My Hero Academia: Blood and Fire

After learning that Izuku had his own mentor that would be showing him the ropes, and that their brother was all right after what he had been through, since the sisters learned about the whole sludge villain after seeing All Might's attack that had altered the weather a little, things got more exciting. Mirko and Ryukyu did their best to make sure the sisters were ready for whatever tests might be waiting for them, both making sure that they had experiences in dealing with large villains, small ones, rescuing people, and anything else that they could think of. Of course Selene found that her mentor also engaged in all sorts of battles, each one additional training for her to get involved in, especially when they clashed in the forest, where the two of them had smiles on their faces like always. Celestia, as usual, was focused more on helping people when Ryukyu had her lessons, which made sense to her since her mentor had her own area to watch over and had to fly out to see her, but when she did train with Ryukyu she made sure to devote her full focus to her lessons.

A few days after hearing that Toshinori intended on being Izuku's mentor, however, the sisters stopped by the area that their brother would be training in, where they found that it was on one of the beaches, the trashy one that had all sorts of junk on it, and Izuku was pathetically hauling a trashed refrigerator towards a truck.

"Does this really qualify as 'training'?" Selene asked, as it looked like All Might was just using Izuku to clean up a beach and make it a place where people would come hang out again, instead of actually giving their brother a game plan so he could prepare for the entry exam, where she knew her brother would pass the written portion easily, but the physical exam would be harsh for him.

"Yes, it does. Your brother has spirit, but he needs a body that will help him out." Toshinori replied, as he made sure to be in his skinny form whenever the sisters were nearby, because he wasn't sure he trusted them right now, but fortunately it did look like Izuku was being true to his word and had said nothing about his true self to anyone, "I have ten months to mold him into someone whose worthy of becoming a hero, and to do that I have charted out a plan for him to abide by, while also taking into account his current schoolwork. It's the 'Aim to Pass, American Dream' plan!"

"I know Izuku will push himself to surpass your plans, since you're working for All Might and he adores the Number One, but even I have to admit that this is... extreme." Celestia remarked, looking over the slips of paper that Izuku had given her when she and Selene arrived, as it was an accurate time table of the hours that their brother poured into his classes, the hours he spent sleeping and eating, and literally everything else, almost like Toshinori was a stalker of sorts, "He's never done anything like this before, so you're going to run him into the ground in no time... he might not be able to enter the exam if he pushes himself to the breaking point."

"Sounds like you don't have any faith in him." Toshinori remarked, which was understandable since he had found out that the sisters not only had mentors of their own, Selene had Mirko and Celestia had Ryukyu, both impressive in their own ways, both apparently also had two Quirks each, the former had Tiger and Hydra while the latter had Dragon and Sunshine, and it was Celestia's sun based Quirk that interested him the most, but all of this pointed towards the sisters having no faith in their brother's abilities.

"Oh, that's where you're wrong. We have faith in our brother, he'll do anything to make you, and All Might, proud... but he's also one of his greatest fans, and will no doubt go beyond this to prove himself." Selene stated, because she and Celestia had a good idea of what Izuku would do, especially now that he had been chosen by someone who 'worked with All Might', a fact that made her bite her tongue since she wanted to call All Might out and ruin how Izuku viewed him, but she remained silent on that topic, "This plan will give him a decently strong body, enough to handle some of the minor tests that might be offered during the entrance exam, but there's a chance that he'll push himself too much to make the two of you proud. Just pointing that out."

Selene was proven right almost immediately, as when the following day of school arrived Izuku's focus was more on what he needed to do to prove his mentor right, the steps he needed to take to make sure his muscles grew at the desired rate, and how he needed to go about pushing his body to it's absolute limits. He was mumbling more to himself when class wasn't in session, and when it was the sisters made sure his focus was on their teachers and the assignments, even though many of their classmates thought that the sludge villain incident had messed with his mind somewhat. Selene even found that some of the other students thought Izuku was neurotic now, some thought his mind was messed up from the incident, and others just thought it was cool to pick on him now, even though she and Celestia caused everyone to back off so Izuku could focus on his various studies. The only one who didn't seem to be interested in picking on Izuku anymore was Katsuki, like he had seen a part of the boy he had bullied that he hadn't seen before and was respecting it, though she knew it wouldn't be long before he was back to his old ways.

Sure enough not the day following that Katsuki was back to picking on Izuku, which caused the sisters to step in and force him to back off once more, but for the most part it looked like their brother was focused on his normal studies while he was in school, and when they had free him he focused on his heroic training.

Selene and Celestia found that Toshinori was a taskmaster, a harsh mentor to be exact, because when Izuku headed to the junky beach there was always something to do, something to teach him, and something to complain about, almost like he was pushing Izuku towards some great destiny. What they watched Izuku do involved hauling heavy pieces of junk, some of which were too heavy for someone like their brother to move, while his mentor pointed out how he had to put his back into the process, that he had to work out with weights to improve his muscle, and even running laps when he failed to move one of the items. Every moment he was on the beach was basically the same old thing, and Toshinori even revealed that he had a whole multiple phase system designed to help Izuku out, which included doing push-ups in his own time, eating a lot more than he was used to, and even running at night. The problem the sisters had with this was the fact that it was literally ruining their brother, he was exhausting himself and even found ways to cut out the unnecessary sleep hours that he could afford to miss out on, putting even more strain on his body in the process.

After about two weeks of this, and Izuku ignoring both Selene and Celestia's pleas for him to stop, he just wasn't ready for this sort of thing, their brother eventually paused in his training as he hurled up bile onto the ground, causing him to wipe his chin as he huffed for a moment.

"Come on, brother, you need to rest. At the rate your going, you can say forget following Toshinori's stupid plan." Celestia said, as she was worried about her brother, he was literally working himself to the bone with how he was adjusting to each part of the plan and his own personal changes so he could ensure everything he did would benefit him in the end, and right now it seemed like he was going to ruin his body.

"The plan is supposed to make one take stock of their athletic capabilities and alter their approach, though it's too soon for us to see any real results." Toshinori remarked, and he had made sure that it would work for someone like Izuku, despite the fact that the boy didn't have the same amount of time that he had been given before he received One For All, not that he'd tell the girls that information.

"Back off, prick. This isn't training, this is overworking someone to the point of exhaustion." Selene said, as she agreed with her sister, this entire plan was stupid, even if it was designed to make Izuku the newest vessel for One For All, since she had to assume that this was the whole point behind what All Might was doing, "You're hurting him more than you're helping him, let's get that straight..."

"Selene... Celestia... let me do this. I need to work hard, to catch up to the both of you." Izuku stated, because he knew that his sisters were both gifted with powerful Quirks, in fact he had to remind himself that they each had two Quirks, unheard of in the entire world, and since they were blessed with greatness he needed to work hard to catch up to them, especially if he wanted to be as strong as All Might one day, "I can't stumble and fall now, I need to work as hard as I can to ensure that I don't fall behind either of you."

Selene really wanted to smack her brother and tell him that this was a bad idea, All Might didn't really care about him right now, rather she was sure that he saw Izuku as someone to carry on his Quirk and nothing else, and this was one of the times where she hoped she was wrong. This was also one of the times where she wished that Celestia knew about the bar and the fate of their father, because she had a feeling that this would drive her sister up the wall, but since Hisashi didn't want the rest of his kids or Inko to know the truth she had to hold off on the idea. With that in mind she and Celestia had to watch as their brother continued his harsh, if not intense and over the top training, as he was determined to use the ten months that they had to the fullest potential he could muster. He even started bringing a device that helped with his grip strength to his classes, showing them that he was fully dedicated to the training that Toshinori was giving him, but since he was getting good grades their teachers allowed him to do whatever he wanted, even if some students still laughed at him.

By the end of the first month of this, however, Selene eventually caved and sneaked out one night so Kurogiri could open a gate for her to use, where she found that the bratty boy was nowhere to be seen, allowing her to head back into the area her father called home these days.

"Selene, it's good to see you again." Hisashi said, because while he no longer had his actual sight, thanks to All Might, he had found a few Quirks that allowed him to see everything that was around him, so while he couldn't like he used to he did have the ability to 'see' his daughter to some degree, and there were other copied Quirks he had so he could see like a normal person, but he was still learning to use those ones, "What brings you here tonight?"

"I... wanted to tell you what's been going on recently, instead of saying it over the phone: All Might is training Izuku." Selene replied, deciding to just cut to the chase and not beat around the bush, because it was something she wanted to talk about so she could actually vent and not get annoyed with Izuku.

"...What? All Might... is training my son?!" Hisashi replied, as he was shocked by this information, it wasn't something he had even considered in the grand scheme of things, in fact when he suspected that All Might be looking for a replacement, so he could pass on One For All, he expected his foe would have chosen someone else, not his own son, "He's planning on making him into a vessel so Izuku can use One For All, isn't he?"

"That is my thoughts on the matter. Can't confirm it, though, since he's shown his base form, Toshinori Yagi, to both me and Celestia, and he's said nothing about One For All to us." Selene stated, though while she understood the need to keep some secrets, she was doing that right now, she and Celestia had shown him that they were trustworthy and he likely told Izuku to keep his mouth shut on what secrets he knew, "Izuku's probably already seen the wound in All Might's side, but he's made no mention of it to us and our brother hasn't said a word of it... All Might seems to be playing at a Quirkless mentor right now, to prepare Izuku to receive One For All. Considering how powerful the Number One is, I have a feeling that it'll be very painful when our brother goes to use it, even though he's going through some ridiculous training to make his body ready for when it's time to inherit the Quirk."

Hisashi remained silent for a time, as this wasn't in his plans to obtain One For All, he never imagined that All Might would be interested in his son, much less any member of his family, and now he was at a crossroads, because if Izuku really gained the one Quirk he wanted he might not be able to bring himself to rob Izuku of his dreams a second time.

"Selene... I want you to keep an eye on Izuku and his supposed 'training'. See if you can't find anything else out, but I want you to focus on your brother's health." Hisashi said, though he had to keep the anger out of his voice, as this was a massive deviation from his plans and he wasn't sure how to proceed, not without ruining his son's life again, so he needed time to come up with a new plan, though his anger was more focused on All Might being anywhere near his family, "After my battle with All Might, I don't trust him to know how to train anyone, much less my son, so keep an eye on Izuku and make sure he doesn't do anything drastic. Izuku will no doubt want to go with you and Celestia to UA, so I'll arrange for someone else to take the exams and try and get into the class... give me a set of eyes and ears on the inside."

"You... want to send a spy into the school, to keep an eye out Izuku? Why don't you ask me to do it, since I'll already be there with Celestia?" Selene asked, as it seemed weird to risk someone else for Izuku's sake, even though she knew her father would literally move Heaven and Hell to make sure his son had the life that he desired, not the life that Hisashi wanted for him, showing her that her father loved all three of them equally.

"Because in the off chance that someone realizes what's going on, I don't want your future ruined. You want to be a hero, one that saves lives and doesn't focus on the fame or money, and I won't endanger that." Hisashi replied, though while it did pain him to consider the potential for someone else's life to be ruined, even if it was for the sake of his family, he was willing to do everything in his power to make sure Izuku, Selene, and Celestia had the lives they wanted to live, "You can still report to me about your progress, like a child would do so their parents know they're doing all right, but please, leave the shadowy business to me and my friends."

Selene nodded and hugged her father, as she trusted Hisashi, even though he was a villain, due to the fact that everything he had done was for her and her new family, and for a better future for the world when she recalled how he explained his vision in the past. Following that talk Selene returned to her room and faced what the coming weeks had in store for her and her siblings, where she and Celestia continued to dominate the various classes they had, to the point that none of the others could hold a candle to them, even Katsuki fell behind them. It was satisfying to see him fall behind, especially when one of the people he fell behind was Izuku, who was sacrificing the vast majority of his spare time to do his own training, while his sisters made sure he got enough sleep. They didn't want him to collapse from exhaustion, even though he kept pushing, to be the best he could be and keep pace with them, in fact he wanted to be as strong as the strongest hero, an unrealistic dream even for him, but it was his motivation to keep going.

Eventually the ten months passed and Izuku managed to overcome his training, his body was now somewhat toned, not by much, but there was evidence that showed he could push himself to be the hero he wanted to be, something that made the sisters look forward to what the exam had to offer them, and what the future had in store for all three of them.
