(A/N: An Alternate Universe fic, based on Yamada-kun to 7-nin no majo (an AMAZING anime/manga you should read/watch right away)! Although you don't have to have watched Yamada to understand this. The writing's kind of confusing on this, so I'm not sure if I'll continue it, please review to tell me what you thought! Also, in this fic Nagisa and the others are in their first year of highschool

"These scores are abysmal! You should be ashamed!" Mr Kensaku yelled at Nagisa. The blue haired boy lowered his gaze, his blue eyes staring at the floor- He'd failed an exam. Again.

"Sorry, sir." He muttered, his voice low and submissive. His homeroom teacher thrust his exam paper back into his hands with far more force than nessercary.

"What good will apologies do me now!?" Mr Kensaku growled, his voice dripping with contempt. "Because of your stupidity I might not be getting a raise- Get out of my sight you unteachable brat!"

Nagisa didn't need to he told twice- he hurried out of the room with his head bowed low, his eyes still fixed to the floor. He hated this school. He never wanted to go to Kunugigawa, it was an advanced private high school, and Nagisa was only an average student. He could never keep up, but of course, his mother insisted.
In a normal school, Nagisa would probably be one of the top pupils, but here, the standards were insanely high and he was near the bottom of the class, much to his mother's disappointment.

Some second years pushed past Nagisa, sending him flying to the floor- oh yeah, to top it all off he was basically invisible to everyone. There was nothing remarkable about him, he had no presence.

The blue haired boy's books fell out of his hands, he struggled to pick them up as people trampled over them as if he wasn't there.
A girl with green hair picked up one of his homework worksheets, she turned to her friend. "Gosh! Why do people just drop rubbish all over the school? Let me go throw this in the bin."

"Your so diligent, Kaede." Her friend said.

Nagisa got to his feet quickly.

"No! Wait, that's mine!" He cried, but the green haired girl either didn't hear or ignored him, and continued walking to the bin.
Damn! Nagisa was in enough trouble already without loosing his homework that was due next lesson. He started to chase after her.
He recognised the girl as Kayano Kaede from his class; She always acted sweet and friendly, her grades were average but she was always surrounded by friends. But there was something about her Nagisa couldn't trust, she always seemed fake somehow, like her constant smiles were false.

The blue haired boy managed to catch up with her just as she reached the bin.

"Stop!" He shouted, taking a step forward to prevent her from binning it. In his rush, Nagisa somehow managed to trip over his feet, and went flying into Kayano.

Both of their eyes widened in shock, as the two of them both lost their balance and toppled down the stairs together.

Then everything went black.

Nagisa awoke groggily, there was a dull ache throbbing in his head. Slowly, he opened his eyes, and saw that he was surrounded by white curtains on all sides- He was in the infirmary, he must of knocked himself out when he fell down the stairs.
He moved to get out of the bed, his body feeling lighter somehow, when he noticed something terrible-

He was wearing a school skirt!

Had someone changed him into it while he was knocked out as some sort of practical joke? That was messed up!

Nagisa was well aware of his androgynous appearance (The number one reason people spoke to him was to ask him his gender) but this was taking it too far!

He quickly jumped out of the bed, planning to change before anyone saw him like this. He nearly tripped over his own legs- He felt shorter and slighter than he remembered, his body felt weird all over, like it didn't fit right.

"W- What the hell?" He cried out aloud- but it wasn't his voice that he heard. He sounded more high-pitch, more feminine then he was used too. He hair felt longer too. This wasn't right!

Nagisa ran to the full-length mirror in the corner of the room to see what was going on. His heart pounding in his chest, he stared at his reflection, and to his shock, rather than his own sky-blue eyes, a pair of long-lashed golden ones stared back at him.
In the mirror stood a petite girl with green hair pulled up into pigtails on the top of her head. Her eyes were wide and her mouth was agape, but no doubt about it, it was

Kayano Kaede.

"No way.." Nagisa whimpered in Kayano's voice. He was in Kayano's body! It was impossible! This had to be a bad dream!

"Oh, good, your awake." The nurse said, walking over to Nagisa. "How are you feeling?"

"F-fine." Nagisa said on instinct, although he felt anything but.

"Are you sure Kayano-san? You look pale." The nurse said, placing a hand on his forehead. Nagisa gulped when he was addressed as 'Kayano'. He wasn't imagining it then.

"Fine." He confirmed, forcing a smile. No way the nurse would believe him if he told him the truth.

"Well, you better run along to class then." The Nurse said. "The boy who came along with you already went back."

"Boy?" Nagisa squeaked, a feeling of dread pooling in the pit of his stomach.

"Yes- you fell down the stairs with him. Nagisa Shiota I think- "

Nagisa was out the door before the nurse could even finish speaking.

If he was in Kayano's body, that means Kayano was in his body! And now she was walking around pretending to be him!
Nagisa ran to class faster than he ever had before, and swung open the door, barging in.

"Ah, Kayano-san. Glad to see your feeling better." Mr Kensaku said, directing a smile at Nagisa- It was so weird being spoken to kindly by this man who normally loathed him and wasn't afraid to show it. "I hope you weren't hurt too badly by Shiota's stupidity."

Nagisa didn't bother responding- he scanned the classroom, his eyes resting on the blue-haired boy sat as his desk.

It was him. Or rather, it was Kayano in his body. It had to be- It was so strange seeing himself from a third person point of view. His body was sat legs crossed like he was wearing a skirt, with a vapid smile that the real Nagisa would never wear. She'd changed his hairstyle too- instead of being in it's usual limp ponytail, Kayano had pulled Nagisa's long blue hair up on top of her head in pigtails.

What the hell was Kayano thinking? going back to class like nothing was amiss after they'd swapped bodies!

"You can take your seat now, Kayano-san." The teacher said. Nagisa glared at Kayano, trying to catch her eye. She just looked at him and smiled, putting a finger to her lips.
He was left with no choice other than sitting down in Kayano's chair near the back of the classroom. He was still too disorientated to formulate any kind of plan.

"Kayano-Chan, are you alright!" A girl behind him squealed as soon as he sat down. Nagisa turned to see Touka Yada smiling at him.

"We were worried that you'd gotten hurt." Yukiko Kanzaki, the concern in her soft hazel eyes seemed genuine.

"I'm fine." Nagisa said, telling that lie for the third time that day. In truth, his mind was racing and his nerves were in a frenzy... How was he suppose to act like Kayano and pretend everything was normal?

"Are you sure? You seem kind of out of it." Yada said,

"I'm fine, really." Nagisa said, trying to be more upbeat like the real Kayano was. He couldn't help but feel a slither of jealousy towards the girl who's body he was currently inhabiting; It must be nice having friends who care about you.

"Now girls, today's an important lesson, so no talking in class, okay?" Mr Kensaku chided lightly. He was so much kinder to students who got decent grades.

Nagisa spent the rest of the lesson on edge, constantly stealing furtive glances at the clock, praying the lesson would end quickly so he could confront Kayano. He kept glancing at her- seeing somebody else in his body was like an insane nightmare (He had no idea that he looked that much like a girl.)

When the bell rang, Nagisa shot out of his seat like a bullet, and rushed over to Kayano.

"We need to talk Kay- I mean, Nagisa." He said, looking up at her, frowning- Nagisa was used to being short, but not this short, Kayano's body was easily the smallest in the class. Kayano smiled at him.

"Okay, Kaede." She said seamlessly- she was far too calm for this situation! The two of them walked out together, ignoring the confused glances they got (because why would a popular girl like Kayano be seen dead with a nobody like Nagisa?).

"Okay! What the hell is going on?" Nagisa yelled once they were on the roof together. Kayano laughed.

"We swapped bodies, duh!" She said, clearly amused by the situation. "Why do you wear clothes that are like, two sizes too big by the way?"

"I bought them thinking I'd grow into them- Stop changing the subject!" Nagisa said, exasperated. "Just- How did we swap bodies? And how do we swap back?"

"Hmm, if I had to guess, we swapped bodies by falling down the stairs together, and we can swap back by doing the same thing again." Kayano said, twirling a strand of blue hair between her finger-tips.
As if this day wasn't crazy enough without magic stairs being thrown into the mix.

"Quick! Let's go do it again now." Nagisa asked eagerly. He had no idea how that could be scientifically possible, but at this point he'd clutch any straw. But to his surprise, Kayano shook her head.

"No can do, sorry!"

"What!?" The boy trapped in a girl's body cried. Was she insane?

"If we fall down the stairs we might get hurt or knocked out again, it'll be weird if we have to go to the nurses twice in one day. People might notice somethings up." Kayano said. "Besides, today's lessons will be on the test so I don't care what body I have to be in, I'm not missing them!"

Was this girl seriously so dedicated to learning that she was willing to work in these kind of conditions?

"Maybe if I had that sort of resolve I wouldn't be failing class." Nagisa said sardonically. Kayano giggled.

"Don't worry, we'll fall down the stairs together and change back after class." She said. It was weird to see such a cheerful expression on his own face.

"Are you sure you don't just enjoy being inside my body?" Nagisa asked, raising an eyebrow. Kayano shook her head.

"No way! There's something weird between my legs, I can't sit comfortably at all!" She complained. Nagisa felt his face redden as a blush spread across his face.

"W-well you don't have to broadcast it!" He spluttered. A sly grin suddenly grew on Kayano's face.

"What about you? Is it weird being in a girl's body? Does your chest feel heavier than your used to?" She asked, Nagisa shrugged.

"It's weird being this short, but my chest feels the same as usual." He mused. Kayano's eye's flashed with anger.

"Hey! I'm still growing, okay! You asshole!" Kayano yelled at him- that was a surprise- he'd never seen her pissed of before, her default mode seemed to be permanently happy and bubbly. Looked like he'd hit a sensitive spot.

"S-sorry." He muttered, as the bell went. Kayano was still pouting as the two of them walked to class. They still had four hours left till the end of school, and Nagisa knew the wait would be torture.

"Kayano! Were did you go all break?" Yada asked, hugging him as soon as he entered the classroom. Nagisa stiffened not used to physical contact.

"I- just went to get juice and got lost." Nagisa lied, to his relief, the brown haired girl laughed.

"Oh- that is so like you, Kayano!"

"So, what was it that you were talking about with Nagika?" Okano, a short-haired girl with an athletic build asked.

"Oh, nothing." Nagisa said. Did they seriously not know his name?

"You sure you weren't confessing your love to him?" Yada teased,

"Well, Nagisa is cute." Kanzaki said,

"Yeah, a little too cute for a boy." Okano said, frowning.

"What's that suppose to mean?" .

"You know- it's not fair for a boy to be that pretty." The short-haired girl said with a sigh- she almost sounded jealous. Nagisa had to resist crying out 'I am not pretty!'
It was going to be a long day.

Lunch time rolled around all too slowly for Nagisa's liking. The lessons dragged on, and every minuet felt like an eternity. He didn't care if it was small, weak and girly-looking, he wanted his own body back, dammit! He had spent most of class time just staring at Kayano's hands. It was so surreal, seeing someone else's hands. Her's were small and pale, she had multi-coloured bandaids across her fingers.

"Aren't you eating, Kaede-chan? You've been spacing out all day." Yada said to him, as he sat around the table with Kaede's friends.

"Sorry! I was just focusing super hard on lessons because it's coming up on the test!" He said, he glanced over at Kayano; She was sitting eating lunch alone like he almost always did (since his closest friend Sugino had baseball practice at lunch).

"Yeah, man, Mr Kensaku is such a slave driver. We get tests so often, I can hardly keep up!" Okano complained, the other girls nodded in agreement.
Nagisa reached into Kayano's bag and pulled out her lunch box (Bright blue with a flower pattern). He felt somehow guilty eating it, but Kayano was doing the same thing with his, so what the hell. He opened it-

"Wow- cake again? How do you eat so much and stay so tiny! I just have to look at sweets and I gain ten pounds." Yada complained. Nagisa laughed awkwardly, not sure what to say. He picked up a slice of the brightly iced clearly home-made cake. His eyes widened when he saw what was underneath;

Squashed beneath the cake was a huge cockroach, it's dead legs pointing up into the air.

Nagisa wasn't a squeamish person, but the shock made him drop the cake in his hands.

"Kaede, what's wrong?" Okano asked. Before Nagisa could formulate a response, Kayano (in his body) was suddenly stood behind him.

"Kaede-Chan, you said you would help me with the maths formula at lunch, could you come with me to the library for a moment?" She asked, putting a hand on Nagisa's shoulder.
Though still shaken up, the boy took the hint. "S-sure." He said, he turned to Kayano's friends. "Wont be long- "

"So why was there a cockroach in your lunch box?" Nagisa asked, somewhat sheepishly once they were on the roof. Kayano sighed then smiled, but Nagisa could tell it was forced.

"I don't know- it must of been a practical joke."

"You seemed to know about it before I did, you zipped straight over."

"People play jokes on me a lot."

"Kayano.. Are you being bullied?" Nagisa asked. He raised his hand and looked at the bandaids on Kayano's fingers. Hiding razor's in their victims books was one of the tactics that bullies at Kunugigawa often used.

"It doesn't matter, they'll get bored soon." The girl said, still smiling. Her expression looked unnatural on the blue haired boy's face. Nagisa frowned- So even somebody as cheerful as Kayano had problems?

"Have you told anybody? Your friends? The teachers? They can help- "

"Absolutely not." Kayano cut him off with uncharacteristic sharpness. She no longer wore a smile on Nagisa's face. "To my friends and everyone at this school, I'm the upbeat, cheerful girl who's kind of a ditz but is nice to everyone!" She said, grinning almost theatrically and gesturing. "Being a bully victim just doesn't suit my role- I can't let negativity mar my performance! So of course, I can't let my friends or anybody know, and you're not going to tell them."

Nagisa stared at her, shocked- He always got vibes that Kayano could be fake, but she was acting almost all the time? That seemed lonely, somehow.

Before he had a chance to respond to her, a tall, carelessly handsome boy with red hair strolled out onto the roof, a juice box in hand. The top few buttons of his shirt was undone, and he was wearing a black blazer that definitely wasn't part of the uniform. He was Karma Akabane, a boy in their class who was always skipping.
"Hmm- this is the first time I've ever seen other people in my spot." He mused, a half-amused smile on his face. "Sorry if I interrupted a make-out session or something."

"W- we weren't doing anything like that." Nagisa said shyly. Most of the school was terrified of Karma, but Nagisa had always admired him; He did what he liked, when he liked, and he always seemed to cruise through life with ease, winning fights and getting insanely high in exams without even turning up to class.

"Whatever, I'm taking a nap out here so don't wake me up." The red head said, shrugging his shoulders. "Nagika and Kayano, right?"

"Nagisa!" The other boy corrected, frustrated- Why The hell did the entire school think his name was Nagika?

"Okay, fine- sorry I got your boyfriend's name wrong." Karma chuckled. Shit! Nagisa in the heat of the moment, He'd forgotten that he was in Kayano's body and not his own!

"I-It's fine." Nagisa said, embarrassed.

"We're not a couple!" Kayano reminded just as the bell went for the end of lunch.

"I guess you're not coming to class, Karma-kun." Nagisa said, as he turned towards the staircase off the roof.

"Not even if you paid me." The red-head said, opening one eye to look at the two of them. "You two good kids should run along now."

"I wish I was as smart as you and didn't have to study to get good grades." Nagisa sighed wistfully as he opened the door. Karma looked up at him, raising an eyebrow. "And you can win any fight too, it seriously isn't fair how some people get to be geniuses."

As soon as they were in the stairwell, Kayano grabbed Nagisa by the shoulder's and pinned him to the wall.

"What the hell was that!?" She cried, clearly annoyed. Nagisa was confused.

"What was what?" He asked. It was actually kind of intimidating being grabbed by someone when you were in a body as small as Kayano's. His own body seemed to tower over him.

"Okay I get that you have a crush on Karma, but flirt with him in your own body! Now he's gonna think that I have a crush on him!" She cried, incredulous. Nagisa felt his face heat up.

"I do not have a crush on Karma! And I wasn't flirting!"

"Pfft- you were all 'Karma, you're such a genius, let me kiss you'"

"I said no such thing!"

"Gah! Now he's going to think I'm some pathetic girl who's after him!" Kayano whined, then suddenly looked horror struck. "Or worse! What if he gets a crush on me? I can't be with a scary delinquent, that definitely wont go down well!"

"Aren't you over reacting?" Nagisa said, his face still red, trying to calm her down. Suddenly, the door onto the roof opened revealing Karma, he looked down at the two of them, raising and eyebrow.

"Hey there, 'not couple'. " He said as he walked past them down the stairs, his lips curling up into a half smirk.
The two of them jumped away from each other, realising the position they were in; Kayano was pinning a blushing Nagisa to the wall. But of course, from Karma's perspective, it appeared to be the other way around.

"Had no idea you were so rough with your women, Shiota!" The delinquent said as he skipped of the last step, walking away before the two of them had a chance to explain themselves.
God dammit!

The last few hours of school seemed to drag even more than the ones leading up to lunch. Their ageing teacher droned on about history, and as usual Nagisa found it impossible to listen. He always had problems focusing in classrooms, he was the observant type and found it difficult to ignore all the little distractions in the classroom;

The teacher had a blob of yellow curry on his white shirt again,

The air conditioning was making a rackety sound

Terasaka and his gang were skipping class again, he could see them leaving the school gates from outside the window.

When the bell finally rang for the end of school time, it was beyond a relief. Both Nagisa and Kayano
bolted up straight away, eager to leave and get back into their own bodies. Nagisa said a rushed farewell to Yada, Okana and the rest of Kayano's friends before hurrying out of the classroom to the stairwell were it all began.

"This is it." Nagisa said, looking down the steps. "You sure this will turn us back to normal?"

"No, but there's only one way to find out." Kayano said grimly. The two of them stood there for a moment next to each other, before swallowing their apprehension, falling forwards, purposefully tumbling down the stairs together.

Crash!

Bang!

Nagisa felt a pain spread across his head- had it worked? He looked at his hands; They were still Kayano's small bandaid covered ones.

"What the hell! It didn't work?" Kayano cried, dusting herself off and standing up. "What if I'm stuck in this body forever?"

"Maybe it'll wear off in time?" Nagisa suggested half-heartedly. He just wanted to get his own body back.

"I know!" Kayano said, sounding triumphant. "Maybe we need to fall down the stairs in the same way we did last time! You need to barrel into me while I'm near the bin!"

Moments later they were at the top of the stairs, still smarting from their first fall.

"Kayano, are you sure this'll work?"

Nagisa said, as he stood behind her.

"It has to work! I can't think of any other ideas!" She said sounding desperate, her currently-blue eyes wide. She was stood next to the bin, ready to be pushed down the stairs again.

Nagisa repressed a sigh; This was the stupidest plan for the most ridicules situation he'd ever been in. He couldn't help but feel like an idiot standing here preparing to fall down the stairs for the third time that day.

"Okay, now go!" Kayano demanded. Nagisa awkwardly took a step forward, still feeling like a fool then threw himself into her, so they both went plummeting down the stairs.

Crash!

Nagisa opened his eyes, only to find himself inches away from his own face- He still wasn't inside his own body!

"Enough! I'm out of ideas, I just want my own body back." Kayano said, her voice quiet and defeated. Nagisa felt a pang of guilt, feeling somehow responsible. He hated seeing girl's upset (even if her body wasn't currently female).

"..I have an idea." Nagisa said after a pause. Kayano looked at him, eyes filled with hope. "When we fell down the stairs the first time, our lips touched. We accidentally kissed."

"W-we did?" Kayano said, a blush spreading across her face. Nagisa felt his face redden too, embarrassed by his next words.

"M-maybe if we do it again we'll change," He said, flushed.

"You mean kiss again!" She cried- Kayano seemed genuinely shy about this stuff, Nagisa had no idea she was so pure. He nodded.

"We'll just do it once quickly." He said, leaning forward on his hands. Kayano hesitated for a moment, before nodding. Nagisa closed his eyes (because it looked like he was kissing himself, and that was just too weird) and kissed her, in a very chaste innocent way.

He felt a flicker like a TV had been switched on. He opened his eyes and found himself inches from Kayano's face- The actual Kayano, with her golden-hazel eyes and green hair, a blush across her cheeks.

"It worked!" Nagisa said, more relieved than happy. A smile spread across Kayano's face too.

"I don't care what crazy magic-science caused this.. We're back!"
The two of them both stood up cheering, ecstatic to be back in their respective bodies.
They didn't notice the pair of mercury eyes watching them from inside one of the classrooms.

'Interesting' Karma thought to himself as he watched them head home, his lips curling up into a devious smile.

A/N: I don't normally make first chapters so long! So if you made it all the way, well done. I hope the writing wasn't too confusing (Since the whole body-swapping thing), If you think I should continue, please review :3
