Katsuki made a move to scoop Kana up and make a quick escape before things could escalate further into chaos, choosing to ignore that she called him Deku instead of papa in favor of making a run for it – He could deal with that later. Katsuki was still confused as fuck, but there could be a multitude of reasons why she did what she did and quite frankly he was relieved. Maybe he had some luck on his side. He only made it two steps towards the two when he saw it, the raw, unfiltered expression shown on her face plain as day and he just froze. Despite how much his brain was screaming at him to get out of there, he couldn't find it in himself to move.

"You're back!" Kana cried, throwing herself into Deku's arms and hugging the confused boy much like the way she always hugged Katsuki. Her body was trembling like a leaf, her emerald eyes were swimming in tears and her voice was breaking, "I missed you so much!" she sobbed into his shoulder, tears and snot running down her face despite how much she was sniffling. Deku didn't even seem to mind the mess she was wiping all over him, instead he just scooped her up and rubbed her back gently. "I - I'm here now?" He said hesitantly, his face twisted softly in concern. His undivided attention was solely on her as he attempted to calm her down, and Katsuki wondered how he was so calm when a little girl he had never seen before in his life clung to him as if her life depended on it and said she missed him. Fucking saints.

"D-daddy said you w-won't remember me because I'm from th-the future." she blubbered, "But, I-I want you to remember me! Everyone keeps saying 'Who's she?' 'Who's that?' and I don't like it!" Katsuki frowned, that was news to him. She was always smiling when she was introducing herself , so how was he supposed to know she didn't like it when people she already knew asked who she was. He could understand it, he wouldn't like it either. But why hadn't she told him? He would've listened despite common belief. He wasn't heartless. He felt extremely guilty for not noticing before, but it wasn't as if he was just going to magically know how to parent a child because he had one come from the future.

Before Deku had a chance to respond, Kana continued. "I know you don't know me yet," she sniffled, calming down a little, "I'm Kana Bakugou," she whispered. "I'm your-" she cut herself off as she eyed his hero costume and the crowd of his classmates that were watching the scene like a real bunch of extras. Did they really have nothing better to do?

Katsuki narrowed his eyes, she had been about to say she was his daughter, he knew because that was the exact same thing she had said to him. What had stopped her? Yeah, he was so fucking glad she didn't but he was still curious as to why. Deku looked confused about what she had been about to say also, he could tell by the look on his face, but he didn't get the chance to ask.

"Holy shit!" Someone behind Deku yelled, he already knew who it was without looking. Another self-proclaimed member of the 'Bakusquad', Sero. The raven haired boy gaped at Katsuki with wide eyes. Well, even if he didn't like the attention, he was glad for the distraction. Tape face looked back at Ashido, Kirishima and Kaminari for confirmation and the three idiots just nodded enthusiastically, too enthusiastically if you asked Katsuki. What the hell were they so fucking excited about? Was it that surprising he had a kid in the future? He knew he wasn't good with them and he certainly never thought about having one before, but no seventeen year old teenagers who were training to become a hero thought about having kids. He wasn't the only one.

"I know, right! And get this - Bakubabe is so protective over her!" Raccoon Eyes smiled and she looked like a proud mom watching her kid interact with their own child for the first time. Okay, was that what this was about? Seriously? Tch, they thought he wouldn't be protective of his kid? Well, maybe he didn't know he was being protective of her, but wasn't that a fucking given? Take care of your fucking children or don't have them at all.

"Yeah, I thought he was going to kill Mi-"

"Shut up!" He snapped, he didn't want to hear about that again. "And you two!" Katsuki rounded on Kirishima and Kaminari who had just been about to talk and pointed an accusing finger at them, "Don't think I fucking forgot about the stupid shit you two just pulled. If Deku hadn't caught her, what the fuck do you think would have happened?" The two idiots bowed their heads in shame, neither one answering, not that he was asking for a legit response. They were fucking heroes in training and they almost dropped a small child after running around blindly. She could've gotten seriously hurt for fucks sake.

"See!" Mina squealed, jumping up and down like she had just won the lottery. "Look how protective Daddy Katsuki is!"

"Don't fucking call me that, Raccoon Eyes!" He growled, okay that was way more embarrassing than he would've thought it would be. He never wanted to hear them call him that ever again. It was like they purposely found things to say and do just to piss him off. Didn't they have any other hobbies? Like picking on Shitty Hair's shitty shoes? Those crocs were seriously fashion suicide, yet the redhead loved them. "Okay Daddy Bakugou!" She said smiling, he cringed.

Sero threw an arm over her neck and pulled her close, the two began whispering animatedly. Sero's eyes jumped from Katsuki to Deku to Kana and his face lit up in a shit-eating grin. He could tell what they were whispering about without having to hear any of it. It was how Deku was her papa and how he didn't even know because Katsuki wouldn't tell him.

Katsuki glared at them "Go do something else with your life and leave me the fuck alone." he snapped and turned back to Deku, surprised to see the nerd was already looking at him. He raised an eyebrow.

"A daughter, huh, Kacchan?" He asked, his emerald green eyes shining the same way they always did when he was excited, but there was something different about it, he couldn't put his finger on it. It was just a little off.

Katsuki whipped his head away, he could feel the heat rise in his cheeks. Why did he have to look at him like that? He was going to give himself away with how he was acting. Katsuki fucking Bakugou doesn't get embarrassed. Except he just did, and it was because the stupid nerd just looked at him and said 'daughter' and 'Kacchan' in the same sentence. How pathetic? Seriously.

A fit of laughter bubbled up from Izuku's mouth and Katsuki had to pretend it wasn't the sweetest sound he had ever heard because he was supposed to be mad goddamn it. Mad that the stupid nerd had embarrassed him and had the nerve to laugh at him. What the hell was that about? He had no idea what he just did warranted laughter. It wasn't funny.

"Who the fuck do you think you're laughing at, Deku?" Katsuki growled, stomping up to said boy. The heat in his cheeks was getting deeper, but maybe he could pass it off as anger. Right? That would totally work.

Deku tried and failed to keep a straight face as he said, "No one, Kacchan."

"Daddy's embarrassed!" Kana said, giggling while she covered her mouth with one hand and pointed at him with the other.

"I'm not fucking embarrassed about shit!" Katsuki growled, glaring at Deku. Of course, he couldn't actually pass it off as anger. Kana gave him a curious look and Katsuki realized he never told her that they weren't together and gauging from her reaction to seeing Deku it wasn't going to sit well with her. How the hell would he even bring that subject up with her? She was a kid, she wasn't going to understand. He wasn't even so sure she would like him anymore if he told her what he did to not deserve to be with Deku, and that really fucking hurt. But he welcomed the pain, it wasn't anything compared to what he did to Deku.

"Of course, not." Deku chirped before looking at Kana and shaking his head as if to say he didn't actually believe him. Kana giggled and copied Deku. Katsuki felt a familiar warm feeling in his chest at the sight, but he squashed the feeling down immediately. This wasn't something he was allowed to have. His younger self made sure of that, and he didn't have anyone to blame but himself. Katsuki glared at nothing in particular and crossed his arms.

"Awe, Kacchan. Don't pout." Deku said, not even trying to conceal the amusement in his voice.

"I'm not fucking pouting!" What the hell? He- he was not pouting.

"I'm sorry, don't be grumpy." Now he was calling him grumpy? Maybe it was true, but the nerd was definitely trying to get on his nerves.

"No you fucking aren't."

"Okay, maybe I'm not that sorry." Deku relented.

"Tch." He wasn't actually angry at Deku, not that the other boy knew that, and he definitely wasn't going to tell him the real reason why.

"Pa-Deku?" Kana said suddenly.

Deku blinked like he was processing something and looked at Kana, "What is it?"

"I'm all yucky, now." she said, gesturing to her face. Her nose was red and her eyes were puffy, it was kind of disgusting in an... endearing kind of way?

"I'm sure Kacchan would have no problem cleaning you up," He said with a grin, "I actually should go change, too." Deku started to pass Kana to Katsuki but her eyes went wide with panic and she clutched onto Deku harder, "Wait! No, don't go! I don't want you to go!" she buried her head in the crook of his neck and refused to let go. Deku gave him a questioning look. "Daddy, please! I don't want him to go!" she pleaded.

Katsuki stiffened when Kana refused to let go of Deku and eyed the others, hating the questioning looks they were giving him. "It's okay, Kacchan. I can take her with me - I mean if it's okay with you. Oh! But I guess that's kind of weird? You're her dad after all. I don't know why she wants me to stay, uh, maybe we could go together? We don't have to! It was just a suggestion because she looked really sad and I don't want her to cry because of me-"

Katsuki slapped a hand over his mouth and rolled his eyes, "Stop fucking muttering, I'll get a cloth. Just stay in the common room." he said. Who knew what she would end up calling him once they were in private, and he assumed Deku wouldn't try to go change unless Kana let him go without crying. Maybe he could keep that information on the low-down until they could sent her back to her own timeline.

"Oh, okay, Kacchan."

Kana looked at him and Katsuki immediately knew what she was going to say, "I'll be back in fucking two minutes." he said, before she had a chance to open her mouth.

"But-"

"Do you trust me?" he asked, looking into her big green eyes.

Kana looked at him but nodded.

"Then just wait here with Deku. I'll be right back."

Kana nodded again, and Katsuki walked away.

If Katsuki learned one thing from Kana's out burst when Deku tried to leave, it was that something must have happened to said boy before she came back from the future. If he remembered right, she had said something earlier about him disappearing from the flower shop she was in. At first he shrugged it off because she was the one that went back in time and it must have only looked like he disappeared, but it had to have been more complicated than that. If he was understanding correctly, the three of them were together before Deku 'disappeared' and she was sent back in time. So it made sense she was clinging to him more than Katsuki, although he did notice she would glance his way often, as if she was checking to see if he was still there. As if he was going to leave, he couldn't just get up and walk out without bringing Kana. Especially since she wouldn't go anywhere without Deku, and his secret was more safe out in the open ironic as it was.

He noticed not long after Deku first showed up, that she would try to call him papa only to cut herself off when she looked at his hero costume and his other classmates. So as long as Deku didn't change out of it or go anywhere with her in private, he assumed it was safe to say she wasn't going to call him papa, therefore crisis averted. But then that left him with only one option; stay in the common room and pray to any fucking god that would listen that she would let Deku leave so he could take her back to his room and away from his loud and obnoxious classmates.

The sky outside was already darkening, turning soft shades of orange and pink as the sun set, bathing him in warmth. Katsuki allowed himself to slump in his seat and relax, for the first time not in any immediate danger of exposure. Deku seemed to be focused on Kana like everyone else, but every now and again he would glance at Katsuki with a look he couldn't quite decipher, and before he even had a chance to try, Deku would look away. He knew that Deku had questions, like why Katsuki's daughter was clinging to him so much, but he didn't ask, which was super fucking surprising. Normally he couldn't stop talking, especially when he saw some interesting quirk, or quirk side effect. Kana kind of fell into that category, coming from the future and all.

"We need to get you some proper clothes!" Deku said, tickling Kana, "Let's go ask Yaoyorozu, look there she is!" Kana looked up as said girl walked in, smiling as soon as she saw her. "Auntie Momo!"

"Hi, Kana."

Katsuki had been watching Deku and Kana play in the common room from his spot by the window. He couldn't help but notice how much more calm she was around him and Deku compared to Kirishima and Kaminari, like she was matching her energy with whoever she was with, as if she was in complete sync with them. It was intriguing to say the least. How a kid as small as her was more in tune with people than many of the adults he knew.

Deku helped Kana change under a blanket that Yaoyorozu held over their heads. The raven haired teen was giggling, but when she met Katsuki's eye, she smiled knowingly and Katsuki froze. She seemed to sense his panic from across the room because she held a finger up to her lips in a 'shh' motion and smiled again. God fucking damnit, how the hell did she figure it out? It can't be that fucking obvious.

"Daddy! Daddy, look!" Kana ran up to him, smiling as she spun around and showed him her new clothes. She had on green flowery overalls and a purple long sleeve shirt, brown boots and her hair was up in a ponytail. She looked pretty fucking cute.

"Looks good, brat." he said. Kana beamed at him and turned around, but turned back just as quickly with a look of confusion.

"You still don't look happy, daddy." she said, crawling onto the couch beside him and sitting down. "I thought seeing papa would make you happy," she whispered loud enough for only Katsuki to hear, "but you look more sad, daddy."

Katsuki blinked. He wasn't expecting her to notice that. Fuck, he didn't even notice it himself. He didn't feel sad, maybe a little bitter, but that was normal. Maybe that was why Deku kept giving him those looks.

"Papa doesn't know who I am, I should be sad, not you." she said, Katsuki snorted. That was probably true. Maybe this was a good time to ask her about that, "Yeah? and why haven't you told him?"

"'Cause I'm not allowed to," she huffed, she looked sad, but wasn't on the verge of crying... yet.

"Who told you you're not allowed to?" He didn't remember saying anything like that. Maybe someone from the future?

"Papa did. Big papa I mean. He said never call him papa while he has his hero costume on 'cause s'not safe."

So he was right. She did have a reason that had to do with his outfit, but she still called him 'Daddy' in front of Best Jeanist and Aizawa-sensei. "Oh, yeah? Why did you call me daddy when I had my costume on then?"

She paused before cringing, "I forgot."

"You forgot?" he repeated bluntly.

Kana nodded her head and looked down. "I'm sorry." She murmured.

"Tch, it's fine here, but you should be more careful. Deku probably had a good reason for a rule like that." Kana nodded her head. Well, she was way more intelligent than he thought she was, even if he already thought she was smart. Maybe she would understand what he told her about him and Deku.

"Daddy?" she asked,

"Hmm?"

"I want to go home, I miss my papa and daddy. I love little you and little papa, but s'not the same." She said quietly, twiddling her thumbs. He could've guessed that already. It was completely understandable, he wouldn't want to be stuck with a whole bunch of people that he knew that didn't know him either. Aizawa-sensei was probably working on finding a way to send her back at this very moment. Or at least find out if she would just go back after a certain time limit. He knew some quirks worked that way, not all of them, but some.

"You remember that man that was going to take care of you before?"

"You mean Shouta?" she asked,

"You knew him?" he said incredulously, staring down at her.

"Of course!" she chirped.

"Then why the hell were you crying?"

"I wanted to stay with you and papa." she said matter of factly.

Katsuki sighed, it didn't really matter anymore. "Anyway, he's going to find a way to send you home. He and All Might are trying to find a solution."

"Really? I can go home soon?" she asked, jumping up onto her feet excitedly, her eyes shinning while she smiled that brighter-then-the-sun smile.

"I would fucking guess," he snorted, his lips quirking up in the smallest of smiles.

Kana surged forward and hugged him, leaving a small kiss on his cheek before she jumped off the couch. "I wanna go see papa now," she said.

"Wait a minute," he said suddenly, sitting up a little straighter. He didn't really want to ask her to do it, but it was probably better that way.

"Yes, daddy?" She asked curiously.

"Could you do something for me?"

"Anything, daddy!"

"Could you, uh, keep calling him Deku, even if he changes?"

Kana scrunched up her face in confusion, "Then papa won't know who I am,"

"I know..."

"O-okay, daddy... I'll do it for you, but why?" Kana looked up at him with sad eyes, but even he could see she wasn't going to leave it alone until she was satisfied with the answer.

"Uh, we - we're not together... yet." He'll leave out the part where he's like completely sure she's not even from the same universe, because that was a whole other can of worms.

"You're not? But don't you love papa?"

"I, uh, I do..." he mumbled, his cheeks reddening. That was his first time admitting it out loud. That shit's fucking hard. How the hell did people just openly say embarrassing shit like that? Even to someone as unbiased as a small child? It was like ripping out your own beating heart and giving it to someone else who could do just about anything with it.

"Then why?"

"It's complicated," it wasn't that simple. If everything was as simple as an innocent child saw it, the world probably wouldn't need heroes to begin with. But things are never that easy. Katsuki had a front row seat to that bullshit.

"But you love papa, right? What's comp'icating 'bout that?"

Katsuki frowned, "I did some messed up shit, you wouldn't understand."

"So say sorry," she said, her brows furrowed like she was trying to understand.

"It's not that fucking simple."

"Papa says it is. He said 'say sorry and mean it, then go from there'. No one is perfect, daddy." she said softly, sounding way older than a four year old should.

Katsuki didn't reply right away, maybe that kind of logic was true, it just didn't seem right for him to get a happy ending like that after everything he did. Kana continued, "Do you think little papa doesn't love you? He does! He said he loved you since you were little like me!"

Katsuki narrowed his eyes, "He said that?"

"Yup!"

"Are you actually only fucking four?" He asked seriously.

"Yes! But, I turn five soon!"

Katsuki nodded, "Huh," then said, "Why don't you go play with Deku, now? He won't stop looking at me with those goddamn puppy dog eyes."

Kana looked up to see Deku shifting in his seat and glancing at them every so often like he wanted to join them, but didn't want to intrude. "Okay, daddy!" she got off the couch and ran over to Deku who smiled happily as she jumped onto his lap.

Todoroki walked in and blinked when he noticed Kana, staring at her with a blank face. Katsuki wrinkled his nose, yay more fucking people.

"Uncle Sho!" Kana beamed, "Hi, uncle Sho," she said as he sat down on the sofa across from her. "I'm Kana. I'm from the future! Katsuki is my daddy."

Icyhot blinked again and nodded, "Is he now?" he said with the smallest of smirks. He didn't seem surprised in the least. Katsuki could see the recognition pass in his heterochromic eyes. Damn bastard was an idiot when it came to the real world - well, not as much now as when he was a first year - but, for some odd reason he could pick up similarities between people or certain traits and fucking guess their relationship. What a fucking weirdo. He was a weirdo because Katsuki refused to believe he was just observant.

"Yup!" she said, bouncing on Deku's lap who smiled a little nervously. "Uncle Sho?"

"Yeah?"

"Could you use your fire?" Kana asked, he could feel her excitement from across the room. Why she was excited about his fire, he didn't know.

"My fire?" Todoroki asked in surprised.

"Yeah!"

Icyhot flipped his palm up and let a flame dance across his hand. Kana crawled towards it, but when she reached out, the flame went out.

"Be careful."

"It's okay, uncle Sho, heat doesn't hurt me 'cause of my quirk!"

Katsuki blinked. He had completely forgot she was old enough to develop a quirk and if he was being honest, he was really interested in what kind of quirk she had. If it came from Deku's side of the family, or his. Maybe a combination of both?

"Watch!" Kana threw her hands in the air, as if she was throwing confetti and when she closed her hands, little sparks went off in the air above her head. "And I can do this! Fire, Uncle Sho." she demanded sweetly.

Icyhot lit another flame in his hand and Kana reached out and grabbed it. Literally grabbed it, from his palm, letting it move in her hand and then the flame was floating above her hand. "See! Deku look!" She turned and Deku watched in fascination.

"Deku?" Icyhot repeated in confusion, raising an eyebrow and looking at Katsuki. The ash-blonde boy just glared at him as if to say shut up. Of fucking course he knew. At least he was smart enough to not comment on it.

"That's amazing! It could almost be mistaken for Pyrokinesis, but you can also control explosions from a distance. Do you also sweat nitroglycerin like Kacchan?" Katsuki could practically hear the gears shifting in Deku's head. The nerd was probably going to write that down in one of his notebooks. It was pretty cool. He could remember Inko had a telekinesis quirk. Controlling her explosions as well as fire from a distance, huh. So a combination of both.

"Uhuh!" she grinned and turned, "Did you see me, daddy?"

"I saw." He said while grinning, "Impressive." Of course a daughter of his would have a crazy impressive quirk. The only thing he would be worried about is her ending up like him, but he guessed there was no way that was happening since she was Deku's kid, too. She was too sweet for that.

Kana beamed and blew out the flame, but her smile promptly dropped when Uraraka and Kirishima made an appearance.

"Hi, Kana! I'm Och-"

"I know who you are, Auntie Ochako," Kana huffed, "You don't know me... Hi, uncle Eiji!" she said, not even looking at Uraraka.

"Hey, little missy!"

"Hah, get rekt Round Face." Katsuki said from across the room with a smirk. Guess Kana didn't like her.

"Hey! Kacchan, that isn't nice." Deku scolded.

"Yeah, Bakugou." Kirishima echoed, as he picked Kana up, placing her on his lap when he sat down. Uraraka sat beside him.

"Tch, I'm not fuckin' nice, Deku."

"You are, sometimes, when you think theres no one is watching." Deku murmured, Katsuki's smirk dropped and he stared at him for a moment, there was a tightness in his chest, but it wasn't uncomfortable... more pleasant. He blinked when green eyes met his and he looked away quickly. Instead he looked at Kana who was pushing Round Face over to sit between the two with a frown on her face. Kirishima looked at her curiously but didn't comment. He narrowed his eyes as he tried to decipher the look Kana was making, it was familiar... Crimson eyes went wide as he realized. It was... possessive. That's fucking rich. Kana has a crush on fucking Kirishima. Katsuki nearly burst out laughing, she didn't not like Uraraka, she saw her as a threat.

Maybe she was more like him than he initially realized.

"Papa wants to change, but he won't say so." Kana said approaching Katsuki a few minutes after Round Face and Shitty Hair left. God that had been a real riot watching Kana do everything she could to deflect Kirishima's attention away from Uraraka and the idiot hadn't even realized what was happening.

Katsuki stood up suddenly, "Let's go, if he says you can go with him. I'm going to my room." Maybe this would be a good time to sort out his mind in the peace of his bedroom. It had been a really long fucking day and he needed alone time to process it all. Kana wasn't bad to be around, he actually enjoyed it, but she was also the reason for his conflicting thoughts. And now that he didn't have to worry about her calling him papa, he didn't mind letting her stay with him.

"Okay!"

Katsuki walked over to the green haired boy and nodded for him to come, Deku beamed and followed.

"What's up, Kacchan?"

"Daddy wants to go to his room, but I wanna stay with Deku!" Kana supplied, Katsuki could tell she was still wary of leaving the green haired boy even though she knew he wasn't her papa yet. He wasn't the one she was actually worried for, but loved him all the same.

"Do you mind?"

"I don't mind at all, but it's getting late, Kacchan. Is it okay if she stays with me?"

Katsuki nodded, "I trust you," he said nonchalantly. He could physically feel the happiness radiating off of Deku as he said those words, but his got that look again that he always got when Katsuki said something more genuine like that. "What's with that look? Are you really that surprised?"

"What? No! No, I know you trust me, but that's the first time you've ever told me, is all. It makes me happy to hear it..."

"Tch, whatever, nerd." Katsuki said, ignoring how warm he felt just knowing how happy Deku was from a single sentence.

They stepped onto the elevator and Kana grabbed both of their hands. In that moment, it almost felt possible. To be happy with Deku.

The elevator doors open and the two stepped off, leaving him alone. And the feeling was gone. "Bye, daddy!" Kana chirped.

"Bring her to my room when you wanna go to sleep or whatever. The doors open."

"Sure, see you later, Kacchan. I'll bring her back before bed." Izuku said, smiling sincerely. He couldn't help but notice that weird look in his eyes was gone. He looked really happy for some reason. It was scary in a way he couldn't describe and Katsuki couldn't help but feel like he was saying goodbye, which was really fucking ridiculous because he was literally going two floors up.

Katsuki nodded as the doors closed, "Later, 'Zuku." he said softly just before the doors shut. He swore he saw Izuku's smile soften, but somehow looked even happier.

When Katsuki got to his room, he quickly changed into sweats and a tank top before collapsing into his bed. He felt as emotionally exhausted as he did when he blamed himself for All Might's downfall, but it was okay. He finally found the resolve he needed. He didn't just not deserve Izuku, Izuku deserved someone better than him. Someone who could make him smile like that all the time, not someone who had actively tried to take it away. And that was okay. His eyes stung a little, but Katsuki shut them and sighed.

He didn't know how long he laid there, but it felt like only a moment before his door burst open, slamming violently into the wall. Green lightning entered his room and Deku was standing next to his bed with Kana in his arms before Katsuki had the chance to sit up,"What the-" His green eyes were wide with panic and he looked scared. Katsuki immediately knew something wasn't right.

"Something's wrong! She- she's disappearing, Kacchan! And I don't think it's because she's going back!"
