Grey

Grey is a petite young woman of average height, characterized by her light blue bob haircut, with several strands framing her face. She possesses an hourglass figure, with below-average breasts, a narrow waist, and a notably large, plump, and round posterior. The soft flesh of her hips and rear tends to jiggle with even the slightest movement, whether she is shifting her weight or simply walking, though she appears entirely unaware of the effect her body has on others.

She wears a white sleeveless shirt paired with dark blue, high-waisted pants that cinch just below her knees. The waistband is decorated with five connected flower motifs, with the largest flower positioned at the center and progressively smaller flowers extending outward on each side. Above the central flower are three vertically aligned flower-shaped buttons. Completing her outfit is a brown belt fitted with a pouch on her left side, where she carries her grimoire, along with a pair of dark blue flat shoes adorned with flower decorations similar to those on her pants.

As a member of the Black Bull squad, Grey also wears the squad's signature hooded robe, which is relatively short and bears the Black Bull insignia on the left side.

In her first revealed transformation, Grey takes the appearance of an extremely large, heavy-set man with slicked-back black hair, glowing eyes, and dangling spherical earrings connected by chains to smaller spheres. Much of the form's remaining appearance is obscured by heavy shading.

Despite her unusual magic, Grey is an extremely shy and timid person in her true form, becoming easily embarrassed in social situations. When transformed into someone else, however, she becomes far more outgoing, friendly, and cooperative, often enjoying working alongside her squadmates. She also tends to imitate the personality, mannerisms, and behavior of the person she is mimicking, demonstrating remarkable observational abilities and acting skills.

Grey is incredibly kind-hearted, though somewhat naïve. Despite enduring years of verbal and emotional abuse from her stepmother and stepsisters, she continues to hope that their relationship can be repaired. She even attempts to befriend her older stepsisters by transforming herself to resemble them, highlighting both her compassionate nature and her inability to fully recognize the cruelty and shallowness of their personalities. She fails to anticipate the negative reactions her transformation magic might provoke, further reflecting her innocence.

It is strongly implied that Grey's shyness stems from deep-seated insecurity and a lack of self-confidence. These feelings were shaped by the physical and emotional abuse she suffered at the hands of her stepmother and stepsisters throughout her childhood, leaving lasting scars on her self-image and sense of worth.
