Prologue
It was a cool winter day in japan when the fire nation attacked. No. Wait. Wrong amazing show. In this one we find our main character riding a train on his way to what would be the day his future at a hero would be decided. The UA university entrance exams. The most prestigious hero University in all japan, heck maybe even the whole world.
Here on this train we find Izuku Aizawa browsing through his phone, trying to calm his nerves. Unfortunately there wasn't any recent hero news that he didn't already know about, so he was reading a list of top 10 villain schemes that changed the world in an ironic way. From a villain trying to melt the polar ice caps to flood the world, but fixing the hole in the ozone instead. To a villain trying to take over the United States, but instead getting a new and better judicial system in place.
Though his favorite one was number 3, a woman who is taught in high school in both Quirk ethics and History. The villain was named Plague. She was an American, and one of the first people in the world to develop a quirk. Her quirk allowed her to develop any disease she could desire, as long as she knew how it worked. Though because of quirk discrimination when they first started appearing, she hid the fact she had one quite well. So no one batted an eye when she started to study to become a microbiologist.
She was a very patient and intelligent women, she studied for years to make sure she could create the perfect disease so it would never be cured. Her goal? The eradication of man from Humanity. She believed men to be nothing but a plague themselves, and thus should be eradicated. She was damn clever on her application as well. Due to her intelligence, she gained prestige across the whole world in her field. She found cures to many diseases, including cancer and AID's.
No one knew that while she was traveling she was purposefully spreading 2 plagues. The first one was a cover, to make sure that if she was caught, no one would suspect that she also created and spread her main virus. This one was simple, and easily cured by other microbiologists, though it was in fact deadly, she was more focused on it be contagious.
The other one though, was a virus that latched on with the first and only effected men. The
Problem was, she was very patient. She knew for her goal to succeed, she wouldn't be able to live long enough to see it happen. She knew that if she made her quirk work to fast, it would be quickly discovered. While she made the quirk highly resistant to curing, it was impossible to make one incurable. It was also impossible to make it that no man could be resistant to it. Though as time would go on, it would do exactly as she wanted it to do. Which was once it infects a man, it made it difficult to produce sperm with the Y chromosome and eventually make it impossible, thus only able to produce daughters.
Eventually the early hero's discovered that the first plague would always start spreading in any country after she appeared. Since she didn't want her quirk to be discovered, she went in peacefully. What she didn't know was that doctors had discovered a way to tell if someone had a quirk or not, so she was forced to reveal what it did. Without a way to suppress quirks at the time, she was deemed too dangerous to let live, and was sentenced to an immediate death.
She didn't care though. She finished with her task.
After giving them the information on how to cure the obvious plague, so as she planned, they didn't suspect a second one. Everyone found it creepy how she smiled in the electric chair.
So as everyone's lives continued on as normal, it was quickly discovered how the male birth rate was declining. People first suspected it to be another oddity associated with the appearance of quirks, so nothing was done about it. That is until after 150 years since the day quirks appeared, male birthrate didn't go up. In fact now only 15% of humanity was male, with each generation having less and less.
Many believed it to be a good thing, and was just the next step of humanity. That is until geneticists revealed that if man was wipe out, the only option for humanity moving forward was cloning, and over time DNA would get so muddled that humanity would never survive long term. So to preserve humanity moving forward, most scientists and doctors started looking for the reason behind the decline.
After 5 years a doctor in Britain discovered the disease, and immediately spread the word. Every single specialist started working on a cure, after all they were down to 12%. Early on they were able to cure men who already had some resistance to the disease, but it took 15 years to find a more widespread cure. Due to the fact that there were many organizations attempting to stop the cure from being discovered, some even resorting to acts of terrorism. It was truly a dark time in human history.
Nowadays there are still men who cannot be cured for one reason or another. Thankfully enough of men were cured that they no longer faced extinction, so the race for the car has slowed down considerably. 30% of babies born nowadays are male.
Now you might be thinking the irony of the story is that she cured many widespread and deadly diseases, or that her plan would have wiped out all humanity, not just men.
Nope.
The irony in the story is that due to the dangers humanity faced, the whole world implemented several plans. One being that polyamory was no longer illegal in any country, and was no longer frowned upon as much. Another that they implemented a new profession until humanity until a full cure is found. It's called birthers. It's a job that can be done by both women, and cured men. While every family is given money from the government as incentive to give birth, birthers are those that either give birth to multiple children, or impregnate women multiple times. While a majority of birthers are men and women who love children, there are those who abuse the system to not work.
Why is this ironic? Well it's because according to Plague she was 'cheated on' and "men are nothing but a filthy, disgusting disease." But after the media found the man who 'cheated' he informed them all he did was ask about making their relationship polyamorous. He told her, that while he still loved her deeply, he also developed feelings for a man name Alex, and asked her if he could join the relationship with them. She apparently lost it and started calling him a pig and a cheater, despite him never doing anything with Alex.
While she became a villain because of her boyfriend wanting a polyamorous relationship. She made polyamory widespread and common place.
Izuku laughed as he continued to read the list. He wondered why he liked that one more than the others. 'Maybe because people would have seen my quirk as worse than they already do?' He thought.
Unfortunately, Izuku had a quirk that many considered villainous, even by his parents, and was put through a living hell for a vast majority of his life.
His quirk was called Incubus. It was extremely powerful. He was able to produce pure energy to enhance his physical capabilities or energy attacks. He was even able to manipulate space, including gravity, to a certain degree. So far he hasn't found a limit to how much power he could put behind his attacks, but they require a certain resource.
Female pheromones.
That's right, he has to gather female pheromones through skin contact to power his attacks. The more intimate the acts, the more pheromones he collects, and pheromones from multiple women makes his attacks even stronger. Though the women have to desire him, and he has to desire them in return.
What's that? Doesn't sound to bad you say? Well on it own it doesn't. But there is one power he has that doesn't require any resource. He calls it gaze of lust. Through eye contact he can activate it to force a woman to lust after him and desire him enough that they won't be able to resist him. He absolutely hates it, and absolutely refuses to it. That power is what caused his whole life to shatter and go through what he did.
Izuku was in deep thought, remembering all the pain he went through, when a light snore brought him out of his thought. He looked down at his lap with a light smile. No he wasn't smiling at his junk, he was smiling at the women using his lap as a pillow.
Mei Hatsume, inventor extraordinaire and Izuku's girlfriend of half a year. He can say without a doubt that he loves this girl with all of his heart. They met just over a year ago and that one event change the course of his whole life.
Izuku starts gently petting Hatsume, trying to avoid waking her. He notices a smile appear on her face as he does so. 'It still amazes me how different my life is now.' Thought Izuku. 'For her sake, I'm just glad I made it in time.'
As Izuku slowly started to drift off into sleep himself, not noticing a girl with brown hair in a bob cut looking up from her book smiling at the two of them. 'They are so adorable!'
