Author's Note: I never intended to continue this fic, until I needed an idea for Nana's birthday. Gfan97, thank you for giving me so many lovely ideas about Nana reincarnating as All for One's daughter. I lied: it turns out I was cruel enough to do that to poor Nana.

I was determined to give Nana a turn with All for One as her father, but since we don't actually know her birthday, I used Kotaro's birthday (July 13) instead. I don't like Kotaro so I simply wasn't interested in putting much effort into tormenting him. I only bully the characters I love. Also, I was able to fit my idea for Nana into today's Dad for One week prompt ("If you're not with me, then you're my enemy"), so that worked out nicely for me.

All for One did not have a showdown with All Might yet in this AU, and it is unlikely to occur in the future since he is far too distracted with four children, two of whom are incarnations of his old enemies out to sabotage him. As a result, he still has his face.


Nana Shimura knew nothing except darkness and cold. Was she in the Void? She'd last been in the mental landscape of One for All, and then…everything had become hazy. Dimly, she knew time had passed. She'd been…in darkness, but warm darkness. Nothing like this cold. She did not like the cold.

"She's not moving," someone said worriedly. "Should I slap her on the bottom?"

Nana tried to punch the sexual harasser, but her arms felt weak and barely moved. Her eyes snapped open. She stared straight into the crimson irises of All for One.

A piercing scream ripped its way from Nana's throat. She was not the type to scream in the face of a villain, so she tried to stop, but the siren-like wail poured unabated. Tears streamed down her cheeks.

All for One cooed, "What a lovely set of lungs! Aren't you a healthy baby? Yes, you are!" He petted her bald head. "You'll fit right in with the rest of the criers in this family. Ooo! I think she has my nose!"

This did not sound like a villain gloating over obtaining One for All and trapping the vestiges inside. It sounded like a proud father doting over his newborn. At this point, Nana realized that All for One's palm wrapped around her entire head. She'd been swaddled in a blanket and placed in the crook of his arms. She was a baby.

Since the vestiges has started vanishing from the Void one by one, Nana had seen this coming. At first, none of them had understood what was taking them away. Then All Might had run into a white-haired toddler on the street, everyone had discovered that First had reincarnated. It had been a huge relief to know what was happening to them, especially since First had kept his memories and identity. Until All for One had shown up and they'd realized he was poor First's father in this lifetime. Nana had said a prayer for First's soul and wondered where she'd end up reincarnating. It would have been nice if she'd been able to join her children's future family. She'd never dreamed that she might get stuck with All for One as her father, too. First was related to the villain, but why her?

All for One said, "She's your spitting image, dear. Do you think her eyes will turn green later?" He placed Nana in a woman's arms. Nana stared up at Inko's face, her question answered.

Nana had given up her infant daughter Inko for adoption shortly after her birth. If reincarnation was at least partly genetics-based, then this explained why she'd been reborn as Inko's child. But what abominable train of events had led to All for One marrying Nana's daughter? He'd better not have done it on-purpose. She wouldn't put that level of spite past the bastard.

In her shock, Nana had stopped crying. Inko rocked her gently. "What grumpy expression she has, just like Yoichi as a baby."

Nana absolutely didn't want All for One to realize that she was another reincarnated vestige. She immediately smiled and attempted a giggle.

"Aw, she likes me." All for One beamed. "Aren't you the most adorable oopsie baby?"

"Hisashi!" Inko scolded. "You can't call her that to her face!"

"It's not like she can understand me." All for One, aka Hisashi, shrugged.

Nana understood perfectly, and for once found herself in agreement with All for One. This whole situation was a horrible mistake.


Nana did not particularly enjoy the car ride back from the hospital. The rocking kept waking her up from her partial slumber. Hisashi annoyed her by insisting on video-taping her every twitch on his phone. She wondered if he'd kill her if he found out her identity. Though she was tempted to think that would be better than living like this, she couldn't let Inko experience the horror of losing a child. She must keep her secret.

In the doorway, Hisashi called, "Boys, come meet your new sister."

Immediately, three sets of footsteps thundered down the stairs. The children crowded around Inko on the couch. The oldest boy, with white hair and red eyes, looked in his early teens. The second boy was an elementary schooler with curly green hair, green eyes, and freckles. Nana absorbed both children's faces with interest, fascinated to meet her grandsons. Brothers. Same difference.

The youngest boy climbed up the teenager's shoulders to peek. Nana immediately recognized the white hair and green eyes of Yoichi. She wanted to give him a signal about her true identity, but only baby babble emerged.

Yoichi gasped. "She's so tiny! Finally, I'm not the youngest. Tomura, move closer to let me see."

Tomura pushed Yoichi down from his shoulders. "Get off. Dad said I get to hold the baby first."

"That's right." Hisashi placed Nana into Tomura's arms. "I'll let you name her, just like how I named my younger brother. It's an oldest sibling's privilege."

Tomura held Nana awkwardly, as if afraid to hurt her if he moved. "I want to call her Hana, after my sister."

Nana stiffened. Did the family have another child? Why did he say that in such a sad tone? Or was Tomura adopted? He looked a lot like Kotaro, though.

"That's a lovely name," Inko said gently. "Izuku, it's your turn."

Izuku took Nana into his arms with an earnest expression. "I think she smiled at me!"

Nana hadn't been able to help smiling as soon as she'd looked into his eyes. How had All for One produced such a cute angel? It must be the Shimura genetics at work.

"Your turn next, Yoichi," Inko said. "Come sit in my lap, and I'll help you support the baby."

Yoichi climbed into Inko's lap. She placed Nana into his hands, then wrapped both her arms around him. Yoichi gazed down in awe. "I remember being so tiny."

Inko laughed. "You can't remember being a baby, sweetie."

"Oh, I wish I could forget all the diaper changes," Yoichi mumbled. His face brightened. "According to the household policy of older siblings having absolute authority over younger ones, does this mean I finally have someone to boss around?"

Nana flinched. She'd better tell First her real identity as quickly as possible.

Inko growled, "Hisashi, are you still telling the children that nonsense?"

Clearly dodging the question, Hisashi sniffed the air and said, "I think Hana needs a diaper change." He bent over to pick her up.

As All for One's giant face loomed over her, Nana screamed and punched him by reflex.

Her baby fist bounced off his forehead. Hisashi laughed. "What a little fighter! Maybe I finally found a child who will inherit my empire."

Inko shook her head. "You're always so dramatic about your business, dear."

Yoichi rolled his eyes and mouthed, "Villain."

Desperate to escape, Nana tried to squirm out of All for One's arms. Who cared if she hit her head on the floor? Maybe then this would all turn out to be a nightmare!

"She's falling!" Yoichi screamed.

"I'll save you!" Izuku cried.

Both boys leapt forward, smacked their foreheads together, and fell on their backs.

"Doing that again?" Hisashi sighed, easily capturing Nana between his large hands and holding her close to his chest.

They did this on a regular basis? At least Izuku was a child, but what was Yoichi's excuse? Nana rolled her eyes.

Hisashi gasped. "One of my children reacted appropriately to foolish heroism for once?" He peered closely at Nana. She pretended to be asleep. "I saw that, princess. Clearly only you have the judgement to manage your foolish brothers. As I thought, you'll become my future heir. But first, your diaper change." He carried Nana away to her fate.


One bitterly humiliating diaper change later, Hisashi picked up Nana and rocked her. "What a fierce expression! I'm counting on you to become the heir to the Demon King's throne, my little princess. Dammit, villainy can't be completely recessive. At least one of my children must take after me. Yoichi won't let me turn Tomura into a villain. Izuku wants to become a hero, though I hope he'll grow out of it. And Yoichi has always been a lost cause. But you'll become Daddy's diabolical little villainess, won't you?"

Nana glared with a deadpan expression. Boy, are you ever barking up the wrong tree.

Hisashi held the baby up in the air and looked her directly in the eyes. "Lesson number one: dress style. A true villain wears bespoke suits, none of that hobo nonsense that has become popular with the younger villain crowd. Also, I don't wear ties as an act of rebellion, not because I don't know how to tie them."

No one believes you, Nana tried to say, but only baby babble emerged.

"Lesson number two: monologuing. Too many weak, pathetic villains get sneak attacked while babbling all their plans like morons. Instead, you should distract the heroes with a monologue while sending a minion to sneak up behind them. Remember that you do not have to monologue your real plan at the heroes. Villains lie!"

Nana shrieked, but Hisashi kept talking.

"Lesson number three: collateral damage is your friend! Many braindead, overly idealistic heroes can be easily lured into a trap by threatening civilians. That's how I killed an exceptionally foolish woman named Nana Shimura."

Howling, Nana kicked her arms and legs. She tried to spit at Hisashi, but it only dribbled down her chin.

Hisashi mopped up her face. "Lesson four: delegation. Villains can rely on the power of friendship, just like heroes. Why, my friends will even take care of my enemies without me needing to ask them."

Nana longed to make him stop talking. Could she fake unconsciousness? She closed her eyes and relaxed her head.

"Aw, my little villainess looks so angelic when she's sleeping." Hisashi kissed her forehead. "We'll go over the other five hundred lessons later. I need to repeat them as frequently as possible while you're a baby so the subliminal messaging will sink in."

Nana barely restrained herself from a cry of horror, knowing that if she revealed she was awake then the madness would start again.


Nana's crib had been piled high with stuffed animals portraying cartoon villains from popular children's TV shows. The baby rattle resembled a demon king's scepter. Two demonic bat wings protruded from her pacifier. A mobile decorated with skulls hung over her crib. Her walls had been painted bright pink, with a Darth Vader mural on the trim. A truly creepy baby doll with a cracked face and blood running from its eyes sat on top of her dresser. The bookshelf had been filled with picture books with villain-sympathetic titles like Dylan the Villain, The True Story of the Three Little Pigs as Told by A. Wolf, Darth Vader and Son, and Pilfer Academy. A plague hanging on her door read: "Knowledge is Power. Study Hard, Be Evil."

Hisashi certainly wasn't being subtle about his intentions. Nana wondered how he'd gotten Inko to go along with this décor.

Despite being covered with little Demon Kings, Nana's pillow was very comfy. She started to drift off for real.

The door opening jostled her awake. Yoichi poked his head into the room and sighed. "This is a travesty. The bastard is going to corrupt my niece. Baby sister. Same difference."

Nana groaned and tried to sit up. Her body wouldn't cooperate.

Yoichi stood on his tiptoes and peered into the crib. "Time to counter the evil brainwashing with hero lessons. Little sister, today I'll teach you why heroes always win."

Nana shuddered. She couldn't bear to endure this again.

Yoichi began, "Lesson number one: monologuing. Heroic monologues are naturally superior because they can turn enemies into allies by making them see the justice of your cause."

Nana had experienced Yoichi's monologues in the Void, and she knew they were only slightly less tedious than his older brother's. She'd sometimes wondered if All for One had turned into a villain because of his little brother's insufferable speeches. While stuck in the Void with Yoichi, she'd been nearly driven to evil herself. She howled. Although she'd intended to tell him to stop, only incoherent wails came out of her mouth. She had little control over her tiny body. Fat tears fell from her eyes.

"Shhhhh!" Yoichi waved his hands over her. "Mom will get mad at me."

A grown woman and former hero ought to have better control over herself. Nana imagined flying until her crying stopped. Then she strained to form words using her clumsy mouth. "F-f-first…"

Yoichi leapt backward. "How did you…" He took a closer look at her face. "Seventh?"

Nana nodded frantically. Her head hit her pillow, making tears form. She hated how easily this body cried.

"It's a very unfortunate situation," Yoichi agreed, stroking her cheek. "We're completely at the mercy of that dastardly villain. I wonder why this happened to you, too? Wait, it must be because Inko is your daughter."

"Ko-ko…" Nana tried to ask after her son.

Yoichi flinched. "That's a long and unfortunate story." He told her about how Tomura's quirk had run out of control and killed his family, finishing with, "I'm sorry."

Nana wept uncontrollably. Yoichi picked her up and hugged her. He murmured, "Hisashi wanted to turn Tomura into his successor, but I blackmailed him out of it. We'll keep him safe together. I promise."

Nana grumbled an incoherent insult.

"I know. He's unbearable." Yoichi sighed. "Welcome to living in hell."

"Yoichi Midoriya!" Inko stood in the doorway with her hands on her hips. "Did I just hear you threaten your baby sister? Did you make her cry?"

Yoichi paled. "No, Mom! I was joking!"

Inko took Nana away from him. "Go stand in the corner."

Head hanging, Yoichi left.

Inko rocked Nana. "Go back to sleep, Hana. I won't let the boys bug you again. I swear, Hisashi has been teaching them to bully their younger siblings. I'll have words with him later." Her face carved into a stone mask.

At least they had gotten All for One into trouble. Nana's mood brightened as she realized she had one advantage in this situation: she could torment her murderer without him being able to retaliate.


For the first months of her life, Nana could do nothing but howl at Hisashi while he repeatedly tried to teach her to become a villain. She had plenty of time to lie on her back and dream of revenge. Once she learned how to speak rudimentary words and crawl, she launched her plan.

While Inko dressed her in the morning, Nana shouted, "Shit!"

Inko dropped the sock in her hand. "Who taught you that word?"

Nana declared loudly, "Daddy said that Mommy's new haircut is shit!"

"Dear…" Inko growled.

Nana smirked, pleased to have driven a wedge between her daughter and her villainous husband.

In the doorway, Nana overhead the parents speaking indistinctly.

Hisashi cried, "I never said that! Mitsuki must have put her up to this!"

Afterward, Hisashi came into the bedroom. Nana flinched, afraid he'd be angry and keenly aware of their difference in size and strength.

Instead, Hisashi picked her up and spun her around. "What a clever revenge scheme, my little villainess. Did you get angry at Daddy because he wouldn't let you have ice cream with the boys? You're too young for it, but I like your greed." He kissed her forehead. "Your first evil plot to frame someone else! I'm proud of you!"

Nana groaned. What was the point if All for One didn't get angry?


Nana launched her next scheme over dinner as the family planned her first birthday.

"What would you like for your birthday, sweetie?" Inko asked in a sing-song tone, clearly not expecting a coherent answer.

Nana took a deep breath and spoke as clearly as she could. "I want All Might to be my dad!"

Hisashi choked on his soup.

Inko frowned. "That's a little tricky. Maybe I could hire an All Might impersonator?"

Nana smirked. "I want Dad to dress up as All Might."

"I think she said she wanted me to dress up as a demon king," Hisashi said.

Inko sighed. "Dear, I know how you feel about heroes, but this is the only thing she asked for. Please, do it for me."

Izuku clapped his hands. "What a great idea! I want Dad to dress up like All Might for all my future birthdays!"

"Me, too," Yoichi said spitefully. "Great idea, Nana…err, Hana."

Hisashi looked like he was being dragged off to Tartarus.

Tomura rolled his eyes. "Everyone in the family has such bad taste in heroes. I want a matching father-son Eraserhead cosplay."

Nana whispered to Yoichi, "I'm counting on you to get blackmail pictures."

"I already stole a camera," he whispered back.


Emboldened by her success, Nana next plotted a more elaborate scheme. Yoichi agreed to take off all his clothes and streak around the house as a distraction. While the parents chased after him, Nana snuck into Hisashi's bedroom with a lighter.

"Why do I smell burning?" Hisashi grumbled. He opened the door to find Nana standing over his flaming closet. Flames rose off his beloved bespoke suits.

Holding up the lighter, Nana grinned. "Daddy, I'm a cave man! I make fire!"

A blast of water shot from Hisashi's palm, extinguishing the fire. He leapt forward and scooped up Nana. "Are you hurt, little villainess? Does anywhere feel ouchie?" He looked her over. "You didn't even singe yourself during your first ever destruction of property. You're a natural arsonist."

Nana scowled. His lack of anger had ruined her fun.

Hisashi hugged her, rubbing their cheeks together. "Excellent attempt for a young villain. But I haven't kept any of my good suits in the house since your youngest brother went through his terrible twos."

Nana groaned.

Hisashi chuckled. "I knew you were the child who would become my evil heir. You're a perfect little villainess. Let's go over the lessons again."

In her desperation to avoid this fate, Nana shouted, "Big brother Yoichi provided the distraction!"

"You even learned to shift the blame and use other people as patsies." Hisashi wiped a tear from his eye. "I'm so proud. You may look like your mother, but you have your father's blood flowing through you. Lesson number one hundred: good looks do not make the villain, but they help you get away with crimes. I splurge on my haircut, because a little vanity is good for evil."

Nana sobbed for real.


Nana's next shot at revenge came on her father's birthday.

Nana sat in Hisashi's lap, entirely against her will. She took the opportunity to kick him in the shins a few times.

Inko brought out a chocolate cake covered in candles. Nana pointed at them. "Daddy old!"

Chuckling, Inko said, "I'm sure he must seem old to you, sweetie."

Far older than you know, Nana thought. That creepy old man should stay away from my daughter.

Yoichi shifted on the sofa between Izuku and Tomura. "Hurry up and blow out the candles, old man."

Hisashi beamed. "Aw, you finally called me Dad!"

Scowling, Yoichi glared. "I called you old man because you're literally old."

Nana pointed. "Daddy white-haired! Daddy ancient! Daddy is a corpse." She clapped her hands.

"She learned a new word, how cute." Hisashi whispered in Nana's ear, "Your daddy has an army of corpses. Villain lesson number eighty-eight: the people you murder are a reusable resource."

Sighing, Inko set down the cake. "I thought we'd have at least a decade before the teenage rebellion started."

Nana immediately pasted a smile on her face, because she didn't want to trouble her daughter. Mother? Daughter? "Cake smells good, Mommy."

Hisashi blew out the candles. Then a war started wherein Hisashi tried to feed Nana cake, and Nana tried to spill it on his nice pants. After the cake crumbs started floating just above his pants, she realized he was using a quirk. Foiled again. (Wait, was that a villain thing to think? Was he corrupting her?)

A pile of birthday presents overflowed from the coffee table to the floor underneath. Hisashi picked a round gift in green paper.

"That's from me," Tomura said.

Hisashi pulled off the paper to reveal a dog collar. The look on his face said it all.

Tomura said, "That's for the new dog we're getting."

Hisashi's eye twitched. "I already told you no. I don't like dogs."

"But now we have a collar, so we have to get a dog," Tomura said with impeccable child logic. He pulled out a hidden folder from behind his back. "Just look at all these corgis in need of a good home." He dumped photos over his father's lap. "Can you say no to those big, cute eyes?"

Nana grinned. Her grandson was a natural at tormenting All for One, even without trying. Naturally, she decided to help him. "Puppy! I want puppy!"

Yoichi coughed. "The Bakugos have a new hamster…imagine how we would show them up if we got a predator for a pet…"

Competitiveness warred with irritation on Hisashi's face.

Izuku struck the fatal blow. "Kacchan said that Aunt Mitsuki wouldn't let him get a dog because it was too expensive. If we don't even have a hamster, does that mean we're poor?"

"Of course not," Hisashi growled. "Fine. Tomura, I appreciate your evil but I expect you to give me a makeup present that isn't actually for yourself."

The children cheered.

Next, Izuku gave his father an All Might mug. Tomura decayed the mug and declared that to be his present for his father, only to be promptly drowned in a flood of tears from Izuku.

Inko handed Hisashi a present wrapped in blue and white stripped paper. "This is from me and Nana. She picked it out of a catalogue for you."

"How, sweet, my first gift from my daughter—" Hisashi pulled open the box to reveal a clip-on tie. The smile dropped off his face.

Yoichi said brightly, "Now you'll finally be able to wear them without accidentally hanging yourself."

Nana smirked. When she realized that Hisashi was looking directly at her, she schooled her expression into innocence. She couldn't afford to give herself away.

Hisashi hugged Nana. "I love it. Thank you."

She gaped, trying to figure out if he was lying.

A tear falling from his eye, Hisashi cried, "All I wanted for my birthday was for my daughter to be evil. You figured out my greatest weakness and mocked it! You've inherited my diabolical manipulation skills."

Nana and Yoichi exchanged despairing glances. Why was it so hard to torment Hisashi? Did nothing annoy him?

Hisashi attempted to fasten on his new clip-on tie. The tie somehow ended up wrapped completely around his neck.

Nana saw her chance. She grabbed the end of the tie with all her might, yanking. Hisashi gasped for air. His face purpled.

"I'll save you, Daddy!" Izuku leapt forward, waving his Samurai All Might figurine. He used the sword to cut the tie.

Tomura immediately jumped on the tie fragments and decayed them. "I got the glitch!"

"All Might rescued Daddy!" Izuku declared proudly.

"Maybe All Might isn't so bad," Tomura admitted. The two brothers reconciled from their earlier fight with a fist-bump.

Lying cross-eyed in the armchair, Hisashi muttered, "All of history since the dawn of the age of quirks flashed before my eyes…"

Inko sighed. "It appears that you and ties aren't meant to be, dear. I think you look charming in bowties."


Mitsuki sailed into the house and kissed Inko on the cheek, then kissed Nana's head. "Aw, your little accident is much cuter than mine. I wanted a girl instead of another boy."

Inko gasped. "Mitsuki! I told you to stop calling Hana an accident in front of her!"

"She doesn't understand me," Mitsuki said, making a funny face at Nana.

Nana giggled. She always enjoyed it when Mitsuki visited, because Hisashi hated his wife's friend with a passion he normally reserved for heroes and ties.

Katsuki followed after his mother. "I heard the nerd got a new All Might figurine. Where is it?"

Behind him, a kindergartner with spikey brown hair growled, "Big brother, what did I tell you about insulting people?"

Katsuki hung his head. "You said that our family insulted each other to show love, but that was because we were all goddamn dysfunctional, and I should give my friends nice nicknames or none at all."

"That's right. Very good." The spikey-haired boy stood on his tiptoes to pat Katsuki on the head. "Izuku is upstairs."

As Katsuki ran off, he passed Yoichi coming down the stairs. Inko placed Nana into Yoichi's arms. "Can you and Kaiji play in the living room while I have tea with Aunt Mitsuki?"

"Yes, Mom." Yoichi carried Nana into the living room.

As soon as the door shut, Nana cried, "Second! It's good to see you!" She toddled over and hugged him. Nana had been surprised but greatly pleased that Second had reincarnated into the family of Inko's best friend. After being treated like a baby all day, she desperately wanted to talk to someone who knew her as an adult. Yoichi helped, but Yoichi talked about heroes way too much. Even a former hero like Nana got sick of it.

Yoichi demanded, "How did you tame your older brother? I must know your secrets!"

A tiny flame danced on the spikey-haired boy's tongue. Second said, "Beat him until he stops moving or becomes obedient, whichever happens first."

Yoichi collapsed to his hands and knees in despair. "Unfortunately, my brother is stronger than me."

Second patted his back. "We can gang up on All for One together. Today is the day that our plan comes to fruition."

A month ago, Nana had distracted Hisashi by pretending to listen to his villain lessons while Yoichi and Second snuck into his office. They'd stolen documents and mailed them to Japan's National Tax Agency, calling down an audit. Supposedly the audit would be finished today.

Adult footsteps came down the stairs. All three reincarnated children pressed their ears to the door, hoping to hear what Hisashi had to say.

Mitsuki snorted. "Hisashi. Gossip on the street says that you got in a fight with a tie and lost."

Hisashi growled, "Mitsuki. I heard that your head was impaled with spikes but it looks like that was just your hair."

Inko sighed. "Really, you two…dear, what happened with the audit?"

Hisashi laughed. "I'm proud to say that after extensive examination, the National Tax Agency found that they owe me a refund on last year's taxes. I'll take the whole family out to dinner tonight."

"How wonderful," Inko said.

Nana didn't hear the rest of the conversation, because she fell on her back, moaning. "This is unfair!"

"I was certain they'd find something," Yoichi said. "My brother lies and cheat on everything."

Second sighed. "Maybe he bribed the auditor?"

The door opened, and all three children leapt backward. Second and Yoichi successfully hid behind the sofa. Nana wasn't fast enough.

Hisashi scooped Nana up in his arms. "Time for villain lesson number forty-two: the only two certainties in life are death and taxes. I may have thwarted death to obtain immortality and construct my army of Nomu, but I never, ever mess with the tax collectors. I know when I'm outmatched in evil."

Nana groaned. They probably should have checked more carefully for evidence of tax evasion before sending the letter. But who would have guessed All for One would pay his taxes?

Izuku ran into the living room. "Dad, did you say we're going out to dinner?"

"That's right, ducky." Hisashi ruffled his son's curls. "Your clever father separated the most evil beings in existence from their money."

"Whoa, you're cool." Izuku beamed. "Did you make a lot of money?"

"I received a refund of over a million yen."

"Then you must have enough money to take us all out to the new All Might movie after dinner."

Hisashi's smile froze. "Was there yet another movie?"

Izuku looked down and scuffed his feet on the carpet. "Kacchan has been bragging about getting to see an early screening. He said that Aunt Mitsuki used special connections to get tickets. It's a shame our family doesn't have any special connections…"

"Oh, really?" Holding Nana tucked under one arm, Hisashi pulled out his phone and texted. "It looks like there's an extended edition screening in limited theatres. It come with an autographed All Might keychain as a souvenir. The theatre owner owes me a favor."

"Yay! Daddy is the best!" Izuku jumped up and down and cheered.

As soon as they were alone, Second crawled out from behind the sofa. "Funny, Katsuki complained to me that he couldn't get tickets to the All Might movie. They were sold out all over town."

Yoichi said, "Izuku has a knack for manipulating my big brother."

Nana said approvingly, "My cute Izuku has a knack for tormenting All for One that I've never seen in anyone except you, Second. Or maybe Third. Are we sure that Izuku isn't Third? He could have lost his memories."

"Quite sure. I met Third in kindergarten," Second said. "He's part of a family called the Kirishimas."


Nana successfully fooled Hisashi into thinking she was a normal baby (or perhaps he fooled himself) until shortly after her second birthday. With a lack of intelligent conversation (Yoichi didn't count), she got desperate. She stole her mother's phone and sent an anonymous email to Gran Torino tipping him off about the location of Inko Midoriya formerly Shimura, and revealing that All for One had married her. That would definitely send Torino running over, but subtly to avoid being noticed by the villain. Hopefully then Nana could find a moment to reveal her identity. She successfully returned the phone.

Hisashi, of course, had a tap on every phone in the family.


Standing in the grocery store, Inko contemplated between generic and brand name soy sauce. Her husband oozed money from his pores, but she had never got quite out of the habit of saving money from her youth as an orphan. Also, she wasn't convinced that brand name soy sauce tasted any better.

A short old man bumped into her grocery cart. He leapt backward, crying, "The furniture has finally revolted! It's every man for himself!" He fell to one knee.

Inko ran over to help him up. "Sir, are you all right?" She looked around, hoping to find someone accompanying this senile old man.

He peered up at her. "Nana! I always told you that someday our carts would tire of bearing our burdens and rise up against us. But you called me mad! Ha!"

"My name isn't Nana. I'm Inko Midoriya. Is your Nana around here?" Inko did not see anyone else in the aisle. She handed over his cane.

"Don't you recognize me, Nana? It's Sorahiko Torino. Or you can call me Gran like you used to." He chuckled. "Is your memory going? Have you gone senile?"

The name Gran Torino rang a distant bell in Inko's mind. "Are you a hero? Or did you used to be a hero?"

Torino beamed. "We were great heroes together! See, let me show you a picture." He pulled open his wallet to reveal a younger version of himself with his arm around a dark-haired Amazonian beauty.

"She looks a lot like me, if only I was tall," Inko muttered.

Torino said, "I was even the godfather to your only daughter, Inko. I miss her so dearly, ever since you died and she went into foster care under a false name to escape a villain targeting us." He pulled out another photo of Nana holding a baby girl, then paperwork showing the girl's name being changed from Inko Shimura to Inko Midoriya. "I think I came here looking for her…but I don't remember."

It was very suspiciously convenient that the supposedly senile man had all this evidence on hand to immediately show her. However, Inko was too thrilled to be suspicious. Like most orphans, she'd secretly dreamed that she had a romantic tragic past. "Oh! Sir, I believe you were looking for me. My name is Inko Midoriya." Her husband had taken her last name, saying that he had no attachment to his. She was now glad of it, because she could show Torino her driver's license.

"My goddaughter!" He hugged her.

"I'm so happy to finally meet my family!" Inko hugged him back. "I'll take you home and introduce you to my children."

"I can't wait to meet my new grandchildren," Torino said with a gleam in his eye.


Nana sat on the living room rug, playing with Izuku. Her grandchild/second oldest brother (boy, was that strange) had an extensive collection of All Might merchandise which allowed her to keep tabs on the hero career of successor she'd loved as a son. Even better, Izuku was an endless fount of All Might trivia.

Izuku held up a figurine wearing at a purple cape. "This is All Might from his first debut. Everyone agrees that the purple cape was a mistake, but luckily he changed it in two months."

"Grape!" Nana cried, pointing. If only she'd been alive, she never would have let Toshinori wear that monstrosity. Her dear boy never had much fashion sense. Hopefully now he was in the hands of a publicity team.

Izuku held up two more figurines. "Here we have All Might with his sidekick, Sir Nighteye."

"Smart?" Nana asked, determined to find out if this sidekick was good enough for her boy.

"Oh, yes, Sir Nighteye has a brilliant tactical mind. He runs his own hero agency now. He has a future seeing quirk. I'm not sure the limits of his quirk. Heroes tend to keep information about their powers under wraps, for fear of villains."

If someone had told Nana that her future would involve becoming All for One's daughter, she never would have believed it. "All Might alone?" she asked, more preoccupied with her successor.

"All Might has a large support team but he does tend to work alone," Izuku said. "Most heroes simply can't keep up with the versatility of his quirk." This launched Izuku into his standard hour-long lecture on the greatness of All Might's quirk, which Nana soaked up with pride since it was her quirk, too. It had certainly stockpiled more power over the years.

From the front step, Inko called, "Could someone please open the door? My hands are full of groceries."

"Coming, dear." Hisashi shot down the hallway and opened the door.

Gran Torino stood next to Inko, looking slightly more withered but every bit as fierce as the last time that Nana had seen him. "The taxman!" he cried and immediately kicked Hisashi in the face.

Hisashi reeled backward. A gust of wind caught him before he hit the floor. His neck muscles strained, probably with the effort of holding back from using all his quirks in front of his family. He protested, "I'm evil but not that evil!"

Nana slapped her forehead. Why had she possibly imagined that Gran Torino would be subtle about how he approached her family? Subtlety had never been either of their strong suits. Also, didn't anyone ever teach her daughter not to bring strange men home? Nope, apparently not. That one was on Nana.

Torino whacked Hisashi across the neck with his cane. "You won't get my moonshine, you government dog! Ha! I have vanquished the fiend!"

"Stop, Torino." Inko grabbed his arm. "This is my husband, Hisashi." In a lower voice, she whispered, "Please forgive him, he's gone a little senile." Inko radiated hopefulness and desire to make this meeting go smoothly through sheer force of will.

Torino peered up at Hisashi. "You certainly picked an ugly one! Or perhaps anyone would look like a beast next to Inko's beauty."

"You're too kind," Inko trilled.

"Who is this?" Hisashi sneered. "A beggar you dragged home out of pity?"

"Hisashi, be polite! This is my long-lost godfather, Gran Torino." Inko put an arm around him. "He's going to be the children's grandfather from now on."

Hisashi growled, "He most certainly is not—"

Torino snapped his fingers. "I know who you remind me of! A nasty, nasty villain who I fought many years ago. I had the bastard beaten, but I let him go because he had a civilian family. If anything ever happened to me, then information about his true identity would be sent to his wife."

Hisashi's face turned red, then purple.

In a tone that could be interpreted as a threat, Inko said, "I'm sure you two will get along once you become better acquainted. Help me carry these grocery bags into the kitchen."

Both Hisashi and Torino took bags. As Torino passed Nana in the hallway, he smiled down at her. "This is your daughter?"

Inko said, "Yes, this is my youngest, Hana."

"Hi." Nana stared at Torino, trying to convey her true identity with sheer force of best friend telepathy.

Torino said, "My, she's the spitting image of her late grandmother! It's a pity she's not quite as pretty, though. If you keep making that sour expression then your face might freeze like that."

Nana kicked him in the shins.

From the kitchen, Hisashi called, "That's Daddy's girl! Avenge me!"


Gran Torino stayed for dinner. As soon as Izuku found out that the old hero had once mentored All Might, he exploded with questions. The meal turned into a long All Might story session, which only made Hisashi's face become increasingly sour. Tomura looked no more thrilled and excused himself early. Unfortunately Nana had never been able to completely cure Tomura of his All Might dislike, although without Hisashi brainwashing him, Tomura's dislike had turned into less a rabid hatred and more annoyance that his little brother never shut up about the number one hero.

Nana could only talk with a toddler's vocabulary at the dining room table, so she had no more chances to communicate with Torino. After dinner, Torino and Hisashi competed to help Inko clear the dishes. Nana hopped down from her high chair and hissed, "I need a distraction."

"I'm on it." Yoichi sailed up the stairs. Minutes later, Hisashi shouted, "Yoichi has a lighter again!" Inko immediately came running.

Nana found Torino alone in the kitchen, rinsing dishes. She hissed, "Gran! I'm the one who sent the email to you!"

Torino looked down at the pink-cheeked toddler. His eyes narrowed, the senility dropping off his face to be replaced by an intense assessment.

"It's me, your old drinking and villain-bashing buddy, Nana Shimura. I reincarnated." Nana had planned out how to make him believe her. "Who else knows about that time you got drunk and admitted that your birth name was Gran and you changed it out of embarrassment?"

Torino stared. "I destroyed all records of that. Oh my god. You're Nana."

She leapt forward and he caught her. They stayed like that, with her arms wrapped around his neck. Nana pretended not to see Torino crying. She might have shed a tear or two herself.

Into his shoulder, Nana mumbled, "Wow, you aged badly. Look at you! You're a tiny troll!" She had not forgotten his dig at her looks.

Torino said, "At least I managed to stay alive. Also…I'm taller than you now."

Nana groaned. "I oughta slug you!"

Torino smirked. "You can't hit me! I'm the elderly, and you have to respect your elders, little girl."

"You may be old, but you know what I am?"

"What?"

"A toddler." She gave him a wet willy.

"Like you didn't do that to me as an adult." He laughed.

Nana stuck out her tongue.

Sobering, Torino asked, "Can I tell Toshi?"

Nana looked at her childish red shoes, painted with devil's horns by her father. "I don't know how he'd react."

"He'd love to see you again."

"I'm All for One's daughter."

"Toshi hates All for One because he murdered you. He'd let go of a lot of his hatred if he could see you alive, which might be good for him. You should see how Toshi has been running himself ragged looking for All for One. He's convinced the villain has some dastardly scheme planned. He'd be frankly relieved to find out that All for One settled down with a large family instead." Torino brushed back a lock of her hair. "This is your choice. I won't force it. But Toshi wouldn't care if you turned into an ugly toddler or the daughter of his enemy. He wants to see you again."

"I want to see him again, too." Nana swallowed a lump in her throat. "I…give me a few days to think about it. I need to work up the nerve. Besides, All Might must be a very busy hero. I'm sure he has too much to do to rush over here."

A child's voice cried, "All Might is coming to our home?" Izuku stood in the doorway with his eyes gleaming.

Nana whirled around. "That's…we weren't serious. We were only playing."

"I'm going to meet All Might and get all my merch autographed!" Izuku turned and ran up the stairs. Distantly, he shouted, "Big brother, All Might is coming!" Tomura's anguished screams could be heard drifting down the stairs.

Nana sighed. She couldn't bring herself to disappoint Izuku. That meant she would have to act her real age and face her successor.

To make this future meeting even worse, Toshi had gotten taller than her too. At least he wasn't likely to mock her about it.


Hisashi stopped by Nana's bedroom shortly after Torino left. "Nana Shimura, eh? I suppose this is what I get for not doing a background check on my wife until after we were engaged. If I'd realized sooner that Inko was your daughter…well, I wouldn't have done anything differently, since I'm quite happy with my current life."

Nana's creepy baby doll slipped from her hand. She paled, not sure what question to ask first. "You…know? How?"

Hisashi shrugged. "Obviously I had my quirks eavesdropping on everything Torino said or did while in my house." He crouched down on carpet next to Nana. "Given your advanced vocabulary, I should have realized sooner that the reincarnation quirk was still in effect. I just assumed you were a genius like your dad. Though you are brilliant to have evaded me so long."

"Reincarnation quirk?"

"I planned to use Izuku as my replacement for Yoichi, but Inko convinced me that would be extremely unhealthy. So I found a quirk to get myself the real Yoichi instead." Hisashi beamed, clearly impressed at his own cleverness. "The quirk causes the user to reincarnate their deceased relatives as their children. The previous holder was tired of being mistaken as quirkless and already had as many children as she wanted, so she traded her quirk to me."

Whoa. Nana didn't know where to begin unpacking that insanity. She backed away from her current father until her back hit the wall. "What will you do with me?" she asked, prepared to scream for Inko.

Hisashi tilted his head. "On the one hand, I hated your past self…but you're family now, so let's put that behind us! Since you've been deliberately trying to drive me insane, I can only assume your rebirth caused you to inherit my scheming ways. You're still my best bet for raising up a villainous successor!"

Nana's eyes narrowed. "Hard pass."

"Why? It's not like you were any good as a hero. That life got you killed."

"Because YOU killed me!"

"Details, details, my little villainess. We were going to let the past remain in the past."

"You said that, not me!"

Hisashi ignored her protests. "You're clearly far more gifted in villainy than heroism. It's also a much safer path, with me providing you with an entire empire as a starter kit. If you went into a dangerous path like heroism, I'd be forced to take drastic measures."

Nana stared wearily. "You've already got a vault picked out, don't you?"

Hisashi beamed. "Painted pink with princess dolls and loads of villain books to brainwash you! But that's only if I need to put you in there."

Nana groaned. "I hate you."

Hisashi laughed. "Awww, that's cute. I'll cut you the same deal as Yoichi: if you refrain from causing more property destruction, then I'll let you watch R-rated movies. If you tell Inko, then you'll be eighteen before you see any film that doesn't have a talking animal in it."

Nana sighed. "…Let me see Torino and Toshi, and you have a deal."


OMAKE TIME!

Omake: Why Hisashi Didn't Get His Face Ripped Off

Hisashi: Doctor, I need you to give me a vasectomy. Kill my swimmers completely dead. I don't want to chance bringing all my mortal enemies back to life.

Dr. Garaki: But you aren't related to any other vestiges.

Hisashi: I'm more worried about reincarnating my parents next. Believe it or not, I hate both of them significantly more than Nana Shimura. Also, they'd have awkward questions about who cut the brake lines on their car.

Doctor Garaki: What little professional ethics I have compels me to tell you that vasectomies don't have a hundred percent effectiveness rate.

Hisashi: Ugh, how can I risk killing All Might now? Nana considers him like an adopted son! The risk of him coming back as my kid is far too great!

#

Omake: Canon Averted

Dr. Garaki: Master, I feel like we've been making less progress with our intended conquest of Japan.

Hisashi: Look, I can either take over the world or control Nana. I can't do both.

#

Omake: Name Game

Hisashi: Let's name our new baby Yoichi.

Inko: …Dear, the doctor said we're having a girl.

Hisashi: Yoichina?

Inko: We already have a child named Yoichi.

Hisashi: But I need another, more malleable Yoichi to live out my fantasies of turning her into a villain!

Inko: Why don't we let Tomura name our daughter? You said your family had a tradition of letting the older sibling name the younger one. I think that would be a lovely way to save our unborn daughter from being mocked for her name forever.

#

Omake: That's the End of That

Hisashi: Where is Nana?

Inko: Do you mean Hana? I know you're bad with names, but I expect you to remember the name of your own daughter.

Hisashi: I've been thinking, could we change her name to Nana so it's less confusing for me?

Inko: Are. You. High?

#

Omake: If Hisashi Finds Out About Second

Second: I'm here for a sleepover. My mom is friends with your wife, so you can't kill me.

Hisashi: What did I ever do to deserve having the brother thief invading my home?

Nana and Yoichi: (Open their mouths.)

Hisashi: That was a rhetorical question.

#

Omake: Nana's Quirk

Nana: (Grabs Hisashi's arm) I refuse to go to bed!

Hisashi: Come back, my little villainess, you need your rest. Wait, are you floating?

Nana: …

Hisashi: Your quirk came in! Hey, why can't I fly any longer?

Nana: …

Hisashi: You got All for One, just like your daddy. I knew you'd become my successor.

Nana: Hold up! If I just stole Float from you, then that means you stole my quirk before I died!

Hisashi: Oh no, my doctor helped me pry Float from your mangled corpse.

Nana: …

Hisashi: Then I chopped off your hand as a souvenir and gave it to your grandson to wear on his head.

#

Omake: A Quirk for Everything

Nana: Inko Shimura! I look away for one second, okay thirty years give or take, and I catch you hanging around with boys like All for One? I would SO ground you if I could speak and you didn't have the power to also ground me!

Hisashi: Honey, look, our daughter is babbling and making faces at you. I wish I had a quirk to speak baby.

#

Omake: Mom Versus Mom

Inko: I gave birth to you, I breastfed you, I changed your diapers—

Nana: Last I checked, I did all that stuff for you, too!

Inko: Raised you?

Nana: …Touché.

#

Omake: If Tomura Finds out the Truth

Tomura: I'm just going to pretend that's not a thing and play video games. You get back to those calibrations or whatever.

Nana: I'm not a side character!

Tomura: You're a backstory character DLCed in. Or a really weird mod.

Nana: Hey! I'll have you know I'd be a good mod!

#

Omake: Nana Gets to Taste Yoichi's Pain

Nana: I feel dirty after All for One praised me for being evil, I need to be cleaned.

Hisashi: Is it time for your next diaper change, princess?

Nana: I TAKE IT BACK!

#

Omake: The Distant Future

Izuku: My father is All for One. This both means that he's a supervillain, and that he could have given me a quirk but didn't. Time to commit patricide.

Nana and Yoichi: YES! FINALLY! TIME TO KILL THAT SCUMBAG!

Tomura: How am I the only normal one in this family? As the only one with personal experience in patricide, I must say that murdering your father isn't as much fun as it might first appear.

Izuku: Take that back!


Author's Note: Credit goes to Gfan97 for coming up with many of the plots used against All for One and the last six omakes. Gfan97 practically deserves coauthor credit for this one. I bow to you, my sensei in tormenting Nana. Seriously, everyone should check out the "Nana Shimura vs All for One: The Battle of the Christmas Dinner!" and all the sequels. They're wonderfully cracky.

Hisashi probably won't have much luck turning Nana into a villain, but she's never getting rid of him now he's decided that she's family.
