Free Underbar, deputy captain of Dorothea’s Unit 1, enforces laws against illegal fairy exploitation. His sharp blue eyes, short dark brown hair, and faint beard frame a stern expression softened by traces of empathy. A Unification War veteran bearing a fairy organ transplant, he channels the wolf-like fairy Red Hood, whose superhuman strength, sonic howls, and heightened senses come at a cost: injuries to Red Hood wound him in turn. Once a soldier from Ledrad, he fought beside Wolfran Row before joining Dorothea, later infiltrating the Gui Carlin mafia to recruit Marlya Noel—a rare natural fairy host—sparing her arrest to forge an alliance against postwar threats.

Their investigations target rogue fairy soldiers, unstable artifacts like the Black Fairy Tome, and former comrades turned enemies. Free’s missions pit him against Wolfran, now a foe wielding personal history as a weapon, and adversaries like Beevee Liscar, whose dominance shattered him even with the fairy-armament Fratanil. He fights with paired blades and Red Hood’s savagery, yet hesitates to deliver fatal blows to Wolfran, exposing unhealed fractures from their shared past.

A strategist who coordinates with allies like Klara Kysenaria and Serge Tovah, Free conceals Marlya’s unique condition while steering operations to quell rebellions, safeguard targets like Ray Dawn, and dismantle plots by figures like Schwarz Diese. His leadership blends wartime pragmatism with unexpected compassion, urging Marlya to view sacrifice as collective resilience rather than individual weakness.

Behind his tactical mind lies a shell-shocked veteran navigating political webs: delivering intelligence to Ledrad’s prime minister, negotiating with informants like Bitter Sweet, and balancing duty against the moral toll of enforcing order. Lingering loyalty to old bonds and the scars of loss anchor his resolve to stabilize a fractured world, one where fairy organs and lingering war wounds blur the line between justice and survival.
