Marin is an ordinary junior‑high student who radiates cheerfulness and enjoys a caring adoptive household. Her routine shatters when an uncanny mirage arches across the entire sky. From a celestial formation named Brigadoon, lethal androids known as Monomakia pour down onto Earth and begin hunting the young Marin. While fleeing, she stumbles upon a blue vial inside a shrine; from it emerges Melan Blue, an alien who wields a sword‑mounted gun and vows protection. Together they must defend the planet while navigating family turmoil, school discrimination, and law‑enforcement scrutiny, ultimately uncovering Marin"s history and Melan"s mysterious purpose, all while learning to trust one another. The story unfolds in 1969 Japan amid a vibrant ensemble of allies and adversaries as they confront relentless danger and forge an unbreakable bond in the neon-lit night of Tokyo.
