My avatar is the heroine

She quickly took half a step back, but in an instant a flash of light appeared, and her vision blurred, and the pain on her face seemed to disappear.

"Wait, what just happened?"

Black Eyes shook his head, offering no response.

If I transform quickly enough, you won't see the nightingale appear.

Yes, she just summoned the Nightingale in an instant, cast a healing spell on the other party, and then disappeared.

The timing was perfect, exactly the instant Saten Ruiko blinked. For a powerful assassin, capturing the blink of an eye isn't too difficult.

At that time, almost no one noticed this place.

"Perhaps this is just a hallucination."

There are some people watching this place, but the changes are instantaneous and Kurohime has a natural talent for avoiding trouble, so it shouldn't lead to any bad consequences.

"Hallucination?"

She was very clever and immediately realized that Kuroko also had similar healing abilities.

Although it was a blow, compared to LV5, the healing class didn't seem to have anything special.

That evening, after the incident ended.

Back in her dorm room, looking at the huge, empty room, Kurohime felt extremely uncomfortable living alone.

Although it's nice to live in a big house, this room is bigger than the entire first floor of the villa, with two beds placed sparsely, one of which is empty.

"Let's rest. Oh, and let the clone go to the other side."

If you think it's too big, then just add more people.

Now that I have so many clones, and there won't be any troublesome battles in the near future, it's not bad to select two everyday types to reserve a spot and practice their usage time.

After summoning Yukino and Makise Kurisu, Kurohime went to the bathroom next to the room and looked out at the distant sky through the window.

This is the Tokiwadai dormitory. Across the small garden is another building. The teachers in the distance don't have the tense atmosphere of evening self-study sessions that I used to have in high school.

"In the end, the learning life of superpowered individuals is not too difficult."

Those who can come here are all Level 3 ability users. In Academy City, which places great importance on the development of superpowers, their importance is self-evident.

"230 million people."

Compared to his hometown, a city with tens of millions of people in his previous life, Academy City really has a very small population.

However, the exaggerated per capita area and automated infrastructure have indeed made the living conditions here much better.

After all, airships patrol the skies above the city every day to broadcast important news, and there are also automated robots on the streets.

"By the way, let's take this time to study the time machine."

Makise Kurisu had a flash of inspiration and decided to focus her work on areas she was good at.

In Steins;Gate, Rintaro Okabe's initial time machine was created in a telephone oven due to a series of coincidences. Initially, he could travel back in time by sending text messages, thus altering a predetermined history. However, this was actually the culprit behind the shifting world lines, causing Rintaro to jump to a terrifying world line where Mayuri's death was inevitable.

In an attempt to change Mayuri's fate, Rintaro Okabe begins a terrifying and endless series of world line jumps, but no matter how hard he tries, Mayuri is destined to die the moment her pocket watch breaks.

Even more terrifying is that not all of Rintaro's world lines are safe. For example, in some world lines, his friends are assassins, and in others, a world war will break out in the future.

Logically speaking, the world of A Certain Scientific Railgun shouldn't have such a terrifying situation where changing the past alters the world line, leading to a convergence of world lines from which there's no escape.

Even if things have changed, it shouldn't be that bad.

"But how should I put it, if a powerful organization finds out about this, it will definitely be a problem."

Even if it's not a time machine, and even if it's being monitored, no one else would understand. Besides, once the experiment begins, the system will distort information about Aleister and others, so there's no need to worry about the consequences.

"The problem is, I have no clue what to do. Should I start making a telephone oven?"

Makise Kurisu began researching theoretical information about this world.

Of course, the secrets that can be made public on the official website are not very dangerous.

But that's enough for her.

Furthermore, while Rikka Takanashi's creativity couldn't immediately produce a time machine, she could still concoct some that were somewhat similar in principle. Through research, a large number of formulas and related content appeared on paper.

"Telephone oven, is the principle really that simple?"

The equipment requirements are too high, but as long as you have Rikka, the experimental equipment is not a problem at all.

After some time, a simple oven appeared in the center of the room.

"Set the time, 1 minute, message content... This is the message my future self will send."

She checked and found that there were indeed no records on the phone that came with the system.

After making the decision, he turned on the oven. As a series of electric currents appeared inside, Su Lin and all his clones felt a sharp pain in their brains for a moment, and then found that nothing had changed.

"Success?"

I quickly took out my phone and found that there really was a new text message: This is a message sent by my future self.

Received one minute ago.

[Due to changes in world lines, the system has implemented memory protection; you can retain memories from other world lines.]

The signals in my brain also indicated that I had succeeded.

The shift in the world line inevitably means that this message altered the past, and thus changed the course of history.

In other words, in this minute, because of this message, Hei Tong... or rather, Su Lin should have done something.

"Damn it, does the system even know what I did in the last minute?"

[To protect the timekeeping device's data, the system modified the intelligence received by the monitor. This change was caused by erroneous intelligence.]

"Ok."

It was a little scary, but Su Lin was somewhat tempted.

No matter how dangerous it is, once a person has the ability to change the past, can he resist doing it?

So, what about going back to the past?

Today the editor said that the book involving My Hero Academia (mine) is basically doomed. However, I asked if it's possible to delete the earlier parts and make some minor edits later.

Then Nanxi said she could make some changes first, as she didn't have time to process individual books at the moment.

I'm not sure if I can save it, but I'll give it my best. I've replaced everything mentioned in the content starting from chapter 104.

If you remember anything, please leave a message in the comments section and I will delete or replace it.

Several plot points related to Xiaotai have been replaced with ellipses. Please note that you should not subscribe. That's all.

Is there any chance of saving this book? At present, there is, since this book has nothing to do with My Hero Academia afterward.

Chapters 1-103 are definitely gone; needless to say, they will be deleted later.

I've revised the chapter starting from 104. We're racing against time now, but with so little time, there are bound to be details I've overlooked. So I hope everyone can help out.

If you don't mind, in this thread, start counting from 104. Go back and read the chapter that is called (remember to refresh the chapter content before reading, as it has been revised). After reading, find the chapter related to My Hero Academia (whether it mentions names or plot points) and mention it at the end of this chapter, then I will go and revise it.

Thank you everyone.

Those with extra time can submit more chapters.

……

This is the last paragraph; the unmodified content is mentioned here.

I just checked the group chat, and it seems some books might be taken down first and then revised (probably). Don't panic if you see a book being taken down; there should be a way. I've already spoken to the editor about the situation, and we'll wait and see how it's handled.

Chapter 199 Meeting at the Academy

"It seems there's no need for me to deliberately change the world line."

They've all transcended conventional worldviews, so following the plot offers a greater sense of control than altering it.

In a world like Railgun, there are many high-level beings. If you go too far, you might really kill yourself.

"Oh well, I'll go for a walk outside Tokiwadai before curfew starts."

The scenery in Academy City is really beautiful. There are large parks and wilderness areas in the city. Entering those places gives you the feeling of going from the city to the countryside.

The economy here is self-contained, and every year countless people are desperate to get in.

Leaving Tokiwadai, on her way to her former apartment, Yukino (whose time with Kurome) suddenly saw a familiar figure.

The other person, carrying a bag, hurriedly ran across the middle of the road, only managing a fleeting glance at Yukino as they passed each other.

"Kamijo Touma?"

The main character of the A Certain Magical Index series always has an ambiguous relationship with Misaka Mikoto.

"I wonder how Kuroko will feel after he finds out about the two of them."

Judging by the time, Index shouldn't have met him yet at this point.

Although Touma Kamijou is a Level 6 Devil Fruit user, his right hand, which is known as "Imagine Breaker," is probably at Level 6.

As he was thinking this, Touma, who was running, suddenly stumbled and fell to the ground, and then a basin of water was suddenly poured down from above.

"Oh no, what a misfortune!"

"..."

Seemingly noticing the girl's gaze, Touma scratched his head sheepishly and hurriedly ran away.

"Although seeing a familiar protagonist gives me a sense of warmth, I'd better not get involved with him, right?"

Yukino didn't want to be drawn into the magic-themed storyline.

Following Misaka Mikoto in the short term is perfectly fine. What to do after that depends on the situation. If all else fails, different clones can hide in different places, and if an unforeseen event occurs, time can be reversed.

If you have countless opportunities, then you will surely be able to resolve the crisis at least once.

"So be it."

……

The following period was a bit busy, as she received her Tokiwadai school uniform upon entering the school.

"This skirt is really short. Kurohime will have to wear safety shorts."

This isn't really about protecting yourself. After all, at this level of strength, your safety is basically guaranteed, especially since you can cancel the clone at any time.

But one should always be prepared for the worst, and for a girl, this situation is perfectly normal.

In battle, if you accidentally jump and dodge and someone happens to see you, it's always a bit embarrassing.

Honestly, aside from her true self, she really doesn't want to expose herself in front of anyone.

These past few days, Makise Kurisu has fully entered researcher mode, Yukino rested for a day or two before starting to train, and Mashiro couldn't help but start drawing, and even suggested that the original body be sold.

A week later...

"Shall we tour the entire Academy Garden?"

"Yes, invite Haru and Ruiko."

"Understood." Kurohime looked at Misaka Mikoto and suddenly wanted to laugh. They had only known each other for two days, and Misaka Mikoto already had a very good relationship with her. Were they both Level 5? Impossible. It could only be that she was easier to talk to. Besides, Kurohime was very cute and had a good temper. It was normal for a girl to accept her.

The Academy Garden is a gathering place for girls, and the schools inside are basically all elite schools, which are the young ladies in the eyes of Haru and Ruiko. Commoners can't even get a glimpse of it, let alone enter.

Kuroko and Misaka Mikoto arrived at their destination. The palace-like building with a touch of Western fantasy style immediately caught Kuroko's eye.

"I don't know why, but I always feel like there's something very important I haven't done."

Standing by the roadside waiting, Kuro-tomi frowned.

What is the most important thing when you come to the world of Railgun?

"What's wrong, Kurohime? You seem to be thinking about something?" Misaka Mikoto looked over with a puzzled expression.

"Huh? Was my expression that obvious?" Kuroko was taken aback.

"Ah."

Misaka Mikoto nodded, while Kuroko next to her chuckled, "Why don't I realize how much attention Onee-sama is paying to you?"

"LieLie, you're so pitiful, spending every day in a life of jealousy and being rejected in your pursuits."

Kuroko Shirai's tone was mocking, which made her even more annoyed.

"What did you say? My sister... how could she..."
