(A/N: For those wondering why it took so long to update, this is why. You'll see what I mean when you read the chapter. It's one thing for this chapter to be 5,000+ words long, but it's another thing when considering how many things I had to look up to make sure this made any kind of sense in some way, and after checking multiple times, I still wouldn't be surprised if I made some kind of error or mistake. By the time I was 2,000 words into this and realized what I was doing, it was too late to back out, so I went all in with it. This is for those who like scientific explanations for quirks, and for those who might've been looking forward to an explanation about "her" quirk. You'll see what I mean. I hope you enjoy.)
[31: The Biggest Physics Lesson Yet. It Makes No Sense!]
Iida closed and opened his hand. "This feels a lot better already. The doctors said there was a possibility of having permanent nerve damage."
"Yeah, well, technology is an amazing thing. The nanobots are repairing damaged nerve sheaths and accelerating axon regrowth. A few more injections and you'll be as good as new, Iida." Eleanor said as she withdrew the drone that was treating Iida's injuries with nanobots.
"Thank you. By the way, just how much damage can be healed?"
"Well, theoretically…nanobots could help to achieve biological immortality. It could also remove biological aging and any pathogens."
"Could my brother be healed? Could he return to hero work?"
"Yeah, absolutely. Nanobots, along with physical therapy, will make him as good as new."
"Eleanor, please, help him." Iida was practically about to bow as much as he could, but Eleanor stopped him.
"Whoa, Iida, calm down, you don't gotta beg me or anything like that. And I can't just go to his hospital room and help him. First of all, talk to him about it. Second, talk to Recovery Girl about it; she's the medical person here. Recovery Girl can at least start the process of approving the treatment. Of course, the final approval comes down to your brother. Everything can be set up and approved, but it won't matter without his permission."
"I see. Thank you, Eleanor.
"No problem, I'll see you in our classes later."
Iida left, leaving Recovery Girl's clinic empty. Just as Eleanor was about to relax fully, a cheerful voice entered the office.
"Eleanor!" It was Mina.
"Mina? What brings you here?"
"I may have…had an accident when using my quirk."
"Can you explain?"
"So, Ochaco came to the other girls and me a bit after the sports festival and explained how you helped her find a different way to use her quirk, so I tried thinking of things on my own, but I don't think I can ever come up with anything as well as you could. Can you help me?" Mina showed a little burn on her hands.
"So..you want me to do the same thing to you I did to Ochaco?"
"Yes!"
Eleanor let out a sigh and pinched her nose at the thought of having to do this again. "I'll put this nicely. Hold out your hand in the meantime." Eleanor summoned another drone and started to inject nanobots to heal Mina's burn. "Will you be able to understand? Did you even understand what Ochaco told you when she explained what I said about her quirk?"
"Um..I'll try my best!"
"Alright, someone told me trying your best is sometimes enough. Okay, let's start simple. What's your quirk and explain what it does."
"My quirk is Acid. I can control the viscosity, acidity, and solubility levels of it as well. And if I use it too much in a short time I lose resistance to the acid."
"Mina, do you even know what that means?"
"I read it in a textbook."
Eleanor let out a small sigh. "Alright, good enough. First of all, based solely on what you told me, your quirk is not 'acid.'"
"Huh?" Mina blinked. "What do you mean?"
"Your quirk Your quirk is closer to real-time biochemical synthesis."
Mina stared at her.
"If I wanted to sound extremely nerdy about it, your quirk is programmable biochemical synthesis and secretion with molecular-level control."
"..." Mina stayed quiet. She raised a finger. "I think I got about…one of those things."
"You should be a little familiar. I'm sure you've covered chemistry in your general science class or something." Eleanor realized it may have sounded a bit too complicated, but she trusted the Japanese school system.
"Um…I wasn't exactly the best at it." Mina admitted.
"Not a problem. Let's break down the problem," Eleanor continued. "You said you can control viscosity, acidity, and solubility."
"Yeah."
"Each of those properties depends on different molecular factors."
Mina nodded as if she understood. Eleanor was a bit doubtful she did.
"Acidity depends on hydrogen ion concentration and chemical composition. Viscosity depends on molecular structure, polymer length, and temperature. Solubility depends on polarity, intermolecular forces, and solvent conditions."
Mina nodded slowly.
"If you can adjust those at will, then your body must be controlling molecular structure and chemical bonding in real time."
Mina stopped nodding and just stared at Eleanor.
"Which is…absurd to put it nicely."
Alright, so I'll cover the main topics, because there's way too much to talk about. The biggest red flag is the ability to control the liquid's viscosity, acidity, and solubility. Let's break it down. Acidity depends on hydrogen ion concentration and chemical composition. Viscosity depends on molecular structure, polymer length, and temperature. Solubility depends on polarity and molecular interaction. You said you can control these at will, which would imply control at the molecular bonding level."
"Uh…okay?"
"This violates several major biochemical constraints. Things like reaction pathway limitations, and energy requirements for bond rearrangement. Or at least, that's what I can name on the spot. I'm sure there's more. Now, about your resistance to acid."
"Yeah, if I overuse my quirk I start losing resistance," Mina said.
"That weakness doesn't make much sense in the way you described it." Eleanor said.
"Oh."
"Acid-resistant tissue doesn't simply 'turn off.' It would require continuous repair mechanisms, buffering chemicals, and rapid cellular regeneration. If not, damage would accumulate irreversibly." Eleanor pointed to Mina's horns. "However, your anatomy gives us clues. Acid-resistant keratin structures like, what horns are made of, would make sense. You'd also need thick epithelial layers, mucus barriers, and extremely fast cell turnover. This tells us that your body does have some of the adaptations needed for your quirk to work."
Mina touched her horns. "So, these actually help me?"
"Well, not the horns specifically, but the material they are made of. So…probably."
"Okay? So, what does any of this mean?"
"At the minimum, it means your biology and anatomy are very different from a normal human. It'd be the only way for your powers to work."
"And if I didn't have these changes to my body?"
Eleanor answered immediately. "You'd be dead."
Mina froze. "Immediately?" Mina asked.
Eleanor thought for a moment. "No, not immediately. It would take a few minutes."
Mina was silent. "What?"
"I mean it. First, there's your nervous system. To control pH, chemical composition, volume, flow rate, and all that stuff for your acid, you'd need extreme biochemical sensing, rapid intracellular synthesis, and enzyme systems far beyond known biology. Let me put it this way: there is no organism on Earth that can dynamically switch between slime and industrial acid in seconds, with the sole exception of you, apparently. Second, there is the problem with your internal pH levels. Normal human pH levels are around 7.35 to 7.45. When you produce large amounts of acid, your internal buffering systems must compensate. If they don't, you'd go into metabolic acidosis, which quickly leads to organ failure and then death, but as we can see, you're alive. So this means the acid your produce is made externally in specialized glands fully isolated from bloodstream chemistry, which would require crazy anatomical redesign, which we discussed earlier."
"So…like a snake?" Mina asked.
"Yeah, kind of like a snake. See? You do understand this."
Mina felt good about getting something right. "So, that's what my quirk is? No other problems?"
"Oh, there's a lot more. Those are the main ones. There's conservation of mass, since your acid has to come from somewhere. Energy accounting, biochemical reaction feasibility, tissue durability limits, heat of reaction thermodynamics, diffusion and reaction kinetics, atmospheric chemistry effects, internal pH homeostasis limits, and probably a lot more."
"But my quirk does work! So, you're wrong! Maybe?"
"Well, surprisingly, you do have a few things going for you. That burn you came in with earlier is a good sign that your quirk does respect science to some degree. Strong acid reactions release heat, which means your skin must tolerate radiative heat from exothermic reactions. And if overused, burns occur, tissue denatures, and protective mucus depletes. So, your drawback is now more scientifically friendly under this framework. And there's the horns from earlier."
"So, my quirk is actually scientifically right?"
"No, absolutely not. There are still a lot of things that are unexplained. Like, you'd need to be eating or drinking a lot more. If you make 1 liter of acid, you'd need to drink 1 liter of water, at least. Most of it is biological, but unless we open you up and examine you from the inside, we won't know. Or we could use an X-ray, or some other kind of scan to view inside you, but there's no need to go so far."
"And what does this mean for my quirk? How can I use this knowledge?"
'Well, unlike Ochaco, you'd just do more of the same as you are now. I can't think of a way to exploit this knowledge. So, you're already using your quirk as well as you can."
"So, I can't do much more than I'm already doing?"
"Just drink water. A lot of water."
"That sucks. But hey, since you're so good at this, can you analyze Star and Stripe's quirk? You know, since you met her?"
"You can't be serious."
"Yeah, come on, it can't be that hard." Just then, the bell rang. "Oh good, you can do it in front of the class! Come on!"
/\\//\\//\
While class was in session, Eleanor was engrossed in her notebook. Seemingly incoherent scribbles and markings took up multiple pages. Midoriya looked over to see what had her so focused, and he didn't know what to make of it. The only thing that made sense was a series of arrows pointing to the word "ENERGY SOURCE?" which was circled multiple times.
"Hey, Eleanor, you okay there? What are you even doing?" He whispered.
"Midoriya, do you know what quantum field equations are?"
"I'll stay quiet."
The class continued until the bell rang. Eleanor sighed, hoping she really didn't have to do this.
"Hey, everyone!" Mina said.
'Oh no.' Eleanor thought to herself.
"So, you know how Eleanor helped Ocacho with her quirk? Well, she did the same thing to me and it was fun, but confusing."
"Isn't that what Midoriya does?" Kyoka said.
"No, but she explains all the science behind it! She went all crazy when explaining my acid quirk. Turns out, I'm weird or something," Mina said.
"Weird when compared to a normal human, not within the context of your quirk," Eleanor clarified for everyone.
"Anyway, since she met Star and Stripe, I thought she could explain it to everyone!"
"Is this a good use of time?"
"Just think of it as a science lecture! Eleanor was first in the midterms, wasn't she? Think of it as a lesson from the top of our class and from our representative."
"Yeah, this could be good. Learning about the quirk of one of the most powerful heroes in the world could help us in the process of understanding our own quirks better." Iida said.
'No! No! This isn't supposed to be happening! Any sane student wouldn't want to stay in class after it ends!' Eleanor was panicking inside. 'Oh, gods, please help me.'
"Come on, Eleanor, you're up! Explain Star and Stripe's quirk scientifically!" Mina was excited. Maybe too excited. Perhaps she didn't understand what she was asking of Eleanor.
Eleanot let out a sigh and ran her fingers through her hair as she made her way to the front of the class. "Before I start, who's the deity of wisdom in Japan or in the shinto religion?"
"It's Omoikane," Momo said.
"Good, because we're going to need divine assistance with this. Also, we don't have to do this, you know? Class is over, and I'm sure all of you would rather leave." Eleanor tried to save herself.
"Nope!" Mina exclaimed.
Eleanor rubbed her eyes and then picked up the chalk. "Well, let's get started. First off, we'll start with what Star and Stripe's quirk is." Eleanor started writing on the board. "Her quirk, New Order, allows her to impose a rule or law on anything she touches. Now that that is out of the way, let's get into the science."
The first thing Eleanor wrote was the first law of thermodynamics. "As we know, energy can not be created or destroyed, only transformed. This is perhaps the most fundamental law in all of physics, but New Order can also do things like make someone stronger, alter the properties of air, change the durability of objects, and much more, all of which require energy. If she made an object stronger, the energy from somewhere, so she's either making energy come from nowhere, or she has access to some kind of external energy reservoir that is beyond the current understanding of science." Elenor wrote a line connecting to a circle. In the circle, she wrote, "Energy source?" "The biggest problem is energy."
Eleanor wrote "Conservation of mass" next. "This law tells us that mass cannot be created or destroyed in normal circumstances, only transformed, rearranged, or converted into energy. This is similar to the law of thermodynamics. As mentioned previously, her quirk can alter density, change structure of materials, or modify the physical properties of the air. If she made air solid enough to hold a shape, then the molecular structure must change. And this means atoms are being rearranged without chemical reactions. This violates conservation of mass unless her quirk can directly manipulate atomic structures, which requires energy." Eleanor drew another line back to the "Energy Source?" circle. "So we have the same problem again."
"Oh, I think I got it! This is like when I make my acid, right?" Mina said.
Eleanor turned around and pointed the chalk at Mina. "Yes. Your body most likely converts water and nutrients into acid molecules, and it has to follow this law. If you make 1 liter of acid, an equivalent number of atoms or molecules must come from somewhere. Good job, Mina." Eleanor said as she turned back around.
Mina nodded. She was learning! She might not do so badly on the written part of the final exams after all!
Eleanor started writing again while explaining. "The second law of thermodynamics. This tells us that entropy always increases in an isolated system or remains constant; it never lowers. In other words, systems become more disordered over time. New Order can instantly organize matter into stable structures, which means it can reverse entropy."
"And to reverse entropy, you'd need energy input, right?" Momo asked.
"Yes, Momo, exactly. Which leads us back to the same problem of energy." She drew another line to "Energy Source?"
"So, what's the solution? I mean, her quirk clearly works, so there must be some kind of framework that fits, right?" Momo asked.
"I'll get there, just give me a moment." Eleanor said as she moved on. "Since we've been using air as an example a lot, let's focus on that. Can anybody tell me how many molecules are in the atmosphere?" Eleanor turned around and waited for an answer.
"Um…a lot?" Kaminari said.
"Well…that's not entirely wrong, but I'm looking for a number. Anybody?" Eleanor asked, but no one answered. "Alright, well, there are a few answers. For the total atmosphere, it's around 1.1 × 1044 to 1045 molecules. For one cubic meter, there are around 2.5 × 1025 to 2.7 × 1025 molecules. As Kaminari said, it's a lot, which brings this problem." Eleanor wrote "Particle Count" on the board. "Controlling air precisely would require keeping track of an astronomical amount of molecules simultaneously, which has to be done by her brain, which means her brain has a computational capacity far beyond any human biology or supercomputer, maybe even a quantum computer. And for her brain to process all that information, she needs energy! So, once again, we're back at energy!" Eleanor raised her voice as she drew a hard line across the board back to "Energy Source?"
"I think she may be losing it," Kaminari whispered to Kirishima as he saw how Elearnor seemed to be spiraling.
"Wait, Eleanor, so what you're trying to say is that New Order requires either an enormous amount of energy or a change in the laws of physics themselves?" Momo asked.
Elanor let out a deep breath in and out. "Yes, Momo, if the energy problem can be solved, it would help tremendously. You'll notice that it all goes back to energy." Eleanor started writing again.
"Wait, what if she imposes a rule that an object can't break?" Midoriya asked.
Eleanor pinched her nose. "Oh, come on. It would mean the material would have to endure infinite stress, which violates materials science. And don't get me started on working with infinity. If you think your algebra lessons are bad, oh boy, you have no idea what's coming."
"Wouldn't it be calculus?" Momo asked.
"Not really. Calculus isn't only about infinity, but it does play a role. Mostly in determining limits of a function as it approaches infinity, the end behavior of polynomials, and series convergence, but that's off-topic. Let's get back on topic." Eleanor started writing again. "We now exit the realm of physics and enter the realm of information theory and cognition." On the board, the words "Identity of objects" were written. "New Order requires naming the objects, which implies the quirk understands identity, classification, and conceptual boundaries. So, her quirk requires a semantic understanding of what something is, which further implies the quirk is interpreting language and meaning. I can't even begin to explain how strange this is."
"Just say she's strong and move on already!" Bakugo shouted.
"Hey, some of us are actually learning here!" Mina responded.
"You don't have to be here, Bakugo. Like…class has ended. Any of you are free to just leave." Eleanor said.
"Yeah, but this stuff is actually really interesting. I had some doubts about this thing, but now I'm focused on it." Kirishima said.
"Alright, now that we've established what's wrong, we can move on to the possible explanations of how her quirk actually works. And we'll start with extreme matter manipulation, or atomic control. New Order could allow her to manipulate atoms and molecules directly. If she can do this, she can change density, alter material strength, restructure air molecules, and reinforce her own body. However, energy becomes a problem yet again, because you need a lot of energy to rearrange the number of atoms that Star and Stripe does, but that will come in later. This also doesn't explain the reaction pathways needed to rearrange atoms, and the speed with which she does it."
Eleanor continued as she wrote, "Environmental Energy Extraction" on the board. "Her quirk might get the energy it needs from the environment. Perhaps thermal energy from the surrounding air, electromagnetic radiation, gravitational potential energy, or maybe ambient chemical energy."
"Okay, but even if it does, it would still require a lot of energy. The scale would be enormous." Momo said.
"You're right. The scale of energy needed would cause massive temperature drops, shockwaves, and atmospheric disturbances. And last time I checked, America isn't having disasters caused by Star and Strip using her quirk."
"So, what now?" Momo asked.
"I got it." Eleanor wrote another thing on the board, "Localized physical law override," before she continued. "Her quirk may be temporarily rewriting the physical laws affecting a target. This would explain instantaneous effects, lack of visible energy input, and other seemingly impossible behaviors." Eleanor saw what she wrote, but then let out a frustrated sigh. "No, this doesn't work either! It doesn't explain the spoken commands! As discussed previously, her quirk somehow understands grammar, meaning, and the identity of objects, which implies semantic cognition. There is also the problem of object identity! Her quirk must determine what an object is, where its boundaries are, and whether the name matches; that's not physics, that's philosophy of language! Sure, her brain could do it, but even if we just accept that part, it just goes back to the insane energy needed for a brain to process so much information!" Eleanor raised her voice again as she kept writing while explaining. By now, the chalk was more than halfway used up.
Eleanor calmed down a little. "I'm sorry about that."
"No, no, I think we understand. I think Momo is the only one that can keep up with all of this." Mina said.
"I have a vague understanding of this so far." Momo responded.
"Good thing we have more science in our arsenal. And if you are barely keeping up, then this is the part where everyone will get lost, even with my help in helping you understand." Eleanor said she wrote "Quantum Fields" on the board. "Yes, we're getting into the quantum level; that's how you know things are getting bad."
"Quantum?" Kaminari was scared. Regular physics was bad enough, but now it's quantum?
"Look, I'll try to help, but even I don't understand."
"Even you don't understand it, Eleanor?" Momo asked.
"More like no one understands it. If any of you ever meet someone who says they understand quantum mechanics, they are lying and are frauds. There was this guy called Richard Feynman from the 20th century, which might as well be ancient history for our time, who said some quote about it. Anyway, enough about him, he was kind of a fraud and a big jerk, so don't take him too seriously."
"Okay, so what are quantum fields?" Momo asked.
"I'll make this simple." Eleanor somehow found an empty spot on the board. She drew a straight line across. "Everything in the universe—matter, energy, particles—comes from underlying quantum fields." She tapped the line. "Think of reality as a surface," She drew a little bump on top of the line. "Particles are just small disturbances, represented by the bumps on the line, on the surface."
"So we're all just bumps or whatever?" Mina asked.
"Yeah, basically." Eleanor continued. "Now, let's apply this to Star and Stripe's quirk. As we know, everything comes from underlying quantum fields and the interactions that occur at this level. This includes forces like gravity, electromagnetism, and the strong and weak nuclear forces, which, as you should know from your science classes, are the four fundamental forces of the universe. So, if you can change or manipulate these fields, you can change the rules of reality. In other words…reality manipulation, which we can safely assume is what she's doing. Controlling quantum fields is an explanation for this. But here's the problem. If she's manipulating quantum fields, then she would need to control an amount of interactions that can't be meaningfully quantified."
Eleanor wrote another thing on the board, "Heisenberg uncertainty principle," before she explained it. "So, in the ancient times of the 20th century, this guy called Werner Heisenberg proposed that we can not simultaneously know the position and momentum of a particle with arbitrary precision. So, no matter how good the technology is for quantum measurement, we can never know. It shows the inherent randomness at the quantum level. Now, knowing this, and taking into account the proposal of Star and Stripe's quirk controlling interactions of quantum fields…controlling every particle with precision is impossible unless she ignores quantum mechanics. And then of course…" she drew a line back to "Energy Source?" "...there's the same old problem of energy source." Eleanor ran her hands through her hair at the nemesis that was the energy source.
"I think I understand. So, would the scaling also be a problem? These quantum interactions take place at the sub-atomic level, and Star and Stripe operates at…well, normal levels like us." Momo added fuel to the fire.
Eleanor sighed. "Yes, Momo, good catch. And good, you're learning. No offense to everyone else, but you're the only one I expected to somewhat grasp all this."
"And how would you explain the information problem? The whole semantics thing?" Momo asked.
"Well, since we're on quantum fields and interactions, I think I have an explanation for that." Eleanor wrote "Information → Language → Mathematical Model" before she started explaining. "Alright, so we know quantum fields create particles, and those particles create physical systems like atoms and molecules, and the physical states of these systems function as an encoding of information. In other words, everything physical also contains information," she said. "Position, structure, identity, those are all forms of information encoded in matter. So, if her quirk reads that information, then it could identify targets, interpret structure, and apply changes precisely. This would explain how she identifies objects, why naming matters, and how rules are applied."
"Is this how the language works as well when she has to speak out her rules?" Momo asked.
"That's the next part. I'll explain how language is translated into a way her quirk is able to understand. If you have ever used an AI or a Large-Language Model, you'll understand this, because they're kind of similar. When you type a prompt into an AI, the AI breaks the text down into smaller units called tokens. These tokens are mapped to high-dimensional vectors, where each word becomes a unique numerical vector in a vast space. The AI then uses geometry to compare distances and directions between these vectors to understand and generate text. In short: Words, sentences, and documents are turned into vectors, which allow the AI to process language as linear algebra rather than human meaning."
"So her quirk does the same thing?" Mina asked.
"Not quite, or more like I don't know, but the concept is similar. Star and Stripe's quirk may translate spoken language into structured representations. Like an AI, it converts meaning into mathematical instructions. However, on its own, it fails to explain a few things. One thing is that information does not equal causation. Just because you know how a system works doesn't mean you are able to change it. Another thing is that meaning is not a physical property. If Star and Stripe were to use words like 'strong,' 'unbreakable,' or 'this object,' those are not measurable quantities; those are concepts. Oh no, which might imply her quirk has conceptual properties."
"Wait! I think you got it!" Momo exclaimed.
"Explain." Eleanor said.
"Look, I don't get it exactly, but from what you said about quantum fields and information. Controlling quantum fields would provide the mechanism for change, and the information theory you just gave would solve the object and language problem. Can't these theories be combined?" Momo said.
Eleanor smiled. "That's what I thought at first, but…there's the energy problem. Even if you assume many things are very generous, you still need energy."
"Why not just use quantum energy? Or is that even a thing?" Kaminari said.
Eleanor scoffed a little at how absurd this was getting. "Well…kind of, but…here, let me explain. Eleanor wrote "Quantum Fluctuations" on the board. Let alone the class, even Momo felt a bit uneasy at seeing the word. "Alright, don't be scared. Even in a perfect vacuum, energy doesn't stay at zero." Eleanor drew a horizontal line and then small spikes on the line. "At these scales, energy briefly appears and disappears."
"Huh? So, like, they come out of nowhere?" Mina asked.
"Wouldn't that violate the first law of thermodynamics you mentioned earlier?" Momo asked.
"Whoa, whoa, calm down a little. Let me address that. Quantum fluctuations appear to come out of nowhere, but they don't. They come from something called, and I promise this is the real name for it, quantum foam. Quantum fluctuations are 'virtual' particles that appear and instantly destroy each other. Now, despite what it sounds like, it doesn't violate conservation of energy, because of something mentioned earlier, the Heisenberg principle. These fluctuations are temporary and result in a net-zero energy gain."
"Okay, if I understand it right, then it also fails to explain the energy problem?" Momo asked.
"Yes. Quantum fluctuations are too small and too short-lived, and even if they could be harnessed, you need to control and stabilize an infinite number of these particles. And even if we assume New Order can do all this, quantum fluctuations are completely random, like truly random, which means they can't be controlled at the scale that New Order operates at. In fact, any proposal involving using energy from quantum effects or interaction runs into the same scaling and control problem. And even if you assumed she could, there's a limit on the ability of her brain to compute everything."
Eleanor took a step back and looked at the board. What started semi-understandable seemed to devolve into a complete mess, except for all the arrows pointing to "Energy Source?" on the board. It all came back to a source of energy. The chalk in Eleanor's hand was hanging on by a thread. She stood there in silence, trying to come up with any possible method of how Star and Stripe got the energy needed for her quirk to function. She is willing to let every assumption pass if she could only solve the problem of the energy source.
"Ah, damn it all!" Eleanor threw the chalk at the board. It crumbled into pieces.
"Are you okay, Eleanor?" Momo asked.
"I think I have it. I've come to the only reasonable scientific conclusion that explains Star and Stripe's quirk. The only scientifically honest conclusion."
"And what is it?" Mina asked.
Eleanor sighed. She looked at the entire class seriously. "It's magic; there is no other possible explanation, or at least none I can come up with on my own."
"Magic? Come on, that can't be it. You've been so scientific this entire time, and you end up at magic?" Momo said
"You try coming up with something better, Momo. I…I can't do it. I can't explain how Star and Stripe's quirk works without letting ridiculous assumptions pass and breaking every major branch of physics. Therefore, it is magic."
"Well, um, at least we learned something?" Kaminari asked.
"Yeah, I think we did." Iida said.
"Eleanor, quick question. Why are you here? Like, why have you not advanced a grade, or something, when you're clearly ahead of us in most subjects?" Mina asked.
"Well, I don't know everything. Let's just say that…I have some prior experience with all this advanced stuff. Also, math and science are hardly the only subjects taught at this school; that's just part of it. I may have placed first in the midterms, but I still studied, though I will admit, maybe not as hard as some of you."
"Hey, maybe you could teach us what we don't know?" Kaminari asked.
"Yeah, with the final exams coming up, we need all the help we can get." Mina asked.
"If it's science and math, sure, I'm more than happy to help. We can study at my place." Eleanor said.
"Oh, yeah, I wonder where you live. Do you live in some apartments provided by the school? You know, since you're a foreign exchange student?" Midoryia asked.
"Hmm…I guess I never told you all where I live. I thought some of you would've already figured it out. How about this? We can hold a study session, and I'll show you where I live." Eleanor said.
"Deal! I'll make sure to get a good grade on the finals!" Mina asked.
"I need some help with math as well," Kyoka said.
"Alright, it's settled. We'll set up a date for the study session," Eleanor said. With that, Eleanor ended what was perhaps her biggest explanation, combined with a science lecture, that also taught the class some things.
