Chapter 1: A Stranger Returns

In a dimly lit room, Hiashi Midoriya, the infamous villain known as All for One, stared into the darkness, reflecting on his past actions. As the leader of the Japanese criminal underworld, he had made countless ruthless decisions and crushed many heroes who dared to stand against him. Despite his past life, Hiashi could not shake off the lingering memories of his lost family.

His wife, Inko, and his estranged son, Izuku were the only threads that kept his humanity intact. As time passed, the thought of his family never having the chance to live a peaceful life tugged at his heart. Hiashi made a decision that would change his life forever; it was time for him to retire.

With the help of his loyal servant, Dr. Kyudai Garukai, Hiashi underwent numerous surgeries to repair his face and heal his body. Slowly, he started shedding away the remnants of the villainous life he once led. When the time was right, he devised a plan to bring his family together again.

It had been several years since Hiashi had set foot in his old home. Inko, his wife, was cautiously welcoming to her husband, with slight disbelief in her eyes. Even so, she was more than willing to give him a chance to become a part of their family again.

Their reunion began with Hiashi relating the tale of how he came across a young girl named Eri, whom he claimed to have been a street child in dire need of help. Moved by the girl's plight, he decided to adopt her as his daughter. As they both listened intently, Inko grew fonder of Eri, treating her as the daughter she never had.

Unbeknownst to either Inko or their son, Izuku Midoriya, the shy and reclusive Eri was actually one of Hiashi's younger daughters from the many other wives, lovers and one-night stands he had under his various aliases. Hiashi had in fact rescued the poor girl from the clutches of the Shie Hassaikai [1], a branch of the Yakuza that was aiming to rule the criminal underworld in the wake of Hiashi's defeat by All Might under his alias of All for One when Izuku was just a young boy.

Hiashi had of course slaughtered all of the Yakuza members and taken the Quirk of its leader Kai Chisaki, before using his hand-to-hand skills to tear the man apart from limb to limb.

Not in front of Eri of course. All the scared, silver-haired little girl ever knew was that she had been rescued from those mean men who were after her due to her incredible powers by her previously absent dad, who had never been in her life before but had somehow appeared just as she was in trouble to come and take her from her life of misery.

And all the police and Pro Heroes ever knew when an investigation was eventually launched into the matter, was that a local fraternal association had disappeared completely off the map. Since the self-proclaimed "Overhaul" had been smart enough not to be seen with Eri when he had been using her to make anti-Quirk bullets and the so-called Eight Precepts of Death hadn't even made any moves in the underworld before Hiashi struck, the whole thing was dismissed as a cold case and quickly forgotten.

As for Izuku, adjusting to his father's sudden reappearance in his life was a bit of a shock. Izuku, who was always skeptical of his father's absence, was now faced with the reality of having him back in his life. Even so, he also tried his best to be a loving older brother to Eri, helping her acclimate to the Midoriya family.

Over time, the bond between Izuku and Eri grew stronger, with Eri developing feelings for her older brother that went beyond simple sibling affection. [9]

Due to certain circumstances, Izuku never got the chance to attend U.A. High School to become a hero. Instead, he decided to utilize his intelligence to help the Hero Community indirectly. Izuku worked tirelessly on providing schematics and designs for specialized hero gear, making a significant impact on the community. Despite not fulfilling his dream of becoming a hero, Izuku remained proud and dedicated to his work.

A loud knock interrupted the calm afternoon at the Midoriya residence. Katsuki Bakugo, Izuku's former childhood friend and now a U.A. student, arrived to confront Izuku about his rumored success. He had come to settle the score with his old friend, who had supposedly outshined him after having disappeared from his life.

Bakugo's impatience got the better of him, and he kicked the door open with anger, barging into the Midoriya residence. However, the scene that unfolded before him left him completely dumbstruck.

"What...the fuck?" The hotheaded blonde couldn't say anything else as his red eyes bore witness to what was going on in front of him, one moment he was beating down on the Quirkless loser for daring to be a Pro Hero despite his status, and then just as everyone at Aldera Junior is about to graduate/move up in classes, the fucking nerd disappears and Auntie Inko moves out of Mustafu to live in this high-class area.

Bakugo had to use his contacts at UA to even find out where the fucking nerd was, and the worst part is he had to sneak in due to the number of armed guards and private security swarming the area. He had done all of this, and possibly ruined his hero career forever if he was ever seen by the fucking nerd or the guards around the area, only to see this. The short-fused blonde wondered if he was going insane due to all the small-time villain cases 1-A had been picking up these days.

What was the reason for this, you might ask? Well, it was all due to what Katsuki Bakugo had the utmost misfortune to stumble upon.

There in the living room, Eri was in the midst of kissing Izuku on the lips, overwhelmed with joy after confessing her deep love for her beloved onii-chan. Katsuki Bakugo, who fully expected to find the timid and cowering 'Deku' he once knew, was now faced with a scene beyond his comprehension.

Before any of them could notice his presence, Bakugo was sent flying out of the house by an unknown force, blood gushing from his nostrils in shock. Meanwhile, Eri continued showering Izuku with affection, while Izuku remained at a loss, uncertain of how to process his sister's newfound feelings.

Little did they all know, this marked the beginning of a new path for the Midoriya family, one filled with unexpected revelations, rediscovered bonds, and the lingering shadow of Hiashi's past life.

For Izuku Midoriya, life had become a much more complex juggling act than before. The recent revival of his relationship with his father and the development of Eri's feelings towards him had occupied much of his thoughts. However, he was determined to continue making a difference in the world in any way he could.

A call from U.A. High School's principal, Nezu, offered him the perfect opportunity to showcase his work on specialized hero gears. Izuku accepted the invitation, eager to contribute to the heroes-in-training, but worried about keeping his 'quirkless' status and the existence of his younger sister hidden from the curious minds at the prestigious school.

Upon arriving at U.A., Izuku was met with praise and admiration, something he wasn't accustomed to receiving. However, his anxieties peaked when Midnight, the pro-hero known for her seductive charm, mentioned how Shoko Todoroki, the daughter of the number one hero Endeavor and a U.A. student, had recently triumphed over Bakugo in the sports festival using gear designed by Izuku.

Suddenly, the voice of his little sister Eri rang out through the air, cheering for her older brother from the sidelines. At that moment, Izuku found himself torn between a mixture of appreciation, embarrassment, and the fear of his secrets being exposed.

This open, natural and healthy display of affection by a little sister for her loving big brother, of course, caused the hot-headed pomeranian known as Katsuki Bakugo to lose it and forget that he was at the closing ceremony of the Sports Festival and thus was on live TV for the whole of the Japanese People's Republic [2] and the entire world to see, and bellow out in a rage-filled tone, causing his classmates and form teacher Eraserhead to jump back in surprise and shame: "NO FUCKING WAY! This can't be real! I must be going insane!

First, that fucking Quirkless Deku drops out of school just as everyone is about to graduate and Auntie Inko then moves out of the neighborhood to live in some ultra-exclusive private gated community, then when I come to investigate and show that goddamned nerd his fucking place in the pecking scale, I realize that fucking Deku is living the good life in a fucking castle that looks like something you'd see in a storybook, and that the real reason why he became a middle school dropout was so that he could enjoy his new life of wealth and luxury without worrying about us ordinary peons, and also to indulge in his hidden desires as a lolicon and lover of younger girls!"

Katsuki's outburst had not only the whole of 1-A, but every hero in Japan bowing their heads in shame and disgrace. Even the villains of Hiashi's front organization for fighting the nefarious Meta Liberation Army and the MLA's minions in the bought and paid for Hero Commission, the League [3], were shocked, embarrassed and disgusted by how callous, racist and elitist this supposed hero in training was, and how open and blatant this outright bully was with his bigotry. Towards a Quirkless person, nonetheless.

"It was so fucking infuriating, having to be trapped in jail like some common criminal for breaking, entering and trespassing when in reality, all I was doing was just showing my inferior his place behind me! And you won't imagine how embarrassing it was to be trying to tell the police that Deku and his little girlfriend, who had to be fresh out of elementary school and that's the oldest I think she is, were engaged in a full-scale make-out session without a fucking care in the world and the fucking worthless boys in blue almost have me thrown in a mental asylum because I was supposedly engaged in 'defamation of the Midoriya family and making unproven statements about the children of Hiashi-san and Inko-hime'."

From his command center at one of his many hideouts, Hiashi clenched his fists and struggled to control All for One as he listened to this self-righteous jackass, who was the son of his beloved Inko's best friend and Izuku's childhood friend as well to make matters worse, degrade and insult his only son and one of his precious daughters for the entire world to see.

Hiashi wasn't stupid despite his years, he knew that Eri saw Izuku as more than a brother and he and Inko had even secretly encouraged her affections towards Izuku in the hopes of getting grandchildren soon, but not too soon of course, but for this spoiled piece of shit whose never had to suffer even a day in his pampered life to go on air, in front of the world and make such a bigoted, cruel and insane speech confirmed Hiashi's long-held suspicion that the superhuman society created by Quirks was rotten, and the Meta Liberation Army was the cause of it all.

"I had to use my status as a fucking hero in the making and call on the help of that fucking weirdo Mei and that other nerd Saiko to even bust out of jail! And I'm not even sure if the fucking coppers are still looking for me! That was the worst fucking day of my life, ever, and now this fucking Deku is supposedly some sort of bigshot in the heroic fashion and accessories industries? No fucking way, I call BS on that! The fucking nerd had to be either cheating his way through like the loser that he is, or even worse...."

Bakugo didn't get to finish as Aizawa knocked him out using acupuncture, but the damage was already done. The whole world now knew the extent as to which the Meta Liberation Army and the MLA's ideology of Quirk supremacy controlled Japan, and it was all thanks to one dumb blonde being unable to keep his damn mouth shut and his bigotry to himself.

Among the now appalled, ashamed, and deeply embarrassed audience, All Might, the number-one hero and mentor to many U.A. students, watched the scene unfold with great interest. He'd always been intrigued by Izuku's intelligence and determination. One question continuously nagged at him; how could someone so young and passionate about heroism not possess a quirk?

Unable to shake off his suspicions, All Might's attention shifted toward Eri. The young girl's white hair and other subtle physical resemblances to Hiashi Midoriya and the connection between Izuku and the villain All for One did not go unnoticed. [4]

All Might's intuition told him that there was something deeper about Izuku and his family, but he decided not to confront him, at least not yet. Instead, he would keep a close eye, carefully observing the young inventor and his mysterious little sister.

Back at the presentation, Izuku, unaware of All Might's silent scrutiny, carried on showcasing his latest gear designs to U.A, helping to salvage a small bit of the ceremony after Bakugo's sudden outburst ruined it all. He hoped that by contributing to the Hero Community, he might one day unravel the mysteries surrounding his own family, and find his rightful place in this world.

As Izuku walked home with Eri, the weight of the day's events seemed heavy on their shoulders. All the eyes that had been on them, the suspicions that swirled around them, and the secret that Eri carried; it was all too much to bear alone.

But as they walked hand in hand, their bond unbreakable, they knew that they would face the challenges of tomorrow, together.

The path of the Midoriya family had turned into one of secrets, suspicion, and a love that was both uncertain and unbreakable. Izuku swore to carve a better future for his family, while Eri held her own secret she kept hidden from the world – her deep, strong feelings for her older brother. They would rely on each other's strength as they navigated their way through the complex webs that connected their past to their future.

The days that followed were filled with discreet training as Izuku sought to master his newfound quirk, "Power of the King." This mysterious power was a combination of his Dad's feared All for One Quirk and his mother's telekinesis, with all of their powers and abilities, but had one extra feature - the ability to extract the hearts of others and use those hearts in the form of weapons called Voids. [5]

Fearing for his life and the safety of his beloved little sister Eri, Izuku registered this powerful Quirk as 'telekinesis' and kept his true powers hidden, only using them to help clean up the trash-filled Dagoba Beach and deal with corrupt heroes and criminal gangs under the cover of night.

In the shadows, his father, Hiashi, continued to make plans to counter the ever-growing threat of the Meta Liberation Army and their minions lurking within the Hero Commission.

Meanwhile, Eri found her own courage, overcoming her fear and anxiety to learn from her father how to harness her potent time manipulation quirk.

Izuku was accepted in UA as a member of a support course and soon became a key member, stunning his classmates and teachers with his innovative ideas and ground-breaking inventions.

His charisma and kind nature soon made him the focus on an unintentional harem which consisted of his [unbeknonist to him] other younger half-sisters, the bubbly brunette Ochakou Uraraka and the reserved musician in training Kyoka Jiro, idol in the making Nejire Hado, eccentric and strange but also fun loving and jovial inventor Mei Hatsume, the devout Christian Ibara, and rich heiress Momo Yaoyorozu.

Izuku of course had no idea of the fact that these girls even liked him, much less had deep feelings for him, being occupied with crafting and improving his inventions, taking care of Eri and working out his feelings for her, and secretly training with his true Quirk.

While the girls pined for Izuku's attention and Bakugo was busy brooding over the fact that the nerd was getting more attention than he ever would get like the little insecure, arrogant, childish bitch he was, All Might shared his speculations about Eri and Izuku with Principal Nezu. The principal, however, dismissed his worries with a laugh, advising him to focus on dealing with the remnants of the Yakuza scattered across Japan instead.

As the Midoriya family faced new battles and challenges, Izuku's unintentional harem at U.A. joined forces to uncover the truth behind their shared crush. Utilizing Mei's technological skills, Momo and Nejire's wealth, and Ochako's connections in the construction industry, the girls tracked down the location of the Midoriya mansion.

Upon arriving, they were greeted by a surprised but delighted Eri, who had been worrying about her beloved brother's loneliness at school. After getting over the initial shock of discovering Izuku's younger sister and his affluent background, the girls couldn't hold back their feelings any longer.

Their love for Izuku finally laid out in the open, they anxiously awaited his response. To their overwhelming joy and relief, Izuku accepted their love, embracing the complex relationships that had formed.

The girls allowed Eri to join the harem under one condition: no one could know about their relationship with Izuku until they all left U.A.

Simultaneously, danger continued to brew as Re-Destro, the shadowy leader of the Meta Liberation Army, collaborated with Neo-Confederate Democrat [6] terrorists from the USA to create a sinister mech weapon known as the "Endlave." With this powerful technology, the MLA intended to seize control of Japan using pro-heroes and the Hero Commission as their unwitting pawns.

As the secrets within the Midoriya family unraveled and the shadows of impending conflict loomed ever closer, Izuku and his loved ones stepped into the unknown with the same unbreakable bond that had carried them this far. United, they faced the uncertain future with determination and courage, willing to do whatever it took to protect their happiness and the world around them.

The schemes of Re-Destro and the Meta Liberation Army (MLA) began to take shape as they attempted to wield power over Japan. Unbeknownst to them, their age-old nemesis All for One, also known as Hiashi Midoriya, was secretly alive, having made plans to deal with the growing threat.

Before Hiashi could act, a group of vigilantes, led by Knuckle-Duster, rose in rebellion against the corrupt Hero Commission and the Quirk supremacy of the MLA. This group, calling themselves Funeral Parlor, sparked a conflict that escalated into a full-scale civil war, drawing Japanese nationalists and imperialists to their cause. Even moderate Pro-Heroes joined forces with Funeral Parlor.

As the civil war raged on, Izuku's "Power of the King" led him to join the ranks of Funeral Parlor. With his unique quirk, he guided the rebels to victory after victory against the formidable MLA, despite Re-Destro and the corrupt Hero Commission having been able to mass produce and utilize Endlaves against the resistance forces fighting against the corrupt system.

In time, Funeral Parlor emerged victorious, restoring the imperial system that existed before World War II. [7] The leaders of the MLA, including Re-Destro, were tried and executed for their nefarious schemes. Quirk supremacy and the Hero Commission were dissolved, heralding a new era in Japan.

With newfound stability, the Japanese government reestablished control over Korea, Sahlakin, the Kurils, and Taiwan, incorporating them as prefectures. They also provided support to a revolution in China, ushering in the return of historical Japanese protectorates such as the Empire of Manchukuo in Manchuria, the Mengjiang United Autonomous Government in Inner Mongolia, and the Reorganized Government of China. The restored Ming dynasty took power in a new, democratic Chinese government, reshaping the political landscape of the region.

As the dust settled on the sweeping changes brought about by the civil war, the Midoriya family and their allies forged ahead, determined to make the most of the new world they had fought so hard to create. Though challenges and uncertainties remained, their unwavering resolve and strength in unity would continue to guide them into the future. And, in the heart of it all, Izuku Midoriya, armed with his "Power of the King" and the love of his family and friends, continued to be the shining beacon of hope in a rapidly evolving world.

The Midoriya mansion hummed with laughter and animated conversation as Izuku and his harem spent time together. Among them were Himiko Toga, the pseudo-vampiric girl, and Itsuka Kendo, a martial arts heiress turned heroine-in-training. Both girls had joined Izuku's harem during the civil war and were now just as fiercely devoted to him as the other girls in his life.

Unbeknownst to Izuku, his harem, and the rest of his family, they were being observed through the window by the mysterious Koichi Haimawari, also known as the vigilante Crawler. As Koichi watched the scene, he noticed the loving look on Eri's face when she glanced at her older brother and accurately deduced that the young girl had feelings for Izuku. The unmistakable chemistry between Izuku and the other girls evoked a chuckle from the vigilante.

Koichi mused to himself, "Wouldn't be surprised if these two and the other girls have a lot of children very soon." With that, he vanished into the morning mist to patrol the city, leaving the loving family to their moment of peace.

As Koichi disappeared into the shadows, Hiashi caught a glimpse of the vigilante from the window, heading back to his newspaper with the remark, "Kids these days." Hiashi had long since left behind his life of crime, embracing a new life as a family man, loving father, and, one day, a hopeful grandfather.

As the morning carried on in the lives of the Midoriya family and their loved ones, it marked the beginning of a future filled with love, loyalty, and the unwavering hope that had carried them this far.

And there, amid the voices of laughter and the warmth of affection, Izuku Midoriya stood at the heart of it all - the beacon of hope that would guide them through whatever challenges lay ahead on their new path.

[1] Eight Precepts of Death. For a dwindling Yakuza organization turned revolutionary group and villain organization, the Shie Hassaikai sure is fucking stupid. Eliminate all Quirks to bring peace and rule Japan in the aftermath - what a stupid and delusional plan, Even the Zero Requirem, senseless, pointless and stupid as it was, was better thought out than this, and I'm no fan of Lelouch Lamperouge or how idealistic or blind he was in the canon of Code Geass.

[2] Considering how the MLA's name is the fucking Meta Liberation Army and liberation is a concept associated with communist revolutions, it's safe to say that the chaos and turmoil of the start of the Age of Quirks caused Japan to go red and sadly abolish the monarchy. Unfortunately, what little remained of the aristocracy, nobility and royalty got replaced with something much, much worse: Eugenics and a class system based on powerful quirks.

[3] Since Hiashi got his face and body fixed and managed to return to his family without being discovered by the so-called heroes or other villians, he doesn't really need to be on the ground to manage the League much anyways. Tomura will destroy himself fighting endless hordes of Pro Heroes while his 'mentor' will be spending proper time with his wife, son and one of his youngest daughters, weakening the MLA and keeping the Hero Commisson distracted.

[4] All Might might be the number 1 Hero and an idealist who sees the good in everyone, but he's not stupid. He would have been tracking All for One for a long time ever since Hiashi killed his mentor Nana Shimura, and would have a rough idea of Hiashi's many lovers, wives and one-night stands.

[5] Guess which now-obscure 2011 anime and visual novel series I took this idea for Izuku's true Quirk from?

[6] The emergence of Quirks would probally give rise to a lot of new terror groups and resurrect some from the first half of the 20th century. Considering how some people that call themselves 'progressives' in America deny the crimes of Woodrow Wilson and either try to lessen or wave away the holocaust of German Americans that occurred under his brutal regime due to 'making the world safe for democracy' in a manner that makes Neo-Nazis blush, or because Wilson was on the left and the orange Stalin of an ex-US president these morons are crusading against is a conservative, the open resurgence of Confederate Democrats and their genocidal ideology in the world of MHA is not unlikely.

[7] The Righteous Army and the Kodoha faction from Imperial Japan are celebrating and having a good time in heaven at this.

[8] Unlike some other harem anime and manga protagonists, Izuku and the girls of his harem are not stupid and know that sooner or later, there are going to be lots of little feet walking around the mansion where he and the harem are going to live. Also, the Vigilantes sub-series needs more love.

[9] Eri is around 12 when the story starts, and Izuku is 15. By the time the civil war ends she's around 16 and Izuku, Ochako, Kyoka, Toga and Itsuka are at least 17-18 and Momo is around 19-20, so that age difference should really matter much.
