Kazuma Nobi never asked for a second chance. After dying in the most humiliating way imaginable—crushed and discarded like trash—he awoke in the body of Xenos Zentharix: a half-demon runt with no past, no family, and a reputation worth less than dirt.
But something stirred within him. Something ancient. Something divine.
Sealed inside Xenos’s body is none other than Lucifer—the first sinner, the fallen king, betrayed by Heaven and hunted by gods. His power? Muted. His pride? Intact. And now, his soul shares a body with a cynical human who’s done taking orders from life or fate.
When Xenos is forcefully enrolled in the prestigious yet rotting Demon King Academy—a place built on hollow bloodlines and borrowed power—his very presence shatters the balance. Spells fail. Artefacts break. Elders kneel. He’s not a prodigy. He’s a problem.
While Lucifer whispers of vengeance and cosmic reckoning, Kazuma carves his own path—calm, calculated, and terrifying in his resolve. Together, they challenge the system, bend ancient laws, and drag buried truths into the light.
He’s not here to prove himself.
He’s here to rewrite the script they buried him under.
And this time, even gods will know fear
