Highschool DxD: Curse Devil
Born into the prestigious Gremory clan, Alexander should have been destined for greatness. As the son of Sirzechs Lucifer and Grayfia Lucifuge, expectations were high, yet from the moment of his birth, he was deemed a disappointment. Unlike his father, his grandmother, or even his younger aunt, Rias, he lacked the defining trait of their bloodline—the overwhelming Power of Destruction.
Where Rias was cherished, nurtured, and celebrated, Alexander was forgotten. His parents turned distant. His father, the most powerful devil of his generation, saw no potential in him. His mother, the ever-dutiful maid of Lucifer, followed suit. The nobles of the Underworld, the servants of the household, and even his supposed peers—all cast him aside, their eyes set on Rias, the true heir.
For years, he lived in the shadow of his family, unnoticed and unacknowledged. But the world had made a mistake—they forgot that even in the darkness, a spark can ignite into an unrelenting fire.
Now, as whispers of his rise begin to spread, the devils who once ignored him start to look his way. Too late. The forsaken heir is no longer waiting for their approval.
