In a future where humanity is constantly under attack by the invasive alien race known as the Novas, young individuals are equipped with stigmata that grant them extraordinary powers. These empowered fighters, consisting of female Pandoras and male Limiters, are trained at military academies to combat the relentless attacks, called Nova Clashes. Kazuya Aoi begins his journey at the West Genetics military academy on a day marked by a Pandora competition. During this event, Kazuya mistakenly believes that Satellizer el Bridget, a powerful Pandora nicknamed the "Untouchable Queen," is his late sister and impulsively hugs her. Despite costing her the contest, Satellizer notices that Kazuya's touch doesn't repel her, leading her to choose him as her Limiter. As they forge a partnership, they must navigate the challenges posed by their seniors and the ever-present danger of the Novas.

In this installment

After the tenth NOVA battle, the Chevalier determines that NOVA attacks are increasing and that their loss of Pandora soldiers is faster than they can produce new ones. In response, they initiate the E-Pandora Project, designed to convert ordinary people into Pandoras. Representatives from Pandoras around the world, including Satellizer, Kazuya, and Rana, are summoned to the Alaskan base to witness this new initiative. But as the project moves forward, suspicions grow, and the gathered Pandoras become more unsettled about its hidden objectives.
