Her title is the Ultimate Inventor lit. Super High School Level Inventor.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 exposed. Her previous high school's 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, a pin of the mouse mascot from Niko Niko Happy on her collar, 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.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. In the original Japanese, she even uses the Japanese word "ore-sama" to refer herself, which is considered very arrogant and more traditionally masculine. She also tends to give other characters insulting nicknames
