It was a great feeling of suspense hanging in the air around the yakuza base. The raid group had assembled just a few minutes prior, but they couldn't enter yet. "When is the warrant coming?" Sir Nighteye asked one of the police officers. "Should be coming soon" The officer answered. As if on cue a man walked up to the building with a sheet of paper. "The moment I'm finished reading the warrant, you'll attack their base" He said. The man reached out his hand to ring the doorbell when a massive figure, several meters in height and with a bird beak mask, smashed the door open, making several police men fly away. "What are you doing here!" The massive figure shouted. Izuku, Aizawa and a couple other heroes saved the policemen that had been hit while Ryukyu turned into her dragon form and began dealing with the villain. "My group will take care here. The rest of you must continue" She said.
The rest of the raid team followed her orders and continued onwards into the building. There were several yakuza members they encountered who attacked them, but they were quickly taken care of. Eventually they found the secret entrance to the underground part of the base. Si Nighteye pulled out a book in a bookcase and it opened like any normal door. Two more yakuza members came out from behind the secret entrance. They were taken care of by two of Sir Nighteye's sidekicks and the raid team made their way down under ground.
For some time things were quiet, too quiet. After a few minutes with no encounters with anyone, the walls and halls started shifting a moving. "What's this!" Kirishima exclaimed. "It's one of the eight precepts. One of them can manifest objects and change it any way he wants to. He must have taken a drug to boost his quirk" Sir Nighteye responded. "Keep moving!" He ordered. The team tried to keep going forward, but the hallway was closing in front of them. Mirio ran phased straight through. Izuku followed soon after, throwing a set of explosives into the closing hole, blowing the hole big enough for him to pass through before it closed behind him. Once he had gotten away from the shapeshifting hallway he could see Mirio running ahead. Izuku didn't waste time and followed.
It didn't take long until there was an intersection in the hallway, going left and right. Mirio ran straight ahead and phased through the wall, leaving Izuku alone. "Which way is it? Sir Nighteye isn't here to show the way" Izuku slightly panicked to himself looking down both ways. Eventually, he decided on a way and started heading down the hallway to the right. It seemed like it went on forever. Even when using his odm-gear as fast as he could in the cramped space, it didn't seem to change. Izuku decided to turn around and try the other way, but when he turned around he saw something else, a rooftop.
"What's this? It looks familiar" Izuku said to himself and walked onto the rooftop, suddenly feeling the wind blowing around him. "If you can become a hero without a quirk?" an all too familiar voice said behind Izuku. He turned around just in time to witness one of the worst moments of his life. "I don't think so. It is fine to have dreams, but you have to keep them realistic. I can't tell you to become a hero when it can kill you" All Might said while looking down on a different version of Izuku. None of them seemed to notice the real Izuku standing there, who started tearing up at the memory. "NO!" He yelled. "He was wrong, and he apologized, this is behind me" Izuku told himself and looked for a way out, when the scenery changed.
Izuku was once again looking at another bad memory. His 4-year-old self, looking at the same All Might video again and again with teary eyes and his mom looking on with sadness. "M-mom? C-can I become a hero like him?" The young Izuku asked while pointing at the screen. The younger Inko ran over and hugged young Izuku while crying. "I'm sorry Izuku!" She yelled out. "Wait, that never happened, she didn't say that, she supported me, she has always supported me" Izuku said to himself without emotion before the scenery changed once more.
Izuku was now looking at himself laying completely exhausted and with burn marks on one of UA's training grounds, while his classmates and Aizawa watched him. "I don't remember this" Izuku muttered. He then started hearing his classmates talk among themselves. "How did he even get in?" "He shouldn't even be here" "Quirkless people can't be heroes" "When will he learn" They all said, some with almost disgust in their voice. Aizawa then walked over to Izuku laying one the ground and looked down on him. "Give it up kid. One more training like this and you're out. It's for your own good" Aizawa said with no empathy at all.
The real Izuku looked on the scene in shock and slowly backed up until he tripped on something and fell on the ground. When he stood back up the scenery had changed again. He was now looking at the ruins of a city, with rubble and pieces of buildings laying on the ground. Izuku was looking around in shock when someone grabbed his leg, making him quickly turn around. "D-deku" Bakugo grumbled, before his body fell completely limp. Izuku then looked around Bakugo and saw several bodies of people he knew, friends, classmates and other heroes. He kept walking through the carnage until he saw one that made his body want to curl up. Ochako was lying lifeless and dead on the ground, with huge gashes in her body. Izuku could even see her bones sticking out of her mangles legs. He immediately fell on his knees and let out a blood curdling scream. He kept screaming and crying until he was no longer able to continue.
"Such a shame. They fought so well. If only you could have been more useful" A familiar voice, that Izuku couldn't quite place said right behind him. The voice then let out a sinister laughter. "Who am I kidding. You're useless as always. If only you had a quirk, then maybe she would have survived" The voice taunted in a sinister tone. Izuku closed his eyes and tried to block out everything. "SHUT UP!" He yelled, but it only got worse. More voices started speaking to him. Voices he knew and voices he didn't all kept telling him to give up, calling him useless, telling him to kill himself. Izuku thought his mind was about to break, when thing quieted down until he could only hear weak crying from a small child.
Izuku slowly opened his eyes and saw the source of the crying. It was himself when he was around six years old. It must have been after one of Bakugo's beatings Izuku concluded. The young Izuku slowly stopped crying and brushed of his tears with his hand. "I don't care how long it will take. One day Kacchan, I will become a great hero, for everyone" Young Izuku said quietly to himself while looking towards something Izuku couldn't see. "I'm right. I have to focus on what's important" The real Izuku said to himself and looked at his younger self with a smile. "This is all just a bad dream" He said and pulled out one of his flashbangs and activated it right in front of him.
Izuku was pulled out of his nightmare in an instant by the blinding light and sound. Luckily for him, he had accidentally activated his flashbang several times in the past while making them. Meaning that he recovered far faster than whoever was responsible of the illusions. Izuku looked up and saw one of the eight precepts recovering after the flashbang. "How did you?" The yakuza said before being knocked out cold by Izuku. "Don't do that again" He said before moving on to find Mirio.
Finding Mirio turned out to be easier than Izuku had first thought, since he could hear Mirio fighting with someone ahead of him. On his way to the fighting Izuku passed another one of the eight precepts. This time knocked out, most likely by Mirio. "Mirio is really strong" Izuku mumbled to himself. He then heard Mirio yelling further down the hallway "I won't let you hurt her!" Izuku didn't waste any more time and immediately went towards a big room were the fighting was taking place. The first thing he noticed was that the entire floor had changed into big spikes due to Overhaul. He then saw Mirio in one end protecting Eri with his cape while Overhaul was standing in the other end.
Just as Izuku was about to go help Mirio he heard a gun being fired and noticed something going through Miro, who was unharmed due to his quirk. Izuku quickly found the source and saw one of the eight precepts of death loading a gun with some sort dart containing liquid. 'Must be the quirk destroying drug' Izuku thought. But then, to Izuku's surprise, the yakuza member pointed the gun at Eri. Mirio immediately ran in front of the little girl just as the gun was fired. To Mirio's surprise however, Izuku came in front of him just in time and got hit by the dart. Meanwhile, Izuku could only smile 'He is worthy' he thought.
"What was the point of that hero? Now you will lose your quirk" Overhaul commented with some slight annoyance. "Have you been living under a rock or something? I'm already quirkless" Izuku replied with a smirk. He then quickly charged the yakuza member with the gun and knocked him out while also destroying the drugs with a small bomb. Except for one dart. "It's bad enough being forced into being quirkless by life, I won't let any more people being forced to share that destiny" Izuku said. "You both are just ignorant children who know nothing about the world. Quirks need to be eradicated!" Overhaul shouted. "You are just a monster who abuses an innocent child for your own gain. It is my duty as a hero to protect her from people like you and I will. Dekiru, let's take him together" Mirio replied. Izuku just gave a small nod as they both charged at Overhaul.
Overhaul put his palm down on the ground and the entire floor turned into small pebbles before reshaping itself into a new set of spikes, forcing Izuku to stop. Mirio phased through them and came ran right up to Overhaul. The Yakuza leader tried touching Mirio, but his hand just went straight through. Mirio then delivered a series of punches to Overhaul before moving away again. "You will just tire yourself out" Overhaul said and used his quirk on himself. His entire body blew apart before going back together without the injuries Mirio afflicted. "Why aren't you protecting the little girl, hero?" Overhaul taunted and moved his palm back down to the ground. Before he could use his quirk again however, all of the floor surrounding him blew up and was turned into small pebbles. "You should keep track over your opponents" Izuku said holding a few explosives in his hand and threw them at Overhaul. The yakuza leader took the blast before using his quirk on himself again. "As I said, it's no point in continuing. When will you learn that?" Overhaul asked. "When will you learn that there is no point in saying that?" Izuku replied, making Overhaul grumble.
The fighting continued for several minutes without any side getting the upper hand. Overhaul had no chance at hurting Mirio and Izuku kept his distance. Meanwhile Izuku and Mirio couldn't do any lasting damage on Overhaul due to him dismantling and reassembling his own body. "Can you distract him for a moment Lemillion? I have a plan, I just need him to have his eyes on you and not me" Izuku asked. "Sure, should be easy enough" Mirio replied and charged at Overhaul one more time.
While Mirio was keeping Overhaul busy, Izuku made his way to the last dart of the quirk destroying drug and took it. Izuku then went behind Overhaul and charged at him at full speed. But then Overhaul quickly turned around and tried to grab Izuku. Izuku then threw the dart towards Overhaul. The yakuza leader then desperately tried to catch the dart, but right as he was about to grab it, Mirio grabbed it and injected Overhaul with his own drug. "Nooo!" Overhaul yelled as he saw the liquid go into his body. "What's the problem? Didn't you want to remove quirks?" Izuku asked and landed in front of Overhaul. The yakuza leader tried to use his quirk one last time, but nothing happened. "This is how being quirkless feels like" Izuku said before knocking him out cold.
Not long after Overhauls defeat all members of the eight precepts of death was taken to prison. Meanwhile, Eri and all heroes that was a part of the raid was taken to a hospital for treatment. One of those was Sir Nighteye who had been fatally wounded during the raid. A few hours later, he was dead. Before he died, Izuku managed to tell him that Mirio would receive One for all. So, when he died while surrounded by Izuku, Mirio and Toshinori, he died with a smile.
"Toshinori, he is worthy" Izuku told Toshinori while they were standing in the hallways of the hospital. "You sure?" Toshinori asked. "I saw him about to sacrifice his quirk just to save Eri, without hesitation. You said that I should look for a moment of true heroism and I have seen it. There is no better alternative" Izuku explained. "And it was Sir Nighteye's final wish" He said with a saddened tone. "You're right Midoriya. You sure you don't want it? Once I have given it to him there is no going back" Toshinori asked. "How many times must I tell you? I don't want it" Izuku replied. "I know. I just want to be sure. I'll give it to him at the beach. You should probably be with me since I think he would want you to have it" Toshinori said.
The next day Izuku and Toshinori on Dagobah beach, waiting for Mirio. "Sorry for the wait. Had trouble finding the way" Mirio apologized as he walked up to the duo. "What was it you wanted to say?" He asked. "Do you know how my quirk works Mirio?" Toshinori asked. "Some strength enhancer, right?" Mirio replied. "Well not exactly. You see, my quirk was given to me like a sacred torch passed down from one generation to the next. Each time it stores more and more power, becoming more and more powerful. It is called One for all" Toshinori explained. "Why are you telling me this? Isn't this something... Wait. You want to give it to me, don't you? Why won't you give it to Midoriya? I already have a quirk, there is no reason to give it to me" Mirio asked with confusion. "There is a reason to give you One for all. You act like a true hero, always making those around you smile. And above all, you did an act of true heroism when you protected Eri from Overhaul. You were even willing to lose your own quirk to save her. It was also Sir Nighteye's dream to see you use it and become a great hero" Izuku explained. "I see" Mirio said. "But still, you don't have a quirk, you deserve to get One for all" Mirio protested. "Don't you wonder why I know about the quirk? I have already been offered it, but I don't want any quirk. I want to show the world that quirkless people aren't useless and that's the one thing I can't do with a quirk" Izuku said. "Okay then, I will take it" Mirio replied. "Great! That's what I wanted to hear" Toshinori exclaimed and turned into his hero form for the last time and pulled out a strand of hair. "Now. Eat this!"
