TheAverageJoeIsMe: Fun fact this story started as a one-shot on AO3. I just wanted to write a short piece about how Spider-Man would react to finding Eri in that alleyway. Originally Peter just completely replaced Izuku in the story, so he was Nighteye's intern and Mirio was with him. But then I decided to make him a vigilante just to make things different and more interesting. So I didn't have a big plan for where the story would go from the start. But I ended up liking the one-shot so much, I decided to make it a full story. Which brings us here.

supersandy220: Overhaul noticed that all the pictures of Spider-Man were taken by Peter Parker. Peter is always credited for his photos in the Daily Bugle and other people have used it to make a connection between Peter and Spider-Man

RunOnSentences: Yes, however Overhaul is evil and wouldn't hesitate to jump on any lead he could find, regardless if it ended up being wrong and they killed some innocent guy.

DarkBeast42: I appreciate that. Thank You.

PEJP BengtZone V2: Eri has been dissected so many times, so Peter wouldn't want to do anything to hurt her. Also Peter doesn't know Class-1A well enough to do that. It would also be next to impossible, due to them living in the dorms at U.A. Lastly I can neither confirm or deny who will or won't be showing up in the future.

Okay, since a lot of people are still asking about why Peter is in Japan, I'll break it down for you all in more detail.

The MHA version of Japan is very diverse, just look at Aoyama. So imagine this, when quirks first began to emerge all the countries under the United Nations were forced to work together to deal with the situation. As a result of this corporation and the havoc and chaos caused by quirks, many families were either forced or chosed to immigrate to other countries. This includes Peter Parker's quirkless ancestors from America. Let me be clear, when I mean ancestors, I mean Peter relatives from several generations back. So Peter was born in Japan, Aunt May was born in Japan, Aunt May's Grandparents were born in Japan, etc. However they are of American descent, which is why they have American names. Assume this applies to all the Marvel Characters in this story, unless stated otherwise. I hope this is a good enough explanation to you.

Parker Residence,

"Hey Foggy, I've emailed you and Matt a list of equipment and supplies Overhaul would need to produce his drug, it's not much but I think it could help" Peter said over the phone.

"Thanks, I'll check any delivery records and I see if I can find anything useful," said Foggy.

"Right, talk to you later," Peter hung up the phone and put on his backpack.

"Where are you going?" asked Eri.

"I have to go to school, I've already missed a day because of well...y'know," answered Peter as he put on his shoes, "I won't be home for a little while, but Aunt May has taken the day off to stay with you."

"Okay, have fun," Eri waved goodbye.

"See ya later," Peter waved back, exiting his house and made his way to school.

'Eri seems a lot more cheriful ever since we've had that talk yesterday,' Peter thought as he walked down the street, 'That's good. She's still young, if we're lucky we can maybe heal a lot of the psychological damage done to her. Speaking of which she still should go to therapy. I wonder if we can afford that…"

'...She also needs to learn how to control her powers, but she's too scared to even attempt it,' Peter sighed, 'I can relate. There's always been a part of me that's afraid of my abilities, afterall my quirk isn't even a quirk at all...'

Peter closed his eyes and tapped his forehead, 'There's also still Overhaul to deal with. Eri will never truly be safe until he's behind bars. But we still don't have any solid leads. And with the pros always on constant lookout for me, it makes everything more difficult.'

Peter shook his head, 'We're running out of options. Y'know what I'm actually excited for school today, I could use some normality in my life right. I can worry about Overhaul once it's over.'

Peter walked down the halls of his high-school. Everyone was chattering about the news about Spider-Man. It was a big deal, since his other identity had become something of an icon at his school.

"Did you hear about Spider-Man?"

"Yeah, I heard he fought one of the kids from the U.A. Sports festival!"

"Was it the dreamy one with the ice and fire?"

"Nah, I hear it was the guy who kept breaking his fingers"

"Who cares about the guy he fought, he straight up kidnapped a child!"

"Yeah, I hope they find her soon..."

Among all the murmurs, one person was particularly passionate about the subject.

"I'm telling you guys, Spider-Man was set up!" Flash Thompson, member of their high-school football team and Peter's lifelong bully yelled, "There's no way he'd ever do something like that."

"Ha! You're just upset that your precious hero turned out to be nothing more than a big phony," laughed Sally Avril, cheerleader for the team, "That's what you get for worshipping a vigilante."

"Arrrggghhh," Flash growled before noticing Peter, "Hey Puny Parker back me up! You believe Spider-Man's innocent, right?!"

"I don't want to be a part of this," Peter waved his hands defensively.

"See even Parker thinks he's guilty," said Sally, "And he makes a living off the guy!"

"Hmph I'd thought you of all people would have his back. Whatever you'll see," Flash stormed off, shoving Peter in the process.

"Sorry about him," Rand Robertson, another player on the football team apologised, "This whole thing about Spider-Man has got him worked up."

"Y-Yeah, I get it..." Peter said solemnly, thinking about what Flash said.

Peter checked his phone as he walked back home from school. He'd had a lot of missed calls from Jonah.

"I'd bet he'd love to have pictures of Spider-Man right now. Probably give me a huge check," Peter sighed, "Too bad I didn't take any-"

Then Peter heard an all too familiar sound, police sirens. Coming from the direction of his home.

"No no no no! Not again!" Peter ran full speed towards his home, "This can't be happening again!"

A Little Over a 1 Year ago,

...And, one evening as Peter Parker returns home from a personal appearance…

"A police car! In front of our house! What can be wrong?"

"Bad News Son-Your Uncle has been shot-Murdered!"

"Uncle Ben-Dead! No! No, it can't be!"

"Who did it? Who shot him?"

"It was a villain-You're Uncle surprised him! But don't worry lad! The Pros got him trapped! He's in the old ACME warehouse at the waterfront! They'll get him! You're Aunt is next door-The neighbors are looking after her! Wait-"

"I've got to go! I've got to get him!"

"I know the old ACME warehouse! It's been deserted for years! A villain could hold off an army in that gloomy, old place! But he won't hold off-Spider-Man!"

Present Day,

Peter arrived on the scene to see his house in ruins. There was a giant hole in the front entrance and rubble all over the front lawn. It was like a bulldozer ran through his house. Peter could care less about the condition of the house, he was more concerned about the people supposed to be in it. Peter ran over to one of the many police officers surrounding his house.

"What happened here?! Where's my aunt and my sister!" Peter demanded.

"Calm down son," said the officer, "Do you live here?"

"Yes, my name is Peter Parker," Peter answered, "Now where's my family?! Are they hurt?!"

"There was a villain attack on your house, but we currently don't know where your family is," the officer answered.

"What do you mean, you don't know?!" Peter questioned.

"There's no signs anyone was injured. So we believe they either were taken by the villains who did this, or they weren't home when the attack happened," the officer explained, "We have our boys checking the street cameras as we speak to confirm."

"..." Peter processed the information given to him.

"Don't worry son," the officer consoled, "Wherever they are, either us or the pros will find them"

*Bzzzt, Bzzzt

'Ah, my phone!' Peter pulled out his phone, checking the caller ID, 'It's Aunt May, she's alright!'

"Aunt May where are you-"

"Is this Peter Parker?" that sinister voice was unmistakable, he was talking to Kai Chisaki, Overhaul, "I'll take that silence as a yes."

"Where are they," Peter demanded.

"Getting straight to the point, huh? I must say, when I sent my men after your Aunt I wasn't expecting we'd find Eri there as well. Now I'm not sure whether you're actually Spider-Man or just one of his associates, you are seemingly quirkless after all. But since you seem close enough, I need you to pass along a message..."

"..."

"...Eri belongs to me. And if you don't want your Aunt to end up like your Uncle, you'll tell Spider-man to stay away until I'm ready to cure him of his disease and put him of his misery. When that time comes I'll contact you. Goodbye."

Peter hung up the phone, clenching his fist. His worst fears had been realised. A villain had figured out his identity and taken his Aunt, his last remaining family hostage. Furthermore Overhaul had taken Eri and was doing who knows what to her.

'Dammit, I'd let it happen again…,' Once again he'd let the people closest to him get hurt, and worst of all he had no real leads to find them, 'I'm sorry Uncle Ben, Aunt May, Eri...'

"I-I'd like to stay with Spider-Man," said Eri looking up at the masked man.

"Nice to meet you Peter," Eri smiled.

"Thank you -Man," Eric mumbled.

"P-Please, please don't go," she sobbed quietly

'No! This isn't over yet!' Peter began to run away from the scene of the crime, 'I'll get them back! I promise I'll save you Eri!'

Peter ran into a back alley ripping off his shirt to reveal his Spider-Man costume underneath. Pulling his mask over his face, he leaped into the air. Swinging towards his destination. There was one last lead he had left, one option he had refused to accept, one person who might know where Overhaul's base was located. But getting that information wouldn't be easy, but he'd do whatever it takes, even if he didn't like it.

Shie Hassaikai Underground Base,

"...When that time comes I'll contact you. Goodbye," Overhaul hung up the phone.

"Boss we hooked the old lady to one of the beds in the medical ward like you asked," said Mimic, "We pumped her full of anesthesia. She won't wake up, unless we want her to."

"I'm sorry boss, but isn't it risky to keep Spider-Man alive?" asked Chronostasis, "Shouldn't we kill him as soon as possible?"

"Maybe, but finishing the product is our top priority and we can't risk dealing with him until it's finished," Overhaul explained, "Until then, distractions can wait. Now leave, I want some alone time."

"Of course, right away boss," both men left the room.

"P-Please don't hurt them!" Eri, who was tied down to a surgical table, yelled out with tears in her eyes.

"I won't hurt them, for now at least. After all we're behind schedule and you need to be punished..." said Overhaul, "But once we're done. They're dead."

"N-No!'

"Remember Eri, this is your fault," Overhaul explained, "If you hadn't run away, they wouldn't have to die."

"..."

"Now let's get started, we've got a lot of time to make up for." Overhaul reached towards Eri's face. Eri clenched her eyes shut, before everything went dark.

Fisk Tower, Downtown Tokyo,

Spider-Man landed on the tall tower. He looked around for an entrance to the building, before deciding to go through a ventilation shaft.

Peter didn't want to do this. He didn't want to ask him for help, but he didn't have a choice: every second he wasted was another second Eri was alone with Overhaul.

Spider-Man crawled through the vents until he reached the room he was looking for. The room was a large very fancy looking office with several art pieces decorating the room. And sitting at the large desk in the room was Wilison Fisk, the Kingpin of Crime filling out some paperwork. Spider-Man jumped down from the vent and landed in front of the Kingpin's desk.

"Hello Spider-Man, I've been expecting you to show up sooner or later," said Kingpin, not even bothering to look in his direction.

"Fisk, I need to know where Overhaul's base is," Spider-Man demanded.

"Oh, no fat jokes this time?" said Kingpin, "Perhaps you're maturing after all."

"I'm not playing around this time Fisk!" Spider-Man growled, "I know you know where he operates. His new miracle drug is going to cause the Shie Hassaikai to gain a lot of power and influence among the villains and other gangs, which can't be good for your business. So tell me where he is!"

"...Alright, I'll tell you," Kingpin said calmly.

The anger flushed out of Peter instantly, "Really? I'd thought you'd put up more of a fight."

"Hmph, it's like you said 's new drug is problematic for me," Kingpin explained, "...And despite what you think of me, I don't like seeing an innocent child suffer."

"..."

"I must warn you though, it seems the Shie Hassaikai has created an alliance with the League of Villains," said Kingpin.

"Oh Great, those loonies," Spider-Man sighed.

Kingpin scribbled down some information onto a piece of paper and handed it to Spider-Man, "This is all the information you'll need. I'm sure you can see yourself out now."

"Thanks for the tip, but don't think this means I'm on your side now," Spider-Man, "The second this is over I'm going after you."

Kingpin simply gestured to the door, resuming his paperwork without a care. Spider-Man exited the room the same way he came. Once he'd exited the building, he took off swinging. He'd finally had a lead on Overhaul's whereabouts. Now he needed a plan.

Spider-Man pulled out his phone mid swing, dialing a number, "Hey Horn Head, I've got a lead."

Outside the Chie Hassaikai Base,

Two average looking men stood outside the building presumsely where Eri and May were being held hostage. From an outside perspective this place looked like any other business office. But these men with their extraordinary senses could tell there were sinister things going on in that place.

"You pick up anything?" Peter asked his blind friend, "Spider-Sense is warning me of danger coming from underneath this place."

"Yeah, I am," Matt nodded, "Looks like your information was correct."

"Hmph, I guess the fat man has a heart after all," Peter shrugged.

"Now to find the entrance...," Matt used his Radar Sense to survey all the people inside the building, waiting for someone to enter the underground base. Then it happened, one of the goons inside lifted up a vase, pressing a button and opening a secret passageway leading underground.

"I found it," said Matt, "I know how to get inside."

Peter smirked, "Found you."

Big thanks to Cylon One for helping me out and checking my grammar and spelling on the last two chapters. I really appreciate it.
