Danganronpa V3: Killing Harmony (Demo)

Miu Iruma (入間 美兎 Iruma Miu) is a character featured in Danganronpa V3: Killing Harmony and a participant of the Killing Game Semester.

Miu is an inventor responsible for creating widely acclaimed products such as "Eye Drop Contact Lenses", though she considers them a failure since she had to work to create them. Despite this, she was still given the title of the Ultimate Inventor[1] (超高校級の「発明家」 chō kōkō kyū no “hatsumeika” lit. Super High School Level Inventor).

Before Joining Danganronpa
NDRV3 Cast Prologue

Miu Iruma is a normal talentless high school girl who participated in the 53rd Season of Danganronpa, a famous worldwide reality show made by Team Danganronpa.

Miu and the other talentless fifteen students undergo the fabrication process, where all of their past memory and personality were heavily fabricated. She also received the talent and title of Ultimate Inventor. All of this were done for the sake of satisfying Danganronpa's audience from all around the world. After the fabrication process done, Miu and the others entered the Ultimate Academy for Gifted Juveniles as a whole different person, officially commencing the 53rd killing game season known as the Killing Game Semester.

Students of Fabrication
Fabricated Past

After she successfully participated in the 53rd Killing Game, Miu's memories and past were fabricated by Team Danganronpa as follows.

Miu's career as an inventor included the commercialization of her "Eye-drop Contacts". However, because her principle motto is "how can you live life when you're so relaxed it's like you’re still asleep," she treats them as a failure.

The Gopher Plan

Main article: The Gopher Plan
The Gopher Plan V3 Kids
Part of the fake backstories created for Miu and the other fifteen students was the Gopher Plan, which supposedly happened before the killing game started. It was initiated by the government after countless meteorites crashed into Earth. To try and preserve the last vestiges of mankind before the Earth's destruction, the government decided to select a number of excellent human beings, put them in a spaceship, and have them escape.

Miu and fifteen other high school students were chosen to participate. Not wanting to abandon their loved ones, they attempted to escape from the plan.

Around that time, an extremist cult came into power. They believed that the meteor crashes were a punishment humanity brought upon itself, and having heard of the Gopher Plan, they tried to stop it. As a result, the “Ultimate Hunt” started and spread throughout the world, and the sixteen students were hunted down.

The Gopher Plan Fake Deaths

The government then decided to counter the situation by faking the students' deaths, calming down the “Ultimate Hunt” while providing protection to the students. The Gopher Plan was then put into action while the Earth was being destroyed. Miu and the others went to the space in a massive colony spaceship, the true form of Ultimate Academy of Gifted Juveniles.

Kokichi Oma, one of the participant of the plan, declared himself as a member of Junko Enoshima's Remnants of Despair who masterminded the Killing Game and let Monokuma entered the spaceship, effectively forcing Miu and the others to participate in the Killing Game.

It should be noted that Miu has no complete recollection of the event, as she was murdered before she actually received a complete memory about The Gopher Plan by the Flashback Light in Chapter 5.

When Kaede Akamatsu and Shuichi Saihara met Miu, she accused Shuichi of looking at "her tits". She said that all boys who wear hats are perverts, and Shuichi got frustrated with her, causing Miu to cower in fear.

After Miu introduced herself as the Super High School Level Inventor, she explained that she makes inventions that allow you to do things like eating while you are sleeping. She also said she accidentally made some eye drop contact lenses, and Kaede said one of her friends used them, which angered Miu, since she wasn't proud of that invention and sold the rights to a company.

Akamatsu and Saihara begged to Iruma

In Chapter 1, Miu agreed to invent a camera for Kaede and Shuichi to use as part of their plan to catch the Mastermind after they begged to her. After Rantaro Amami was murdered in the library where the camera was installed, Miu reminded them that they could use it to see who killed him, but the camera didn't catch the murder.

Iruma and her drone

During the investigation, she used a drone to capture the full layout of the library from above, this proves a key point in the later trial.

Miu was noticeably distressed when Kaede was revealed to have killed Rantaro, and she witnessed her brutal execution. She asked Angie Yonaga, who prays for Kaede to find peace, how she could rest in peace after such a horrible way to go.

Gonta encountered a nude Iruma

During the second trial, it was revealed that Miu had stripped to her underwear in an attempt to unnerve Gonta. Kokichi Oma had noticed Miu and described it as her having an "erotic time". Miu proudly proclaimed her reasoning and told Gonta that he should be glad he got to see her beautiful body, though it is clear that at the time, she was just as embarrassed as he was.

Iruma fixing Ki-Bo

Sometime after the second trial, Miu went to her Research Lab along with K1-B0 in order to install a lot of new functions to his body.

Miu was part of the students who antagonized Angie Yonaga's Student Council in Chapter 3, claiming God's existence to be unscientific. After Shuichi told her about the computer room, she started to spend day and night examining it, which was another cause of conflict with the Student Council due to their curfew rule.

New World Program

From the starting of Chapter 3, Miu was really busy in preparing her murder plan. Using the computer on the third floor, she created a parallel world that she dubbed as "paradise" where no killings will be committed. This was only her lie so she could commit a perfect plan.

Miu Iruma being Ironic 2

Once she completed her preparation in Chapter 4, Miu begged to everyone to enter the parallel world with her. She said that she already deleted everything that could be a murder weapon inside the parallel world and stated that there might be clues of the outside world. With this, all of her friends agreed and proceed to enter the parallel world.

Miu planned to kill Kokichi Oma in the virtual world killing game, and placed a bottle of poison on Kokichi's chair to make it look like he had been killed by the poison. However, Kokichi manipulated Gonta into killing Miu by strangling her avatar with a roll of toilet paper.

Creation and Development


Miu's first name can translate as "beautiful rabbit" - possibly referencing her two ahoges. Her last name, "Iruma", can be loosely translated as "entering space," but can also refer to the name of a city in Saitama perfecture.

Alternate Fates

In Danganronpa V3: Killing Harmony (Demo Version), Miu was first seen inside the girl's bathroom. She introduced herself as the mighty, greatest inventor all of time to Kaede Akamatsu. In instant, Miu nicknamed her as "Miss Piggy/Pig Tits" and bragging about useful products that she invented.


Miu Iruma Fullbody Sprite (Special)
NDRV3 Art Gallery Miu Iruma

Miu is a tall young woman with long blonde hair and a pair of ahoges. She has bluish-grey eyes. 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 colored goggles on her head. She wears a pink sailor school uniform and matching skirt. She wears black fingerless gloves and black boots with gold buttons on them. The buckles on the boots are also gold. She wears black straps connected by gold rings on her legs, and over her clothes. The straps for her legs have gold clips that are attached to her white socks. She wears a black choker collar, and two smaller black collars, around her neck. On her collar, she wears a blue bear pin with a red ribbon wrapped around its neck.

In the box art, Miu has a brown backpack that has two long metal arms coming out of it.

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. 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, her 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.[3] Because of this, she has the charm similar to an innocent child.[4]

As an inventor, she 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".[5] 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.

She also appears quite perverted and openly says bizarre, obscene things during her arrogant mood.

However, she is secretly a masochist and into BDSM, and acts very different during her weak-willed moments. Despite her usual arrogant behavior, she seems uncomfortable if other people actually act very submissive towards her. She also appears to have some sort of fetish for machines and is very 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 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. 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 Oma because she believes the world needs her, while claiming to have no personal grudges against him. She also shows severe trust issues during a flashback conversation with him, and her love hotel event implies she might suffer from 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.

Miu's talent as the Super High School Level Inventor is a fabrication made by Team Danganronpa. Due to that fact, it is unclear whether Miu is a supreme inventor in the past.
Spoilers end here.

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.[6]

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 than 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.

With Miu being quite disliked in the group, K1-B0 appears to be the only student, other than Kaede and Gonta, who genuinely likes her and wishes to be friends with her.

Because he is a robot, Miu took a special interest in K1-B0 and even appears to feel sexual attraction towards him, though it's unclear if he is aware of this. As her talent would indicate as such, she would often perform maintenance on him, in a rather suggestive manner they both seem to find very pleasurable. Her intense personality makes K1-B0 feel very shy and he blushes a lot due to Miu's compliments and remarks, and Miu in turn thinks he is cute. Being very interested with K1-B0's talent and features, Miu went inside his talent research room without his permission. Besides that, she added many new features to K1-B0, such as flashlight that came out from his eyes. She also wishes to give him a vibration function, but he declined.

While Miu is very openly attracted to K1-B0 and seems to think their relationship is something similar to being a couple, it's a bit unclear how he feels about her, as he doesn't really speak of her in an explicitly romantic manner like he does with Shuichi in the Bonus Mode. He does not seem to be fully aware of some of her implications, but genuinely cares about her and is very grateful for her help. It is also possible that he likes her back, but isn't aware of it.

K1-B0 was shocked when he discovered Miu's corpse in Chapter 4 and he was the only one to still speak fondly of her even after the chapter.

In the bonus mode, the two appear to be close as well, and Miu takes care of K1-B0's maintenance for their three high school years. K1-B0 tells her how grateful he is and that he will miss being able to ask her in the future. Miu is very offended by this, asking K1-B0 why he's going to throw her away, and assumes that he has other partners than her. K1-B0 tries to explain they're graduating soon, but Miu is still angry. He then tells her that it would be good to have someone like her who is good with technology to care for him. Miu answers that he can come to her place and the two agree to continue their usual habit, with K1-B0 thanking Miu in advance.

Kokichi Oma

Miu feels irritated by Kokichi and believes that he is the mastermind. She thinks he is a compulsive liar and tends to insult him by calling him a shota in the original Japanese release. While Kokichi appears to otherwise dislike Miu, he likes to insult her and push her around during her weaker moments. In her relationship chart, he orders her to get on her knees.

In chapter 2, Kokichi witnessed Miu in the dark, walking around in her underwear in the courtyard, as a tactic to escape Gonta. During investigation, Kokichi tells the others about the situation and how strange it was, with him appearing visibly disappointed. He later mocks her during the trial for being perverted.

In chapter 4, Miu attempted to murder Kokichi in the virtual world killing game and placed a bottle of poison on his chair to make it look like he got poisoned. However, Kokichi lured Gonta into killing Miu by strangling her with a roll of toilet paper. Later when Gonta was found as a culprit, Kokichi told Monokuma to execute him as well which could prove that Kokichi regret what he did but it can be hard to tell if that was part of his lying nature.

Despite her murder attempt, Miu claims to have no particular ill-intent against Kokichi.

Kaito Momota

Being the two loudest and outspoken characters, they get into disagreements. These disagreements can cause them to throw insults at each other. During the Danganronpa V3 demo, Miu calls Kaito a "flower-garden brained idiot." Because these two can get emotional, both can end up losing their tempers, with Kaito scaring Miu in the end.

Kaede Akamatsu

Miu and Kaede's relationship can be a bit negative at times, as Miu has a tendency to insult her just like she insults everyone else, and specifically calls her "Kaeidiot" (Bakamatsu in Japanese) and keeps calling her breasts tiny. However, while Kaede can be a bit annoyed by Miu's rudeness, she feels sympathetic and protective of her whenever she shows her weaker side.

In Chapter 1, when Kaede begs on her knees for Miu's help, Miu appears uncomfortable despite her usual arrogant behavior. When she agrees, the former grabs her hands in joy and causes Miu to sweat.

In Miu's second Free Time Event with Kaede, Kaede appears worried of Miu, because it seems like she has never had any friends, and wishes to help her to become better at communicating.

Miu is also noticeably distraught after Kaede is found guilty.

Miu appears to feel some attraction towards Kaede. During their first Free Time Event together, Kaede has finally had enough of Miu's rude behavior and she tells Miu that her breasts are actually pretty big. Miu then wants to rub her to make sure, saying there's no problem because they're both girls, but Kaede is uncomfortable and smacks her a little in order to defend herself. Later, in Chapter 3, Miu also tries to see if the wax figure of Kaede that Angie made is wearing any underwear.

Shuichi Saihara

When Shuichi and Kaede first approached Miu, she assumed that Shuichi was staring at her breasts. Miu then called Shuichi a pervert and that was why he wore a hat. However, Shuichi then stands up for himself and Miu gets startled by this as she thought he was a weakling.

During the Love Hotel event, Shuichi had the role of Miu's childhood friend. Miu tells Shuichi that she would allow him to sleep with her.

Shuichi asks her what she meant and Miu becomes annoyed and sad and wonders how he could be her childhood friend if he couldn't remember. She explains that when they were younger he always took care of her and still to this day. She says that he is the only one who knows her true self and he helped her to become the Super High School Level Inventor. Miu then says she wants to have Shuichi's kids and he immediately becomes shocked again. Miu then says how talented their kids would be with both of their talents combined. Shuichi becomes silent and Miu gets upset again as she thinks she's not good enough for him and wants to have his kids so he can't get rid of her. Shuichi begins to stutter as Miu tries to force him into having sex with her. Miu then moves towards Shuichi. It is implied that they slept together afterwards.
