Miu Iruma is a character from the Danganronpa V3: Killing Harmony video game.
An inventor on the cutting edge. She has a rather strange set of priorities—for instance, some of her favorite inventions are a series of devices that make it easier to eat or read while sleeping, while she considers her truly groundbreaking "eyedrop contact lenses" boring and sold the patent. She is incredibly brash and vulgar, but despite this, she will suddenly turn into a wimp if her facade is successfully attacked.
Wanting to get away from the chaos of the killing game, she modifies the academy's Neo World Program to allow for the cast to instead live in Virtual Reality where the risk of death is minimal, though it is later revealed that she was intending to use the program to kill Kokichi Ouma in an unsolvable murder. She is the victim of Chapter 4, strangled to death within Virtual Reality by Gonta Gokuhara, who was manipulated by Kokichi into thinking he was performing a mercy kill.
In the XP4 fics, Miu is brought back to life. Miu is a member of the Heroes Coalitions as a trainee. She also attends at the Vanguard Academy as student.
Miu is a tall young woman with long strawberry blonde hair and two ahoges. She has icy blue eyes, and her irises, as well as the rings around her pupils, have an unusual, ragged pattern, making them appear slightly mechanical-looking and thus possibly referencing her talent.
Miu wears brown goggles with yellow accents on her head. She wears a modified pink sailor school uniform and a matching skirt, her collar noticeably exposing her cleavage, lacking the cover on her chest. She wears black and studded fingerless gloves, with black heeled-boots with gold buttons and buckles on them. She has black straps connected with gold rings attached to her white socks, and over her clothes, gold ring covering her blue ribbon around her collar. She wears a black choker, and two smaller black collars that resemble barbed wire made out of rubberaround her neck. On her uniforms collar, she wears a pin of the mouse mascot from Niko Niko Happy.
In the box art, Miu has a metal backpack hanging from her shoulders that has two long metal arms extending from it, lighting a red candle
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.
However, Miu's arrogant personality seems to be only a mask which can drop fairly easily. This often happens when her festival of coarse language and dirty jokes actually get replied or ignored. Then, her personality quickly changes into a timid weakling, who is terrified of other people being angry with her.Because of this, she has the 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 amazing conviniences both inside and outside of the 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 very sexual in nature, including a "Hookup Counter" which tells how many people you've had sexual intercourses 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 Electrohammers and Electrobombs can have dirty innuendos, as in the Japanese version the word "elect" can also be read as "erect". Nevertheless, Miu has also used her remarkable talent to make very useful inventions as well, though in most cases they were concepts created and requested by other students or something she created because she was bored. It is also shown that as an inventor, she firmly believes in science and finds Himiko's insistence in magic and Angie's talk about Atua very annoying.
Created to be the "naughtiest character in the series' history", Miu appears very perverted and openly says bizarre, obscene things during her arrogant mood, meaning almost constantly. She often claims that she just says them to lighten up the mood, but they are very much disliked by the other students. Despite often trying to act dominant and appear sadistic, Miu is also masochistic and into BDSM, and acts very different during her weak-willed moments. Despite her usual arrogant behavior, she seems very uncomfortable if other people actually act very submissive towards her, like when Kaede and Shuichi begged for her help and she begun to sweat nervously and agreed just to make them stop (though she later claimed that the situation turned her on). She has many kinks, some of which she seems to casually admit, including bondage and hot wax (which is also seen in her official art). She also seems way too interested in her own feces. She appears to have some sort of fetish for machines as well and at one point she is seen acting very suggestive towards a computer, and she is also very much attracted to K1-B0. Furthermore, in her last free time event with Shuichi, she tries to give him a pie with her hair in it. She also baked cookies with her fingernails and made chocolate with her blood as ingredients. Disturbingly, she says that she wants the person she loves to eat a little piece of her.
Miu has a very cowardly and self-centered personality, immediately looking for excuses to be absent from the Class Trial after being reminded that she would be executed with everyone else if they reach the wrong conclusion. Also, despite her amazing inventive genius, she is rather dumb when it comes to other matters, being usually ignored by the other characters during the trials. During investigations and trials, 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. Because of this, Himiko has described her as "really smart, but also really, really dumb". She is generally not liked in the group, and according to Kokichi, she is the least well-liked student after him. During her trial, many students admitted that they probably wouldn't have been friends with her even if they had met outside the Killing Game.
Despite her timid personality, she genuinely believes her bragging, to the point she is willing to kill Kokichi because she believes the world needs her while claiming to have no personal grudges against him. Though, it should be noted that she seemingly wished to help the world and its people with her inventions (which are proven to be very remarkable) after learning about the meteors and how bad the situation on Earth supposedly is. During her Free Time Events, it's revealed that she is convinced she is an augmented human as a result of surviving a coma and a surgery, which supposedly explains some of her behavior. She has been shown to act in self-destructive manner at times, believing she cannot be harmed nor killed in the same ways as ordinary humans. During her Free Time Event, she even attempted to disembowel herself with a wrench because she believed that her superhuman powers were literally inside her and she wanted to study them. During her introduction, it's also heavily implied by her own words that she had a tendency to use powerful hallucinogenic drugs in highly stressful situations, to make herself forget all about it. When she much later talked to Shuichi in her usual odd manner, Shuichi felt worried and suspected that she might be on drugs.
In a flashback conversation with Kokichi, Miu is also shown to suffer from trust issues and fear of betrayal after everything that's happened in the killing game. Her Love Suite event implies she might suffer from strong abandonment issues. The aforementioned event and her behavior towards Monotaro might also indicate that she likes children. According to Kaede, Miu may have trouble with communication because she has never had any friends. According to K1-B0, Miu is a good person and has natural innocence hidden deep inside her, despite how she appears on the outside, and it's implied that she acted more like her true self in K1-B0's company.
Miu's talent as the Ultimate Inventor is a fabrication made by Team Danganronpa. Due to that fact, it is unclear whether Miu is a supreme inventor in the past.
Miu is a very skilled inventor, and she has created lots of ground-breaking products, her first invention being "Eye-Drop Contacts".
Miu also invented many useful products such as a product that can help one to type on the keyboard, reading manga and understand it, and eating meals all done while the user is sleeping. She makes automatic sensor cameras at Shuichi Saihara's request and several items for Kokichi Oma, such as the machine-disabling Elect Hammers and Elect Bombs, a remote-controller that can hijack Exisals and a vacuum cleaner that can capture and release Monochicchis. Her Elect Hammers prove very useful when her friends manage to complete the tunnel dungeon in Chapter 5.
She also performs regular maintenance on K1-B0, including adding new functions, like lamps and a photographic camera.
- Miu has an unused sprite in which she holds a disturbing spiky dildo in her hand. This sprite was first discovered within in the game files. According to Kodaka, it was going to be used for her most angry moments, but they were "forbidden to use it for ethical reasons".
- Miu and Ryoma are the only Class Trial Participants that never join Kaede or Shuichi's side in Debate Scrums.
- Miu's Death Portrait from Chapter 4 onwards is adorned with 3 x's, usually signifying sexual adult content, which reflects her personality when she was alive.
