"Dragon Eye" is a manga series set in a world plagued by a mysterious and deadly virus known as the Miasma. The virus transforms humans into monstrous creatures called Infectants, which spread chaos and destruction. To combat this threat, the International Disease Control Organization (IDCO) establishes the Special Disaster Response Team (SDRT), composed of individuals with unique abilities derived from the Miasma itself. These individuals, known as Dragonists, wield powers tied to the mythical dragons and are humanity's last line of defense.

The protagonist, Leila Mikami, is a young and determined Dragonist who joins the SDRT to fight the Infectants and uncover the truth behind the Miasma. Leila possesses the power of the Azure Dragon, granting her enhanced strength and combat abilities. Her journey intertwines with that of Issa, a former soldier and fellow Dragonist who wields the power of the Vermilion Bird. Together, they navigate the dangers of their world while grappling with their own personal struggles and the moral complexities of their mission.

As the story progresses, the SDRT faces increasingly powerful Infectants and uncovers deeper layers of conspiracy surrounding the origins of the Miasma. The narrative explores themes of survival, sacrifice, and the blurred lines between humanity and monstrosity. Key characters include Ruruka, a skilled Dragonist with the power of the White Tiger, and Shiki, a mysterious figure with ties to the Miasma's origins. The series balances intense action sequences with moments of introspection, delving into the emotional and psychological toll of living in a world on the brink of collapse.

The plot builds toward a climactic confrontation with the true source of the Miasma, revealing its connection to ancient dragons and the fragile balance between destruction and rebirth. Through its exploration of the characters' relationships and the evolving threat of the Miasma, "Dragon Eye" presents a compelling narrative that combines elements of fantasy, science fiction, and post-apocalyptic storytelling.
