Miu is 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. This often happens when her festival of coarse language and dirty jokes get ignored, she becomes embarrassed. Miu is a tall young woman with an hourglass figure and a fair complexion. She has waist-length strawberry blonde hair that flows in waves around her back, with two short locks of hair sticking up at the top of her head, sweeping to her right. Her bangs are long and wispy, swept somewhat to her left. She has shaky ice-blue eyes. Her head accessories consist of a pair of brown goggles with gold accents. Miu wears a modified, long-sleeved, dark pink seifuku uniform with a white sailor collar and sleeve cuffs, both striped with a single faded pale blue line, a faded pale blue bow tied at her collar. Her chest cover is noticeably missing, her cleavage mostly exposed. A symbol can be found in black printed at the shoulders of her sleeves. She wears a short, dark pink pleated skirt the same color as her uniform, vertically striped, off-white, knee-high socks, and black heeled boots accented with gold buckles, studs, and buttons. Her accessories include a black choker, two rubber collars that resemble barbed wire, black fingerless gloves studded with silver, black straps connected with gold studs wrapping her left upper arm, and black straps studded with gold linked with gold rings around her torso and legs. She also tends to give other people she meets vulgar and/or insulting nicknames, and would routinely call them virgins. As an inventor, Miu is skilled but also an eccentric who treats her failed projects with the idea that "I transferred the rights to the company, so it's got nothing to do with me". She has made all kinds of amazing conveniences She appears to have some sort of fetish for machines as well, at one point speaking suggestively about a computer, and she is also very much attracted to robots, but maybe not as much as humans. Furthermore, during her past, she once baked cookies with her fingernails and made chocolate with her blood as ingredients for her crush before. Disturbingly, she says that she wants the person she loves to eat a little piece of her, which might show how even though she acts strange at times, she doesn't want people to be grossed out by her. she generally spouts out whatever theories come to her mind at the moment without thinking them through, and she can make rather unwise decisions and actions.Miu was also shown to suffer from trust issues and fear of betrayal and people leaving her. Despite her timid personality, she genuinely believed her bragging, thinking she can change the world with her inventions and that she is truly important to humanity despite her amazing inventive genius, she is rather dumb when it comes to other matters, being usually ignored. Miu has a very cowardly and self-centered personality. Despite her penchant for calling those around her virgins, openness about her kinks, and tendency to make obscene remarks, it is suggested that Miu actually is a virgin herself; and her own love life is quite unsuccessful, if not nonexistent, and she gets extremely defensive when somebody tries to suggest that Miu is a virgin.she has never faced a serious opportunity for sex. Despite her hornyness, Miu wants love and not just sex, Miu is quite desperate too, and easily falls in love with anyone who is at least somewhat affectionate towards her. Mus inventions are all sexual in nature as she has kinks such as BDSM and hot wax, she is open about these topics and seems to enjoy talking about sex and kinks.
