Chapter 13: The end of a future Hero

Izuku woke up really exhausted. Toga was by his side, sound asleep… and naked. Izuku got up and walked to the Dojo. Stain has gone two days without cleansing the city. Izuku and Toga could not train today. Izuku felt like taking a walk, but he didn't want to leave Himiko. Izuku instead made himself some ramen and got his sword. Izuku took the same stance Stain does. He ran forward and stabbed a martial arts dummy.

"Woah. No wonder he's so fast".

Izuku got back up and grabbed his staff.

"Stain said that this sword can be used as my secondary weapon. If I combine my sword skills with bo staff skills, how strong could I get"?

Izuku spun around his staff and readied his sword. He looks towards the dummy and closed his eyes.

'Think Midoriya. What do I need to improve? My fighting skills need to be more than ready. I'm Quirkless, but not weak. I have to keep going! I need to be strong'!

Izuku ran towards the dummy and used his staff. 'Faster'!

Izuku used his sword and delivered a swift attack. 'Faster, Stronger'!

Izuku brought out more dummies and kept rushing each one. Each hit, stronger, faster, and more ferocious than the last. 'FASTER'!

The last dummy remained and in the blink of an eye, He sliced the dummy in half. "I did it. This sword is really amazing. I… what"?

Izuku looked at his left hand, which he used to slice the dummy. It wasn't the sword. It was his staff. "How the?... Holy shit".

Izuku felt proud of himself. He couldn't believe how strong he really was… really was?

'You are much stronger than you believe Izuku'.

All for One's voice popped in Izuku's head. He was right. After only two days, he's improved so much.

'Wait, my code to not kill… was that holding me back? I could do so much more'!

Izuku smiled and jumped in joy.

"MIDORIYA!"

'Oh fuck'.

Izuku looked back to see a pissed off Himiko. "Clean up this damn mess, Shut the fuck up, and STOP INTERRUPTING MY DAMN SLEEP"!

Izuku did as he was told and quickly ran towards the sliced dummies. Toga went back to her room and buried her face in a pillow. As Izuku finished cleaning up, he hesitated to put away his weapons. 'What the'?

Izuku couldn't stop staring at his sword and staff. It felt like he could do whatever he pleased with these two weapons. He felt unstoppable. 'Hmm. I know'.

Izuku went to his bag and grabbed his villain suit. He grabbed a few materials from the hideout and began creating a scabbard for his back. Ever since he began training with Stain, Izuku has studied his fighting style. Even if it was his third day with the Hero Killer, he has learned a handful of things from him. His everlasting goal of cleansing this world from fake heroes kept making him push his limits. Izuku's desire to not be seen as weak relates to that. Izuku started painting his sword scabbard and looked at the time. It was currently 3 Pm… 3 Pm?!

Izuku looked to Himiko's room to see that she was gone. There was a note on top of the bed.

"I went out to explore the city. I may have taken a few yen from your wallet. It's your fault for leaving it out. I'll be back by 9 Pm"~ Toga

Izuku looked at his wallet and frowned. "And… I lost 8,000 yen ($72.90 in U.S. Dollars). What is she gonna buy with my money"?!

Izuku got off from his bed and walked to his suit. He put on his spandex suit, combat boots, armor, and scabbard. Izuku equipped all of his gadgets and weapons.

"Woah".

Izuku looked at his mirror. He was left speechless. "Huh, I look good in black. It's funny. Hmm. I've always wanted to be a hero…, but now".

Izuku put on his hood and mask. "I have to be the one that fights them". Izuku grabbed his grappling hooks and left the building. "I need to test something".

~Hosu City (6:12 Pm)~

Stain stood on top of a water tower, staring down on the city.

"Hosu City looks nicer than I expected".

Shigaraki and Kurogiri appeared behind Stain.

"So, what are you gonna do?"

"I will reform this city. In order to do so, I require more victims."

"Where are the kids?"

"They should both be at my place. They both lack some parts, but they are extraordinarily strong. If I had to pick a favorite, however, It'd be Toga. She may not be as strong as Izuku, but she has a far more ferocious nature. She doesn't hesitate and knows exactly what she doing. Izuku still has that code to not kill. Even if I respect that, he's gonna need to know to let it go. In this world, you can't trust anything."

"Wow. That actually makes sense."

"I see you're one who understands. If we're going to work together then I apologize for stabbing you. Don't get in my way and I think we'll be alright. Deal."

"Deal".

Stain leaped into the air and looked for his next victim. "Hey, Kurogiri."

"Yes."

"I don't think he's actually sorry. He didn't seem to put any emotion in the apology."

"Stain isn't the emotional type. You shouldn't make fun of him either. The reality is that everywhere he's attacked, crime has gone down."

"Hmm, alright. I'll keep my end of the deal and not annoy him too much. Kurogiri, bring out the Nomus. We'll go to the city".

Three Nomus came out of a portal created by Kurogiri. One was skinny and crawled on the ground. Another was really bulky, similar to the one who battled All Might. The last one had wings and a gas mask.

"Let's see who wins. The crazy carnage going on in the city or another hero, dead, by the hands of the Hero Killer! I'm going to love this".

~Hosu City (6:20 Pm)~

The sun has begun to set and Izuku got off his train. He rushed towards a skyscraper.

"This'll work".

Izuku went inside the building and sneaked his way to the top. Izuku saw a janitor leave the door for the rooftop open and took the chance. He made it up and stared at the ground.

"Wow, it's not bad".

Izuku sat at the edge of the building and looked at the time. It was currently 6:22 Pm. He went through his contacts and found his mom's number.

*Bzzz*

*Bzzz*

"Hello?"

"Hey, mom."

"Izuku! I thought I told you to call me yesterday!"

"I know I got distracted. I was with Toga. Apperanity she had a big meeting in Hosu City. I went with her."

"Hosu City! Did you two eat? Sleep? Wait,... You two aren't sharing a room together, are you?"

"We have plenty of food, we got plenty of sleep… and yes, we are."

"... You two have protection?"

"MOM!" "I'm kidding! Have fun sweety…, but not to much fun ( ͡° ͜ʖ ͡°)."

"How did you say that out loud"?!

Izuku's mom hanged up. "Fine, keep your secrets".

Izuku put on his mask and readied his gear.

"I'll keep mine".

Izuku left his clothes on that building and… jumped. Izuku swan-dived towards the city. Izuku looked up and shot his carbon-fiber wire. He saw everyone looking up. Izuku hit another building and swung away.

"WOOOOOO"!

Izuku shot another cable but was too low to swing. He ran in the middle of the street and leaped up in the sky. He kept getting faster and faster. He shot another one while running on the windows of some Hero Agency. He reached another rooftop and parkoured his way through it and swung away again. Izuku landed next to some train tracks and took a break. He's never felt more excited in his life. Izuku stretched and began to put his mask on. As he did that, he heard an explosion and looked back.

"What the"?

He saw as a huge fire was happening in the center of Hosu City. "A Hero"?!

Izuku saw an incoming train and witnessed as a Nomu went inside a train and had a Hero in its hands. "Oh no".

Izuku put on his mask and made his way to that Nomu. The Nomu raised his hands towards the Hero's head, ready to crush it, in front of a dozen people.

"HEY"!

The Nomu looked up to see Izuku in his costume. "I don't think you have a ticket".

Nomu let go of the Pro and went for Izuku. Izuku kicked the Nomu in the face and pushed it off the train.

"Everyone! Stay in your seats and call a paramedic for him"!

Izuku used his grappling hooks to shoot the Nomu away. Izuku shortly followed the monster, recovering his grappling hook.

"Too bad I don't have access to communicate with the Nomu. Feel like I should've gone through that during my first week. Oh well".

Izuku left Nomu in a building and made his way to the roof. "Now, to figure out what's going on".

~Alleyway~

"Bastard! Die!"

"If you can yourself a hero, you should choose your last words carefully".

Stain was holding a Pro Hero against the wall. Before Stain could kill him, however, he heard running footsteps.

"RAGH"!

Stain used his katana to stop an upcoming kick. As he hit his target, their helmet fell off.

"Huh? A child wearing a suit… He's not either one my students, that's for sure. Go away. This place isn't for the lighthearted."

"A scarf as red as blood, carrying blades all over your body… You must be the Hero Killer: Stain! You are, aren't you? I have been chasing you! I am…"

"Your eyes… Are you here for vengeance? Depending on the situation, even children may become my targets."

"Are you saying that I am… not even a target? Then listen, criminal! I am the younger brother of a hero you killed! The younger brother of a most excellent older brother! I have come to stop you in his place! Remember our name for as long as you live! INGENIUM! It is the name of the hero who will defeat you!"

"I see… Die".

~Hosu City (Izuku's Location)~

"It's a villain!"

"Wh… Where are the heroes"?

The Nomu who fought Izuku was ready to attack two innocent civilians.

"Nope".

Izuku kicked the Nomu and landed in front of it. "You two! Get out of here now!"

"R… right"!

The Nomu went for a punch, but Izuku leaped over him and stabbed him.

"Hmm, you don't bleed huh? Doesn't matter. Blood or not, you still feel pain. I ain't gonna let you hurt anyone".

The Nomu let out a terrifying screech and rushed our armored… hero? Before Izuku could retaliate, a huge wave of fire engulfed the creature.

"I was looking for the Hero Killer, but this guy's timing was bad… I do not know who you are, but let the adults handle this."

"Endeavor? And… "

"Why are you here?" "Isn't it obvious? It's because…"

"It's a great way to boost your status from #2 to #1. Stay out of my way. I will actually to try to save them".

With that, Izuku rushed towards the Nomu and got out his weapons. The Nomu however, sent back the flames and went for another attack, but was avoided by the athletic…

"Vigilante… Is he a Vigilante"?

Izuku leaped over the Nomu and used his sword.

"Sorry, Tomura".

Izuku swiftly slashed the Nomu's head, making the creature fall to its knees.

"Game over".

Izuku put his sword back and got ready to escape.

"Endeavor! Stop him! He just killed someone!"

"Close. That thing was already dead. It couldn't think for itself. It would've died anyway."

"W… What?"

"Call it mercy."

"You're still under arrest! I don't care if it's dead or not, but you're not a Pro, are you! You think you can be a strong as us! Vigilantism is illegal. There are two ways this could go. The easy way or the hard way. Please choose the hard way".

Izuku shot a grappling hook and looked at the Pro. "Gonna be kinda hard to catch me. How's that injury?"

"What? How do you…?"

"I'm off. Good luck 'Hero'".

Izuku made his way to the center of Hosu City.

'That Nomu. He was significantly weaker than the one from the U.S.J. Probably a good thing. If they all had the same insane power as All Might then the entire city would be… in danger'?

Izuku stopped himself for a second. "What am I doing"?

Izuku took off his mask and looked deep into the city.

"Who the hell am I"?

Izuku stayed still and tried to think. There was only one thought.

"I have to save them… I have to help them all"!

Izuku ran towards another explosion, not too far from his location.

"What do we have here"?

Izuku saw as different Pro Heroes tried to stop two different Nomus.

"A winged Nomu and another Muscular one. This is gonna be a tough one".

Izuku descended from the buildings and fell on top of the winged Nomu. "Hello. What's your name?"

"REEEEEEEEEEEE"

"Nice".

Izuku grabbed his sword and cut the Nomu's left leg, releasing a hostage. The Nomu screamed in pain and tried to get Izuku of him.

"This is surprisingly entertaining".

Izuku steered the Nomu into a building and used his staff to knock him out. "Manual! Put out the fire!"

"R… Right"!

Izuku got off the Nomu and made his way to the other Heroes. "W… Who are you?"

"For now, an ally."

"You need to get back!"

"Not gonna happen, I'm here to help".

Izuku looked at the third and final Nomu that was causing havoc. The Nomu and another Pro collided fist and caused a huge shockwave. "I need to find Tenya!"

"Tenya?"

"He's a kid who's interning from U.A. He ran off during all the chaos. I don't know where he is!"

"I'll find him later! Right now, we need to keep our focus on these villains! Keep aiming the water at the fire, I'll deal with the Nomu."

"Why is this one so strong?!"

"They're all called 'Nomu'. They are artificial humans and have multiple Quirks. Don't hold back! If you want to survive, then fight with the intent to kill".

The Nomu threw a Pro Hero towards a vehicle.

"The Fly"!

An explosion was seen towards another Pro's location. "Where did he… ?"

"All of you! If you don't think you're up for this, then get the hell out of here"!

Izuku carried The Fly into an alleyway and made his way back to the Nomu.

"I don't know how many Quirks it has, but it seems to have enhanced strength and speed! Who's still gonna fight?"

"I'm not leaving! This is my city!"

"I'll stay."

"We all will".

Izuku smiled under his mask. "Fine. All of you try to distract him, I've already fought two of these things. One had some sort of absorption and release Quirk and the other one had wings. I think this one might have a secret Quirk, as well. I don't want to find out what it is. Ready?"

"Yes!"

"GO"!

Two ninja-like Heroes rushed towards the Nomu and unleashed a barrage of Shurikens behind it. Manual focused his water attack towards the Nomu. Izuku used all of these distractions to his advantage and rushed the Nomu.

"FASTER"!

In the blink of an eye, Izuku reached for his Katana and was on the other side of the Nomu. As Izuku put back his Katana in place, Nomu's arm was completely cut off.

"I was aiming for the head, but I couldn't control my aim".

The Nomu looked back to Izuku as he began growing his arm back.

"You've gotta be fucking kidding me. HE'S ONE OF THOSE REGENERATION TYPES"!

The Nomu ran towards Izuku but was frozen in place. "Ice"?

Izuku looked back to see two newcomers.

"Regeneration, huh? Then, how about this"?!

Endeavor grabbed the Nomu's head and sent a fire so intense, it took the color blue, instead of its natural red or orange. As the Endeavor let go of the creature's head, it no longer moved.

"Carbonized cells cannot regenerate".

Izuku knew what was about to come next, he tried to run away before Endeavor could notice him.

"Going somewhere"?

Izuku felt his legs unable to move.

"No".

Izuku's body became encased in Ice. He saw an Ice trail, followed by Shoto.

"Thanks for helping, but I think you're not a Pro Hero or Vigilante"

"Damn it, Tod… Let me go!"

"Sorry, but… Agh"!

Todoroki was swooped up by the winged Nomu and began to go further up.

"Shoto!"

"Aw Shit".

Endeavor went after the Villain and left Izuku alone with the other Pros.

"Manual! Get me out of here!"

"I can't do that! You're a vigilante!"

"DAMN IT, MANUAL! IF YOU DON'T GET ME OUT OF HERE, THAT NOMU WILL BE TO FAR REACH AND TODOROKI COULD DIE! NOT TO MENTION IIDA"!

Manual looked at Izuku.

"Damn it".

Manual grabbed a piece of debris and began cracking the Ice.

"Someone help me!"

"No need, I just needed you to free my arm".

Izuku pressed grabbed his staff and pressed a button, which shattered the Ice.

"I'll find Iida. I promise".

Izuku used his grappling hooks and followed the Nomu.

"Todoroki"!

Izuku saw the Nomu grabbing Shoto by the throat and flying vertically. Todoroki looked like he was about to pass out.

"SHOTO"!

Izuku shot the Nomu's wings with his grappling hooks. Endeavor felt like he couldn't do anything. After the Sports Festival, his chest and arm may have taken a heavy beating, but his left side of his stomach almost made it impossible for him to sprint. Izuku got closer to the Nomu and Todoroki. Izuku cut off the Nomu's other leg and shoved his staff into the monster's eyes. Todoroki was released and was caught by Izuku.

"Hang on"!

Izuku grabbed both sides of his staff and navigated the Nomu into a building rooftop. "What the hell are you doing?!"

"I told you to hang on for a reason, Icy… Todoroki"!

The three of them crashed and Todoroki hit his head on the building's door. Izuku grabbed his sword and slashed the Nomu's head.

"There we go".

He grabbed the Nomu's body and tossed it off the rooftop. He looked to see if Todoroki was alive.

"Thank god, there's a pulse".

Izuku ripped part of Todoroki's shirt and put it on top of his head to stop some of his bleedings. 'Endeavor should be able to find him here. Now'.

Izuku grappled away and looked into different alleyways. 'Where are you, Iida'?

~Alleyway~

"You know, what's sad. The fact Ingenium would actually try to save someone first. But, you failed to do so. What do you think, Native"?

Iida was on the ground, immobilized from Stain's Quirk.

"It's so rude to not answer my question, you fake".

Stain took out his katana out of a Pro Hero's body.

"You bastard! I'll kill you!"

"There you go again. The only reason I'm keeping you alive is that I know one of my students would be beyond mad at me if I killed some random kid trying to play hero."

"Students? What are you talking about?"

"Me".

Stain looked up to see Izuku knock Stain's katana out of his hands. "What are you…?"

"I needed some air… except that air was filled with blood, fire, and chaos."

"Who are you"?!

Izuku looked down to see Iida. Izuku grabbed Iida by his hair and looked at his eyes.

"Manual told me that you went missing. At first, I thought, 'maybe he went to save someone' or 'he's in danger', but no. Here you are in the ground, claiming to kill someone. Stain is right about me getting pissed killing some kid but wanna know what gets me more pissed. A person using their Quirk for selfish ways. Just so you know, Stain isn't the one who killed your brother".

Iida's eyes widened as Izuku got closer to his ear.

"I did".

Izuku let go of Iida and gave Stain his sword back.

"Let's go. Your other student might be wondering where we are."

"Right".

Izuku grabbed Iida's phone and sent his location to Manual, along with a message to call the paramedics. Both of them made their way to the hideout.

"Y… you killed my brother! I'll kill you! I WILL FUCKING KILL YOU, DAMN IT"!

Izuku stopped in his tracks and looked back at Iida. "What are you doing?"

"I find him unworthy".

Izuku started walking towards Iida and Stain looked at him. "Don't you dare"!

Izuku ignored his master and looked at Iida. he pointed at him and spoke.

"Unworthy."

"Unworthy? Unworthy of what"?!

Izuku grabbed his sword and began scaring Iida. "Your Quirk."

"DON'T YOU DARE!"

"My… Quirk… Wait! No! Please… AGHHHH"!

~Alleyway (1 hour later)~

Manual and other Pro Heroes made their way to the location that was sent. "Iida! Iida"!

Manual finally arrived at the location but fell to his knees. "I… Iida"?

~Stain's hideout~

"I'm gonna ask you one last time… What the hell have you done, Midoriya"?
