Oliver Cardiff

Oliver is introduced as the brilliant front-line fighter and charismatic leader of Golden Dawn, commonly referred to as the “Hero Party.”

Despite his public image as a flawless hero, his personal history is deeply entangled with memory manipulation, lost promises, and the tragedy of his destroyed homeland.

As a child, he lost his hometown in an attack orchestrated by the Cyclamen Order, an event that should have defined his hatred and his bonds.

Instead, his memories and perceptions were forcibly rewritten, twisting his attitude toward the person who mattered most to him: Orun Dula.

Oliver was artificially created to be a regressive throwback to the original Hero, a manufactured “successor” meant to replicate a legendary bloodline.

However, when Orun Dula was born as a true natural throwback to that heroic lineage, Oliver was quietly reclassified as a mere “spare.”

Even after learning he was a backup to Orun’s talent, his friendship and loyalty to Orun did not waver in his original, unaltered self.

The two had once promised to save the world together as partners, standing side by side.

Ten years before the present timeline, however, recognition and memory alteration warped Oliver’s mind and emotions.

These changes gradually twisted his view of Orun, turning camaraderie into doubt, and doubt into rejection.

Later, the power of the King of Abilities releases him from this manipulation.

Freed from the altered recognition, Oliver regains all of his true memories, reverts to his original personality, and begins working secretly behind the scenes for Orun’s sake.

Oliver has yellowish-brown hair and gray eyes, giving him a sharp yet approachable look.

His build is slightly muscular, reflecting constant combat training and the lifestyle of a top-tier explorer.

His presence on the battlefield is both striking and reassuring to allies.

Combined with the aura of a “Hero” and “Sword Saint,” he embodies the classic image of a frontline champion.

In his true, unaltered self, Oliver is loyal, earnest, and deeply protective of those he cherishes.

Orun Dula, in particular, was not just a party member to him, but a true partner and best friend.

Even after discovering that he was artificially created and treated as a spare compared to the “genuine” Hero throwback Orun, his respect and affection for Orun did not crumble.

They had made a mutual promise to save the world together, a vow that defined Oliver’s sense of purpose.

However, after his memories and recognition were rewritten ten years earlier, his perception of Orun began to warp.

Small doubts about Orun’s strength and value slowly grew, not from logic or experience, but from that insidious manipulation.

Under this influence, the more he climbed in fame and difficulty, the more he started to question whether Orun truly belonged at his side.

These doubts were later reinforced by certain party members, pushing him toward a decision he never would have made in his right mind.

Once freed from the altered recognition by the King of Abilities, Oliver’s genuine core resurfaces.

He becomes driven by remorse and a renewed determination to support Orun from the shadows, using his position and strength to correct what was twisted.

Tragedy Ten Years Ago

When Oliver was nine years old, his hometown was attacked and destroyed by the Cyclamen Order, a fanatical religious cult.

This should have been the defining trauma of his childhood, shaping his relationships and his hatred toward those responsible.

Instead, after this tragedy, his memories and recognition were forcibly altered by an unknown agent or system.

Key emotional bonds, especially his bond with Orun, were distorted, and parts of his identity as a friend and partner were overwritten.

This manipulation did not erase Orun from his life.

Rather, it subtly but relentlessly twisted his feelings, making him increasingly critical and distrustful of the very person he should have treasured most.

Becoming an Explorer

Following the destruction of his homeland, Oliver became an explorer in Tsutrail, a major city known for its dungeons and adventurers.

There, he began to display the full potential of his innate abilities, rapidly rising through the ranks.

Thanks to his exceptional talent with the sword and his rare ability Mana Convergence, he soon stood out among his peers.

His prowess earned him a place as the ace of Golden Dawn, the Hero Party.

Within this party, he distinguished himself so dramatically that people began to call him the Sword Saint.

His reputation attracted attention both from allies and rivals, solidifying Golden Dawn’s status as one of the strongest S-Rank parties.

Oliver serves as the leader of Golden Dawn, the so-called Hero Party to which Orun Dula once belonged.

He is the central figure who coordinates the team, leads expeditions, and makes crucial strategic decisions.

In battle, his role is primarily that of a frontline melee specialist.

He fights with longswords, combining precise technique with overwhelming physical and magical power.

His leadership is especially important in large-scale operations, such as deep dungeon dives and joint raids with other S-Rank parties.

Even when burdened by doubt and manipulated memories, he shoulders the expectations of the world as a “Hero.”

Mana Convergence

Oliver’s unique ability is Mana Convergence, which allows him to gather surrounding mana into a single point.

This concentration of power can drastically enhance his attacks or be used to empower techniques and possibly spells.

By drawing in ambient mana, he can achieve burst-level amplification of his sword strikes.

This makes even basic slashes capable of rivaling high-level combat arts or magic.

Swordsmanship

Oliver’s main fighting style is close-quarters sword combat using a longsword.

Within the world of explorers, his swordsmanship is described as top-class, standing at the pinnacle among active adventurers.

He combines speed, precision, and power, maintaining full control over his blade even in chaotic melee scenarios.

When he channels converged mana into his sword, each attack carries both physical and magical force, enough to threaten high-tier monsters.

Because of this, he is commonly referred to as the Sword Saint, a title reserved for only the most elite swordsmen.

On the battlefield, he functions as both a breaker of enemy lines and a symbol of morale for his allies.

Oliver and Orun Dula were originally best friends and battle partners.

They shared hardships, victories, and dreams, culminating in their mutual vow to save the world together.

Even after learning he was artificially designed as a Hero throwback while Orun was the true natural throwback, Oliver’s genuine self never resented him.

Instead, he accepted his role and continued to fight side by side with Orun, driven by genuine friendship.

However, as the memory manipulation took deeper root, Oliver’s view of Orun started to change.

When they advanced through the floors of the Southern Great Labyrinth, doubts about Orun’s capabilities and contributions quietly grew.

These concerns intensified during a joint dragon subjugation mission involving three S-Rank parties.

During this operation, Oliver received buffs from Selma Clodel, and the contrast in performance left him convinced that Orun’s strength might not be sufficient.

Despite these conclusions, Oliver initially remained reluctant to cast Orun out.

The weight of their shared history and their promise made him hesitate, even while manipulated.

Influence of Annery Wiles and Derrick Mosely

Two of Oliver’s party members, Annery Wiles and Derrick Mosely, played a key role in tipping his decision.

They reinforced and amplified his doubts about Orun, pushing narratives that made Orun seem unworthy of the party’s high-level challenges.

Under the combined influence of their pressure and his altered recognition, Oliver finally chose to expel Orun from Golden Dawn.

This decision marked a turning point, shattering the visible bond between the two former partners.

Oliver is not a purely natural-born hero; he is a deliberately engineered individual.

He was created so that his lineage and abilities would revert toward those of the original Hero, effectively making him a man-made throwback.

When Orun Dula appeared as a genuine, naturally occurring Hero throwback, Oliver’s role was downgraded to that of a backup or spare.

In the eyes of those who designed or observed him, he became a contingency rather than the main successor.

This revelation could have crushed him, but in his true self, Oliver did not allow it to poison his friendship.

He continued to stand by Orun’s side, treating him not as a rival, but as a partner in their shared mission to save the world.

The tragedy is that this authentic loyalty was buried under a decade of altered memories.

The Oliver who expelled Orun was acting under a distortion of his true feelings, not his original heart.

At a later point in the story, the King of Abilities intervenes and frees Oliver from recognition alteration.

This power strips away the artificial changes that had been imposed on his memories and perceptions.

Once liberated, Oliver recovers all of his original memories, including the true nature of his relationship with Orun and their promise.

The guilt of having driven Orun out under false impressions weighs heavily on him.

Reclaiming his original self, he decides to support Orun from the shadows, using his influence and power for Orun’s benefit.

He moves quietly, often behind the scenes, seeking to repair the damage that manipulations and conspiracies have done to his former partner.

From that point onward, his role subtly shifts from the public “Hero” of Golden Dawn to a hidden ally working to help Orun Dula fulfill the destiny they once vowed to share.
