She's the Man

Author's Note: The gender swapping is gonna get a little confusing with a lot of He/She, his/her, him/her mix ups where Izumi is concerned so I apologize in advance.

Also For those following the other Midori Arc, no worries this will not in anyway shape or form keep me from updating the other fics. Can't say the same about the Kingdom Hearts fics because once I fixed one problem, two more popped up so I'm a bit frustrated at this point. Anyway, ENJOY!

Chapter 4: First Day

Izumi could already tell the first day of school was going to be difficult. From the moment her and Izuku moved into the on campus dorms, nerves and tension were on an all time high. They had an entire floor to themselves, but she didn't expect that to last. Sooner or later this place would be crawling with students, and the game of mistaken identity would begin.

To keep up appearances, Izuku got his haircut the same as Izumi, a change he had to get used to. On top of that the two had to figure out together what his costume would look like, and what features to add. The end product wasn't particularly her style, but she wouldn't be wearing it for very long. She had plans for her own costume, one that would show the differences between them when the time came.

"What the hell did I get myself into?" She muttered under her breath and adjusted the school uniform. Izuku locked himself up in his room with the homework packets All Might had shoved at him, leaving her to her own designs. The fact he was content staying in his room for hours at a time just showed another angle to how her and her brother differed. They may look alike, but people were bound to realize the differences once Izuku started school as himself. "I better avoid social interaction for the time being."

Particularly, she added silently with a grim face, if Bakugo was around. She'd riled up during the exam and felt comfortable doing so because she hadn't expected to see much of him afterward. Now that they were going to the same school the two of them were bound to run into each other, and that didn't bode well for herself, or Izuku. If she said or did the wrong thing, Bakugo would most certainly notice.

"Maybe I'll get lucky and he's not in my class." She mumbled and pulled back the door to Class 1A.

"Don't put your foot on the desk!"

"AH!?"

Immediately her hopes were crushed when Bakugo's loud obnoxious voice mixed with the authoritative one of Tenya Iida. Didn't that just figure? Her two least favorite people were in her class, and Bakugo just happened to be seated directly next to hers. Great, she closed the door behind her quietly, just great.

"Just what high school did you graduate from you side character?" Bakugo laughed.

"I attended Somei Private Academy, my name is Tenya Iida." Iida adjusted his glasses and frowned in disapproval of Bakugo's behavior.

"A private school, so you're some kind of elite? Looks like I'll have fun crushing you!" Bakugo grinned at him making Iida shudder back.

"Crushing? Should an aspiring hero really be saying those words?"

"Tch…" Bakugo turned up his nose, then glanced over at the door where Izumi stood, hands in pockets her eyes narrowed on the two of them. Instantly his grin spread and his eyes went deadly. "Well well well, if it isn't Mr. Top Score… guess your sister wasn't talking out of her ass after all."

"Hello, Kacchan." Izumi muttered as she walked past a stunned Iida to set her bag down on her desk. The books hit the floor when Bakugo kicked the desk against the wall and Izumi's temple throbbed with annoyance. Don't provoke him, don't aggravate him.

"You know I went looking for you after the exam, and you just up and disappeared. I figured you'd bombed so bad you didn't want to show your sorry face." He laughed and stood up so they were toe to toe. He bent his head down trying to get her to look at him. "Imagine my surprise when I found out you not only beat me, but also got top marks. You really are a fucking nerd, Deku."

Seriously? Izumi's teeth clenched. What the hell was so attractive about this? Her brother was a goddamn idiot.

"Be pissed all you want, but I gave you fair warning at the exam not to mess with me." She turned her eyes on him finally, fight and aggravation lighting in them. "So back off."

"Don't mess with you? How about you not mess with me? You've been holding back… but don't think that just because you scored the highest in the exam means you're better than me. I'll fucking kill you."

"You're right," she crossed her arms. "You could easily beat me… if you'd stop being a dick,"

"Say what!?" Bakugo growled but iida moved between them.

"Now, now, no more arguing. We're all classmates." He moved Izumi over a step so he was between her and Bakugo, then bowed his head. "I owe you an apology, my name is Tenya-"

"I know, I heard your introduction earlier." She heard the snap in her own voice, and knew Izuku wouldn't sound anything like that. She sighed heavily, and glanced around the classroom. All eyes were on them. So much for avoiding social interaction. She offered a strained smile. "I'm Izuku Midoriya, it's nice to meet you."

"Midoriya-kun, you were inspiring during the practical exam. You figured out how the test would be scored and I had to admit but you're-"

"I didn't and I'm not," Izumi correctly quickly and felt annoyance and irritation bubbling. She tried desperately to hold onto the reigns of her temper but her mouth wouldn't stop moving. "People were getting hurt, and all anyone was doing was running away. That isn't what a hero should do when others are in danger."

"Ah! Curly head!" Ochaco broke the tense moment when she walked into the classroom. She jogged in to join the conversation, "I knew you'd get in, that punch of yours was amazing!"

The girl was like a breath of fresh air. Izumi smiled, unable to help it.

"Thanks… and thanks again for the save." She glanced at Bakugo who was staring intensely with a firm glare. Frustrated Izumi pointed at Ochaco, surprising her. "It's because of her that i scored higher than both of you. The two of you out performed me when it came to intense combat power, and strategy, but when I saw her get hurt I didn't think, I didn't plan, i just reacted. It doesn't make me better than you, so if you want the top spot so badly, Bakugo, then take it." She motioned her hand out as if showing off a prize. "Because I know where my priorities as a hero lie."

"Well said," Momo Yaoyorozu murmured from the back of the class and glanced over to her right at Shoto Todoroki. The two of them were the top students to make it through recommendations, and they were already aware of some of what the other could do. "Don't you think so, Todoroki-san?"

"Ah…" Shoto nodded his eyes intent on Izumi even as she took her seat. "It'll be interesting to see if he's got bite to go with that bark." He commented and raised a brow when he saw her pull out a notebook and start scribbling in it. "Who the hell takes notes before a class?"

"That's enough chitchat!" Aizawa, the homeroom teacher spoke from the doorway. He looked groggy and disheveled, and nothing like your typical teacher. After introducing himself he pulled out P.E. uniforms and tossed them at the class. "Let's jump right in, put these on and meet me on the field."

~U.A. Outfield~

It was only the first day and already Izumi was forced to change in the same locker room as the boys. So she averted her eyes, keeping them ahead on her locker or down on the floor. Thanks to Mavis' modifications to the body shaper, its short sleeve design was just right for fitting underneath the sports uniform. Still she felt super uncomfortable, and quickly changed and exited the locker room.

Bakugo paused, his shirt halfway on as he watched Izumi walk out. His lips scowling deep.

"Something's up with you, Deku, and I'm gonna find out what." He yanked on the shirt and slammed his locker closed.

Once outside it was announced they would go through a quirk assessment test. No opening ceremony, no orientation. It was outside the box, which was the appeal of U.A. the school itself followed no guidelines, and the teachers ran their classrooms as they saw fit. For Shota Aizawa, the first day was figuring out if his lot had any true potential to become heroes. Those with no potential, he showed no mercy to, and expelled.

"Midoriya!" Aizawa called out and had her tensing up. Her eyes lifted up and she grunted wondering why she kept getting pushed into the limelight. "You were top score in the entrance exam. What was your highest reading for the softball throw in middle school?"

"I don't know, my sister and I were homeschooled." She crossed her arms, people whispering around her and Aizawa raised his brow. Sighing she tapped an impatient finger along her bicep, thinking about the last time she took an assessment test. "If I had to guess… I'd say around 50 to 60 meters."

"Sounds about right for a boy your size, come then, try it with your quirk." He motioned her over and put her in the circle. He placed the ball in her hand and Izumi stared at it thoughtfully. Izuku had more power than she did, but she wasn't a weakling… she just had to use a full cowl at the highest percentage without hurting herself.

She glanced to her right, seeing everyone watching her and decided…

"Screw it..." Since she was here, she may as well show everyone what she could do. She wound up, her body electrifying with her quirk, hair floating, and muscles bunching. She threw the ball screaming out a roar as she let it fly. Bakugo's eyebrows rose up and his fingers tightened to fists in his pants pockets. He'd seen the quirk before when Izumi had punched him, and watching Deku let loose was almost identical. The two really did have the same quirk.

"Know your own maximum first," Aizawa took a look at the reading and gave a nod of approval. The kid may be small, but he had talent. "That is the most rational way to form a foundation as a hero." He held up the number showing 750 meters. The class all shouted in awe.

"Whoa, you're serious?" Kaminari Denki muttered under his breath. "That's insane."

"We can use our quirks as much as we want!" Sero Hanta said fully pumped up. "The hero course is awesome!"

Awesome, Izumi agreed flexing her fingers as she joined the group again, but difficult. She felt the twinges from using her quirk, and knew she'd have to pace herself and try not to stress her muscles, or she'd just wind up breaking them again like she didn't against the Zero bot.

Aizawa had planned to announce that he'd expel the one who came in last, but seeing Midoriya's quirk had changed his mind. Despite having received the top score, his expectationss had been low because he had also heard the kid had broken both legs and an arm in the process. Someone who got hurt using their quirk had zero potential… but watching the quirk in action, he could see the kid had control. His eyes travelled over the others. He'd make up his mind whether or not to expel someone depending on how the results came out. Those without potential didn't need to be a hero.

"Deku…" Bakugo stepped up to the starting line with Izumi next to him. "Don't hold back in these tests…I'm going to beat every one of your scores while you're at your best."

"This isn't a contest, but fine." Caution forgotten, Izumi let her lips slowly curved in challenge. "We'll see who comes out on top, Kacchan."

"On your mark…" They bowed down into starting position, "Get set," Izumi's back arched up, the line of her body feminine and elegant even with the shaper doing its job. Bakugo's eyes glanced only briefly at her, watching as light traveled from her head to toe. He had an uncomfortable moment of arousal, and that one second of distraction cost him. For as soon as the signal went off Izumi blasted forward ahead of him. He cursed and launched himself forward with an explosion quickly catching up and matching pace as he let his hands explode behind him like jet packs.

"3.95...4.05…" the robot recorded as Izumi pulled ahead by milliseconds. She panted and turned around smirking back at a cursing Bakugo.

"What was that about beating me… Ah!" She ducked a blast snickering as Bakugo chased her around.

"Don't get cocky you little bastard!"

"Is it just me…" Kirishima watched the two run around. "Or does Midoriya and Bakugo have a weird relationship?"

"It's not just you… I can't tell if they're on good terms or bad terms." Kaminari agreed rubbing the back of his head.

"A rivalry between men," Ochaco announced. "One always trying to outdo the other. Both striving for the top! It's a never ending battle." She touched her heart making her words feel more poetic.

"That's so manly!" Kirishima pumped his fist grinning ear to ear. "Alright, it's time to get serious!"

The rivalry between Bakugo and Midoriya spurred on the rest of the class and lit a fire in them. As the two duked it out head to head in each category, the others pushed their quirks to the maximum just to keep up.

Todoroki wiped sweat from his brow as they finished the long distance run, and glanced over at the rivals in question. The more they competed, closer they seemed to get. Though they argued, the two butted heads in a way that was like friends battling in a game. It confused, and interested him. Midoriya interested him.

He wasn't entirely sure why… but the more he watched him, the more intrigued he became. The guy's methods and techniques were interesting, and inspiring. He could see his classmates getting revved up, and felt his own competitive spirit rise in reaction.

When others teamed up to do the toe touches and sit ups he waved a hand motioning Ochaco aside.

"I'll spot you, Midoriya." He knelt down as Izumi took her place.

"Eh? Um, alright… Todoroki isn't it?" She sat and got into position.

"Yes…" He motioned her to start and Izumi closed her eyes breathing as her quirk flowed out and she sat up in a slow and steady pace. "Your quirk is interesting… how exactly does it work?"

"It's…" she breathed and spoke betweens sit ups. "An mmmph enhancer. It amplifies my bodies natural abilities… the stronger I am, the stronger my quirk is."

"I see… so the wind from your ball toss was just the shockwave of your speed and strength increasing?" His grip tightened a little, and his brow rose when felt the slender skin of her calf. "Wow…"

"Wow what?" She paused mid sit up and looked him in the eyes. Because she was sitting up their faces were extremely close. She felt the blush creep up her cheeks when his fingers stroked up the calf, but his eyes remained on hers.

"You've got really soft skin. It's almost like-"

"Oi, oi, oi!" She lay back and started sitting up faster and faster. "Stop getting distracted and keep count! Baka!"

"Right…" he adjusted his grip over her pant leg, his lips twitching and wanting to smile. Yes… Midoriya definitely intrigued him.

~Assesment Results~

"You gotta be kidding me!" Bakugo and Izumi said aloud together as they looked at their results. The two of them had scored exactly the same, and had tied at third place behind Yaoyorozu and Todoroki.

"Well it's not all that surprising considering those two got in on recommendations." Ochaco pat Izumi's back. "Don't worry about it, you still did awesome! It's amazing you and Bakugo got the same exact score."

"Amazing? Try frustrating… I wanted to shut him the hell up." She muttered under her breath and rolled her tense shoulders. She glanced around at the students… then movement caught her eyes. She tensed up and went blue when she Saw All Might and her brother peering around the corner. Izuku was covered up, his hair under a bandana, thick glasses on his face and a hospital mask over his mouth.

"Seriously?"

"Something wrong, Midoriya?" Todoroki asked placing a hand on her shoulder and making her tense up.

"Huh? No, nothing, gotta go!" She quickly ran off towards the corner, her temper raging and she could hear her brother squeak in surprise as she grabbed him by the face and shoved him back before anyone could see them. "Are the two of you insane!? What the hell are you doing here? What if someone sees you?"

"Sorry… All Might and I were doing some physical work ourselves." He motioned to his own P.E. uniform. "And we just wanted to see how you were doing."

"What happened to your wounds? You were in bandages when I left this morning." Izumi looked him up and down.

"Recovery Girl fixed me up… All Might thought I should get in as much training as I can before the event." He flexed his fists grinning. "He's also going to tape all the classes for me so I can keep up."

Then why the hell was she here pretending to be him? She could be the one studying and such and he could be in class dealing with the frustrating Bakugo, the lecturing Iida, and the handsy Todoroki.

"I really hate you both right now." She sighed and stretched out. "I'm taking notes on the class and was gonna give you the details later, you didn't have to come.

"I wanted to see it for myself. You got third place in the assessments. That's amazing, Izumi."

"I was aiming for the top, you numbskull, why is it when I'm not trying to impress anyone I end up getting number one, but the moment I put any effort I'm shoved down?"

"Tis the way of life, I'm afraid. Still if you continued to show no effort your place in the spotlight wouldn't last." All Might spoke wisely and earned a glare from Izumi. Both ihmself and Inko had been very calm and moderate people, where had she learned this temper from…

All Might suddenly got a flashback of Gran Torino punching him in the gut and shouting at him. His face went blue. Oh… that's where.

"I should have just gone with my original plan and tried not to stand out at all. People are gonna notice our differences immediately once we switch back during the sports festival." She ran fingers through the long part of her hair.

"On the bright note, it looks like you and Kacchan are getting along better." Izuku smiled. "I'm glad."

"Just what quirk assessment were you watching?" Her eyebrow twitched. "We were arguing the whole time."

"No… you were laughing too." His smile brightened when Izumi's face lightened. "You were enjoying yourself, come on admit it."

"No way!" She shouted. "I'm only acting like this because I know how you feel about him and I don't want to ruin it for you. So don't get any ideas that the two of us would have any sort of bond because it just ain't happening, Izuku!"

"Deku! Where the hell did you go!?"

"Shit! Come on All Might!" She grabbed the man by the tie and ran off with him in tow so Izuku could deal with his crush. Izuku squeaked and held out a hand.

"Wait, Izu-"

"There you are!" Bakugo crunched his knuckles. "I've had just about enough of your running away!"

"Who's running?" Izuku offered a nervous smile. "At any rate, looks like we tied."

"Tch, the next time won't be so easy." He grabbed Izuku by the chin gripping it firmly. "You've been acting awfully weird."

"What do you mean?" Izuku blinked and tried to keep himself from trembling when he felt Bakugo's grip tighten.

"This hot and cold game you're playing. What happened to our deal?" He shoved Izuku back on the wall.

"I haven't forgotten, Kacchan… but I just thought… maybe you would prefer it like this. Being rivals and friends rather than-"

"I told you it was fine!" Bakugo shouted. "You think I'm an idiot? I know I've got no chance with your sister. She made that point perfectly clear when I saw her after the exam."

Izuku's eyes widened at that. Izumi hadn't told him about that encounter.

"You saw her?"

"Yeah, she was putting flowers by your old building, I thought it was you at first, but I was wrong. I tried walking her to the station and she wouldn't let me anywhere near her. She even punched me. Why is it your sister has more balls than you do… or at least up until now she did. What's gotten into you, Deku? What are you hiding?"

Should he tell him the truth, Izuku wondered and clenched his fists at his side. Should he tell him that the person he'd been arguing with this entire time was his sister and not him?

"It's… hard to explain. All I can say that I may not be acting quite like myself for the next few weeks… I guess you could say I'm trying to figure out who I am." He let out a small laugh. "I'm sorry, but I need you to be patient with me."

"Tch, you're fine the way you are. Don't go changing just because I didn't jump for joy when you confessed to me."

Izuku flinched at that and twisted his fingers together nervously.

"It's not just that… I need to build confidence in myself, Kacchan. I can't keep thinking myself as quirkless. Otherwise I'll never be able to stand next to you."

"What do you think you're doing now?" Bakugo lifted Izuku's head by clucking his chin. "Keep pushing my buttons, keep trying to outdo me… and you'll have to deal with the consequences, Deku."

"Kacchan…"

"You're not your sister… but you sure as hell look like her, especially from the back." He turned Izuku around and pressed up on him. Izuku muffled out a moan and looked over his shoulder. His eyes wet from the sudden arousal. "Maybe if I take you this way… I can pretend you're her."

"Please don't…" Izuku teared. "If you're gonna take me like this… then imagine me, not her. I'm the one that wants it… I'm the one that wants you, Kacchan."

"Fine…" he yanked Izuku by the hair tugging his head back so their mouths met. The kiss hot and hungry and Bakugo's hands rubbed over Izuku's stomach and sides before tugging down his pants. "As promised… I'll fucking kill you."

Briry: Mmmm yaoi, so delicious. Shall we answer some questions then? Oh wait, there are none… Okay so I guess we'll just have to see what happens then.
