Hi, hi, hi! This it he first crossover I've ever posted and my first time dipping my toes into BNHA fandom. So, new audience and my One Piece audience, it's mostly two OP characters in the BNHA world. There are probably some things not correct in here, but nothing major. It follows the story line but changes it up quite a bit. There is blood in this, more than cannon typical, but I'll change it to M if anyone wants me to when we get to that part.

No manga spoilers, I am proud to say, even though the plot of this goes on after Hawks (my beloved) is introduced in the anime, last episode of season 4. I don't know what to expect attention wise on this one as I've never posted a crossover, so I guess we'll just have to wait and see. Canon-divergent just to be safe. Anyways, I hope you enjoy. It's a long one!

Edit: Dear Wickerstein, please don't review on this story. Thank you.


"C'mon, we promise we'll treat you well. You'll be happy with us," a villain who could create chains said in a sweet voice as it chased the two twelve year olds around the street. They'd seen Ace and Luffy create a light in the alleyway when it was dark, controlling their powers perfectly together, Ace lighting a blast of fire and Luffy containing it into a compressed ball to give off light.

"No!" Luffy shouted, holding his twin's hand as they ran. They shoved past normal people, trying to find somewhere safe to hide. This area was one of the areas that rarely had heroes. It was a sad fact that heroes didn't care about the people here.

The homeless kids had no money for food, so they always went to the crowded homeless shelter instead of stealing. They'd probably steal right when a hero would show up, based on their luck. But they wouldn't attract the villains there. They wanted to be heroes, so they wouldn't commit crimes. And they couldn't fight back with their quirks or they'd get introube if they were caught.

Both wanted to be heroes, but as partners. They helped one another with their quirks. Ace could control and turn into flames, while Luffy could manipulate air in any way. They had small weaknesses. Ace ran out of fire if he kept himself in flame form for more than five minutes and needed ten to regain his strength.

Luffy's weakness was that it was more taxing for him to aim air in a pointed line, always a big gust.

"C'mon! Be good little boys and join us!" the villain shouted, shoving people out of the way as he threw chains at the boys. They were running as fast as they could, and were able to slip through crowds more as they were younger and skinny. Both twelve.

They were fraternal twins except for their hair color and different colored eyes. Finally a chain came so close to them that it nicked Luffy's cheek, cutting him and making blood drip down. Finally, they saw a hero. It was unusual for them to be here, but they needed help.

Both homeless boys ran up to him and grabbed his clothes. "Help us!" Luffy begged. It was a guy with a stone mask on. "Please, they're after us, always after us!" He put his hand on their heads and vowed to help them, asking what the problem was.

Ace pointed behind them and said there were villains, ones that could create chains and another that was able to create anything made out of paper. "Alright, stay here, I'll be back for you two," he said and hurried off, only the villains just arrived and he didn't even use a quirk, just taking them down with fighting hand to hand.

The two kept track of him easily with their abnormally good senses. They could tell who was around them, what was moving. Even where there was no sound or sight, they knew where anyone was. That's why they were able to escape normal criminals. Villains were harder, especially when they were fast.

Ace and Luffy weren't fast, as they were skinny and weak. Soon, the villains were in cuffs, and a police van was taking them away. The hero walked up to them and crouched. "What are your names?" They gave him their names, though only their first names. They didn't have a last one that they knew of. They were dumped on the street as young kids.

Their parents didn't like how they were stronger than they were even as small children. They'd never been to a school or knew how to read or write. They were street rats, always hiding from villians, trying to hide their abilities as best as they could. It was difficult not to, though.

"My name is Gunhead. Why were the villains after you?" he asked kindly.

Ace said, "Our quirks," simply. "They're always after us, always know." Gunhead asked if they were homeless, which was pretty obvious by their clothes. They nodded, both looking ashamed. He asked how long they'd been on their own. "Five years, I think. It's hard to remember sometimes." Gunhead sighed behind his mask.

"How about I get you safe somewhere? A nice place where you can be clean and cared for," Gunhead said, sounding so kind. Luffy had tears in his eyes and both boys nodded. After the villains were taken care of and another hero had come to search for anymore that might be hiding, they left. "So, what are your quirks? That has caused you so much trouble?" Gunhead asked. He was a hero, they would tell him honestly.

Ace said he'd show and lit his hand on, white flames showing up. Luffy lifted his hand and air encapsulated the fire, making it into a ball of bright light. It dissipated after Luffy stopped his power. Ace said, "We work together with our powers a lot. Then there's the other one that doesn't make sense."

They could see Gunhead's reaction from his mask. "That is impressive control. How old are you two?" Luffy said they were twelve. They were asked if they had any training or they figured it out themselves.

Ace replied, "We figured it out ourselves. Our parents didn't like our quirks because they were stronger than their own. They dumped us when we were seven." Gunhead's head dropped a bit and he asked for confirmation that they'd been on the street for five years. Ace nodded, and said, "There was nowhere to go. Heroes never go to that part, so we were on our own."

Gunhead apologized. He wasn't the one driving, and was sitting in the back with them. He promised that heroes would start patrolling there. That nobody should be forgotten. Even though they were leaving there and not going back, making sure nobody went through what they did made them both happy.

Then the hero remembered something Ace just said. "You have another power? There's never been anyone with more than one quirk." He sounded curious and confused. Luffy explained it this time.

"We both have like, a sixth sense. We can tell where people are, see what they'll do next for a couple seconds. It's weird. We're not seeing or hearing them, we just feel their presence and know where to go for safety. That's how we haven't been caught yet. We're usually good at escaping before anything bad happens," Luffy said honestly.

Ace nodded, and added that they didn't know where it came from or why they had it. But it was useful and helped them a lot. Gunhead asked if they used it for anything else. They shook their heads. Ace said, "Well, if we get in fights with the other kids, we can't use our powers so we usually fight physically, even if all of us are skinny and starved. We can avoid their punches or kicks."

Luffy proudly said that they always won. Gunhead was quiet for a moment. "How would you two like staying with me? I can help you with your quirks and take advantage of the extra sense. You can stay with me." Ace and Luffy looked at each other before nodding with watery smiles and loud "thank you"s.

"Consider it as also an apology, for putting you through that life. For us heroes not being there for you all," Gunhead said in a sad voice. They both said they forgave him. They both had somewhere safe to stay, with someone who seemed kind. Weren't most heroes good people? They wanted to be heroes too, so maybe staying with one would be helpful!

-x-

"This is all for us?" Ace asked in shock at the food in front of them. It was just soup and bread. Not much, but to what they usually had, this was a feast. Gunhead nodded, saying once their stomachs got used to food again, they would be able to eat much more.

"Make sure you eat slowly or you may vomit," he warned. They couldn't see his face still, but he sounded like he had a smile on. He sat at the table, which was small in his home connected to his dojo where he taught people how to fight without their quirks. He then asked, "How would you two like going to school?"

Ace and Luffy looked at each other and then back to the nice hero. "But we don't know anything. We'd have to start in elementary school," Ace said in an angry voice. They both wished they'd gotten an education like normal kids did. They were lucky, made friends and got to learn new things.

Gunhead said, "Not necessarily. If we cram, you would realistically be able to attend junior high for the last half of the year. It would be good training for high school. It would be a lot of work, but I think it would be worth it. And you could train even more with your quirks. After being with me, I'm sure you guys will be even more talented."

"Yeah! We want to be normal kids," Luffy cheered. Ace nodded vigorously. Gunhead said that was great, and they'd start in three days. Once they were a bit more used to life in what they saw as luxury. They had a small room to stay in that had always held equipment. They shared a bed, a big one, so there was room for a dresser.

Gunhead asked them if they were twins. Ace nodded and said they were fraternal, but had the same eyes. "They're very pretty eyes. I haven't seen ones like yours," he said. They both looked down and Luffy told him they were always mocked for them. "You have to be strong to be heroes. There's no reason to hate yourself just because someone else might."

They both smiled, and ate their food before going to their new room. Gunhead had called ahead of time for his assistant to buy a large mattress. They were also washed and not dressed in rags. They held hands in nervousness as they looked in the room. Luffy approached the bed and slowly climbed on.

Ace got on after him, they kept the door opened just a crack. Anyone outside the door could hear their sniffles. They fell asleep easily, cozy under the blankets. They'd shared close spaces long enough to not want to be separated. At least, not yet. When they woke up, both of them were crying again, having thought the day before was a nice dream. Until they woke up, where it would have been terrible. Thinking they were somewhere nice only to wake up in their cardboard box.

They ate applesauce and other soft foods like sandwich bread. Any food was beautiful and perfect to them. They wouldn't be greedy kids. They'd had nothing for years, and now they were given food and shelter. Also with the privilege of new clothes and a bathroom with a shower!

The next day was wonderful, and Gunhead asked if they could show him their sixth sense. Luffy encouraged Ace to do it, while Luffy sat on the wood floor. It was amazing, wood floor. So smooth even though it was made of wood. He was wearing socks. Shoes weren't allowed in the dojo.

Ace closed his eyes and put mufflers on to show it more clearly, that he didn't have great hearing. When Gunhead stuck his hand out, Ace sensed it and easily moved. Gunhead did this over and over, and when he swiped to Ace's head, he ducked, the swipe going right over his head. Once Ace felt Gunhead stop moving, he opened his eyes and took the mufflers off.

"And Luffy can do that, too?" The younger twin nodded. "That's incredible. You two can become so strong. And you want to be heroes?" They both nodded. "Then you have a head start with your skill with your powers and this sixth sense."

Luffy frowned, and asked if heroes could come in pairs, since their powers work well together. "There are many duos in the hero community. I see no reason you could not be a pair. Many heroes are married to their hero partner. Close relationships help teamwork usually. Teamwork is very important to be a pro-hero."

They both grinned at each other. After that, the boys sat in front of a TV in the back room. Gunhead wasn't going to make them do anything strenuous until they had put on more weight. Ace said quietly, "Are you excited for school?" Luffy nodded, but added that he was nervous that people would find out they'd been homeless. "Then we'll just not say anything. The only people who know are us and Gunhead," the freckled twin pointed out." Luffy nodded, and leaned against Ace's shoulder.

He was the taller twin of them, though they were close in height. They also looked forward to learning new things, like math and reading and writing. Gunhead hired a tutor for them. "Gunhead is nice. I like him," Luffy said. Ace nodded in agreement as they watched the news. They never knew what was going on with the rest of the area, country or world. Cut off from everything.

They wondered what their parents would think, if they became pro-heroes. Would they regret throwing them out or be even angrier? Having them be pissed would be better, that after they deserted them, they were now living with a pro-hero. Hopefully he didn't change his mind and kick them out. The day was spent playing games while Gunhead taught his classes in the dojo. They learned how to play checkers by diagrams and not words. Chess was impossible to play, and so were cards. It was frustrating, but they would work very hard on their studies.

What was high school like? They didn't know where it would go or how it'd work. What kind of things did they learn there? They were positive they'd make it to high school even if they didn't reach junior high in time.

-x-

When the tutor time started, they first learned basic math, which was easy and logical. They paid very close attention and asked questions easily, not hesitating to do so. The tutor said that they were good students to ask questions. She taught them how a normal school would. Six hours a day with small breaks between topics.

After math came reading. They couldn't write until they could read. It was harder than math, but Ace was able to easily remember the letters in the alphabet while Luffy had to look back at the reference more. They mostly learned those things, no history or science yet. They'd learn basic science that might be needed.

Gunhead had already been talking about high school, and a specific one that they said great heroes came from. U.A. They didn't care where as long as they got education and training, but after looking at photos of it online, it was huge and so cool. So, because the campus was amazing!

But they wanted to at least spend some time in junior high to get used to how it worked and what it was like with others besides themselves. In a big setting, a classroom, they wondered how it was.

Even when they were little, they weren't allowed to go to school. Their parents only wanted them to learn their quirks, but once they realized they were stronger, they were thrown out and were then unable to go to school for obvious reasons. The only thing they'd learned from living on the streets was how to get away and stay safe. Nothing else.

Every day, after their sessions, they were given tons of homework which they completed together, helping one another out. Ace was the smarter one, so he helped Luffy while they worked. And when they weren't working and were finally at healthy weighst, Gunhead started to train them in physical fights, not their quirks yet.

He taught them the very basics at first, like how he taught his new classes. But having one every day for over two hours easily put them ahead from the two times a week classes Gunhead gave every day. He spent the evenings mostly helping the kids he'd been taking care of.

They still hadn't seen his face once, and hadn't asked. It wasn't their business, even if they were curious. He seemed like he wouldn't dump them, and wanted to keep his word in taking care of them. Sometimes they felt like they didn't deserve it, mostly Ace. That they were a burden, taking up his time and money.

Luffy tried to convince him that Gunhead did like them, that he wasn't faking. They were sure he'd heard that conversation when the day later he gave them gifts. They were in small boxes, and he saw they were wristbands that said their name and then the name of Gunheads agency.

"You're always welcome here to stay for good or until you're ready to leave. I'm not going to do what your parents did," he said firmly. Ace didn't ask if he'd overheard, because it was pretty clear. Well, they kept their bedroom door open a crack at all times. It wasn't so strange that he'd heard them.

Every Friday night, they had a huge feast to celebrate their effort in both their studies and training sessions. He was teaching them as best as he could to not only rely on that sixth sense. Apparently, there was no record of anybody achieving that kind of ability. So they felt special, not weird. It was cool to have that power.

Gunhead said it gave them an advantage, but they should also learn without it. So they did. Their days were spent with class, homework, fighting lessons, and then watching TV or playing games. They knew numbers now, so they could play with cards.

When Gunhead had asked them why they watched the news instead of something more entertaining, Luffy gave their reason. "We've been cut off from everything for so long, we don't want that to happen again."

Sometimes it seemed like Gunhead had forgotten how they lived before. Like when he seemed surprised when one of them would mention how they hadn't had something in their old life, or mentioning any aspect of it. Maybe it was because they'd adjusted to this new normal fairly quickly.

They were quick at adjusting to situations because of the every present knowledge that things could change at any time. It had been necessary on the street. But there was a problem that was found when a kid their age came for his lesson. They had hid from him immediately.

Ace was sure it was a left over feeling from having to fight off or compete with other kids for food or territory. Well, it was better than challenging them to a fight immediately. That wouldn't be good. When Gunhead asked them why they hid, Ace replied, "We're kind of used to fighting other kids over food and territory. They used their quirks on us while we didn't.

"We didn't want to get in trouble with the law," he said simply. Luffy nodded along, and also said that they hid from them if they got food, so they could eat it without them seeing.

"Well, to go to school, you'll have to be able to be near a lot of other students," the hero pointed out at dinner. Ace and Luffy looked sad. They both said they'd do their best, and asked if they could take part in the group lessons if there were other kids their age. Still twelve, turing thirteen on New Years.

"That's perfectly fine. I think that's a good idea," Gunhead said. Even when he ate, he kept the mask on, only lifting the bottom up to eat. They went to bed that night nervous, but determined, sharing decisive nods about the next day. After their lessons, they'd take part in the later session with the two other teenagers.

They were nervous all day, though they didn't let it interfere with their work. "Ace, you didn't need to go through the whole book," Tina, their tutor, said. Ace had finished the entire math book he was given. Luffy had written a short story. They both went overboard with studying and working ahead.

The two didn't get in trouble for working ahead, and the tutor even praised them for it. Luffy's story was ripe with spelling and punctuation errors, but considering they'd only started three weeks ago, it was a wonderful improvement. "And it looks like you two aren't sharing answers. That's very mature and responsible."

Luffy grinned and said, "Cheating in anything is wrong. Plus, we both want to be smart on our own." Ace saw Gunhead in the doorway watching with his arms crossed and back straight. Since they couldn't see expressions, they'd learned about telling body language from a program on TV, since they couldn't read very well with more complex wording.

But his body language was one of pride. In them. Ace smiled softly and turned back. "While you worked ahead, there are still errors. I'd like you to go through those ones a second time after today, where we'll have a review on what we've learned so far.

After class, they got changed into their work out clothes, and waited in the corner for the two teens to arrive. They did, both in exercise clothes like Ace and Luffy's. It was ten minutes before class started that they finally talked to kids that they didn't think would hurt them.

"My name is Toyaka," the blonde one said, and they shook hands. The other was Tami, a girl. They shook hands with her as well, and introduced themselves. Their eyes were very noticeable, and they were asked if they were related.

"We're twins," Ace replied. Luffy was smiling, feeling they'd made friends already.

Tami lamented not having an identical twin so they could play pranks on their family and friends. Ace and Luffy smiled, thinking that was funny. "So did you join late? I thought new classes weren't being accepted anymore. Contracts had already been finished."

Luffy spoke honestly, "We stay here with Gunhead, now. We've been here a couple weeks." They looked surprised and Tami asked why they stayed with him. But Toyaka said it wasn't her business, and she apologized for being nosy. "It's fine, I'd be curious, too, though it's pretty personal."

Ace nodded, saying, "We're not upset with your question, don't worry." They bowed when the class started, and worked on basic moves that Ace and Luffy had already mastered after weeks of non-stop training. They enjoyed it, though. They could see himself getting stronger, mentally, physically and appearance wise. Both of them were toned and more healthy than they thought they'd ever be.

After the training was done, the four parted, and Ace and Luffy said they looked forward to seeing them again. "You guys, too. Have a nice day," Tami said with a grin, waving. Once the door closed, Luffy and Ace gave each other high fives.

"You two did very well," Gunhead praised. They grinned and thanked him. "And pretended well that you didn't already know these moves."

"It was easy!" Luffy said happily. "We made friends," he said proudly. Ace crossed his arms and looked proud as well. As of now, nobody knew of their presence with Gunhead. Nobody knew he had kept them, so that nobody thought it was unfair once they started school. That they had training personally already.

At dinner, Luffy said, "I don't want anybody to know my quirk when we go to school. I want to make friends for me, not my quirk." Ace nodded, saying that he agreed that that would be the best course of action. "Besides, we'll be strong enough from our training here."

Gunhead replied, saying that was noble. "You're right, many are friends because of their quirks and not who they are. Wanting real friends is something many don't care about, they want to be popular. I'm sure you'll make better friends without everybody knowing."

Both boys nodded. Gunhead asked how their homework was going, since they were getting more, to their own requests. They were both dedicated to be normal kids as soon as possible, leaving their old life behind in the dust as quickly as they could. Wanting to get away from that time. They stopped talking about then. More focused on the future and not the past. Their futures looked much brighter than their past, since the present was already great.

Luffy said, "I'm almost done, I have to finish the packet on photosynthesis. I needed a break." Ace said that he was almost done as well, but had to finish the essay they'd been given. They helped one another out, but worked on different parts, not going at the same places at the same time.

Gunhead whistled. "You asked for all that homework yesterday morning," he pointed out. "You two already make great students," he complimented. Ace laughed and said they were proud nerds. Gunhead chuckled. "And I'm sure you'll make many friends."

Ace and Luffy blushed a little bit, saying they hoped he was right. Gunhead was absent much of the night as he worked as being a hero at night now that he had two kids to look after, even if they could look after themselves fine. But they didn't want to be alone all day. So he was there in the morning. He was able to function perfectly on five hours of sleep.

The brothers, though they'd been in a new life for over two months, had not separated much. They were always in the same room, even if they weren't doing the same thing. They held hands while sleeping on the same bed. They grew stressed out when one was sick, when Luffy caught a cold from the tutor.

They'd been through so much, only having one another, that it was hard to be apart. Nobody tried to force them. They weren't ready and the tutor or Gunhead weren't going to rush them. Once they were more comfortable apart, maybe they'd try giving them two twin beds instead of one queen.
