Himiko was at first about to be sent to an orphanage since non of her relatives could be contacted. Inko knew however that Himiko will definitely not be adopted or treated properly because of her quirk so she decided to...pull a few strings here and there and had Himiko be declared a ward of the state.
Simply put, Himiko was now the responsibility of the court, and all her expenses and accommodations were as well. Izuku also found out that his mom was known as Inko 'Demon' Midoriya when she worked as a lawyer and there were still a few clients that owed her 'favors'. Izuku didn't really understand what it meant but as long as Himiko was okay he was fine. Himiko's case was now also handled by Inko so she as able to arrange everything properly for Himiko.
Himiko now literally lived in the apartment in front of their own. It had been empty for a while now so Inko took the opportunity to contact the owner and 'convinced' him to rent the place out. Himiko was also able to transferred to the same school as Izuku so that was a plus too. At least that is what Inko, who was oblivious to Katsuki's real behavior with her son though.
Himiko was ecstatic anyways since she would be able to stay with 'Izukkun' even longer now. Izuku himself was really worried since Katsuki was hell-bent on bringing the 'villain' to justice. Izuku realized that while he may not be able to do much about Katsuki in Middle school he absolutely won't let Katsuki anywhere in highschool. To ensure that this happens Izuku started to record anytime Katsuki bullies him or someone else as well as all incidents of the boy's use of quirk against others, which mainly ended up being himself.
Himiko was pissed at Izuku the entire time because of that, not the planning to make sure Katsuki does not get in school part, it wasn't something she knew and he would like to keep it that way. She didn't like how Izuku hadn't mopped the floor with the blond already but Izuku always brushed her off some way or another.
Izuku had also hidden that he had gotten his quirk for a while now and he planned to do so until he gets to U.A. He did train whenever he could, both his quirk as well as his physical prowess. Himiko was not slacking of either, she took up a martial arts class along with Izuku which they attended every other day as well as weight training. This, they did in the form of clearing the trash from Dogbah beach. The place used to be really beautiful at some point in time but now apparently people took the liberty of disposing their trash here.
At first picking up trash was difficult for both of them due to their skinny physiques but Izuku came through by planning a workout routine fir both of them. It had their respective diets, exercise routines, sleeping times and other activities they should be focusing on. Himiko had a few suggestions of her own as well. She wanted to take dance classes with Izuku in an effort to 'increase their reaction time', Izuku was very very nervous about it but Himiko dragged him along anyways. They took up break-dancing much to Himiko's chagrin. She wanted to take slow dancing or something to have a more 'romantic time' with Izuku but had to give in. After all who could say no to that face full of enthusiasm and those puppy dog eyes? She really needed to up her immunity towards the cinnamon roll's charms.
They had both grown up now. Izuku was now taller than Katsuki if only slightly and a very well built for someone his age. His muscles while lean were hardened and one look at them would let you know that doubting the strength in them would not bode well. While the physical bullying had ceased as Izuku bulked up Katsuki was still as poisonous as a snake when it came to his words. As soon as he heard Izuku was still applying to U.A hero course he banged the greenette's desk with an explosion and went on a narcissistic speech about wanting to be only one in school to enter U.A. He got even more pissed as the teacher announced about Himiko's application to U.A.
"What? This villainous bitch wants to be a hero? Don't make me laugh! Someone like you should just jump off the roof and rid the world of your monstrous existence. You-"
It was at this moment that someone, well...Izuku got off his seat and gave Katsuki's face a devastating punch that sent him flying towards the teacher's desk.
"You really shouldn't have said that." Izuku mumbled softly and then faced his teacher.
"I know that you enjoy whenever Katsuki attacks me or her. Tone down your scumbag of the Earth attitude or I might really do something I regret."
Izuku sat down while the whole class looked at him stunned.
Katsuki slowly got up and growled angrily towards Izuku, "Dekuu!"
"That's enough! Bakugou sit down! Midoriya you come with me to the principal's office.
Izuku simply got up and followed the teacher. Himiko was about to protest but was motioned by Izuku to calm down. He winked at her, letting her know that he had a plan.
*At the principal's office*
Izuku your actions today towards a fellow student and misbehavior towards your teacher will enter your permanent records, your mother will also be informed of your actions.
Izuku simply smirked at the principal and the looked towards his teacher, "You are really sure about making me take all the blame?"
"I am simply reporting the truth." His teacher replied stoically.
"You know, people love the truth, particularly the ,media. Izuku takes out a pen from his breast pocked and takes the cap off of it to reveal a pen-drive. I have the recording of today's 'incident' here. They would love to know what really happens in this school would't they? The past few days have been quite slow after all."
"Midoriya-kun no need to be so impulsive! We can talk this out!"
"Whats the matter senseis, don't you two love the truth?"
"Okay Okay! We will let this incident go with just a simple warning so just, put that under wraps okay?"
"Fine, but remember you better not let the Pomeranian run rampant or i will be forced to look for 'help'. " Izuku smiled voraciously as he left the office.
The last few months of Middle School a lot more peaceful now that the teachers tried their best to keep Bakugou in check. He still tried to follow Izuku and Himik around to 'challenge' Izuku and show him who is better. Izuku of course just played the same game with him along with Himiko as the one when they were still kids.
Days pass by and so do weeks.
It was time for the U.A entrance exams now, as well as the time to send his little 'project' to U.A
