Legatee: The king must be pride

In the infernal realm of Hell, a shadow of discontent falls upon the throne of Pride, where Lucifer, the supreme ruler, reigns. His ambitious brother, Envy and known as Leviathan, plots a treacherous coup, fueled by corrosive jealousy and a burning desire for power. Leviathan orchestrates a brutal assault on Lucifer's family, aiming to extinguish the royal bloodline and seize the throne for himself. Amidst the carnage, only one survives: Xavier, Lucifer's youngest son.

As Lucifer teeters on the precipice of death, he makes a desperate plea to the Three Divine Natures - Justice, Love, and Trinity. Humbled by his love for his son and driven by a father's determination, he begs them to safeguard Xavier and raise him in secrecy, far from the clutches of Leviathan. Moved by Lucifer's sacrifice and the innocence of the child, the Divine Natures vow to protect Xavier.

Entrusting the infant to one of their most trusted allies, a fierce and skilled warrior, they task her with raising Xavier as her own. To shield him from the dangers of his true heritage, they subtly alter his memories, crafting a new past where he was rescued from a tragic fire by his devoted nanny. Xavier grows up in the human world, a realm brimming with latent magical abilities, blissfully unaware of his royal lineage and the extraordinary powers that lie dormant within him, waiting to be awakened.
