My Hero Academia: Blood and Fire

Selene found that she and Celestia definitely had some busy days after they both encountered one of the other heroes that were in Japan, even though both of them hadn't intended for such a thing to happen in the first place, as she went off when Mirko called her and Ryukyu came by every now and then for Celestia. She had to admit that when Celestia told them that she had been offered some training by the dragoon hero, just like she had been offered some by the rabbit hero, she hadn't been surprised at all, as Ryukyu recognized potential and her sister was full of it. Her sister's Dragon Quirk was one of the more versatile transformation Quirks out there, she was one of the few that could do partial transformations or even make a hybrid form, and Selene's own Tiger Quirk was the same. That also wasn't counting the fact that they were both wielders of two Quirks, the only two in the existence of the world as far as most people knew, since Selene knew All For One was one of the more unknown figures, which would make them more desirable in the future.

Her first fight against Mirko had been in the forest, giving the battle bunny a lot of room to work with while also allowing her to use the full power of her Tiger Quirk to counter her foe's Rabbit Quirk, and at the same time figuring out when to use the defensive power of Hydra.

Selene had to admit that it was interesting, fighting the power of Mirko while making sure not to hurt her or damage the area they were in, the heroine was making sure she knew how to take in the surrounding area into whatever fights she might get in, use everything to her advantage to bring down her enemies. She also discovered that her mentor, for that was what Mirko was to her like how Ryukyu was one to Celestia, was tough and always spoke her mind, pointing out ways for her to improve, despite Selene having been part of Luna for a time, the warrior sister between her and Celestia. Since she couldn't speak about that she just decided to go with the flow and found that there were moments where her mentor was right, to which she made sure to alter her movements and stances, allowing her to offer more of a fight for Mirko. The one thing she made sure to avoid was telling Mirko about Celestia's Sunshine Quirk, as the last thing she needed was for her mentor to know about what had to be the greatest and most powerful Quirk in the entire world.

She had seen enough from her mentor to know that letting her clash with Celestia's Dragon Quirk was fine, but Sunshine was out of the question, and Selene made sure to say nothing about her sister's Ultimate Move, as Mirko would run off and face Celestia at noon, just to experience her power for herself.

In addition to that Celestia focused on her own lessons and caught up with Ryukyu whenever she was in town, because the dragoon hero's office was in another part of Japan, while focusing on her schooling and personal life when there was time to relax, just like Mirko did from time to time. There were weeks where they went without seeing their mentors, which neither of them were surprised by since they were busy heroes that were focusing on protecting the people from villains, so they did their best to help Izuku out more during their spare time. Both sisters continued to maintain their dominance in school, in grades to be exact, and when they made it to the time that sports were introduced Izuku wasn't even remotely surprised to see that they continued to excel, setting high scores while annoying Katsuki. Selene was fine with that, since Katsuki couldn't do anything to them since attacking with his Quirk, without a license, was against the law, even though they knew that such a thing wouldn't stop him since he seemed to believe that the world revolved around him.

While they did that Selene also made sure to check in with their father every now and then, making sure his body was fine as he adjusted to a life without his eyes, ears, nose, and hair, and having to live with all of the tubes that made sure his body could continue to survive, his helm fully modified as a life support item when he had to leave the hideout. Shiro, despite her ties to the new villain group that Hisashi was the Sensei of, since he had a bratty young man who was older than Selene and her siblings, continued to be a shining star, doing her best to save people like a true hero. The bratty young man she stayed away from, he just rubbed her the wrong way if she was honest with herself, and made sure her focus was on her father, and when it was time to go she had Kurogiri warp her back to the alley she was using for him to put the gate in. Selene found that her visits were well received by her father, as Hisashi looked forward to her coming by and telling him about what she and her siblings might be up to, something he confirmed from Inko's calls.

As the weeks turned into months, and those months turned into years at long last, Selene, Celestia, and Izuku continued to grow, where Selene found that both she and Celestia were definitely attractive for teenagers, not that she was surprised by this since Celestia and Luna had been pretty in their alicorn forms. Both of them, from what she could tell, were about the same height that Katsuki was, which was five feet five inches right now, at age twelve, and Selene suspected that Katsuki would be about five feet eight inches by the time he reached fourteen, and the sisters would be the same. At the same time both of them were maturing into fine young teenagers, as Selene found that they were definitely blessed by the magic that sent them to this world, as their chests were developing as well, where she was sure they'd be in either the high B Cup range or even somewhere in the C Cup, but it was too early to tell for sure. Izuku, on the other hand, remained shorter than them and was quite skinny, due to the fact that he never trained his body and only focused on his studies, but he wasn't unhealthy either, as Inko, despite her own weight gain, made sure everyone had enough to eat.

For Selene it was sad, how her mother's worry and sadness over being unable to give Izuku a Quirk had damaged her, and at the same time she knew this wasn't what Hisashi wanted, he never wanted to inflict this sort of pain on his family, as now all four of them were sad whenever they talked about him.

That made Selene think about her studies of All Might over the years, since that fateful day where he stole their father from them, as he seemed to heal just fine and was back to hero duty within no time, but it soon became apparent to her that he had a limit on how much he could do before his body collapsed. In the beginning All Might seemed to be able to do about eight hours of hero activities, which he carefully spread out throughout the day, allowing her and Shiro, as they were both interested in the Number One Hero for their own reasons, to discover something interesting. During his 'down time' there was a new figure in town that was similar to All Might, he was a sickly skinny person with the same colored hair that the hero had, in fact the bangs that were on either side of his face could have passed for All Might's pointed bangs that reached for the sky. It was practically his signature, causing her to wonder why someone who didn't seem to be a fan would style his hair like that, and soon it became clear to Selene when she saw him disappear into a building and All Might jumped out of it in his hero gear, something that caused her to grin.

All Might was crippled, just like the good doctor had said, and he had taken to using a 'powered down' form to conserve his strength, allowing him to stretch out how much time he had available each day, and she suspected that if he reached the limit he'd be forced back into his skinny form.

Another thing became apparent to her as the years went by, some days All Might would just disappear and the villains would either hide or cause problems for the other heroes, allowing everyone else to finally gain some renown, focus, or whatever it was that they were focused on. Selene discovered that it was more surgeries, as the good doctor heard about them despite the effort that the government put into keeping All Might's condition under wraps, and only he, Hisashi, and Selene knew this fact, mostly because Hisashi knew that his daughter took great pleasure in knowing how bad All Might was doing, even if he survived his various surgeries. The good doctor had been right, All Might's stomach had been scooped out completely, as a device had been inserted to keep that part of his body flowing naturally despite the lack of the stomach's main ability, and his respiratory system was in shambles, as All Might's skinny form had a habit of coughing up blood every now and then, a fact that was true based on he strained himself. This also came with a delicious side effect of him slowly losing the amount of time he could stay in his hero form, as it seemed like the more he used his power, the more incredible power that wiped out her father and could alter the sky at times, the less time he had to use for his hero work.

This was due to the fact that All Might started with eight hours after the fateful battle, a year after it he was down to seven hours, two years left him with six, and when Selene and her siblings were twelve she noted that All Might was down to five total hours per day, to the point that she suspected he'd be down to three hours when they turned fourteen.

"He's definitely weakening... he'll likely be looking for someone to pass his Quirk onto in the near future." Selene said, as she was in her father's new room, one set up so he could easily communicate with Kurogiri without actually showing the bratty boy, who had a thing for hands for some reason since he had them all over his arms and one on his face, his body, as he was in the hidden part of the hideout that not even the brat knew about, "Not sure who he's going to pick, but you might be able to get his Quirk once it's passed on to someone else."

"That would be wonderful." Hisashi replied, as he was glad that All Might was suffering as well, that his body was failing him and that soon he'd be limited to a small amount of hero work per day, and it put a slight smile on his face, while at the same time he was able to hear and 'see' Selene thanks to the good doctor's work and a few Quirks he had obtained to make him able to see what was around him, "Tell me, are you still planning on attending UA when the time comes?"

"Yeah, Celestia and I are definitely heading there. They would be fools not to accept us, since we both have two Quirks each, and that's not counting that we have some training already." Selene answered, because she knew her father wanted them to follow their dreams, and right now she was focused on making society better for everyone, regardless if they were mutants like her, normal citizens, or people who were called villains for not fitting into the mold society wanted them to be a part of, so she didn't have to worry about him asking her to be a spy or anything, "Just a few more years of middle school and then we'll take the entrance exam, and then we'll tackle whatever challenges and obstacles UA has to offer us."

Hisashi smiled as he told Selene that he knew she and Celestia would do wonderfully, and that Izuku would do well in his own chosen path, because he trusted his children and wanted them to be happy with whatever they did, which made him all the more eager to hear what the future threw at them and how they would handle the challenges the coming years would offer to all three of them.
