Description
Burckhardt is a supporting character in the anime, introduced as a noble knight who serves under Juliana, a key leader within the Holy Capital. He is a seasoned warrior and a member of the Volunteer Army, the assembled force fighting against the Black King and his corrupting miasma.

His personality is initially defined by a rigid, traditional sense of pride and loyalty, particularly towards his commander, Juliana. Burckhardt holds a deep-seated contempt for the protagonist Aram due to the young man's unusual and unconventional ability to steal mana from others. This disdain is not simply a matter of tactical disapproval but stems from a more profound personal conflict. His strained relationship with Aram is further complicated by Burckhardt's own unresolved personal "baggage," which creates unforeseen problems and fuels his animosity, particularly when Aram receives recognition or gifts that he feels are unearned.

Burckhardt's primary role in the narrative is as an initial antagonist to Aram within the Volunteer Army, embodying the suspicion and rejection the hero faces from those who adhere to traditional combat ethics. He is fiercely protective of Juliana and follows her orders faithfully. When Juliana decides to leave for the Holy Capital, she specifically asks Burckhardt to remain behind and support Aram, a command that puts him in direct conflict with his own feelings of resentment. This internal conflict sets the stage for his tragic downfall.

Unable to reconcile his duty with his resentment, Burckhardt becomes susceptible to the corrupting influence of "obscurose," a dark miasma spread by the Black Army that preys on negative emotions. This corruption transforms him into a demon, turning him against his former allies. His development is therefore a cautionary arc about how pride and an inability to adapt can lead to self-destruction, as he goes from a respected knight to a corrupted monster.

Despite his transformation, Burckhardt resurfaces later in the story. In his corrupted state, he attacks the arche during a critical expedition to invade the Black King's palace, creating significant obstacles for the heroes even after his fall from grace. His actions demonstrate the persistent threat of the Black King's corruption, showing how even the most loyal individuals can be weaponized against their own cause.

As a knight, Burckhardt is a formidable combatant, skilled with a sword and in conventional physical combat. His abilities do not include magic, which further fuels his disdain for Aram's unconventional mana-based techniques. His notable abilities as a fighter are ultimately subverted when he is transformed into a demon, gaining dark powers but losing his humanity and free will in the process.
