When Leon opened his eyes again, he wasn't Leon anymore.
He was lying in a grand bedroom of black marble and silver drapes, surrounded by anxious maids and weeping servants. His new body—small, fragile, six years old—ached with grief not his own.
The memories came like a storm.
The Valvas Clan.
The screams of his parents.
The fire that devoured their mansion.
Alex Valvas and Jessica Valvas—noble devils, the Lord and Lady of the Valvas Clan—were dead. Murdered by the Naberius Clan of the Old Satan Faction. Their son, Roy Valvas, was the only survivor.
And within Roy's heart, Leon's soul awakened.
The Valvas Legacy
The Valvas Clan, ranked 11th among the 72 Pillars, were renowned across the Underworld for their mastery of swordsmanship and their unique affinity for every element: fire, water, wind, earth, lightning, light, and darkness.
Their lineage was noble—Granddukes of the Devil World.
Roy's grandfather, Darius Valvas, once known as the Valvas Sword Saint, was a legend whose blade was feared by devils, angels, and fallen alike. Even now, his presence commanded awe.
His wife, Clara Valvas, daughter of Zekram Bael, was a woman of unshakable will and grace—a true matriarch of noble blood.
Their household was vast and filled with allies from the Agares, Bael, Sitri, Astaroth, Phenex, and Gremory clans. Even Grayfia Lucifuge, the silver-haired maid once saved by Darius and Clara during the civil war, served them with devotion—treating the Valvas family as her own.
The Awakening
Roy—no, Leon—felt a surge in his head.
A mechanical chime rang within his mind.
[System Activated.]
[User: Leon Crome → Roy Valvas recognized.]
[Welcome to the World of High School DxD.]
[Initial gift: 100,000 System Points.]
He froze.
"So... I've been reborn... into this world."
Through the pain of loss, his reborn soul found purpose. He would live again—not as Leon Crome, the forgotten soldier—but as Roy Valvas, heir of the Granddukes.
He would rebuild his house.
He would avenge his parents.
And he would become stronger than anyone in this world—devil, angel, or god.
The Bonds Around Him
Even amidst tragedy, light remained.
Seekvaira Agares, his childhood friend and cousin through his mother, wept at his side, her usual composure broken.
Sona Sitri, the serious girl with sharp eyes, promised to help him train when he recovered.
Latia Astaroth and Iryuka Glasya-Labolas sent letters filled with warmth and worry.
Even Serafall Leviathan herself, Sona's elder sister, visited often—bringing smiles and snow wherever she went.
And Grayfia... his family's ever-loyal maid, who had watched him since birth, held him tightly every night he woke from nightmares. To her, he wasn't just a young master. He was family—perhaps something even more.
A New Path
Years would pass before the Underworld would once again whisper the name Valvas.
But on that night, in the ruins of his family's hall, the rebirth of a legend began.
"I swear... I'll make the Valvas name shine brighter than ever."
[Quest Accepted: Rebuild the House of Valvas.]
The System glowed softly.
Roy Valvas smiled through the tears.
The devil world didn't know it yet—but a storm had been born.
