In the end, Nana and Izuku spent as little time as possible downstairs. As soon as dinner was over, Nana immediately dragged her boyfriend back into bed and spent the rest of the night experimenting.

Multiple literal mind-blowing climaxes later, they managed to go to sleep for real.

Nana would have spent the whole next day doing the exact same thing, but unfortunately, she still had to go to school like some sort of child.

Oh well, at least she still got to have fun by beating people up. Speaking of beating people up, Nana's irritation over having other things to do beside her boyfriend vanished when Aizawa told them that they would be doing spars with Class B for hero training.

Izuku winced as Nana internally cheered, "Hell yeah! It's been a while since I got to beat somebody up!"

"You used Kirishima as a baseball bat in training last week," Izuku pointed out, "Doesn't that count?"

"Of course it does! But I still want to do it again!" Nana retorted. Izuku just sighed in response, hoping that nobody would get too badly injured. Nana whistled happily as she went to change, earning confused looks from her classmates.

Class B was never going to know what hit them, were they?

As his students filed into Gym Gamma for the sparring session, Aizawa could only grumble under his breath about stupidly overpowered hero spawn and their stupid, stupid ideas.

Was he going to regret arranging this spar? Probably. After all, the last thing he needed was to give Shimura more people to traumatize.

In the scant few weeks she'd been in his class, Shimura had proven to be just as much of a problem child as her boyfriend (and God, did that make Aizawa wish for death even more than he already did, the realization that Midoriya of all people had seduced All Might's daughter). Aizawa imagined he could feel his hair getting grayer every time Shimura blew up a training ground or dropkicked somebody into next week or came up with another way to torture Bakugo. She was irreverent, sarcastic, mercurial, and way too strong.

Of course, she was also kind, incredibly heroic, and had done more to help Midoriya come out of his shell and given him the confidence he sorely needed than anyone else in the class, but dammit, why did Aizawa have to get all the legacy heroes? Endeavor's emotionally constipated ice sculpture of a son was bad enough, but to have All Might's kid, too? Aizawa was pretty sure that he'd somehow pissed off God (or Nezu, which was really just saying "God" twice,) to get stuck with that hell class.

Aizawa was jolted out of his sleep-deprived grumpiness by the arrival of his fellow teachers for the exercise. Vlad King looked as cocky as ever, while All Might himself wore an expression of mingled eagerness and worry that Aizawa imagined had something to do with the whole "watching your daughter beat people up" part of today's exercise.

"So, Eraserhead," Vlad King began, "I heard you've got yourself a new student! That means our classes finally have equal numbers, right?"

Aizawa couldn't help the groan in his voice as he replied, "Yeah, I do. And it's his fault."

Aizawa jerked a thumb at Yagi, who jumped and looked like he was about to protest, only to stop himself at the last second. Aizawa hoped that that was because he felt guilty for making Aizawa lose even more sleep.

Vlad looked awfully confused, and Aizawa couldn't blame him. The bulky hero asked, "Hang on, what are you talking about?"

Instead of answering, Aizawa just turned and glared at Yagi until he got the hint. Awkwardly, the blonde man cleared his throat and explained, "Ah, Nana-the new student-she's my...daughter. She recently returned to Japan to finish her hero training."

For a long second, Vlad King just stared at the other two teachers; Aizawa could see the gears turning in his head. At last, Class B's homeroom teacher said, "Let me get this straight, All Might. You have a secret daughter?"

"Er, yes?" Yagi replied, looking distinctly uncomfortable.

"As in, you had a child with a woman?" Vlad repeated, still in disbelief.

Yagi's face was bright red now, but he nodded and confirmed, "I did."

At long last, Vlad decided, "Okay then. I didn't expect that, but okay. Tell me, how strong is she?"

Before Yagi could respond, Aizawa turned and slammed his head against the wall behind him, then hissed, "Too fucking strong."

"Really? Well, I'm sure my class will still beat her!" Vlad declared confidently. All he got were pitying looks from the other two teachers.

"Honestly, Vlad, I'll be shocked if she loses," Aizawa told him, "I've been watching her chuck buildings around like toys for two weeks. She beat up Bakugo so badly that she drew a bunch of dicks on his face to gloat."

Vlad couldn't help the chuckle of laughter that escaped his lips at that. When he was done, he snorted, "Damn, All Might, did you raise a rebel or something? I can't believe that the kid of the most goody-two-shoes hero in Japan is a punk!"

Yagi looked distinctly insulted at that. Eventually, he muttered, "Look, you try controlling her."

Well, at least it was good to know that Shimura was the same no matter who she was dealing with. Part of Aizawa, one he would never admit existed, was even looking forward to watching the upcoming spars, mostly so he could watch Vlad's kids react to whatever the fuck Shimura was.

The rest of him was already planning a nice long night with plenty of alcohol to hopefully help him forget about the bullshit he was undoubtedly about to see.

Itsuka Kendo had seen a lot of confusing things in her time at UA. The Frozen Dildo Incident, Setsuna hobbling around the dorms demanding to know who'd stolen her toes, and Monoma getting knocked out and stuffed into a tutu were all pretty high up on the list.

But a new student in Class A, in the middle of the year? That was new.

As Vlad King began to explain the rules of the sparring match-one on one, knockout or ring-out, you fight multiple opponents in a row until you lose and get replaced relay-style-Itsuka felt Reiko lean over to her and whisper, "Who's the new girl?"

Itsuka followed the ghostly girl's outstretched finger to see that there was, in fact, a new student. Above-average height and muscular, with spiky black hair pulled into a ponytail, the girl was standing surprisingly close to the even taller, green-haired boy that Itsuka remembered being called Midoriya. As Itsuka watched, the girl turned and said something to him that made him roll his eyes and pat her affectionately on the head, earning a scandalized look in response. The familiar gesture made Itsuka suspect that there was something going on there, but she wasn't sure what.

Eventually, Itsuka whispered back, "I don't know. She looks kinda strong, though. I'm not sure what her quirk is, but she's buff as hell."

"She's hot," Yui said quietly, her face as stoic and unexpressive as it always was. Itsuka just sighed and decided to ignore the comment; Yui's lack of any sort of filter was bad enough without giving her more ammunition. Instead, she focused back on their teacher just in time to hear him announce the first two combatants, Tsuburaba and that Iida kid.

As the sparring commenced, the two classes mixed, with members talking to friends or bantering as they watched the surprisingly close matches. Itsuka took the opportunity to sidle up to Yaoyorozu. The taller girl greeted her warmly, but with a twinkle in her eye that suggested she knew exactly why Itsuka had come over.

"So, I noticed you guys have a new student in your class," Itsuka observed in as close to a neutral tone as she could manage.

"I assume you mean Shimura?" Yaoyorozu replied just as Iida sent Tsuburaba flying out of the ring with a crash, the boy's air constructs dissipating quickly.

Itsuka nodded as she asked, "Yeah, what's up with her? I thought UA didn't accept transfers."

"She's a...special case," Yaoyorozu responded evasively, "she definitely surprised us, though."

"What kind of special case?" Itsuka prompted, perhaps a bit too eagerly. Judging by the amused look Yaoyorozu gave her, she'd recognized her information gathering for what it was, too.

"The kind that I'm looking forward to watching fight against you guys," Yaoyorozu told her.

Sighing, Itsuka tried a different approach. She asked, "What, is she super strong or something like that?"

"Something like that," Yaoyorozu agreed with a smile.

"Come on, she can't be that strong if she only joined halfway through the year," Itsuka scoffed dismissively. The conversation paused for a second as Kaminari was suddenly sent flying by Yui turning a pebble into a boulder under his feet.

The twinkle in the black-haired girl's eye only got stronger as she retorted, "I mean, she kind of wiped the floor with Bakugo, so I'd say she's pretty strong."

Itsuka couldn't help the way her eyes widened and her jaw dropped. Numbly, she repeated, "Wait, she beat Bakugo? As in, angry, explodey, "I'm-gonna-kill-you" Bakugo?"

"The very same," Yaoyorozu confirmed with a grin.

"How?" Itsuka demanded, her eyes locked on where Shimura was talking to that brown-haired girl-Uraraka, that was her name-both of them laughing and joking while the ring was coated with a sudden layer of frost thanks to Todoroki wiping Monoma off the map.

"You'll see," Yaoyorozu said mysteriously, "oh, you'll see."

Itsuka couldn't help the ominous shiver that ran down her spine as she wondered what the fuck this Shimura was about to do.

Knowing Class A, it was probably something big, stupid, and insanely unfair.

Nana watched the series of fights with growing boredom. What, she liked fighting people, not watching other people fight! Nana just wanted to punch something and scare these people who had never seen her before, was that too much to ask?

As fun as watching Kirishima and this Tetsutetsu guy beat on each other was, it had been going on for like fifteen minutes now!

"Nana, why are you so violent in hero training?" Izuku asked lightheartedly as they watched.

Just as lightly, Nana retorted in her head, "What? Fighting is fun!"

Izuku just sighed, "That's not an answer, Nana."

"Well, too bad," Nana teased, "You'll just have to live in ignorance."

The back-and-forth was interrupted as Uraraka turned to Nana and asked, "Hey, what do you think Class B is going to do when they have to fight you?"

"Ooh! I bet they're gonna be pissed!" Mina chimed in, making Nana laugh.

"Now, let's be reasonable here, guys," Nana said, "I'm just going to aim for making them scream in terror. Does that sound good?"

Uraraka laughed, "It sure does, Shimura!"

"Guys, please stop encouraging her," Izuku begged.

Grinning, Nana told him, "Izuku, I'm afraid you're outvoted here."

Uraraka and Ashido nodded in agreement. Then, at last, Kirishima and Tetsutetsu struck one last blow and finally collapsed, toppling over like damaged buildings. The match was declared a draw, and then Vlad King called out, "Itsuka Kendo and Nana Shimura!"

Nana turned back to Izuku. Sweetly, she asked, "Do I get a kiss for good luck?"

"Please, you don't need luck," Izuku snorted, making Nana's heart flutter at the admiration in his voice.

"Okay, but I expect a kiss as my reward for winning," Nana informed her boyfriend.

Izuku nodded and agreed, "Deal."

With that, Nana turned and marched into the ring, eyeing her opponent, a lean, athletic girl with orange hair.

Just before the match began, the girl said, "I don't think I've met you before."

Grinning as she raised her fists, Nana replied, "I don't think you have."

"Well, my name's Kendo," the girl announced, "and I'm not gonna let you win without a fight."

Nana couldn't help the way her grin turned sharp and savage; her heart sped up and the world around her slowed down, just like it always did when the adrenaline started rushing through her veins.

"That's exactly what I was hoping you'd say," she drawled, and then the fight was on.

In the end, things went about as Nana expected.

Kendo charged, her fist swinging towards Nana's midsection as it exploded outwards, becoming massive and powerful. Normally, Nana would have just floated over it and then landed on her attacker as they looked around wildly for where she'd gone, but now she was trying to keep some tricks up her sleeve. Even if she won this fight, she'd have more afterwards, so she figured it would be smart to keep some of her capabilities in reserve.

Luckily, Nana had more than enough power to fight head-on, too.

Nana called up One For All, and the familiar glow surrounded her limbs as she met Kendo's blow with her own. Nana saw the other girl's eyes go wide as her attack was negated. For a split second, the rushing wind around them put Nana and her opponent into a struggle to hold their ground, a struggle that Kendo eventually lost as Nana poured more and more strength into her punch. Kendo staggered backwards, losing her footing as her defenses were overwhelmed by Nana's strength, and then Nana started her own attack, leaping forwards to slam a powered-up fist right into Kendo's gut. Kendo went flying backwards, slamming into the crowd; a tightly-woven net of vines from the weird praying girl Nana had seen earlier caught her before she could fly any further. A quick call from the teachers declared Nana the winner by ring-out.

Nana stood confidently in the center of the ring, hands on her hips. She could hear disbelieving whispers among Class B, who had just seen their class president taken out almost instantly.

As Kendo staggered to her feet, gasping for breath, Nana called out, "Sorry, but it isn't the size that matters, but how you use it!"

Nana imagined she could hear Izuku's groan from behind her, and it only made her grin wider. Class B was looking at her as though they weren't sure they had heard her right, Kendo among them.

The orange-haired girl asked, "I'm sorry, did you just say what I think you said?"

"Yep," Nana confirmed. Kendo just stared at her a while longer, before Nana's next opponent was announced.

A minute later, Nana was facing a guy who literally looked like he was made of swords.

"So, your name's Kamakiri, eh? You look badass as fuck," Nana told him.

Kamakiri didn't even reply, only letting out a hiss as he charged, meter-long blades springing into existence on his forearms. He brought them down in an x-shape as he reached her, a move that might have cut Nana in two.

Had she not been floating over Kamakiri's head, of course.

Nana heard a gasp from Class B as Kamakiri whirled in search of her. Someone yelled, "Hey, what the fuck?"

Nana just laughed and aimed a punch right at Kamakiri's head from above. Before it connected, though, the insectlike boy raised an arm above his head, and Nana hissed in suppressed pain as one of the smaller blades on his arm cut up her knuckles.

Rubbing her hand a few times, Nana quipped, "Not the talkative type, huh? Well, that's fine."

Once again, though, Kamakiri didn't respond. Instead, he leaped straight up, far faster than Nana expected. She yelped as one of his blades swung towards her head, and she didn't quite manage to dodge fast enough; as Nana ducked, she felt her hair twang and snap, and a sizable chunk of it fell away.

Oh well, it wasn't like she didn't need a haircut anyway. Desperately searching for a way to get this fucker out of the sky, Nana grabbed Kamakiri by the arm, biting back a hiss as another blade scraped her hand, and threw him down with as much strength as she could muster. Backed by One For All, Kamakiri made a sizable crater in the concrete floor of the arena, but he still managed to stagger to his feet.

As Nana floated in the air, feeling her hair stick out in spikes and swirls that came to her collar instead of her back like it used to, she called out, "Hey, man, I like this new look! Thanks for the trim!"

Then, without hesitating, Nana dropped out of the sky feet-first, her body humming with the power of One For All. Kamakiri looked up just in time to get two boots to the face. He and Nana disappeared into a cloud of debris.

When the smoke cleared, Kamakiri was unconscious on the ground, and Nana was wiping off her bleeding knuckles, her newly-freed hair reminding her of the style she'd worn when she was in UA the first time around. She asked Izuku, "Hey babe, how do I look?"

On the other end, Izuku gasped, "Holy shit, Nana, you look great."

It was at that moment that Nana decided to keep her hair this short, wild style. If Izuku liked it, that was good enough for her.

Nana realized that the rest of Class B was also staring at her, and she said, "Come on, guys! Please tell me that that's not the strongest guy in your class! I'm getting bored!"

As they carried Kamakiri out of the ring, Nana again reached out to Izuku to say, "I'm coming for that kiss, Izuku. One more win, and then that's all of Class B down."

"Nana, I would kiss you anyway, you know that," Izuku reminded her.

"I do," Nana replied cheekily as she maintained her savage, bloody grin, "It's just more fun to take that kiss."

When Nana's last opponent stepped into the ring, she almost laughed.

This skinny purple-haired kid looked as exhausted as Eraserhead! What was he supposed to do to her?

This guy barely looked threatening in the slightest; of course, that probably meant he was just hiding it. Nobody got into the hero course without being worthy of at least a little respect.

As the countdown started, Nana felt Izuku's voice ring in her head, telling her, "Nana, you have to be careful, that's Shinsou! His quirk is-"

"I don't want to hear it," Nana interrupted, wrinkling her brow as she focused on her opponent.

"Huh? Why not?" Izuku asked, radiating worry.

"Because," Nana replied, "I want to fight this fair and square. If his quirk relies on surprise, well, I'll just have to give him the best shot he can before I win."

She heard Izuku sigh in her head, but he did as she asked. Nana loved it when Izuku did the smart thing and let her kick somebody's ass.

Nana realized that Shinsou was still staring at her, an unreadable look in his eyes.

"That's an awfully strong quirk you have there," he drawled, "it must be nice to have that kind of power at your fingertips."

"Someone sounds envious," Nana observed, dropping into a fighting stance right as the bell sounded to start the match.

"And what if I am?" Shinsou asked.

Nana wasn't sure why Shinsou didn't attack, but hey, she wasn't going to turn down the opportunity to punt somebody into next week. As she charged, she retorted, "Well, then I say have a nice trip-"

There was a flash, and Nana couldn't move. It felt like her body wasn't obeying anymore, and when a grinning Shinsou told her, "Go walk out of bounds," her feet began to follow the command.

Inside her head, Nana was yelling, "Oh, COME ON! What the hell is THIS? I am not going to lose to this STUPID SHIT!"

But no matter what she tried, she couldn't break free. Nana felt like a void had settled over her mind, and it was just like the one she'd been reborn from, endless and formless, a place where she couldn't move or think or breathe.

Suddenly, her mind was alive with color and lights and sounds and images she'd never seen before; they felt almost like memories, but they couldn't be, she'd never seen any of the people that flashed by her mind's eye in half a second before!
Then, there were the voices; they echoed in her mind, unfamiliar yet ingrained somewhere deep inside her, echoing and changing like nothing she'd ever heard before.

"What the hell is going on?"

"I thought we were past this, dammit!"

"Now is not the time."

Then, as the chorus of voices faded, the image of a face appeared, one Nana didn't recognize; it was thin and sallow, sickly and corpse-like, with dry, cracked lips, but the eyes were alive. They shone with an inner light that took Nana's breath away, pooling with sorrow deeper and more agonizing than anything she had ever imagined, blazing with hope as strong as her own. The rest of the figure's body was swallowed by shadows, but Nana's gaze was trained on that heartbreaking face.

All of it happened so fast, like a fragment of a fraction of a heartbeat, but it felt like an eternity as Nana stared into that face

"Who are you?" she asked.

The gray-haired face didn't answer, didn't even seem to hear her. In a voice that didn't come from its lips, it said, "I'm sorry."

And then it was gone, replaced by another voice, one that lifted Nana's heart and filled her soul.

"Nana? NANA!"

There was a rush and the feeling of a million volts of electricity flowing over Nana's skin, and then an explosion of wind and force that she recognized as One For All itself. Nana gasped, and she was free.

In her mind, she asked weakly, "What the hell was that?"

"Nana! You're okay!" Izuku replied, overjoyed, "I'm sorry for interfering, but I thought that Shinsou's quirk might be able to brainwash both of us at once, so I nudged you to break you free!"

Literally none of that made sense to Nana, but she knew what she needed to; Shinsou could control people with his mind, and somehow, she'd broken free of it.

Speaking of Shinsou, he was yelling, "How the hell? Not AGAIN!"

Normally, Nana would have made another quip, but honestly, she was just ready to end this fight now. That was enough brainwashing shenanigans for today, thank you very much.

So Nana staggered to her feet, realizing that she was literal inches from the edge of the ring, and summoned the power of One For All to surround her like a warm, familiar cloak.

Then, Nana used her own quirk, and shoulder-charged Shinsou at top speed, flying right into him like a human bullet.

Shinsou was cut off in the middle of his confused rant, and sent flying out of the ring. Once again, vines caught him, but even as Nana, and Class A, were declared the winners, Nana was already rushing towards Izuku to claim her prize.

Nana pulled Izuku tight, ignoring his blush, and hungrily claimed his lips for a passionate kiss.

Somewhere behind them, Class B was watching in unimaginable levels of confusion, but Nana and Izuku's classmates just watched with amusement and indulgence, used to the couple by this point.

When the kiss ended, Nana barely managed to sit through the class wrap-up until she finally got a chance to pull Izuku over to where Toshi was waiting, looking just a little conflicted for some reason.

Grabbing both of them, Nana murmured, "Guys? We need to talk."

"About what?" Izuku and Toshi asked in unison, perplexed looks on their faces.

Nana swallowed hard, remembering the storm of images and voices that had raced through her empty mind.

"About what just happened," Nana replied, "because One For All just did something weird again."
