunging it into a long period of conflict among warring nations. This world of conflict is ideal for the men of ambitions. Among them is a young soldier in the army of the Kingdom of Gojo, THUNDER JET. During the war with the Kingdom of SAKURA, who alone resists Gojo's dominance in the Northern Territory of the Milky Way, Thunder Jet distinguishes himself by slaying SHUZEN, the King of Sakura, and the scene is witnessed by Simone, the daughter of Shuzen, who vows to avenger her father's death. Though he is handsomely rewarded, thunder Jet is not satisfied. He feels resentment toward DAN-JOE, the King of Gojo, for ordering him and his comrades in a suicidal attack that has caused the death of many of his friends. In order to get proper compensations for the families of his deceased comrades, Thunder Jet takes his case directly to the King, a defiant act that normally results in death. Indeed, he is sentenced to die, only to be rescued by Reila, the only daughter of Dan-Joe. She is touched by Thunder Jet's unselfish and courageous act. But that night, Boot City, the capital of Gojo, is stunned by a surprise attack. Hundreds of thousand soldiers descend on the City and catch Dan-Joe's army off guard.
