(What)Guest & (Why)Guest: I've already answered you question for you. I'm not going to say the same thing 4 times. There's no point in complaining about the contents of my stories because they have been finished and ready to post for over 7 months and I will not be changing anything about them. If you don't like how my stories are written, then you're not forced to read them. Plus you told me you were going to drop it, and then 6 hours later you repeated the complaints. No more replies will be written anymore.


Hello, readers! I will be post-dumping now. All remaining chapters will be posted today. I don't enjoy posting crossovers on here anymore. It's just not rewarding. But I won't ditch a story, ever, so I will post every chapter and just be done with it. If you'd like to read any of my future crossovers, they'll be posted over on ao3 under the same username. And the chapters will still be staggered on ao3 if you'd like to wait for the weekly updates (lol though I don't know why anyone would willingly wait). I won't be responding to reviews anymore, either, since I'll be posting all at once.

I hope enjoyed my story. It was a super fun one to write! And if you dislike my story, please just move on. Thanks!


Then they sadly returned to school. It felt like it was weeks ago, the last time they slept in their bed. That time felt like a lifetime away. When they went inside the dorm, everyone was waiting for them. "You're all back! We were so worried!" Ashido exclaimed. Ace's hand went to his gloved arm unconsciously.

"Let's not talk about it," Luffy said with a smile. They were shocked and confused, but they nodded. They awkwardly went to their own things, leaving Ace and Luffy to head to the others, ask them what had happened. The story was the same for all of them, and it made Ace and Luffy happy.

"If I hadn't known about their quirks or their pasts, I would have had a much harder time." Kirishima the most. Ace and Luffy felt so happy about that, it made Ace smile. They asked about Eri, and were all so happy that they were able to save her.

Luffy replied, "Eri is sweet, but she's going to be emotionally unstable for a while, if not forever. We're asking permission to go see her for a bit while hero work studies are paused." Kirishima finally asked the big question. How the fight with Chisaki went.

There was something wrong with them. Something wrong with Ace and Luffy. Why were they open about traumatizing stuff? Why did they do that? It wasn't meant for other people to know, yet they did. Why did Ace take off his glove and show the mark. Was it because Luffy was brave and strong enough to share the memories of his torture that he had to as well?

"I killed him. It was an accident. His power seemed to activate the moment it made contact with someone. So I tried that idea Luffy had thought up. It would have worked perfectly if I aimed right. I should have moved his hand downwards, not upwards. It didn't hit his leg, but his chest, blowing his upper body all over the walls, floor and me. I was covered in blood. And now I have this mark that no one knows will go away to remind me of that." He smiled weakly. "An improvement, I didn't throw up talking about it."

Luffy took Ace's hand, and the older twin put the glove back on. "We're gonna try to get a nice sleeve to go over it for now. The mission was a complete success, we defeated everyone, saved Eri. But this happened, so it wasn't that great of an achievement. Y'know? Just wish it could've' ended a bit differently," Luffy said.

Uraraka had her hands over her mouth. "I'm so sorry, Ace." Ace thanked her, asking them not to spread it around. At least not yet. It wasn't something that happened to him, like Luffy's torture. It was him doing something unforgivable, even if he knew most would agree that it wasn't his fault and he shouldn't be punished for it.

It was very hard for Ace to sleep that night, so Luffy snuggled him. It would look really weird to anyone else, but Luffy hugged Ace all night, and it worked and he didn't wake up from nightmares. When he woke up, Ace discovered that there was a puddle of drool on his ear.

"Seriously, Luffy?" he asked, wiping the drool off with Luffy's sleeve. He sat up and looked at Ace, but didn't call him a watermelon this time. He poked to his own cheeks.

"Rotted skin," he mumbled.

"You have to be joking or I'm going to throw you off the balcony." Luffy burst into laughter, and Ace joined in. It was a nice light mood, and classes started again the day after. They were going to see if they could see Eri. After they ate, they called the hospital, those who had gone to fight for her in the room. They were all still exhausted emotionally if not physically from the whole mission. It was stressful, but Eri would be having the hardest time right now.

"Hello?"

"Hi, this is Luffy, we rescued Eri the other day and brought her in. How is she doing? Can we talk to her?" the youngest twin asked.

"Her fever is down, but she's very scared and confused. Her quirk is making it a bit difficult for us. But I'll see if she wants to speak on the phone with you." After a moment, they heard beeping and footsteps before Eri was told when he was on the phone.

Her small voice asked, "Luffy?"

Luffy and Ace grinned. "Hi, Eri. How are you feeling?"

She sniffled. "I'm scared. And I can't be around anyone. I keep hav-having bad dreams." Her voice was scared and unsure. It was hard to hear. They wanted her to be happy, but knew that would take time, they knew personally.

Ace said, "What are you scared of?" kindly. Telling her not to be scared seemed like it could be seen as a belittling thing to do to her. She said she was scared Chisaki would come get her again. She was scared of her nightmares. And scared when she looked at all of the scars she had from him.

Luffy said, "Chisaki is gone. He's ever coming back for you ever again. And you have Aizawa there to protect you right now, right?" Since she was unable to control her dangerous quirk, Aizawa was there for now. Ace and Luffy were immune, but it didn't stop her from going out of control if things took a turn for the worst.

Eri said, "I know… I don't know." They hoped she wasn't feeling embarrassed about it.

Midoriya said, "We all have things we're afraid of. There's nothing wrong with being scared." Uraraka agreed. "Everyone is scared of many things."

She asked if they were scared of things like she was. They listed their fears. None of them were too surprising. Some were failing, being terrible heroes. One of their family members dying. Luffy and Ace were afraid of losing one another the most.

Eri asked when they wouldn't be scared anymore. When she wouldn't be scared anymore. They were honest, and Luffy said that she might be scared for a while. But made sure to tell there was nothing wrong with being afraid. Luffy reminded her of how far she'd come.
"I know it's hard to see things like that now, but one day you'll realize you're stronger than anyone."

There were sniffles on the other side. "Can we ask the nurses a question, Eri?" Luffy asked. She said okay and handed the phone to a nurse nearby. She sounded so sad and lost, but she was safe now. She just needed to learn to control her power.

But where would she go? Surely a nice home? They'd have trouble with someone so traumatized. When would she heal enough to be alright and safe to be myself at all? Probably not for a while but she was on the road to recovery, no matter how long it took to get there. "Hello?"

"Hi, I was wondering if we could come visit her? We won't be harmed by her powers," Luffy asked. He was turned down, saying she needed rest and to recuperate before seeing anything or anybody that reminded her of her recent life. They understood, even if they were disappointed. They wished they could give her a hug, or at least hold her hands and assure her things will be better some day. A promise they knew they could keep for sure.

Aizawa was suddenly on the phone. "Luffy, everyone. There will be no visiting Eri for now. She's emotionally unstable and her power could activate at any time. I'm here to watch that for now," he said in his flat voice. The students all frowned and deflated.

Ace pointed out that he and Luffy would be fine. "And why is that?" They didn't answer, being unable to figure out what to say. "I thought so. Until you're ready to explain how, you can't visit Eri until the professionals say it's all right."

They all sighed but nodded. They were put back on the phone with Eri, but didn't talk long before she had to do some testing and take a bath. They assured her they'd stay in touch and to be strong in the hospital where everyone wants her to get better and be happy.

"Okay," the six year old said quietly.

When they got off of the phone, all of them frowned. "I wish we could see her."

They nodded in agreement with Tsu. Only Ace and Luffy had actually been around her, the others had fought for her sake but had not met her personally. Hopefully they could make her happy some day. Did she know how to smile after the life she'd lived? Did she have a single happy memory? They hoped so. If not, it would be painfully tragic.

There was a knock on the front door of the dorms and All Might walked in, binging a box for Ace. They saw it had a stamp from the hero society. The support hero company that gave out costumes and good quality hero accessories. It was the place that gave everyone at U.A. their costumes.

"This is for young Ace," he said. "I'd like to talk to you in private." The twins nodded, not being separated even by things like this. The box was given to him once they were in private, and he opened it to see the sleeve they'd ordered. It was black and had the Gunhead logo on it. He took off his costume glove and didn't look at the handprint before he slid it on, and it felt thin and light. Like it wasn't even there.

He sighed, liking it a lot. He lit his arm on fire and it stayed perfectly fine. He was happy with this. "I'd like to suggest counseling for young Ace, here," All Might said, getting straight to the point. Both of them grew uncomfortable. "I know you two have always been on your own and taken care of things yourself, but the trauma Ace recently went through would be hard for most people. Especially those as young as you."

Luffy and Ace shared a glance. Luffy gave him an encouraging smile. Ace didn't want to, but he also wanted to be normal for Luffy. So, he agreed to try. All Might smiled and said it was good for him to agree. He said they should speak to the counselor soon. The two got up to follow him out, getting on this quickly and not procrastinating.

When they got to the office, they found it was not a hero, but a licensed therapist. They had their first appointment there. Everyone knew there was no separating them, so they didn't blink an eye when Luffy went in with him. But they made sure to sit in different places.

It was an easy appointment, mostly getting to know one another. Luffy hardly talked, had Ace do all of it with his easy presence there for him. Letting him know he wasn't alone, but also having him speak on his own.

After they were finished, they found Mirio in the hallway, looking sad. "Mirio, are you okay?" Luffy asked in concern. He looked over and immediately smiled, saying he was just fine, and the weather was perfect. Both of them knew something was wrong, and gave him a concerned look that showed they weren't buying his bullshit.

"I wish I could see Eri," he said honestly. "But they said it's too dangerous with her quirk how it is, even if it is under control right now. She must be so lonely. I talked to her over the phone."

The other two could understand. They'd talked to her as well. "Hopefully we can see her soon. And we'll make her smile as best as she can. I think it will be hard, but I want to do that," Luffy said. "She deserves to smile." Mirio smiled softly and agreed. They were the only ones to help her directly, so she only knew them. And they couldn't see her.

"I wish I could be around her like you can. With that ability." The other two nodded, but said it was suspicious to do in front of everyone else. They didn't know how they'd react. "That's true. Nobody would know what it was or where it came from. You might be under a microscope." The twins nodded, saying that was what they most definitely didn't want. "I won't tell anybody. It was what saved us."

He looked at Ace's arm, and asked what was wrong with it. After all, they'd been in their hero outfits when interviewed, since they went straight to questioning instead of the office to get their normal clothes.

The older twin took it off but didn't look at it. "It's some sort of burn after Chisaki tried to blow me up. Don't know when it will go away, but it will always remind me of what I did, accident or not," he explained before hurrying to put it back on. Mirio looked at him sadly and said he was so sorry for him. Ace smiled and waved it off. He said he'd get over it someday, so he didn't need to worry. "I'm going to counseling because of it."

Mirio told them he was offered that as well, but turned it down, thinking he was fine on his own. Ace and Luffy nodded. "We'll all get better, no matter how long it takes. I wonder how long internships will be suspended." Mirio shrugged. It had been a big operation. Lots of injuries, but no casualties.

"I bet Sir is worried about us," Mirio commented. Luffy said he was glad they didn't get in any trouble with anything they'd done on their own. "We had provisional licenses. We were allowed to fight on our own. Even if Aizawa seemed angry with you two. But we saved her and completed the mission, they can't get very mad about it. Have you two been getting any mail?"

"Mail?"

"I've been getting messages from other agencies and pros asking if I wanted to work for them. I've tuned down all of them." Ace and Luffy had gotten no mail. It was strange. Maybe because Ace killed someone. So they said they hadn't gotten any yet. Which was strange. Oh well.

Mirio turned to them and said he was glad he got to work with them. It meant a lot to him to help be the one to save Eri. They grinned at him and said they were glad it was him as well. It was only right for them to be the one to make up for their mistake. They shook their hands. "We'll stay in touch. Will you tell me if you are allowed to see Eri?"

"Absolutely. The same for you," Ace said. Mirio promised. Then they went their separate ways.

-x-

They were practicing their ultimate moves again in the hero training. In the gym they always used. The twins didn't know what to use. Luffy felt he'd learned everything he could at the moment. Ace did as well, not knowing to work on. So, they just started training with their bodies and not their quirks. Well, they were using haki on their legs to throw rubble at one another and break it apart with kicks or punches.

Luffy was better with punches than kicks. It showed, since his kicks were a bit more wobbly. They'd work on tha. Midoriya was working hard on the opposite side of the gym. They were nearest to Mineta, who kept accidentally dropping his balls on them. Ace burnt them if they got too close, which was easy so they didn't get on his case about it. He didn't mean to.

The others were improving while Ace and Luffy felt they were in a rut. Then they saw Midoriya let loose a weak air projectile. Maybe they could try that. "Why don't we try that one out? I'm sure it won't go very well, but we can try," Ace said, pointing to Midoriya's work. Luffy said Ace could try and kick heat air. Then they wouldn't be copying him completely.

"Like when All Might was punching air at us in the exam we took. When we obliterated the training area," Luffy added. Ace nodded and said he'd try. "I'm sure it won't go far, but best to start, right?"

He nodded and took a deep breath, heating his leg before kicking at the rock nearest them. But it didn't go how they expected and a sort of blade of heat came from his leg burning through the base of the rock formation and a piece of the gym wall. Everyone stumbled, and Luffy shouted, "Oh no!" and then everyone was in air boxes to protect them from the crumbling rocks.

The room went silent before Luffy's arms started to shake and he lost control of his boxes, dropping everyone though Cementos had easily stabilized the rocks. Everyone looked at them. Ace bowed and apologized profusely. That he hadn't meant for that to happen.

The handful of teachers behind them watched Ace and Luffy with shocked eyes. The others nodded, saying none of them were hurt, just startled. Luffy's arms were exhausted. Sore and shaking still. He had created solid air away from him and enough to catch each of their fellow students. Using his observation haki to know where everyone was.

"Maybe don't use that attack in doors when other people are here," Midnight said, though she sounded a bit uneasy. Aizawa was there, a break from being with Eri as he told them the horn that her power emanated from had shrunk and was now a small bump. She seemed safe for the moment.

He asked, "Where did you learn that?"

Ace and Luffy said they didn't know. "I've never been able to create air boxes or not in his immediate area." Ace said he'd just never tried it. Luffy said his arms now were exhausted, like he'd been holding something much too heavy that he couldn't carry. Aizawa told them to take a break. Then he asked something strange. "Will you both use your powers? I'd like to see something." They both nodded and Luffy formed a shield and Ace lit his hand on fire. Aizawa clearly used his eraser on them, but it didn't work. Ace's flames didn't go out all the way, they just dimmed extremely. Luffy's shield thinned and thinned until it broke apart.

He released his power and theirs flared back up. He looked concerned and wary. He said to tell no one else about this. The other teachers were surprised as well. Luffy hesitantly asked if they were in trouble. "No, you're not in trouble." They both nodded and went to get a drink of water.

When they got back. Many of the students swarmed them. "I never knew what it was like to stand on something invisible in the air! That was scary!" Kagakure exclaimed. Luffy apologized, saying it must have worried everybody. She then commented on how powerful Ace's kick was. They were both uncomfortable, and saying they hadn't really tried that. Luffy didn't mean to, he just panicked.

"Another show of teamwork!" Ashido cheered. Some of the guys were scowling, and it made Ace and Luffy frown deeply. Ace insisted that they really hadn't meant for that to happen. Sato looked at the unhappy faces.

"Oi! Wouldn't you all want to be congratulated or respected for improving? What's with those faces?!" he demanded, making eye contact with everyone with those expressions. They all seemed surprised before ashamed. Many apologized.

Kaminari said, "I'm sorry, I didn't mean to glare, I just wished I improved as fast as you two and Bakugo. I bet you two got stronger thanks to the work internship." The two nodded, knowing that was probably the reason.

Midnight said, "Stress can increase the pace of improvement. The feeling of fighting for your life can send you shooting forward in terms of improvement. Like when we were attacked by villains and all of your abilities strengthened."

Aizawa reminded them of what Mirio had said. "Experience is power." They all nodded, saying they'd completely forgotten about that. They looked at Kirishima, and saw his ultimate hardened form.

Sero said, "I guess it's not just you two that improvement from that mission." Ace and Luffy were glad that the teachers pointed that out. That it wasn't just them naturally becoming stronger, but that their experiences fueled improvement. The others all said they wanted to do hero work studies as well.

"Yo! Ace, Luffy, come try and punch me as hard as you can!" Kirishima said. "Let's see how hardened I am!" Ace and Luffy did anything to get out of the spotlight and hurried to Kirishima. The stone mountains were back and people were getting back into place. Luffy covered his hand in a very thin layer of hard air so it wouldn't hurt his knuckles, and punched hard. It splintered his hardened body slightly, but did little damage. "Fuck yeah! Ace, you next!"

They weren't using haki as that wasn't fair and wasn't necessary for him since nobody else had it. Ace punched him hard in the gut, but again it did little damage. "Hell yeah! Man, I'm so pumped. Fighting that dude really helped me! He hurt me pretty badly, but I don't think there's anyone that could punch as hard as that guy."

Luffy commented that the first guy who'd come had hit his shield so hard it bruised his forearms pretty badly. "Wow, I thought your shields were invincible." Luffy said that the shield wasn't damaged, just his arms that were touching it. It hadn't moved, but the vibrations had damaged the skin.

"I wish people knew that we weren't invincible. Our powers sometimes hurt us as well." Some of the others heard this, about Luffy's powers hurting him and relaxed. They really were jealous of them sometimes. But that would not stop them from being the best they could be.

Aizawa watched them closely the rest of the period, and they didn't like that. They felt they were under a microscope, like Mirio had said. Only it was from a teacher, nothing else. Nobody else. Hopefully he didn't spread this around. Or they might be screwed. They were lying about the extent of their abilities for their safety. Would they get in trouble for that? They didn't use it to hurt anybody. Surely that would matter most.

After class, Aizawa pulled them to the side. "Ace, Luffy, what were your parents' quirks?"

Ace asked, "What are you asking?" suspiciously. They didn't want to speak of their childhood. He replied that he wanted to know based on how powerful both of them were. They both hardened, Aizawa insinuating their parents were powerful. The opposite. And that was why they threw them away, jealous of their childrens' talents. Threw them onto the street alone to suffer for five long years that would always stay with them.

"Our biological parents had the powers of making every surface they touched sparkle and writing in books without needing a pen. They were weaker than we were at seven," Luffy said in a strained voice which was hiding bitterness. Aizawa looked surprised. He asked where they were. "Don't know, they dumped us when we were seven because we were stronger than they were. It's not like we asked to be this powerful."

Aizawa's eyes widened, seeing a side of them nobody else but Gunhead and Midoriya knew. He looked guilty for once, realizing it was a sore subject that really was none of his business. "I see. I apologize for bringing that up."

They nodded and said they were going to go get lunch now. They walked away holding hands. "It's okay. We'll be fine, Lu," Ace said softly. Luffy nodded, knowing that was true.
