Bambietta is a slender young girl with long, straight, dark brown hair and brown eyes and standing at a height of 5'7 and a half. Her attire is a variation of the Sternritter's typical white uniform, consisting of the order's signature hooded cloak, a thigh-length trench coat, knee-high boots, a miniskirt, and black stockings with a red trim on her gloves and boots.
