Chapter 5 - Vector Manipulation

"This could be a problem."

"Is this your new ability?" His mother questioned.

"Yes, it seems that it works automatically." Izuku started to mumble about the new possibilities this new power could bring him, to never be hurt again, sure he is happy to have something like that, but it also did not allow anyone to reach him, not even his mother.

"Can't you turn it off?" Inko was starting to get slightly worried about her son's new power.

"I'm not sure, it seems to be active at all times, I'll figure something out." He stated, trying to ease his mother's worries.

Izuku spent his entire weekend figuring out his new ability, and writing it down on his personal hero notes, he also wrote down the equations that it takes for all of his quirk powers to work, he never once thought that a notebook about himself would get almost completely filled so quickly.

It turns out that he still could touch other people, as long as he is the one initiating the action, he also learned that he could not turn it off, but he could stop it temporarily, as long as he kept focusing on the equations, not letting them finish, people would be able to reach him, but the moment he stops focusing on it, his field would be active again, even when he's asleep, the brain never rests after all.

DAGOBAH MUNICIPAL BEACH PARK

Izuku was very excited, his training with Togata was about to start, he could finally train with his quirk without having to worry about repercussions from the adults or pro heroes. He reached the beach rather quickly, it seems that Togata and Mr. Yagi were already there.

"You're here, good, did you throw any vault up in the air on the way here?" Togata jokingly asked, getting a chuckle out of Mr. Yagi.

"W-What, no, that was the only time I did such thing." Izuku quickly defended himself, getting Togata to laugh at his reaction.

"All right." Mr. Yagi spoke. "We are here to help you train with your quirk, in exchange you'll help Mirio to clean this beach, how about we start?"

Both of the younger boys nodded eagerly and started to move the trash, Izuku was using his quirk while Togata was doing everything physically, when Izuku asked why he simply said that his quirk was not fit for such things and that he needs to build his physical strength, he also recommended Izuku to do the same since heroes could not always rely on their quirks. Izuku will start doing that as well but not right now, for the time being he is focusing on his quirk.

At Mr. Yagi's suggestion Izuku was focusing on moving multiple objects at once, it was a bit difficult on the beginning since it required more equations and better focus on his part, if he makes one mistake on his equations his quirk would not activate, his calculations must always be precise.

The boys would load the trash into a small truck, once completely loaded, Mr. Yagi takes it to an actual junkyard.

The three of them would do a lot of small talk during their work, most of it consisted in Togata throwing goofy comments about many subjects, Izuku was a bit awkward around them, even if they're helping him they're still strangers. After a couple of hours he was starting to get more comfortable around them, and them decided to ask something that was on his mind since the day he met them.

"...Togata, why did you decided to help me?" Izuku asked with a serious tone. "You barely know me."

Togata chuckled at the boy's seriousness, "You've got a great goal in mind, and needed help to achieve it, when a hero sees someone in need they're supposed to be nosy and help them out." Togata spoke with a big smile on his face that reminded Izuku of All Might.

After that answer Izuku became very relaxed around them, during one conversation where Togata was asking questions about himself, Izuku told him about his hero notes, Togata promptly asked Izuku to show them to him, unfortunately the only notebook Izuku had on hand was the one about himself. He denied at first but after a barrage of requests he relented and showed the older boy his notes.

Togata chuckled a bit once he read the possible hero names, which made Izuku hide his face because of the embarrassment, but stopped smiling once he saw how detailed those notes were, 'If the notes he have on other heroes are as detailed as these, I hope none of them ever reach a villain's hand.'

The day passed rather quickly, it was starting to get dark, so the trio decided to stop and continue on the next day.

"Young Midoriya, I could not help you much with your quirk since I do not understand it very much, but I know someone that can, would you mind lending me those notes? I'll properly return them tomorrow." Asked Mr. Yagi.

"...Uhh, sure." Izuku accepted and gave the man his notebook, he was now even more embarrassed because someone else would read his notes, but if it could help him with his quirk it did not matter.

"Thank you, I'll return this to you tomorrow, now be careful on your way home, it's getting dark."

"Yeah, thanks." Izuku picked up his backpack, said his goodbyes and went home.

"Who are you taking those notes to?." Mirio asked his mentor.

"To the principal, I'm sure he can figure this out."

NEXT MORNING AT U.A.'s TEACHERS LOUNGE

Two people sat in chairs, directly opposing each other.

"So, what do you want me to look at?" Said a childlike voice that belonged to a person that looked like a combination of dog, mouse and bear, the principal of U.A., Nedzu.

"Theses notes, they are detailing a quirk from a late bloomer that Mirio and I met last week, I am hoping that you could help us figure out what exactly his quirk is." Toshinori said handing the notebook to the principal.

"How did you meet this boy?" Nedzu asked while looking through the notes.

"I was taking Mirio to the Dagobah beach to start his training, then I saw a safe going up in the air, I quickly ran towards the beach and saw the boy standing in the middle of a lot of scrap, I knew exactly at that moment that he was the one who did it, I promptly scolded him for his actions. When hearing his explanation I saw that he was just trying to learn about his powers, Mirio offered himself to help the boy while the boy helps him with his task. After talking to him that day, and spending yesterday's afternoon with him, I saw the heroic spirit on him, so I'm trying to help him with his quirk as well." Toshinori explained.

"I see, that was certainly reckless on his part, but from what I'm seeing from these equations, he knew exactly where that safe was gonna land, so it would never hurt anybody." Said the principal slightly impressed by the detailed information on the notebook, and the advanced equations written on it.

"Do you understand how his quirk works?" Toshinori asked curiously.

"Indeed I do, he manipulates the vectors." Nedzu answered.

"Vectors?" At the mention of that word, Toshinori remembered his physics class on his old school days.

'

"Position and momentum, that's what his quirk affects." Nedzu started speaking in a teaching tone."He calculates the laws and concepts of what he is about to affect, then changes the values of the vectors that will get him the result he wants, his quirk then translates the new changed values into reality, but I'm interested in his defensive redirection ability…"

"He has no such thing." Toshinori said, being confused by the principal's last statement.

"Oh, the field that stops things from reaching him is not actually stopping anything, it is redirecting the kinetic energy away from himself and away from the person trying to reach him, I guess he did it unconsciously to not hurt the other party, if he simply reverse the direction of what is trying to reach him and then increase it's magnitude, one could be seriously hurt by simply trying to touch him." The principal continued speaking in a teaching tone.

"From what I see in these notes he can manipulate any vector that he understands, if he does not understand he simply calculate it until he does, the more he learns the more he can do, if he keeps going like this, in the future, we could say that he wields the power of god, since there are vectors in nearly everything in this universe."

"T-That's incredible." Toshinori was shocked.

"Indeed, with such power he could be the next number 1 hero." Nedzu spoke while returning the notebook to his fellow hero. "Does he plan to come to U.A.?"

"Yes, since its the same hero school that I graduated in, the boy is a great fan of mine." Toshinori chuckled a bit, remembering the possible hero names written in that notebook.

"I see, the only way his quirk can truly improve is by doing calculations faster, which he already does naturally the more he uses it. If he truly wants to do more than just throwing objects in the air, tell him to actually read a book on physics instead of simply solving the mathematical problems without understanding them, also, tell him to read on chemistry and biology, physics is the most important for his quirk, but the other two can help as well." Nedzu finally finished speaking with his teaching tone.

"Thanks for your help, I'll tell him later." Toshinori bowed a bit towards the principal.

"No problem, one last thing, when he decides to register his quirk, tell him to register as 'Vector Manipulation' since that's the best way to describe it."

"I'll tell him, thanks again."

AFTERNOON AT THE BEACH

"...Vector manipulation." Izuku was a bit amazed at the new info Mr. Yagi gave him about his quirk, the person that he took his notes to seems to know exactly how his quirk works.

'I never thought that I could improve my quirk by simply reading, now that I remember I truly did only solve the problems in the books, I did not read any of them, that was a mistake on my part.'

"That's amazing Izuku." Togata barely understood a word of the technical terms that his mentor used, but was still just as amazed as Izuku was.

"Indeed, your power is incredible young Midoriya, but you must use it responsibly, such power could be really destructive, now, let us continue our work here, we still have a beach to clean,"

""YES SIR""

A/N:

Sorry for the delay, life has been a pain lately, I'll try to make the next chapter come out quicker, someone pointed out the mistake I made about Izuku's protection, tried to fix that in here.

Reviews and criticisms are welcome.
