It's been several months since the start of Class One A's adventure into U.A's hero training course and while it wasn't always as exciting as most would think it would be, there was a certain amount of joy out of knowing that they had gotten this far and stronger with every passing day. It had been a quiet and peaceful Saturday morning, almost everyone coming down to eat breakfast together and chatting about random topics and what they had planned. There were however two people missing this peaceful morning and that was the class explosive manic and their class cinnamon roll which was odd since they were typically one of the first ones up for self training, Uraraka having noticed after everyone had sat down and started eating noticing that the two boys were gone. "Maybe they decided to sleep in?" Tenya said since this week of training had been rather rigorous compared to anything else they had done during the school year. "I don't kn-" Uraraka was cut off by a loud voice coming from a floor above them, it had actually quoted everyone at the table.

"What do you mean he's coming today!? Why is that bastard coming here after everything he did to us!?" It was hard not to hear and so clearly too that and had to wonder what was going on exactly, while they could hear clearly that couldn't make out the voice and wondered if it was Bakugo yelling on the phone or something. "I don't care if he says he's changed and we both know that's just him trying to come back into our lives after things started getting better for us!" It was quiet after that for a few seconds and it was probably someone on the phone because they could only hear one loud voice. "You didn't let him in did you!? Did he touch you!? I swear to fucken god I'll kill him if he touches you!" It was quiet for a whole minute and everyone wanted to know because whoever this person was that did something horrible, they should just run and never look back or think of coming here. "I'm gonna fucken kill him!" Then it was completely silent and everyone waited to see who came down the elevator or stairs. They knew it wasn't Bakugo because it didn't sound like him and only Aizawa was here in case anything happened that warranted his attention, leaving one person who it could possibly be but no one wanted to imagine their most kindest classmate could sound that mad.

When the elevator dinged all eyes watched as both their missing classmates exited it, deeply surprised when they saw Bakugo try and actually talk to Midoriya whose hair was covering his eyes but the deep scowl on his face proved how mad he was. "Listen to me, Deku! If you go there and if he's still there, if you kill him, regardless of if it was in self-defense or not, it'll not only stay on your permanent records but you could also get expelled from U.A!" This was the first time they had seen Bakugo act so worried and slightly scared about anything, so the fact that he was actually trying to stop Izuku from committing murder was not how they thought their morning would have gone. "Lets just tell Aizawa-sensei what happened and have him take care of it! Damn it Deku, listen to me for once!" Izuku stopped and for the first time today they could no longer see the kind hearted and gentle boy they met on the first day of class, no, these were the eyes of someone absolutely furious!

"That bastard left us and took everything from us, leaving us struggling and barely able to keep our apartment. There were days when we had no food in the house and I wondered if it would have been better if I had died, then this would have never happened and that mom would still be living a happy life to the fullest. Seeing her cry every night while working and taking care of me, I swore to become a hero so that she wouldn't have to cry again over some piece of shit like him!" Bakugo and everyone listened and couldn't believe that he had gone through something like that and still come out as kind as he was, even though he had watered it down so that no one would know everything that happened. Bakugo was taking it the hardest because he remembered finding out his father left when he found out Izuku didn't have a quirk and had only bullied him about that, never realizing that it had been that bad and when the greenette didn't have food or required things it was because they had no money.

"Now that man comes back and threatens my mother, going as far as laying his hands on her!" Izuku's eyes were filled with uncontrollable fury, and it seemed no one knew that he could get this mad. Bakugo took a step back in fear for the first time and he realized that even the boy he knew since childhood could get this way, after everything the explosive blonde had done Izuku had forgiven him and he now knows he was lucky for that too. This wasn't the same Izuku that he remembered since childhood, this Izuku was out for blood and promised to do just that. Just then the elevator dinged and out stepped Aizawa dressed in his hero outfit and looking very much the tired man he was, looking around at the silenced classmates and wife eyed Bokugo. "Can someone explain to me what is going on? I first heard shouting and now when I come down everything is quiet." No one spoke because how were they supposed to say that Midoriya Izuku, literally the kindest and good hearted person they had ever known, promised to murder his supposed father after he had apparently threatened and hit his mother.

"Deku… he's gonna kill him." Aizawa's confusion was how much the boy didn't believe what he was saying, and the older man looked towards his class rep to see what was going on. Tenya stood up and opened his mouth only to close, repeating the same process several times before finding the right words. "Midoriya apparently got into a loud call this morning and when he came down, Bakugo looked to be trying to calm him down. Midoriya then explained what happened, that his 'father' had come back threatening his mother and what we assumed hit her too, before walking out the building saying he was gonna kill him." That only seemed to confuse the older man still but realized that something had obviously made one of his students made from what they had said.

Izuku stood outside the apartment door holding back the dam of anger by what little patience he had left and knocked loudly on the door. After a few seconds the door opened revealing the one 'man' the greenette ever hated from the depths of his soul, a smile and ever so joyous that said nothing was wrong. He was of average height with short brown hair and green eyes, fairly slim with a good complexion wearing a two piece business suit that looked to cost more than their place. "Welcome home, son." The exciting tone only served to strengthen his anger but he would deal with the person later, he pushed the man aside roughly and saw his mother in a corner in the Kitchen. "Don't worry about her son, she is of no importance now." Izuku's eyes twitched at his words, seeing his mother in this state again after years of finally getting better! "You don't know how glad I am that you finally have a quirk, even if your body can't handle it yet, but your performance during that sport event thing really showed me your worth!"

Black and green lighting started to surround his body, his mother was murmuring incoherently and shedding tears while this piece of shit man kept speaking about how proud he was. "Why don't you live with me, son? Come to America with me and be the number one hero over there, you could-" but he never finished as he was punched with a sickening crack before hitting the outside wall, the only thing that saved him from falling three high stores and hitting the ground. "You little bastard! I am your father!" All he was met with was a furious Izuku as green and black electricity came off him, his fist at his side tightly as he glared at him with murderous eyes. Flashes of this man hitting his mother and calling her worthless, all the tears and pain screams he could hear as she begged him to stop, all the times they struggled after he took everything… everything came to the forefront and now he would end this nightmare for his mother, so they could move on. The moment he took a step closer Hisashi could feel an overwhelming amount of killer intent and he finally saw that he would die if he didn't escape, fumbling, the man finally got up and started to run only for something to warp around his leg and drag him back. "Help! Someone help me!"

Looking at his leg to see a black thing he followed it up to Izuku arm before another one wrapped itself around his throat, bringing him up to Izuku eyes level and for the first time in his life he wished he had never come back. "Please! Pl-please let me go! I-I promise to nev-never come back again!" Hisashi pleaded as tears fell from his eyes, staring into emerald eyes that showed no mercy in them. Izuku grabbed his arm, before speaking. "This was the arm that had caused my mother so much pain…" before crushing it without any hesitation, the older man screaming in absolute pain in his arm he would no longer be able to use if he lived. He ground the other arm. "This was the one that had caused my mother to scream in pain every night…" before crashing his one and exciting him to let out another howl of pain, tears and snot coming down as he pleaded and begged Izuku to stop all this. "You never let my mother go after she begged and pleaded, didn't you?" He slapped the man across the face, half his face red and in pain. "You continued to beat her for hours into the night and left her in pain, didn't you?" He slapped him two more times, knocking out three teeth and a bit of blood coming out. "You physically and mentally abused her out of having a worthless and disgusting son, taking everything she owned and had before leaving us to almost on the streets… didn't you?" This time he held the man over the ledge and watched as he struggled, the black tendril tightening as he spoke.

"It took years for my mother and I to finally find peace… to get away from the nightmare you left upon us. Now…" Izuku reached forward and grabbed Hisashi's neck with his hand, squeezing hard and watching him squirm and try to release his grip. "…I will end this nightmare…" Izuku released his grip and watched him fall. "Permanently." Hisashi screamed but before he could fall he was grabbed by a yellow blur, passing out from the pain and shock taking over his body. Turning his head to the side he saw his sensei and his mentor, looking at him in complete shock at his appearance and what he had just done. "Aizawa-sensei… All Might…" but before he could say anything else the power that filled him disappeared and he fell to his knees before he was caught by white capture tape, All Might going inside to see Midoriya Inko crying in a corner with wounds. He could finally understand why EraserHead did his best to stay out of the limelight and why he always grumbled while going through papers, because he could already see the enormous stack and the potential media frenzy that can and most likely would come from this. The number one hero pushed that to the back as he focused on treating the two greenette a and getting statements from them once they got better on what happened.

It's been several days since that day and Class One A knew something had happened that Saturday morning since no one had seen Izuku or Aizawa-sensei return, with all the teachers being very quiet and not letting any of them know what was going on with him either. It wasn't until Wednesday night that they saw their homeroom sensei come into the dorms where they all sat in the common room. "Midoriya Izuku has been in the hospital for the past few days due to a massive quirk overload following the Incident that took place." Everyone was shocked since while quirk overload wasn't uncommon, it was many due to extreme situations that forced the user to use more than what they could handle. "While I'm not going to explain everything since that's up to your classmate, just know that anger is a powerful emotion and one that can make people do crazy things that, for right or wrong, have consequences he was barely able to avoid. If anyone has something they need to talk about in the future, know that we as your sensei's are here and so are your friends. Remember that. Midoriya will also be returning tomorrow afternoon." With that the tired pro hero left to finish up paperwork that his problem child of a student has caused for him.

Aizawa didn't know what he did to keep what his student did out of the media but he didn't want to know, just glad a potential hero wasn't going to Tartarus for what he did. Feeling his phone ring, he answered it to hear All Might on the other side. "Young Midoriya finished with telling us everything on what had happened without leaving a single detail out, on what happened and what Hisashi did in the past. Tsukauchi will be bringing you everything in the morning." The underground hero was curious to know what this person had done to have caused his student to risk his future and almost kill his father, he would find out in the morning so at least he didn't have to wonder for long. "Also, Nezu has given permission for you to give him any punishment you deem reasonable as long as it does not interfere with his studies." That put a grin on his face before the two of them hung up, putting his phone in his pocket and stopping in front of the U.A school building. "Why do I always have the problem children?"

The next day their greenette classmate was seen back at the dorms once they had returned from classes, questioning him on what had happened and if he was okay. Izuku had only told them that he had been overtaken by his anger at the man he once called father, taking his anger out on him for what he had done. He smiled glad he had people on his side that wanted to protect him and give him one more chance to fix his mistake, glad he could continue his hero academia with all his friends and free from the nightmare that had been overshadowing his family. He was glad that his only punishment was that he was restricted to the dorms on the weekend for the next three months and he was to sit on the sidelines for the next three weeks during hero training, along with taking out all the trash in the dorm and making sure everything was done before bed. Izuku was given a scolding for Idea and a worried look through by Ochako, and maybe one day he would tell them everything that had happened that day and what had caused it but for now… for now he would enjoy the peaceful days that were sure to come.
