Ghislaine Dedoldia, a tiger-eared warrior of the beastkin Dedoldia Tribe, bears heightened senses and a tail marking her heritage. Daughter of Gustav, former chieftain of Doldia Village, her youth was defined by violent outbursts and an inability to resolve disputes without bloodshed, forcing her exile. Discovered wandering by Sword God disciple Gal Farion, she mastered his style under his tutelage, ascending to the elite rank of Sword King. Her prowess led her to Paul Greyrat’s adventurer band, the Fangs of the Black Wolf, where combat sharpened her skills and forged enduring bonds. Struggling with illiteracy and numeracy, she faced exploitation until a hunger for knowledge drove her to apprentice under Rudeus Greyrat. Tasked with guarding Eris Boreas Greyrat, she escorted Rudeus to Roa’s Citadel, serving simultaneously as Eris’s sword instructor, protector, and an abrasive yet caring elder sister. Unwavering loyalty to Eris’s grandfather, Sauros Boreas Greyrat, took root when he saved her from mortal peril. This debt compelled her to hunt his killers after the Teleportation Incident obliterated Fittoa and scattered survivors. For three years, she aided displaced refugees while tracking missing allies. Reuniting with Rudeus and Eris, she shifted focus to Eris’s growth, journeying to the Holy Land of Swords to refine her charge’s abilities under Gal Farion and other Sword God masters. In battle, Ghislaine wields Hiramune—a katana bestowed by Gal Farion—with lethal precision. Her signature Long Sword of the Light technique unleashes blinding flurries of strikes, augmented by agility surpassing most warriors. A concealed Demon Eye beneath her eyepatch detects mana fluctuations, countering magical threats. Though reliant on martial dominance, she learned rudimentary fire magic from Rudeus and slowly conquered her academic shortcomings. Stoic and intimidating, Ghislaine masks vulnerabilities beneath a battle-hardened exterior. Impulsive actions and fierce loyalty define her relationships, particularly toward those earning her respect. From a tempestuous exile to a disciplined Sword King, her journey reflects tempered brutality into mentorship. Though intellectual gaps contrast her combat genius, her evolution bridges vengeance-driven fury and steadfast guardianship, anchoring her role as both Eris’s blade and shield.
