Comments of the day!

To emiya-excalibur. Yes. YEET Endeavor to the sun. Go ahead and give Kazumi all the hugs you want. The Midoriyas are possibly the most pure family in MHA, anyway!

Axlexington: Thank you for the fish. I will feed them to my cat. And then put the leftovers in the fridge also to feed to my cat.

And finally, to The Keeper of Worlds. I will absolutely make Kazumi troll her brother when it comes to Ochaco. It's going to be subtle until certain events happen that kind of… strengthen the idea in her mind. Then it's turned up to eleven.

On with today's story!

Izuku let out a sigh as he and Kazumi approached UA High.

"You nervous?" she asked him.

"A little. How about you?"

"Well, I don't know what the practical has in store, but I'm sure you'll do better than me on the written portion. You've always been smarter."

"But I was helping you study, so you might do better than you think."

She shrugged, then a voice caught them both off-guard.

"Get out of my way before I set you both on fire." Bakugo pushed past them and she glared at his back.

"Hard to set water on fire!" she yelled.

"SCREW YOU, WATER WITCH!"

Listening to his sister and Bakugo bicker was oddly comforting and familiar territory. Kazumi kept walking as Bakugo turned around to talk smack to her.

I'm going to do it. I'm going to be a hero!

He tripped over his own feet.

Or I'll just die.

He was stopped just before he hit the ground and found himself floating in midair.

"Are you okay?" asked a very feminine voice. He looked to see a pretty girl with pink cheeks and brown hair. Internally, he freaked out as he was set upright. "I stopped you with my Quirk. Sorry for not asking, but I figured you wouldn't mind me helping you."

"Uh…" Izuku stammered like an idiot as his sister came back.

"Jeez, this is all so nerve-wracking, huh?" the girl laughed.

"Yeah, it is!" Kazumi agreed.

"See you two inside!" The girl walked off and Kazumi looked at Izuku.

"You okay, buddy?"

"I talked to a girl!" he squeaked. Kazumi rolled her eyes.

"You didn't actually talk, dummy. You stammered. C'mon, we're gonna be late."

Inside the auditorium, Present Mic explained how the practical worked. Izuku and Kazumi had been assigned to the same battle site, oddly enough, while Bakugo was on a completely different site from the two of them. Then, they found out about the three types of enemies plus the fourth one.

"A zero-pointer… that seems odd," Kazumi whispered to her brother.

"I know… but you'll have no problem with any of the others, I bet. Me, I don't know what I'm going to do."

"Sounds like a final boss to me."

"Would the two of you kindly stop chattering?" asked a boy a few rows up, glaring at the Midoriya siblings. "It is quite distracting."

"S-sorry!" Izuku mumbled.

With that, they changed into their gym clothes and headed out to the battle center. Kazumi viewed the gate. She wouldn't admit it to Izuku or anybody else, but the gate was intimidating to her. It reminded her of being a child on the streets, going from house to house to find food. Closed doors, no opportunities… She then glanced at her brother, who was shaking with fear.

"Izuku, you're gonna do fine," she assured him, putting her hands on his shoulders.

"You should be focused on the test ahead," stated the boy who'd snapped at them for talking earlier. "Not on your friends."

Whispers broke out about Izuku being so nervous, everyone writing him off as done for already. Kazumi let out a growl. She hated it when people called her brother weak because he didn't have a Quirk. She'd thought UA would be different, but here were the other applicants proving her wrong.

But when it was time to go in and kick ass, she ran in without a second thought.

For eight minutes, she ran around like a madwoman, slicing into robots with her water or smashing them into buildings with huge jets of it. One almost stepped on her, but she turned into a puddle and evaded, much to everyone who saw's shock and awe.

Then the zero-pointer arrived on the scene.

Her eyes widened. There was no time to think. She turned and ran, then heard a sound not unlike a jet taking off. She whirled around to see…

Izuku?!

Her brother was rushing towards the robot in midair and reeling his arm back… taking it out in one punch. She stared in shock, then noticed the girl who'd saved him earlier freeing herself from under some rubble. Right where the robot had been about to step.

She was reminded of when Izuku had saved her when they were little.

Oh my God. He… he has a Quirk!

Her eyes teared up. Yep, she was a Midoriya—overdone tears and all.

I'm so proud of you—wait, are your legs broken!? You moron!

He was plummeting to the ground, his legs and right arm broken. She knew exactly what was going through his mind and she couldn't do anything to stop his fall. But luckily, gravity girl had her beat as she slapped Izuku across the face, making him float just inches from the ground before she released him. Then promptly threw up.

"Izuku!" gasped Kazumi, running to her brother's side.

No. Shit, I'm a bad sister, no no no no!

"Gotta… get one point…" he whimpered.

"You can't get any. You're down three limbs."

"And time's up!"

Izuku looked ready to sob as Kazumi put her hand on where the bruising was the worst, willing it to cool down. She was grateful that he'd figured out that aspect of her power. The cooling down part, at least. Heating up was still spur-of-the-moment anger, but being able to make cold water was useful for soothing injuries. Still, her brother passed out from the shock and pain.

"Is… is he alive?" the gravity girl asked.

"He's alive. He's an idiot, but he's alive." She sighed. "I had no idea he could do that…"

"None of us did."

"No, I mean…"

Kazumi was cut off by Recovery Girl arriving on the scene. The Youthful Heroine healed Izuku without much effort and looked at the girl made of water.

"Mind taking him to the written exam, missy?"

"Not at all." Kazumi slung Izuku's arm over her shoulder and smiled. "Thanks for healing this idiot."

"Oh, it's my job to heal idiots. Good luck with yours."

Kazumi smiled and headed off.

"I failed."

"You don't know that—"

"I failed the entrance exam! I barely passed the written portion and on the practical I got a big fat zero! Tell me that's not failing!"

Kazumi cringed.

It had been a week since they'd taken the UA exams and Izuku had been like that since they got home. She hadn't even been willing to tell Inko what she got on the practical out of solidarity for her brother.

"Focus on what's important—you have a Quirk! How did that happen?"

"Oh, um…"

"Could I tell my sister about One For All?"

"Your sister?"

"Yeah. She's my closest friend and I trust her more than anybody else."

"Not yet. You'll need to get used to your power first. Once you have control over it, you can tell her."

"I guess I'm just a late bloomer."

"I knew the toe-joint thing was bullshit!" She looked excited. "You were so upset when we were kids, but I knew you could do it!"

"I didn't even make it into UA!"

"Again, you don't know that!"

Izuku sighed.

"I'm going to my room."

He flopped onto his bed and stared up at the ceiling.

When he and Kazumi had hit their third year of elementary school, the family had moved to a slightly bigger apartment in their building—one with three bedrooms instead of two. The reasoning behind the move was simply because Izuku and Kazumi were getting older and each of them needed their own space. And more privacy. It hadn't been easy to get used to having his own room at first, but he learned to deal with it. Even though Kazumi still suffered nightmares he doubted she'd ever really outgrow, she learned how to deal with them quietly and not wake up the whole household when she had them. Plus they'd become much less frequent.

"IZUKU! KAZUMI!"

Both teens rushed out of their rooms to see their mother holding two envelopes as she looked panicked.

"They're here! Your test results!" she gasped, holding out the envelopes. Each of her kids took theirs into their respective room.

And that was when Izuku had one of the biggest shocks of his life.

He'd made it into UA.

As for Kazumi, well, the fact that she'd also made it in wasn't much of a surprise. After all, she had more skill with her Quirk and had gotten actual combat points on the exam alongside twenty-five rescue points for trying to administer first-aid to Izuku. Not to mention her brother had helped her study for the written portion. They were also going to be in the same class—Class 1-A. Both of them were ecstatic.

The Midoriyas were going to UA.

The physical tests that Aizawa put them through put Kazumi at the fourth spot for their class and Izuku at the twentieth. Miraculously Aizawa decided not to send him home and instead, they went back inside to commence with the rest of the school day. After school, the Midoriya siblings were walking home together like they always had.

"Wait!" called a voice. It was the boy with the glasses who had admired Izuku's tenacity.

"Hi," Kazumi greeted him.

"I apologize for snapping at you both during the entrance exams. I was very nervous and your talking wasn't helping."

"It's fine," Izuku laughed. "Besides, we really shouldn't have been talking."

"Are you three walking to the station?" asked a fourth voice. It was the gravity girl who'd had the infinite score on the softball throw.

"Yeah," Kazumi replied. "You wanna walk with us?"

"Sure. Oh!" She clapped her hands. "I'm Ochaco Uraraka. And you're Tenya Iida, Deku Midoriya, and…?"

"Kazumi. Kazumi Midoriya."

"A-and my name's Izuku Midoriya! The o-only person who calls me Deku is Kacchan, and that's to make fun of me."

"That's not very sportsmanlike," Iida mused.

"I think that it would make a great hero name! Plus, it's pretty cute, don't you think?"

"Deku it is, then!"

"You're hopeless," Kazumi sighed.

"Wait, you said your last name's Midoriya… and his last name is Midoriya… are you two related?"

"We're brother and sister. But we're not related by blood, which is why we don't look anything alike or have similar Quirks."

"Oh, phew. I thought you guys were gonna be like secretly married or something."

"Ew, no."

"I'm pretty sure you'd prefer to marry Kacchan," teased Izuku.

"Okay, that's even more 'ew, no'."

"So, um, Kazumi—can I call you Kazumi?" Ochaco asked.

"Only if you let me call you Ochaco."

"Deal."

"Anyway, I saw that your Quirk is water-related."

"Actually…" Kazumi turned her hand to water. "My entire body is the result of my Quirk. I'm made of water and I have hydrokinesis. I can also thermoregulate the temperature of the water I use to a certain degree, no pun intended."

"That pun was totally intended," Izuku snickered.

"Yeah, it was. But, um… that's about it. Other than turning myself into a puddle, there's not much else I can do."

"That's still amazing!" Iida insisted. "If your body is made entirely of water, then you don't have to worry much about physical attacks!"

"I do, actually. My body being made of water has nothing to do with it."

"I'd still like to see more of it in action if you don't mind."

"Maybe during hero training. I heard All-Might's one of our teachers!"

"Oh, that's right! This is gonna be great!" cheered Ochaco.

"You fucking moron."

Izuku bit his lip as he heard his sister's voice.

"You broke your damn arm. Again. And you almost got yourself killed blocking Kacchan's attack. It was bad enough that you passed out."

He looked over to see Kazumi sitting in a chair by his infirmary bed. Her ice-blue eyes were narrowed and her hair was steaming slightly at the ends. That was how he knew she wasn't as pissed as he thought.

"Yeah. Sorry, Kazumi."

"Moron. 'Sorry' doesn't fix your arm."

"It's like I said—I need to get control over my Quirk and this will stop."

"Izuku. You lied to me, didn't you? About how you got your Quirk."

"I…"

"It's fine. I understand why you won't tell me." The steam on her hair stopped as she sighed.

"It's not because I don't trust you!"

"I know that. You're not the type to hide things from people you trust without reason. Obviously, somebody asked you to keep quiet. So… I'm not going to pressure you to tell me yet. But if you keep getting hurt, I will be pressing the issue and you're gonna crack like a tennis ball under a hydraulic press." She smiled. "You and Ochaco won, by the way. Congrats."

"How did you do?"

"I was up against Ashido and Aoyama. Yaoyorozu and I won without a problem."

"That's good."

"Recovery Girl says you're clear to leave, by the way."

"Good."

Izuku got out of bed and followed his sister back to the classroom once he was ready. As soon as he did, he was accosted by his classmates who were impressed with what he'd done in the exercise. Then both he and Kazumi found out Bakugo had left. Izuku ran out to catch him while Kazumi went with him to ensure things didn't go south. She knew how sore a loser Bakugo could be.

"Kacchan, you can't just give up!" yelled Izuku.

"You hid your Quirk all that time…" Bakugo said in a low voice, slowly turning around. "And you let me think you were weak. You let your sister fight your battles for you. How stupid are you?"

"I wasn't hiding anything. The truth is… somebody gave me this Quirk." Kazumi's eyes widened. "My body can't handle the power right now. But I'm going to learn. I'm going to control it. I won't be able to become the hero I want to be until I learn how to use this borrowed power."

"Don't give me that crap! 'Borrowed power'—how stupid do you think I am?! Who the hell would do that?!"

Before Izuku could answer, All-Might came seemingly out of nowhere. He began to give a speech about pride and potential that Kazumi swore had to have come from a movie or something. Maybe a movie about superheroes?

"It doesn't matter. Deku isn't my rival, anyway. Right, Water Witch?"

"Damn straight."

"Well, then! The three of you should strive to better yourselves! Now, go home and get some rest—we have a big day tomorrow!"

"Yes, sir!" Kazumi nodded and saluted All-Might as the hero left and Bakugo did, too.

"Better ourselves…" murmured Izuku. Kazumi thought of how her brother used his newfound Quirk and then put two-and-two together.

"Wait. Izuku… did… did you get your Quirk from—"

"Shh! Not so loud!" He put his left index finger to his lips. "We'll talk at home."

And they did. Izuku explained how All-Might was injured and searching for a successor and how the Number One Hero had chosen him for the position. He told his sister about the ten months of intensive training and cleaning up the beach and even about the hair. When he was done, Kazumi was quiet. Then she looked at him with tears in her eyes.

"It's like I told you in middle school—you had everything you needed to be a hero except that one genetic detail. And now, thanks to All-Might, you have that detail you were missing."

"He asked me to keep it a secret, but you figured it out so quickly… I wasn't going to tell you until I figured out how to control it without breaking my arms."

"I'm glad you told me. Now I can really be in your corner. You're going to be the next Number One, just like you dreamed about when we were kids. Just… be careful, all right? I don't wanna lose my brother."

"I will. Thank you, Kazumi." He held out his arms (the cast had been removed before he left school) and smiled sheepishly. "Awkward sibling hug?"

"Awkward sibling hug."

They hugged each other for a moment, then as they patted each other on the back…

"Pat, pat," they said in unison.

With Kazumi in on the secret of One For All, I had somebody at school other than All-Might who could help me figure out how to control the power. And like All-Might said, I had to help her strive to do better. Even when it was down to helping her figure out how to control the temperature of the water she used. But I didn't realize just how helpful her water abilities would turn out to be when we faced real villains for the first time. And that came sooner than either of us thought.

So that wraps up chapter 3. I'm moving pretty fast, but I think you guys are liking this so far. I'm getting a lot of reviews and it's making me happy, which makes me write faster and write more for all of you. Every chapter of this story seems to be longer than the last.

Next time, we'll hit the USJ incident and start up the Sports Festival.

So long and thanks for all the fish!
