After her talk with Izuku, Katsumi expected to go home. She waved him off and got her phone out to message her dad that she was ready to leave, all the excitement of the day had worn her out. All she wanted to do was lay on her bed and sleep.

At that point, Katsumi just didn't have it in her to argue, so when he replied that he was in fact not going to be taking her home quite yet as he had paperwork to do she just gritted her teeth and went to go wait for him.

The teacher's office was on a different floor from her classroom, and she had a little difficulty finding it with her father's shoddy directions. She ended up stopping an upperclassman to get some directions, a smiley girl with long periwinkle hair.

"The teacher's office?" the girl leaned towards her, her eyes wide, gleaming with curiosity. "Why are you heading there? You're not in trouble, are you?"

"Nejire…" a gloomy voice came from the girl. It was a tall dark-haired boy, glancing at Katsumi nervously. She hadn't even realised they were walking together.

"No I'm not in trouble-" she laughed as convincingly as she could. "I gotta wait for my Dad."

"Dad?" The girl leaned closer to her. "Does your dad work here? Is he one of the teachers? How cool! Which one is it-"

"It's down the hall to the left," the boy mumbled, interrupting what would have been a never-ending stream of questions.

Katsumi smiled as wide as she could in her current irritated state, "Thank you!"

"Oh Katsumi, I'll only be a couple of minutes or so-"

"Sure." Katsumi slid into a chair at the edge of the room, pulling out her AirPods case. She popped one into her ear- she had lost the other one a while back in an alleyway and still hadn't gotten around to replacing it. How annoying, she thought. If it had happened before her birthday, she could have asked for a new set of headphones. Then again, she was glad it didn't. That was the last good day she'd had before her little 'definitely not huge problem' arose.

"Don't make a habit of this, Yagi." Katsumi's attention snapped to the familiar, deep voice of her homeroom teacher, Aizawa-sensei. But he wasn't talking to her; his sharp gaze was fixed on her father, god she really didn't like the way the Japanese used last names. "She shouldn't be in here."

"Oh, loosen up, Aizawa!" A tall woman with jagged purple hair leaned back from her desk, grinning at the scowling man. "I'd love a chat with little All Might Junior over here."

"Get on with your work, Kayama," Aizawa grumbled, shaking his head. She laughed, giving Katsumi a little wave as she sat back at her desk.

Katsumi smiled at the woman, though her gaze drifted back to her homeroom teacher. She hadn't really noticed him earlier that morning, too distracted with being late. But now, with a better look, she took in his dishevelled appearance: the way his long dark hair framed his face, the perpetually annoyed set of his brows, the sharpness of his jawline, and the hint of stubble he hadn't bothered to shave off. In a strange way… maybe, no- yes- was he? …Yes, she decided yes as he reached over his desk to grab a folder with his rough, strong hands.

She felt her lips curl up as she realised her homeroom teacher, the man she would have to spend the next few years staring at every morning, was super hot.

"Katsumi, what's wrong?"

"Huh?" Katsumi jolted, snapping out of her thoughts. Her father was looking at her with a puzzled expression. She could feel the eyes of the other teachers on her, though Aizawa did not look up, entirely uninterested.

"You were giggling," her father said, one eyebrow raised.

"Oh!" Katsumi's cheeks burned. She hadn't even noticed. "Yeah, sorry. It was, um... my podcast." She laughed awkwardly as she pointed to her single AirPod.

"Try to keep it down," Aizawa said curtly before her dad could reply, not even glancing up.

"Yes, sir!" Katsumi squeaked, her face flaming even hotter. His eyes flicked up for a second, raising an eyebrow in mild curiosity, and she quickly ducked her head back to her phone.

With the same thud of a dead body being dropped into a ditch, Katsumi collapsed onto the sofa, a long drawn-out growl coming from her throat. She heard the cling of the car keys being placed into a bowl as her dad shut the front door.

"Was today really that bad?" Katsumi could feel the weight of his body sink to the end of the couch as he sat down.

"Yeah!" Her top half snapped around to look up at him, "Because of you." She glared at her father. "Not only did you make me late but 'cause you wouldn't stop that stupid match Izuku ended up being knocked out!"

Toshinori went to respond, only for Katsumi to jump up onto her knees, hugging a pillow tightly.

"Worse of all," she whined, shoving a bright red face into the pillow, "now the entire class thinks I like Izuku-"

He blinked, pressing his lips together tightly. Feeling a laugh tickle the back of his throat he coughed, "Really?"

"Yeah," Katsumi moaned childishly as she rocked back and forth, "cause of the way I was acting while he was fighting and then stupid 'Kacchan' said we were dating and they all just ran with it!"

He managed to catch the laugh that threatened to escape as he watched his daughter flail around. "Well, are you dating?"

She stopped, instantly lifting her head up, mouth gaping open. "No!"

"Okay…" he scratched the back of his long skinny neck as he took in her cherry-red cheeks, "Do you like him?"

Katsumi's eye twitched, "No. I do not."

Toshinori shrugged, allowing a little chuckle to escape his lips. "Then don't worry about it."

"Ugh!" Katsumi threw herself back, bouncing against the cushion. "And I won't forget how you snubbed me from MVP!" She sprung back up onto her knees, hitting him with the pillow. "Admit it I deserved that!"

"Well- yes-" he started.

"Ah-ha!" Grinning, she laid back down, stretching her arms back.

"But I couldn't give it to you!" Toshinori argued. "Not right after your classmates found out about you being my daughter," he palmed his temples, "That would just look rigged."

"Mmmm sure." She hummed.

Neither of them said anything for a moment. Katsumi stared up at the wooden ceiling as her father's mind ticked.

"What did Midoriya say to young Bakugou?"

"Oh," Katsumi sat up onto her elbows to look at her father, "basically, Izuku told him he wasn't tricking him about being quirkless 'cause he borrowed his power from someone else."

"What? Why-" Toshinori groaned, rubbing his brow. "I suppose it is fine seeing as he doesn't believe it… Why on earth would he-" He sighed, already knowing the answer. "They have history don't they?"

"Yup." Katsumi hummed, crossing her legs. "Izuku started talking about making the quirk his own and stuff so he could beat him." She looked into her father's sunken eyes, "Thats why you let the match go on isn't it?"

"Yeah," He nodded, glad she understood. "I wanted to give Midoriya an opportunity."

"...I guess."

She could accept that, after all, that's what Izuku wanted or whatever. But next time she just wanted to be there with him, to be able to fight beside him and protect him.

He would be in danger very soon, she had managed to avoid putting that inevitable target on his back herself, but when certain people discovered just what quirk he had flowing through his veins? Her chest felt like it was collapsing in on itself, pressure building up inside her, blocking her airways and making it hard to breathe. In and out Katsumi.

He had no idea how much danger receiving All Might's power would put him in. All Might was neglecting to prepare him for what One for All came with. That pissed her off.

Maybe that was unfair though. Her father probably didn't even know.

'A villain who hated your daddy injured him a long time ago so now he has two forms. But you don't have to worry about that Sumi, he's not here anymore, he won't hurt me or you.'

She still didn't know if he had told her that because he believed it or just to ease her worries. But if he did know, then he was the most incompetent and neglectful father and mentor to ever live.

"Dad?" She sat up properly. No way, he had to just not know. She had to confirm it though.

"How does a quirk like One for All happen anyways?" Was that a good place to start?

His brow scrunched for a moment, the question was a bit random. "Stockpiling power over generations-"

"Yes but-" she interrupted, a little frustration slipping through, "how did that start?"

"Well," he scratched his head, "There was one person who had a quirk ability to pass on quirks and they passed it on to another."

"But how would they even know they could do that?" She had no clue how she should bring it up.

Her dad just shrugged. Screw it.

"It would be bad if a strong villain found out about it," Katsumi turned, injecting her voice with as much casualness as she could, "All Might's power is transferable? Anyone with half a lick of ambition would want that for themselves."

It's not like that topic hadn't come up before in their conversations, but she just needed to get the conversation there.

Her dad paused before he looked at her very seriously. "You don't have to worry about that, I still have plenty of strength in me. There was one man who was a big trouble but-"

"Who?" Katsumi interrupted quickly. There it was.

Her dad leaned over, resting his elbows on his thighs, "You know my stomach injury?"

"The reason you look like that most of the time?" She laughed, pointing at his skinny arms.

"Yes- Damn," he looked at her, face painted surprised, "that felt mean."

Katsumi's eyes promptly widened as she realised her impolitness. Isn't that exactly what she got annoyed with Izuku for? "I didn't mean it like-"

"Haha," her dad grinned, "I know. Yes, that injury, well it came from a mighty foe, a man who for generations tried to steal One for All, many of my predecessors fell to him, but I avenged them." His words were spoken with a lightness as if he was simply breezing over it. A light touch on a deep and vast subject. It was enough for Katsumi though. Besides she wouldn't want to push it further, he was obviously trying to avoid talking about it too much. She understood not wanting to talk about dark things better left in the past. Well, she had to confirm it a little more.

Katsumi smiled, going along with his lighthearted tone, "Did you get him arrested or..?"

"I believe he is dead."

"Oh, are you sure?"

Toshinori looked at her, "Don't worry, he's gone."

So he did think he was dead. That was clear now. There was no reason to lie about it anymore, she wasn't a little girl anymore.

The little relief she felt quickly dispersed as her mind continued to spin. How crazy it was that she had been so worried about a comment about her clothes and that Izuku had another female friend earlier. She had bigger problems than that petty shit.

Katsumi nodded, feeling slightly sick. She shoved the feeling to the room in the back of her mind and shut the door tight.

She could fix it herself.

Ding

"That Midoriya?" Toshinori asked.

Katsumi took out her phone, the picture she had taken on her birthday of her dad and Izuku peeping through the clear bits of her phone case.

1 new message from 'unknown number': Hello, it's Yaoyorozu

"Oh! Yaoyorozu!" A smile jumped onto Katsumi's face.

"Ah, that's the black-haired girl, right?" Toshinori leaned over to peek at her phone, "You were paired with her during the battle training?"

"Yeah we had lunch together- she's cool, and our quirks work similarly as well."

"From what I remember she's the top recommended student." Her dad remarked, a smile on his face. What a good student for Katsumi to make friends with.

"Good influence then." Katsumi chuckled, almost as if she had read his mind. She got up off the sofa, "Imma get changed outta this uniform now."

"Um before you do-" Her dad sat up, "How's Midoriya? I know you were talking after school but you weren't together during the lesson. I would have thought you'd have been hanging out with him-"

"Oh uh, well he made some other friends and I didn't want to stop him from getting closer to them y'know?" Looking away she chuckled, "Plus I wanted to make some new ones so…"

"You can befriend his friends too, you know?"

"Good point!" Katsumi grinned, scratching the back of her head as she backed away. "Well, call me down for dinner!" She waved cheerfully as she walked to the stairs.

"Hey! This isn't a restaurant! You need to help!" Her dad called after her.

"Gimme a break!"

Tuesday 2nd April 20XX

Heyyy! Glad you remembered

Katsumi added unknown number to contact 'Yaoyorozu'

17:11 Yaoyorozu

Katsumi, seeing as you are allowing me to call you by your first name I think it would be rude of me not to do the same.

Please call me Momo.

17:12 Katsumi

Aww okay Momo

Katsumi has changed 'Yaoyorozu' to 'Momo '

um, im almost a bit nervous to even ask but people don't actually believe what Bakugou said right?

17:14 Momo

Because of your reaction.

17:15 Katsumi

ughhhhhhhhhhhhhhhhh

okay whatever

just to be clear

17:19 Momo

Of course Katsumi.

17:20 Katsumi

You're welcome to borrow any whenever you want.

17:21 Katsumi

awh thanks

dont forget what i said about me helping u with combat

17:21 Momo

I must admit you're abilities are impressive.

By the time they actually finished chatting and she shut off her phone to stare at the ceiling, she was grinning ear-to-ear. When she had met Yaoyo- Momo at the entrance exam she hadn't thought much of her. Now she had a feeling they were going to be good friends. When she had complimented Katsumi, telling her she should have gotten MVP she had felt a little annoyed at the pity, but also… seen. For some reason her specifically validating her like that was really comforting. Perhaps it was because a girl so clever and properly recognised her physical abilities as a positive thing? It was just such an encouraging feeling.

She groaned, all those warm feelings washing away. It was properly not a good idea to get too attached right away, they were training to become heroes, and if something happened to them, Katsumi couldn't afford to let it affect her.

"No," Katsumi took a sharp breath in. Nothing was going to happen to her, or any of her classmates in fact. The teachers would protect them, her father would protect them and she would make sure that soon there would be no threat anymore. Not like they even knew there was one yet.

For her second day at school, she did not ask her dad to take her, she wasn't about to risk another lateness. She had a feeling her teacher would not be so forgiving about a second lateness so early in the year and she didn't want to inconvenience her homeroom teacher… Though if she was late it would mean he would have to scold her- that wouldn't be the worst thing in the world.

No, she was not about to be late. As it was obvious she couldn't rely on her dad to wake her up she set an extremely loud alarm on her phone and put it on the other side of her room, right next to her giant Mirko poster. The idea was for her to have to get up to turn it off, and it worked. For how badly her luck had been recently, waking up well-rested and on time was a win she was more than happy to take. She had taken a pill the night before to sleep so she had slept through the night well too. It was a necessity now as she could probably guess there would be more physical training on the horizon.

Once she had finished putting on her uniform, she left her room to get some breakfast, closing the door behind her.

Since she wasn't in a rush, she was able to put on the uniform the way she wanted. She still refused to tuck the shirt in, her top button undone, and her tie loose. She added safety shorts under her skirt and a pair of creme leg warmers over her white trainers and shoved her blazer in her bag. With her usual mix of bracelets, a couple of silver necklaces under her shirt and her UA uniform (Katsumi style) was fully realised.

It was her last safe day. As she slabbed on a thick layer of chocolate spread over her toast she decided she should make sure to enjoy the day. No getting annoyed at little things.

The train was packed that morning. Katsumi had never really taken the train that much and she was completely unprepared for the morning rush. She was glad to escape the uncomfortable crowd and get into the street as she made her way to the school.

Outside was fresh, spring still not completely warming up the air just yet. Debating on whether or not to put her blazer on she walked along the pavement. She was almost at the school now, there was no point.

To her disappointment, she hadn't actually escaped being squished between the bodies of strangers just yet as when she reached the school gate she was met with a strange sight. It was just as crowded as the train- with news reporters.

She groaned as she surveyed the area, did she really have to go through that? They seemed to be harassing the students, shoving microphones and cameras in their faces as they asked them questions. Was this normal? UA was a pretty famous school but this seemed a little excessive, was there no villain attacks to report on?

Something felt off, other than the crowd that was. The hairs on the back of her neck stood up and she slowly turned around. Her eyes surveyed the trees behind her for a moment. Her brow furrowed, was someone there?

Whatever. It didn't matter. The door was shut. She was going to have a good day.

"Excuse me!" Katsumi shouted over the chattering of the crowd as she pushed through the reporters. They absentmindedly made a slight effort to shuffle out of the way.

"Miss!" A female reporter in a blue suit turned to her, holding out the microphone. "Are you aware All Might is teaching at this school?"

"Oh," Katsumi deadpanned. "That's why y'all are here."

"So you know? Have you been taught by him? What is it like?"

"Oh piss off." Katsumi rolled her eyes hard as she moved her out of the way. "You'll make me late."
