Miu is described as an oddball, having an overly confident, loud personality and a frighteningly sharp tongue. She considers herself a beautiful genius, and every time she opens her mouth she spews a parade of reckless vulgar remarks and insults, strongly putting pressure on others and looking down on them. However, she is shown to be very weak willed and timid if confronted or insulted back, and dislikes people being too submissive to her. She hates taking it easy, but also hates hard work.
