Beevee Liscar, a legendary fairy soldier, fought relentlessly until the War of Unification's conclusion. Post-war, he transformed into an agent of war and leader of a mercenary band. He ranks among the elite Seven Knights, famed for their combat prowess during the conflict.

His combat capabilities feature superhuman physical characteristics and masterful swordsmanship. He wields the fairy Aizencup, which bestows further superhuman physical traits and Type 1 immortality. Aizencup can inflict massive structural damage, including demolishing walls. Beevee exhibits athletic human movement speed paired with supersonic reaction and combat speed, allowing him to counter threats like rifle bullets. His Wall level striking strength and durability enable him to kill artificial fairies, penetrate their metal shields, and endure attacks from foes like Free Underbar. Aizencup operates effectively within tens of meters. A critical vulnerability exists: any damage sustained by Aizencup transfers directly to Beevee.

Within the narrative, Beevee serves Duke Diese as a key antagonist. He spearheads assaults against the agency Dorothea, including a major raid on a train transporting a fairy weapon where he eliminates agent Oz Mare. His actions heighten political tensions, contributing to Duke Diese's declaration of independence from the Unified Zesskia Empire. Alongside Wolfran Row, Beevee employs artificial fairies to invade the capital Rondacia, directly challenging governmental authority and igniting widespread conflict. His calm demeanor in combat, notably whistling amidst active battlefields, underscores his confidence and formidable presence.

Specifics regarding his early background, age, or ultimate fate remain less documented, while his depicted role consistently shows him as a persistent instigator of military action against the postwar order.
