BRIGADOON: Marin to Melan

A 13-year-old orphan named Marin Asagi lives in a 1970s alternate Tokyo when an unknown mechanical force overtakes the sky, releasing a Monomakia—a weaponized entity programmed to kill her. Her only hope is Melan Blue, a Gun-Swordsman with weaponized limbs, flight, and retractable armor, who is tasked with her protection. Marin and Melan journey between two worlds in search of answers to pressing questions: who is responsible for the Monomakia, why Marin is targeted, who assigned Melan to guard her, and what lies behind the mystery of Brigadoon.
