I don't know why. I just thought up this idea after re-watching some Kingdom hearts video and catching up to Soul eater. I wondered to myself about if there was a soul eater and KH crossover. I checked it and some were good and all. But I decided to try to make one of my own. So have here it is. As for Timeline this is KH2. Just to make it easier and give some ideas. Also decided to make it anime but when there's a boss battle, want to give it that feel of as if playing Kingdom hearts 2 with the objective screen on top. So the format might be weird but imagined it as if it was a game.

Cut-scene

Eyes fluttered open slowly. It was pitch black trying to look around. Nothing was visible. A grumbling noise was heard throughout the area. As if someone just woke up after being beaten or fighting and lost. Soon light came in and then actual vision of the surroundings appeared. The boy looked young in his early teens and had amber colored hair with a pair of sapphire eyes. His name was Sora. He looked around with his hand on his head quite in pain and trying to rethink what happened. Where is he? That was the first thing that came to mind. He saw benches, wooden ones and looked to see himself in a church. He shook his head trying to help think.

"W-what happened? Why is it a blur? What was the last thing I was doing?" He asked himself these questions. But all he was receiving were white blanks before standing up. He shook the last bit of fatigue and was now fully aware of his surroundings. Although he still couldn't answer the previous questions. It was getting to him. Why is he in this place? Had he collapsed here? More importantly, WHAT is this place? Regardless he had to think quick. He then remembered one thing.

"Donald, Goofy? Where are they?" He asked looking around but no answer came. Mentally and physically. He realized he was alone. No allies and in a place he never ventured before. He sighed. He was going to be on his own for the moment. And it seemed he would have to be on his toes. He turned around now seeing a group surrounding a lavender hair androgynous teen. Wearing a black robe and a white collar to the top and clutching the free arm as if nervous. They looked like they were going to cause harm.

'I have to help.' Sora quickly summoned his keyblade, the Kingdom Key into his hand and got in his stance quickly. Although he stopped as he covered his ears hearing a high pitch scream. When it finally stopped he looked at the teen that was in trouble. Everyone was gone and all that remained were whitish-blue orbs. A sword was being held, pitch black and few white stripes near the hilt of the weapon. Sora was just mortified. It was one thing to fight back and try to knock them out, it's another to kill them right there. And to add they weren't even heartless, just people. The person walked up to the orbs eating them all. The teen looked at Sora and the weapon in his hand

"Hey, that weapon looks like a key. I wonder if it can open any door or lock it wants. Wonder what it feels like in my hand." The tone sounded a little excited with a little hint of madness at the end as the blade was then turned into a puppet like thing sticking out of the teen's back as if they were a pair and inseparable. The puppet like monster was black and had his face and eyes with a white X.

" What are you blabbing on about now Crona? You got to stop yapping and start doing work. We need more souls!" The parasite yelled as it started puling on his cheeks quite painfully.

"R-ragnarok, s-stop it. It hurts and I don't like pain." Crona had said, the voice seemingly hard to actually understood thanks to the actions of Ragnarok

"You listen to me. You don't order me around, second-", he stopped talking seeing Sora and more importantly his soul. He grinned mischievously. "His soul looks tasty, this should be a easy one to get." He snickered at Sora who's face at the moment was just in shock.

"Your a heartless." He readied himself to fight. He never saw anything like what this person had. But it resembled a heartless and that was good enough for him to fight. And the scene before didn't help change his decision. A sudden voice spoke to Crona.

'Kill the boy, take the weapon. Got it?' Ragnarok laughed at Sora thinking that he can actually win, let alone hurt them.

"I forgot I can kill. it shouldn't be any problem. These doors open inward don' they?" Each sentence had a shift of glance. Ragnarok opened his mouth to talk once more.

"You are a clown thinking a crappy weapon like that can actually hurt us. You got another thing coming loser." Sora frowned at Ragnarok as it laughed once more at him before turning back into the blade and into the hands of the user. Sora charged sending a strike but it was as if nothing happen, no flinching at all. Crona hit Sora with the hilt of the weapon sending him back. He recovered but realized that he wouldn't be able to do anything. It was his hardest strike and yet nothing.

"Darn, what now? My attacks, they don't work?" he asked himself seeing that his strike won't do anything and Crona was more than willing to kill Sora. In the air above the church was a woman wearing a hood concealing her face and riding on a broom to stay in mid air. This person was obviously enjoying the spectacle down below.

"Crona against the boy who wields such a legendary weapon. This seems to make a very interesting turn of events."

'In a different location'

A red haired man was in the infirmary and looked around. He talked to himself moving passionately about his daughter. He looked like a idiot when passing by him though. He heard a voice tihnking it was his nurse and smiled. He closed his eyes and hugged the newcomer. That someone was in a lab coat. He opened his eyes to see his worst nightmare. His eyes went white and his face turned pale. The person that he had hugged was the one he was avoiding and that had experimented on him.

"Good to see you still alive Death. Or do you prefer Spirit?" He said smoking a cigarette in his mouth and twisting the screw that was sticking out the side of his head. Spirit was on the bed beyond shock, hitting the bed sobbing. He was scared at the sudden meeting of him.

"Whyyyyy Stein! Out of all people, you had to show up?"

"Is it a problem? I just wanted to see a test subject."

"Nice try, but I'm not afraid of you anymore. I'm over it." Stein blinked as he looked at Spirit being under the covers and trembling noticeably.

"Over it huh?" Stein asked before sighing and looking at Spirit seriously his stare alone showed it. Spirit also got serious seeing that he was going to say something.

"What is it Stein? Something bad is happening?"

"The demon sword... has appeared. And it seems, we have a guest."

OBJECTIVE: Survive for two minutes against the mysterious swordsman!

Sora was standing still ready to guard anything coming it's way. Although he would need to depend on reaction time more than anything else. The new fighter had sent a dark purple shockwave ripping the ground it was riding on and coming in fast. Sora had to dodge roll out of it's path not wanting to know if the keyblade can deflect it as he needed to look back at Crona wanting to know where the two were. He turned his head quickly to see Crona was already close and started a vertical slice. Sora quickly blocked it as a reaction more than anything. He couldn't believe in that short frame of time Crona had already been in front of him without a sound. Sora then started moving parrying a horizontal slice as he ducked and tried to attack quickly but missed. Crona nearly got a opening until Sora jumped back just missing the blow.

'Not only can't I get a hit in, person is also quick with attacking and evading my moves.' he thought at the fact he missed and the possibility that if he even connected would it have hurt or even cause a slight flinch? The timing was perfect and yet, he didn't connect. Sora was confused mentally. He was used to attacking and parrying blows to make his own attacks. But now he had to be the defensive side and make sure not to get hit. He did not want to be near wanting to be sure that he wouldn't get hurt and still be productive. But it changed quickly when he was on knee hearing Ragnarok screaming in his blade form.

"Nngh." he growled out in pain. It was affecting him greatly as if stunning him. It was followed up by Crona in mid air sending a strike from above. Sora guarded luckily before Crona stopped the attack as soon as it started, ducking and thrusting forward catching Sora off guard. Only reasonable action for him was to turn to the side. In response, it was followed with a side attack involving the arm. The attack worked as even though Sora put his arm for block, he flew back away stumbling in pain and trying to think about the situation he was in. It wasn't even like a normal punch, it hurt more than usual.

"Not good." Sora said panting at the attack and the amount of strength to keep fighting was fading. "I got to keep going."

Cut-scene

Sora was rushed by Crona once more being attacked by the hilt hard being sent flying across the inside of the church and hit the wall with a loud thud. He knew he lost. He couldn't keep fighting. Crona slowly walked up to him Ragnarok readied in hand. The battle was over and the two knew. The androgynous teen was in front of the boy on the ground helpless. Slowly raising the weapon in the air.

'I-is this how it's going to end? Just like that?' he asked himself looking down at the floor. The boy closed his eyes seeing as though he was going to be ended until feeling as though nothing happened. He looked up to see a girl with her hair ash blond color. Wielding a scythe in her hands in a red and black design on blocking the reassuring blow that would have end it.

"Hey, what was that Crona. How could you waste precious time like that and don't finish" Ragnarok said yelling at the inability to finish the job.

"Sorry, I wasn't expecting a girl to come and help him. I'm not good with girls either."

"Well it doesn't matter. Kill all of them and eat their souls got it?" he said reassuringly and turned back into the black sword. The girl looked back at the kid seeing his state and thought he might not be able to help.

"Don't worry about it. We'll take it from here." the girl had said to the boy lying on the floor. Sora placed his hand on the ground and stood up shakily. He walked next to her panting a bit. He was still shaken up but still had the will to keep going.

"Hey, I can still fight. Don't count me out just yet." The girl turned to the right looked at him and nodded being serious before having her attention to the one that was needed at the moment.

"Alright then, let's go." she said with confidence. Sora was really hoping that she was a complete ally and not turn when they win. He also hope that with this new person aiding him now, the two can take Crona on and win without a problem.

Well that's chapter one. I decided this is probably the best way to start after thinking it over and over. I really wanted the length to keep going though so it was like a little kick in the shins to me. But enough of that. Here's the start. Let's see where it goes from here. Till next time.
