• She is a young woman with short, light-blue hair (usually styled in a bob with a distinctive ahoge/strand sticking up) and matching blue eyes. • She has a single visible horn on the right side of her forehead (her left horn was broken in the past). • She typically wears a classic black-and-white maid outfit with a frilled apron, She is generally polite, diligent, soft-spoken, and extremely loyal. Early on she can come across as somewhat reserved or even cold, especially toward Subaru, but she gradually reveals a much warmer, deeply caring, and somewhat shy side. She carries a lot of guilt and an inferiority complex related to her sister Ram (whom she idolizes) and past events involving their Oni village. Despite this, she is highly competent in combat, housework, and healing magic, and she is fiercely protective of the people she cares about. She also loves to be praised.
