Fanfic / Toward A Bright Future

Go To

Toward A Bright Future is a My Hero Academia Fan Fiction by LazyRainDancer.

One day, a young woman is found unconscious on the grounds of the hero school U.A., with no memory of her name or origins, but with a Quirk that allows her to see the future and a warning of a significant villain attack on the students of Class 1-A during their USJ field trip. For the first time in her life, the woman only known as Y/N has the opportunity to change the future and protect the students from harm, and as Class 1-A's newest Teaching Assistant, she'll do her best to make that brighter future a reality.

This fic is in Second-Person Narration, with a new TA who has a mothering attitude and loads of W.A.F.F. to give to her students.

It is complete as of April 2019, ending at the Cultural Festival Arc, but there are several side stories in a collection titled A Series of Fortunate Events, including an adaptations of the two movies My Hero Academia: Two Heroes and My Hero Academia: Heroes: Rising. There are also a series of hug-related drabbles and many other moments in the author's Tumblr page.


Tropes contained in Toward A Bright Future and A Series of Fortunate Events:

    open/close all folders 
    A-D 
  • Abusive Parents:
    • Mumei the barrier villain to Y/N, as her manager and caretaker. He only took her in due to the money she made as an underworld cage fighter, saw it as the only thing she was worth, and regularly abused and belittled her. When he meets her again after she's abducted by the League, he's fully expecting her to return to underground fighting and will not take no for an answer. No wonder she's terrified of him.
    • His ally and twin brother Tokumei is marginally better since he educated her, but barely since he made no effort to get her away from the criminal underworld, until his curiosity was piqued to see if she really could change the future.
  • Action Girl: Downplayed with Y/N. After she starts learning how to defend herself with Aizawa and Shinsou, it comes out that fighting is something her body is intimately familiar with, which makes sense when it's revealed that she was an ex-child cage fighter in the underworld. Even after learning this fact, she won't choose violence as her first option, but when those she loves are in danger, she won't hesitate to throw down. All that said, she still isn't the strongest or fastest around, so she makes use of Hatsume's gadgets and her Combat Clairvoyance to even the odds.
  • Adaptation Relationship Overhaul: In canon, Monoma became good friends with Shinsou after he got into the Hero Course due to both of them being shunned for having unheroic Quirks. Here, it's noted in some posts that Monoma's crush on Y/N has caused some animosity with Shinsou, who views Y/N as an older sister.
  • Allergic to Love: In contrast to many of his peers, Bakugou is distinctly uncomfortable with Y/N being affectionate with him when he does well. When he got a Smooch of Victory for winning an obstacle race, he was visibly flustered, and the one time he lost a spar against Y/N was because he put her in a clinch then realized the situation he was in, causing him to recoil and letting Y/N turn the tables.
  • All There in the Manual: The author puts a lot of side details in posts on their Tumblr page.
    • The specifics of Tokumei's Quirk: he can teleport to anywhere he can see or knows the coordinates of, but he needs to erase memories (his or someone else's) to do so.
    • Y/N's pre-underworld childhood is also detailed in another post, and it's not pretty.
  • Amazingly Embarrassing Parents:
    • A variation: Amazingly Embarrassing Power. Since Y/N finds Dark Shadow so cute, the Living Shadow is constantly asking for pets or stickers or other such treats from her or giving her compliments, much to the embarrassment of his (rather edgy) container, Tokoyami.
    • In regards to actual family members, both Iida and Midoriya are embarrassed when their older brother and mother respectively show Y/N their baby pictures. Iida in particular is mortified that his brother has an entire album of such on his phone.
  • Ambiguously Evil: Tokumei, Mumei's twin brother. He helped educate Y/N, his brother's ward and child cage fighter, never helping her despite knowing the pain and abuse she endured. Only when she declared she would help save the students of U.A. did he decide to help her, purely out of curiosity of if she really could change the future she foresaw, and even then he wiped her memories so he couldn't be traced from her. Much later, he helps Y/N and a newly-met Eri escape from Overhaul, for whatever his motivations.
  • Ambiguously Trained: If you see Y/N in her role as Class 1-A's friendly teaching assistant, you'd never know that her Dark and Troubled Past has her as a big-league underground child fighter called the Prophet. Not even she knows.
  • Amnesiac Hero: Y/N counts, as she has no concrete memories of her home, past or origins, and is unsure of even her own name. All she remembers is her powers and a warning to deliver.
  • And Here He Comes Now: Just as Kirishima is asking Aizawa if they're going to visit Y/N in the infirmary after she is rescued, who should turn up behind them but their other teacher, walking and well.
  • …And That Little Girl Was Me: A variation. Y/N tells Eri, with Fatgum standing nearby, about the first time she smiled during her Dark and Troubled Past as a child cage fighter - when a complete stranger helped her when she was having a fever and gave her the kindest smile she's ever seen, inspiring her to smile too. Said rotund ex-stranger is driven to tears, and Y/N explains to Eri that Fatgum was the one who helped her.
  • Apologizes a Lot: Y/N finds herself doing this a lot to Aizawa and other staff members, especially when she thinks she's not being helpful despite her Quirk. Considering her Dark and Troubled Past and the abuse her guardian Mumei put her through, including threatening to kick her out if she didn't prove herself, it's not surprising.
    • She even apologizes to Bakugou right as the villains take her away during the summer camp attack after she put herself in harm's way to rescue her students. Bakugou really takes issue with this, and when Y/N finds out how much that apology affected him, she apologizes for apologizing.
  • Armor-Piercing Question: After the Sports Festival, Y/N asks Bakugou, if he just wants to be the strongest, why does he want to be a hero whose main purpose is to help people?
  • Ascended Meme:
    • Y/N popularizes the "Dad Might" meme around All Might after taking note of how much he dotes on Midoriya, much to her colleagues' glee.
      • During Two Heroes, All Might tells Midoriya that the two of them share a special bond, that of One For All. He quickly regrets his words when he sees Y/N's giant grin.
    • And then she does the same to the "Dadzawa" meme. Though she is taken a bit aback when Present Mic lets on that she is one of his kids too.
    • And then she does the same to the "Dadgum" meme after she meets Fatgum, and notices how he dotes on his interns Kirishima and Amajiki. She even compares Fatgum and Aizawa squabbling over spending time with her after she is rescued from Overhaul's faction like two divorced parents fighting over custody.
  • Atomic F-Bomb: Hilariously, Heihei the rooster from Moana turns out to give these. While Class 1-A is watching the movie, Kouda, who can understand animal speech, mentions that while half of his screaming translates to regular human screaming, the rest involves words that shouldn't be said around minors.
  • Author Appeal: The author admits that Y/N likes Mario Kart and murder mysteries because they do.
  • Barrier Warrior: One new villain arriving at the USJ attack has this ability, and for some reason, just thinking about him scares the crap out of Y/N. His name is Mumei Kekkai, and turns out he's her guardian.
  • Berate and Switch: During the Wild Wild Pussycat's visit to the U.A. dorms, Kouta starts pulling on Y/N's cheeks and calling her a liar. When he is asked to explain himself, he says, in his usual sullen way, that Y/N told him that she wasn't a hero, yet the actions she took during the summer training camp to save him, Midoriya, and sacrificing her freedom to prevent her students being taken by the League of Villains clearly say otherwise.
  • Big Damn Heroes:
    • Gran Torino and Aizawa pull this to save Y/N from being crushed between Mumei's barriers - Aizawa to cancel his Quirk, Gran Torino to knock him out.
    • The side story Like Minds has Yagi distract a villain who is about to finish off Y/N, and Ryukyu quickly flattens him after.
  • Blood Knight: Rappa of the Eight Precepts of Death is this as in canon. Knowing him from her time in the underworld, Y/N uses him to pass a message on to Fatgum and Kirishima after she was kidnapped by the Precepts - that if he tells them that she's counting on them to save her, they'll be motivated enough to give him the fight of his life.
  • Blessed with Suck: Y/N's Prophecy Quirk counts on many levels; other characters have commented that they've never seen a Quirk with that many drawbacks.
    • At its base, she has no control over her visions, so she gets them sporadically whenever something she sees or hears triggers one.
    • If Y/N tries to outright tell anyone else what she foresees, and if the vision is "important" enough, she gets a splitting headache, and as such has to limit herself to small words. This pain can get erased by Eraserhead's Quirk, but doing so also removes the memories of the vision. There is an apparent correlation between the pain she receives and the importance and inevitability of the event.
    • If Y/N manages to make a big enough change to the future seen in her visions, all the pain from the injuries that would have been suffered by others is inflicted onto her instead (though no actual damage). For example, when she butterflied away the injuries that Aizawa, Thirteen, and Midoriya sustained during the canon USJ attacks, she suffered the pain of broken limbs and a crushed head.
      • Averting someone's death literally leaves her comatose for an absurdly long time.
    • Her Combat Clairvoyance is a potent tool, but overusing it leaves her with light sensitivity, a Psychic Nosebleed, and in the worst cases of overuse, seizures. However, she's slowly training to increase the time limit.
    • She has never received any visions of her own future; she only sees herself when it relates to someone else. Although, Tokoyami did receive a vision of himself and Dark Shadow when his and Y/N's Quirks were temporarily swapped, so it apparently is possible.
      • Later, Midoriya figures out that she sees things based on what she subconsciously wants, like learning more about her students or protecting the girls from Mineta.
    • She breathes involuntarily while receiving visions, and if she is suffocated while in her precognitive trance, the visions will cut off, and worse, she will immediately forget anything she managed to see. Also, repeat visions are incredibly rare.
  • Boxing Lessons for Superman: Y/N starts exercising and practicing her fighting skills along with Shinsou, and she steps up after she gets kidnapped by Stain.
  • Cannot Tell a Joke: Y/N takes note that during a challenge between Classes 1-A & 1-B to cheer her up with jokes or other things, despite instigating the rivalry in the first place, Monoma doesn't have much experience and keeps fumbling the delivery, with Kendou having to save him.
  • Character Development:
    • Y/N finally manages to get through to Mineta that his perverted antics are just not acceptable, and he visibly tones his antics down. On his birthday, he doesn't ask for any additional female attention, and that actually makes his female classmates nicer to him.
    • After Bakugou's Heel Realization and his agreement to talk to Y/N about his issues with Izuku, he visibly tones down his antagonism. In stark contrast to his original statement to Y/N that he'd rather lose than work with Izuku, he joins Izuku and Y/N in taking down Gentle and La Brava before the Cultural Festival, and the two of them make quick work of the gentleman villain.
  • Chased Off into the Sunset:
    • Chapter 17 ends with Y/N placing a sticker on Bakugou's cheek for a job well done during that day's hero lesson and quickly running off, with the explosive boy chasing after her when he sees what she put on him.
    • The ending of the An Egg-traordinary Valentine's Day sidestory, whereupon after a fun Valentine's Day out with both Eri and Y/N, Hawks ends up flying off with Bakugou and Todoroki in hot pursuit, and Iida, Midoriya, and Kirishima trying to stop them.
  • Chekhov's Gun: One time after talking to Aoyama, Y/N gets the idea to get Hatsume to make glitter bombs for her, both to work with his Quirk and as potential distractions just in case. During the Summer Camp arc, Y/N realizes that the marble-shaped bombs look very similar to the prisons generated by the villain Mr. Compress, allowing her to use them as decoys to get him to release his prisoners.
    • Heck, most of the gadgets Hatsume made for Y/N (water gun, smoke bombs, kinetic gloves) come in handy during the whole ordeal.
  • The Chosen One: Midoriya is this even in this fic, as Y/N had visions of him as a young kid throughout her childhood, and his determination to become a hero even while Quirkless helped inspire her through her time as an underground cage fighter. When Nighteye expresses his doubts about Yagi's choice of successor, Y/N wastes no time defending her student.
  • Chronic Hero Syndrome: Y/N describes herself as a busybody who can't help getting involved with new situations purely because she wants to help. Examples include calming down Amajiki whom she runs across having a panic attack and sharing her lunch with him, offering to be a test bed for some of Hatsume's inventions, and in the case of the side story Picture Perfect, offering to be a replacement model when Midnight is called away for hero work.
  • Cliffhanger:
    • Chapter 18 ends with Y/N falling unconscious after being blindsided by the Noumu after the Stain encounter.
    • Chapter 31 ends with Y/N being abducted by the League of Villains from the summer camp right after rescuing her students from them.
    • Chapter 43 ends with Y/N blacking out from her Quirk drawback after successfully averting Togata's Quirk loss and Sir Nighteye's death.
    • The first half of TABF: Two Heroes ends with Y/N confronting David Shield about his plan to stage a fake villain attack, only to be tranquilized from behind by his assistant Sam.
  • Collateral Angst: Even though Y/N was the one kidnapped and is later rescued from the League of Villains, she gives a lot of attention to the six boys from her class who watched her get kidnapped and could do nothing to stop it and were hurting badly because of it. Of special mention are Tokoyami and Bakugou, who were the ones Y/N rescued by putting herself in the line of fire and allowing herself to be kidnapped.
    • In particular, when Midoriya and Bakugou almost come to blows over Bakugou's guilt, Y/N interrupts their fight and then apologizes to Bakugou herself, for not being strong enough to save him without putting herself in danger, for making him watch her disappear, and for not recognizing that he was putting on a strong front and was hurting inside. This interaction goes miles in helping Bakugou absolve himself of his own guilt.
    • Y/N also has a similar talk with Monoma at the end of the Joint Training Arc when, during his match, she hears him blame Midoriya and Bakugou for not rescuing her during the summer camp invasion.
  • Combat Clairvoyance: Y/N rediscovers this facet of her Quirk while practicing with Shinsou, and it goes into full use when she is kidnapped by Stain. It even makes her eyes glow. Unfortunately, she can't use it for very long.
    • It turns out this was her main selling point as an underground child cage fighter — the kid fighter known as the Prophet was a big crowd pleaser as a fighter who could see her opponent's moves before they made them.
  • Comically Small Bribe: After Y/N and Eri are kidnapped by Overhaul's faction, an assisting Toga offers to give Y/N her gadgets back to give them a chance to escape, if she gets to keep the cat-shaped backpack they were in. Given that Toga despises Overhaul for killing Magne, and doesn't exactly want to do this anyway, it's not unjustified.
  • Convenient Coma: Twice so far for Y/N, both times at the hand of her drawback.
    • The first time, she blacked out while held hostage by the League of Villains, after averting the painful removal of Tokoyami's Quirk at All for One's hand. She only wakes up two days later.
    • The second time, she successfully averts Sir Nighteye's death, but collapses in agony moments after. This time, she wakes up 10 days later, and the author mentions that if it wasn't for Eri's reversal Quirk, her coma might have lasted for much longer.
  • Cool and Unusual Punishment:
    • In retaliation for them saying that she doesn't give out good advice very often, Y/N sends Aizawa and Shinsou, both Kindhearted Cat Lovers, pictures of puppies instead.
  • Cool Teacher: Y/N qualifies in spades, giving out stickers and sweets for jobs well done, helping tutor struggling students, and comforting them when they're struggling. When the class moves into the U.A. dorms with her, she even joins them in their video game contests or their cooking endeavors.
  • Crazy-Prepared: When Y/N asks Hatsume for some gadgets for "classroom management", the Support student quickly obliges with a water gun that's strong enough to blast someone off their feet, as well as kinetic gloves that pack a mean punch.
  • Cry into Chest: Y/N does this to Aizawa after she is rescued from the League of Villains.
  • Cuddle Bug: Y/N is very prone to hugging her cute students whenever they do something that makes her smile. One of her first talks with Class 1-A is how much she loves Quirks that are good for hugging, like Tokoyami's or Shouji's.
    • On the other end, Tokoyami's Quirk Dark Shadow would do literally anything to get a cuddle from Y/N and/or give her one, much to the chagrin of his container.
    • Y/N even tells Midoriya later, who is embarrassed at her request for a hug, that heroes need to be good at hugging. When Eri asks if she's right, Midoriya immediately explains why before giving his teacher the hug she asked for.
    • The fact that there's a whole collection of hug prompts says it all.
  • Damsel in Distress: Y/N has unfortunately fallen into this role a few times. It's commented that she's become almost as big a trouble magnet as Midoriya.
    • The first time, she is teleported from buying groceries to meet Stain after he expresses interest in her.
    • Then during the Summer Camp, the League of Villains captures her after she thwarts their attempt to capture her students.
    • And then she and Eri become this when Toga abducts them from the hospital (she was supposed to just take Eri, but Y/N refused to leave her alone). This time though, she manages to convince Toga to give her back her gadgets and allow her to devise a counterplan.
  • Dark and Troubled Past: As bits and pieces of Y/N's past start to appear and get pieced together, such as her always doing the cooking even when she's not obliged to, crying over receiving a smartphone gift, and having a lot of muscle memory in self-defense, Aizawa gets the implication that her missing past was not a good one.
    • After an incident where she forgets a vision because she received it underwater and nearly drowned as a result, Y/N involuntarily apologizes to Aizawa for being useless, promises to be better next time, and asks if she can still stay at U.A. Though Aizawa firmly affirms that the school values Y/N for more than her Quirk and that they'll never kick her out, the fact that she made those statements by habit, as well as other harsh words bubbling up from her memory, paints her unknown past in an even uglier light.
    • Chapter 33 gives Y/N some answers — or at least from All For One and the barrier villain Mumei's perspective - Y/N came from the criminal underworld, where she was a child cage fighter named the Prophet and fought other children for sport and entertainment, and she was one of the best due to her Combat Clairvoyance. Mumei was her manager and caretaker, who only did so for the money she made and habitually abused her otherwise. He left her education up to his twin brother Tokumei, who was the one who left her at U.A. to see if she could really change the future she could predict.
    • This author's post details the rest of Y/N's past: Y/N had a perfectly happy family as a baby, but when she was 3 years old, her Quirk manifested and showed her parents dying on a trip away. Everyone else thought she was overreacting, so the last moment she spent with her parents was her crying her eyes out as they drove away. When her vision came true, her relatives thought her foreseeing their death was a bad omen, so no one wanted to take her in, and the cousin who ended up caring for her sold her to the criminal underworld to pay off a debt.
  • Dark Horse Victory:
    • During a Class 1-A exercise where they have to carry a victim (in this case Y/N) to safety, the one who succeeds is the resident hothead, Bakugou.
    • During a Class 1-B obstacle course race where the winner gets a kiss from Y/N, one would expect the highly-motivated Monoma to win, but the winner ends up being the equally-motivated Kaibara.
  • Date Peepers: The Not a Date variant happens in the sidestory One Surprise After Another. Y/N asks Kaibara to go shopping with her to help her buy a birthday present for Eri, but they end up running into a large number of his 1-B classmates along the way for whatever reason. Unbeknownst to Y/N, Kaibara does wish it were a date.
  • Declaration of Protection: Y/N often makes these in her own thoughts whenever she meets a promising young student. Be they from 1-A like Midoriya, Tokoyami, or Iida, or from other classes like Shinsou, Hatsume, Amajiki, or Togata, she swears that she will do whatever it takes to protect their futures.
  • Defiant to the End: During All Might and All for One's clash, Y/N stands up to Mumei and fights him when he tries keeping her from leaving, and when he manages to trap her between his barriers, she tells him to his face that she'll never listen to him again and she makes her own fate.
  • Determinator: Y/N says that this is the reason she was undefeated as a child cage fighter in the criminal underworld; she was just too stubborn to lose, so her opponents would end up wearing themselves out. She passes that lesson on to Kirishima later.
  • Didn't See That Coming: In A (Not So) Purr-fect Outing sidestory, the assassin Para, who has a Quirk that paralyzes anyone that makes eye contact with her, finds herself taken off-guard when Y/N and her Combat Clairvoyance start blind-fighting.
  • Didn't Think This Through:
    • When Class 1-B decided that the best way to find out about the new girl hanging around Class 1-A was to kidnap her and interrogate her, they really didn't think much beyond that. To cap it off, Vlad King told them to figure out Y/N's deal themselves to teach them how to plan better; shows how well that worked out.
    • In The Two Heroes movie, Midoriya is flustered when Y/N asks him how he'll justify to his classmates why he was invited to I-Island since he can't tell them about his connection to All Might. Y/N helps him out by suggesting they tell anyone who asks that Y/N's invitation allowed her a plus-one, and she took Midoriya since his never-ending supply of trivia makes him a perfect tour guide.
    • Also in The Two Heroes, after getting a vision about David Shield's treachery, Y/N herself probably should've thought her plan through beyond going up and confronting him herself, without telling anyone else to spare All Might's feelings. Though David might be receptive, his allies might not be.
    • In the side story Picture Perfect, Hawks says as much when Y/N calls him over to help with a modelling job that she herself is replacing Midnight in. She was so focused in helping the designer make his shoot a good one that she never considered how it would look for her and Hawks to be modelling wedding attire together, especially considering the Ship Tease the two have shared since then and the overprotectiveness of her colleagues and students.
  • Disappointed in You: Y/N giving the "disappointed teacher" talk to Mineta after his perverted antics happen again at the Summer Camp is what finally seems to get through to him that his antics are just not acceptable. Y/N wonders if she should've had this talk with Mineta sooner instead of simply shutting him down each time.
  • The Dog Bites Back: Toga Himiko doesn't like the Eight Precepts of Death after they killed one of her villain friends Magne, but Tomura ordered her to work with them anyway. As a result, she has no qualms about helping a captive Y/N throw a major wrench in their plans.
  • Do Not Call Me "Paul": Inverted; when Y/N first meets Fatgum, he recognizes her as the underground child cage fighter named the Prophet. An unnerved Y/N quickly says that that's not her name anymore.
  • Don't Ask, Just Run: When the teaching assistant who can see the future grabs two students and pulls them away while saying No Time to Explain, it's best to de-ass the area with the quickness. In this case, before a rogue glacier lands on where they were all standing.
  • Dramatic Irony: During The Two Heroes movie, a main reason why Y/N decides to confront David Shield directly about his fake villain plan to steal back his prototype Quirk Enhancer instead of telling anyone else is that she thinks that there's no way the professor would hire real villains for this scheme due to the danger to everyone.
  • The Dreaded: The silver-haired Barrier Warrior villain to Y/N; even just seeing him in her visions is enough to give her a panic attack. It later comes out that his name is Mumei Kekkai and he was Y/N's guardian and manager while she was an underworld child cage fighter, and he was not nice to her.

    E-K 
  • Ear Ache: Y/N gives two of these to Midoriya and Bakugou simultaneously after they try to resolve a problem with fists instead of words.
  • Embarrassing Old Photo: Turns out Ingenium has a whole album of them on his phone of his little brother (like little Tenya in a tuxedo or a robot costume) and loves to share them at any opportunity, much to Tenya's dismay and Y/N's glee.
  • Entertainingly Wrong: Class 1-B wanted to find out more about the student in a different uniform who keeps hanging around Class 1-A, but since Monoma thought she'd be too high-and-mighty to answer questions, he suggested kidnapping her and interrogating her instead. Unfortunately for him, Y/N isn't a student, she's a teaching assistant. When she tells them so, the entire class freaks out.
  • "Everybody Laughs" Ending: Applies for a few chapters:
    • Chapter 15 ends with Y/N, Midnight, and Mic laughing their heads off at Nedzu's security footage, which had captured Class 1-B panicking over kidnapping and interrogating Y/N, whom they had mistaken for an unusual student instead of a faculty member. Vlad King, on the other hand, isn't laughing as he thinks of how to discipline his class.
    • Chapter 27 ends with everyone laughing at how Todoroki and Uraraka ate the remainder of Y/N's cookies as a Midnight Snack.
  • Exact Eavesdropping:
    • As in canon, Iida is in Hosu City to pick up Ingenium's slack while his brother is on medical leave when a villain attack begins. During the chaos, he is separated from Manual and ends up running into Stain, precisely when Y/N is teleported to Stain to discuss Ingenium's crippled future that Y/N successfully averted.
    • The one time that Tokoyami decided to visit Y/N after she was rescued from the League of Villains, it was the exact time she woke up and told Aizawa and Present Mic about how she had a vision about Tokoyami being captured and painfully losing his Quirk to All for One, which is why she sacrificed herself instead. The guilt weighs heavily on him and Dark Shadow for ages until Y/N finally talks to him about it.
  • Explaining Your Power to the Enemy:
    • In the sidestory A (Not So) Purr-fect Outing, Y/N gets a vision of a three-eyed assassin named Para explaining her paralyzing gaze Quirk to Y/N while she's stalking forward to kill a cat-ified Aizawa. In contrast, once the fight begins for real and Y/N decides to fight with her eyes closed, she doesn't explain her Combat Clairvoyance to Para when the assassin is taken off-guard.
    • The villain Yobi explaining her Quirk of teleporting targets between blood sigils to Y/N is done out of arrogance, which gives Y/N a chance to figure out a workaround.
  • Fights Like a Normal: With the most her Quirk can contribute to a fight being Combat Clairvoyance, Y/N best defends herself with her bare hands, which she is plenty capable of due to her background as a cage fighter. That said, she doesn't have Aizawa's supernal skill in martial arts, so she supplements it with Hatsume's Trick Bombs, a supercharged water pistol, and kinetic gloves.
  • Finale Title Drop: The last line of the main fic is as follows:
    While you had some doubts in the past, you can say with complete confidence now that you’re all walking toward a bright future.
  • First-Name Basis:
    • Fatgum gives Y/N this permission after their first meeting (or rather their second meeting since he saved her once while she was a child-fighter in the criminal underworld and he was undercover).
    • The side stories A Special Bond, A Great Team, Precious Student and Way Too Cute each has someone give Y/N permission to use their first name; respectively, Aizawa, Yamada, Todoroki and Shinsou.
    • The sidestory The Strongest Bond has Y/N use Midoriya's first name while pretending to be cousins for a competition, and while she apologizes for using it without permission, Midoriya admits that he doesn't mind.
  • Flat "What": Aizawa gives out a couple over the story, like when he learns about One For All and how Midoriya only got it the day of the exam (which is why he hurt himself so badly using it), and when he hears that Class 1-B kidnapped and tried to interrogate Y/N.
  • Food as Bribe: Y/N offers Awase from Class 1-B cookies to get him to use his powers to help her fuse a tracking device to a clip that she can use in case she gets kidnapped again.
  • Forgiveness: In Chapter 46, Shinsou apologises to Ojiro for brainwashing him during the Sports Festival, and Ojiro accepts.
  • Forced Transformation: The side story A (Not So) Purr-fect Outing has a random kid's Quirk turn Aizawa and Shinsou into cats, leaving Y/N to take care of them until it wears off.
  • Fountain of Youth: In a few sidestories:
    • The first chapter of A Special Bond has Aizawa regressed to a child by a Quirk while on patrol, and Y/N has to take care of him while it wears off.
    • In Nostalgia, Fatgum gets regressed to the age where he experienced his greatest regretmeeting a sick Y/N while he was an undercover rookie but being forced to leave her behind.
    • Way Too Cute has Todoroki and Shinsou temporarily transformed into 4-year-olds from a kid's new Quirk while out shopping with Y/N.
  • Fuzz Therapy: Kouda's contribution to cheer Y/N up after her near-drowning incident the other day is to give her the cat army she asked for one time. It is very well-received, and she even invites Shinsou to join in.
  • The Glomp: Y/N receives a lot of these throughout the story.
    • Dark Shadow delivers one to Y/N when she sees the class after getting kidnapped by the League, specifically after rescuing Tokoyami and Bakugou. It's quickly followed by a Group Hug dogpile.
      • Then it happens again after she is kidnapped for the third time and put in a coma after being rescued. It plays out exactly the same way both times, even ending in Bakugou berating his classmates for dogpiling her and Shouji pulling her out.
    • Tsunotori later gives one to Y/N for the same reasons.
    • And Kirishima gives another one to Y/N after she awakes from her drawback-induced coma.
    • After Y/N messages Shinsou upon returning to U.A. from the hospital after getting kidnapped for a third time and put into a coma afterwards, Shinsou runs all the way to the dorm and hugs her as soon as he sees her.
    • The highlights of several of the hug prompts:
      • Hatsume hugging Y/N from behind while on a sugar rush.
      • Y/N delivering one to Shinsou after the Joint Training Arc as congratulations for getting into the hero course. On rocket shoes. Complete with a Say My Name. With Eri along for the ride.
      • Ashido giving a distressed hug to Y/N after failing a test despite all of Y/N's help.
    • The Wild Wild Pussycat's visit to the U.A. dorms starts with Ragdoll tackle-hugging Y/N right off the bat.
  • Glowing Eyes of Doom: If you see Y/N's eyes glow blue, it means she can see your every move before you make it. If you see Y/N's eyes glow red, it means she can see your every move and is pissed off as hell.
  • Good Cop/Bad Cop: On the one hand we have the Stern Teacher Aizawa, who can settle down his entire class by just walking into the room and delivering a red-eyed glare or two. On the other, there's his new teaching assistant Y/N, who is always ready to help out struggling students and reward them with smiles, stickers, and sweets.
  • Good Powers, Bad People: Mumei Kekkai has a Barrier Warrior Quirk, but is undeniably evil. As his unwilling ward and child fighter Y/N knows all too well, one of his go-to tactics is to pin and crush his victims between his barriers and the nearest hard surface.
  • Green-Eyed Monster:
    • A few students don't take it well that, because Uraraka and Todoroki are living with Y/N at the school dorms as a trial run, they get first picks whenever she makes treats.
    • Played for Laughs; while Y/N is indulging in some Fuzz Therapy in a large pile of cats, Aizawa and Shinsou, when they see her, both comment, "God, I wish that were me".
    • Monoma has been taking on this air whenever he sees someone else, especially from Class 1-A, gaining more of Y/N's attention, due to his burgeoning Precocious Crush on her.
  • Groin Attack: Averted; Y/N foresees the one that Kouta would give Midoriya when they first meet and pulls the latter out of the way just in time.
  • Group Hug:
    • Y/N finds herself in one with all of the girls of 1-A (and a few guys) after she returns from convalescing after taking on all the pain from the averted USJ attack.
      • And then a second one with dogpiling happens when she returns after being kidnapped by the League of Villains. Quickly followed by a third.
      • Chapter 46 is practically full of them, after Y/N is rescued from kidnapping for the third time.
    • While Aizawa is hugging Y/N after she is rescued from the League, Present Mic decides to joins in. Aizawa orders him off before he breaks his arm, while Y/N is giggling unashamedly.
  • Gut Feeling: While at the Summer Camp, Y/N can't help feeling somewhat uneasy, as if she's seen the forest before and it's nothing good. Of course the readers know what is about to happen, but she has seen the forest before - in a dangerous vision that was erased from her mind because she was drowning in a pool when she had it.
  • Heel Realization: Bakugou finally realizes how big of a bully he'd been to Midoriya, after watching Y/N get abducted by her old guardian Mumei, and realized the look of terror in her eyes when she looked at him was the exact same look Midoriya got whenever he looked at Bakugou himself. This is even more poignant due to a previous conversation where Bakugou claimed he wasn't a bully despite all of Y/N's evidence to the contrary. Moreover, the fact that Midoriya doesn't hate him even after all that he's done has left his worldview majorly askew and him confused if he's a hero or a villain and more pissed off than ever. Y/N promises to help him work through it.
  • Heroic Sacrifice:
    • Just as the League of Villains is about to leave the Summer Camp with their captives, Y/N executes a ploy that manages to put her captured students out of their reach, but leaves herself to be taken instead.
    • In the sidestory A Great Team, Present Mic gives Y/N his headphones so that she's safe from his Quirk when he goes all out to take out a pair of robbing villains, but it means he bursts his own eardrums in the process.
  • Home Sweet Home: After learning that she came from the criminal underworld as a child cage fighter and after being rescued from the League of Villains, Y/N declares that there's no place like home, at U.A. surrounded by her cute, smiling students.
  • Hope Bringer: Y/N outright calls Midoriya this for her; ever since she started getting visions about him, his endless optimism and determination to be a hero despite being Quirkless inspired her to keep going despite her Dark and Troubled Past. When she got the vision about the USJ attack, he was the one who inspired her to stand up, take the first step, and try and change the visions instead of accepting it like all her others before, which piqued Tokumei's curiosity to give her that chance.
  • Hot for Teacher: Though their first interaction was somewhat painful for him, Monoma actually developed a little crush on Y/N due to her encouraging him during a later class, much to his classmates' amusement from all his Luminescent Blushes. For her part, Y/N remains oblivious since she cannot fathom how he could get a crush on her due to said first meeting.
    • Then later, it's shown that Kaibara has also developed a similar crush on her.
  • Hurricane of Puns:
    • All of Chapter 29: "What a Pun-derful Day". Class 1-B even gets in on it too.
    • A part of the Cultural Festival has Y/N, Hawks, and Dark Shadow exchanging bird-related puns while Tokoyami is hiding his face in embarrassment.
  • Is That Cute Kid Yours?: After Eri joins Y/N at U.A., a few people ask if she is Y/N's daughter, including Tetsutetsu and Awase from 1-B.
  • I'm Having Soul Pains: A major drawback of Y/N's Quirk; if she manages to change the future and butterfly away injuries she foresees someone taking in her important visions, all the pain from those injuries are instead inflicted onto her at the time of their occurrence (though no actual damage). The combined pain from broken limbs, injured spines, and even the pain of having one's Quirk removed has laid her out multiple times.
    • If she successfully averts someone's death, as she does for Sir Nighteye, the backlash becomes severe enough that she drops into a coma. It's only the use of Eri's Quirk that keeps the time she spends in that coma down to 10 days as opposed to "indefinite".
  • I'm Taking Her Home with Me!: Y/N bakes some cookies to share with the Wild Wild Pussycat's when they visit U.A.. When Pixie-Bob samples some, she seriously contemplates kidnapping Y/N, and wonders if Aizawa would mind. Class 1-A certainly does, at least.
  • Inelegant Blubbering: After Y/N shares her backstory that she heard from the villains with Aizawa and Yamada, Yamada threatens to start ugly crying if Aizawa doesn't give her a hug.
  • In Spite of a Nail:
    • Despite Y/N's warning, Ingenium still encounters Stain the Hero Killer, but it's mainly because he actively went looking with ample backup. He still loses the fight, but if Stain's recollection is truthful, when Ingenium lets slip about his forewarning yet refuses to name his source despite Stain threatening his life, his staunch protection of Y/N's identity is what convinces Stain to spare him.
    • Although his brother isn't paralyzed for life, Iida Tenya still goes to Hosu for his internship, works with Manual, and encounters Stain, but he only happens upon him by chance and jumps in to protect Y/N whom he kidnapped.
    • Y/N foresaw Midoriya's accidental encounter with Shigaraki while mall-shopping for camping supplies and warned Midoriya appropriately, but Midoriya still accidentally ran into Shigaraki anyway while grocery-shopping for his mother. This incident makes Y/N wonder if the important events of the future really are immutable.
    • Y/N foresaw Todoroki getting into a fight with Yoarashi Inasa during the Provisional License exam and reassured him beforehand, but Todoroki still lost his temper and failed the exam as a result.
  • Internal Reveal: The side story Secrets Revealed, set post-Joint Training Arc, has Bakugou directly asking Midoriya and Y/N about Midoriya's unusual Quirk, and with Y/N's prompting due to one of her visions, Midoriya comes clean about One For All.
  • Invisible Streaker: Y/N averts this with regards to Hagakure, as she reasons that if the Support Department can make a costume to interact with an Intangible Man like Togata Mirio, they can make an invisible one to work with her Quirk. They soon come up with some armor for her.
  • In Vino Veritas: After a mild night of dinner and drinking after the students' final exams, the normally aloof Aizawa thanks Y/N for all the help he has given to his class and for looking out for everyone, prefacing it with a disclaimer that he is drunk, will say something he wouldn't normally say, and that she shouldn't tell him afterwards.
  • I Should Have Been Better:
    • A large chunk of 1-A's boys (Midoriya, Todoroki, Shouji, Aoyama, Bakugou and Tokoyami) feel this after witnessing Y/N being abducted by the League of Villains, after sacrificing her safety to save the latter two boys, while they are helpless behind a barrier. Y/N has to have a long talk with several of them after.
    • In some Tumblr posts Amajiki and Fatgum feel this way after the Overhaul raid, since although they did rescue Y/N and Eri, Y/N was hit badly enough by her Quirk's backlash that she ended up in a coma.
  • Kimodameshi: The sidestory Kindred Spirits has Class 1-A undergo one at Nedzu's behest, which Y/N being an unwilling participant. After the experience hits too many raw nerves, she and Bakugou end up bailing.
  • Kindhearted Cat Lover: If Y/N wasn't one before, she soon becomes one after interacting with Aizawa's two cats, Shiro and Kuro. Her bonding moment with Kouda is asking him to send any stray cats her and Shinsou's way for pets.

    L-P 
  • Last Episode, New Character: The final chapter of the story has the Pro Hero Hawks visit the U.A. Cultural Festival, who is curious about his intern Tokoyami's mysterious TA Y/N.
  • Laugh Themselves Sick: If one thing can consistently set Y/N off, it's Todoroki's Defrosting Ice King personality and status as The Comically Serious after the Sports Festival, be it Pokémon comments, memes, or snarks about his father. It's laid her out on the floor many times and almost caused a segway accident once.
    • Class 1-A descends into hysterics when Y/N says that Dark Shadow won the compliment sticker today - by sending bird puns and emojis via Tokoyami's phone. Even Iida is reduced to laughter.
    • All of All Might's colleagues get a laugh when Y/N starts making Dad jokes at his expense, especially when she mentions a rumor that Midoriya was his illegitimate son. This time Aizawa is the one laughing.
  • Like Brother and Sister: Y/N ends up developing this big-sisterly relationship with Shinsou Hitoshi, whom she meets at lunch at one time. It helps that she's only a handful of years older and he's not directly her student.
  • Locked Out of the Fight: Cut off by the barrier villain, Class 1-A (including ex-prisoners Bakugou and Tokoyami) can only watch helplessly as the League of Villains abduct their teacher Y/N.
  • Loose Lips: During their encounter, Ingenium suffered a head injury and accidentally mentioned to Stain about Y/N and her warning, causing him to turn his attention to her instead.
  • Luminescent Blush: Y/N has caused a lot of these reactions from her students for whatever reason.
    • When Y/N compliments Midoriya on his cheerful smile (or anything about him really), his whole face goes red and he starts sputtering. Everyone else finds it hilarious.
    • Monoma gets this after a few interactions with Y/N and actually developing a Precocious Crush on her, much to the amusement of his classmates. Y/N is oblivious.
    • Iida gets this after he puns for Y/N and she gives him a hug in thanks.
    • When Y/N jokingly declares her love for Kouda after he gives her a cat army to cheer her up, his face goes bright red and he runs away.
    • Y/N gives Amajiki a hug after he saves her from one of Hatsume's wayward inventions, eliciting this response.
    • Finally, Y/N herself gets one — when she gets a kiss on the hand from the visiting Hawks.
  • Mama Bear: As Stain finds out, mess with Y/N's students, and there'll be red-eyed clairvoyant hell to pay.
  • Marshmallow Hell: Y/N suffers this every time Midnight gives her a hug.
    • And then Y/N herself accidentally delivers one to Midoriya, leaving the boy near-comatose (for a couple of reasons) and his classmates either fuming or in stitches.
    • After Class 1-B's performance at the Cultural Festival, Monoma gets bumped by a door and is knocked right into Y/N's chest. He is suitably flustered when he recovers, while his spectating classmates are in hysterics.
  • Mass "Oh, Crap!":
    • Class 1-B's appropriate response when they realize that the girl in the odd uniform that they just kidnapped and tried to interrogate... is a teacher.
    • Class 1-A's reaction after they stay up late socializing with Y/N the night before, and wake up together in a pillow fort with less than an hour until class. At least Y/N provides breakfast for them.
  • Meaningful Echo: Whenever Y/N decides to help out a student she'd just met, like her 1-A students, Shinsou or Hatsume, she comments that she's making an investment in their future. Later, after giving her her official identification documents, Nedzu tells her how much everyone and the school has benefited when he hired her as a teaching assistant, saying that he "made an investment on U.A.'s future" and is reaping the benefits.
  • Missed Him by That Much: During the Summer Camp invasion, Aizawa is off saving students while Y/N is waiting back at the centre, but he returns minutes after she gets a vision of Bakugou and Tokoyami getting abducted by the League and goes off to save them, leading to her getting taken instead.
  • Mistaken for Romance: The side story Warm Hands has Y/N talking with Hawks about going undercover in the League of Villains, but after taking her back to the dorm, her students all think they went on a date.
  • Mood Whiplash: Moments after Y/N interacts with Ms. Joke at Aizawa's expense, Y/N gets a vision of a disguised Toga Himiko going after Midoriya during the exam and seeking his blood.
  • Motive Misidentification: In the side story We've Got Your Back, one of the Big Three's classmates is being extra-clingy to Amajiki for some reason, so Amajiki stays with Y/N for the day while his friends find out what's going on. Turns out their classmate was being clingy towards Amajiki because he was the closest to U.A.'s cryptid, i.e. Y/N, which said classmate was obsessed about.
  • Mysterious Stranger: Y/N was apparently this to U.A.'s third-years, aside from Amajiki. A lot of them had seen her around campus but none of them could figure out her purpose or position, leading Hadou Nejire to nickname her "the cryptid".
    • Y/N later uses this fact to have some fun with the upperclassmen, playing hide and seek with them as she goes to visit the Big Three.
  • Mysterious Waif: The main character Y/N counts. Unknown past? Removed to find herself in unfamiliar surroundings? Strange powers relevant to the plot? Check, check, check.
  • Never Had a Birthday Party: When Y/N admits to Class 1-A that due to her Identity Amnesia she doesn't know when her birthday is (and probably never celebrated it anyway due to her Dark and Troubled Past), they waste no time discussing what day to give her. Y/N eventually decides on a date very important to her - the day she became Class 1-A's TA.
  • Night-Vision Goggles: Y/N designs a new set of these for Aizawa's birthday, with Hatsume's help, great for a hero who works mostly at night. As opposed to his previous goggles that disguise which way Aizawa is looking but do little else, his new set does the same but also provides actual protection from the elements, and are darker to match the rest of his outfit (instead of being bright yellow).
  • No One Gets Left Behind: Sadly averted. When a rookie Fatgum found a feverish child Y/N in a Bad Guy Bar while undercover in his low-fat form, he wanted to get her out of there, but Y/N got a vision of him getting confronted by Mumei and getting badly hurt if he tried, so she ran away. The police busted the place later, but Y/N was nowhere to be found, much to Fatgum's dismay, which has haunted him for years afterward.
  • No Sympathy: When Y/N gets a vision about Present Mic's experience during Class 1-A's year-end exam (which would involve him getting swarmed with bugs), she doesn't tell him what she saw (since that would be unfair to the students he'll be facing) and instead just reassures him that he'll survive somehow. This doesn't comfort him in the least, much to the rest of the faculty's amusement; Aizawa is particularly unapologetic.
    Eraserhead: You’re the best-suited opponent for them, so you’ll just have to deal with it. Besides, you heard her. You’ll survive, so what’s the problem?
    Present Mic: Physically maybe so, but what about my mental health?! Does that not matter to you?!
    Eraserhead: Meh.
    Present Mic: SHOUTA!
  • Not in Front of the Kid: After Class 1-A meets Eri, Y/N has to warn Bakugou not to swear around her, since heroes are supposed to be positive influences. Although she also has to warn his classmates not to antagonize him while Eri is around, as she won't stop him from payback then.
  • Not So Above It All:
    • As Todoroki Defrosts and establishes his credentials as The Comically Serious, almost all of his classmates are stunned that he's slowly learning about memes, Pokémon, and being open to Y/N's sweets, stickers and hugs. Y/N finds it all hilarious.
    • Class 1-B is stunned when their masked classmate Bondo, who they believe has no sense of humor, gets in on the joke war they're having with 1-A and actually succeeds in making Y/N laugh.
  • "Not So Different" Remark: One of the components of Bakugou's Heel Realization - recognizing that the terrified look Y/N gave to the barrier villain Mumei before he abducted her was the exact same one Midoriya got around Bakugou himself.
  • Now You Tell Me: Y/N receives a text from Hatsume that one of her out-of-control inventions has escaped and is pursuing her... moments before said invention comes into view.
  • Oh, Crap!:
    • Mineta gets a lot of these whenever Y/N gets on his case after a vision of him doing something perverted.
    • In a hug prompt, Y/N and Hatsume have this reaction when a laser from one of Hatsume's training drones destroys the remote she was using to control it.
  • One Degree of Separation: While Y/N was a child cage fighter in the underworld, her manager Mumei was often approached by Overhaul for information, and while they discussed things, Y/N helped babysit a young Eri.
    • Fatgum once met her in a Bad Guy Bar while he was undercover, helped her while she was having a fever, and wanted to get her out of there, but Y/N foresaw him getting hurt if he tried and ran away from him. They meet some years later with him as Kirishima and Amajiki's mentor, and several hugs are exchanged after recognition.
    • Y/N also knows Rappa of the Eight Precepts of Death from her time as a child fighter. He's the one who gave her the idea of sweets as a reward.
  • Only Known by Their Nickname: The main character tells everyone that she thinks her name is Y/N but is not entirely sure. Even in the underworld, with people who know her Dark and Troubled Past, Y/N was the name the person who educated her told her to use in public so she couldn't be traced, and everyone else calls her by her underground child fighting ring name — the Prophet.
  • O.O.C. Is Serious Business: Y/N is usually very deferential to Aizawa, so when she vehemently protests his decision to put Midoriya and Bakugou in the same team against All Might, Aizawa and the other staff listen to her and agree to put them on separate teams.
  • Pervert Revenge Mode: Happens any time Y/N gets a vision of one of Mineta's perverted antics, and unerringly gets on his case about it, whether it's her scolding him, enlisting Sero's help, or blasting him with her water pistol. While this does endear her to the girls of Class 1A, Mineta's unrepentant perversion ensures that it only scares him off for a short period before returning to his habit. It doesn't actually stick until she actually has a Disappointed in You talk with him.
  • Platonic Declaration of Love: After Class 1-A finds Y/N's photo wall full of their pictures, Y/N tells them that she can't think of anything she loves more than her students. This causes a large number of them to tell her that they love her too.
  • Please Put Some Clothes On: After receiving a vision of Togata Mirio's full-frontal spar against Class 1-A, Y/N, who is hiding her face in embarrassment, demands that Togata wear his costume during the spar to at least protect the eyes of the girls in her class.
  • Point of Divergence:
    • Thanks to Y/N's warnings, the USJ field trip is scouted out and prepared for, and fewer people are injured as a result (like Aizawa not getting his head smashed in).
    • Forewarned of Stain's attack, Tensei emerges from the encounter injured, but unparalyzed.
    • Because of Y/N's insight into their dysfunctional rivalry, Bakugou and Midoriya are put on separate teams during their final exam. Midoriya is put with Yaoyorozu against Aizawa, while Todoroki is Bakugou's partner against All Might.
    • Bakugou isn't abducted from the Summer Camp by the League of Villains. Y/N is.
      • Also, from one of Y/N's visions, due to the barrier villain's presence, the kids wouldn't be able to stop the League from taking both Bakugou and Tokoyami, and would result in Dark Shadow being painfully removed from her student by All For One. This is what inspired Y/N to protect her students at any cost.
      • As a result, some of Class 1-A doesn't go on a wayward rescue mission. Although Bakugou still ends up feeling guilty for a different reason - being the reason why Y/N was kidnapped.
    • After Y/N receives a vision about Sir Nighteye, she and Yagi go to visit him for a discussion. While the old hero and sidekick are catching up (and delaying Nighteye's meeting with Midoriya and Togata), Y/N goes for a walk and ends up running into Eri, who she knows from her time in the underworld, and helps her escape from Overhaul.
    • Probably the biggest change Y/N's ever enacted so far involves a big helping of the Butterfly of Doom: While she is held captive by Overhaul's faction, Y/N gets the chance to successfully bushwhack his aide Nemoto Shin and keep him unconscious. As a result, he isn't around to shoot Togata with the Quirk-Cancelling bullets, meaning Togata can maintain his advantage and beat Overhaul with no difficulties or interruptions. As a result of that, Nighteye never has to fight and get mortally wounded by Overhaul, successfully averting his death.
      • A side effect of this is because Midoriya never got to fight in this engagement, Nighteye is still unconvinced of his worthiness to have One For All, though Y/N is adamant that he is.
  • Polar Opposite Twins: The case of Mumei and Tokumei. The former is a thuggish villain and Y/N's manager and guardian while she was an underground child cage fighter, who only saw her for the money she could make. The latter is his more formal and refined twin brother, who gave Y/N an education and actually helped put her into U.A. after his curiosity about her changing the future was piqued. Even their Quirks are polar opposites; Mumei's Barrier Warrior Quirk makes him both physical and defensive, while Tokumei's Quirk is both mobile and mental - teleportation at the cost of memories.
  • Power Fist: Hatsume makes a pair for Y/N to enhance her punching power, for "classroom management".
  • Psychologist Teacher: In addition to Y/N's Cool Teacher credentials, she is also fully willing to help her students improve in other ways, such as bolstering Yaoyorozu's confidence, curbing Mineta's perverseness, baking eclairs for the half-French Aoyama to help with his homesickness, and getting Todoroki to move into the U.A. dorms early to get him out from under his father's thumb.
  • Punch Catch: Subverted. Y/N is fighting with her villainous guardian Mumei and when she goes in for a punch he decides to catch it instead of blocking it with his barriers. Unfortunately, the kinetic gloves that Hatsume made for Y/N end up hurling him back and busting his hand instead.
  • Puppy-Dog Eyes:
    • Uraraka pulls these on Y/N to encourage her to keep the pillow fort she created in the dormitory living room around.
    • Y/N does this to get Aizawa to admit that he's happy she's around. While he doesn't admit it, he does blink first, much to Present Mic's glee.

    R-Y 
  • Real Men Wear Pink: In Chapter 46, Aoyama is the first to suggest painting Eri's nails, and the girls are very receptive to the idea. In addition, Todoroki mentions that he'd joined in with nail-painting sessions when it was just him, Y/N, and Uraraka in the dorm. Once the session actually starts, the other boys in the class are soon pulled in.
    • A later pillow fort session has Todoroki open to having his hair styled by the girls, and like before, the other boys are soon also pulled in.
  • Refuge in Audacity: During a pun war between Class 1-A and 1-B, Bondo from 1-B hands Y/N a note that just tells her to pretend there's a funny joke written on it to mess with the rest of his class. The audacity itself makes Y/N break down in giggles and elicits the appropriate response from Bondo's classmates, much to his satisfaction.
  • Retired Badass: The side story Like Minds shows that All Might is still this after his retirement. Even in his weakened form, he doesn't hesitate to punch out a couple of villains and even manages to knock one out.
  • The Reveal: Chapter 33 has Y/N's past revealed to her, courtesy of All For One.
  • Rubber Face: Y/N has done this a few times.
    • She does this to Monoma Neito after he takes responsibility for Class 1-B kidnapping her (without knowing she was a faculty member and not a student).
    • She also does this to Midoriya after he and Bakugou break curfew and almost get into a scrap with each other.
    • Then Y/N gets on the receiving end from Kouta after they meet after the summer training arc, on account of, according to Kouta, her lying that she wasn't a hero when her actions clearly say otherwise.
  • Running Gag:
    • Midnight suffocating Y/N with her hugs.
    • Y/N getting visions of Mineta being a pervert and intimidating him until he stops.
    • Aoyama getting a sticker from Y/N by complimenting her, and everyone else getting jealous. He is eventually upstaged by Dark Shadow using Tokoyami's cell phone.
    • Todoroki showing up for baked treats.
  • Scaled Up: During the Two Heroes movie, just as Y/N is finding a way around the villain Yobi and her teleporting Quirk, she decides to stop playing and turns herself into a large snake, a second Quirk courtesy of All For One, just like her boss Wolfram.
  • Sensei-chan: It's noted that Y/N, a teaching assistant for Class 1-A, is estimated to be only a few years out of high school and a handful of years older than her students, and she's even mistaken for a student by some.
  • Ship Tease: The U.A. Cultural Festival has Y/N getting an interested visitor - the Pro Hero Hawks. She meets him when he offers to guide her through the General Education's Haunted House, chats with her throughout the festival, and ends his visit by giving her his number and a kiss on her hand. Y/N is left with a Luminescent Blush while a few spectators (like Shinsou, Aizawa, and Fatgum) are fuming.
  • Shoot the Fuel Tank: How Y/N finally wins over the villain Yobi during the Two Heroes movie - blasting her malfunctioning Jet Pack with her laser bracelet, producing an explosion worthy of any of Hatsume's malfunctioning babies.
  • Shut Up, Hannibal!: All for One is almost succeeding in breaking his captive Y/N by showing her that there's no mention of her in the news and that U.A. is not looking for her despite all she's done for their students - upon which Y/N defiantly replies that even if she was abandoned, she'd never help the person who would harm her students.
  • Sick Episode: Y/N plays nurse for ill people in two different sidestories. Tender Loving Care has her taking care of Fatgum, in Precious Student, it's Todoroki with a cold.
  • Sitcom Archnemesis: After moving into the dorms, Todoroki and Iida have become this to each other over one particular topic: pillow forts in the living room, where Iida is insistent that they keep the living space clear for everyone, and Todoroki is intent on keeping it up at all costs. Unfortunately for Iida, Y/N and most of the class are in favour of pillow forts more often than not.
  • Sleep Cute:
    • Two words - Pillow Fort. Y/N first made one in the U.A. dorms for Shinsou, and the rest of 1-A (possibly excluding Iida) grow to love it, especially Uraraka and Todoroki.
    • Y/N falls asleep against Fatgum's chest after awakening from her drawback-induced coma and after she escaped from the Eight Precepts of Death.
    • Several times in the sidestories, most commonly in Tender Loving Care and the second chapter of A Special Bond.
    • One hug prompt has Asui fall asleep against Y/N mid-hug due to the cold temperature, and her classmates end up wrapping her in blankets and letting her sleep on Y/N's lap.
  • Small Role, Big Impact:
    • The person who decided to test if Y/N could actually change the future she foresees is never mentioned, until Y/N is kidnapped by the League of Villains and her old guardian Mumei identifies him as Tokumei, a contact that helped to educate Y/N. Later on, Y/N actually meets him, and it's revealed that he's Mumei's twin brother.
    • Principal Nedzu hasn't had as many fluffy scenes with Y/N as compared to Aizawa, Yagi, or Yamada, but he's probably done the most to improve Y/N's lot in life behind the scenes, from hiring her as a teaching assistant, to getting her official identification documents to make up for her missing past, and even offering to help further her own education to become a licensed teacher at U.A.
  • Smooch of Victory: At the Cultural Festival, when the boys of 1-A are planning to have an obstacle course race, Mineta suggests that Y/N give the winner a kiss on the cheek. When Y/N agrees, the resulting competitive spirit leaves her dumbfounded. It ends up being a three-way tie between Bakugou (who just wanted to win and is stunned from the kiss), Todoroki (who accepts it stoically), and Midoriya (who is his usual stuttering, blushing self).
    • And then when the 1-B boys hear about the reward, they have a race too. Despite Monoma copying Todoroki's Quirk to get a leg-up, the winner ends up being Kaibara, who goes really blushingly quiet after his kiss.
  • Spanner in the Works: Toga Himiko during the confrontation with Overhaul. Though she helps capture Y/N and Eri from the hospital, she decides to give Y/N back her gadgets in order for her to sabotage Overhaul's operations, and get revenge for the Yakuza killing Toga's friend Magne.
  • Stealth Hi/Bye:
    • Nedzu has done this to Y/N twice so far - once when he startled her asking for a sucker, and another when he popped up because he forgot to give Y/N her bank card. The second one startled both her and Present Mic into a Security Cling. Y/N is sure that he does this on purpose.
    • During a joke war between 1-A and 1-B, Yanagi keeps sneaking up on Y/N to deliver her jokes. Much like Nedzu, Y/N is sure she's doing it on purpose too.
    • All of Class 1-A panic when Togata sticks his head through the side of their pillow fort to say hi. Y/N finds it hilarious.
  • Straight Man and Wise Guy:
    • Tokoyami and his Quirk, Dark Shadow count as this, especially when Dark Shadow is begging for pets from Y/N while Tokoyami is embarrassed.
    • Aizawa and Yamada count in spades.
  • Super Window Jump: One drabble has Y/N being chased by one of Hatsume's inventions, and her solution is to run to the 1-A classroom and yell for help. Cue Bakugou and Midoriya smashing right out the classroom window to save her.
  • Supreme Chef: Y/N. The students all adore her baking and her non-sweet cooking is also popular, with it being a key factor in her ability to coax Eraserhead into eating better.
  • Sweet Tooth: Todoroki seems to have developed one along with a corresponding significance sense, as he is the first to appear every time Y/N finishes baking some treats.
  • Tastes Like Friendship: Y/N likes cooking, and often has to browbeat Aizawa into eating healthily instead of being too lazy to. Food soon becomes a good way for her to bond with students.
    • She first meets and bonds with Shinsou by sharing her lunch with him.
    • Her first major bonding moment with Todoroki is making his favorite zaru soba after she arranges for him to move into the U.A. dorms as a "trial tenant".
    • She meets Amajiki Tamaki while he's having a panic attack, and gives him her lunch so that he doesn't have to eat in the cafeteria with all the crowds.
  • Team Mom: Y/N ends up 'mom'ing a lot of her students and even Aizawa, especially since she has to stay at his apartment for a while and does her best to make sure he eats healthily instead of living off junk food.
  • Tears of Joy: Abound when Y/N is rescued from the League of Villains.
  • Teleporters and Transporters: Tokumei's Quirk allows him to teleport to anywhere he can see or knows the coordinates of, but it comes at a price; he must erase memories to teleport, either his own or those of the person he's teleporting. Of course, Tokumei is smart enough to find a way around this price (read a lot of books and use those memories to pay the cost of his Quirk), and even uses it as a feature, inducing Laser-Guided Amnesia into Y/N while teleporting her to U.A..
  • Tempting Fate:
    • During an exercise where All Might arranges for Y/N to be carried around by Class 1-A for rescue training, he assures her that everything will be fine and that she'll get a vision if anything goes wrong. Y/N promptly gets a vision showing that no, everything will not be fine, and a lot of drops are in her future unless she does something about it.
    • After watching Iida Tenya be embarrassed by his brother showing his baby pictures, Todoroki asks Y/N if he and Midoriya will have to share theirs as well, to which Y/N says that she'd love to if they have any on hand. Cue Midoriya's mother bursting through the door.
    • Y/N is standing before All for One after successfully averting the fate of her student Tokoyami having his Quirk stolen, and All for One asks where the pain from averting that fate is. Guess what happens moments later.
  • Third Eye: The Quirk of Para, an assassin with a paralyzing gaze and a grudge against Aizawa. She appears in the sidestory A (Not So) Purr-fect Outing, where she takes advantage of Aizawa being turned into a cat to get her revenge, but she doesn't count on Y/N intervening.
  • Third Party Stops Attack: Bakugou and Midoriya are just about to get into a scrap after Midoriya decides to speak on Bakugou's level with his fists when they are both blasted off their feet by Y/N's super water pistol.
  • Those Two Guys: If Yamada/Present Mic isn't being the Wise Guy to Aizawa's Straight Man, he's playing this role alongside Kayama/Midnight. The two of them are often seen laughing at the byplay between Y/N and Aizawa in the staff room, squabbling over Y/N's spare lunch bento, or livening up Y/N's outings while Aizawa is dragged along for the ride.
  • Tired of Running: Y/N, while trying to escape from the League, finds herself locked in a barrier dome with Mumei advancing on her. Though she involuntarily recoils at first, she catches herself, assures herself that she's not the same terrified girl that he wants her to be, and steels herself to fight for her freedom.
  • Trick Bomb: To help keep herself safe in the event of another kidnapping, Y/N has taken to carrying around some special non-lethal bombs made by Hatsume, specifically the smoke, glitter, and sleep gas versions.
  • Tsundere: Y/N thinks that Bakugou is starting to become one around her after his Heel Realization and especially after her numerous kidnappings, both sticking around her to protect her while trying to remain gruff about it.
  • Water Guns and Balloons: Hatsume Mei makes a water gun for Y/N for "classroom management", and being made by Hatsume, it's strong enough to knock someone off their feet if she isn't careful.
    • At the Summer Camp, Y/N and Kouta have a lot of fun drenching the students with these to improve their battlefield awareness.
  • Wax On, Wax Off: Shades of this appear in one of Y/N's lessons, which involves her asking questions to Class 1-A while they're running laps and rewarding them with water. Most of them are standard academic questions, but she also challenges Midoriya to accept compliments without flustering or denying it, and challenges Bakugou to compliment his classmates.
  • Weirdness Magnet: After the Stain incident, Y/N wonders if Midoriya has a secondary Quirk that turns him into a magnet for trouble and if he affected her with it. There's a reason Aizawa often calls her "trouble magnet".
    • As detailed in a Tumblr post, it's gotten to the point that nearly every time Y/N goes shopping, some shenanigans are going to happen. Especially if Midoriya goes with her.
  • Wham Episode:
    • Chapter 32: Y/N is taken hostage by the League of Villains after managing to rescue her students.
    • Chapter 42: Y/N is taken hostage again, this time by Overhaul's faction when she wouldn't let Eri get abducted alone.
    • Chapter 43: Y/N averts Sir Nighteye's death, but suffers her drawback severely enough to put her into a coma.
  • What the Hell, Hero?:
    • Downplayed; after an ill-thought-out kidnapping attempt, Y/N has a pointed question for Vlad King as to why he decided to use her as a target for Class 1-B's information gathering and planning skills, and didn't inform her beforehand.
    • When Y/N hears that Midoriya and Bakugou will be teamed up against All Might for their final exam purely because they don't get along (thus making the exam an attempt to invoke Fire-Forged Friends) and gets a vision about how it will play out (with Bakugou refusing to even listen to Midoriya), she chews out both Yagi for almost breaking Midoriya's back and Aizawa for even suggesting the team in the first place, as Midoriya is already fully willing to team up with Bakugou and thus would get nothing out of the exam, effectively making the exam a test for Bakugou only and a punishment for Midoriya and Midoriya alone.
    • Y/N is preparing to give Sir Nighteye this after seeing him berate Midoriya for not being worthy of One for All.
  • When She Smiles:
    • The first time Todoroki smiles at Y/N after she offers to make him his favorite food, Y/N has to take a moment to recover from the adorableness and thinks that if she ever meets Endeavor, she might just fight him, rankings be damned.
    • Y/N gets really excited when Eri manages to give a tiny smile for the first time while baking with her, though she only fully smiles during the Cultural Festival as in canon.
  • Why Did It Have to Be Snakes?: Y/N is really bad with Horror. During the Cultural Festival, she struggled to go into the Gen Ed class's haunted house despite wanting to see Shinsou's event but managed with Hawks's help. In the Kindred Spirits sidestory, during a Kimodameshi alongside Bakugou, it comes out that Mumei forced her to watch horror movie marathons since he thought her terrified reactions were hilarious, even using them as punishment.
  • Wolf in Sheep's Clothing: Discussed by Y/N and Shinsou after the Sports Festival, about how Midoriya was described as an innocent Mr. Sunshine without mention of his iron-hard punches, and Shinsou ponders if his cuteness is an act to disguise how dangerous and devious he is. All in front of a very flustered Midoriya to tease him.
  • Xanatos Speed Chess: There are dashes of this in the days leading up to the USJ field trip, with Y/N's precognitive warnings of the attack and the League of Villains' moles and a contact who knows about Y/N. Y/N requests to postpone the field trip and the villains don't attack that day. On the postponed day, U.A. takes precautions and scouts out the area, but the villains bring extra reinforcements, including a Barrier Warrior villain who could block tangible attacks. However, Y/N had a vision of that barrier villain moments before and tells Present Mic to get over there immediately, thinking correctly that his sonic shouts could get past the barrier.
  • You Are Better Than You Think You Are: As befitting her Cool Teacher nature, Y/N delivers a lot of talks with this idea:
    • Telling Midoriya (whom she had a lot of visions of for some reason and thus became an inspiration to her) that he'll become a great hero — no, the Number 1 hero.
    • Encouraging Shinsou that with his Quirk, he'll also become a great hero.
    • Encouraging Yaoyorozu after her bad showing at the Sports Festival that she shouldn't second-guess herself and that she has every right to be confident in her own skills.
    • Y/N then becomes the receiver of one talk after the Stain arc, where she was kidnapped by Stain. Y/N apologizes to Tenya, Todoroki, and Midoriya for being a burden who couldn't defend herself and resolves to train to become someone they can rely on, but Todoroki tells her that she is already reliable and that the whole class relies on and respects her more than she knows.
    • When Aoyama comments on how he sometimes dislikes his control over his Quirk and how it can hurt him sometimes, Y/N commiserates with him and compliments him on how far he has come and how he hasn't given up.
    • Comforting the agoraphobic Amajiki Tamaki after he had a bad day at his internship, and reminding him to think of the good parts of his days to cheer himself up, and that his company has already made her day better.
    • After Bakugou's Heel Realization that he was nothing more than a bully to Midoriya, just like the barrier villain that terrified Y/N in her past, while Y/N doesn't absolve him of responsibility, she does tell him that unlike her old guardian Mumei, he has finally recognized his faults and is at least trying to change.
  • You Are Not Alone: When the mere thought of the barrier villain involved in the attack on USJ sends Y/N into a panic attack, Midnight gives her a Cooldown Hug while Nedzu affirms that as long as she is under their protection, the villains will not lay a hand on her.
  • You Will Not Evade Me: During the Two Heroes movie, Y/N makes it to the control room and takes out the enemy technician, only to be teleported to the location of Yobi, one of Wolfram's crew who can teleport anyone who steps on one of her blood sigils to her location. It's the reason Y/N chooses to stay and fight, for if she doesn't stop Yobi, the villain could teleport the Quirkless Melissa Shield to her location if the girl tried to regain control of the security system, who wouldn't stand a chance.
