Trafalgar begins his new life locked in his luxurious but empty quarters, acutely aware that the original owner of his body was driven to suicide by the relentless cruelty of the Morgain family. Rather than despairing, he activates his system status to discover his hidden SSS-grade Talent and the passive skill Sword Insight. Knowing he has to catch up on ten years of missed training, he spends hours in deep meditation, successfully igniting his Origin Core in less than an hour—a feat that normally takes years of agonizing effort. This quiet breakthrough marks the turning point of his existence, but the real test comes when he is summoned to a family banquet presided over by his tyrannical father, Valttair, and surrounded by hostile stepmothers and siblings. The family dinner is a gauntlet of verbal abuse, with his sadistic sister Rivena and half-siblings mocking his talentless past, only for Trafalgar to shock the entire table by revealing his rapid Core awakening. Before they can fully process this impossible reversal, a sudden demon invasion interrupts the feast, and Valttair coldbloodedly orders Trafalgar to the front lines to prove his worth. Thrust into a chaotic battlefield, Trafalgar relies on his Sword Insight to copy elite movements, dodging lethal strikes and slaying monsters with a basic iron blade. The danger peaks when a rogue Morgain soldier, secretly sent by Rivena to assassinate him under the guise of an accident, lunges for his throat. Trafalgar intercepts the blade, drives his sword through the traitor's heart, and witnesses his father effortlessly cleave a thirty-meter colossus in half with a single divine strike. Exhausted and blood-soaked, Trafalgar realizes his survival has painted an even larger target on his back. As he recovers from the battle, he must confront the terrifying reality that his own blood relatives will stop at nothing to see him dead, and his next steps will determine whether he becomes a legendary tyrant or just another forgotten corpse in the snow.

After surviving the battlefield, Trafalgar returns to the castle and establishes his dominance by severing the hand of a disrespectful soldier who harassed his loyal maid, Mayla. This display of ruthlessness earns him a trip to the family treasury, where he bypasses legendary weapons to choose a dusty, evolutive sword named Maledicta. His training intensifies under his sister Lysandra, who teaches him the legendary Morgain Blade style, which he copies instantly using his Sword Insight. Soon, he is sent on a high-stakes mission to inspect a disputed mana crystal mine on the border of the demon Zar'khael territory. Alongside his childhood friend Zafira and her powerful father Malakar, Trafalgar enters the depths of the mine, only for a sudden rift to tear open, unleashing grotesque Void Creatures. The ground collapses beneath them, plunging Trafalgar into a bottomless dark abyss. As he falls, his system flares with a world-shaking notification: his dormant bloodline has awakened, revealing his identity as a half-primordial being. He crashes into the cavern floor but survives thanks to his newly unlocked Primordial Body, which triples his mana absorption and enhances his physical stats. Alone in the dark, surrounded by the corpses of his companions, Trafalgar must fight his way through hordes of crystal-backed crabs and a massive, eight-meter-long venomous serpent. In a desperate struggle, the serpent swallows him whole, but Trafalgar ignites Maledicta with the beast's own acidic venom, unleashing a devastating Arc Slash that detonates the creature from the inside out. Covered in black blood and slime, he stands victorious but trapped in the deepest depths of the earth, realizing that his survival depends on climbing a sheer cliff face with no food or water. As he prepares to scale the impossible wall, he hears a strange, rhythmic scratching echoing from the pitch-black tunnels ahead, signaling that he is not the only predator lurking in these forgotten depths.

Trafalgar successfully scales the cavern walls and returns to the surface, where his survival stuns both his family and the demon lords. His progression is verified when his Core breaks through to the Spark rank, forcing his father Valttair to acknowledge his worth. At the Grand Council of the Eight Great Families, held on a magnificent floating island above the clouds, Trafalgar attempts to maintain a low profile while enjoying the lavish banquet. However, his peaceful evening is shattered when the arrogant noble Alfons au Vaelion publicly insults him and his demon friend Zafira, throwing down a glove to challenge him to a duel. Valttair and Alfons's father wager a legendary-grade item on the outcome, and Alfons arrogantly limits his own power to match Trafalgar's Spark rank. The duel takes place in an obsidian chamber before the gathered high nobility, where Alfons unleashes a barrage of elemental spells. Trafalgar effortlessly dodges the fire, water, and stone attacks, utilizing his copied Morgain Blade style to dismantle Alfons's defenses with cold, surgical precision. He shatters Alfons's magical barrier and delivers a series of physical strikes that humiliate the arrogant noble, ending the fight with a crescent wave of force at his throat. This stunning victory earns Trafalgar the legendary ring Oathbinder and forces the entire nobility to reassess the trash heir of House Morgain. But the triumph is short-lived: as Trafalgar steps onto a quiet balcony to catch his breath, a mysterious woman in a black veil paralyzes his body with powerful magic and forces a strange crimson pill down his throat. He collapses onto the cold marble as his bloodline violently reacts to the mysterious substance, leaving him unconscious and vulnerable to a web of ancient conspiracies. When he finally opens his eyes, he is greeted by a blindfolded girl with scars across her eyes, leaving him to wonder if he has found a new ally or a deadly executioner.

Following the Council, Valttair punishes Trafalgar's secrecy by sending him to the prestigious Velkaris Academy alongside Lysandra. Before his departure, Trafalgar uncovers a plot by his stepmother, Seraphine, who has erased his maid Mayla's memories and hired mercenaries to assassinate him during his journey. Trafalgar travels through Euclid, where his uncle Mordrek teaches him the Severance Step evasion technique, and he crosses paths with a dragon lord named Caelvyrn. Upon arriving at the massive metropolis of Velkaris, Trafalgar registers at the academy and immediately begins building his personal faction, rescuing a beastgirl named Garrika and dealing with a corrupt businessman named Lucien. The academy's entrance exam thrusts him into a sprawling stone labyrinth filled with monsters and rival students, where everything is permitted. Trafalgar navigates the maze, relying on his Primordial Body to absorb massive amounts of ambient mana and heal his fatigue. The trial escalates when a dark rift tears open, unleashing Void Creatures that threaten to slaughter the examinees. Trafalgar is forced to team up with Cynthia, a high-level archer whose power dwarfs his own, to face an Infernal Warden that pushes his Spark Core to its absolute limit. They manage to defeat the beast, but the battle leaves Trafalgar physically drained and mentally exhausted, realizing the vast power gap between himself and the academy's elite. As the trial's final hours tick away, the shadow of the veiled woman looms over his thoughts, and he senses that the rifts are actively targeting him, turning the academy exam into a desperate fight for survival against forces that transcend the physical realm. With the labyrinth walls shifting around him and rival students closing in to eliminate the weakened Morgain heir, Trafalgar must push past his limits once more, knowing that a single misstep will lead to his permanent deletion from this world. He grips Maledicta tightly, bracing for the final wave of enemies as the dark corridors begin to collapse.
