Chapter 10

All for One was currently on his way toward Izuku's apartment. About three weeks ago, he had gotten an enchanted letter, which somehow found him, and it was from Izuku. She had written to him telling when she would be returning to Japan. Over the past few months, he had started becoming noticeably uncomfortable, even to Kurogiri, because he was unaware of Izuku's exact location. All for One was always someone who kept a close eye on those who interested him, and since Izuku was completely outside his influence, he felt… vulnerable.

His quirk, for months, has been causing him extreme pain, and while usually, he can handle it, to feel this burning pain daily was proving exceptionally difficult. He had also become more irritable, and the slightest things have been setting him off. It seemed like he was no longer in control of himself, and he didn't know why. Why was his quirk making him feel this when Izuku was gone?

Now standing in front of her apartment door, he knocked three times and waited. Once the door opened, he felt his eyes widen a little and the sight of Izuku. She looked like she hit a massive growth spurt and it has only been a few months. Standing before his was not the same little girl that had saved his life, but a stunning young woman, he didn't know how to feel about this. Her hair reached the middle of her back with a yellow ribbon tying the middle section together. She had a curvy hourglass figure, that was noticeable through her black school uniform.

Deciding to greet his little one. "Hello, little one, I am glad to see that you are back."

"SENSEI!" Izuku had then run up to him and hugged his midsection. Izuku's head reached the bottom part of his chin and her head was currently dug into his chest. All for One was definitely surprised by the sudden affection. Almost instantly, his quirk started to vibrate within him, and his gloved hand immediately found its way behind her back. All for One wasn't sure how long they were hugging for, but he didn't care, he had his little witch back. Once Izuku let go of him, without his permission, his gloved hand slightly tightened its hold on her back, but she didn't notice.

"I'm so glad you could come, I really missed you, especially since I didn't get to say goodbye to you when I left," Izuku said while smiling brightly at him. Sensei hated to be reminded that he didn't get to say goodbye to her, he still had not forgiven Tomura for what he caused.

"As have I little one, and I am deeply sorry for being unable to bid you a proper farewell," Sensei said while forcing his arms to his sides, his quirk did not approve of the action.

"Oh, it's okay. I know you were probably busy with your family or work. It was kinda selfish of me to force you to come and visit." She said while scratching the back of her head. Something deep within All for One did not like what she had said. Does she think I have a family? A father and mother? Kids? A wife? He also did not like how she believed herself to be selfish. If anyone was selfish, it was him, if he had it his way, he would have told her to stay in Japan, under his watchful eye.

All for One found his hand atop her head like when they first met. "Believe me little one, that was a one time mistake, when it comes to you I will always have time." This statement caused Izuku to blush a little, something. All for One found himself strangely enjoying.

"T-thanks, um… would you like to come in? I have two friends over that I am sure you would love to meet." Izuku said while grabbing his large hand, giving it a light tug.

Sensei's hand tightened around hers. "Well, I do not see why not. Please lead the way little one." Little did he know who was waiting inside.

Izuku smiled and pulled him inside and through the hall. As they were getting closer to the living room, All for One couldn't help but feel a sense of uncertainty. The closer they came to the living room, he could hear two men speaking, both sounding very… familiar.

Izuku deciding to announce them. "Hiko-san, Nezu-kin. I would like to introduce you to Sensei."

Once entering the living room time ceased to function for all of them, once both men turned their heads to Izuku and the man.

Silence

Many things had happened within a matter of seconds. Almost instantly, Izuku found herself being grabbed by Sensei and thrown behind him. From the other end, Gran Torino and Nezu acted with lightning speed, especially Gran Torino.

"YOU!?" Gran Torino yelled and immediately used his quirk while rushing towards All for One. "GET AWAY FROM HER!" All for One having taken his few milliseconds to get Izuku out of harm's way, found himself being thrown across the room once the older man's foot hit him in the face, breaking his nose in the process. He had been slammed into the dining room table, completely destroying it. Nezu had rushed over to Izuku.

Izuku now realizing what had just happened. "HIKO-SAN!? What are you doing!?" She yelled at the older man who was jumping around the room. All for One had already gotten up and transformed his arm into a large sharp blade.

"GET HER OUT OF HERE NEZU!" Torino yelled while rushing towards All for One again. All for One took that brief second to deliver the same treatment he had received from the man, sending Gran Torino flying into the wall.

"SENSEI!?" Izuku yelled, not understanding what was happening. Since when did Sensei have such a dangerous quirk? Why were they fighting? WHAT WAS GOING ON!?

Nezu was trying to force Izuku away from her home, but because of his size was unable to do much in terms of moving the girl.

"HOW DARE YOU COME HERE!" Gran Torino yelled while rushing towards All for One who was doing the same. All for One had his blade pointed towards Torino with the intent to draw blood and Torino with the same intention. What happened next was extremely unexpected.

"IMMOBULUS!" Both men who had been charging at each other threw mid-air found themselves frozen and unable to move. Just stare at each other with wrath and confusion. From both their peripherals they could see Izuku standing there with her white wand in hand, and Nezu just watching. Izuku was breathing heavy and trying to catch her breath and comprehend all that had just happened.

"WHAT! Is going on!?" Izuku yelled while looking between all three men, with both fear and anger.

"Miss Midoriya, do you know him!?" Nezu asked quickly while pointing at the still frozen man, with a large blade for an arm.

"YES! That is Sensei I have known him for a while! Why are you guys attacking him?!" Izuku had then turned to Sensei. "And why are you attacking Hiko-san?!" Izuku knew neither of the men could respond until she lifted the spell, but they could still hear and see everything. Sorahiko was trying to understand what was happening. Why was he frozen? What does Izuku mean she knows All for One? Question after question formed in his head, while he was forced to stare at the man who killed his best friend.

As for All for One, he was asking similar questions. Izuku knows these two bastards? Why can't I move? Did Izuku do this?

"Okay I do not know what is going on, but so help me if any of you start attacking each other again I will transform everyone here into teacups and stick you all in the dishwasher!" Izuku yelled at all three of them while gripping her wand.

'What the hell is the kid talking about? I thought she was quirkless?' Sorahiko thought to himself, still suffering from mass confusion.

"Izuku he is dangerous we ne-" Nezu began, completely forgetting the Miss.

"Stop right now Nezu-Kun," Izuku said with a glare silencing the man. "Here is what is going to happen. One, Nezu, you are going to go sit on the couch and wait." Nezu wanted to respond but found the end of Izuku's wand in front of his face. Without another word, Nezu went over to the couch quietly. Izuku then turned and stood in between both of the frozen men. "Two I am going to unfreeze you two, and you are both going to STOP fighting. And so help me if either one of you even thinks of attacking each other I will stand by my promise on the teacups!" She said while looking between the two men.

All for one did not know Izuku was capable of freezing two powerful men so quickly. If he wanted to get out of this, he would have to listen to her demands. Could she really turn them into teacups? If she could freeze them both instantly in mid-air, it was possible. In truth, he did not know how powerful magic was.

Gran Torino's brain was going into overdrive, trying to comprehend what was happening. It was then Izuku knew that Hiko-san was probably still confused and needed an explanation.

Izuku internally groaned before turning to Sorahiko. "Hiko-san I am guessing you are probably still confused, so seeing as how I've already done it, you deserve to know like both of them. I will explain it to you, but you will have to wait."

'Know what!?' Sorahiko, though.

Izuku waved her wand into the air and started to repair the room to its original state. The table in the dining room began to reassemble, wooden chunks flying and reattaching themselves. Sorahiko, while still frozen, could only look on in wonder and confusion.

"Now, when I unfreeze you both. We are all going to sit down and talk this out, okay?" She said now calming down a bit. There was a slight movement in both of their eyes, giving her a confirmation. "Okay" Izuku then walked in front of Sorahiko and pushed him back, so he and Sensei do not collide when she unfreezes them. With a wave of her wand, both men were unfrozen, and each crashed into something. Sorahiko crashed into the wall, while Sensei collided with the floor. Both men quickly picked themselves up and stared at each other with anger and confusion at what had happened.

"Sit," Izuku said while nodding her head to the living room.

Both men were slow to respond, but eventually, both moved to sit down watching each other with hawk-like eyes.

Now that everyone was sitting down Izuku took a seat next to Sensei, which caused both men on the opposite end to jolt a bit, fear evident in their eyes.

"Now can someone please tell me what is going on?" Izuku asked while looking between the three of them. The tension in the room was through the roof.

Finally, Nezu was the first one to speak, but he was still staring at All for One. "Miss Midoriya, this is All for One a notorious criminal." It took everything All for One had to not slit the little mouse's throat open for telling his little one about who he was, and his name.

Izuku was confused by Nezu's statement. "Criminal? Nezu-kun… I've know Sensei for quite a while, and he has never done anything illegal."

Before Izuku could continue any further, Sorahiko spoke up. "Kid, this guy is a goddam murderer!" Anger seeping through his eyes.

"Okay, enough!" Izuku said, she then turned to Sensei, who was clearly irritated. Izuku noticed that his nose was broken and bleeding pretty badly. "I am going to leave the room and grab some supplies for your guy's injuries and when I come back you three better not be fighting." She said while standing up and walking towards her room to grab some healing supplies.

As soon as Izuku left the room, all three of the men went back to glaring at each other. Sorahiko finally decides to speak, but it came out as more of a low growl. "How the hell do you know her? What do you want with the kid?"

All for one who had been quite finally decided to speak. "I met miss Midoriya a few months ago. She saved my life, and I do not seek anything from her." Nezu and Gran Torino both looked in at the man in shock. She had known him for a few months?

Gran Torino was not satisfied with that answer. "Bullshit! You only care about something so long as you get something out of it. I bet if she knew what a true monster you are, she would have left you to die." All for One felt his rage starting to rise.

"If you are unsatisfied with the truth then might I suggest you refrain from asking the question. Besides, we both know I am not one to lie. I would have thought over the years you would come to that realization." As much as Gran Torino despised the man before him, he was right about one thing, he is not one to lie.

Izuku finally walked back into the room with a bottle in her hand, the label of the bottle read 'Essence of Dittany.' She then sat down next to Sensei and turn his head towards her while she opened the bottle. Nezu and Gran Torino looked at Izuku, in hysteria because she was touching All for One's face, and he was not attacking her, or using her as a hostage. "This might sting a little." Izuku lightly pushed his nose back into place while letting a few drops touch the wound on this nose. Immediately the skin on his broken nose started to reattach, making it look like it had never been injured. All for One couldn't help but relish in the fact that his little one was touching his face, her hands were very soft and warm against his cheek and nose. After healing Sensei, Izuku stood up and walked over to Sorahiko and started working on his wounds, which creeped him out.

Once both men were healed, Izuku went to sit back down next to Sensei. There was an awkward silence coursing through the room.

Izuku decides to break the silence. "Hiko-san, in regards to your statement about Sensei being a… murderer." All for One was staring intently at Izuku, almost terrified of what she was going to say. "I don't care."

All three of them looked at Izuku, astounded at what she had said. How could she not care that the guy next to her killed people?

Izuku could tell all of them were confused. "It isn't my place to judge him if he did… murder people… I believe he didn't do it just for fun. Yes, I know murder is terrible, but you definitely shouldn't be one to judge Hiko-san." Sorahiko looked at Izuku still bewildered. "As someone who loves learning about heroes, I also know that many pro-heroes have been forced to kill villains, so it is not fair to point fingers at someone else. I've known Sensei for quite a while now, and I can tell you personally that he is not a monster. If he did not want to tell me about is past, that is his choice." All for One continued to look at Izuku in shock. The response he heard from Izuku was not what he had been expecting, he would have thought she'd shun him, or lost all trust in him. Even after being told how he had murdered people, she didn't hold judgment over him. His little one also respected how he wanted to keep his past a secret.

Izuku started speaking again. "I don't know what history you two have together, but seeing as how you both wanted to kill each other in my living room, I can say it is not a pleasant one." Sorahiko gave a slight nod. "Well, I do not care what past you two have together, but whatever it is, it ends now."

Sorahiko and All for One looked at Izuku like she was slightly insane. Sorahiko decides to speak. "You expect me to forgive this murderer! He killed my best friend!" Izuku sighed after hearing Sorahiko's response.

'So that is why he was angry, it makes sense.' Izuku though.

"I'm… sorry." All eyes were now on All for One, who was avoiding eye contact. Sorahiko looked shocked at what he had heard from the villain. All for One cleared his throat before speaking. "I admit that I took someone important from you; however, it was not my intention to kill her." Sorahiko just glared at him, not believing him. Izuku was looking between the two men, she was not sure what had happened, but she was not about to intervene. "After you and her… successor escaped, my quirk exploded when she came to close to me, and I told her to get away. I do not find reason in taking life from someone who is quirkless, or unless it is the last option." All for One hated to talk about this in front of Izuku, but it needs to happen lest this situation gets worse. It was also during their battle all those years ago, Nana completed the transfer of One for All to her successor.

"Y-your lying!" Sorahiko was in denial. He wanted to believe the man before him killed his best friend on purpose, it was easier to believe, it gave him a reason to despise the man even more. He lost his best friend, someone had to be at fault.

Nezu, who had been quite this entire time, was analyzing the situation. He could tell that All for One was not lying, he was an expert at telling when someone is not truthful. Nezu raised his voice. "You said Miss Midoriya saved you?"

Izuku decides to answer this question. "Yes, I was on my way home from the Japanese Ministry when I found him bleeding to death in the alleyway. I then used magic to heal him… but I sort of got in trouble for it."

Sorahiko glanced at Izuku. "Magic?"

Izuku turned her head towards Sorahiko. "Yes, magic. I'm talking fly, spellcasting, potion brewing magic. I am a witch, and so is my mom. Technically I am not supposed to tell any of you about magic, the punishment would be me going to prison and all of you having your memories erased." The short man just looked bewildered, he then looked at the other two men who just gave head nods. "In fact, I am probably in trouble right now, I cast a spell on you guys to stop fighting. If the Ministry of Magic decides to check this, then we are all going to be in trouble."

Nezu was confused by Izuku's statement. "I'm sorry, Miss Midoriya, but how would you be in trouble? I remember when we first met you cast a spell on me."

Izuku scooted a little further into the couch, now avoiding eye contact like Sensei. "There is a spell called the Trace, until I turn 17, any magic I use will be documented at the Ministry of Magic. They can tell what spell I cast, when I cast it, even those who were around me at the time. If they decide to investigate further, then they will know about the three of you and wipe each of your memories of me. And the only reason I was able to cast that spell on you Nezu-kun was that we were so close to the Ministry." All of the men looked a little perplexed at what Izuku said, none of them wanted to forget Izuku.

Sorahiko having calmed down spoke up. "So basically what your saying kid, is that because me and him," Sorahiko pointed his thumb over to All for One. "high chances are we are all going to forget you." Izuku just nodded her head slightly.

All for One felt sick upon hearing this. The idea that he would have his very fond memories of Izuku taken away from him. He would forget meeting the little one who saved his life knowing she would get in trouble, the little one who a few minutes ago stood up for him against two pro-heroes. No, this would not happen, he refused to let something like this happen.

Izuku then decides to bring herself back to their initial conversation. However, she had now turned back into her normal intimidated-self, that bravery from before now gone. "U-um now I know this is a lot to process for all of us on both ends," Izuku said, referring to the situation between Sorahiko and Sensei, and Izuku exposing magic. "But can you both just agree to end this? I get that you are mad Hiko-san, but killing Sensei won't bring your friend back, I mean he did say he didn't mean to kill her, and Sensei is not one to lie."

Sorahiko felt sick and confused. He despised the man before him, but it was clear that the kid would never allow them to fight. It was evident to him that Izuku cared for the monster next to her. The kid was right, however, killing him wouldn't bring his friend back, and even if he did kill All for One, it would hurt Izuku. Damn it! Sorahiko gripped his pants, and there was a bit of shaking in his breath. "Let me make it clear, you bastard. I don't like you. I think you should rot in the deepest part of hell for the things you've done but," he took a quick glance at Izuku. "If not killing you makes the kid happy then fine. But so help me if I find out you hurt her I will personally rip your damn head off!"

All for One let a smile escape from the corner of his mouth. "Believe me, I wouldn't dream of it. In fact, if I were to do something like that, I grant you my permission to rip my head off."

Nezu was looking between three of them dissolving what had just happened. It seems that Miss Midoriya was able to put a stopper in this eternal battle between the two men, in a single night. Now there was the question, what happens next? Technically he should notify law enforcement, but this could be the only chance to put an end to more bloodshed between the two men.

After the four of them talked about what would happen next, they all came to an agreement, Sorahiko was against it but still agreed. Once a week the four of them would meet, no law enforcement, and no telling anyone outside of Izuku's house what had happened. Eventually, Nezu and Sorahiko left, though Sorahiko was forced out because Izuku said she wanted to talk to Sensei alone. Sorahiko made her promise to call him immediately if something happened and he would be there in seconds to rip All for One's head off. She gave him a pat on the head and told him there was nothing to worry about.

Eventually, Izuku and Sensei were the only ones in her apartment, and there was a strange silence between the two. All for One hated it, his little one now knew a part of his past that he had wanted to keep secret. The more he thought about it, the more his quirk started to burn him.

Izuku could tell that Sensei was ashamed because she knew about part of his past. She decides to sit down next to him and patted his ungloved hand. "I don't see you any different."

All for one who was suffering in his own world looked at Izuku shocked at what she had said. "I don't know everything about you or the people you have… murdered. But from the time that I've known you, I can say you aren't a monster. If you were, you would have killed me after I healed you, or tried to indoctrinate me like some villains out there. Yet, you've been very kind to me, so thank you." All for One was still in shock by the end of Izuku's speech. After hearing this, his quirk decided to control his body, instantly Izuku found herself being hugged by Sensei. She couldn't help but blush at the sudden hug. She was so small compared to his massive body, his entire hand could wrap around her neck he wanted to. Izuku decided to return the hug and wrapped her arms around his midsection, during this hug, she failed to notice the black electricity wrapping around them.

All for One felt his quirk losing all control. It needs the girl close to him, like how a plant needs water. In all the years he had been alive nobody, not Kurogiri, Tomuru, even his own brother had defended him. Not like this little one did. Before, he believed he owed her for saving his life, but it was clear he was forever in this little one's debt. In a single night, she managed to put an end to a long few between him and Gran Torino, talk about making miracles happen. The longer he hugged his little one, the more he started to feel that intense and pleasant burning sensation in his chest, it was strange because he had never felt this before. All for One notice that during their hug, black electricity from his quirk started to form around them, but he was too invested into their embrace to care. He just decided to hug her tighter to himself, making sure her little form was buried into his chest. This innocent girl was his, and he'd be damned if anyone tried to take her from him.

Izuku could hear Sensei's heartbeat and pressed her ear close to his chest to hear. It had a fast and soothing beat to it. Eventually, the black electricity was launching itself at Izuku, but she didn't feel anything as the bolts kept hitting her body. Once Izuku came back to reality and realized how long she was hugging him for, and her cheeks turned crimson red. Eventually, Sensei let go of Izuku, but in truth, he wanted to keep holding her and continue feeling that indescribable warmth in his chest.

Izuku was a blushing mess, something. All for One was beginning to crave to see more of. "Um, t-thanks."

"I believe I should be the one saying that little one." Instantly All for One's hand was atop her head like it had been in the past. "I should be leaving now, no doubt Gran Torino is waiting outside your home wondering what is taking me so long to leave."

"Ya, you are probably right. Just promise me you guys won't fight anymore? I don't like my friends fighting." Izuku asked while tapping the tips of her fingers together.

All for One smiled. "Of course little one, you have my word." With that All for One found himself leaving. It was when he got to the base floor of Izuku's apartment complex did he notice Gran Torino clearly waiting for him.

All for One groaned internally. 'This is going to be a very long night.'

Author Note
So that is it for this chapter. I really wanted to take my time with this chapter, and I feel like it turned out pretty good. I wonder what Gran Torino is going to do?

Review Response:

Koritsia: Hey thanks again for the heads up on Kurogiri I'm glad you caught that otherwise, I would have been continuing to miss spell it. Just so everyone knows I've gone back to past chapters and fixed that glaring mistake.

Chocoholic202: Sorry! I love cliffhangers, but I felt this needed to be an entire chapter on its own. I hope you enjoyed it and thanks for the review.

VTXD: Yep Sorahiko definitely remembers All for One. I don't think Sorahiko will ever forgive him, but for Izuku. I think at the very least he won't kill him, harming him his a little different.

Healslut: Yes, they certainly do remember each other. = )

FK306: No, the defenses at Hogwarts are actually the same as they are in the movies and books. The castle is hidden behind basically a giant bubble which prevents people from finding it. There was also a scene in order of the Phoenix where a death eater hits the shield and explodes.

Gemava: Oh, believe me, there will be plenty of jealousy in this story. Also, I like Toshinori both in his skinny form and muscular form. He is two sides of the same coin, you can't have one without the other.
