Main Characters' Families
Voiced by: Aya Kawakami (Japanese), Jessica Cavanagh (English)
"I... I said something awful to you... I've always regretted that. Back then... I just gave up on you... but you never quit, Izuku. You kept chasing your dreams. I'm sorry, Izuku. So now I'll be cheering you on with everything I've got!!"
Izuku's mom. Emotional and prone to outbursts of hysterical tears, Inko has raised her son mostly on her own while her husband is away and paying the bills. She is a caring worrywart who is both supportive and protective of her son. She also has a Quirk that allows her to telekinetically draw small objects to her side.
- Adorkable: Like her son, Inko is timid, easily startled, and prone to overreacting. She is a doting mother who is constantly worrying about the safety of her son, panicking to the point that she can barely get across the floor on all fours, pacing back in forth in the hallways, and crying so much that she knocks herself unconscious from dehydration.
- Adult Fear: Imagine what she is feeling, having to time after time get the news that her son is in the hospital with his limbs mangled and his bones broken. Or being told that he was taken to the police station because he was targeted by a villain. It comes to the point in which she asks Izuku to leave after the Camping Trip Arc due to a very serious injury in his arms. It gets so bad that she eventually threatens to pull him out of UA because she fears for his safety and feels she can't trust the heroes.
- Doting Parent: She's always supportive of Izuku.
- Foil: To Masaru and Mitsuki Bakugou. Inko is very involved in Izuku's life, but was unable to properly support him and his dream when it was discovered that he was Quirkless, leading him to become a bullied Shrinking Violet and feeling guilt over this until he gets into UA, after which she does her best to back him every step of the way, but is constantly worrying about his safety. Meanwhile, the Bakugous had a son with an extremely powerful Quirk, but weren't involved enough in his personal life to rein in his explosively increasing ego and temper, which they don't confront until after he gets into UA, leading them to feel guilty over this.
- Formerly Fit: When Izuku was 4, she was thin. In the present, she is a bit chubby. That's because all her stress from parenting by herself caused her to put on weight.
- Glamorous Single Mother: Downplayed. While not precisely ritzy and glamorous, Izuku's home life is pretty stable and happy despite the fact that he just seems to live with his mom. He never mentions any money problems either, despite the fact that Inko is never seen working. An omake reveals that she is still married, and her husband works abroad, which is likely where the majority of her income comes from.
- Locked Out of the Loop: She doesn't know about All Might giving Izuku One For All, something he is shown to be a little guilty about as he often mention how he "hasn't even told mom" about it.
- Mind over Matter: Her Quirk lets her move small objects.
- My Greatest Failure: When it was first found out that Izuku would never have a Quirk, and thus, could never be a hero, his greatest dream, he had a breakdown. Instead of telling him that he could still try to be one, she too broke down, hugging him and crying while telling him how sorry she was. After Izuku gains admittance to UA, she tells him how sorry she is for acting that way and and that she'll fully support him no matter what.
- Ocular Gushers: Chapter 38 shows her being surrounded by a huge pile of tissues. Now we know where Izuku got it from. It's later revealed that she literally passed out seven times during the Sports Festival, two of those were from dehydration after crying so much.
- Out of Focus: She hasn't had a direct appearance since the UA students were asked to move into the dorms for their safety since she's at home while Izuku is at school.
- Parents as People: As much as she wants to support her son, she's only human. When Izuku discovered that he's Quirkless as a child, she didn't realize, at least not at first, that all of her attempts at comforting him only made him feel worse. Later on, she's very conflicted about whether she should allow him to continue pursuing his dream of being a hero in light of how dangerous it is.
- Reality Ensues: She received praise from fans who loved that she's a heavily realistic depiction of a mother in a shonen manga. Mothers usually are not mentioned or are dead in this genre, but Inko is shown as supportive of her son's dream, but also heavily worried about his well being while he is going in life-or-death situation.
- Strong Family Resemblance: She greatly resembles her son, sharing features such as face shape, eye shape, hair and eye color, etc. They are both heavily emotional and kind people and they share some comedic traits too, such as being both Ocular Gushers and making exaggerated faces of surprise. She also is a fan of All Might and has his memorabilia spread around the house, though she doesn't go overboard with it like her son does.
- Yamato Nadeshiko: Inko is a really pretty woman, before and after. She is kind and mature and knows where to draw the line. Her personality has received lot of praise from fans.
- You Gotta Have Blue Hair: Like her son, she has deep green hair.
- You Remind Me of X: According to All Might, she reminds him of Nana, his mentor.
Hisashi MidoriyaIzuku's father, who has yet to appear. He works abroad. He also has a Quirk: he breathes fire. Whether or not that pertains to his job is a mystery.
- All There in the Manual: The only way to know his name is by reading the databook.
- Disappeared Dad: He is only mentioned once by his wife as a guy with a fire-breathing Quirk. It's revealed in his wife's character profile that he is still alive and currently works abroad.
- The Ghost: Only ever mentioned in the beginning of the manga and never again. Yet.
- Playing with Fire: His Quirk is to breathe fire.
- Punny Name: In the databook, it's revealed his name is Hisashi, a pun on hisashiburi - which translates as "it's been a while", something you say to people you have not seen in a long time, reflecting his situation in the manga.

"But you want to be a hero, right? That's fine. You're not... bound by his blood. Decide who you want to become. And be all you can be."
Shouto Todoroki's mother and Endeavor's (Enji's) wife. Endeavor decided to marry her because of her ice Quirk, which he thought would allow them to produce an child with a Quirk powerful enough to surpass All Might. Endeavor's mistreatment of her would eventually take a toll on her sanity, which ultimately led to her throwing boiling water on the left side of Shouto's face due to being disturbed by his growing resemblance to Endeavor. After the incident, she was put in a mental hospital, where she remains.Shouto eventually reconciled with her and the two are slowly patching things up, but her relationship with her husband remains certifiably trashed, even if Endeavor has made some slight moves towards fixing things.
- An Ice Person: Her Quirk and the reason Endeavor had any sort of interest in her.
- Arranged Marriage: How she became Endeavor's wife. She was not a willing party.
- Broken Bird: Forced to marry a horrible person like Endeavor due to his power and wealth and then have about four children so Endeavor could get his perfect successor, whereupon she was forced to defend her son from his abusive training regimen. When her sanity broke, resulting in Shouto's scarring, Endeavor chucked her into a mental institution.
- Easily Forgiven: Played with. Despite her horrible past with Endeavor, Rei has expressed interest in reconciling with him and even defends him when Natsuo claims Endeavor doesn't care at all about their family. However, she notes that she's still far too scared to meet him face-to-face and it's heavily implied it's only because of his recent The Atoner shift that she's willing to do so.
- Elemental Hair: Has stark white hair to reflect her ice-type Quirk.
- Meaningful Name: Her name in kanji means "Cold". Referencing to her ice quirk.
- Moment of Weakness: Her injuring of Todoroki, as it occurred immediately after she had been talking about how much the stress of her situation was getting to her.
- Nightmare Face: That absolutely disturbed look of fear and hate she gave to Shouto the day she burnt him.
- No Name Given: For a very long time. We first see her in the present in chapter 44. Her name is finally revealed to be Rei in Chapter 187.
- Older Than They Look: Not to the extent of Mrs. Bakugou, but Shouto's mother is quite attractive, and looks too young to have had multiple teenage children. Although, given Endeavor's understanding of marriage, it's possible that she was indeed very young when they married.
- Sanity Slippage: When her children started growing and looking more like Endeavor, she succumbed to the stress and had to be sent to a mental hospital after injuring Shouto with boiling water.
- Tears of Remorse: She apologized through tears to Shouto as they spoke in her room at the clinic.
Voiced by: Kate Oxley (English)
Shouto's older sister and Endeavor's second child. She's got a background in education and is one of the few people who has managed to keep relative order in the Todoroki household. She expresses dismay over the parental rift caused by Endeavor's spartan personality and worries about Shouto's well-being.
- Dark and Troubled Past: Implied, due to being the daughter of an Abusive Parent. It's not stated if that predominantly white hair means she has an uneven inheritance of her parents' Quirks, but what is known is that Endeavor didn't want to use her as his successor, be it for want of a son, want of the perfect Quirk inheritance ratio, or something else entirely, and she watched her dad wreak havoc on the family once he got his perfect heir.
- Meganekko: She wears glasses.
- Multicolored Hair: Her hair is mostly white, save for some flecks of red from her father's side.
- Must Make Amends: In the databook,◊ it's stated that she became a teacher in order to compensate for the fact that she couldn't protect her younger brother, Shouto, from their parents.
- Promotion to Parent: Implied to be the one taking care of Shouto considering that their mother's in the hospital and their father... well, it's really better he is not around, anyway.
Shouto Todoroki's older brother, a 19 year old young man in college. Because of his mom's genes, he can easily tolerate cold conditions. He's got a nice personality and wishes the public knew the truth about his father's abusive domestic behavior.
- Affectionate Nickname: His mother calls him just "Natsu"
- Early-Bird Cameo: A boy with white hair showed up in various flashbacks of Shouto's about the rest of his family, that boy seemed to be Natsuo as a kid.
- Parental Neglect: He mentions that he has almost no memories left of Endeavor and sees him more as a stranger than as a father, implying that Endeavor didn't really gave the time of his day to kids besides Shouto. Natsuo also implies the physical abuse was only aimed at Shouto and Rei as well.
- Remember the New Guy?: Apparently, he's been living in the Todoroki household with Fuyumi, Enji and Shouto; although a fleeting moment in Shouto's childhood flashback shows the presence of multiple brothers. Fuyumi explains that he never shows up because he has apparently been busy with college and, possibly, a secret girlfriend.Fuyumi: Ever since he's started college, he's basically never home. I heard he got a girlfriend from one of his classes!
Masaru and Mitsuki Bakugou
Masaru and Mitsuki Bakugou
Mitsuki voiced by: Mari Kiyohara (Japanese), Terri Doty (English)
Katsuki Bakugou's parents. Masaru is his father and Mitsuki is his mother. Both of them have Quirks; Masaru's able to sweat nitric acid, while Mitsuki can produce glycerin. Katsuki's own Quirk was the result of the two fusing, allowing him to form nitroglycerin, as in the main ingredient in dynamite.
- Distaff Counterpart: As far as looks and personality go, Mitsuki is an older and wiser female Katsuki.
- Early-Bird Cameo: At the very end of the Sports Festival arc, Mitsuki is first heard yelling at Katsuki from another room inside their house for yelling just after waking up, because he's working out his frustrations after his disappointing fight with Todoroki by killing the bacteria on his teeth.
- Foil: Katsuki's mom to Inko. Both are Birds of a Feather with their sons, but while Inko is more loving and caring, Katsuki's mom is cruder and prone to screaming. The fact that their sons' behaviors are complete opposites definitely plays a part in how they behave with them.
- Good Counterpart: Mitsuki to Katsuki. She has all the traits he has, both physically and in personality. However, she is considerably Older and Wiser than him.
- Older and Wiser: Mitsuki is this in comparison to Katsuki, in spite of all the other traits they have in common. Despite her fiery personality, she's able to see that her son is being an asshole and willing to call him out on it, though she's kind of a bitch, herself.
- Older Than They Look: Mitsuki is said to look rather youthful for someone who's got a son in their mid-teens. Justified, as her Quirk apparently gives her great skin. This is Truth in Television, as people with oily skin suffer less from wrinkles and other signs of aging.
- Opposites Attract: His mother is as explosive as Katsuki, but his father is a meek Only Sane Man.
- Parental Neglect: Downplayed. His mother understands they should have done more to prevent Katsuki as he ended up being, but they don't seem like bad parents and she is actually regretful of it.
- Parents as People: Mitsuki and Masaru failed in educating their son's behavior while he was still a child. They admit that Katsuki's insanely overblown ego, rudeness, and bad attitude is a failure on their part as parents and that they should have noticed the early signs of his negative personality traits and done something. As a result; Mitsuki is trying to get a hold of her son's personality in his high school years, which doesn't seem to be going that well, as it often devolves into shouting matches, but they're at least trying to resolve the issue.
- Red Oni, Blue Oni: Mitsuki has an explosive temper that matches her son’s, although it only ever seems to be directed toward Katsuki anyway, while Masaru is passive and usually tries to be the peacekeeper.
- Strong Family Resemblance: Mitsuki's appearance is basically a slightly older, female Katsuki.
- Victim Blaming: Mitsuki tells Bakugou that it was his fault he got kidnapped by villains for being too weak. In front of his teachers, no less.

A young boy with an unnamed Quirk letting him grow and fly with wings. He was friends with Bakugou as a child, and helped him bully Midoriya for being Quirkless.
- All There in the Manual: He is the grandson of Dr. Tsubasa, the doctor who diagnosed a young Midoriya as Quirkless. This information is only found, along with his name, within the databook.
- Ambiguous Situation: While heavily implied by Horikoshi in Volume 7 that Tsubasa is connected to the winged Noumu, it is not yet clear whether his Quirk was simply stolen by All For One to give to that Noumu, or if he was actually turned into that very Noumu himself.
- And I Must Scream: Implied. While possibly having been turned into a Noumu, as shown below under Fighting from the Inside, he likely retained a certain degree of his own memories and consciousness in this form. If so, his death by Stain was unintentionally a Mercy Kill.
- The Bully: As a child, he, along with their unnamed friend and Bakugou, often beat up and belittled Midoriya, just for being Quirkless.
- Eyes Always Shut: In both Midoriya and Bakugou’s flashbacks, he is shown looking like this.
- Fat Best Friend: Was this to his Childhood Friend Bakugou back in elementary school.
- Fighting from the Inside: Implied. In the Volume 7 omake, Kōhei Horikoshi gives the "hint" of - "Why did the winged Noumu pick Midoriya out of the whole crowd specifically?" - providing only a sketch of Tsubasa. This question, combined with the actions of that Noumu grabbing Midoriya in its wounded state - heavily implies that not only might it have once been Tsubasa, but that it still retained some subconscious sense of self and memory of Midoriya at that point, possibly because of his connection to its past.
- Good Wings, Evil Wings: Downplayed. His wings manifest themselves as red and draconic, but he is not truly evil, just a mean-spirited bully.
- Growing Wings: How his Quirk seems to work. Episode 1 shows he can instantly manifest and presumably retract both pairs of wings at will.
- Meaningful Name: Tsubasa's name means wing or wings, which fits perfectly with the nature of his Quirk.
- What Happened to the Mouse?: Discussed. In the databook, his profile ends off by noting that - despite being in elementary school with Bakugou, their unnamed friend, and Midoriya - for some reason, he didn’t end up going to the same middle school like the rest of them…
Voiced by: Minoru Inaba (Japanese), Mark Stoddard (English)
A doctor who first diagnosed Midoriya as Quirkless when he was a child. His name is revealed in the databook.
- All There in the Manual: He is the grandfather of Tsubasa, the chubby winged kid who was childhood friends with both Midoriya and Bakugou. This information is only found, along with his name, within the databook.
- Ambiguously Evil: A rather eerie question is what he's up to right now, post-flashbacks. There is a doctor serving in the shadows under All For One who looks similar to Dr. Tsubasa and has the same voice as him. Are they one and the same, or is this just a Red Herring? Given what has been inferred about his grandchild, this is very unsettling, and his role in declaring Midoriya Quirkless and being a Hope Crusher just adds more fuel to the fire.
- Badass Moustache: Sports a rather impressive mustache, as seen in his profile picture above, while also being completely bald.
- Bearer of Bad News: Informs Midoriya that he is Quirkless, which utterly devastates the latter.
- Brutal Honesty: His diagnosis of Midoriya as Quirkless, is followed by then telling him to basically give up any dreams of ever becoming a hero. Take note, Midoriya was just a four-year old kid at this time.
- Labcoat of Science and Medicine: Has this overall look as a doctor, complete with a stethoscope.
- Lennon Specs: Wears these kind of glasses, which are dark green, with brown frames.
- Mr. Exposition: Explains to Inko, and thus the audience in Episode 1, that her son's Quirkless status is due to having two joints in his small toe from birth, whereas Quirk users only have one joint in their small toes.
- Small Role, Big Impact: Only appears within two of Midoriya’s flashbacks, but his diagnosis is responsible for changing Midoriya’s life completely, until meeting All Might years afterward.
A newscaster. His name is revealed in Volume 7. His Quirk is "Big Horn".
- All There in the Manual: He is given a name and a brief backstory in Volume 7.
- Base-Breaking Character: In-universe, he became this after cutting one of his horns off for the sake of his job, as his horns obstructed camera views. While there is a group of viewers that praise him for putting his job over his Quirk, there is another group that derides him for seemingly denying his own Quirk, thus "promoting Quirk discrimination".
- Horned Humanoid: Thanks to his Quirk.
Voiced by: Michiru Yamazaki (Japanese), Cassandra Lee (English)
"Shut up... You're all freaking nuts... Calling yourselves "Heroes" or "Villains" and going around killing each other like idiots. Talking about your Quirks all the time... all just to show off. Idiots."
Mandalay's young nephew. His parents were heroes who were killed in the line of duty. He possesses a Quirk like theirs that lets him generate water.
- Cool Hat: His hat has two spikes sticking out.
- Expy: Of Inari. He's a kid wearing a Cool Hat who talks down to the protagonist for his heroic ideals, because those same ideals got his parents killed.
- Freudian Excuse: Hates superheroism because it cost his parents their lives, and everybody around him would go on about how it was an honorable way for them to die.
- Groin Attack: When Midoriya attempts to introduce himself, Kouta responds by punching him straight in the family jewels. He later apologizes for it in his letter to Midoriya.
- Hero-Worshipper: Though he's loath to admit it, he becomes Izuku's first fan after being saved by him from Muscular. The next time they meet after the Training Camp incident, Kouta has picked out red sneakers to be just like his idol.
- Making a Splash: As both his parents had water-based Quirks, he gets this by default.
- Meaningful Name: His given name contains the character for "sparkling water", while his surname means "flood". Fitting for someone with water powers.
- Must Make Amends: He sends a letter to Midoriya, thanking him for saving him and apologizing for his Groin Attack. He also asks him to heal soon so he can apologize properly.
- Nice Shoes: He asked Mandalay to buy him a pair of red shoes just like Izuku's, which she eagerly points out when the Pussycats stop by the UA dorms and check their street shoes at the entrance for indoor slippers, drawing attention to his new red shoes sitting by her dress heels. Kouta is instantly embarrassed to all heck for being outed for his secret hero worship of Izuku.
- Tears of Fear: The second he lays eyes on Muscular for the first time after the villain sheds his cloak and mask to fight, Kouta realizes this is the monster who murdered his mom and dad and understandably falls apart. He's so distraught that all he can do is cry and scream in panic.
- Troubled Child: Very surly, and talks like someone much older than he actually is to cope with his grief.
- Tsundere: He tries to keep up his tough, surly facade in an effort to hide his Fanboy tendencies towards Deku. He is flustered when Deku tells him he treasured the letter that Kouta sent him while recovering in the hospital.
A young girl who Chisaki claimed to be his daughter. She was held by the Hassaikai, as her Quirk was central to their plans, before being rescued by the heroes.
- Abusive Parents:
- Chisaki is not her father but pretends to be just for the sake of corralling her easier. Eri is being abused by Chisaki, who makes her think she's a weapon being used to and born to destroy people. He drains her blood to use its properties to make quirk nullifying darts. And when she runs out of blood to give, he uses his quirk to break her down and reset her back to normal. Given what's seen of people who have been broken down, it cannot have been a nice experience at all. Mirio is completely horrified when he learns about it.
- Her real mother didn't want anything with Eri after her husband was erased out of existence by the girl's Quirk, so she left Eri into the care of her father (the former boss of the Shi Hassaikai) after telling Eri that she's cursed.
- Adult Fear: In magnificent spades. Eri is a prisoner to a stranger impersonating a parent to exact control over them under pain of death to his enemies and even her, with the power to immediately undo it.
- Back from the Dead: According to Chisaki, she'll be all right if he "destroys" her so long as he "repairs" her immediately — and it's happened before. The prospect of hearing this makes Mirio sick.
- Blessed with Suck: Eri can rewind things to a previous state. A bout of Power Incontinence led to her accidentally erasing her father from existence. Her Quirk then led Chisaki to take an interest in her as a source of Quirk-erasing drug, which he extracted from her body in an excruciatingly painful process.
- Broken Bird: Eri has been abused so much in the hands of the Hassaikai and Overhaul that she has actually resigned herself to bear the suffering out of sheer hopelessness. When she's going to be harmed because Overhaul will fix any damage done to her and is throwing her under the bus, Eri grits her teeth and waits for the inevitable. She is in a near catatonic state when she finally meets Midoriya out of fear and pain, and by the time Midoriya and Mirio meet her in the hospital after the raid, the overall trauma has caused her to forget how to smile. See Powered by a Forsaken Child below.
- Broken Tears: In the middle of being rescued, Eri starts to break down in tears when she sees that the rescue operation is only managing to get heroes brutalized left and right, and they get worse when Chisaki gives a Breaking Speech saying that it was selfish of them to try and rescue her because Eri is unwanted and trying to save her will just result in more pain for her and everyone involved.
- Combination Attack: Eri continually heals Midoriya's wounds to bypass One For All's drawback to pull out one-hundred percent of it's power against Chisaki in the final battle of the internship arc, while Midoriya continuously destroys his own body to keep her from accidentally erasing him.
- Damsel in Distress: She's a young defenseless girl in the Hassaikai's custody who are using her cells as the basis for a drug-dealing operation. Saving her and taking down the Hassaikai are the objectives of the Internship Arc.
- The Dog Bites Back: As Chisaki is about to escape with her during his fight with Midoriya, Eri, reminded of the heroic sacrifices of those who came to save her, uses her Quirk to undo Chisaki's One-Winged Angel and free herself. Eri eventually teams up with Midoriya and uses her Quirk to erase the drawbacks of fighting at One For All at 100% allowing the two of them to defeat Chisaki once and for all.
- Healing Hands: Since her powers let her rewind living things to a previous state, she can essentially make injuries never happen in the first place with a touch. Of course, if she holds on too long...
- Heroic Albino: She has long white hair and red eyes, as shown on the cover of Chapter 153.
- Heroic Sacrifice: A non-deadly one, but Eri decided to go away with Chisaki instead of being saved by Mirio and Midoriya, because she could tell the two would most likely die in a fight between them.
- Hope Spot: She finally manages to escape wherever she was being held captive and finds heroes willing to rescue her... but has to go back for the sake of those heroes' lives.
- Horned Humanoid: Sports a small horn on one side of her head. When her Quirk activates, sparks can be shown coming off of it. Chapter 167 reveals that the horn is where her Quirk originated from, and also that it has shrunken.
- Parental Abandonment: Her birth mother abandoned her when Eri accidentally erased her father from existence when she awakened her Quirk. She's been in his captivity so long she doesn't even know what heroes are.
- Power Incontinence: Eri is evidently unable to control her own Quirk. Her Traumatic Superpower Awakening erased her father from existence, and Chisaki's dialogue indicates she hasn't yet improved in this regard. Deku compares her use of her Quirk as slamming her foot on the gas pedal and unable to get off it. By the time Deku finally defeats Overhaul, her Quirk's gone so far out of control it's only due to Aizawa that Deku isn't Ret Gone either.
- Power Nullifier: She is being used to create anti Quirk bullets. Unlike Aizawa, the bullets attacks the quirk itself instead of just halting the use of one. At least at first. Chapter 156 reveals that it's not exactly a power nullifying Quirk, but a Quirk that can restore a person to a previous state, like rewinding a biological clock.
- Powered by a Forsaken Child: Due to her situation, she is the centerpiece of a huge drug dealing operation, which uses her cells as prime matter to synthesize a drug that nullifies quirks for a given period, but it's implied the drugs are being developed to nullify a person's quirk forever.
- Protectorate: She's this for Mirio and Midoriya from the moment they get her away from Overhaul. Aizawa is later appointed to oversee her since he can stop her with his quirk in case her quirk goes haywire. She is now under the custody of U.A.
- Red Eyes, Take Warning: Played with. On one hand, her Quirk is very dangerous when used improperly. On the other hand, when used properly, it can be very beneficial, and Eri herself is a sweet and adorable girl.
- Ret Gone: One of the applications of her Quirk, which lets her "rewind" living things to a previous state, including to the state in which they never existed. She accidentally did this to her father when her Quirk first awakened, and the bullets that Hassaikai are producing work by rewinding the people they shoot to a state from before humanity first developed Quirks.
- Semantic Superpower: While still operating within certain parameters, her ability has a very broad definition of "rewind." We've seen it erase Quirks but leave everything else unchanged, undo Chisaki's fusion with Nemoto, reset Midoriya's body to an uninjured state, and wipe her father from existence. Chisaki suggests she'd be able to turn a human into a monkey with some effort.
- She Cleans Up Nicely: After being rescued from Chisaki and taken in by the authorities to be healed. She's finally able to lose the rags she was wearing previously and given proper clothing. Looking quite cute in the process.
- Story-Breaker Power: Her power would take all the tension out of the story if she could control it. For example, she could rewind All Might back to his powered-up form, undo all of Izuku's injuries, give back Mirio's quirk, etc. For this reason, the end of the Internship Arc sees her feverish and unconscious in a hospital, incapable of using her powers.
- Superpowerful Genetics: One of the rare Type 2s of this series. Her Quirk is completely unlike any that belongs to her family tree due to a rare genetic mutation that changed it.
- Sweet Tooth: If her reaction to hearing about candy apples is anything to go by.
- Traumatic Superpower Awakening: Eri erased her own father from existence when her Quirk awakened. Her horrified mother left her in the Shi Hassaikai's custody, but it went From Bad to Worse.
- Troubled Child: An abused little girl in the Hassaikai's custody. Midoriya and Mirio greatly regret not saving her when they had the chance.
- Unskilled, but Strong: Justified. Eri's rewinding Quirk verges on being a Story-Breaker Power, but because it only affects living beings and suffers from massive Power Incontinence, it can't be properly trained without having to risk a life in the process as Aizawa notes.
- When She Smiles: After spending nearly her entire page time since her introduction unhappy due to her abuse, she finally breaks out into a huge, happy, uninhibited grin while watching Class 1-A's performance at the Culture Festival. The sight of it clearly delights Mirio.
Masegaki Elementary School Students
A class of mischievous elementary school students that Bakugou, Todoroki, Yoarashi and Camie need to win over for their license exam retaking lessons.
- Adorably Precocious Child: Some of them are very socially-aware for their age, but it's mostly Played for Laughs.
- Badly Battered Babysitter: Their teacher can barely keep up with them, never mind Bakugou and the others.
- Bratty Half-Pint: They're all very hyperactive and mischievous.
- A Child Shall Lead Them: Subverted. There is one sharp-dressed boy who is decidedly not pure of heart and acting as the class's ringleader, smugly coaxing on the rest of the kids and lashing out because he hates how adults are so sure of themselves that they know best and quick to dismiss children like him from having the freedom to be in charge of anything, making all the decisions for them. He is easily frightened into backing down when Bakugou confronts him and has him about ready to wet himself in fear.
- Children Are Innocent: Subverted. The high schoolers are ready to approach them as innocent children, but the boys are all insufferably cocky and scrappy while the girls are already aware of seduction and sex appeal.
- Dirty Coward: The "boss" of the class hangs back and arrogantly leans against a wall acting all confident and mocking the the remedial students when the teens can't get through to the group, but he is easily cowed when he's cornered by Bakugou, evidently hiding behind the other kids he convinced to run wild.
- Kids Are Cruel: The girls slut-shame Camie for taking the boys' attention off them, while the boys are happy to make fun of the hero students assigned to take care of them and attack them with their Quirks.
- Meaningful Name: "Masegaki" can be translated as "precocious brat."
- Troubling Unchildlike Behavior: Some of the boys act like teenage rebels. The girls also partake in Slut-Shaming Camie.
- Unusual Weapon Mounting: One of the kids is capable of turning themselves into a cannon, with the muzzle coming from his mouth.
