The OVA focuses on the aftermath of the Janus crew's return to Earth and their efforts to rebuild their lives while facing new challenges.

The narrative centers on Kate, one of the original Janus crew members, who has been separated from the group and is living a quiet life on Earth. However, her peaceful existence is disrupted when she is kidnapped by a group of rogue Zolans who seek to use her as leverage in their ongoing conflict with humanity. The Janus crew, now reunited, must embark on a daring rescue mission to save Kate and prevent the Zolans from gaining an upper hand in the war.

The plot explores themes of resilience, camaraderie, and the lingering effects of war, as the Janus crew confronts their past traumas while striving to protect their future. The OVA delves into the emotional struggles of the characters, particularly Kate, who must grapple with her memories of loss and her desire for a normal life. The rescue mission is fraught with tension and danger, as the crew faces not only the Zolans but also internal conflicts and moral dilemmas.

Key characters include Kate, whose resilience and determination drive much of the narrative, and the other members of the Janus crew, each of whom brings unique skills and perspectives to the mission. The Zolans, while portrayed as antagonists, are given depth through their motivations and the complexities of their relationship with humanity. The OVA maintains a balance between action and introspection, providing a compelling continuation of the "Ginga Hyōryū Vifam" saga.
