My Hero Academia: Blood and Fire

Celestia, Selene, and Izuku found that their parents weren't kidding, they spent the weekend mostly at home, the new one so they could get familiar with their new surroundings, but they did their best to help their parents move the items from the apartment to their new residence. For the most part it was just Hisashi and Inko moving items to and from, but they left a couple of the boxes in places and left instructions for the children to move the items, like dishes and clothing, just to make sure they were involved in moving things into the new house. None of them complained about that, since they knew that it was best to leave some of the heavier things to their parents, plus it gave Celestia and Selene a chance to see Inko's Quirk in action for a couple of moments, when she caught something and floated it over to her. As it turned out her Quirk was the power of telekinesis, or at least the ability to attract small items with her hands, even though it took multiple motions with a hand to pull an item over to her, which meant she likely never trained it.

Of course Hisashi didn't show them his ability to breathe fire, as that was the Quirk he had picked to tell Inko about since he was hiding his true identity from her, mostly because neither of them had the citizen license to use their Quirks in their job, a fact that Selene found to be strange.

He explained that most of the civilians didn't use their Quirks, or weren't allowed to unless they had a license to use their abilities, so if someone wanted to use their power in, say, a construction company they had to acquire one of the civilian licenses to legally be allowed to wield their Quirk. Heroes had their own licenses, to be able to wield and do battle with their Quirks, and without either of those licenses it was considered illegal to use a Quirk, and there were other rules that they had to know for the future, since there was no telling what powers they might obtain. Selene got the impression that her father, the AFO part of him, disapproved of the whole hero society and was actively searching for ways to improve society, all while understanding the information that their father was trying to tell them about. At the same time she also understood that this didn't sit well with others and there might be more people working in the shadows to change society, but did her best to not let on that she knew more than her siblings, since that would spoil the secret she was hiding.

Hisashi also added another bit of information for them, that there were support heroes that needed licenses to do battle, but since they created, maintained, and improved support items for other heroes, like items to increase their power or even make suits for heroes to wear, they also needed a license to be able to work on existing support items.

"I get it: neither of you need your Quirk for your jobs, so neither of you bothered to get Civilian Licenses." Celestia remarked, where Selene nodded her head in agreement, they had thought of the same thing at the same time, though at the same time she realized that their mother was using her Quirk for just moving small things every now and then, something that was fully within her rights, before she sighed, "Just more to learn about in school, I guess."

Selene didn't have much else to add to that, she understood it as well, though Izuku either didn't understand it or did and had no words to add to the talk, though it was good information to have for the future, since none of them knew about all of this stuff, even though there was no telling when it would become important to them. She also had to admit that this was far nicer than she had thought it would be, as having a family was an unknown for her, especially since she had been fueled by Luna's opinions and emotions towards her sister, but now she had the power to form her own bonds. Having her own room was nice as well, since it left her alone with her thoughts, plus having her own clothes was a nice comfort, where she found that her choice was more along the lines of night colors and Celestia, as she expected, went with more daytime colors. She honestly wasn't surprised by that fact, in fact Selene was expecting some portion of Celestia's sun nature to remain at some point, but part of her was hoping that none of Celestia's solar powers manifested.

When Monday morning finally arrived both Celestia and Selene found that there were light blue shirts for them to wear over their bodies, like a coat or something, that had a yellow star with a white center on the left side of the chest area, something Izuku was wearing for preschool. Since it seemed to be a requirement of the preschool the sisters slipped on their new bits of clothing, making them and their brother look like a trio, though once everyone was ready to go Inko smiled as she lead all of them outside and brought them to the preschool, while Hisashi went to work. This allowed them to look at the world that was around them, seeing all sorts of people walking around, some normal, a few mutants, and a number with clear signs that they had specific Quirks, demonstrating the variety that was available in this world. Like one of them happened to be a guy with a dog head, and possibly more animal parts they couldn't see, while some people had wings, horns, tail, and all sorts of other changes that were linked to their Quirk, which was incredibly interesting to see.

Eventually they reached the building that was their preschool, where Celestia and Selene found a number of other kids that were their age being dropped off by their parents, and one Izuku pointed out to them as they entered the building, a boy with spiky ash blond hair, Katsuki Bakugo as they learned.

Inside the room that they were joining, which was Izuku's and Katsuki's, the sisters found a number of kids that were eager to meet both of them, such as a boy with a wide smile and slightly longer fingers than a normal person, a kid with a buzz cut who had a pair of red wings on his back, and all sorts of other kids. Most of them appeared to be perfectly normal at a quick glance, but it was clear that many of them already had their Quirks, as a few seemed to be talking about their powers and how happy they were that they weren't Quirkless, as if they were already focused on being heroes. It showed the sisters just how ingrained the topic was in society, where kids were influenced to be heroes just by watching and seeing existing ones in action, much like how their brother was fascinated by All Might and hoped to be like his idol at one point. Neither of them knew how good the large fingers Quirk would be for hero work, it seemed kind of lame if Selene was being honest, but for the time being both sisters remained silent as they joined the class, finding that many seemed to be staring at them.

The staff members, their teachers, were a young pair that were likely fresh out of high school, a lady wearing a pale shirt with a pink apron over it, who had brown hair that reached her neck, while the other was a young man that was the same age and had short coal black hair as he wore a blue sweater with a yellow apron over it.

"Class, we have some new arrivals for you to meet: Celestia and Selene Midoriya, Izuku's new sisters." the lady stated, where she gestured to them with one of her hands, causing the pair to walk forward and find that the other kids were definitely far more interested in both of them, especially since Selene was a mutant and she was sure Celestia was getting attention due to her hair color.

"Sure, they might be amazing, but I've got a feeling today's the big day." a voice said, causing the sisters to see that it was just Katsuki, he seemed to be under the impression that he would be manifesting his Quirk today, why neither of them knew and neither of them cared for his reasoning for thinking of such a thing, and there was a smile on his face, "I'm going to get a Quirk that will blow you both out of the water!"

Selene decided that she didn't like him, as he seemed like an arrogant kid who might become worse with time, especially in a world like this, though Celestia didn't seem to mind as she joined Izuku, causing her to mentally sigh as she followed after her siblings and glanced at the other kids. Fortunately it seemed like most of them were used to Katsuki's words, like he was a leader of sorts for the kids when the two adults were busy with something else, a chosen or self-appointed leader she had to guess, but at least it looked like there wasn't much for them to worry about. Selene and Celestia discovered that most of their time would be spent talking and playing with the other children, using toys or gesturing with their limbs, and the pair of teachers had little lessons for them to take part in so they developed the necessary skills to make connections with all sorts of other people while they grew up. It was actually quite nice as Selene discovered, even if it seemed like many liked her due to her pony aspects, but she had to admit that the positive attention was better than what she was expecting, and some of the other students even wanted to brush her tail and hair.

Based on what she was seeing as the morning ticked by both she and Celestia were actually the focus of the other kids, due to the fact that they were new to the class no doubt, but neither seemed to mind, in fact they liked being accepted despite this being their first day in the preschool, before the peace was shattered.

"Oh wow. Is it happening?" one of the other kids, the red winged one who seemed to be one of Katsuki's closest friends, or maybe even more like a minion as Selene thought about how the boy seemed to be acting, stated, which was when Selene, Celestia, and the others turned their heads towards the ash blond boy in question as he held his hands out, causing them to see that sparks seemed to be appearing above his palms, like little explosions.

"Oh yeah! It's totally happening!" Katsuki replied, with what had to be the widest smile he could manage right now, especially when he heard the teachers mention that this was a flashy Quirk and was no doubt suited for hero work, something that put an idea in his mind that Selene was sure was going to shape his entire personality for years to come, all while he held both of his hands out for the others could see his power in action, "My Quirk is awesome!"

"Kacchan, you're so lucky." Izuku said, as this was definitely an amazing Quirk and he was eager to learn more about it in the future, learning about it while his friend did the same thing, and it was easy for him to see that everyone else was eager to see more of Katsuki in the future, before he suddenly felt hot and noticed that many of the others were the same way all of a sudden.

Selene discovered what it was almost instantly, she knew it far better than anyone else, as it seemed like the explosions that had come from Katsuki's palms had, somehow, triggered a sort of awakening in Celestia, because she could feel the familiar presence of the solar magic her sister was known for. That thought was due to the fact that a small orb of sun energy was now resting above her hand, in fact it was like a small marble, to show that her control over her magic was far lower than what she had back in their home world, and yet there was no mistaking the power in her hand. In the next moment Selene found that Celestia's focus was disrupted by something in her mind, though that was when alabaster scales started to grow on her arms and legs, in fact it seemed like her entire body was being affected by whatever was going on. Celestia growled as she fell to her knees for a moment, where Selene, Izuku, and the others watched as her hands and feet turned into claws, a pair of scaly wings grew out of her back, without her attire shredding, as a scaly tail grew out of her spine, and her head took on a new bestial form, her teeth sharpening into points.

This came as a surprise to Selene, that Celestia had unlocked the power to turn into a dragon, one that walked on four legs like what she and her sister had seen back in their home world, something that came as a surprise to Celestia before she passed out and her head touched the floor.

"What... What did we just see? Two different Quirks in a single body?" the man commented, while at the same time the lady seemed to be in the middle of pulling out her phone so she could contact their mother, though he also noted that Selene might have awakened her own Quirk and had yet to realize it, given the vampire-like fangs he was sure weren't there a few moments ago.

As Selene rushed to her sister's side, because she was actually worried about Celestia, she did notice that Katsuki now had a frown on his face, because Celestia had unknowingly upstaged him on a day that he intended to make about himself and this meant they were going to be in his crosshairs for the foreseeable future, though this only made her wonder what this development might mean for them and their new family.
