Ulfran Low is a former Fairy Soldier who fought in the great war beside Free Underbar. The conflict took the lives of his wife and child, an unbearable personal tragedy that plunged him into a deep depression and severed his faith in the world. This loss became the sole engine of his existence, driving him to a life of vengeful terrorism in the war's aftermath.

As a terrorist, Ulfran operates with cold pragmatism and a typical absence of emotion. Yet a smoldering fire ignites within him at the mention of the war or the onset of combat. Every action is fueled by deep-seated pain and anger, and he is known to burn with fervor in a fight, especially when facing former comrades or those linked to the conflict.

Ulfran is accompanied by a fairy named Fitcher, whose features resemble bark and twisted wood. Fitcher is equipped with six arms that terminate in sharp blades, which it uses to slice apart enemies.

His operations repeatedly bring him into confrontation with the organization Dorothea and his old ally Free Underbar, setting him directly against his former comrade. His campaign of terror contributes to the widespread instability and illegal fairy activity that troubles the nation-state following the war.
