Hajime Amamori, a junior high student, navigates a life marked by tragedy and transformative purpose. Orphaned when his parents perished in a spacecraft-related explosion, he initially channels grief into pursuing the Millennial Thieves, blaming them for their deaths. His quest for vengeance unravels upon discovering Selen, the Thieves’ leader, had risked her life to rescue his parents during an assault by La Metal loyalists. This revelation redirects his focus toward averting broader conflicts. Under the care of his astronomer uncle at Tsukuba Observatory, Hajime cultivates a fascination with the cosmos and bonds with Yayoi Yukino, his uncle’s assistant. Their connection strengthens as he uncovers her secret role as the Millennial Queen, a key figure in La Metal’s schemes. Though shaken by her extraterrestrial origins, he allies with her to safeguard Earth, prioritizing empathy over division. Critical injuries from a clash with La Metal forces lead to cybernetic enhancements engineered by Yayoi and her allies, amplifying his intellect, reflexes, and innate piloting skills. These upgrades allow him to master advanced spacecraft effortlessly. In a cinematic iteration, he commandeers a salvaged WWII Zero fighter from a museum exhibit, repurposing its antiquated frame to repel La Metal’s invasion with daring ingenuity. Facing apocalyptic scenarios—like traversing a meteor-ravaged Tokyo to rescue Yayoi amid crumbling infrastructure—Hajime evolves from impulsive grief to calculated leadership. He collaborates with allies to retrofit historical military technology, transforming relics into weapons against alien incursions. His arc culminates in confronting Larela, La Metal’s ruler, where he rejects her tyranny and brokers a fragile peace between Earth and her empire. This diplomatic pivot underscores his growth from traumatized orphan to bridge-builder, championing coexistence over conquest. Subtle threads of admiration for Yayoi weave through his journey, though secondary to his cosmic mission. Similarly, his uneasy alliance with Selen, Yayoi’s sister, exemplifies his capacity to transcend distrust, cementing forgiveness as both personal creed and strategic necessity.
