Once school had started again, everyone was talking about their internships. Bakugou was talking about how Best Jeanist was quite impressed at his attitude, Uraraka was giving off an aura of confidence, and Shinso seemed more rested. His bags were lighter, and he seemed to carry himself better. However, Iida, Shoto, and Izuku were just hanging out in the back. "So, I heard that you guys took on the Hero Killer! I'm really glad you're alright!" Kirishima said, giving a thumbs up. "Well they were saved by Endeavor, so that's fortunate," Sato replied. "Yeah, but the fact that there was no body left, not even ashes, is incredible! The temperature required for that is over seventy-four thousand degrees celsius!" Momo exclaimed. Bakugou scoffed. "The story's bullshit," he replied. Everyone turned towards him. "What do you mean?" Sato asked. "If the temperature was that hot, it would've killed everyone there, and utterly fucked up the area. No, I don't think that's what happened," he replied. "But… what else could utterly destroy a body?" Todoroki asked, desperately trying to stay with the story.
Bakugou laughed out loud. "So it was a fucking cover-up! I knew it!" he declared, smacking his fist into his palm. "Huh?" Kaminari asked. "So, does anyone know what, or should I say, who, could utterly erase a body like that?" he asked. "I couldn't! Who do… you… oh." Mina replied, trailing off, and looking at Izuku. "Kacchan!" Izuku whined. "You… consumed… Stain!? You killed willingly!? That's so unmanly!" Kirishima exclaimed. "It wasn't willingly," Todoroki explained. "What do you mean?" Fumikage asked. "Midoriya was carried off by a winged monster. Stain leapt into the air to kill it, but then Endeavor sent fire at all three of them." Everyone gasped. "When the smoke cleared, the monster was dead. Izuku was on death's door. Stain, however, was fine. He grabbed one of the tendrils and impaled himself. So no, Izuku didn't intentionally kill him. Stain killed himself," the bichromatic teen explained. "Oh… I'm so sorry, Izuku… I didn't realize…" Kirishima responded.
It was later in the afternoon, and they were all doing their Hero training at one of the school training grounds. "I AM HERE!" All Might shouted. "IT FEELS LIKE IT HAS BEEN A WHILE SINCE I LAST SAW ALL OF YOU! I HOPE YOU ALL DID WELL AT YOUR INTERNSHIPS! TODAY WE WILL BE DOING A RESCUE RACE!" Shinso raised his hand. "YES, YOUNG SHINSO?" All Might asked. "Sir, shouldn't we be doing this at USJ?" he inquired.
"WELL YOUNG MAN, THAT FACILITY SPECIALIZES IN DISASTERS! THIS HERE IS A RACE! YOU SEE, HERE AT TRAINING GROUND GAMMA, THE TESTING AREA IS A FACTORY SETTING! IT'S A LABYRINTH IN THERE! YOU WILL BE COMPETING IN GROUPS OF FIVE! I'LL FIRE OFF A DISTRESS CALL FROM WITHIN THE TRAINING GROUND! YOU WILL DO WHATEVER IS NECESSARY TO GET THERE! HOWEVER, PLEASE KEEP THE PROPERTY DAMAGE TO A MINIMUM!" he instructed.
A few minutes passed. "EVERYONE IS TO GO TO THEIR POSITIONS!" All Might instructed. Izuku stood at his starting place. Sero, Iida, Mina, and Ojiro were all in separate positions. "Man, this group has a lot of maneuverability…" Sato said. "Indeed. All Might must be putting us into groups with relatively equal mobility capabilities, so everyone has a relatively equal chance," Fumikage stated. "Even Midoriya?" Hagakure asked. "Hey, he can run on vertical surfaces. Remember the bottleneck?" Jiro asked. "He was also capable of sprinting at high speeds during the USJ," Momo replied, her hand resting on her chin.
"ARE YOU ALL READY?! BEGIN!" All Might shouted, pressing the 'go' button. Sero took the lead first, using his tape to fly over the obstacles. "You know, that's a really good strategy," Shoji said. "So he had the advantage," Fumikage replied. Koda nodded. Inside the training ground, Sero was thinking the same thing. "It's like this course was tailor-made for me!" he exclaimed, just before a green blur shot past him, creating arcs of electricity. "What the!?"
Izuku hurried across the course, using a combination of Blacklight and One For All to propel himself forward. He still had no idea what technique he was using, though. It was for rapid jumps and sprints, that was for sure. 'It's a really good technique!' he thought. "I'm touched, kid." That almost made him drop. His eyes went wide at that, though. 'Stain!?' he mentaly screamed. "Enjoying my style? It was made for quick getaways after taking out my targets. I had been practicing the dodging for when I went for Endeavor, so it's nice to see it in use," the 'Hero' Killer explained. As Izuku was conversing with him, he mistimed his jump. 'Shit!' he thought, almost losing control, before his muscles re-aligned themselves, and One For All at 5% returned. 'W-what?! That was unconscious!' "Heh. You're welcome." Stain replied. 'Stain!?' Izuku thought. "Hey, I didn't know I could do this either. Don't worry, I'm not gonna take over or anything. I was just helping you run on autopilot," he explained. Izuku then landed, and took off again. He was moving as he wanted to again! "If you want control back, it's torn from me. It's like you have a safety. From what I can tell, all I can do is give you a 'nudge' the serial killer replied. Izuku mentaly nodded, before taking off.
"THANK YOU FOR SAVING ME!" All Might declared, handing Izuku a ribbon. He took it with stars in his eyes. "YOU ALL DID VERY WELL! THE IMPROVEMENT YOU HAVE ALL SHOWN SINCE THE START OF THE YEAR IS AMAZING! GROUP A, PLEASE LEAVE THE TRAINING AREA!" he instructed, before patting Izuku on the shoulder. "It's time to tell you everything about One For All."
After school, Izuku went to All Might's lounge. He hesitantly knocked on the door. "All Might?" he asked. "Come have a seat," the Pro said, quietly. He was in his skinny form. 'He seems… off.' Izuku thought to himself. He sat down on the stool he had been provided. "You've been through a lot these past few weeks," All Might said to Izuku. "I'm sorry I wasn't there to help you out."
"You don't need to apologize for that!" Izuku exclaimed. He then leaned forward. "More importantly, you mentioned One For All," Toshinori nodded. "I heard that the Hero Killer swallowed your blood during the attack." he said. "Actually I just spat it out," Stain clarified. "What about it?" Izuku asked. "Do you remember what I said to you when I gave you my power?" Toshinori asked. Izuku said nothing. Instead, he stood up, and Blacklight rushed over him with a whistling sound. When it receded, Toshinori was shocked to see his Muscled form! "EAT THIS!" Izuku-as-All-Might declared. And it was in his own voice too! "No! No… and how did you do that?" he asked. Izuku shifted back to his normal form. "As it turns out, I can mimic the form of someone with just a little bit of DNA. If don't need to fully consume them anymore. I don't know how I knew that… I just… did," he explained. Any ideas, Stain?' He mentally asked. "It may have to do with my Quirk. I can paralyze someone by licking their blood. Maybe your Quirk took it and made it so you disguise yourself with a similar amount of DNA," Stain explained. "I have a theory, but I'm not sure," he replied.
"Very well. What I meant was that you ingested my DNA." Izuku's eyes looked down. "I wouldn't worry about Stain having One For All. I took his DNA after the fight. All of it," Izuku answered. "I heard the actual report, Izuku," Toshinori replied. 'It was only after Torino tipped me off about the cover story, though…' "And don't worry. One For All doesn't work like that. The power can only be passed on willingly," he explained. Izuku nodded. "On a related note, I think it's time to explain how One For All came to be. You see, the Quirk was originally different," he said. "How?" Izuku asked. "The origin of One For All is related to another Quirk, All For One." There was a very clear edge in Toshinori's voice. "This Quirk allowed its user to take Quirks form other people, either for himself or for others," he explained. "He could steal powers!?" Izuku exclaimed. Toshinori nodded.
"He was born during the earliest days of Quirks. During this time, Quirks were still seen as new. There was an age of chaos. Many nations during this time either collapsed outright or had revolutions. Society stagnated. I've heard people say that if Quirks hadn't appeared, we'd be interstellar by now. During this period of chaos, new nations arose. As you know from history lessons, The American Republic was formed when the United States of America annexed Canada and Mexico, both of which had collapsed. It also gained control of Western Siberia, after that faction requested annexation. The Eastern European Federation was formed during this time when the nation of Poland annexed Lithuania, Estonia, Latvia, Ukraine, Belarus, Moldova, and the Russian territory of Kaliningrad. The Chinese Federation was formed after the Republic of China took over mainland China, following a democratic coup in the mainland. Russia dissolved into a 5-way civil war, one of which was annexed by the American Republic upon request, as I mentioned previously. Most of Western Europe dissolved into small nation-states. South Korea annexed the north. In fact, Japan was lucky regarding stability. However, it was still very chaotic. During this time, a man appeared. He had the Quirk All For One, and used it as his name. I don't know his birth name. I don't think anybody but himself does."
"He used his power to spread his influence over Japan. Soon, he was ruling it from the shadows." Izuku gasped. "The Dark Shogun… I've heard rumors about him, but I thought he was made up!" he exclaimed. "That is part of the shameful history we'd rather ignore," Toshinori explained. "During his reign, he would hold his influence by exchanging these powers. However, some people couldn't handle the mental strain of their Quirks. They became like living dolls, perfectly obedient to him. Just like the Nomus." Izuku gasped again at that. "It was discovered by him that sometimes, two Quirks would merge with each other, becoming something new. This is best seen with his sibling. You see, All For One had a younger brother. He was weak, Quirkless, and sickly, but had a strong sense of justice. Then, All For One gave him a Quirk, one that would allow him to stockpile power. I don't know why. Was it to get him to submit? Was it to help his brother? It doesn't matter. What matters is that the brother wasn't Quirkless."
"Don't tell me…" Izuku began. "Yes. The brother had an invisible Quirk. He had the power to give his Quirk through DNA to others. These two Quirks merged, and One For All was born!" Toshinori exclaimed, throwing his hands wide. "Wait! You said that he was around during the beginning of Quirks! Why are you talking about him like he's still alive! He must be long dead!" Izuku declared. Toshinori shook his head. "There are Quirks that extend life and reduce aging. He must've gotten enough of them, or found someone with a legitimate immortality Quirk. I don't know. His younger brother entrusted his Quirk to another, hoping that eventually someone would be able to defeat All For One. Eventually, it was my turn. I fought that monster. I nearly died." he replied, clutching his side. "You mean-" Izuku began. Yagi nodded. "He gave me this wound. But I emerged triumphant. I thought I ended him… but now it's become apparent that he's back. He's the one behind the League of Villains." With that, Toshinori stood up.
"So now you know. One For All's purpose is to defeat All For One. I'm sorry, but one day you will most likely have to fight against this great evil yourself, because I failed… just like every One For All user before me. I'm sorry for this burden-"
"I'll do my best!" Izuku declared. That interruption brought All Might up short. "I'll fight this monster when I'm ready. I'll finish what the first brother started!" He declared, face full of determination. Toshinori stared at his protegee. That determined face was too similar to… he cut that thought off.
A few weeks passed. Eventually, it was almost summer vacation. "All right, so summer is coming up soon." Aizawa said. "But don't get too excited. You're not going to be lax with your training. We'll be going to the woods to do training there." Everyone was pumped for that. Aizawa fired off Erasure, silencing everyone. 'Thank you, Midoriya.' he thought, once again happy that he no longer had to deal with dry eyes. "However, Those of you who fail the final exam will have to take summer school."
That night, in a hidden location, All For One was speaking to his doctor. "So the Hero Killer was consumed by my son… I must admit I wasn't expecting that train of events to happen. Neither was I expecting Stain to call Izuku his legacy… it doesn't matter. Stain was was seen with the League, so young Tomura must be ready to unify those who are attracted to it due to Stain,," Hisashi explained. His doctor chuckled. "You know, it's a shame we didn't find the super regeneration Quirk five years ago. Now that your injuries are mostly healed, it wouldn't do anything for you," the mustached man replied. "Indeed. Then All Might wouldn't have stolen five precious years of my life, and I wouldn't have to keep lying to Inko and Izuku…" The doctor nodded. "So are you sure Tomura can pull it off?" he asked. "The boy was born with a twisted personality. It was important that I molded him into the next symbol of Evil… enjoy your peace, All Might… because it'll soon come crashing down on you…"
"Alright, so your exams are in a week. I hope you are all prepared." Aizawa droned. Of course, the class began to split. Those who did well on the midterms, such as Momo, Izuku, and Iida were alright. Those who barely scraped by were… less than calm. "Arrgh! With everything that's happened this semester I barely had time to study!" Kaminari wailed. Shinso was on the verge of a breakdown. "I wasn't here for the first third of the year!" he howled in despair. However, he just joined the impromptu hoard of students asking Momo for help.
At lunch, Izuku was eating with his friends. "Well, the written exam should be alright." he said. "After all, it'll probably just cover what we've gone through in class."
"Do I count as cheating?" Izuku's resident killer asked. 'I don't think so? I mean, you're technically a part of me now…' "I-is it really going to be that simple?" Uraraka asked, trembling. "Well, there's still the practical," Hakagure replied. Tsuyu nodded. "We'll have to stay in great shape for it." Izuku replied. He then got hit on the head.
"Oh, I'm sorry. Your head's so big it's hard to miss," It was Monoma. "Where's the suckup of 1-A? Is he not here? Or is he just… busy?" Everyone got what he was implying. "If you're so insecure that you have to claim one of our classmates had to engage in oral sex with our teachers to get here, then go." Shoto replied. Everyone stared at him. "Since mocking students who actually try hard to get to their positions and are actually trying to be heros makes him feel like he's actually worth our time, I suggest we just ignore him." he finished, still in his stoic position. Before Monoma could react, Kendo knocked him out again. "I'm so sorry about that." she said. 'Is he out cold!?' Izuku thought. "Yep. Boy, she's got a mean chop," Stain replied, whistling. She then waved, and walked off, dragging the unconscious form of her classmate with her.
The written exams were taken over three days. Izuku did alright. He had studied hard, and he had someone whispering answers in his head, so that was a plus. Of course, he only asked Stain for help when he needed it. Finally, they were done. "Alright, pencils down everyone. Those in the back are to pass the papers forward," Aizawa explained. "We will now head towards the practical area."
When the class, in their hero costumes, arrived, they were surprised to see all of the teachers there, in their costumes as well. "Uhh… why are the teachers here?" Jiro asked. I can answer that!" A squeaky voice declared. "Principal Nezu!?" several class members shouted. "Yep! That's me! The one who could be a mouse or a dog or a bear-" Izuku raised his hand. "You're a stoat, sir," he replied. Nezu opened his mouth, paused, and then sulked. "How did you know?" he asked. Most of the teachers were shocked! 'No one has ever figured it out! It wasn't even on the betting list!' they all thought. "Your fur, your size, and your general ear shape, sir." Izuku explained. Nezu stopped sulking. "I am impressed, Midoriya! No one has ever figured it out! I know the teachers had a betting pool, but you're too young to gamble. Thus, just know that I'm impressed! Now then, I will explain what you will be doing. Most of the midterm exams were spent fighting robots, but I decided to change that! You students will be working in pairs, fighting together, so as to take one of your teachers down! Isn't that exciting?!" He exclaimed. "W-we're fighting our teachers!?" Uraraka exclaimed.
"Yes, and don't think about choosing your partners or opponents. They were chosen by me with various factors in mind. For example, Yayarozo and Todoroki are a team… against me," Aizawa replied, smiling. "Oh, by the way, thank you Midoriya. The extra layer above my eyes is going to be quite helpful." Momo opened her mouth, but Shoto decided to interject. "So you'll be able to have your Quirk on full time… instead of needing eye drops every fifteen seconds." Aizawa opened his mouth, paused, and closed it. "Point taken. Next is Bakugou and Midoriya. Their opponent is none other then-" And then All Might dropped down. "I AM HERE! TO FIGHT!" Izuku looked terrified, but Bakugou just started to laugh. "All Might! Seriously!?" He howled with glee. "YOU SEEM VERY CONFIDENT IN YOURSELF." All Might said. "Me? No no no. I know I stand less than zero chance against you. But Deku? You. Are. Screwed," he declared, a snarl on his face.
"Now then, I shall announce the teams that shall be fighting, and the order in which they will be fighting!" Nezu declared. It seemed random, but there was still a pattern. It was right on the tip of Izuku's tongue, but he couldn't figure it out! "Now that the teams are put together, let me explain the rules! You will each have thirty minutes! You will be putting these handcuffs on your teachers, or you can escape the training area! Either one counts as a win! Also, if one of you escapes, it is counted as a win! Now, I bet you're all worried about us, and are probably already deciding to leave! Do not worry! The support course has created these weights!" Nezu declared, holding them up. "Each one is half of the weight of the person wearing them, so they are designed to slow us down a little and eat away at our stamina! We held a competition, and support class member Hatusme won! She's very talented!" Nezu reported, finishing. "Sato. Kirishima. You're up," Aizawa droned. "Yes sir!" the two boys in question responded. "One more thing- you can either strategize while you're waiting or watch the battles." With that, the students began to prepare.
"Alright Deku. Here's what I've thought up. I've been watching All Might closely, and there are some things you do that scare the hell out of him. Mannerisms, quotes, that sort of thing. If there's anything that terrifies him, use it."
The first fight was Sato and Kirishima verses Cemetoss. Cemetoss won that one. Rushing in caused them to lose, and badly at that.
Next was Tsuyu and Fumikage vs Ectoplasm. Thanks to some long-term thinking by Tsuyu, and Dark Shadow's mobility, they passed.
The next matches continued, one by one. 'There's a pattern here! I know it!' Izuku mentaly screamed. Stain nodded. "The matches seem random, but it's like there's an invisible force, guiding the outcomes," he explained. Finally, the match that pitted Shinso and Sero against Midnight began.
As soon as the buzzer rang, Sero and Shinso's plan began. Shinso just casually walked up to her. "Hey sensei, isn't embarrassing for an old hag like yourself to wear such a revealing outfit?" Shinso taunted. "Why, I can see your wrinkles!" Midnight damn near burst a blood vessel. "What did you say about me you-" and then she stopped. Shinso calmly walked up to her, and held out the handcuffs. "Put these on," he ordered. She did so. As soon as she was done, her eyes refocused. "What?" she asked, feeling the extra weight. Shinso had a shiteating grin. "You lost~!" He cooed. Everyone was sweat dropping at that. "He really got under her skin…" Izuku deadpanned. Bakugou laughed. "It's as you said Deku, talking isn't a free action!" With that, they both headed towards the entrance area, as they continued to plan.
They soon finished their plan. "Nervous?" Katsuki asked his friend. Izuku nodded. "You w-want me to intimidate All Might! How am I supposed to do that?!" Izuku questioned. Bakugou thought. "Can you transform into your dad?" he asked. Izuku sweatdropped. "Kacchan, I highly, highly doubt my dad would intimidate the Symbol of Peace." he deadpanned. "Yes, but it isn't going to help."
"Can you at least copy his angry face?" he asked. Izuku paused, and shifted into his father, and gave his best impression of an angry Hisashi. Katsuki started to sweat. "T-that's good," he replied. "Should I throw in the voice?" Izuku asked, sounding exactly like his dad. "Do you want me to piss myself?" Katsuki responded. "Is that a yes?" Izuku asked. "Fuck yeah it's a yes!" Katsuki answered, which prompted Izuku to shift back. The two nodded, and headed into the training area. "So, how much do you think this is going to work?" Bakugou asked. "Well, unless All Might managed to 100% bury his heroic spirit, I'm going to say it's going to work flawlessly," Before they could continue, a gust of wind blew at them. When the smoke cleared, the two were separated.
"WHO CARES IF I DESTROY THE CITY!?" All Might shouted. 'Holy crap… that's intense!' Izuku thought. "IF YOU REALLY WANT TO PASS, THEN YOU'LL HAVE TO COME AT ME LIKE THIS IS AN ACTUAL BATTLE!" he declared. "Deku! Get going on that terror! I'll distract him!" Katsuki shouted, charging at All Might. "OH? SO YOU'RE APPROACHING ME?" All Might asked. "I can't beat the shit out of you without getting closer!" Bakugou roared. All Might grabbed his face. Bakugou snarled and fired off several rapid stun grenades. "THOSE WERE WEAK. LIKE THE BITE OF A FLEA." All Might taunted. 'I'm impressed with his ability to not instinctively go for the face,' All Might thought. "NOW WHERE ARE YOU MIDORIYA?" he asked. All he heard was soft, slow clapping. "Well done, All Might. Well done." And then, he dropped Katsuki. 'No…' And from the smoke, All For One, fully healed, walked forth.
'Ok, he's really off put by my dad… probably due to the fact there's a random citizen. "Surprised?" Izuku asked in his father's voice. "To think that the great Symbol of Peace is attacking children! My oh my how the mighty have fall-" he was cut off when All Might bisected him. Straight down the middle.
At the testing area, everyone was interested. The cameras had caught Izuku shifting, and they were confused on how taking the appearance of his dad would help. They were confused about how All Might's face went from faux-villainous, then to shocked, horrified, and finally to enraged. And then they gasped in horror when he bisected Izuku.
"Surprised?" the Symbol of Evil asked. 'Izuku!? Where is Izuku?!' All Might mentally shouted. "To think that the great Symbol of Peace is attacking children!" At that, All Might forgot this was an exam. He forgot this was UA. All he saw was the monster that killed Nana. "My oh my how the mighty have fall-" and he ripped that bastard apart. 'That was too easy,' he thought. And then his eyes widened as a familiar whistling rang through, and All For One became Izuku.
