Hello and welcome to another experimental fanfic of My Hero Academia, in which a new inspiration popped into my head in an unexpected way, and I'm sure you'll be baffled as to what made me come up with an experimental and risky fanfiction I wrote, so below is the explanation on why.

This started last year when I was surfing on Twitter where a Twitter article announced that Mato Seihei no Slave (aka Chained Soldier) would be getting an anime adaptation within 1st QTR 2024, and out of curiosity I checked it on Google and discovered that it was based on an ongoing manga and out of curiosity I checked it out, and after reading the first four chapters (via online) my curiosity got piqued and continue reading the online manga.

Just two weeks ago the anime premiere and so far the first episode retained everything from the source material while the manga is currently on chapter 124, and as I was awaiting the third episode of the anime I sort of made at least three Mato Seihei no Slave fanfictions here, but a wild idea popped into my head, in which I thought of giving it a try.

Yup, I came up with the idea of using the My Hero Academia characters as the ones set in the Chained Soldier plot, and there Midoriya came to mind as I thought of having him becoming the SLAVE whilst the female characters would be the MASTERS.

While Midoriya would be the male lead, I had to figure out who would be the female lead, which I managed to narrow it to Kendo, given that her personality and grit are similar to Kyouka Uzen's.

As for who would portray the other female characters and their units, I'll figure out a way, but for the meantime I'll concentrate on the initial plot and see if this fic would be well-received before deciding to make future chapters…

And lastly, since this fic features mostly elements from Chained Soldier, this will be AU, hence there won't be Quirks or any Hero Course schools like UA Academy or Shiketsu High, hence in effect there won't be any male pro heroes here.

One more thing…for those who are familiar with the manga I'm sure you know that Chained Soldier features REWARDS…which would be shown here in an UNCENSORED way, hence this fic would be M-rated.

Well then, read on and enjoy!


Ch. 1: Unmeinodeai

Japan.

The country that is located within South East Asia, quite near different Asian countries such as China, Taiwan and the Philippines, is seen and that country is ruled by the Diet, and are handled by the Emperor and the Prime Minister. After their defeat at World War II, the country began to change for the better, and for several decades Japan vastly improved, mostly in the technological department yet their culture and values remained the same, as most Japanese citizens remained hospitable to visitors, residents and tourists alike.

The scene then zoomed further and you can see that the scene shows that the place being shown is Tokyo, which is bustling with people who are walking the busy streets, some riding vehicles, and others riding on bicycles. There are several types of people seen on the streets; adults, children, and even infants being carried by their parents. Businessmen, businesswomen, students, policemen, all kinds of persons are seen, and they were doing their usual activities as if they do not mind it.

Shops are open and the merchants are selling their merchandise and are enticing people to buy them in hopes of earning money. It was a typical day and it seems that people today are lively and felt that their lives are full of blessings and couldn't ask for anything more, as some are happy with stable jobs, students studying in the best schools, and more, and some even chatted with one another feeling that today is a good day.

"Hey!"

"Nice day, isn't it?"

"Today is a good day..."

"I love my job..."

"Life is so good..."

"I wish I have a good day..."

"Lots of money..."

"Lots of girls..."

The scene later shifts to a certain area, where business is thriving the area is frequently being besieged by customers which are a mix of adults and teenagers, and they appeared to be avid collectors, as they are looking and buying second-hand items which are technological in nature, and their reasons for patronizing the said shops are purely economical in nature - cheaper prices and practicality. You can see several shops selling HOT items for cheaper prices, such as smartphones, android tablets and even laptops, and despite being second-hand items, they appeared to be in good working conditions, and some of the customers are willing to buy them as long as their desired items are working fine as well as to save money for budgetary reasons, and the merchants are using subtle means in enticing passing customers.

"Hello...please by our items..."

"They are cheaper..."

"...they are in good working condition..."

"You can try them if you like..."

"I promise you will like them..."

"I promise you will get your money's worth..."

"Here are the items on our display..."

"Pick the one you like..."

The area in question turns out to be Akihabara, and the area is thriving and many merchants set up shops to attract passing customers and entice them to buy their products by showing the items and offered cheaper prices while assuring them that the items are in good working condition, and their marketing strategy worked as some passing customers were intrigued after hearing that so e gadgets are being sold in cheaper prices, and they began asking the merchants what itens do they sell, and the merchants showed to the customers the items they are selling, ranging from smartphones to android tablets and even laptops.

Then the scene shifts to another nearby shop, where a merchant is also selling second-hand items, but unlike the other shops, this merchant is selling something else and is catering avid collectors, and the scene shifts inside the shop where you can see the items being sold, which turn out to be classic console units and games, all being displayed on the shelves, and one by one you can see the following consoles being on display, which are:

- Nintendo Famicom

- Super Famicom

- Sega Mega Drive

- Game Boy Color

- Game Boy Advance

- Neo Geo

- Sony Playstation

- Sega Saturn

- Nintendo 64

In a matter of minutes customers passed by the shop, and most of them are avid collectors and fans of video games, and they were immediately intrigued by the items on display and they looked at the items, as some appeared to be unaware that such classical consoles actually existed, and they began asking the merchants if those consoles and its games are really something to be owned, which the merchant nodded and assured to them that the classic games are RARE, and are fun to play with, saying that even with popular games today that are released on current consoles such as the Sony Playstation 4, the Microsoft X-Box One and the Nintendo Wii, the consoles on display are even COOLER due to its nostalgia factor.

"Are they really cool compared to today's consoles?"

"Yes...they ate cool..."

"Seriously?"

"Yes, sir...they are the very first games...and they are the popular ones in its heydays...and they are RARE to find..."

"Hmm..."

"Would you like to try them...?"

"..."

"I promise you will not regret it..."

Shizuoka.

Shizuoka Prefecture is a prefecture of Japan located in the Chūbu region of Honshu. As of September 2023, Shizuoka Prefecture has a population of 3,555,818 and has a geographic area of 7,777.42 km2 (3,002.88 sq mi). Shizuoka Prefecture borders Kanagawa Prefecture to the east, Yamanashi Prefecture to the northeast, Nagano Prefecture to the north, and Aichi Prefecture to the west.

Shizuoka is the capital and Hamamatsu is the largest city in Shizuoka Prefecture, with other major cities including Fuji, Numazu, and Iwata. Shizuoka Prefecture is located on Japan's Pacific Ocean coast and features Suruga Bay formed by the Izu Peninsula, and Lake Hamana which is considered to be one of Japan's largest lakes. Mount Fuji, the tallest volcano in Japan and cultural icon of the country, is partially located in Shizuoka Prefecture on the border with Yamanashi Prefecture. Shizuoka Prefecture has a significant motoring heritage as the founding location of Honda, Suzuki, and Yamaha, and is home to the Fuji International Speedway.

The scene shifts at Musutafu, which is a city where it is located somewhere in Shizuoka Prefecture. The city appeared to be peaceful as it looked like everyday life is the norm, as people are doing their daily lives, such as attending school, reporting for work at offices and establishment and the such, but this isn't what it appeared to be.

Decades ago, portals to another dimension mysteriously began to appear all over Japan. The dimension was about as large as the Tokyo Metropolitan area and was named Mato. The world of Mato contains the very dangerous and demonic-looking entities called the Nomu, as well as the mystical Peaches that grant special abilities to those who eat them, but only to women. For some reason men were unable to gain said abilities even if they consume a peach.

With this being the case, women became the dominant gender. In order to keep the Mato portals under surveillance, the government created the Anti-Nomu Corps, an organization composed entirely of women who have gained abilities from the Peaches.

One day, the scene shifts at an office where a group of world leaders, all women, attend a conference. With the appearance of another dimension, dubbed Mato, gender equality is no more, thus this caused some of the women to develop a superiority complex, and started to treat their male colleagues with disdain and look down on them.

"You! Fetch me my cup of coffee!"

"I want a cup of tea!"

"Clean my table!"

"Where's my quarterly report?"

"You asshole! You spilled milk on my Victoria Secret dress! Now you'll pay for it!"

"You men are terrible! Even a simple housework you couldn't do it right?"

"You men are the lowliest!"

"Begone! Get out of my sight!"

-x-

Later during the day, the scene shifts at Aldera Middle School, where the next scene shows that Izuku Midoriya, a third year student, rushes to clean up the classroom before the bell rings while his classmates, goof off.

"Good luck, Midoriya!"

"Have fun!"

"Hey…! At least help me here!"

"Sorry…I have things to do…"

"Me too…"

"H-hey…no fair…!"

"See you later."

"Tah-tah."

"…"

The boys look outside, seeing all the female students arrive tardy, as usual. As some of the girls show off their supernatural abilities, Izuku remarks that men cannot receive Peach blessings and thus their lives are inherently more difficult. Izuku sees a boy holding hands with a girl and one of his classmates explains they got together after the boy won a sports competition, much to Izuku's frustration.

Izuku is advised that his cleaning skills will be desirable later in his life, but deep inside he wishes to be popular now, though his classmate said that no matter what, life today is wishful thinking.

"Better accept it, Midoriya."

"Yeah. We guys are just second-rate."

"Well…"

"Blame it on the Mato incident."

"Yeah, Midoriya. That's the reason why we boys are looked down at."

"Geez."

"That's life, Midoriya."

"He's right. Better get use to it."

That evening, Izuku and a male classmate of his ride home in an overly-crowded male-exclusive train (whereas the female-exclusive train is open and spacious), after which the classmate complains about his upcoming working adult life once he graduates high school and university.

Izuku just sighed as he had to put up with his classmate's ranting, but then some of the other male passengers echoed similar complaints as they are already feeling that the women are getting special treatment whilst the male population are being treated like SPARE PARTS.

"Damn it…"

"I can't believe that we'd be suffering like this…!"

"This is the fault of the Mato!"

"Yeah. Since my ex-girlfriend at a peach she started to treat me like a servant till she broke up with me!"

"Heck, even my wife filed for divorce the moment she also ate a peach!"

"This sucks!"

"I wish I could gain an ability!"

"Me too!"

When one of his classmate's buttons comes undone, Izuku quickly sews it back on, which his classmate thanks him though Izuku said that it's okay. There Izuku explains that he became proficient at housework thanks to his mom who would punish him if he did not do it. Izuku's classmate then refers to something that happened to Izuku's mother during a Mato disaster.

It is then revealed that ever since Izuku's mom, Inko, disappeared Izuku has been living alone and had to struggle in living by himself and yet he is holding onto hope that his mom is still alive.

His classmate realized what he said and apologized though Izuku assured to him that he is just fine, which the classmate was mentally relieved.

"It's fine."

"Really, Midoriya?"

"Yeah."

"You sure…? I didn't mean to…"

"Don't worry about it."

"Promise?"

"Yeah."

"Okay."

-x-

Much later, as Izuku walks home alone, he wonders what he would do once he gets into the stage where he would start in his working adult life, not wishing to merely get a day job and then then wait for death like everyone else. He mentally wishes to go somewhere where he can be of importance. Suddenly, the air around him becomes very misty and he finds himself transported the world of Mato.

"Huh…? Is this…? No, it can't be…?"

Midoriya looked around and observed his surroundings and he is able to confirm that he is really in the Mato World and he realized what this means, and he momentarily panicked before managing to compose himself and not give in to panic, taking a few deep breaths until he is able to calm himself down.

"Okay…calm down…take it easy…relax…everything is going to be fine…"

Nervously, Izuku pulls up a manual on his phone to figure out what to do in a Mato disaster. The manual states that, though most portals or gates are fixed to one place, sometimes they appear randomly. Cases in which ordinary citizens are caught up in the random portals are known as Mato disasters. Izuku realizes that this is the same thing that happened to his mother.

"No way…am I going to end up in the same way as my mom…?"

The manual instructs that in the case of a Mato disaster, one should stay put and wait for the Anti-Nomu Corps to arrive, which means that he would have to wait for help to arrive, thus he shouldn't be loitering around this place, hence Izuku has no choice but to stay here for now until help arrives, which he intends to do so.

"I hope help arrives soon…"

Izuku sighed and decided to wait it out, but is suddenly something appeared and as Izuku glanced at it, he stared wide-eyed in horror as something else appeared before him and the teen boy instinctively jumped out of the way as that something smashed the area that Izuku previously stood with its bare hand.

It was then that the teen boy realized something: he is being attacked by a large Nomu, and now he is being targeted and he started to ran for his life as he flee from the Nomu while thinking that, although he wanted some excitement in his life, he did not want this.

"WWWWWWWAAAAAHHHH!"

"RRRRROOOOOAAARRRR!"

"I SAID THAT I WANTED AN ADVENTUROUS SITUATION BUT NOT LIKE THIS!"

"RRRRROOOOOAAARRRR!"

"WHAT DID I DO TO DESERVE THIS?!"

"RRRRROOOOOAAARRRR!"

"SOMEONE HELP!"

"RRRRROOOOOAAARRRR!"

As he continue to ran away from the pursuing Nomu, another Nomu appeared and is heading straight for him, but he blinked his eyes as he sees that a woman is on top of the Nomu. The woman, gripping the Nomu, is riding with a chain around its neck, orders Izuku to stay behind her while she handles the other Nomu.

"Listen carefully!"

"?"

"You want to live?"

"Y-yeah…?"

"Then stay behind me!"

"Eh…?"

"Do it now!"

"O-okay…!"

The woman quickly disposes of the Nomu, slicing them up with her sword. However, the Nomu she is riding is killed in the battle. The woman explains to Izuku that she is Itsuka Kendo, Chief of the 7th Unit of the Anti-Nomu Corps and assures to him he is in safe hands, which Izuku appeared to be relieved upon hearing this and is anxious to go home.

Suddenly, another swarm of Nomu descends upon them. Kendo conjures another chain around an injured Nomu and she orders Izuku to ride on top of it. There Kendo and Izuku ride the Nomu as she carves up all Nomu in their path. As another Nomu attacks, Kendo orders her Nomu to dodge, but it is slow to react. With Izuku clinging onto her, Kendo leaps out of the way as her Nomu is destroyed. Using a talisman, Kendo creates a barrier that wards off the other Nomu. However, Izuku soon finds that the Nomu are breaking through the barrier.

To Be Continued...


Hope you liked this chapter, as it mirrors the first half of the Chain Soldier's chapter 1 of the manga…though the difference is that it is set in the My Hero Academia world and the such, but more are on the way as the first battle ended in a cliffhanger…

See next chapter on whether Midoriya would survive as Kendo faces another wave of Nomu…

See you next month…
