AN: WOW. I WROTE AN ACTUAL FANFIC INVOLVING THE MAIN CHARACTERS THEMSELVES. NEVER THOUGHT I'D SEE THE DAY. Came up with this based on the Osgood principle from Doctor Who that she is neither Zygon or human. It's a lot like Steven Universe fusion, but hey SU is awesome. Can be seen as Rokusora, but personally I just see them as really great friends who maybe just hug occasionally. The cover is by Renrink who does amazing Rokusora, Undertale and Puzzleshipping stuff on her tumblr. Enjoyyyyy.

Kairi wondered if she looked hard enough she'd see him. The boy that always danced around her thoughts and the boy whose smile brightened up her whole world. The boy who'd saved her life on more than one occasion.

It was the little things at first.

The changes in speech pattern, unnoticeable. But overtime, came up in everyday chatter. Kairi maybe gave him a confused look, nothing too obvious. People slip up from time to time. Her friend was still him. She'd always smile and tell him kindly and he'd always get that flustered smile and look at her with big ocean blue eyes. She'd look into those shimmering sapphires and remind herself that it was just nothing.

Then, it was the behaviour. He'd seem to get a tad bit faster to anger, his fists would clench a little, his eyes would narrow a little sharper and she could see those tiny details. His knuckles would then relax and she'd convinced herself it was nothing. It should be nothing, right?

Then, it was his appearance. She could see it, the tiny specs of blonde on the edge of his chocolate spikes. His skin was less darker too, some of that usual beach tan fading under the blistering sun. He'd be meeting her and his friends later and later, his sleep schedule progressing into a longer period. These details were too glaringly big to her, that she couldn't shrug it off any longer. In her mind, she convinced herself something was wrong. But in her heart, she was too afraid to face the truth.

What… what is happening…

Sora thought to himself. There was something strange happening to his heart. He could feel it, a hole being drained and constantly filled at the same time. It all started after Roxas gave him all his memories. It was like the memories were constantly traveling back and forth between the two souls, a mix between the two person's memories. It seemed that the memories couldn't decide where to stay so they were always trading places.

It sent his mind in a whirl. The memories were affecting his behaviour among other things. He could feel it, the aching.

Roxas…

Sora's heart called longingly out to his nobody. Obediently, he came and stood in front of Sora on the station of serenity.

"So, you feel it too, huh? My heart is… yearning for something." Roxas asked, placing a hand on his own chest. The words echoed in Sora's head as if he somehow had guessed his Nobody was going to say that. "But, you already knew that." Roxas replied.

Ever since this whole mess started, Sora could feel Roxas stir inside him more often. His constant waves and ripples had stopped in the World That Never Was, but after the mastery exam, those waves had started up again, day by day becoming more restless like a tsunami.

Sora's heart seemed unsatisfied with how things had gone with Roxas, and Roxas after truly becoming okay and accepted his terms, still had that rebellious seed deep inside. Now, it seemed they would come to face these emotions, the longing they felt in their hearts.

Sora bent over in pain as his eyes suddenly stung. Everything became blurry and the lines unmatched. When he looked up, everything was disconnected and the figure known as Roxas, started to look like a reflection of himself. It was like that for a few moments until his nobody's voice cut through his thoughts. "Sora?!" He said. "Are you alright?"

"Y-yeah. I think." Sora responded, still clenching his head with his hands. Then the pain came again and both of them mirrored each other's movements of agony. Their hearts were crying out for each other and they wouldn't stop screaming.

Suddenly, their eyesight went black. In the darkness, they could still hear each other's breathing, until it seemed it was insync. The pain died down inside them and they opened their eyes.

Everything was muddy for a few moments, but then when their vision stabilized, the other was gone. Not seeing their other, they panicked and called out their name! "RSoxras!" Their voice called out.

Surprised, they covered their mouth with a swoop of their hand, eyes widened. Confusion swept over them.

What's going on? Sora?

What's happening? Roxas!

Their thoughts overlapping inside their head. They looked down to see their mismatched outfit, it was as if the two had merged. Their hearts… had become one. Well, not exactly. It seemed that it was still dysfunctional. They still had a tiny bit of the separate entities lingering.

I think we need to calm down.

Just what is happening?

S… Sor…. Sora… you're not helping.

Did you just forget my name there. Did you.

I'm sorry, it just slipped!

Names don't just slip, R… Rox… Roxas…

See?!

Well at least when we were in castle oblivion there was a reason we forgot names. Namine was messing with our head.

S… so… so…ra... Sora, I wasn't in castle oblivion with you. We were at the Organization 13 headquarters.

No we weren't. Um, what's your name again?

I'm… That doesn't matter! Yes we were, ... m...me.

I'm… not… you… R…o…

We're not getting… I'm not... getting anywhere, are I?

No... we are…not.

I... should... just rest...

They curled up on the floor, eyes dull and distant as the two distinct voices faded. His eyelids drooped into slumber as they he heard the faint echo of the two voices slowly combine into one.

Sora's eyes shot open in the morning sun gazing through his window.

Just a dream…

He thought to himself, with a smile. After the Mark of Mastery exam, strange dreams would not be on short supply, so he wasn't sure why this particular one would be so shocking. It was all so foggy, he couldn't remember why he was so scared in the first place.

Sora looked over at his clock to see he had slept in later than usual. Of course, it was a saturday, so he assumed it was only natural. He yawned and stretched his arms as he sat upright. For a few moments, his eyes stared off into space as he collected himself. Riku! Of course, he was supposed to meet Riku!

He jumped out of bed and scrambled to his closet. "C'mon, c'mon." He randomly grabbed whatever clothes in reach and put them on. After nodding at his reflection in the mirror, checking his outfit was still somewhat presentable, he shook his hair and ran downstairs.

Sora dashed into the kitchen, his mother sipping on a cup of coffee. She happened changed at all these past years, still the same kind woman that always packed him a few extra cookies in his lunch box. "Good morning- Sora," His mother said, chuckling at his appearance "what are you wearing?"

"Oh, well, I'm kinda in a hurry, but I can go change." Sora replied, stopping dead in his tracks. His mother smiled and shook her head. "No, it's fine. I know you're late for a very important date. I'm sure Riku won't mind." She said. Kairi might get a good laugh, though she thought. She took another sip of her coffee as Sora kissed her on the head.

"Love ya." He said, before rushing out the door.

"Sora! You're late!" Riku yelled out to him, waving from the far distance of the shore. Sora came running up, gasping for breath. "S-sorry!" He said between breaks. Stopping, he leaned over on his knees. "I came as fast as I can."

"I can see you were in a hurry," Riku said with chuckle "no wonder you look so mismatched." Sora stood up straight and looked down at himself. He was wearing a usual red jacket over a vest, with white baggy shorts down to below his knees. His shoes were also different and he seemed to be wearing a wrist bracelet with a checkered pattern. Seriously, when did he ever buy that?

"Hey, I tried my best to be on time. At least level with me here!" He said with a frown akin to a child and crossed arms.

"I would, but then I'd have to bend down to match your height." Riku laughed and Sora punched him playfully in the shoulder for the remark.

"Where's Kairi?" Sora asked. He looked down the side of the beach to see nothing but the smoothly crashing waves and endless sand.

"She said she had an errand to run before hand. We'll meet up with her later. She told us yesterday, remember? Man, you have not been on your A-game lately, have you Sora?" Riku said jokingly.

"Yeah, okay, sorry." Sora said, turning his eyes to the ground and absentmindedly kicking a little bit of sand with his hands in his pockets. His mind wandered to the dream he could not remember last night. He could definitely feel his heart aching in it's search to remember.

"Um… Sora… is everything alright?" Riku asked, his tone more serious than before. Dang it, how did he always know when something was up? Sora looked up and put on one of his reassuring smiles.

"Of course, Riku. And you say I'm a worry-wart." He said with a laugh, trying hard to sound convincing. In his mind, he pleaded his friend would not notice.

"Whatever you say." Riku said with a smile, messing up Sora's hair and shaking his hand through it.

"Hey! Stop!" Sora said, useless to try and stop him. Riku stopped for a moment and frowned. Sora's laughing died away as he noticed his friend retract his hand. "What's wrong, Riku?" He asked, raising an eyebrow.

There it was.

Under all that soil brown hair.

Blonde roots.

Riku pretended not to notice as he quickly smiled. "Nothing." Surely it was just a trick of the light, right? Sora was still Sora.

Sora!

He heard the blonde nobody call out his name, the voice echoing in his head. He tried moving, but found he could not, so he stayed planted face first on the ground.

Roxas? What's going on?

Sora called out into the abyss of his mind. Suddenly, he remembered yesterday's dream and started to panic. His heart started to race as he could feel their body going numb.

Sora, calm down, if you keep it up, we're going to-

The nobody's voice was cut off, as the heart suddenly split into two and the two boys unmerged.

"...Separate." Roxas finished, bouncing back onto the floor. "What the heck just happened?" Sora asked, scared. He was confused and flustered and frankly, all over the place.

"Well, it seems our two hearts became one heart instead of mine merging with yours, and you reigning dominantly over the two." Roxas explained the best he could. "It only happens when our hearts are in sync, though, so if our emotions don't line up, we split apart. It's also the reason we couldn't move: you wanted to, but I didn't."

"But… why?" Sora asked, calming down. The whole matter seemed odd beyond Sora had even heard of, but it had happened, so it must've been real.

"I don't know. But you feel it don't you? It's happening again." Roxas said. Sora focused on the emotions dwelling within him. Deep inside, he could feel it, his heart rate was changing again. "Look. Why do you have my wrist?" He asked.

"Huh? I don't have your…" Sora's voice faded as his fingers were on Roxas wrist, the veins connected to his heart. He could see now that Roxas was mimicking the motion with Sora's own wrist. It seemed that they were measuring each others heart rates. Sora's nervous eyes looked up into Roxas's sapphire ones that were so much like his own. He could see sweat start to go down his nobody's face as Roxas's heart persistently tried to beat as fast as his own frightened heart.

That's when everything clicked into place.

They both let out a yelp of pain as the two hearts slowly merged together once again, the two souls intertwining and appearances blending. Sora could feel his heart - or was it Roxas's? - slowing down, the fear fading as his eyesight tried to stabilize. When everything had settled, a feeling of pure bliss washed over their heart as it beat contently in their chest. The emotion couldn't help but make them smile.

Woah.

I know.

Now how do we move again? Oh right.

See? You already know what I'm going to say.

Their eyes fluttered open as they tried to look around. The Station of Serenity was a weird mix of Roxas and Sora's, the blue sky and twilight slowly mixing together. Sora tried to move right, but his other prevented him from doing so. Sora sighed mentally. Moving was going to be hard.

Let's go right.

But what about left, that's where I am.

Why not me though?

You've had your own body for some time, at least give me some chances.

You know I couldn't help that!

Fine, why not at least stand up first?

Sora didn't argue as they put their knee up and pushed themselves onto their feet.

That wasn't so hard.

I sometimes wish you weren't so optimistic.

I'm sorry, I can't help it.

Their heart slowly skipped a beat and they could both feel it. It was impossible to hurt each other because it was like hurting themselves. It's harder to inflict pain if you feel the same thing as the person you're inflicting it on.

Well, maybe some of that optimism will rub off on me. In this state, we do have the same heart.

You never know, anything could happen.

I can't see it going any other way.

They hugged their chest and held their side arms, laughing. They abruptly stopped. "Did we just do that?" They said, voices in sync.

I guess we did.

They smiled, thoughts perfectly aligned. Their heart radiated glee as laughter coursed through them like liquid sunshine. Roxas wondered if this is what Sora felt like, being so happy everyday, always being able to see the bright side of everything.

These thoughts muddled everything up and Sora could feel himself rippling, finally disconnecting again.

"Roxas? Is everything okay?" Sora asked with concern. Roxas shook his head, saddened by his own train of thought. Sora walked over and stood in front of him. He looked up into his other's eyes and could see the tears forming in them.

"No. Because… this is just a dream. You're going to wake up with no memory of this, and I'm going to sit here, all alone again. This isn't the first time we've done this! We've done this many times, but you always forget and we end up splitting apart! You're always so happy, and able to see beyond the storm. I can't do that… I'm more sharper and angrier than you and your gentle hands will ever be." Roxas said, trying to shy away, trying to run so far, that no one could find him and he could hide his weakness. But his heart refused to let him and his feet stood planted on the beautiful stain glass floor.

"Roxas… when we're connected like that… I know you think that it's just me, that you're an addon, but you said it yourself: Our form only works if our hearts are the same. Those happy emotions couldn't have been all me, but also you. Our heart can't shine brightly if we're both not willing to let the light in. Roxas, you're not just a dream to me…" Sora said, wiping away the tears of his nobody, partner, other, his... "...you're my friend."

Roxas stopped crying to see the tears in Sora's eyes, showing how sincerely honest he felt. Not able to take the separation any longer, Roxas hugged Sora, much to his surprise. His other was always so warm and gentle, and Roxas let himself get lost in that feeling as Sora put his arms around him. The two hearts resonated and slowly merged into one, all their feelings getting mixed up in their souls, until all that was left was the one being in their place.

They just sat there, the silence not empty, but full of comfort. The feeling of being safe and sound. The heart was finally at peace.

Hmm? What's going on?

He thought. He slowly sat up in bed and looked around, the room still in a daze. After a few blinks, he shrugged it off and sluggishly got out of bed. After his feet made contact with the warm carpet floor, he pushed himself up and slipped on his bunny slippers.

He yawned and put a hand over his mouth. The smell of morning breath rushing through his nose, almost startling him. Yikes.

Bathroom.

He agreed, nodding. He made his way towards the door and turned the cold metal knob. He shuffled his feet across the hallway to the bathroom and pushed it open, whispering a quiet bit of triumph under his breathe. Good, it wasn't occupied. The fact in of itself he hadn't bumped into his mom on the way here had been a miracle, she'd surely be unhappy with how unkempt he looked.

He picked up his blue toothbrush and squirted the toothpaste onto the thistles. He raised the toothbrush to his mouth and looked up into mirror…

and immediately dropped it into the sink.

He widened his big blue sapphire eyes at what was reflected in front of him. Sure he looked like Sora, but at the same time, he looked like Roxas. His hair was like big floppy leaves, darting in different directions and sticking up in some places. It was undoubtedly brown, but the bright blonde roots spawning from the middle of his head had grown to a much bigger degree. This was the first time he'd ever seen them in this form.

He put his hand on his cheek and then pinched it. "Ow!" He let out a small yelp of pain. Yep, this wasn't a dream and this was definitely him. Hopefully he didn't wake his mom with that test.

He looked both left and right, as if confirming there wasn't some ninja in the bathtub. He then leaned on the sink and pressed in closer to the mirror. "...Sora?...Roxas?" He whispered.

Yes?

He answered in his thoughts. He looked down at his chest, his heart beating a smooth happy pace, his fear being pushed down by undoubtedly Sora's optimistic half, and filled with an odd soothing wave, Roxas probably expressing his content to stay the way they were. And from the amount of synchronization the one heart was radiating, the two hearts weren't going to separate anytime soon.

Why did we stay like this?

He thought, the two voices overlapping and flowing together inside their head. The sound of his own voice was happiness to his ears, the two hearts hearing the other's voice and smiling.

If we're going to get any answers, we should probably stop this.

He thought with a sigh. He closed his eyes and they could feel the other heart slowly coming into focus, the two heart beats becoming more different, but still the same heart as he stood stiff like a zombie in the bathroom.

Sora!

Roxas!

Okay, what did you want to talk about?

As much as I like this, what about Riku and the others, wait, forget them, what about OUR MOM. She's gonna freak if she sees us!

Just calm down, won't they accept us the way we are? Riku turned into the appearance of one of

your worst enemies and you and Kairi still liked him.

Well, I know they accept me, but… you're a different story. And last time I checked, you didn't really like Riku all that much.

But, I don't want to be away from you.

Sora could tell from where his nobody was coming from, his own heart all too pleased to stay this way.

Please, just let me talk to them first.

… Make sure you don't forget about me.

The one heart slowly separated into the two hearts and Sora could feel total control slipping back into his grasp once more. By the time he could barely feel Roxas, he could see his appearance had gone back to normal. He gave himself a shake, trying to readjust to the feeling.

His heart ached for his other, the emptiness Roxas used to fill causing him pain. Sora pushed that feeling down. He needed to think of a plan.

"Okay, be ready." Sora said and closed his eyes. His heart called out for his Nobody and Roxas obediently answered, the constant prescience growing stronger. The walls he had put up were torn down and he could feel Roxas jump into his heart's outstretched arms. The two hearts slowly merged into one and Riku and Kairi could see Sora change before them.

His blonde roots conquered more of his brown hair, whose spikes dulled down to part in different directions. His face changed and shifted a bit.

He opened his glimmering eyes to their astounded faces. "Hi." He said with a small wave.

Riku got on the defensive side. "Which one are you? Sora or Roxas?" He said more like a demand than a question.

"I'm Me." He responded simply. The answer, unsurprisingly, did not please his friend.

Kairi looked him up and down. She bit her lip, and gently put her hand on Riku's arm trying to keep herself steady. She turned her violet eyes to his, and shook her head, discouraging his attitude. "Do you have a name?" She asked, turning back to him, certainly more kind than Riku.

But... We don't really have a name...

He thought inside his head.

"My name is Sora... Always has been, always will. But you can call me Hikari if you want." He said, flashing his signature smile and putting his arms behind his head. The "real" Sora was surprised, because it was Roxas who had suggested the idea.

I guess Roxas is just an anagram of Sora with "X".

Hikari thought.

Kairi and Riku were exchanging unconvinced glances. "For how long has this been going on? More importantly why?" Riku asked.

Technically, they had been one heart for quite some time, but Sora's heart and soul reigned dominantly over Roxas's heart unequally. Sora after realizing this, always had wanted Roxas to be his own person, a life of his own. After their two hearts had truly merged, both person had an equal control over the body. When they talked, it was always in rhythm with the other, a bond of complete trust over the other's actions. There was no Sora or Roxas anymore in this state.

Their minds and heart were one, forming almost a completely new being.

He hugged his shoulders over his chest."We feel more comfortable this way… almost making sure we never feel alone again." The fusion said, pacing his words carefully.

Riku still took a deep breath, trying to process this. "You said 'we', but you also said your one heart?" He asked.

"I'm both of them, just merged into one. Two hearts just beating to the same rhythm. I'm Roxas, but I'm not Roxas, I'm Sora, but I'm not Sora..." He said confidently.

"So you can change back?" Riku asked. Obviously, he could weave in and out of both forms, but the details were kinda fuzzy.

Hikari nodded. "Uh-huh." They were silent for a few moments until Riku made a go on gesture. "Um... We kinda can't right now. To put it simply, we're too comfortable like this. Problem?" He said, his face frowning a bit. Riku agreed silently that that line definitely had come from Roxas. The thing that confused Riku though, was that Sora had let him say it.

"I still have all the same memories and feelings though. That'll never change." Hikari said. "But I've promised to remain the true Sora most of the time."

Slowly, the one heart started to separate, at first refusing to do so. Until finally, the heart reluctantly split into two and Sora's appearance changed back. He bent over on his knees and coughed up blood from the action.

"Sora!" The two friends rushed over in surprise. His body rejected the transition, causing pain to course through him.

"My heart... Prefers to be that way." He said, standing up and wiping the blood from his mouth. His heart was in pain, ripped from his others arms causing it to gush out in agony.

"Could I please... Go home..." He started to stumble. Then his face hit the warm sand and everything went black.

He sat up in bed, gazing at the night sky through his window, his heart merged contently. In this state, he tended to heal faster, the power of two hearts working away to heal one. He clenched and unclenched his fist. He also felt stronger and was faster this way. Everything was improved when Sora and Roxas were in harmony within him.

He looked down at the heart beating away in his chest. It was full of warmth and love, the feelings the two felt for each other constantly humming away peacefully. That's why he was always so happy, surely the two expressing their content for being together the way they were. Sometimes, when they weren't voicing his own thoughts, he could hear the two voices whisper the other's name affectionately, as if making sure the other would never leave.

He layed down and closed his eyes. It seemed whenever their heart wasn't focused on his senses, they would be able to talk to each other. They slowly let go of their limbs and he rested his head back as he fell into sleep.

What exactly happened today? Sora's voice rang out.

I didn't know changing back would hurt you, would hurt us. Roxas responded

Well it's definitely something we need to work on. It didn't happen the first time.

Why did you even want to separate?

Because Riku asked.

Ha! So, you're everybody's puppet now?

There's a difference between order and request. Riku's my friend.

Their body curled up, putting a hand to their chest, the small bickering causing a few ripples in their connection, the form wavering.

Why are you so quick to trusting everyone? Anyone could betray you at any moment.

Huh? Why would they?

What do you mean "why"?

Well, why do you assume everybody has a secret motive? I prefer to see the good in others, because what else is there to see? Everyone deserves kindness.

There's darkness in everyone. Even me.

Yes, but I know you. You can't lie to me while our hearts are one. You're not complete darkness, Roxas. I see the light inside you, even if you can't, and you don't need me to tell you this. Aren't most your attacks light based? And I know, you still will do what's right, because that's just who you are.

… No, that's who we are. We're one heart, remember?

Right!

As much as I like talking to you like this, we should probably stop this if we wish to maintain our form together.

Sora agreed silently and he could feel Roxas closer to him than ever before. All feelings of anger and traces of fighting slowly drained away, replaced by the warm satisfaction of being together.

One last thing.

Hm?

Their voices slowly melted into one, embracing each other in complete trust.

I love you.

AN: WELP. THAT WAS A THING. Trying to push no homo after that last line is kinda skeptical. I say I love you to my friends all the timmmeeee. Anyways, two fanfics I think are really awesome and you should read are Double Vision by LobaLu, which kinda inspired this mess and is definitely on my top 10 fave fanfics ever, and The Return of Erauqs by Theysharethesamesky, which is really nothing like this fic, but it's characters are great and is on my top 10 too. And for those people who've also read The Little Heart, it's next chapter is on *drumroll* anti-form. Maybe I should do a chapter of this fic on anti-form, idk. Anyways, stay awesome peeps and until next time, questions are encouraged and thank y'all. (How I talk is nothing like my stories lol)
