Madness Enhancement has robbed her of most of her linguistic ability, limiting her responses to head-shaking and grunts; the only time she was able to speak was when she was summoned and when she was trying to kill herself along with Saber of Red using her Blasted Tree. She can differentiate friend and foe, and she is able to communicate simple ideas. Due to a lack of skill in expression, and fearful of her own monstrous nature, she maintains a shy silence that conceals her high intelligence and empathetic capabilities, except for the emotion of sorrow. She prefers to remain in material form, and she sullenly moans when forced by Caules to remain in spiritual form. Rather than running wild, she prefers to pick flowers in the castle's courtyard garden or stare at the sky. She dislikes the overly-friendly Rider of Black, only rarely responding to his inquisitive attempts to speak with her out of annoyance. Extremely mindful of energy conservation, she will turn off the lights in the bathroom if her Master leaves them on after use and directly unplug the PC's power plug.
