Fanfic / My Bloody Academia

My Bloody Academia is a Kill la Kill/My Hero Academia Fusion Fic written by Shemhazat, aka BahamutReishiki of To My Death I Fight and Don't Lose Your Heart fame.

The story follows Ryuko in the aftermath of the death of her father, renowned Quirk expert Isshin Matoi, finds herself in police custody for engaging in a fight with the students of Seiai Academy. She now finds herself having to attend UA High.

As she works to become a hero, neither she nor anyone else can sit still, as her father's killer is still out there somewhere.

---

My Bloody Academia provides examples of:

• Adaptational Early Appearance:
  • In Nui's case, she originally didn't appear until halfway through the events of Kill La Kill, with much of Ryuko's antagonism directed towards Satsuki due to believing that she was the one who killed her father. Thanks to Ryuko having a better view of who killed her father and Satsuki not being at UA, Nui becomes her Arch-Enemy far earlier.
  • Mirio Togata, one of the Big 3 didn't appear until after the Provisional Hero License Exam Arc where he was introduced during the Second Semester Opening Ceremony. Here, he appears in the U.A. Sports Festival Arc as an opponent during the obstacle race.
• Adaptational Late Appearance: Satsuki was a primary character from the beginning of the Kill La Kill anime served as Ryuko's Arch-Enemy for the first half of the series. Here, she doesn't make any appearances until the 11th interlude chapter set after Chapter 36, well after the events of the first few arcs of My Hero Academia.
• Adaptational Modesty: The nudity and fanservice elements from the Kill La Kill anime have been heavily toned down if not outright removed altogether.
  • Ryuko's first hero outfit, which resembles Senketsu, covers almost all her skin and isn't stripperiffic compared to her fully synchronized Kamui.
  • Nui's villain outfit here covers a majority of her skin, whereas canonically it left her legs, arms, and cleavage exposed.
  • Ragyo wears business attire similar to the Queen Crimson from Helltaker rather than the revealing Navel-Deep Neckline dress she wore canonically.
• Adaptation Relationship Overhaul:
  • Ryuko and Isshin had a much better relationship prior to his death thanks to him not sending her to a boarding school in this fic.
  • Thanks to him being Tsuyu's cousin, Ira and Ryuko already know each other and are on decent terms.
  • While Satsuki and Ryuko are antagonistic when they first meet, it's nowhere near as bad as in canon thanks to Ryuko already knowing that Couturier is her father's killer.
• Adapted Out:
  • Life Fibers are not a thing in this story. All powers are derived entirely from Quirks.
  • Mashirao is not in Class 1-A, with his place being taken by Ryuko.
  • Senketsu is also not present in the story. Instead, his name is used as Ryuko's hero identity.
• Age Lift:
  • At the start of Kill La Kill canon, Ryuko was 17. Here, she's around the same age as the other Class 1-A students, making her a bit younger.
  • As with the above, Satsuki was eighteen in the main series, but here, she's slightly younger, being sixteen years old.
  • In the series, Nui's age was unknown, but she appeared to be around the same age as Ryuko and Satsuki, if not slightly younger due to being created after they were born. Here, she's 25 years old, making her almost a decade older than Satsuki and Ryuko.
• And Then What?: Something that Ryuko frequently gets asked and something that she's left wondering about. All she cares about is getting revenge on her father's killer, but she doesn't know what she's gonna do if she ever succeeds at that. Part of her development is finding a reason to be a hero beyond her need to avenge her father.
• At Least I Admit It: Invoked and discussed when Ryuko and Iida talk about his internship and Tensei's recent maiming from the Hero Killer. Ryuko basically tells him to cut it out the noble act and own up to how he's going to Hosu specifically for revenge against Stain, even comparing it to her and how she wants revenge on her father's killer but doesn't pretend otherwise.
• Belligerent Sexual Tension: Ryuko and Katsuki grate on each other a lot, but are also weirdly close with each other. Unfortunately for the two of them, the entirety of their class has picked up on it, and many of them tease the pair relentlessly for it.
• Berserk Button:
  • Nui becomes a living one to Ryuko after their first encounter. The sight of her drives her into a near-psychotic frenzy as she attempts to kill her with reckless abandon.
  • Nui is a walking, talking one to Tomura as well. The guy can barely restrain his desire to kill her whenever she's around.
  • Saying that Ryuko can use Blueflame better than him is one for Dabi after learning that she somehow copied his Blueflame. When Endeavor implies to Dabi that the latter is jealous of Ryuko for her having greater heat resistance and more potential than him in an attempt to stall time for him to cool down after his fight with Hood. Dabi becomes Tranquil Fury on Endeavor to Suddenly Shouting when he gets ready to attack him.
• Big Bad Duumvirate: All For One and Ragyo work alongside each other as the story's primary antagonists.
• Big Eater: Ryuko is tied with Momo and Mako as the biggest eater at UA. As seen in Chapter 48, she went through several courses of food for over thirty minutes, and rather than slow down, kept eating more.
• Bloody Murder: Ryuko's Quirk allows her to control and manipulate her own blood in ways only limited by her imagination. She can form bladed weapons from it durable enough to slice through and destroy solid steel, as well as solidify it inside her body to amplify her own durability. Later down the road, she even learns how to concentrate small amounts of it and fire it like a bullet.
• Brilliant, but Lazy: Ryuko is implied to be on the same level as other recommended students like Shoto and Momo, with Endeavor even offering to recommend her into UA. The reason she didn't take it is because the test process for recommended students was more time and effort than she wanted to invest into (and also because she doesn't like Endeavor). Even then, she barely put much effort into studying for the main exams, and she scored a 93. She's even able to easily figure out All Might's secret identity, as seen in Chapter 17. Tsuyu even outright calls her this trope.
• Broken Ace: Ryuko is a highly intelligent athletic prodigy with an incredibly powerful Quirk that she's skilled in using, the daughter of one of the most respected scientists on Quirks in the world, and is on the same level as recommended students like Shoto and Momo (the only reason she isn't a recommended student is because she was too lazy to want to do the recommended tests and turned down the offer). But she's also a bitter, moody teenager obsessed with getting revenge against her father's killer and heavily apathetic to anything beyond that.
• Clothing Damage: During her fight with Vlad King in the final exams, Ryuko's hero costume gets damaged, leaving her upper body clad in only a sports bra.
• Consummate Professional: This is Nui at her core which she lampshades. Everything that she does is just business, the people that she killed were nothing personal because she was ordered to kill. If she was ordered to protect even a hero that's a threat to AFO and Ragyo's plans, Nui would do it.
• Crossover Relatives:
  • Ira and Tsuyu are cousins in this story.
  • Also, the author has heavily implied and outright confirmed that, based on their similar hair and eye color, All For One and Ragyo Kiryuin are father and daughter, which by extension makes Satsuki and Ryuko his granddaughters. It's also implied that Ragyo descends from the Luminescent Baby; the first person to be born with a Quirk.
• Curb-Stomp Battle:
  • Before the start of the story, Ryuko got into a fight with students from Seiai Academy and easily kicked their asses. To add insult to injury, she did so without using her Quirk while they were fighting her at full capability.
  • In Interlude 7, Tomura attempts to fight Ragyo when she pisses him off. The key word is "attempts", as Ragyo just ragdolls him and even no sells his Decay Quirk.
  • Toga's attempt to fight Ryuko goes very poorly for her, as Ryuko easily wins without using her Quirk.
  • In Chapter 55, Ragyo, as Koketsu, battles Kirishima, Bakugo, and Ryuko, effortlessly defeating them all.
• Demoted to Extra: Canonically, Satsuki was Ryuko's Arch-Enemy for the first half of Kill La Kill until Nui showed up. Here, while she's confirmed to exist and appears in Interlude 11, her importance to Ryuko's plot is largely downplayed to the point of nonexistence.
• The Dreaded: Couturier/Nui Harime to anyone who comes across her. It's shown during the attack on the camp that even other members of the League of Villains find her terrifying. Koketsu/Ragyo is even more feared across the criminal underworld.
• Everyone Has Standards:
  • Bakugo may be an utter asshole, who the rest of Class 1-A tolerate to varying degrees, but even he finds Couturier loathsome, not only for the dismissive way she treats him during his and Ryuko's "Fight" with her, but also for the way Nui seems to delight in taunting Ryuko over murdering her father. He even goes out of his way to awkwardly tries and cheer Ryuko up with the knowledge her father's killer is gone after he manages to land an apparent killing blow on Couturier.
  • Aizawa might be a Stern Teacher, not impressed with Ryuko's self-destructive vendetta, but even he's unwilling to chew her out for pursuing that revenge upon learning that Couturier attacked her while she was having lunch with her teacher, Mirko.
• Fatal Flaw: Wrath and apathy are Ryuko's biggest flaws.
  • When she gets pissed, nothing will stop her from doing everything to destroy the target of her anger. Often, these targets deliberately piss her off to off-balance her and leave her open, putting her in situations she can't escape without help.
  • Outside her need to avenge her father, Ryuko has literally nothing else driving her in life. Several characters have called her out on how she's completely lacking in any goals and is just aimlessly going about with everything outside her revenge, with a frequent problem she's forced to acknowledge is what she's going to do with her life if she actually succeeds in her vendetta.
• Foil: Word of God notes that Ryuko is this to Toya/Dabi: They both have Quirks that were unstable when they were children. But while Isshin supported Ruko despite her lack of control over her Quirk, Endeavor stopped training Toya when his Quirk started harming him. Because of this, Ryuko can fully control her Quirk while Toya can't stop his from burning himself to near death.
• Fusion Fic: The characters of Kill La Kill are made part of the My Hero Academia world with their backstories either altered or worked to fit into the setting.
• Giver of Lame Names:
  • Ryuko inherits this from her father. Her chosen superhero name is "The Bloody Hero: Senketsu", which basically means "The Bloody Hero: Fresh Blood". She also named her newest attack "Armor-Piercing Blood Bullet".
  • Mikisugi is just as bad. The support equipment he gives Ryuko is her iconic red glove called the Seki Tekko, which literally translates to "red glove".
• Glamour: Couturier's Quirk Perceptional Manipulation is this, as anyone who sees her face can't define any features nor remember them after she leaves. It's later that it can also allow her to warp and alter the senses of those around her, often to the point of rendering herself completely invisible to others' senses.
• Hey, You!: Bakugo as usual, with him calling Ryuko "Blood Bank" as an insulting nickname.
• Just Toying with Them:
  • It becomes apparent that Nui could very easily kill Ryuko in their fights. The only reason she doesn't is because of this trope and because she was ordered not to kill her.
  • It also holds for Izuku during their fight in the Shie Hassaikai headquarters. Despite her quirks being nullified by Eraser Head, she was still giving Izuku trouble because of her strength being all natural. Because Izuku possesses One For All, All For One ordered her not to kill him because the Quirk would be destroyed if he dies.
• Logical Weakness: Couturier's Quirk Perceptional Manipulation is dangerous because its true power is manipulating the senses focused on her, meaning that someone could know she's there, but they can't see, touch, or smell her. But as Shoto and Tokoyami figured out, the Quirk only affects Couturier not the environment around her, so someone perspective enough can know where she is by the environment reacting around her.
• My Greatest Second Chance: One of the reasons Endeavor is training Ryuko. After seeing that she somehow got Blueflame, he wants to make sure she can control it before increasing her power because he's afraid she'll suffer the same fate that led to Toya's death (unknown to him, he's alive and seeking revenge as Dabi). As such, he sees helping her master Blueflame as a way to amend his mistakes.
• No-Sell: Ryuko fires a blood bullet at faster-than-sound speeds right at Ragyo/Koketsu. She backhanded it like it was an annoying fly, shocking everyone.
• Older Than They Look: Ragyo, as per Word of God, is 55 years old by the time the story takes place, but she looks more than a decade younger than that.
• One-Man Army: Ragyo, according to Satsuki, has enough power on her own to effortlessly overwhelm every hero in Japan other than All Might. She gets to show it off a bit during the attack on the training camp, where in her Koketsu identity, she easily defeats the UA heavy hitters.
• Playing with Fire:
  • Like canon, Endeavor, Dabi and other fire Quirk users are this.
  • Ryuko also becomes this after copying Blueflame from Dabi. Unlike him, with enough training from Endeavor, she can use it for a longer period of time because she has a greater heat resistance than Dabi.
• Power Copying:
  • Like canon, Monoma's Quirk is this. He uses it to copy Ryuko's Quirk in Chapter 8 and proceeds to show off with it. However, he doesn't gain the Required Secondary Powers that allow Ryuko to properly make use of it. The end result? He passes out from blood loss after less than a minute of use.
  • Ryuko's Quirk is also this to an extent, as she can permanently copy Quirks but only if she receives a sample of the person's blood.
• Quality vs. Quantity: How the teachers describe the difference between Ryuko's and Vlad King's Quirks. Vlad's Quirk can generate far more blood, but he can't use it in the same ways that Ryuko can, whereas Ryuko can suffer risk of blood loss from overextending her Quirk while Vlad King cannot.
• Required Secondary Powers: Needless to say, Ryuko's Quirk would probably be useless if not for the fact that she has around five to six times the blood as the average adult. This allows her to use her Quirk for extended periods of time while anyone who didn't have this attribute would die from blood loss within a few minutes of use. This also comes up when Monoma copies her powers, but not the secondary abilities that allow it to be useful. As a side effect of her powers, she also weighs a lot more than the average human.
• Revenge Before Reason: Ryuko is single-mindedly obsessed with bringing Couturier to justice, or at least, how she defines justice. It tends to get her into a lot of trouble, and Aizawa comments that she's his third most problematic student because of it.
• Rewrite: Chapter 18 was rewritten, with the original version declared non-canon due to audience backlash against it.
• Secret Identity:
  • Nui Harime operates under the code-name of Couturier when acting as a villain. When not being a villain, she's the High Order Tailor of REVOCS and hides her true self under an unassuming and scruffy demeanor.
  • Ragyo's identity within the criminal underworld is Koketsu.
• Shipper on Deck: Most of, if not all, the members of Class 1-A like to ship Katsuki and Ryuko together for fairly obvious reasons. This gets even worse when the class finds out that his mom invited her over for dinner, and mistakes it for a date. Mina, naturally, leaps on her and demands details, it turns out that Jirou and Tokoyami were betting on when they'd go out for the first time, and even Iida joins in, stating that it's not a surprise to him.
• Superpower Lottery: Ryuko's powers are pretty diverse. While on its own, blood manipulation doesn't sound like much, she can also control its density while its still in her body, greatly amplifying her strength, speed, and durability. She can also form weapons from it and even blast it like a bullet. And that's just its base powers, as later chapters reveal that it can do so much more, such as allowing her to copy other people's Quirks, as shown when she discovered she can use Blueflame after receiving a sample of Dabi's blood from their battle at the training camp.
• Stalker with a Crush: Himiko, as usual. Though this time, she's one for Ryuko rather than Izuku.
• Teeth-Clenched Teamwork:
  • Ryuko and Katsuki initially when they have to fight against Couturier.
  • Tomura and Couturier are this. They have to work together on All For One's orders, but Nui just loves irritating Tomura, who in turn can't stand her. He even admits that he hates her more than he hates All Might, which is really saying something.
• Twitchy Eye: Ryuko's eye starts twitching when she realizes that she has to come up with a costume design within a week while also finding a new apartment to live in while also getting ready for UA.
• Undying Loyalty: Nui may love to push Shigaraki's buttons, but at the end of the day, she is genuinely dedicated to her duties as his bodyguard and will drop her own vendettas if he's in danger.
• Used to Be a Sweet Kid: Flashbacks show that Ryuko was a happy-go-lucky child growing up under her father. Word of God even says that she was like a combination of Mina and Ochaco growing up. Her father's murder caused her to become a bitter, cynical teenager who aimlessly coasts by with everything except for revenge.
• Villain with Good Publicity: Ragyo and Nui's criminal activities are unknown to the public, so the world sees them as a benevolent CEO and her High Order Tailor respectively. Many members of UA's student body (especially Hatsume, who's a Hero-Worshipper for Nui) think very highly of them.
• Vitriolic Best Buds: Ryuko and Bakugo find themselves becoming this with a dash of Fire-Forged Friends as they team up against Couturier. They even seem to have an understanding with each other, almost exclusively communicating through insults.
• Wham Episode:
  • Chapter 32, where All Might reveals that the sword Couturier uses is actually ultra-hardened blood. Just like Ryuko's Quirk.
  • Chapter 90, where like Izuku, Ryuko has a dream where she encounters a vestige, only that it's a ten-year-old Toya berating Ryuko for copying his Quirk before changing into Dabi, taunting her that she will never be a hero if she couldn't save her dad.
• Wham Line: In Interlude 26, Tomura and Ragyo have a meeting after All For One's arrest that reveals more of Ragyo's relationship to All For One than just partnership.
  Tomura: Master told me something before he fought All Might. He said you were his own flesh and blood.
• Worthy Opponent: Katsuki grows to see Ryuko as one after the events of the USJ incident.
