Description
Bercouli Herlentz, also known as Bercouli Synthesis One, began his life as a human swordsman and co-founder of Rulid Village before ascending as the oldest Integrity Knight. His physique bears the marks of decades of combat—muscular, iron-gray hair streaked with blue, and battle-earned scars. Though biologically in his forties, his mind spans three centuries due to temporal manipulation by Axiom Church’s Administrator Quinella, who reshaped him into the first Integrity Knight through memory suppression and synthesis rituals.
Once a rebel opposing the Church, Bercouli’s capture bound him to Quinella’s regime. For centuries, he commanded the Integrity Knights in defense of the Human Empire against the Dark Territory, honing unparalleled combat expertise. His Time Piercing Sword manipulates temporal forces, enabling strikes across past or future trajectories. Techniques such as "Kara-Giri" (Void Slash) and "Ura-Giri" (Reverse Slash) pierce conventional defenses by targeting moments in time, demanding meticulous precision.
Balancing self-assured pragmatism with a laid-back demeanor, Bercouli retains critical awareness of the Church’s control despite altered memories. He values stability over blind allegiance, mentoring Fanatio Synthesis Two and fostering a paternal bond with Alice Zuberg, whom he nicknames "little miss Alice." A tactical leader, he approaches battles with calm scrutiny, often probing opponents through dialogue to gauge their resolve.
His arc pivots during a climactic duel against Eugeo in the Central Cathedral’s bathhouse. Overconfidence nearly proves fatal as Eugeo wields the Blue Rose Sword’s life-draining power and environmental tactics, triggering Bercouli’s fragmented recollections of founding Rulid and his human past.
In the final conflict against Dark Territory forces, Bercouli faces the superaccount Vecta (Gabriel Miller). Despite catastrophic injuries and losing an arm, he executes "Ura-Giri" to strike Vecta’s past self, sacrificing himself to secure victory. His demise culminates in a spectral farewell with a memory-projected Quinella, resolving their tumultuous legacy. Posthumous revelations confirm he fathered a child with Fanatio, extending his impact on the Human Empire.
Beyond core events, Bercouli features in spin-offs like *Sword Art Online: Alicization Lycoris*, showcasing rare humor alongside his stoic presence. His innate time perception and crisis leadership cement his legend within Underworld’s chronicles.
