Grey, a magic knight of the Black Bulls, conceals her true self beneath a veil of shyness and borrowed faces. Born into nobility, she suffered under a cruel stepmother and stepsisters who forced her into servitude. Desperate for connection, she mimicked their forms—only to face rejection. Fleeing home, she narrowly escaped bandits thanks to Gauche Adlai’s timely rescue, spurred by his sister Marie’s plea. This act drew her to the Black Bulls, where she slowly shed her isolation. Her transformation magic, rooted in mimicry, blossomed into alchemic mastery. Early battles saw her transmute boulders to meat to aid allies and reflect lethal spells with mirrored curtains. By reshaping magic attributes—poison to cotton, enemy attacks to harmless forms—she proved indispensable. This power’s true depth emerged when she healed fatal wounds by altering tissue at its core, revealing her magic’s alchemic essence. Shyness once dictated Grey’s every move, until her squad glimpsed her true appearance mid-mission. Resolving to abandon disguises, she fought alongside them against the Eye of the Midnight Sun and Spade Kingdom’s forces. Her ingenuity turned tides: unraveling Droa’s enchantments in the Elf Reincarnation Arc and neutralizing Morris’s demonic spells during the Spade campaign. Even in lighter tales, Grey’s presence shines. When a villain mechanized the Black Bulls, her robotic form merged into a mighty mecha to thwart a demonic menace. Bonds with comrades anchor her growth. Though indebted to Gauche, she long hid her identity from him. Alongside Gordon and Henry, her magic synergizes with theirs, cementing trust. This camaraderie emboldened her to reveal her real form in their darkest hour. Marked by a fondness for milk, a February 20 birthday, and a stature of 159 cm, Grey’s journey—from cowering mimicry to self-assured alchemist—epitomizes resilience forged in battle and brotherhood.
