"No, I'm Prairie. Perfect Blitz is dead.”
The young girl who wakes up without any memories other than her name and her age. She gained the ability to bypass the effects of flashback lights due to a candy she ate when she first woke up. Although she doesn’t know her Ultimate Talent at first, Prairie learns later that she’s the acclaimed rock climbing celebrity “Perfect Blitz”, known for free-soloing when climbing thousands of feet up rock faces. She doesn’t act like Perfect Blitz at first - aggressive, hubristic, narcissistic, and outspoken - but her roots start to show as time progresses in the Killing Game.
- Affectionate Nickname: Kokichi has a slew of this, his favorites being “Prairie Dog” and “Mousey-Mouse”.
- All of the Other Reindeer: Prairie’s status as someone who clearly holds more knowledge about the killing game than the rest of the students as well as her previous reputation as a celebrity establishes that gap between her and the other students. It’s also implied during the flashback dream in chapter 2.11 that her past before she lost her memories also had the same situation.
- Apologizes a Lot: Prairie has a habit of doing this especially before she realizes she’s Perfect Blitz.
- Bad Liar: Kokichi points out that Prairie tends to close in on herself, bite her lip when she’s thinking of a lie, and blush after she lies.
- Badass Adorable: Most of the students don’t expect a cute girl like Prairie to actually be the one who gets thrown around by Exisals and physically hurt the most when it comes to the fight against Monokuma.
- Because You Were Nice to Me: The reason why Prairie feels comfortable with Rantaro from the very moment they first met.
- Berserk Button: Do not call Prairie “moe”.
- Blessed with Suck: Her intuition gives her a “cheat sheet” that gives her information when she wills it or perform skills she’s not familiar with, but using it too much causes a rebound that will give her a nosebleed or bleed from most of her orifices depending on the intensity she’s using it. It gets noticeably bad and bloody when a flashback light gets used Post-Pregame.
- Break the Cutie: What Monokuma is attempting to do against Prairie. It’s debatable whether it’s working or not mentally, but she is the physically most beaten down out of all the students to an alarming extent.
- Butt-Monkey: The Monokubs enjoy tormenting Prairie the moment they learn that she’s resistant against the flashback lights. Out of the five bears, Monophanie might be considered the worst, especially when she wrecks the dorm plate of her room, puts gum on Prairie’s hair, and messes up Rantaro’s attempts to get Prairie out of jealousy. There’s also the usual Monokubs harassment when they’re in their exisals.
- Kokichi also enjoys doing this to Prairie, though he is debatably not as mean-spirited as the Monokubs.
- The first trial takes it Up to Eleven where Prairie is embarrassed by the others (most notably Kokichi) in Chapter 3.18 that some of the students find her embarrassment as a distraction for the current-hand topic of finding the murderer.
- Cannot Talk to Men: Prairie’s clinical embarrassment towards people she finds attractive (which is basically all the male students in the current killing game, as she states) is the first thing we learn about her in the first chapter.
- Catchphrase: It’s not used as often in the latest chapters but when Prairie is flustered by someone swearing, she’d say: “Profane…”
- Cute Bruiser: Deconstructed. The readers are led to believe that Prairie is pretty helpless at first, but her strength becomes apparent as the killing game goes on.
- The Cutie: Prairie’s previous personality, Perfect Blitz, is a subversion of this. She was known to get into multiple scandals and gained a reputation as the “Perfect Bitch”. It’s Deconstructed with the current Prairie as she’s seen as this at first, but breaks the conventions of the trope more and more as the fic goes on.
- Determinator: Even Monokuma notes that Prairie’s a trooper when it comes down to it. The reason why Rantaro doesn’t want Prairie to go into the Death Road of Despair is because he knows she’s going to risk her life to get through it.
- Does Not Like Spam: Prairie’s quarrel with Kokichi in the middle of the first trial has her proclaiming that she hates Kokichi “more than she hates cauliflower”.
- Easily Embarrassed Youngster: Exaggerated. Prairie’s embarrassment (especially towards boys) can even make her faint for a moment.
- Foil: To Angie, or that seems to be what’s implied. While Angie is known to be bright and cheery but clearly hiding her plans behind her smile, Prairie is pretty straight forward on what she intends to do as long as it’s not restricted by Monokuma. Though the development hasn’t happened yet in the fic, it’s clear that Angie is trying to push towards the united cohabitation she intends to enforce with the student council, while Prairie is clearly impatient by everyone else wasting a single minute not figuring out a way out of the academy.
- Forgets to Eat: Shuichi explains to Prairie that Perfect Blitz had a history of skipping meals to the point of getting herself sick as a form of an eating disorder in Chapter 3.13.
- Good Is Not Soft: Justified. Other students might think she starts off soft, but the experience she’s gained in the Killing Game has hardened her outlook. Who can blame her, when Monokuma targets most of his harassment towards Prairie?
- Hair-Trigger Temper: One of the things Perfect Blitz was known for, although it might not be obvious when it comes to Prairie herself. Especially in the presence of a certain purple-haired leech, though other people aren’t immune to her ire. As of the last few chapters of Part 3, she promises Rantaro that she’s willing to work on it.
- Huge Guy, Tiny Girl: The tiny girl to Rantaro’s huge guy. She even remarks a few times on how much of a “tower” Rantaro is even though there are other characters taller than him.
- Identity Amnesia: Prairie has no recollection of her life as Perfect Blitz, although her personality starts to converge with the one before she lost her memories.
- Loose Lips: It isn’t common that Prairie would remark on how attractive Rantaro is to his face on accident (especially when she’s irritated) but when it does happen, it’s a one way ticket into an embarrassed Prairie.
- Meaningful Rename: Not in the obvious way, but the last flashback light in Part 1 almost erases the entirety of Prairie’s memories to the point where she almost mistakes her name as “Prairie Marvel”. The only reason she managed to keep her old memories beforehand is because she kept hold to the knowledge of her actual (?) name and her age.
- Mood-Swinger: Since the reader is wearing Prairie’s shoes most of the time, the process of her “mood-swings” are actually pretty understandable. Still, the other students aren’t privy to how Prairie’s thought process works and it’s not uncommon for them to bring it up.
-
Moe: She heard Shuichi call her this during chapter 3.2 while hiding, which results in her throwing a small stone on his head in anger. She gets called out by Kokichi for using her cuteness to her advantage against the others unknowingly. - Ms. Exposition: Deconstructed. Prairie has additional knowledge in the killing game that would be advantageous for the other students to know. It’s just that Monokuma has enforced a rule that she can’t tell the other students about it less she risks being punished, he even painted a golden target on her back so that she becomes a desirable target for killing.
- The Napoleon: Her presence dwarfs Himiko in terms of height (by one inch), standing at the proud height of 147 cm/4’10”.
- Nosebleed: Justified. See Power at a Price for more elaboration.
- Power at a Price: The chocolate Prairie eats in the first loop prevents her from being affected by flashback lights and “intuition” that allows her to pull information about anything or do certain feats that she wouldn’t have known how to do due to her amnesia such as power-housing the Road to Despair considerably better compared to the others or being able to remove Monosuke’s bomb inside of him just from looking at his blueprints without any engineering knowledge in the first place. The price for it, however, is that she can bleed from any orifice depending on how much she’s been using it.
- Reluctant Fanservice Girl: Prairie’s the only one with the most costume changes to boot, due to not being given multiple changes of her Ultimate outfit. She gets walked in while wearing a towel or goes around running in her small pajamas. Part 3 amps it up by having her dressed in a cosplay of 2B and Cammy made by Tsumugi, as well as being provided skimpy lingerie by Monokuma in the Love Hotel.
- Deconstructed after Prairie finds the emails made by Team Danganronpa, learning the true nature of the killing game and who the mastermind is supposed to be. She even deduces that Tsumugi puts her in skimpy cosplays as a form of fanservice, much to her ire.
- Prairie’s Ultimate Outfit has holes in the middle of her jumpsuit that doesn’t hide much of her midriff… much to her chagrin. When she gets roped in into wearing humiliating cosplays and lingerie at one point she starts to miss her old jumpsuit, though.
- Saying Too Much: Monokuma has to make a special rule for Prairie to prevent her from “spoiling” the rest of the students with the knowledge that she knows in Pregame.
- Secret-Keeper: She finds out what Maki’s lab looks like, learning that her talent was a lie earlier than most of the cast although she doesn’t tell anyone. When Maki saves Prairie from Kirumi with her gun, she covers for Maki in the class trial by explaining that the gun was provided by Prairie.
- She Knows Too Much: It comes with Prairie’s threshold of retaining her pre-Ultimate Awakening memories, which is why Monokuma sets up a bunch of rules to restrict the information she can give. Breaking those rules resulted in her early “death” at the end of Part 1 right before she gets to say the name of the organization who kidnapped the students.
- Shrinking Violet: Reconstructed. Prairie starts off as this but noticeably starts to adapt to her old personality as Perfect Blitz, though her shyness can come back after she’s done with an outburst.
- Smarter Than You Look: Despite her appearances (and her recklessness), she can pull some quick-thinking observations that most of the students don’t think about that puts her in the same level as Shuichi in terms of murder-solving skills. It helps that she has her intuition to draw in some foreknowledge to help her think.
- Stage Name: Perfect Blitz. Prairie clearly struggles with that name due to her amnesia and how some of the students revere her for it.
- Stupid Sexy Friend: Prairie has a moment where she laments over how attractive all the guys who she's stuck with are. Not to mention the few Ho Yay moments with Tenko is practically subtext and there’s the small line about Prairie thinking that Himiko has “kissable lips”.
- Tareme Eyes: The way her eyes disarm people into thinking she’s just The Cutie is the last thing Prairie wants people to think of her as.
- Token Mini-Moe: Her abrasive attitude might be comparable to that of Hiyoko, she even has the permanent blush on her cheeks.
- Trauma Button: Develops one recently due to the events of what she’s gone through, Prairie has a panic attack when she has a pillow fight with Kokichi.
- Trademark Favorite Food: Nectarine. Even though she initially had no memories of it, her body has a pavlovian response after laying eyes on it for the first time in the Ultimate Academy.
- Tsundere: Played for laughs. She nails down the Harsh type down to a T. Nobody is safe from this, but this attitude is especially apparent with both Rantaro and Kokichi.
- Weaksauce Weakness: Exaggerated. Prairie’s weakness against boys can get to a point where she would faint out of embarrassment when placed in a humiliating situation with them.
- Youthful Freckles: Most visible on the bridge across her nose, although Angie notes that it’s littered all across her body.
Rantaro Amami
Ultimate Adventurer/Survivor
“Why is it that you're the most beat up out of all of us when the killing game hasn't even started yet?”
- Berserk Button: Attempting to hurt or kill Prairie.
- Monophanie and [[spoiler; Kirumi]] got a taste of Rantaro’s grudge due to the former usurping his attempt to get a Love Hotel Key to see Prairie and the latter for her attempted murders on her.
- Kokichi is probably about to get a taste of this too, based on how he reacted to Prairie's retelling of the previous chapter's events in chapter 4.4, doesn't help that Prairie was actually around to see this and ended up chiding him for being hot-headed considering their promise to improve their attitudes though the new rule Monokuma introduced might have helped in that regard. Not like that means Prairie isn't going to enact revenge on the Supreme Leader.
- Big Brother Instinct: Deconstructed. Although he talks about his sisters in Canon, Prairie gets to experience it first hand because he says she is similar to his sister (to her chagrin). Although she relies on him at first, it becomes a point of frequent conflict when his protectiveness clashes against Prairie’s recklessness. It comes to a head in Part 3 where Prairie and Rantaro become spiteful to each other to the point where other students, even Kokichi, try to mediate between them. They’re trying to work on it by chapter 3.17.
- It gets played with in chapter 2.6 when Prairie hears conflicting information about the amount of Rantaro’s sisters because Pregame Rantaro only mentioned one “sister”.
- Foil: To Kokichi. The two are the closest people to Prairie, but Rantaro is obviously more protective of Prairie while Kokichi seems to fan the flames of her rebellion. Not like both of them can avoid her ire due to Rantaro’s restrictiveness and Kokichi just screwing around with her emotions, nor can it stop her crush on both of them.
- Huge Guy, Tiny Girl: The Huge Guy to Prairie’s tiny girl. He’s not the tallest character in the cast but the gap between their heights (32 cm or 1’) makes it easy to mistake them as siblings instead of peers.
- In Touch with His Feminine Side: Conversed in Chapter 1.1. His first meeting with Prairie has him try to appeal to her “nervous wreck around boys” side by asking her to think that he’s a girl. Prairie can’t, which Rantaro remarks that it offends his femininity.
- Insult of Endearment: Though not as often as Kokichi, Prairie doesn’t hesitate to call him “Avocado for brains” especially while the two of them were still clashing. Kokichi also calls him “Runturdo”.
- Kind Restraints: He is not above locking Prairie in classrooms just to get her to calm down.
- Team Mom: Unlike Kirumi’s role extending to all the students, Rantaro’s role is more prevalent when it comes to Prairie. Shuichi even lampshades it several times by saying Rantaro acts like a different person (in a good way) when Prairie is around.
Kokichi Oma
Ultimate Supreme Leader
“Hey, Mousey-mouse? Just so we're on the same page, I was telling the truth when I said I don't trust you.”
- Beneath the Mask: Although he’s as elusive regarding his true intentions as ever like in canon, Prairie points out that he can’t be tricked or blackmailed into being a murderer because he doesn’t care about anyone or himself in chapter 3.16. The fact that her deductions to his personality manages to get under his skin might actually say something about how he actually feels.
- Considering what happened in canon due to the attempt on his life by Miu, one would wonder how accurate Prairie’s assessment of him was.
- Birds of a Feather: With Prairie in regards to using their cuteness to manipulate others. The difference is that Kokichi uses it consciously compared to her and the other students are more wary of him.
- Foil: To Rantaro. The two are the closest people to Prairie, but Rantaro is obviously more protective of Prairie while Kokichi seems to fan the flames of her rebellion. Not like both of them can avoid her ire due to Rantaro’s restrictiveness and Kokichi just screwing around with her emotions, nor can it stop her crush on both of them.
- The Gadfly: Although he’s already like this in canon, Prairie is unfortunately a target of Kokichi’s mischief since he finds her not boring. Even Kiibo felt glad after Prairie came back from the tunnel because he couldn’t stand being bothered by him in place of her. Overlaps with The Tease since Kokichi easily figures out Prairie’s crush on him and Rantaro, though he harshly says he’s not interested.
- Insult of Endearment: In response to Kokichi’s nicknames for her, Prairie often calls him “Leech”.
- Lack of Empathy: Prairie brings it up in Chapter 3.16, saying that he doesn’t care about anyone or himself enough to be blackmailed or tricked into playing Monokuma’s killing game. His reaction to her words isn’t pretty.
- No Sense of Personal Space: Although it’s a perceived fanon that Kokichi has no sense of personal boundaries with the other students, he especially does this to Prairie because he revels in teasing her.
- O.O.C. Is Serious Business: Subverted. On her second day during her stay in the Love Hotel, Kokichi visits her. Prairie mistakes him as the second guest she needed to enact the Love Suite event with. Cue Prairie going along with Kokichi’s wiles as he makes her proclaim her love for him. Only for Prairie to realize that Kokichi also has the Love Key draped around his neck…
- It's subverted again in 4.3 when during his movie date with Prairie, he starts to show romantic advances towards her to the point of preventing her from leaving a few times. Although there might have been some genuine conversations between the two and Prairie was aware that he might be taking advantage of her crush on him, she's still caught off guard when he cuffs her to the sofa while he almost pretended to kiss her, and then took the Monokubs' blueprints only to rip them to shreds and burn them.
- It doesn't help that after that, he shows another form of OOC where he becomes urgently concerned when Kirumi arrives in front of the AV Room while Prairie was still trapped and helps her escape the alleged Prime Minister of Japan from trying to kill her.
- You Can Always Tell a Liar: Considering his reputation as a liar, that wouldn’t be out of place. Yet he especially likes to badger Prairie about her lies (or denial) to the point of pointing out her ticks while she’s lying in order to get her to improve. Not like she hasn’t ever succeeded in lying right into Kokichi’s face, though.
Ryoma Hoshi
Ultimate Tennis Player
“You seem like a nice girl, but I'm a bad crowd to be hanging around if you're looking to make friends.”
- In Spite of a Nail: Although the manner of it is different compared to canon, he’s still the second person to be a victim in this fic.
Miu Iruma
Ultimate Inventor
“Anyone that tries to hurt Prairie has to deal with me!”
- Fangirl: Miu is shown to be the biggest fan out of the students who know Prairie is Perfect Blitz before the killing game. The two end up as friends, with Miu building an equipment that helps her climb the Wall of the End. But… this ends up becoming one of the motives on why Miu murdered Kaede.
- Gadgeteer Genius: It’s apparent in canon, but her skills get brought up early other than it being used for the disposable camera when she creates a magnet that allows Prairie to climb the Wall of the End.
Korekiyo Shinguuji
Ultimate Anthropologist
“It seems that I'm not the only one that ought to take the suggestion to branch out and create a support system.”
- Odd Friendship: Out of all people, one wouldn’t expect Prairie to get along with Korekiyo. Considering he was one of the people she knew during Pre-game, it makes sense why she wouldn’t be so opposed to befriending him. He’s even offered to let Prairie meet his sister.
Kaito Momota
Ultimate Astronaut
“You're a smart girl, you'll just think of a way to get out of whatever trouble you get into!”
- Groin Attack: He’s a victim of this after he became the visitor during Prairie’s stay in the Love Hotel.
Angie Yonaga
Ultimate Artist
“How does it feel knowing you'll be punished for blasphemy once you pass into the afterlife?”
- Foil: To Prairie, or it seems to be heading that way. While Angie is known to be bright and cheery but clearly hiding her plans behind her smile, Prairie is pretty straight forward on what she intends to do as long as it’s not restricted by Monokuma. Though the development hasn’t happened yet in the fic, it’s clear that Angie is trying to push towards the united cohabitation she intends to enforce with the student council, while Prairie is clearly impatient by everyone else wasting a single minute not figuring out a way out of the academy.
Kirumi Tojo
Ultimate Maid
“It's not wrong to want to feel like a hero to the people you care about, Prairie.”
- Once Done, Never Forgotten: Kirumi’s attempt to murder Prairie twice destroyed any semblance of standing she has with the others. Rantaro, especially, has a long standing grudge and won’t hesitate to call Kirumi out on it when she’s around.
- Facial Horror: Chapter 3.16 reintroduces Kirumi after she tried to kill Prairie and that knowledge was made known to the rest of the class, essentially driving her off from the rest of the class. Although her clothes have changed, the thing everyone notices the most is that the fight did not leave her face unscathed.
- Murder Is the Best Solution: As it had been explored in canon, Kirumi will do anything to get out of the killing game once she learned that she was the Prime Minister of Japan. The only difference being her justification for targeting Prairie thrice, which is the fact that the latter isn’t actually a Japanese citizen in the first place that she doesn’t feel any form of guilt trying to murder her. The second interlude seems to hint she doesn’t actually wish to do so.
- Took a Level in Jerkass: Although her motivations are still the same as in canon, Prairie’s lack of Japanese citizenship shifts Kirumi’s efforts into trying to kill her. Unlike Ryoma, Prairie actually wants to live and this results in Kirumi attempting to kill Prairie right in front of the students and acting like it’s there’s nothing personal about it much to the other students’ horror.
Kaede Akamatsu
Ultimate Pianist
“As a genuine fan, I can say you helped a lot of people with your fame. You still did your best to give back to a lot of us - and you really are an inspiration for a good reason.”
- Bloody Horror: Kaede’s death in this fic is noticeably more grounded than how she died in canon, but it’s still brutal considering Prairie has the front seat to see her face turned into one of Picasso’s work of art with a shot-put ball.
- Redemption Equals Death: The day after Prairie and Kaede coincide after Kaede’s attempted murder and keeping it under the wraps, the latter gets killed by Miu who witnessed what happened between the two.
Shuichi Saihara
Ultimate Detective
“Prairie, we're in a killing game and all you're doing is objecting to it. How can anyone be faulted for wanting to live?”
- Accidental Pervert: While he got his fair amount of moments in canon, this gets brought up when Monosuke tells Prairie that he accidentally found her underwear while investigating her room while she was away. Since then, Prairie has called him “Ultimate Pervert” and “Doormat Perv-hara” behind his back.
- Prairie seems to be ashamed enough to call him those names though as when Kokichi threatened to tell him about it when Prairie wouldn't explain why she still has beef against Tsumugi in the first trial, she was flustered enough to make sure the former keeps silent about it.
Tsumugi Shirogane
Ultimate Cosplayer
“You...! You really live up to the name 'Perfect Bitch', you know that?! You're a terrible person!”
- Shipper on Deck: Lampshaded in Chapter 3.3, much to Tenko’s horror.Tsumugi: I’ve seen the way you look at him though! You know, the two of you would look totally cute toge—
Tenko: No! NO WAY! Prairie would never, right?! ...RIGHT?!
Tsumugi: ...she likes him.
Tenko: *Cries in horror*
Monokuma
Monokuma
The Headmaster of Gifted Inmates Academy
“Go ahead. Keep trying. Keep climbing. The higher you climb, the harder you'll fall in the end...”
- Misery Builds Character: Deconstructed. Monokuma gives Prairie the worst accommodation, rules that hinder her progress to get out of the Killing Game, gives her despair-inducing motives that target her and all around doesn’t bat an eye when she’s injured to the point where she gets hypothermia from staying in her bare-bones room. Some of the Monokubs try to reverse this by giving her an actual bed and a shower after she won them over.
- Villainous Demotivator: Him blowing up Monotaro due to his mutiny serves as one.
Monokubs
Monotaro
“The only thing I'll ever regret is not stepping on you myself with the Exisal!”
- Heel–Face Turn: After some quality bonding time in the Game Room involving a certain arcade machine, Monotaro becomes the first Monokub to defect to Prairie’s side.
- Redemption Equals Death: Poor Monotaro. Right after Kaede’s death, Monokuma immediately outs him as a traitor for the Monokubs in front of the other students and makes him explode as an example for trying to defect from Monokuma.
Monokid
“Let US worry about ourselves, we just wanna get you and your friends OUTTA here in one piece!”
- Heel–Face Turn: Monokid is the second Monokub to defect after he and Prairie spend some time with the Mono-Mono Machine. Both him and Monotaro give her proper living accommodations afterwards and leak some intel for Prairie to learn. He still continues to offer Prairie some insistence after [Monotaro’s death] in more discreet ways, but he still opposes his other siblings frontally though.
Monosuke
“...I don't like you either, but I prefer your trash company more than the idea of waltzin' around alone down here.”
- Sycophantic Servant: Double Subverted. Monosuke started out as one of the Monokubs who would bully Prairie horribly, but him and Prairie establish some form of bond after her outing in the underground Danganronpa offices that ends with her removing the bomb inside of him. The betrayal comes when Monosuke decides to rip up the information she printed out for evidence only to hand them over to Monokuma while she was bleeding out from her backlash, though this doesn’t come as a surprise to her since she still feels some form of guilt from working with the Monokubs due to Monotaro’s death.
Monophanie
“I really hope Ugly dies soon, she's very un-cute!”
- Kick the Dog: Monophanie is probably one of the only Monokubs to consistently bully Prairie without showing any signs of remorse. From physical violence with the Exisal, providing a “special” motive video with her own name, and sticking gum to Prairie’s hair… The only reason she’s toned it down (by not a lot) is because of her crush on Rantaro.
Monodam
“He doesn’t bully me anymore, thank you.”
- Because You Were Nice to Me: Although not directly, Monodam defects from Monokuma’s side because Monokid has stopped bullying him ever since he’s been on Prairie’s side. He even wrote her a letter alongside the Kidwatch as a gift during her stay in the Love Hotel.
