Beevee Liscar, a former colonel and elite member of the Seven Knights in the War of Unification, wielded the potent fairy weapon Eizenkopf. This power cemented his formidable combat reputation. Post-war, he shed his uniform to command a criminal gang, collaborating with Wolfran Row to secure illegal artificial fairies for his ambitions.

Liscar orchestrated a deadly train ambush, eliminating Dorothea operative Oz Mare during a fairy weapon interception. This act typified his strategy to disrupt the postwar peace. He later masterminded a major assault on the Unified Zesskia Empire, launching a diversionary rebellion in Schwarz Diese's barony to draw imperial forces away. While Dorothea Director Nein Auler countered this feint, Liscar spearheaded the primary attack on the Imperial Palace.

Advancing under direct rifle fire, Liscar used his fairy weapon to shatter the heavily fortified Heavenly Gate. His tactics displayed both martial skill and psychological warfare, marked by conspicuous whistling during combat. He clashed with Free Underbar and Marlya Noel during the infiltration but was ultimately defeated by Nein Auler in Rondacia. Captured, he faced imprisonment for rebellion and terrorism.

His actions aimed to overthrow the political order, fueled by wartime grievances and alliances like Wolfran Row's, challenging Emperor Harol and Prime Minister Golbarn Helwise. His arc concluded with the insurrection's failure and the restoration of imperial control.
