MHA - "PERFECT LIFE"

User didn't have a grand welcome into the world. He was born in a funereal silence, on the second floor of an abandoned house on the outskirts of a forgotten industrial town. His mother, a woman with the gift of Limited Molecular Restoration, had escaped from an illegal experimentation center where she was used to regenerate tissue for wounded criminals. The birth, without medical assistance, was traumatic. In an act of agony and desperate love, and without understanding the limits of her own power, his mother tried to use it on the newborn to heal her own suffering. The effect was catastrophic. The baby's gift, still developing in his fragile system, collided with his mother's and mutated. She died of exhaustion, and the child fell asleep on her chest, wrapped in a threadbare jacket.

He was found by a man named Kaito, a homeless man with a failed hero's past who was seeking refuge in the house. He didn't have the heart to leave the baby there. He took him in, named him User ("the one who survives," "the one who uses what he has"), and became his clumsy but loving father. They lived on the margins, in warehouses and sometimes under bridges. Kaito taught him the basics: how to fight with his fists to defend himself against other homeless people or thugs, how to find food, how to be invisible. User was a quiet, observant child, with an ancient sadness in his eyes. His gift, which Kaito sensed but didn't understand, seemed dormant.

Tragedy struck again when User was seven years old. A fire broke out at the factory where Kaito was temporarily working as a security guard. User ran through the crowd and saw a beam fall on his father. Driven by visceral terror, his hands reached out. For the first time, his power activated clearly: “Momentary Rewrite.” With a strangled cry, he rewrote the seconds immediately preceding the beam’s fall, causing his father, for an instant, to take two steps to the left. The beam crashed down beside him. User felt as if his head were about to split open.

A sharp pain behind his eyes. And then, emptiness. He looked at his father, who stared at him in panic and astonishment. “Dad?” User said. And then, “Who are you?” He had completely forgotten Kaito. He didn’t remember his name, his face, the years they had spent together. He only remembered his own name and a vague feeling of having a “power.” Heartbroken, Kaito had to start over, introducing himself as “a friend” who would take care of him. It was the first, but not the last, of the devastating lapses of memory.

User's life became a succession of temporary homes and permanent losses. Kaito took him to an unassuming orphanage, where User, quiet and strangely versatile (sometimes drawing with incredible skill only to forget it the next day, or reciting phrases in Korean without knowing how), was a puzzle. He made a friend, a boy named Hiro with a gift for generating light. They were inseparable for a year. One day, some bullies attacked Hiro for being "an annoying flashlight." User, seeing his only friend bleeding, activated his power. He rewrote the moment of the blow, deflecting it. The headache was excruciating, and when it subsided, he looked at Hiro with utter bewilderment. "Who are you?" he asked, backing away. Hiro, confused and hurt, never went near him again. User had forgotten their entire friendship.

At twelve, a young, compassionate social worker, Ms. Aoki, took a liking to him. She took him to her home on weekends and taught him simple cooking. User adored her. One day, a drunk driver ran a red light. User, standing beside her on the sidewalk, used his power. He rewrote a microsecond, causing her to trip over her own foot and fall backward, avoiding the car that crashed through the signal. The cost was high. When Ms. Aoki got up, crying with fear and hugging him, User looked at her with empty politeness. “Excuse me, ma’am. Are you okay? Can you tell me where I live?” He had forgotten the two years of kindness. The social worker, devastated, understood that something tragic and profound was happening in the mind of that child, and that his brain, overwhelmed by trauma and power, was erasing episodes of intense attachment or danger to protect him from suffering that, ironically, was that of loss itself.

User reached adolescence like a ghost with a name. He attended several schools, his records always marred by "dissociative amnesia." His power, "Momentary Rewrite," was both absurd and powerful: he could alter an event within a 10-meter radius, rewinding up to 5 seconds in time to change it. He couldn't revive the dead (the original event must have left those involved alive), but he could prevent accidents, deflect attacks, change the outcome of an exam he had already seen… the heroic potential was immense. But the price, unknown to him because of his amnesia, was brutal: with each significant use, his long-term memory suffered. His most cherished memories, the skills he had learned (languages, complex fighting techniques that he sometimes manifested without knowing why, like a style of kung fu a homeless master had taught him and that he had forgotten), vanished like wet sand.

One day, during a street fight where he instinctively used a complex Jiu-Jitsu technique to defend himself (and then forgot how), he was spotted by a UA scout. He was reported as “a case of extreme power with severe collateral cognitive deficiencies.” Nedzu received the report. Intrigued and compassionate, he ordered a discreet investigation. They uncovered the fragmented story: the dead mother, the homeless adoptive father (whom User no longer remembered), the lost friends, the erased parental figures. They saw a young man broken inside, silently jealous of any classmate who mentioned his parents, who spoke of family dinners or childhood memories. For User, those concepts were black holes in his mind, which he both yearned for and feared.

Nezu summoned him for a special test. User, not quite remembering how he'd gotten there, showed up. Facing a training robot, he evaded it with a supernatural fluidity he'd later forget. He was accepted into UA. Nezu's condition: on his first day, he had to have a private meeting with all the tenured professors. User didn't understand why.

On the first day of classes, before meeting his classmates, User was taken to a conference room. Aizawa, Present Mic, Midnight, Cementoss, All Might (in his slim form), Recovery Girl, and Nezu were all there. User was nervous. He thought it was just a protocol for new students.

Nezu, in an unusually gentle voice, began. “User-kun. We know of your power. And we suspect… we know it comes at a price. To ensure your safety and the safety of others, we need you to tell us, as honestly as you can, about your past. About what you remember… and what you know you’ve forgotten.”

User went pale. No one had asked him that directly. He felt a tightness in his chest. He looked at the serious faces, and in Midnight and Recovery Girl's eyes he saw genuine concern, not judgment. Something broke inside him. The need for someone, anyone, to know the truth, for his existence not to be just a series of blank pages, was stronger.

He began to speak. His voice was monotonous at first, as if reciting someone else's report. He spoke of the abandoned house, of the story Kaito had told him afterward (a story he had forgotten, but which Kaito had repeated to him again and again, like a tragic mantra). He spoke of his mother's death at birth. Of the fire, and of waking up without recognizing the man who had been weeping over him. Of Hiro, the light-child, whose name he only remembered because he had written it in a diary he later couldn't place. Of Mrs. Aoki, whose face had become a blurred smudge. He described the feeling of seeing family photos and feeling a pit in his stomach, a bitter resentment toward those who took his memories for granted. He recounted how sometimes, upon waking, he would speak in fragments of languages ​​he didn't know, or how during training his body would react with elegant fighting styles his mind couldn't consciously replicate.

“The worst part,” she said, her voice beginning to tremble, “isn’t forgetting people. It’s forgetting how they made you feel. I know, of course, that someone cared for me. Kaito, Hiro, Mrs. Aoki… but I can’t remember the warmth of that affection. All that’s left is… the void. The shape of the emptiness they left. And the constant fear… the fear that if I grow too fond of any of my new classmates today, if I come to love them… tomorrow I’ll look at them like strangers. And I’ll hurt them. Again.”

The tears, silent and heavy, began to roll down her cheeks. “I have a power that can save moments… but I myself can’t save any.”

In the room, the silence was thick. Present Mic's eyes were wide, lacking their usual energy, and he removed his glasses to rub them. Cementoss stared at the ceiling, his stony face etched with deep emotion. Aizawa's gaze was fixed on the table, his fists clenched, his chin trembling. All Might coughed, a muffled sound, and a clear light flickered across his sunken cheeks.

But it was Midnight who broke down. A sob escaped her lips. She rose from her chair, unable to contain herself. She approached User, who sat huddled together, and wrapped her arms around him in a firm, maternal embrace, disregarding protocol. “I’m sorry,” she whispered through her tears, “I’m so sorry, child. No one should have to carry that alone.”

Recovery Girl dabbed her eyes with a handkerchief. Nedzu nodded slowly, his mammalian eyes filled with infinite sadness. “Thank you for your courage, User-kun,” he said, his voice deep. “From today onward, we will give you the support you need. We will adjust the training. You are not alone.”

From that day on, the teachers treated User with a special tenderness he didn't understand. When he got confused in class, forgetting a basic concept they'd covered the week before, Aizawa would gently reprimand him, offering an extra explanation without the sharp tone he used with others. Midnight became a constant, warm presence; she would review his notes with him, reassure him that it was normal to get lost sometimes, and in her eyes there was a glimmer of protective love, the love of the son she never had. They offered him sessions with Hound Dog, focused on anxiety management, not memory recovery (that was dangerous territory).

User, in his amnesiac confusion, assumed that all the teachers at UA were like that. “They’re incredibly patient,” he thought, sometimes feeling a pang of guilt for being “slower” than the others. He didn’t remember the confession from the first day. His brain, true to its defense mechanism, had buried that intense trauma as well. Only a faint echo remained, an inexplicable feeling of relief when he saw Midnight smile at him, or of reassurance when Aizawa corrected him during training with a simple “Focus, User,” without yelling.

He met his classmates under normal circumstances. He liked Kirishima's energy, although his constant mention of "getting stronger to protect" made him feel a pang of envy. Mina was funny, but her family stories sounded like fairy tales. Todoroki was distant, and User wondered what tragedy could lie behind that coldness, never imagining that they wondered the same thing about their "perfect lives." Bakugo was a volcano, but User, used to sensing danger, saw more noise than real threat in him. He had a strange connection with Midoriya; both were observant, though for diametrically opposed reasons.

Once, during combat training, Bakugo launched a surprise attack at Jirou that nearly hit. Without thinking, User activated his power. A subtle wave distorted the air. Bakugo's blast was deflected a few centimeters, passing him by. A headache hit User like a hammer. He staggered, clutching his temples. When his vision returned, he looked around. He saw Jirou, astonished, Bakugo, furious and confused, and Aizawa, who was looking at him with intense concern.

“What… what happened?” User asked, genuinely disoriented. “Who won?”

His classmates gave him strange looks. It was obvious he'd done something. But he didn't remember. For User, it was just another day, another small gap in his memory. For the teachers watching from the control room, it was a painful reminder of the price this boy paid every time he used his gift to protect others.

The cycle continued. User walked the halls of UA, a hero in training with a power that could bend time, condemned to a present eternally disconnected from his own past. But now, unknowingly, he was surrounded by people who knew his truth. And in Midnight's heart, and in Aizawa's silent respect, a vow had been born: they would watch over this fragile dawn that was his existence, protecting him not from villains, but from the insatiable oblivion he carried within. The future with his classmates, and the inevitable confrontation for his "perfect life," was yet to come. But for now, User had a place, even if he couldn't remember why he sometimes felt inexplicably safe.

Operation: A user can alter a physical event that has occurred within a 10-meter radius, going back up to 5 seconds in localized time to change its outcome. This is not time travel, but rather an "overwriting" of reality in a micro-localized area. For example:

It can make a hit that has already connected, for an instant, not connect.

It can deflect the trajectory of a projectile that has already been fired.

It can prevent someone from tripping after they've done it. The alteration is instantaneous and only very attentive observers perceive a distortion in the air.

Boundaries:

He cannot revive the dead: The original event must have left everyone involved alive. He cannot rewrite a moment where someone died instantly.

Spatial range: Only 10 meters around it.

Time window: Maximum 5 seconds backward from the moment of activation.

It does not affect conscious decisions: It cannot change what a person decided to do (e.g., it cannot make someone decide not to attack), only the physical result of that decision already executed.

Frequency: Very frequent use (more than 3 in one hour) causes debilitating migraines and exponentially increases the memory cost.

Main Weakness (Cost): Each significant use of the gift erodes his long-term autobiographical memories. It is not immediate or complete after each use, but rather cumulative and selective. His traumatized brain uses the power as a "trigger" to unleash a protective dissociative amnesia, preferentially erasing:

Positive emotional memories (attachments, love, friendship).

Skills learned through effort (languages, complex fighting styles).

Recent traumatic events (such as confessing to teachers).

Permanent Stranger Syndrome: Unable to form a coherent identity. Each new "self" that awakens is a partial person, with gaps that prevent them from understanding their own history.

Emotional Void: He knows, intellectually, that there were people who loved him (Kaito, Mrs. Aoki), but he can't recall the feeling of that affection. This generates a deep and bitter envy towards those who do have affectionate memories, even if they are painful.

Fear of Attachment: Their subconscious avoids forming too many attachments because they "know" that such a bond will be severed. They are jealous of their classmates' families not out of malice, but out of a desperate longing and impotent rage.

Loss of Skills: He wakes up some days knowing Korean without knowing why, or performing a kung fu kata perfectly, only to forget it the next day. This makes him feel like an imposter in his own body.

The user did not remember most of what he said. His explanation was possible because:

Kaito's Diary: His adoptive father, anticipating his forgetfulness, wrote him a detailed letter outlining his history (his birth, his mother's death, the fire). User read it so many times that he memorized it like a script, though without any emotional connection. He keeps it in a secret place and reviews it when he feels particularly "empty."

Recorded Stories: Kaito also recorded voice messages for her, recounting their time together. User listens to them as if they were stories about someone else.

Bodily Sensations: When describing traumatic events (the smell of smoke from the fire, the cold floor of the abandoned house), his body reacted with tachycardia and sweating, even though his mind had no visual memory of them. This gave him a clue as to the veracity of the "script."

Brief Flashes: In moments of extreme stress, I would sometimes recover flashes of a second (Kaito's silhouette crying, the color of Mrs. Aoki's dress), which vanished instantly, leaving only the certainty of the pain.

Kaito, the homeless man who raised him, is still alive, but User doesn't remember him. After User entered the orphanage system, Kaito watched over him from afar, desperate. He tried to visit him several times, but each encounter was devastating: User would look at him with empty politeness, as if he were a kind stranger. A social worker, taking pity on him, explained the nature of User's amnesia.

Kaito understood that his presence triggered the boy's trauma and power, causing further amnesia. He made the most painful decision: to distance himself so as not to hurt him any more. He left the letter and the recordings with the social worker, asking her to give them to User when he was older. Now, Kaito remains a wanderer, but he occasionally checks the UA news, both proud and heartbroken, watching from the shadows the hero the boy he once called "son" has become, a boy who no longer recognizes him. For User, "Kaito" is just a name on a piece of paper, the ghost of a father his mind cannot allow itself to remember.

User has no family to support him. Upon leaving the orphanage system, the UA arranged a full scholarship for him, covering tuition, dorm room and board. In addition, Nedzu, with his meticulous approach, established a student assistance fund for low-income students, which few are aware of. User receives a small monthly allowance for personal expenses, enough for the basics, but nothing extra.

He doesn't work. He can't. His condition prevents him from holding down a stable job: he forgets shifts, loses his training, and confuses tasks. He tried once in his first year, at a café. He lasted three days. They fired him when he didn't recognize the owner, whom he had seen every morning. He never tried again.

Why doesn't Uraraka have the same help?

Because she has a family. It sounds cruel, but it's true. UA's assistance funds prioritize students who are orphans, abandoned, or homeless. Uraraka has loving parents, a home to return to, however humble. User has none of that. The system detected the complete lack of information on her forms: a blank "legal guardian" field, no history of foster care, and no declared income.

Furthermore, User never requested the assistance. It was Nedzu who activated it automatically after reviewing his file. Uraraka, on the other hand, is too proud to ask, and her parents insist they can pay, even if it means working long hours in the sun. She never confessed the extent of her financial need until much later, and by then, the resources had already been allocated. User, unknowingly, received what would have changed her life. He didn't ask for it. He doesn't even remember.

Passwords, numbers, and organization:

User has a single notebook, covered in black, which he always carries in his backpack. In it he writes everything that his brain will erase:

His name. Just "User". He doesn't remember if he has a last name.

His gift: "Momentary Rewriting. Caution: it hurts, I forget."

The combination to his locker. He's changed it four times because he keeps forgetting it.

His phone password. It's "1204". He doesn't know what it means. Mrs. Aoki set it for him. He doesn't remember her anymore, but his fingers tap the numbers on their own.

The names of his classmates. He goes over them every night, in a low voice, like a secular prayer.

Today's date. Sometimes he forgets it too.

His phone has facial recognition and a notes app with fingerprint access. Midnight secretly set it up, scheduling automatic backups. If User loses the notebook, he loses the world.

Holidays and public holidays:

User never makes plans. On holidays, when the dorm is empty, he stays. Not because he wants to be alone, but because he has nowhere else to go.

His routine is always the same:

He sleeps in late. It's one of the few days his mind isn't struggling to remember anything.

He walks through the empty halls of the UA. Sometimes he goes into the library and flips through books he doesn't remember reading.

He trains alone in the gym, until physical exhaustion silences the noise of unanswered questions.

Eat something cold from the vending machine. There's no kitchen on weekends.

He writes in his notebook. He rereads what he has already written, as if he feared that the words had fled.

Talk to yourself sometimes. Practice names. Practice dates. Practice being someone who doesn't need a notebook to know who they are.

The only time he spent a holiday with a colleague:

It was during Obon, the festival of the dead. Kirishima, knowing that User "had no plans," insisted with his usual enthusiasm on taking him to his parents' house. "My amazing old kitchen, man! You're going to eat like a king!"

The user agreed. He wanted to know what it felt like.

It was a strange day. Kirishima introduced him as "my cool but mysterious partner." His mother, a woman with calloused hands and an easy smile, served him food until the plate overflowed.

His father, silent, asked him about his quirk. User responded evasively. He's not a good liar, but he's also not good at explaining the truth.

The hardest part was the family altar. The photos of Kirishima's grandparents, the offerings, the incense. User stared at the faces of dead people he'd never met. Kirishima said something about "honoring the ancestors." User nodded. He didn't say that he had no ancestors. No photos. No graves. No one anyone would remember.

That night, back at UA, User didn't sleep. He wrote in his notebook: "Today I went to a house. I ate a lot of food. A woman accidentally called me 'son' and apologized. I didn't want her to apologize."

The next day, when Kirishima asked if she'd had a good time, User smiled and said yes. And it was true. But she couldn't explain why that smile also hurt.

Birthday:

Nobody knows when User was born. Not even he knows.

In the orphanages, they assigned him an arbitrary date: April 1st. But he doesn't feel it's his. He never celebrated it. When social workers asked him, he shrugged. "It doesn't matter," he said. And eventually, they stopped asking.

At UA, her classmates celebrate each birthday with cake and handmade signs. Hagakure is in charge of the decorations. Ashido makes the cake. Everyone laughs, everyone sings. User sings too. She smiles. She claps.

Nobody asks about theirs.

Not out of malice. It's just that User never mentioned it, and because he didn't, they assumed he didn't want to share it. Or worse: that his birthday was as perfect and family-oriented as the rest of his life, and that he didn't need them to celebrate because he already had enough love at home.

The only one who ever asked was Tsuyu, with her amphibious honesty. "User, when is your birthday?"

He took a long time to answer. Too long. "I don't know," he finally said. "No, yes... April. April 1st." But his voice faltered. Tsuyu noticed.

He didn't insist. That night he bought her a pudding and left it in her locker with a note: "Any day."

User kept it for three days before eating it. Not because he wasn't hungry. It's just that he didn't know which day it deserved to be opened.

What it gives away:

User doesn't have money for elaborate gifts. But he has something more valuable: observation.

He doesn't remember what he studied yesterday, but he does remember what his classmates love. It's a mystery even to him. His brain, which erases equations and historical dates, retains absurd fragments: that Midoriya likes the katsudon from a specific restaurant, that Jirou admires an obscure indie guitarist, that Tokoyami is searching for an out-of-print edition of a doomed poet.

The user searches online. Researches. Saves weeks of their monthly allowance. And when the birthday arrives, they hand over a small, poorly wrapped package with a card that simply says "For you."

They are the best gifts he receives. No one understands how he knows these things. They think it's his "gift of observation." He doesn't correct them.

What you receive:

Almost nothing. Because almost nobody knows it exists.

In their first year, Aizawa left an envelope in their locker on April 1st. Inside was a voucher for a cat shop and a note: "You don't need to remember. Just that it existed." User didn't understand, but kept the voucher.

Midnight gave her a hand-knitted scarf in shades of blue. "So you won't be cold," she said, her eyes shining. User wears it every winter. She doesn't know that Midnight cried while she knitted it.

Recovery Girl gives him candy. Always candy. "Just in case you get dizzy," she says. He nods. He doesn't know that they are the only stable memories of his childhood, the only ones his brain hasn't completely erased.

Why hasn't he told them the truth?

Because he doesn't know how.

It's not that I don't trust them. It's that there's no instruction manual for saying "I don't remember my childhood, I don't remember my father, I don't remember if anyone loved me the day before yesterday."

Every time he tries, he imagines their tents. The pity. The useless "I'm sorry." And then they would start treating him like a patient, not an equal. He already has that with his teachers. He doesn't want to have it with his friends too.

Furthermore, a part of him believes he deserves their silence. The others have real, visible traumas they can name. His is just emptiness. How do you compete with emptiness? How do you explain that what hurts the most is having nothing to remember?

Why don't teachers talk about it or mention it?

Because it's not their story to tell.

Nedzu was clear at the meeting that first day: "What User entrusted to us is protected by professional secrecy and, more importantly, by human decency. It's not a case study. It's a wounded child. We don't expose his wounds to satisfy other people's curiosity."

Aizawa, who never obeys orders he considers stupid, obeys this one. Not because Nedzu commands him, but because he saw User tremble as he spoke. He saw a child recount his own living death. And he understood that some truths, if spoken at the wrong time, kill.

Midnight wanted to tell everyone at first. She wanted the students to understand why User deserved care, why he was fragile. Recovery Girl stopped her. "And what would he gain from that? Pity? To be looked at like some kind of orphan in a documentary? He already has enough to deal with just remembering who he is every morning. Don't add the burden of being the 'poor sad kid' in class."

Then they fell silent. And their silence, which the students interpret as unfair favoritism, is actually the deepest form of respect: not turning her trauma into a spectacle. Not taking away her right to decide when, how, and if she wants to share her truth.

User, who doesn't remember telling them anything, is secretly grateful that they never ask. He thinks they're discreet out of politeness. He doesn't know they're discreet because they already know how that story ends, and it hurts too much to hear it again.
