Major
First seen · Book 3 · Ch. 1

A sixteen-year-old girl with straight black hair cut sharply across her eyes and shoulders, her face and hands marked by pale scars from countless battles. She wears a tattered black robe cinched by a vivid blood-red rope belt, with a gleaming silver bladed arm extending from her shoulder like a scorpion's stinger. Her posture is always deadly and coiled, as though ready to strike at any moment.

Yerin evolves from a scarred, battle-hardened Highgold disciple carrying her master's Remnant into a formidable Underlord whose six silver sword-arms and crackling aura mark her as a rising star of the Blackflame Empire. Across the books, her combat instincts deepen, her Blood Shadow becomes both a dangerous liability and a potent weapon, and her bond with Lindon shifts from shared training to a romantic partnership that fuels both their advancements. By the Uncrowned tournament, she stands as a determined competitor whose scars and sword-arms tell the story of relentless growth under Eithan's unorthodox guidance.
