Eris Greyrat

Eris Boreas Greyrat is a powerhouse whose transformation from a volatile, feral noble child into an elite, fiercely loyal warrior defines much of the emotional and action-driven weight Initially known as the "Mad Dog" of the Boreas noble family due to her explosive temper, violent outbursts, and absolute refusal to conform to high-society expectations, her life shifts dramatically under the tutelage of her cousin, Rudeus Greyrat. Over years of surviving the brutal perils of the Demon Continent alongside Rudeus and the legendary warrior Ruijerd, her childish aggression matures into a profound, deeply protective love for Rudeus. However, a traumatizing, near-fatal encounter with the catastrophic power of the Dragon God Orsted shatters her confidence, making her realize she is too weak to protect the person she loves most. Driven by this agonizing realization, she leaves a misunderstood goodbye note that breaks Rudeus’s heart and exiles herself to the Holy Land of Swords for five years of unrelenting, brutal training. Through sheer, singular willpower, she sheds her aristocratic past to master the devastatingly fast Sword God Style, ultimately earning the legendary title of Sword King. When she finally returns to Rudeus's side, she is no longer a liability but a fierce, peerless vanguard shield—eventually becoming his third wife, a dedicated mother, and an indispensable force in the battle against the dark orchestrations of Hitogami.
