Hargent, known as Hargent the Silencer, serves as the sixth general of the New Principality of Aureatia. Physically, he is an adult male characterized by black hair cut to ear length and blue eyes, and he is often depicted wearing a cape and boots, with a distinct mustache and a sword at his side.

As a high-ranking military leader, Hargent's personality is defined by a strong sense of pride and personal honor in combat. This is demonstrated during an encounter with the dragon Vikeon, where he refuses outside assistance, insisting on handling the battle himself to preserve his own dignity and that of his search party. His role in the story primarily unfolds as he leads a mission to locate the dragon Vikeon for Aureatia, a task that brings him into direct conflict with the powerful wyvern, Alus the Star Runner.

Hargent has a strained and notable history with Alus, a mutant wyvern who is also a labyrinth explorer. Their relationship is adversarial, defined by a past conflict that has made them rivals. This dynamic is central to their interaction when they meet during the hunt for Vikeon. Despite their enmity, Hargent acknowledges Alus's strength; after Alus ultimately slays the dragon, Hargent suggests he should become a contender in the search for a hero, though he qualifies this by stating he would never rely on Alus's power for his own victory due to his pride.

In terms of abilities, Hargent is a capable fighter equipped for ranged combat, wielding a massive crossbow as his primary weapon. However, his skills are shown to be insufficient against a fully powered Vikeon, as his projectile fails to damage the dragon. His development across the encounter shows a transition from a general determined to face a powerful foe alone to a pragmatic leader who, despite his personal feelings, recognizes the potential value of a powerful ally like Alus, even if he refuses to directly benefit from that power himself.
