Nie Given leads a resistance faction against Drake Luft's military conquests. Drake's forces killed both his parents early in the conflict, leaving Nie the sole heir and last survivor of the Given family name; this loss fuels his embittered resistance dedication. He commands his father's Aura ship, the Zelana, enforcing a harsh but committed leadership style over his crew.

His personal life involves complex romantic entanglements. Nie maintains a secret relationship with Riml Luft, Drake's daughter, who defects to aid his resistance. This creates a star-crossed dynamic, as Riml faces distrust from Nie's allies despite proving her loyalty in battle. Concurrently, fellow resistance member Keen Kiss, daughter of a noble house, harbors unrequited feelings for him. Nie remains largely oblivious, focusing primarily on Riml.

Throughout the war, Nie evolves from a revenge-driven leader bound by rigid honor into a more seasoned commander, though he still displays moments of intense emotional decision-making—physically disciplining Riml during conflicts or refusing retreats on principle. A significant turning point occurs when Keen is killed by Muisy, a prisoner accidentally freed during the resistance's assault on Drake's flagship, the Will Wipps; her death compounds his losses.

The destruction of the Zelana, his father's last legacy, during the final battle devastates him. This loss, combined with Riml's murder by his mother Luuza, pushes him into a reckless, death-seeking state. In a final act of vengeance, Nie guns down Luuza and launches a solitary, suicidal charge against Drake aboard the Will Wipps, culminating in his death.

No substantial information exists regarding his portrayal in subsequent OVAs like *The Tale of Neo Byston Well* or other Byston Well-related media.
