A Sword God Style swordsman with the rank of Sword Saint. The daughter of the Sword God, Gal Farion. She has a dignified face with dark skin and flowing dark blue hair tied behind her neck, giving her the appearance of a female warrior. While proud and confident, she behaves politely toward superiors. Possessing talent said to be unrivaled even in the Holy Land of Swords, she follows the Sword God Style philosophy of a single lethal blow—defeating enemies without unnecessary movement by swinging the sword at maximum speed. However, she lacked actual combat experience; even after losing to Eris, she failed to distinguish between a match and a real fight, claiming she wouldn't lose easily under proper rules where dropping or breaking a sword constitutes defeat. Despite her short-tempered and extreme personality, she is a serious and sensible person who behaves politely to superiors, waits quietly in line for duels, and offers objective opinions.
