History Characters / DanganronpaMiuIruma

* SpellMyNameWithAnS: A kanji variation. The Famitsu that revealed her name had it typoed as 未兎 instead of 美兎.

* CombatPragmatist: In Chapter 4, she pulls the dirty trick of stopping Kokichi from fighting back against her with his virtual avatar by setting him to be paralyzed if he ever touched her. She underestimates Kokichi in this regard, since he finds a way around this by using someone else who ''can'' touch her avatar to kill her instead.

* DressedLikeADominatrix: Reflecting her being into BDSM, Miu incorporates leather straps, a choker, two barbed wire collars, and high heel boots into her school uniform. She may definitely look the part, but in terms of ''personality''... well, Miu certainly ''tries'' to act dominant (and she is, at least when with Keebo), but she is actually very submissive; it is not too difficult to reverse positions on her (she becomes submissive to Kirumi, who has the subservient role of a maid, and Mikan, who is very meek in general), and she implies that she ''prefers'' being submissive.

* RunningGag: Whenever Miu invents something that is not perverted, there is a good chance that it allows you to do something while lying down.

* GoneHorriblyWrong: Her attempt at murdering Kokichi of all people, though he was pretty much her only plausible option for a murder victim, only ends up getting her strangled to death by Gonta's avatar instead. The only reason her murder attempt even happens in the first place is thanks to her ''also'' failing to gain the trust of the other students, or much rather their failure to gain ''Miu's'' trust.

** On another note, Keebo reveals that he has recorded all her deeds and stored them in his memory bank and reports that she has a natural innocence hidden underneath her loudmouthed front, implying that anyone who has the patience to bear with Miu and her antics will eventually see that she is fundamentally a sweetheart who just happens to have very extreme sides. Her Free Time Events with Kaede and Shuichi and her Love Suite Event support this as they reveal that Miu is a girl of [[InferioritySuperiorityComplex many insecurities]] who genuinely wants people to like her; what prevents this is her [[NoSocialSkills social ineptitude]] and [[InnocentlyInsensitive general lack of tact]], not helped by her FriendlessBackground. As the two spend enough time with her, Miu warms up to them and makes it clear that she enjoys their company; she just tends to sound insulting even when she tries to be nice. When Kaede tries to teach Miu how to talk to other people normally, Miu becomes grateful and develops a ''slightly'' better understanding, though she will make another joke about Kaede being "flat." Likewise, Shuichi, one of her frequent VirginShaming targets, assures an insecure Miu that her inventions are incredible (he just finds a lot of them absurd to the point of being impractical). With that, she decides to treat him "real good" from there, though she will still call him a virgin, and she eventually falls in love with him. She also gives him one of her inventions for free, highlighting her more generous side.

* ThePerfectCrime: Zigzagged but invoked nonetheless. On the one hand, Miu targeted the smartest student in the class, set up his obvious adversary to be framed, fabricated ''two'' layers of alibi, and (most crucially) planned the murder to occur in a location that neutralizes the Ultimate Detective: a virtual world where only she has access to, and furthermore can delete decisive evidence. Had she succeeded in her kill, Miu would have been entirely capable of deleting the murder weapon, the cellphone, and the special settings on the avatars, and she could doctor the log records to cement her alibis. On the other hand, her execution of the plan was assisted by Kokichi manipulating the class when they doubted her, and even her own real-time performance was notably suspicious: Miu's reaction to being called out as making the maps catches Shuichi's attention as "off" and Himiko outright calls Miu's incomplete coordination of the group as "sloppy". Not to mention aiming for the smartest student backfired and resulted in her becoming the victim. In the end, the class all around agrees on how difficult it would have been to catch Miu as a culprit, even with her behavior that draws attention, as there could be ''only'' speculation with ''no actual proof'' that Kaito's testimony was true nor that her alibis were false.

'''Miu:''' [wincing] Grgh!

** On another note, Keebo reveals that he has recorded all her deeds and stored them in his memory bank. He reports that she has a natural innocence hidden underneath, implying that anyone who has the patience to bear with Miu and her antics will eventually see that she is fundamentally a sweetheart who just happens to have very extreme sides. Her Free Time Events with Kaede and Shuichi and her Love Suite Event support this as they reveal that Miu is a girl of [[InferioritySuperiorityComplex many insecurities]] who genuinely wants people to like her; what prevents this is her [[NoSocialSkills social ineptitude]] and [[InnocentlyInsensitive general lack of tact]], not helped by her FriendlessBackground. As the two spend enough time with her, Miu warms up to them and makes it clear that she enjoys their company; she just tends to sound insulting even when she tries to be nice. When Kaede tries to teach Miu how to talk to other people normally, Miu becomes grateful and develops a ''slightly'' better understanding, though she will make another joke about Kaede being "flat."

With that, she decides to treat him "real good" from there, though she will still call him a virgin, and she eventually falls in love with him. She also gives him one of her inventions for free, highlighting her more generous side.

** "Pig-face" for Teruteru.

** On another note, Keebo reveals that he has recorded all her deeds and stored them in his memory bank. He reports that she has a natural innocence hidden underneath, implying that anyone who has the patience to bear with Miu and her antics will eventually see that she is fundamentally a sweetheart who just happens to have very extreme sides. Her Free Time Events with Kaede and Shuichi and her Love Suite Event also reveal that Miu is a girl of [[InferioritySuperiorityComplex many insecurities]] who genuinely wants people to like her; what prevents this is her social ineptitude and general lack of tact, not helped by her FriendlessBackground.

With that, she decides to treat him "real good" from there, though she will still call him a virgin, and she eventually falls in love with him. She also gives him one of her inventions for free, highlighting her more generous side.

* {{Kodomomuke}}: Miu's report card shows that she likes watching this. This ties in nicely with both her childish behavior (her juvenile insults and nicknames) and her fondness for children (her tenderness towards her "son" Monotaro).

** In ''Ultimate Summer Camp'', Miu gets angry at Mikan, who then tells her that she is free to write mean words on her. At that moment, Miu awkwardly declines and says that she prefers ''being written on'', suggesting that she prefers being submissive. Her aggressive-submissive trait gets lampshaded by Fuyuhiko after Miu orders Kirumi to massage her, do maintenance on the Monokubs, and do a system check in the outside world. Kirumi—note that she is a maid, a ''subservient'' role—agrees to do the first two tasks but firmly orders Miu to do the third one herself, leading Miu to quickly back down and comply.

** Miu and Mikan Tsumiki, again from Danganronpa 2, both fill in the role in their respective games as the ShrinkingViolet. Both are very meek and break down at the first sign of trouble, yet have a genius intellect using it to benefit others, with Miu's inventions helping out with the investigations and Mikan being the coroner of class 77. They also fall victim to the bullies of their respective games (although Miu is also a ThinSkinnedBully whereas Mikan is disturbed yet still very friendly towards everyone). In addition, they're highly sexualized, which is a key aspect of both of their characters, as both have a strong desire for attention and are scared of being ignored. Hilariously in ''Ultimate Summer Camp'', Miu hits her hand while snapping at Mikan, shortly after having it treated, and Mikan has Miu bend her wrist in certain ways, ostensibly to check for new injuries. Miu then discovers how much Mikan loves having control over her patients, much to her horror.

** On another note, her Free Time Events with Kaede and Shuichi and her Love Suite Event reveal that Miu is a girl of [[InferioritySuperiorityComplex many insecurities]] who genuinely wants people to like her; what prevents this is her social ineptitude, namely her tendency to act in terrible taste by saying anything and everything that comes to mind, not helped by her FriendlessBackground. As the two spend enough time with her, Miu warms up to them and makes it clear that she enjoys their company; she just tends to sound insulting even when she tries to be nice. When Kaede tries to teach Miu how to talk to other people normally, Miu becomes grateful and develops a ''slightly'' better understanding, though she will make another joke about Kaede being "flat." Likewise, Shuichi, one of her frequent VirginShaming targets, assures an insecure Miu that her inventions are incredible (he finds a lot of them absurd to the point of being impractical). With that, she decides to treat him "real good" from there, though she will still call him a virgin, and she eventually falls in love with him. She also gives him one of her inventions for free, highlighting her more generous side.

* BrutalHonesty: Miu does not sugarcoat what she's thinking. At all. Kaede and Toko call her out on it, but Hiroko Hagakure and Shirokuma admire her for speaking her mind.
-->'''Hiroko:''' That Miu sure is one-of-a-kind. I've never seen a girl so free in both words and mannerism.

* DropTheHammer: Miu smuggles a hammer into the Virtual World to kill Kokichi, but Gonta gets the drop on her before she can use it.

** From her interactions with Monotaro, she also genuinely likes children and desires to be a mom. Her apparent love for children is further supported by her character bio stating that she likes [[{{Kodomomuke}} children's television]], and her Love Suite event, stated above, shows that she does want to have children of her own (although in the latter case, it is more primarily driven by her fear of being abandoned). Miu's interactions [[WantsToBeHated Jataro]] and a comment about [[FormerChildStar Kotoko]] might suggest otherwise, but that might be because the Warriors of Hope exhibit TroublingUnchildlikeBehavior anyway, and even so, Miu ''does'' offer to teach Jataro how to make a contraption that feeds him popcorn while in bed after she notices him watching her make one.

** In a more comical version of this trope, her first Free Time Event with Shuichi reveals that she made an "Auto-Puncher that Punches You for Telling Terrible Dirty Jokes." Once she makes a dirty joke, the invention does its job.

* AggressiveSubmissive: In both senses. Miu constantly boasts about her accomplishments and appearance, barrages the other characters with insults, and is perhaps the single most vulgar character in the entire series. She also enjoys acting as TheTease to Shuichi, Keebo, and... generally everyone else. Despite this, [[PaperTiger her aggressive façade cracks very easily and covers up a meeker and submissive side]]. She's shown to get off when degraded, like being called a "cum dumpster" by [[TheGadfly Kokichi]], and in ''Love Across the Universe'', she will beg for mercy when Shuichi suggests sword-fighting with movie posters, believing that he is punishing her for making him angry. In her Love Suite Event, Miu drops her loudmouthed act and gives Shuichi permission to have his way with her, expecting him to make a move on her. In ''Ultimate Summer Camp'', Miu gets angry at Mikan, who then tells her that she is free to write mean words to her. At that moment, Miu awkwardly declines and says that she prefers ''being written on'', suggesting that she prefers being submissive. Unlike most examples of this trope, there are still multiple implications that Miu genuinely enjoys being in positions of power, and her Love Hotel event has her taking charge at the end. When she [[GRatedSex performs maintenance on Keebo]], Miu acts assertively in a more flirty manner.
** This gets lampshaded by Fuyuhiko in ''Ultimate Summer Camp'' after Miu orders Kirumi to massage her, do maintenance on the Monokubs, and do a system check in the outside world. Kirumi—note that she is a maid, a ''subservient'' role—agrees to do the first two tasks but firmly orders Miu to do the third one herself, leading Miu to quickly back down and comply.

* UnreliableNarrator:
** Invoked in Chapter 4 when Kokichi suggests that her motive for killing him so she could escape and save the world was just a lie. However, nothing else disproves her motive, and she seems deadly serious when telling Kokichi about it.

* BunnyEarsLawyer: She might be an oddball, but her talent as an inventor does come in handy, and her inventions helped the group on several occasions, like during Chapter 5.
* ButtMonkey: Boy, is she ever in the ''Ultimate Talent Development Plan''

* ParalyzingFearOfSexuality: Surprisingly, despite her perverted antics and tendency to act as TheTease to just about everyone, Miu gets incredibly nervous and uncomfortable whenever someone makes (what she perceives to be) an advance, insisting on a romantic gesture first. Likewise, in her Love Suite Event with Shuichi, Miu very quickly drops her LargeHam front and nervously him that he can have his way with her. This very strongly implies that Miu has never had sex before, nor has she ever been in a serious opportunity thereof.

* HatedByAll: Everyone despises her for [[{{Jerkass}} good reason]]. It’s gotten to the point that once she was killed and revealed she attempted to get everyone executed, They lose what little respect that have her. This also applies when Kokichi gets killed.

* TheBully: Ultimately less of one than Kokichi, given her [[NoSocialSkills terrible social skills]] and [[InnocentlyInsensitive tendency to act in terrible taste without realizing it]], but even so, she is still more than willing to aggressively insult anyone and anything that crosses her path, in particular targeting the less confrontational students like Shuichi and Himiko, usually in the form of VirginShaming or giving an [[TheNicknamer immature and (usually) obscene nickname]]. Not to mention that, at her worst, she can make very abusive insults, Ironically, she is the main target of Kokichi (though he might be aware of Miu's masochism kink and just bullies her to indulge her), making her both this trope and a target.
* BunnyEarsLawyer: She might be an oddball, but her talent as an inventor does come in handy, and her inventions helped the group on several occasions, like during Chapter 5.
* ButtMonkey: Boy, is she ever in the ''Ultimate Talent Development Plan''.

* DoubleStandardRapeFemaleOnMale: The entire scene in which Miu does maintenance on Keebo, and in a ''very'' suggestive matter. Miu was clearly having too much fun:
-->'''Miu:''' ''[giggling]'' So THAT'S the sound you make when I touch that spot. Good to know.

* FatalFlaw: Cowardice and Abusiveness. Miu's constanly insults to her classmates as all we as her paranoia and fear that she will be the next target in the Killing Game grows in intensity as the story goes on and, when the flashback light used in Chapter Four indicates the world outside is just as terrifying as the killing game and could be in greater need of her help, she decides she'd rather win the game to escape by herself despite knowing it'd kill everyone else. Unfortunately, had Miu chosen to work with Shuichi and the group, she could have left with her life, considering how important her inventions prove to be in Chapter Five.

* {{Jerkass}}: Miu [[HateSink constantly insults everyone]] [[BullyBrutality she deems beneath her,]] with the flimsiest excuses possible, [[LethallyStupid Is dangerously stupid in the murder cases]],
* KickTheDog: Anytime she appears on-screen or even talk, she just abuses her classmates for little to no-reason.

* TheLadette: Miu is loud, extremely vulgar, and obnoxious, [[LadySwearsALot swears or insults someone almost every time she opens her mouth]], is [[WrenchWench skilled with mechanics and machinery]], and refers to herself with the very masculine (and very arrogant) "ore-sama" in the original Japanese, therefore making her one of the least feminine girls in the entire franchise.
* LadySwearsALot: Probably the most foul-mouthed character in ''V3'', if not in the entire series as well; only Genocide Jack comes close to swearing as often. And Kokichi, Monokid, and Monsouke are the male versions of her. Even the past characters known for constantly swearing, Mondo and Fuyuhiko, are not as foul-mouthed as Miu is.

* NWordPrivileges: Miu says that "a robot ain't people, jack." Keebo, who [[FantasticRacism would normally interject and accuse the person of robophobia, lets her remark slide.]]

* TheNicknamer: Often refers to her classmates with (usually) very abusive nicknames,

* {{Robosexual}}: Naturally, one would expect the Ultimate Inventor to be fascinated with a RidiculouslyHumanRobot like Keebo. It's just that her interests are [[RapeIsASpecialKindOfEvil not exactly academic]], much to Shuichi's [[BrainBleach chagrin]]...

* SpeakIllOfTheDead: One of Miu's less sympathetic and more annoying qualities is a tendency to mock the deaths of her classmates, saying that its better to find Rantaro's body than a dirty pile of rags, [[FantasticRacism and even makes racist xenophobic insults about Angie.]] She also refers to all of the students, dead and alive, as pieces of shit after Korekiyo's execution. Ironically, she was the first person to die after that, and Kokichi does this to her after she dies.

* BeneathTheMask: She is shy and submissive beneath her rude, LargeHam persona and quickly backs off when confronted. It is also suggested that she uses sex and vulgarity in an attempt to cover up her [[InferioritySuperiorityComplex insecurities]], and her indignant reaction to being virgin-shamed (despite virgin-shaming her classmates regularly) and awkwardness in her Love Suite Event imply that Miu might be a virgin herself. Miu also seems more interested in actual love than just sex anyway, as suggested by her Free Time Events and Love Suite Event. Keebo, who has stored all of Miu's deeds in his memory bank, reports that Miu also has a natural innocence that she conceals with her loudmouthed persona.

* BirdsOfAFeather: A platonic version with Teruteru, as they both are massive perverts.
* BlackComedy: A veritable fountain of this, especially when she bakes Shuichi a pie with her hair, cookies with her fingernails, and chocolates with her blood, ''all because she wants the person she likes to eat her''.

* TheBully: Ultimately less of one than Kokichi, given her [[NoSocialSkills terrible social skills]] and [[InnocentlyInsensitive tendency to act in terrible taste without realizing it]], but even so, she is still more than willing to aggressively insult anyone and anything that crosses her path, in particular targeting the less confrontational students like Shuichi and Himiko, usually in the form of VirginShaming or giving an [[TheNicknamer immature and (usually) obscene nickname]]. Not to mention that, at her worst, she can make very harsh insults, like calling Kokichi a "lyin' little abortion". Ironically, she is the main target of Kokichi (though he might be aware of Miu's masochism kink and just bullies her to indulge her), making her both this trope and a target.

* {{Cloudcuckoolander}}: Miu tends to have some very ''odd'' thought processes and ideas. For example, she is convinced that she's an augmented human after surviving a near-fatal car accident ''and then tries to dismantle herself'' to prove it. One of her inventions helps you eat while you're sleeping, and a lot of her other inventions are simply as perverted as she is. In one of her ''Love Across the Universe'' date events, Shuichi can suggest that he and Miu get some fresh air, and Miu will get the idea of making an air purifier that makes the air taste like her ''musk''. Shuichi even notes that Miu expresses her love in strange ways. After falling in love with him, Miu bakes him a pie with her hair and mentions that she made cookies with her fingernails and chocolates with her blood, saying that she wants the person she likes to eat her. When Shuichi declines for hygienic purposes, Miu decides to give him her panties and insists on him going on a date with her.
* TheCloudcuckoolanderWasRight: Despite her strange way of thinking, Miu actually gets the culprit right in every single trial she participates in, often very early on to boot; she just doesn't have the deductive skills to answer the how and why. See also RightForTheWrongReasons.
** To wit:
--->'''Trial 1 ー''' "Then Monokuma's the culprit! Duh-doy! Cuz this whole class trial was his idea!" ''*True in that Tsumugi works for Monokuma.''\\
'''Trial 2 ー''' "I don't care if it was five seconds! It's way too suspicious you were alone in the gym! I think the cleaning lady here is the culprit!"\\
'''Trial 3 ー''' "The culprit used a katana to kill Angie! And the katana was found in Kiyo's research lab!"\\
'''& ー''' "The person who lifted the white sheet is the culprit... And that's none other than Kiyo!"
** This is exemplified in her Rebuttal Showdown, as she argues Kiyo killed Tenko, though Shuichi cuts through the details she got wrong. Surprisingly, Miu starts at an advantage, meaning the students were actually leaning ''toward'' her assessment.

* ComicallyMissingThePoint:
** Prone to happen with Miu, usually in the form of her thinking that a clearly innocuous statement has sexual undertones. To name one example from ''Ultimate Talent Development Plan'', Miu plans to remodel Teruteru into a literal cooking machine, to his horror. Hiyoko, who approves of it so that Teruteru would not say anything again, suggests that Miu sew her mouth shut too, but Miu has this to say:
--->'''Miu:''' I...I've never tried that kinda kink play before... Maybe just a little...
** For a non-sexual example, Shuichi can suggest that they burn the gym to the ground in ''Love Across the Universe''. Miu then assumes that he wants to use her "Instaburn" invention, which is, as she describes it, "for burning up social media accounts owned by ugly bitches who take too many selfies." That invention, however, will not cause burning anywhere else.

* EveryoneHasStandards:
** Miu may be very perverted and open about her kinks, but even she finds some things too much for her. For example, she was disgusted by Korekiyo's BrotherSisterIncest and that he murdered Angie and Tenko over it. She even thinks Toko takes things further than she does, finding her fantasy about being Byakuya's doormat and having him wipe his feet on her too disturbing to talk about in public. Amusingly, this can overlap with HypocriticalHumor, as Toko claims that Miu gets turned on by even weirder fantasies than that.
** Despite her teasing and insulting Kaede, Miu is visibly distraught after she is executed.
** She always talks about people bowing before her after Kaede and Shuichi did so, but even when someone does so, she's visibly uncomfortable.
** In ''Love Across the Universe'', Miu is absolutely '''terrified''' of the thought of someone SlippingAMickey into her drink and then raping her.
** Miu gets nervous when someone makes a sexual advance on her and insists on going on a date first, suggesting that for all her slutty behavior, Miu is actually much more romantic than she lets on.
** In ''Ultimate Summer Camp'', she's creeped out by how into having control over injured people Mikan is.
* FatalFlaw: Cowardice. Miu's paranoia and fear that she will be the next target in the Killing Game grows in intensity as the story goes on and, when the flashback light used in Chapter Four indicates the world outside is just as terrifying as the killing game and could be in greater need of her help, she decides she'd rather win the game to escape by herself despite knowing it'd kill everyone else. Unfortunately, had Miu chosen to work with Shuichi and the group, she could have left with her life, considering how important her inventions prove to be in Chapter Five.

* GRatedSex: The entire scene in which Miu does maintenance on Keebo, and in a ''very'' suggestive matter. Miu was clearly having too much fun:
-->'''Miu:''' ''[giggling]'' So THAT'S the sound you make when I touch that spot. Good to know.

* GyaruGirl: It can be reasonably inferred that Miu is one; for one thing, her pre-game outfit has her wearing platform shoes and a very short skirt, which is common with kogals. This is carried over to her main outfit.

* InnocentlyInsensitive: Despite her rude, loudmouthed behavior, Miu often seems genuinely surprised when people get annoyed at her blunt ways and crude sense of humor. Kaede notes that Miu's intent isn't usually (key word being "usually") malicious; she just does not seem to realize that she is acting in terrible taste, and she tends to sound insulting even when she tries to be nice. For example, in the ''Ultimate Talent Development Plan'' bonus mode, she is shocked that Gundham gets mad at her for calling him "dogfucker" as a greeting. Also, her attempt to compliment Kazuichi's outfit baffles the latter as she also says that people would pay less attention to his face if he did not slouch.

* JerkWithAHeartOfGold:
** Miu quickly establishes her character by insulting Kaede's breast size, [[HypocriticalHumor accusing Shuichi of being a pervert]] just because he [[InsaneTrollLogic wears a hat]], and generally being very prickly; she spends most of the game boasting about her looks, talent, and intelligence. Despite all this, she can show some form of compassion when things become more serious; she becomes very good friends with Keebo, is very upset over Kaede's death, and repeatedly apologizes to Kokichi as she attempts to kill him. When Miu dies, Shuichi lampshades this before the fourth trial, having this to say:
--->'''Shuichi:''' Miu Iruma, the Ultimate Inventor. She may have given us a lot of trouble, but we all miss her. It's a tragedy, after all. She helped me and Kaede with those cameras, gave Keebo extra functions. In the end, she had done a lot for us...
** On another note, her Free Time Events with Kaede and Shuichi and her Love Suite Event reveal that Miu is a girl of [[InferioritySuperiorityComplex many insecurities]] who genuinely wants people to like her; what prevents this is her social ineptitude, namely her tendency to act in terrible taste by saying anything and everything that comes to mind, not helped by her FriendlessBackground. As the two spend enough time with her, Miu warms up to them and makes it clear that she enjoys their company; she just tends to sound insulting even when she tries to be nice. When Kaede tries to teach Miu how to talk to other people normally, Miu becomes grateful and develops a ''slightly'' better understanding, though she will make another joke about Kaede being "flat." Likewise, Shuichi, one of her frequent VirginShaming targets, assures an insecure Miu that her inventions are incredible (he finds a lot of them absurd to the point of being impractical). With that, she decides to treat him "real good" from there, though she will still call him a virgin, and she eventually falls in love with him. She also gives him one of her inventions for free, highlighting her more generous side.

* JerkassHasAPoint:
** Her motives for trying to kill Kokichi are altruistic, saying the world needs her and her inventions. Given just how useful her inventions prove to be in the game, she wasn't entirely wrong for thinking this.
** She's also correct in protesting that Angie and her cult have no right to tell the other students they can't go out at night in Chapter Three, especially since they don't follow this rule.
** {{Lampshaded}} by Kazuichi in ''Ultimate Summer Camp'' when Monomi unsuccessfully begs Miu to try to get her to her original form. He points out that Monomi only has vague descriptions of her original form, which is not a lot to work on, and Miu, knowing nothing of the sort, needs more concrete visual aids, like [[BreadEggsMilkSquick photographs, blueprints, or porn magazines]]. A combination of this and Miu being... Miu leads her to say this:
--->'''Miu:''' So you were a pink, frilly rabbit that looked like sexy lingerie for a guy to bust on, or some shit?
* KnowNothingKnowItAll: While she is a brilliant inventor, Miu is not nearly as skilled at detective work and often needs others to correct her deductions.
* {{Kodomomuke}}: Miu's report card shows that she likes watching this. This ties in nicely with both her childish behavior (her juvenile insults and nicknames) and her fondness for children (her tenderness towards her "son" Monotaro).

* TheLadette: Miu is loud, extremely vulgar, and obnoxious, [[LadySwearsALot swears or insults someone almost every time she opens her mouth]], is [[WrenchWench skilled with mechanics and machinery]], and refers to herself with the very masculine (and very arrogant) "ore-sama" in the original Japanese, therefore making her one of the least feminine girls in the entire franchise even with her ShrinkingViolet moments.
* LadySwearsALot: Probably the most foul-mouthed character in ''V3'', if not in the entire series as well; only Genocide Jack comes close to swearing as often. Even the past characters known for constantly swearing, Mondo and Fuyuhiko, are not as foul-mouthed as Miu is.
* LargeHam: She's boisterous and likes talking big. On the other hand, give her any sign of aggression, and she'll fold back. Creator/WendeeLee was clearly having the time of her life voicing Miu.

* NWordPrivileges: Miu says that "a robot ain't people, jack." Keebo, who would normally interject and accuse the person of robophobia, lets her remark slide.

* TheNicknamer: Often refers to her classmates with (usually) insulting nicknames, including:
** "Kaediot" and "Guy-a-Day" for Kaede ("Bakamatsu"[[labelnote:meaning]]from ''UsefulNotes/{{baka}}'' (idiot) and ''Akamatsu''[[/labelnote]] and "Ikamatsu"[[labelnote:meaning]]from ''ika'' (squid) and ''Akamatsu''[[/labelnote]] in the Japanese version).
** "Poo-ichi", "Sherlock Homo", Kaede's "Beta Boytoy" for Shuichi ("Saohara"[[labelnote:meaning]]from ''sao'' ("rod", but more colloquially "penis") and ''Saihara''[[/labelnote]], "Hamehara"[[labelnote:meaning]]from ''hame'' (sexual intercourse) and ''Saihara''[[/labelnote]], "Dasaihara"[[labelnote:meaning]]from ''dasai'' (uncool) and ''Saihara''[[/labelnote]], "Munougehara"[[labelnote:meaning]]from ''munou'' (incompetent) and ''Saihara''[[/labelnote]], "Shobohara"[[labelnote:meaning]]from ''shoboi'' (gloomy) and ''Saihara''[[/labelnote]] and "Kusaihara"[[labelnote:meaning]]from ''kusai'' (smelly) and ''Saihara''[[/labelnote]] on the Japanese version).
** Variations of "Donkey-Lips" and "Titless" for Himiko.
** "Miss Andry," "Cunt-Fu," and "Ten-crotch" for Tenko ("Chabanegokiburi"[[labelnote:meaning]]lit. ''German cockroach''[[/labelnote]] in the Japanese version).
** "Cockichi" for Kokichi.
** "Bobblehead" and "kooky bitch" for Angie.
** "Creepshow" for Korekiyo.
** "Tarzan" for Gonta.
** "Low rider" for Ryoma.
** "Plain Jane" and "Four-Eyes" for Tsumugi. %%My memory is terrible so please feel free to add more of these...lovely nicknames.
** "Slowko," "mopey masochist mophead," and "Broke-ko" for Toko.
** "Fuckface" and "Bigcockohyeah" for Byakuya.
** "Dogfucker" for Gundham.
** "Pig-face" for Teruteru.
** "Nasty warthog," "Christmas ham," and "sad-lookin' sow" for Mikan.
** "[[Franchise/WinnieThePooh Winnie the Piece of Shit]]" for Monokuma.
** "Hard head" for Kiyotaka.
** "Hell on Wheels" for Mondo.
** "[[AscendedMeme Banana gremlin]]" for Hiyoko.
** "Smooth brain" for Akane.
** "Vermin" and "farts and crafts kid" for Jataro.
** "Pinkie" for Kotoko.
** "Cherry boy," "grease-monkey," and "Miu wannabe" for Kazuichi.
*** She herself gets referred to as "Bitchlet" and, perhaps memorably, "Cum Dumpster" by [[LovingBully Kokichi]] in-game. She gets called an "Enchantress" by Gundham, "Blonde Bitch" by Toko, "Pig Woman" by Hiyoko, and "Disgusting Woman" by Byakuya in the ''Ultimate Talent Development Plan'' bonus mode.

* {{Robosexual}}: Naturally, one would expect the Ultimate Inventor to be fascinated with a RidiculouslyHumanRobot like Keebo. It's just that her interests are not exactly academic, much to Shuichi's [[BrainBleach chagrin]]...

* SadClown: Miu has several deep-seated issues behind her loudmouthed façade, and her [[InferioritySuperiorityComplex insecurities]] eventually lead her to take drastic measures in an attempt to escape the killing game. Her insecurities are explored a bit in her Love Suite Event, where it reveals that Miu is desperately lonely and has major abandonment issues.

* ShipperOnDeck: In her own [[LargeHam Miu]] way, she seems into the idea of Shuichi and Kaede being a couple. When she sees the two together, she exclaims: "A fuckin' skank and a hat-wearing pervert - you two are made for each other!" in the first chapter and even jokingly suggests that they get condoms from the warehouse.
* ShooOutTheClowns: With her lewd personality being mostly PlayedForLaughs, the story became a lot more serious the second she ended up dying, with it being discovered that [[GentleGiant Gonta]] killed her. Let's just leave it at that.
* ShrinkingViolet: It may not look like it at first, but this is what Miu is in reality. She is a shy and submissive girl with [[InferioritySuperiorityComplex many insecurities]], and she tries to cover them up by acting loudmouthed and perverted. She is also very sensitive and gets startled easily whenever people shout at her. Her shy side is best shown in her Love Suite Event with Shuichi, especially when she nervously explains why she wants to thank Shuichi by permitting him to have his way with her. In the art book, her Japanese voice actress describes Miu as a fundamentally adorable girl who happens to have very extreme sides.
-->'''Miu:''' ... D-Don't laugh...okay?\\
'''Shuichi:''' Alright. I won't laugh.\\
'''Miu:''' You won't...shout at me?\\
'''Shuichi:''' Of course I won't. Don't worry.

* SourOutsideSadInside: Miu is very abrasive and prickly, constantly insulting her classmates, getting angry at them if they waste her time, and generally being a nuisance to everyone. Underneath all of Miu's craziness and antics, however, is [[InferioritySuperiorityComplex a lot of insecurities]]. She wants people to like her because of her beauty and genius, but she quickly falls apart when these attempts fail. She does not trust her classmates enough to work with them, and she ends up attempting to kill Kokichi to escape the Killing Game. Her Love Suite Event also reveals that Miu is a very lonely girl with severe abandonment issues. She wants someone who can always stay by her side, but her abandonment issues led her to believe that a BabyTrap plan is the only sure way that her loved one will stay with her. And, considering her FriendlessBackground, she will immediately [[BecauseYouWereNiceToMe fall in love with anyone who shows her even a tiny amount of care and affection]]. Yeah. Miu is a hot mess.

* SpeakIllOfTheDead: One of Miu's less sympathetic qualities is a tendency to mock the deaths of her classmates, saying that its better to find Rantaro's body than a dirty pile of rags and referring to Tenko as "Cunt Fu" as her corpse is laying right in front of her. She also refers to all of the students, dead and alive, as pieces of shit after Korekiyo's execution. Ironically, she was the first person to die after that, and Kokichi does this to her after she dies. Though, Miu being... [[NoSocialSkills Miu]], this was more likely than not another poor coping mechanism as she is notably shaken by the deaths around her, especially Kaede's.

* WrenchWench: She is a skilled enough mechanic to perform maintenance on Keebo.
* {{Yandere}}: PlayedForLaughs in her last free time event with Shuichi. Miu tries to give him a pie ''with her hair in it''. She also baked cookies with '''her fingernails''' and made chocolates with '''her blood''' as ingredients, saying that she wants the person she loves to eat a little piece of her. Also, her Love Suite Event consists of her attempting to seduce Shuichi into impregnating her so that he would remain by her side forever, Miu's abandonment issues aside.
-->'''Miu:''' C'mon, please...? I...want you... I...need you inside me, Shuichi. Okay? That's okay, right? Please?
* YourMindMakesItReal: Miu is killed in a Virtual Reality world, rendering her dead in real life.

!Miu Iruma
!!Warning: Unmarked {{spoiler}}s for ''VisualNovel/DanganronpaV3KillingHarmony''
!!! '''Ultimate Inventor'''

Wanting to get away from the chaos of the killing game, she modifies the academy's Neo World Program to allow the cast to live in Virtual Reality where the risk of death is minimal. However, it is later revealed that she intended to use the program to kill Kokichi Oma in an unsolvable murder. Instead, she is the victim of Chapter 4, strangled to death within Virtual Reality by Gonta Gokuhara, who Kokichi manipulated into performing a mercy kill.

* TheBully: Ultimately less of one than Kokichi, given her [[NoSocialSkills terrible social skills]] and [[InnocentlyInsensitive tendency to act in terrible taste without realizing it]], but even so, she is still more than willing to aggressively insult anyone and anything that crosses her path, in particular targeting the less confrontational students like Shuichi and Himiko, usually in the form of VirginShaming or giving an [[TheNicknamer immature and (usually) obscene nickname]]. Ironically, she is the main target of Kokichi (though he might be aware of Miu's masochism kink and just bullies her to indulge her), making her both this trope and a target.

* FriendlessBackground: Her second Free Time Event with Kaede reveals that Miu didn't have anyone she could call a friend before becoming a part of the killing game, which Miu is embarrassed to admit. This is evidently a sore spot for her since, in ''Ultimate Talent Development Plan'', Miu gets dispirited when Toko tells her that her vulgarity drives people away. Her Love Suite Event also implies that her friendless background might be, at least in part, why she acts so loud and obsessed with sex, and that her loneliness is exacerbated by her severe abandonment issues.

* LoveEpiphany: PlayedForLaughs in her fourth Free Time Event with Shuichi. Miu reacts very wildly as she attempts to process that she's falling in love with Shuichi, like stripping herself and trying to get Shuichi to do the same and trying really hard to deny that she is in love with him... even though she eventually admits it anyway.* LuminescentBlush: Shown in a couple of her sprites, especially when she is feeling [[https://vignette.wikia.nocookie.net/danganronpa/images/b/b6/Danganronpa_V3_Miu_Iruma_Halfbody_Sprite_%2826%29.png/ nervous]] or [[https://vignette.wikia.nocookie.net/danganronpa/images/7/73/Danganronpa_V3_Miu_Iruma_Halfbody_Sprite_%2831%29.png/ aroused]].

* TooKinkyToTorture: PlayedForLaughs. Miu has a masochism kink. She is open about being into waxplay and likes it when she gets degraded, as [[HoistByHisOwnPetard Hiyoko learned the hard way]] in the ''Ultimate Talent Development Plan'' bonus mode. Hilariously, Miu finds Toko ''too'' masochistic for her, as she finds her fantasies about being Byakuya's doormat unnerving (though Toko claims it is HypocriticalHumor on Miu's part).* {{Tsundere}}: An unusual take on the Harsh type of tsundere. Speaking very broadly, Miu is a very loud, abrasive, and crude girl who makes sex jokes and insults her classmates regularly. Her abrasive side, however, is incredibly fragile, and underneath this is a desperately lonely and meek girl who has NoSocialSkills and simply wants people to like her and admire her genius. Keebo says that Miu hid a natural innocence, and Miu herself admits to Shuichi in her Love Suite Event that her loudmouthed persona is an act. Miu will warm up to Kaede and Shuichi if they complete her Free Time Events to the point where she really likes spending time with them, though she will still insult them every now and then. In Kaede's case, Miu will develop a ''slightly'' better understanding of how to speak like a normal person and thank her for trying to teach her, though not without making another joke about Kaede being "flat." For Shuichi, one of her frequent virgin-shaming targets, Miu will fall in love with him and get him to go on a date with her.

* DitzyGenius: Brilliant as she may be regarding machines and inventions, her intelligence seems to be entirely specialized in those fields. Aside from her eccentricities, she's more prone to making irrational leaps of logic than everyone else when participating in a trial.* DropTheHammer: Miu smuggles a hammer into the Virtual World to kill Kokichi, but Gonta gets the drop on her before she can use it.

* EstablishingCharacterMoment: When she first meets Kaede and Shuichi, Miu insults them and arrogantly introduces herself, and when Kaede says she hasn't heard of her, Miu mentions she invented and sold off contact-lenses eyedrops, viewing that invention as a failure. She then says she's going to see if she can find some drugs so she can "trip [her] fuckin' balls off" and forget about being trapped at the academy. When Kaede scolds her for this, she reverts to her meek personality, apologizes, and pleads with Kaede not to be angry with her.* ExpressiveHair: Her hair fluctuates from lively when excited or agitated to wrinkly when frightened or surprised.

* FriendlessBackground: Her second Free Time Event with Kaede reveals that Miu didn't have anyone she could call a friend before becoming a part of the killing game, which Miu is embarrassed to admit. This is evidently a sore spot for her since, in ''Ultimate Talent Development Plan'', Miu gets dispirited when Toko tells her that her vulgarity drives people away. Her Love Suite Event also implies that her friendless background might be, at least in part, why she acts so loud and obsessed with sex.

** When Shuichi spends time with the other students, he says, "X and I grew a little closer today." On the other hand, when he spends time with Miu, he says, "I somehow ended up growing a little closer to Miu..." as if he cannot believe he is growing close to someone like her. It's worth noting that not even ''Kokichi'', another similarly disliked student, gets this dubious honor.

* HatesBeingAlone: Miu is a lonely girl at heart, and it is strongly suggested that she acts all loud and slutty in an attempt to cover this up. Her FriendlessBackground is evidently a sore spot for her as she is embarrassed to admit it when Kaede confronts her about it in her second Free Time Event with her, and in ''Ultimate Talent Development Plan'', she quickly gets dispirited when Toko points out that people cannot put up with her vulgarities, perpetuating her lack of friends. ''Ultimate Summer Camp'' has Miu telling Kaede that she is bewildered that Toko, whom she claims is an even bigger pervert than she, has a friend in Komaru, to which Kaede replies that Toko is much less abrasive. Later, Kaede and Miu arrange a sleepover, and Miu specifically tells Kaede not to stand her up and leave her to sleep alone. Her Love Suite Event also suggests that Miu has severe abandonment issues, making her loneliness worse. In the middle of an otherwise pleasant ChildhoodFriendRomance fantasy, Miu tries to invoke a BabyTrap plan, believing that it is the only sure way to keep her beloved by her side and prevent him from abandoning her.

* InnocentlyInsensitive: Despite her rude, loudmouthed behavior, Miu often seems genuinely surprised when people get annoyed at her blunt ways and crude sense of humor. Kaede notes that Miu's intent isn't usually (key word being "usually") malicious; she just does not seem to realize that she is acting in terrible taste, and she tends to sound insulting even when she tries to be nice. For example, in the ''Ultimate Talent Development Plan'' bonus mode, she is shocked that Gundham gets mad at her for calling him "dogfucker" as a greeting. Also, her attempt to compliment Kazuichi's outfit baffles the latter as she says that people would pay less attention to his face if he did not slouch.

** {{Lampshaded}} by Kazuichi in ''Ultimate Summer Camp'' when Monomi unsuccessfully begs Miu to try to get her to her original form. He points out that Monomi only has vague descriptions of her original form, which is not a lot to work on, and Miu, knowing nothing of Monomi's original form, needs more concrete visual aids, like [[BreadEggsMilkSquick photographs, blueprints, or porn magazines]]. A combination of this and Miu being... Miu leads her to say this:

*** She herself gets referred to as "Bitchlet" and, perhaps memorably, "Cum Dumpster" by [[LovingBully Kokichi]] in-game. She gets called an "Enchantress" by Gundham, "Blonde Bitch" by Toko, "Pig Woman" by Hiyoko, and "Disgusting Woman" by Byakuya in the ''Ultimate Talent Development Plan'' bonus mode.* NoSocialSkills: Her second Free Time Event with Kaede reveals that Miu lacks the social skills to properly filter herself and just says whatever comes to mind, resulting in her insensitive and vulgar manner of speaking (though how much this excuses her tendency to indiscriminately harass her classmates, especially when she does things like attempting to grope Kaede's breasts or using slurs like "'tard" and "homo", is up for debate). Kaede tries to teach Miu how to properly speak with people, especially those that Miu wants to be friends with, but gets exhausted and believes that she used a year's worth of patience (granted, Miu is grateful for that and develops a ''slightly'' better understanding on how to talk like a normal person, but still). Even when she manages to avoid sounding insulting, Miu is utterly lacking in social graces. In her Free Time Events with Shuichi, Miu tells him to follow her to her lab and then sets out without waiting for a response from him. After she falls in love with Shuichi, Miu expresses her affection by baking some sweets with her "hidden ingredients" because she wants the person she likes to eat her. When Shuichi declines for hygienic purposes, Miu decides to give him her panties, telling him that he has earned the right to date her.

{{Jerkass}}: Miu constantly abuses everyone she deems beneath him, and sexual assaults Kaede and Shuichi numerous times, and is implied to have RAPED Keebo while performing the upgrades on him.* KarmicDeath:
