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, Miu's arrogant personality seems to be only a mask that can drop fairly easily, becoming meek and scared. Miu comes off as very perverted and openly says bizarre, obscene things.
