Dagar, a royal technician of La Metalle, devotes his skills to Princesses Maetel and Emeraldas, crafting advanced armaments like Emeraldas’s laser lance and Maetel’s electromagnetic pulse pistol—tools pivotal to their fight against mechanization forces. As a father, he trains his son Jam in service to the crown, though their bond fractures when Jam’s mechanization drives him to betray the resistance. In a fatal clash, Dagar shields Maetel from his transformed son, his death cementing his allegiance to their cause.

His technical acumen unravels Hardgear’s schemes: analyzing mechanized subjects, he uncovers a control microchip within the queen’s capsule, exposing Hardgear’s manipulation of La Metalle’s populace. This revelation steels the sisters’ defiance.

Posthumously, Hardgear weaponizes Dagar’s mechanized corpse, turning his remains against Maetel and Emeraldas in a grim echo of his son’s betrayal. This macabre repurposing illustrates mechanization’s theft of autonomy and identity.

Dagar’s legacy endures through the armaments that empower the rebellion and the intelligence exposing Hardgear’s tyranny. His fractured kinship with Jam mirrors the era’s moral conflicts—weighing survival against loyalty, humanity against cold machinery.
