Two thousand years ago, the Demon King Arkanis Voidborn ruled the world with unmatched power, uniting demons, beasts, and even humans under his fearsome but just reign. His era ended with betrayal, sealing, and the erasure of his legacy from history.
Now, Arkanis has reincarnated in the modern era as a human-demon hybrid infant, retaining all memories and powers of his past life. The Demon Kingdom has modernized, and magical schools train the descendants of past heroes, villains, and royals. Arkanis enrolls in The Demon Legacy Academy, a prestigious school for young demon nobles, descendants of heroes who once fought him, and prodigies of magic.
The twist? Everyone underestimates him, believing the "true Demon King" was long gone. And now, he's back, determined to reclaim his legacy, challenge false histories, and reveal the truth about his immense power… all while attending school with his descendants.
Chapter 1 – Rebirth of the Demon King
The storm tore across the night sky, lightning fracturing the clouds like shards of broken crystal. Amidst the chaos, a single infant cried though it was no ordinary cry. The sound resonated with an unearthly depth, shaking the walls of the small cottage nestled in the outskirts of the Demon Kingdom's capital.
The child, swaddled in plain cloth, opened his eyes, revealing irises swirling with colors no human had ever seen. Within them danced the memories of a thousand battles, the faces of generals and kings, the screams of countless defeated enemies, and the quiet, unyielding weight of destiny itself.
"This… this is impossible," whispered the midwife, stepping back, her face pale. "Such power… in a newborn?"
The infant Arkanis Voidborn, reborn gazed at her with a look far older than sixteen years, far older than the world itself. His tiny fist clenched, and the flames from the hearth warped as if alive, bending to his will. A single flick of his hand caused the room to tremble. A vase shattered, yet the shards floated, hovering midair as if caught in invisible threads, before settling gently back on the floor.
From the shadows, a cloaked figure watched silently. Professor Zephyros, one of the few who remembered the old Demon King's era, nodded. "He has returned," the old man murmured, voice heavy with awe. "The world will not recognize him… not yet. But they will."
Two years passed like a fleeting shadow. While other children played with toys or learned to speak their first words, Arkanis absorbed everything around him effortlessly. Languages, magic, combat techniques no knowledge was beyond his reach. By the age of three, he could summon firestorms with a thought, manipulate shadows as if they were extensions of his own limbs, and bend metal with a gesture.
Yet he did not flaunt his power. Not yet. He waited, as the world had once underestimated him and it had nearly destroyed him.
By the time Arkanis was sixteen, he was ready. Cloaked in the guise of an ordinary student, he approached the gates of the Demon Legacy Academy, the most prestigious magical institution in the kingdom. Those gates had seen the descendants of heroes and villains alike, all trained to surpass their ancestors. But none would surpass him not truly.
The guards, clad in enchanted armor, raised their eyebrows at the unusually calm boy. "Name?" one asked, voice tinged with suspicion.
"Arkanis Voidborn," he replied simply. The sound of his name carried a weight that made even the seasoned guard shiver, though he could not explain why.
The entrance examination was legendary, a test said to separate prodigies from legends. Students from noble families and famous bloodlines had failed for generations. But Arkanis? He stepped into the arena, surrounded by an aura that warped the very air. Flames danced without heat, shadows twisted unnaturally, and the earth beneath his feet seemed to pulse in recognition of his presence.
When the first challenge appeared a towering construct of stone and elemental energy other students gasped. It was meant to be nearly invincible, designed to break even the most skilled young magicians.
Arkanis blinked once. And in that instant, the construct shattered, collapsing into dust as though it had never existed.
A silence fell over the arena. Whispers spread like wildfire: "Who… who is this?"
Arkanis bowed politely to the examiners, a faint smile on his lips. "I am… here to reclaim what was once mine."
And though the world did not yet remember, the Demon King had returned.
