Agyle holds the position of Red Demon General, one of the Four Demon Generals serving the Goblin Society. His core duty involves carrying out King Deros's orders to capture the ancient treasure Quaschika, crucial to the Goblins' goal of reclaiming the Earth's surface.

He is consistently portrayed as less competent and more hapless than his fellow generals. This depiction aligns him thematically with Ryo Rando of the opposing Rando family, as both characters primarily serve as sources of comic relief. Agyle's plans and combat endeavors routinely result in failure or unintended consequences, cementing his role as an emblem of ineptitude within the Goblin ranks.

While other generals receive minimal but distinct character moments—such as Bluzon's nobility or Groizy's ambitions—Agyle lacks comparable focus or development. His appearances increase in frequency, particularly in later episodes, but this does not lead to deeper exploration of his motivations, background, or personal evolution. He remains defined by his failures and his status as a secondary antagonist.

No details emerge regarding Agyle's origins, his history before joining the Goblin Society, or any significant changes to his role or personality across the series' 24 episodes. Similarly, no official expanded media featuring the character or detailing his story further are documented. His narrative arc concludes without resolution or substantive progression beyond his established role.
