Miu Iruma (入間 美兎) is a student in the Ultimate Academy for Gifted Juveniles and a participant of the Killing School Semester featured in Danganronpa V3: Killing Harmony. Her title is the Ultimate Inventor (超高校級の「発明家」 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, and a faded pale blue bow tied at her collar. Her chest cover is noticeably missing, leaving 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. In the box art, Miu carries a metal backpack hanging from her shoulders, two long metal arms extending from it, lighting a red candle- presumably one of her inventions. In the Prologue, Miu wears a white blouse with a messily unbuttoned collar, an orange plaid ribbon sloppily tied into an uneven bow. Her blouse sleeves are rolled up to her elbows, and the shirt is tucked beneath her brown, plaid pleated skirt. She has two orange hairpins on the right side of her bangs. She wears dark teal knee-high socks and black penny loafers.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, and would routinely call them virgins. However, Miu's arrogant personality seems to be a mask that can drop fairly easily. This often happens when her festival of coarse language and dirty jokes actually get replied to (usually, with the person snapping back) or ignored. Then, her personality quickly changes into a timid coward, who is terrified of other people being angry with her. Because of this, she has a charm similar to an innocent child. 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 both inside and outside of the Killing Game, but only deems her inventions as a success when they help the user to perform a task while sleeping (it's possible this is because she suffered from a coma in the past). She also has a habit to make very bizarre, seemingly pointless inventions which are sometimes very sexual in nature, including a "Hookup Counter" which tells how many people you've had sexual intercourse with, an "Auto-Puncher that Punches You for Telling Terrible Dirty Jokes", and a "Goin' Commando Gun" which can teleport underwear and only underwear. Even seemingly innocent inventions such as the electrohammers and the electrobombs can have dirty innuendos, as in the Japanese version the word "elect"
