"And then you get your stupid self captured, again, is it possible for once that you don't screw up every plan of mine," Izuku shouted at Bakugou, pulling him away from the League of Villains who were confused how one of the hero brats managed to sneak up on them so easily. To them it would seem as if this person appeared out of nowhere. "Now get the hell out of here so I can do my job." Ordering Bakugou moments before the members of the League attacked Izuku who vanished before he could be hit.
"Go outside and take a left, once you get to the corner flag down Ninjavore, she'll be headed down that road in eighty-three seconds, after that go right, head into the coffee shop and dial 001-974-2223, tell them the coordinates, thirty-four, sixty-eight, seventy-one, four by one hundred thirty-five, fifty, sixteen." Izuku instructed while he acted as a distraction for Bakugou to move across the bar, grabbing two bottles from the shelf he appeared in front of onto Twice and Dabi who were moving towards their escaping prisoner. Smashing the bottles together shattered the glass and created a fine mist of alcohol that doused everyone around him.
The fire user had planned to ignite the brats, but now being covered in a highly flammable liquid and with every clone Twice made being as equally covered in it, the entire bar was nothing more than a powder keg waiting to go off.
A twist of his body and Izuku had knocked the knife from Himiko's hand,gripping her wrist and giving a sharp yank he pulled her arm out of the shoulder socket with her recoiling from the pain Izuku planted his foot in her gut, sending her to the floor winded.
Shigaraki screamed in frustration now that he could see that his hostage was getting away from, but before he could run after Bakugo, Izuku moved to block his path. "Hello, Shimura." Izuku nodded. "To think you were the grandson of All Might's teacher. Whatever the hell Shigaraki did to you, I'm truly sorry that you had to suffer, but you're a monster and I have to stop you." Izuku pulled out a stun baton and stabbed it forward.
The confusion in his mind at being called by his old name was almost enough to make him falter and get struck by the rod, but he was barely able to avoid the strike that would have incapacitated him before he started to shout and scream at this child for knowing things he shouldn't.
"Dammit, well I tried the peaceful route," Izuku shrugged because his one shot at taking down the villain without risking himself had passed. With that possibility taken from him he pulled out two smoke canisters and pulled the pins causing them to spew purple mist into the air. "I wish it didn't have to be this way."
"What is this?" Shigaraki snarled out, recoiling from the new element and covering his mouth while looking around for an exit.
Izuku had vanished again and reappeared on the other side of the bar by the only way out, the windows had already been sealed up by himself earlier. "A concentrated version of Ms. Midnight's quirk, something I finished a few years from now, it was supposed to be the last resort. Normally her quirk would put you to sleep, like a sedative, but at this level, your lungs will just stop." Izuku said sadly before he stepped through the door and closed it, he looked upon the room of villains who were struggling to move out of the bar after Izuku hit them in ways that would slow them down, allowing the gas time to take effect. "I'm genuinely sorry it had to end like this, but it's safer for everyone this way." Closing the door he disappeared from the location, his work done, finally after so long it was over.
Shigaraki pushed against the wood and found the door to the bar had been barred, preventing it from opening. "No, no, nonononono," He ranted through his weakness while he tried to decay the wood, but once he created a big enough opening, his arm slipped through. but by then he was too tired to pull it back and make the hole bigger.
The last thing Shigaraki heard was the sound of a massive explosion in the distance, a large warehouse had been struck by an MOP-432, a weapon specially designed for penetrating deep into underground enemy bases, its explosion killing all inhabitants inside from the force of the blast pulping their organs, and with the massive fire caused by all the chemicals reacting with the explosion and then finally burying them under tens of thousands of tons of rock. Izuku let out a sigh, looking across the destruction he had caused, realizing that he caused the deaths of numerous people, but he had to accept that this was for the best. If he had let things go on too long, even he didn't know the long reaching consequences of what would happen.
He carried Ragdoll's unconscious body towards arriving emergency services and disappeared once more as soon as he wasn't being watched.
"Sweetie!" Emi called out in concern the moment she saw Izuku step into her living room, she and her kids were watching the news report about the senseless destruction caused in the nearby city. His disheveled appearance and how he dragged his feet sent the alarm bells in the heroine's mind ringing.
"It's done, he's gone," Izuku sighed as he fell into Emi's arms. "I had to kill a lot of people today to make it happen though."
"What exactly happened?" Todoroki asked her classmate and future step-father.
"All for One, the person who created All Might's quirk, I used an old automated military system created by the Russians about a century ago to call in a powerful bomb to level his lab," Izuku explained. "Him and that doctor who made the nomus are dead now, as for the League, they died peacefully at least, all of them were as much victims of this god damn battle just like everyone else had been."
"So it's done?" Emi gently rubbed her lover's hair while he laid limply next to her.
"Maybe, I still have One for All, it seems that I didn't need it after all. All for One never even got a chance to try and take my quirk from me."
"Wait what?" Fuyumi questioned. The Todoroki children had gotten used to Izuku coming by suddenly along with saying and doing strange things, but this was starting to go over her head.
"Oh, well All for One, a guy who was born about two hundred years ago, his quirk, let him take other people's quirks, perfect for a villain, he took a ton of quirks to keep himself alive. He had a brother, who he thought was quirkless and just to be a dick gave him a "useless" quirk that stockpiled power, however the brother actually wasn't quirkless. Funny enough his quirk allowed him to give his quirk away, kind of poetic isn't it, one gives, the other takes."
"Anyway, the first wielder, realized how insane their brother had become and each time this quirk which is now called One for All, is passed down it gets stronger and stronger, each wielder hoping to be the one to put an end to the madness. It has another benefit, it prevents All for One from taking the quirk back, not entirely sure how, but with my time travel quirk."
"Oh damn, a time traveling immortal super powerful villain would be unstoppable," Natsuo realized what could have happened if this person Midoriya was telling them about had gotten his hands on a quirk like that.
"Exactly," Izuku nodded. "It's why I had to let certain events play out, I had to get All Might to give me the quirk, to prevent All for One from ever getting it."
"How much did All Might know?" Emi inquired, wondering if her rival had been more involved with Izuku's life than she had been.
"None of it, I'll have to tell him though. He deserves to know that this nightmare is over though." Izuku sighed as he started to sit up until two firm arms pulled him back down.
"Later," Emi scolded. "You've had a busy day, you can tell them all tomorrow."
"Okay," Izuku relented without much fuss before he nestled into Emi's body. "Oh, I got Ragdoll and Bakugo out before it all went down, that way only villains died. I couldn't get to her before All for One took her quirk though," he sadly added that he was unable to fix that detail but it would have required him getting to her before All for One did which he couldn't be sure was possible and was too much of a risk to try.
"Then you did the best you or anyone else could do, although if Bakugo died, it wouldn't have been a big loss." Emi snorted derisively.
"Emi," Izuku whined tiredly even though she was mostly joking.
Emi shushed the young man in her arms. "I found out all the crap he put you through over the years, he's a bastard, you are practically a saint for still saving him."
"Had to be done," Izuku yawned just as his eyes fluttered closed.
"Get some rest, I'll have some food delivered," Emi said as she pointed to one of her kids to get their phone out so they could call for some dinner.
There was a small celebration at the Todoroki household that night, a major villain had been defeated, his network of evil resources eliminated and his protégé was removed as a threat. However Bakugo's sudden return to his home resulted in the police questioning about what happened, this led him to admit that he escaped from the bar where he had been held captive, but he didn't implicate Izuku mostly because he wasn't sure what to say about that situation.
The heroes mounted an offensive on the bar and after reconnaissance they determined that there was no threat, and after they pulled out eight bodies from the establishment, this left the heroes and officers curious as to the culprit behind the death of these dangerous villains.
A few days later had Izuku and Emi walking up the path to the U.A. campus. "Are you sure about this?" the pro-hero wondered nervously because this wasn't just about informing All Might about the fate of his nemesis but also to reveal to the staff at the hero school their relationship.
"I'm sure it's fine, they apparently knew about us right away, so it's not that big of a deal." Izuku assured her diverting from the path that normally would have taken them to the classrooms and instead headed to the principal's office.
"Endeavor and... Mr. Midoriya," Nezu's lips twitched because this was not a combination of people he had expected to see this day, not with the absolute chaos his week was turning out to be, he'd hoped it had nothing to do with the relationship between Mr. Midoriya and Endeavor's daughter as he could only assume that was the reason for them being together.
"Hey Nezu, I need to confess some stuff, it'll probably be easier if Toshi is here as well. He'll need to hear it too." Izuku said as he took Emi's hand and seated the two of them in the office chairs in his room.
Raising an eyebrow in confusion at the affectionate display, Nezu pulled out his phone to call his staff members for a meeting.
"So what's the commotion, we're still trying to find out who caused all that destruction a few days ago." Snipe inquired why they were all being pulled from the task at hand.
"I can answer that, it's going to be a little awkward, but first," Izuku rubbed the back of his head. "Toshinori Yagi, I lied to you, and I'm very sorry about that."
"What do you mean you lied to me young Midoriya?" All Might questioned since he wasn't sure why his protégé was apologizing.
"I tricked you into giving me One for All, it wasn't honest and if you want the quirk back it is yours," Izuku said to the hero, reaching up to pluck a hair from his head. "Just know that I only did that to ensure that All for One did not take my quirk and end all of humanity."
The other teachers had been muttering among themselves for a while but All Might looked at Izuku confused. "But, you were quirkless when we met, you told me that yourself."
"I lied, I have a quirk, I can time travel, it's how I got to know Emi," Patting his girlfriend on her thigh. "After your death All for One felt it was needed to rub in everyone's faces your quirk, and after spending a few weeks in the rubble that used to be this school Nezu explained to me what your quirk would do, he told me that I had to get my hands on it. It was a literal race against time."
"Hold on," Aizawa interrupted, slamming his hands on the table. "Midoriya what the hell are you talking about?"
Izuku sighed and ran a hand through his hair. "Sir, the advent of quirks led to some interesting abilities forming in extremely rare cases. All for One was one such man, he was born with a quirk to steal other people's quirks or give them away. It was how he amassed so much power so quickly. I was born with a quirk that allows me to travel through time, when I saw the destruction and devastation caused by that man I knew I had to do something to prevent that from happening. With careful planning from Nezu we determined that after All Might's fight with All for One that would be when the man was at his weakest and wouldn't be able to plan around me should I fail initially."
Turning to look at the principal. "You had warned me that if I tried to confront him before I had gotten One for All from All Might that it ran the risk of him stealing my quirk because I wouldn't have anywhere close to the power needed to protect myself and too early would allow him to prepare for the eventuality of any later arrivals."
"Vlad, you were the one to give me the code to the Russian missile system that I used a few days ago." Izuku explained hoping that the details would get the other teachers to believe him.
The entire time Izuku had been talking, Present Mic had been enraptured, but hearing that last detail made him jump into the conversation. "You used to be a Soviet Spy?!" Because he always knew something was up with his colleague but that would not have even been his tenth guess.
The blood based hero cringed because he knew that only if he had told someone that information would they know it, meaning Midoriya was likely telling the truth.
Nezu was sitting contemplatively just content to absorb the information Izuku was saying. "So was that your doing with the League of Villains in the bar then?" inquiring into that detail.
Izuku nodded. "I wanted to take them in peacefully, but I couldn't waste time. It would have only given them more chances to escape. So I had to use what we came up with to put them down."
"Which would be?" Snipe asked.
"Before you died Ms. Midnight you wanted to help end the war, even without most of your limbs and organs, you produced as much of your quirk as you could, I was able to put those into gas cans. The League of Villains died in their sleep, the people who killed you… did not," Izuku answered the question even if it was painful for those memories to be dredged up, seeing what the savages had done to the once proud heroine.
"Fucking Christ kid," Ms. Midnight whistled because her imagination did not paint a pretty picture for what must have happened to her. "Thanks for avenging me I guess."
All the while All Might had been sitting in his chair quietly. "Young Midoriya." he finally said, drawing all attention onto him.
"Yes All Might?" Izuku nervously asked because he hoped that the hero he had grown up idolizing didn't hate him for what he had done.
"Keep the quirk," All Might sighed once he made his decision. "You did the world a lot of good with it and you'll continue to do so well into the future. You didn't tell me everything but you had your reasons. You didn't know what you could reveal so you played with your cards close to your chest to ensure you won, I can understand that. But in the future please know that we are here to help you."
"Thank you sir," Izuku exhaled in relief that All Might still had faith in him.
"Now onto the other elephant in the room," Nezu coughed and pointed to the intertwined hands of Midoriya and Endeavor.
"Oh that, well we're dating. I thought you knew?" Izuku looked around the room curiously.
"What, no?!" Ectoplasm sputtered. "What the hell gave you that impression?"
"But you guys. Shiiiiit," Izuku hissed. "I thought you guys had figured it out."
"NO!" the teachers shouted in unison.
"We thought you were dating Ms. Todoroki, not her mother." Recovery Girl said in exasperation. "When did something like this even start?"
"About 30 or so years ago." Emi smirked, taking joy in the confusion on the other heroes' faces.
"Time Travel, remember? I used to wander around all the time when I was younger, that was before everything went to shit. So I ended up one day running into Emi and we just… clicked," Izuku smiled at the woman he loved.
"He disappeared for a number of years, likely to help prepare for what he had to do to stop All for One," Emi said, taking over the conversation. "I wasn't in a good place for a while, but now he's back."
"So if that's all, I still have a few more days of vacation that I plan to wring him dry," standing up from her seat and pulling Izuku along with her. "I'll make sure he's back by the time classes resume."
"Well ain't that some shit." Snipe whistled once the door shut behind the two lovers.
"I know right?!" Present Mic exclaimed excitedly.
"I honestly thought this whole time she was such a hardass because she had a crush on All Might that he refused to notice." Ms. Midnight snorted out a laugh at the horrified look on the number one hero's face.
With the weight off their shoulders about discovering the cause of the previous day's events and with the looming threat of the League of Villains gone for good, the teachers were quite content to look the other way with the strange relationship between hero and student.
