Chapter 01 - From Quirks to Science

It was just another afternoon at the UA dorms.

Outside the windows, the sun was setting early, a characteristic of Mid-November. The majority of Class 1-A was sprawled across the place, doing various activities.

Some students were relaxing on the chairs littered around the common room. Others were in the kitchen, cooking food in preparation for that night's dinner.

One student, Izuku Midoriya, was sitting on the couch in front of the tv. He was furiously writing down every single detail from a recently released All Might documentary.

"Allmightwas220cmtallandweighedapproximately274kgathisprime-"

"Shut the fuck up Deku! Quit your shitty mumbling and let me sleep!" yelled out Katsuki Bakugou, who was laying down on one of the other couches. He was one of the most powerful students in Class 1-A, although his personality left much to be desired.

"Eep! S-Sorry Kacchan!"

"Hey, relax Bakugou. Why don't we go out and do something?" asked Eijiro Kirishima from above him. While not as powerful as some of the other students, there wasn't a single classmate that had negative feelings towards the manly red-haired student.

"Hell no! I'd rather sleep than hang around you, shitty hair!"

Right then, Denki Kaminari walked into the common room and decided to join in the conversation. "Don't worry about him. 'Kacchan' is just really into Midoriya's mumblin-"

"FINISH THAT SENTENCE DUNCE FACE! I DARE YOU!" Bakugou was suddenly sitting up with a deadly glare.

"AH! Don't kill me please!"

Laughs erupted from all of the students who were witnessing this. Bakugou's reactions were always a source of entertainment for the class, even if the language was a bit crude.

"Hey Deku!" shouted Ochaco Uraraka, who was walking down the stairs with Tsuyu Asui. "What's going on?" She took a seat next to Izuku on the couch.

"Kacchan." It was all he needed to say for the two to understand.

"Who is he threatening this time, ribbit?" asked Asui.

"It's Kaminari. I didn't quite catch what he said though…"

"AHHH! I THOUGHT YOU WERE TOO SLEEPY TO DO ANYTHINGGG!" cried out Kaminari, causing everyone to turn to him. It turned out Bakugou was not in a very forgiving mood. He decided to chase the electric-quirked student around the common room, throwing the ocassional explosion with his quirk.

"GET BACK HERE YOU BASTARD!"

"What a mad banquet of darkness," mumbled Fumikage Tokoyami to himself.

It seemed like the chaos would last for a while, if not for the intervention of a certain black-haired beauty.

"Attention everyone! I require assistance preparing dinner tonight. Who wishes to assist me?" asked Momo Yaoyorozu.

"I can do it! As long as you promise that you'll let me-" began Minoru Mineta, before abruptly being cut off by a large slap.

"She didn't mean you, Mineta." Asui refused to let the pervert finish his sentence.

"I'll do it!" declared Rikido Sato. He was considered the unofficial best chef in the whole class. Even Bakugou admitted that the cooking was 'not shitty'.

"Yay! We'll get Sato's sweets tonight!" cried out Ashido Mina, jumping up and down.

Uraraka was overjoyed with this turn of events. "Wow! Isn't this great, Deku?"

No response.

"Deku?" She turned her head to the green haired teen, who was furiously writing down something.

"You're telling me that there was a line of All Might plushies that only had twenty-seven of them made? How could I not know this information?! I'm a failure of an All Might historian! Ok, I need to find anyone willing to sell one!"

Once Izuku had entered into one of his mumbling sessions, the only ways to snap him out were to either have Bakugou yell something or to shake him out of it.

And considering the explosive kid was currently punishing Kaminari, there was only one option Uraraka could do.

"Deku! Snap out of it!" She shook his shoulders for a few seconds.

"Ack!" Izuku's head suddenly snapped upwards. "W-Was I mumbling again?"

With a sigh, Uraraka nodded.

"S-Sorry! It's just that there's so much information on All Might!"

"Hey man, it's alright," chimed in Kirishima. "I think your fanboying of All Might is pretty manly!"

"Thanks Kirishima. By the way, what are we having for dinner?"

"I'm not entirely sure, but Sato and Yaoyorozu are cooking, so it's bound to be good!" exclaimed Uraraka. "There's nothing better than-"

"We don't have enough ingredients to make curry!" cried out Yaoyorozu.

Suddenly, the whole dorm went quiet for a few seconds. Then chaos erupted.

"NOOOO! What do we do?!" cried out Kaminari, who was still being ruthlessly punished by Bakugou.

"That is not very good," Mezo Shoji commented from a random corner.

"Without curry, we won't be able to truly savor Sato's sweets!" Toru Hagakure declared.

"Calm down Class 1-A!" shouted one voice louder than the rest. "As students of UA, we must hold ourselves to a higher standard! Panicking will do us no good!"

That was Tenya Iida, the class representative. With just a couple words, he was able to calm down everyone's shouting.

"He's right. Just crying will not solve our dilemma," said Yaoyorozu. "Someone needs to go out and pick up ingredients. We still have some time before curfew hits."

"I'll go!" exclaimed Izuku, who felt a little guilty about not helping with dinner earlier. "There's a store not very far from UA. It shouldn't take me very long to get the items."

"Perfect! Anyone else want to go?".

"I can come along if you want," Shoto Todoroki offered.

"Thanks Todoroki, but I think I can handle this one on my own. You go help out the others!"

After receiving the list of ingredients, Izuku grabbed his bag and a coat, before running to the teacher dorms. His teacher's name was Shouta Aizawa, also known as the pro hero Eraserhead.

Ever since the dorm system was put into place, students who wished to leave campus had to let their homeroom teacher know and sign a request to leave campus. After all, if a student was missing, it would give them an idea of where they were.

He knocked on the door to the dorms and waited for someone to open the door. It didn't take long, although instead of Aizawa, it was Present Mic who opened the door.

"Oh, hey little listener! What are you doing out here?"

"P-Present Mic! We, uh, r-ran out of ingredients for Curry. I need to fill out a request to go grab some," explained Izuku, stuttering a bit.

"Ah! Don't worry, I'll get Shouta out for you!" Mic closed the door again, which was followed by loud shouting. This seemed to go on for a few minutes, until the door opened again.

Standing there was Mr. Aizawa, who was looking extremely tired, as he always did. "Come in."

Izuku did so, following his teacher to a table. There was a stack of request forms sitting on it.

"Fill out a form. Make sure you're back by curfew. If you aren't, I'll expel you," Aizawa said with a deadpan tone. It caused Izuku to get chills down his back, especially since he knew that Aizawa was serious.

Once he finished filling out the form, Aizawa looked over it to ensure it was completed properly.

"Looks good. See you soon, problem child."


"Meatmeatmeat… here it is!"

Izuku was browsing the store, making sure that he was getting all of the ingredients on his list. He'd already gotten most of what was on his list, with meat being the last item he needed.

After he checked out everything, he began his trek back to UA. The good news was that it was only a 15-20 minute walk, so it should not take very long to get back.

That was assuming, of course, that there were no interferences.

As Izuku was walking, he heard shouting from one of the alleyways next to him. Since it was in Izuku's nature to help whoever he could, he immediately dropped the bag of ingredients and ran in.

In the alleyway, there were three people. One of them, who seemed to have a mutant quirk based off a bear, was lying on the floor, unconscious. The other two had no visible quirks and were rummaging through the person's stuff. Occasionally, they would take out something and put it in their own bag.

"Stop!" Izuku shouted at the two robbers. Both of their heads shot up and turned towards him with a glare. When they saw his face, however, the glare melted into a face of shock and fear.

"I-It's one of the UA brats!" one of them exclaimed. "Why are they here?!"

"Don't know! We have to get out of here!" the other shouted. He stood up and abruptly pulled out a gun out of his pocket. "Walk away or I'll shoot!"

Izuku was a bit shocked at the reveal of a gun, but he forcefully calmed himself down. He was glad that they weren't pointing the gun at the unconscious person, but that could change quickly.

First, he tried to be diplomatic.

"I don't want to hurt you! Just come with me and I promise you won't be badly punished!"

"Screw that! Every hero that ever says that just lies!" the gun holder shouted back.

Well, that didn't work.

Thankfully, he had his provisional license on him.

One For All… Full Cowling!

In the blink of an eye, Izuku knocked the gun out of his hands. Before the gun holder could retaliate, he was suddenly knocked onto the floor by a well-placed kick.

Within a few seconds, he did the same to the other robber. They were both lying on the ground, with Izuku forcefully holding their bodies down so they couldn't get back up.

"It's over! Give up!" He was hoping they would, because with both of his arms occupied, he couldn't call the police.

"Ugh… can't move!" cried out one of the robbers. "Disappearer, you might have to use your quirk!"

"What?! But this guy is just a kid!" the other shouted.

"If you don't, then we'll be caught and rotting in a cell for the rest of our lives!"

"The police and heroes will be on our asses if I use it!"

"But we'll already be gone by the time they find out. Just do it already!"

What are they talking about? The most they could get would be a year for robbery-.

Wait. 'Disappearer'?

"It's not worth it!"

"Do it! Not doing it would mean our lives are over! Think, Disappearer! We'll never be free again!"

Izuku recalled seeing an article a few days ago about a new villain on the loose. While they didn't have an official name, everyone nicknamed them "The Disappearer" thanks to their quirk that made people disappear with just a touch.

Thankfully, very few people have been affected by the quirk, but even just one civilian was too much for the heroes.

"But it's just a kid!"

"A kid that will turn us in with zero hesitation!"

There was little footage of the incidents with Disappearer, but from what footage was available, Izuku deduced that his quirk worked with any contact with the person.

Which means-

After a moment of hesitation, 'Disappearer' finally relented. "Please forgive me, UA!"

Before Izuku could move his arms away from the villain, all of the sound in the world suddenly disappeared.


Izuku tried opening his eyes, but he found that task supremely difficult.

"Ugh… what happened…" Sound was slowly returning to his ears, although there wasn't a lot of noise around him.

It took him a few minutes, but Izuku was finally able to force his eyes open. What he saw was the wall of an alleyway.

Why am I in an alleyway? It confused Izuku, until the memories of the fight he had hit him. He was fighting two robbers and was winning, when-

Disappearer! He must have used his quirk on me! But wait... if I'm here, then it didn't work!

Feeling satisfied that the villain's quirk didn't work, Izuku put all his strength into pushing himself off the ground. He turned his head around, seeing if the three people were still inside the alleyway.

Unfortunately, he was the only one. All that was left in the alleyway was his own body and his bag from school. Dang it! They must have gotten away! I hope the unconscious person got away unharmed.

However, Izuku realized something that was not right. That being: it was nighttime. Which meant that it was past curfew at UA.

"Oh no! I'm going to get expelled for this!" The only way he wasn't going to get expelled was a miracle. Aizawa was known for being quite strict.

Wait… I don't remember there being skyscrapers in Musutafu...

Izuku was staring straight up into the sky, noticing that the alleyway he was in was squished between two buildings that were taller than any near UA. Both buildings seemed like they would belong in Tokyo instead. Which should have been impossible.

"Maybe that's his quirk! The ability to teleport other people! Imagine the possibilities! He could teleport first responders to disaster sites andmakesurethatthepeoplearesafe! Or maybe-"

Before Izuku could fall further into his mumbling spree, he shook himself out of it. No! I need to get back to UA as soon as possible. I'll call Aizawa and explain the situation.

However, when Izuku pulled out his phone and tried calling his teacher, he noticed that he had no service at all. H-Huh? Maybe it's because I'm in the middle of an alleyway?

He walked out of the alleyway, expecting to see the skyline of Tokyo towering above him. While Izuku had never been to Tokyo before, he has seen an embarrassingly high number of All Might fights in the city, so he had an idea of what the city looked like.

"...Huh?"

And Izuku knew for a fact that this was definitely not Tokyo.

"W-Where am I?!"

All of the buildings he could see looked far more technologically advanced than a typical building. Not only that, but there were wind turbines every block.

I've heard of some cities in Europe using high levels of renewable energy, but not to this degree!

It was as if someone took UA and Mei Hatsume's creations and used them to build an entire city. Hell, Izuku could even see some robots cleaning up the streets and sidewalks.

To make his confusion even worse, there was a storefront in front of him that was clearly written in Kanji. Which meant he was somewhere in Japan.

Izuku stood there in shock for a few minutes, his brain trying to process the change in scenery. He was snapped out of this when, in the corner of his eye, he saw a huge laser shooting up into space.

I-I think I'm dreaming. For safe measure, Izuku pinched himself, but it didn't snap him out of any dreams. Fine, I'm not dreaming. I think I need to ask someone where I am.

Right then, he suddenly heard voices from behind him. Izuku whirled his head around, only to see four girls walking down the alleyway. Unfortunately, thanks to the darkness, he couldn't pick out their features at all.

"-it necessary to super make their deaths so slow?"

"It was their fault for pathetically trying to put up a defense against us."

"Wow Mugino, even that's a little bit extreme for you."

U-Uh… This conversation sounds scary! Even so, Izuku was desperate for information on his location.

"H-Hey!" Izuku shouted, causing the girl's conversations to come to a halt. "C-Can one of you tell me where I am?"

All four girl's heads snapped to Izuku, which sent a shiver down his back. His danger sense was blaring right now, urging him to get the hell out of there.

"Oh? And who do we have here?"

"Someone who super hit their head on a rock. Who the hell forgets where they are?"

"Huh, they aren't radiating any AIM fields? That's-"

"Why don't we indulge their request? Basically, he seems weak! There's no way he would be able to beat us like that!"

W-What in the world were those terms? I've never heard of them before. And why am I getting a bad feeling about this?

"...Fine then. You're in Academy City, District 15. Also, you're in an alleyway."

"...Academy City? I've never heard of it." He could not help stating his confusion.

The four girls fell into silence. They were staring at Izuku with expressions of bewilderment.

"Wow, I super think this guy actually did hit his head on a rock."

"What kind of dumbass has never heard of Academy City?!" Suddenly, a bright green orb appeared next to the girl who said that. "Now I'm convinced you're screwing with us!"

"HUH?! N-No! I genuinely didn't know anything!" Izuku was backing up now while grabbing his bag in his hands, prepared to use One For All if things continued to escalate. However, thanks to the light from the floating orb, Izuku could finally make out their appearances.

The girl who said odd terms like "AIM field" had shoulder-length black hair. For some reason, she was wearing a tracksuit, but Izuku did not want to know why, for fear that it would be something terrifying.

The one who suggested telling him his location had blonde hair and blue eyes. On her head was a beret, although he couldn't tell what color it was exactly.

The third girl that told Izuku his location seemed like the youngest one there. All he could see was that she had short brown hair in a style similar to Uraraka.

And finally, the current biggest threat to his survival: the one with the green orbs. She had soft tea-colored hair and brown eyes. Izuku could definitely tell that she was beautiful, enough that she could have passed for a model. If the situation was different, he might have gotten very flustered.

"Sorry dude, but once Mugino gets mad, there's no getting out of it."

A green laser suddenly shot from the orb, nearly hitting Izuku. It was only thanks to his UA training that he was able to dodge such an attack.

Determining correctly that his life was severely at risk, Izuku activated One For All and ran away from the alleyway as fast as he could. This action surprised the four girls, who had assumed that he was too weak to do anything.

"I thought you said you couldn't detect an AIM field, Takitsubo?!"

"I swear he didn't have one!"

While they were arguing back in the alleyway, Izuku had already placed enough distance between him and the deadly girls for them to have a difficult time following.

He was panting slightly, due to how quickly he dashed out of there. Thinking back, it was probably a bad idea to ask four people that were talking about killing.

"But that was a cool quirk! I don't know what it does though. Can it be controlled like a laser beam? How hot does-" Izuku shook himself out of his mumbling sprawl. Focus Izuku! I need to learn more about this place.

Izuku wandered around a little bit, before he came upon a large shopping area. Nearly all of the stores were closed, but there were several screens that displayed information about the weather and any recent news.

"...HUH?!"

It also showed the date, which currently displayed July 28, 2004.

"Is this screen broken?!" Izuku cried out. "T-This is the wrong date!" Combined with the fact that he had never heard of Academy City, he was starting to think of other possibilities.

Am I stuck in a secret city made by the Hero Commission?! Is this a new training facility made by Nezu?! What is this place?!

None of those guesses were correct, although they weren't the worst guesses out there.

"No, I need to calm down. There's definitely an explanation for this. If I was teleported by that villain, then he didn't know what his quirk did," Izuku began mumbling. "None of the other people he teleported have been found at all, which means…"

Izuku's brain suddenly came to a screeching halt. "W-Wait.. No! That can't be right! Come on, I have to be missing something. B-But the date and the city that doesn't and has never existed! It c-can't be that, but the logic lines up…"

After his brain desperately tried thinking of a few other possible explanations, Izuku was forced to reach a single conclusion.

"I-I'm in a different universe."


Hey there. Welcome to a new story!

While I've been a fan of My Hero Academia for a while now, I only recently got into A Certain Magical Index. I really like the whole Index universe and all of the interactions between characters. Then I thought: What if Izuku got sent to this universe?

Normally, these ideas just go away, but for some reason, this idea just stuck with me. Eventually, I decided to go with it and here we are!

A few things to note first.

One: I haven't decided if I'll be using English Sub or Dub terminology. I may do a mix of both, but not sure yet.

Two: Since I'm pretty new to the Index fandom, I haven't fully read up on the lore yet, so the first couple of chapters will likely be slow while I conduct research and actually plan out the story.

I don't quite know how slow chapter releases will be, thanks to school and my writing speed. Also, I may not read reviews a lot because for some reason, I get super stressed before I read a review. I'll probably check on them once in a while so I can get feedback, but it won't be very common.

I just hope that I can do this concept justice.
