Ruijerd Superdia belongs to the Superd tribe, a warrior race marked by emerald-green hair, pale skin, and a crimson forehead gemstone that senses mana. A deep scar crosses his face, a relic of ancient battles. To mask his feared heritage—stemming from the Superd’s role in the Laplace War—he shaves his head and conceals the gem beneath a bandana. His weapon is a triple-bladed spear forged from his own calcified tail, a biological trait of Superd warriors that sharpens and strengthens with use.

Once a leader under the Demon God Laplace, Ruijerd was deceived into wielding cursed spears that drove him to slaughter, culminating in the accidental killing of his son during the war. Freed from control when his son destroyed the cursed weapon, Ruijerd joined Laplace’s defeat and swore to restore his tribe’s honor, tarnished by wartime atrocities.

After the Fittoa Region Teleport Incident, he journeyed with Rudeus Greyrat and Eris Boreas Greyrat, forming the adventurer party Dead End. They performed heroic acts under Ruijerd’s name to dismantle the Superd’s monstrous reputation. Over three years, their efforts softened societal hatred, weakening the curse tied to his tribe. Ruijerd adhered to a strict moral code, fiercely protecting children and allies while ruthlessly punishing harm to innocents.

Post-Disbandment, he traveled solo, seeking surviving Superd and advancing his mission. His 500 years of combat experience rivaled emperor-level swordsmen, though he recognized transcendents like Dragon God Orsted surpassed him. He trained Eris in battle tactics, emphasizing lethal intent and adaptive reflexes.

Ruijerd’s story revolves atonement for collective guilt and systemic discrimination. Motivated by his son’s death and his tribe’s cursed legacy, he dedicated centuries to reshaping the Superd’s identity. Incremental acceptance on the Central Continent marked tentative progress in his lifelong quest for redemption.
