Murasaki is a striking Taimanin with long blue hair that fades to purple at the tips, and piercing red eyes. She cuts an imposing figure in her white battle suit, which in her youth was open at the thighs and later gained a vertical black line. Her expression is often stern, and her tongue is sharp, with little tolerance for foolishness. Yet beneath this cold exterior lies a fiercely protective and loyal heart, especially toward her students and friends. She takes her training seriously and even enjoys a good fight, occasionally letting a rare smile slip as she cuts down enemies. While hard to approach, those who earn her trust find a thoughtful and kind ally willing to endure humiliation for their sake.
