Kingdom cure: here it is! The official first chapter of this crossover!

Aki: Sure didn't take long, did it?

Kingdom cure: Well, originally, this was suppose to be a chapter for the Fairy Tail/Yu-Gi-Oh 5D's crossover, but due to the fact that readers want a Fairy Tail/Kingdom Hearts crossover, adjustments were made and you know the rest.

Chopper: And since the One Piece/Kingdom Hearts crossover is on hold, I'll be replacing Happy in being Kingdom Cure and Aki's assisstant.

Kingdom cure: that's right. And with that said, do you mind doing the disclaimer?

Chopper: Ok. Kingdom cure does not own Fairy Tail or Kingdom Hearts. Partial credit of this story goes to her beta reader.

How did this happen? They did nothing to them, yet their guild got messed up, a couple of their members got beaten up, one other member was targetted for no reason, and now, this.

Phantom Lord is a fellow legal guild from Oak Town. In the town of Magnolia is also a legal guild known as Fairy Tail. There has never been a conflict between them, until today.

For reason unknown, Phantom Lord suddenly attacked Fairy Tail's guild. Despite this, Fairy Tail's headmaster, Makarov Dreyar, took no action in response. Even when one of his 'children' tried to convince him to retaliate against this action, he told them to refrain from doing so. Instead, he told them to stay a different groups, in case if Phantom Lord decides to attack again.

Unfortunately, the morning after that incident, another incident came. One of Fairy Tail's team, Team Shadow Gear, has been ambushed by the same person who messed up the guild building. As if that wasn't enough, they were also chained to a tree and the leader, Levy McGarden, has been branded with Phantom Lord's guild mark. Furious, Makarov has finally decided to take action, in which the rest of Fairy Tail stongly agreed to.

However, even though they had the upper hand during their war against the opposing guild, minutes after the guild master went to find Phantom Lord's master, Jose Porla, he suddenly crashed back down to where the big battle was taking place. Not only that, he was also weakened. Taking this as a good sign for them, the rest of Phantom Lord's members regained their confidence and fought back. And since the master was in a critical condition, the only S-Class mage of Fairy Tail, Erza Scarlet, ordered a retreat, which the rest of the guild reluctantly agreed to.

Time after the incident, one of the recent members, Lucy Heartfilia, who was captured by Phantom Lord without her allies noticing and rescued by the only Dragon Slayer of the guild, Natsu Dragneel, revealed the opposing guild's plan. Turns out, the only reason why Phantom Lord did what they did was from a job that involves Lucy, saying that the client wants her back home. That is, however, what Lucy doesn't want to do for family reasons.

Shortly after the truth was revealed, noises can be heard from outside the guild's basement. Returning to the surface, the mages couldn't believe what they are seeing. In the water, behind the guild, was Phantom Lord's guild, making its way towards their guild. To make things worse, it's also preparing to fire Jupiter, a cannon that releases a compressed beam of energy that wreacks destruction wherever it passes. Erza quickly took action in response to this and changed into her extremely high defensive armor, the Adamantine Armor. Apparently, even with the great endurance it has, even though the guild was saved by its destruction, the armor was shattered in one blast.

Jose warned Fairy Tail that he will shoot another blast of Jupiter, but only if they refuse to hand over Lucy to him. They do that, he won't fire. Despite seeing the dangerous power, the guild refuse to give up their 'family member' away. Seeing how much they cared about her, Lucy was in tears. Despised by this action, Jose prepared another blast, giving them only fifteen minutes to live. However, while waiting for the fifteen minutes to go by, he also sent some soldiers called Shades, made from his own magic, to keep Fairy Tail occupied and keep them from getting any ideas. Despite the amount of ghostly soldiers, Natsu Dragneel, Happy, Gray Fullbuster and Elfman Strauss were able to pass them and get to Phantom's guild, the first pair much faster than the other by flight.

After trying to destroy the cannon from the outside, Happy suggested Natsu to destroy Jupiter's cannon from the inside instead. Natsu agreed and, with Happy's flying magic, despite being a cat, they went deep within the cannon to destroy the core and prevent Jupiter from firing. What they didn't expect to see was one of Phantom Lord's S-Class mage and member of Element Four, Totomaru, guarding the power source. It was a standstill for them both, with Totomaru's ability to control fire at his will and Natsu being resistant to all fire magic, being a Fire Dragon Slayer that he is. Eventually, due to a little miscalculation, Natsu was able to destroy Jupiter's power source. However...

"You're too late!" Totomaru shouted.

"What are you talking about?" Natsu asked.

"That wasn't the real power source; that was a decoy!"

"What?!"

"Then that means-!" Happy gasped.

"NOOOOOO!"

*MEANWHILE, OUTSIDE*

"Oh no!" Wakaba gasped, seeing a fully charged Jupiter cannon blast.

"Natsu's too late!" Macao shouted.

"I guess this is it then... It was nice working with you guys..." Cana said, trembling slightly.

Soon, the cannon was fired...

"IT'S TOO SOON FOR YOU GUYS TO JUST GIVE UP!" two voices shouted. Suddenly, two figures jumped over the wrecked building and headed towards the cannon, much to most of the Fairy Tail members shock, disbelief and worry, as they all screamed for them to move away from the blast.

"Ready?" asked one figure.

"Whenever you are," the other replied.

"Then let's go!" The first figure was thrown towards the building by his partner. "Command Style: Wingblade! Shotlock: Pulse Bomb!" Six swords of light hovers behind him, each charging energy blasts from the tip. The figure threw them all at the building's back legs, forcing it to lose balance and lean back. Unwillingly, Phantom Lord's Jupiter Cannon fired, completely missing its intended target.

"My turn now. Command Style: Thunderbolt! Shotlock: Lightning Ray!" The second figure suddenly had a glowing sword in his hand and rushed straight into the cannon at lightning speed, the moment the blast ended. Once inside the cannon, the figure reverted back to normal. "Now let's see if this thing likes some extra energy. Thunder Tracer!" Many waves of lightning bolt suddenly rained down inside the cannon. The second figure quickly made his leave, as the bolts were finding and destroying the power source. Seconds later, cracks formed and the cannon exploded.

"Now, you can't fire that thing properly," he coolly stated, landing in front of Fairy Tail.

"He got that right," the first figure agreed, landing next to his partner. "So then guys, what's going on here?" He has brown spiky hair, blue eyes and tan skin tone. His hoodie is grey with black lining and red hood. His sleeves are black with white lines separating them from the red edging. His shirt is black and has a picture of a white Fairy Tail emblem. He also has on black fingerless gloves, red pants with a dark blue belt and yellow shoes with white stripes. Around his neck is a crown pendant.

"Seriously everyone. We left for a few years to get some jobs done and we come back to see you guys in a war with another guild. Just what did you do?" the other teenager asked. He has on a white vest with yellow linings on the side and a high black collar. Underneath the vest is a bright yellow sleeveless shirt. He also has on a pair of black wristbands and baggy pants with a black belt, as well as white boots with yellow lining on the bottom. On the back of his vest and his left shoulder is a black Fairy Tail emblem.

When everyone got a better look at the duo, they all began chatting amongst themselves about them. At least, those who saw them for the first time.

"Who are those two?"

"They look familiar."

"I know them! Those two are-!"

"Sora! Riku!" Cana called, running up to them. "What great timing! We could really use some help!"

More chatter came as the card mage explained everything to their saviors.

"No way! The Sora and Riku!"

"They do look like the two mages from the articles about them."

"That's because they are them!"

"We might have a better chance to win!"

"That's the story," Cana ended.

"Guess that explains why our guild is a mess," Sora said.

"Now that we explained our side of the story, explain to us why you didn't answer the lacrima earlier," Bisca demanded.

"Why don't you ask this genius?" Riku asked back, referring Sora as the 'genius'.

"Ah ha ha ha... There's a good reason for that," the brunette tried to explain. "I may have accidentally broke it...?"

"Broke it how?!" Alzack asked in disbelief.

"Let's just say that he accidentally used it as firewood one time," Riku explained, resisting the urge to face-palm at the memory.

"IDIOT!" some of the other mages shouted, hitting the guilty boy in the head.

"Last time I remember, now is not the time to think about my mistake!" When Sora shouted that, everyone remembered about the returning Shades.

"Sora is right. We still have a war to win!" Cana shouted. Everyone else cheered in agreement. All of a sudden, the Shades were all returning to Phantom's guild, as the building began to change shape.

"What are they up to now?!" Laki wondered.

"What is that? It must be a joke..." Cana said.

"It's a giant. A magical giant!" Loke identified.

"Bow down and beg for mercy, you brats," came Jose's voice. "Bow down to me, or feel despair until your final moments." Seconds after he said that, the reaper-like ghosts returned to battle.

"The Shades are coming back!" Alzack stated the obvious.

"A giant and ghosts. What are they planning on doing?!" Bisca wondered.

"You guys just focus your attention on the Shades!" Riku ordered.

"Riku and I are going into that thing!" Sora said.

"Why? I mean Natsu will find a way to stop a giant, won't he?" Cana asked.

"What do you think that is to you now, besides a magical giant?" Sora asked.

"A magical vehicle," Macao answered. Almost everyone paled in realization to that.

"B-But just look at that giant! It's not like it's going to attack us, right?!" Wakaba asked, panicking.

"Not physically. Look." Riku pointed at the giant, as it was beginning to draw a magic circle. "That's the magic circle for one of the fobidden magics, Abyss Break."

"If that thing completes that circle, we'll be in a huge trouble!" Sora explains. "All of Magnolia will be destroyed! Which is why Riku and I are going! We'll help Natsu, Gray and Elfman find the power source!"

"They say two heads are better than one. In that case, five people finding the power source is better than three. And with some reinforcements we have here, it gets even better."

"... I got it. Leave things here to us. You two, hurry up and go!" Cana commanded. The two boys high jumped and glided over to the magical giant. Some of the Shades noticed and went after them.

"Sora! Riku! Look out!" Wakaba warned.

Whether they didn't heed his warning or ignored him, the two kept gliding foward, not minding the pursuing Shades.

"Are they crazy?!" Macao asked in a worried tone.

"Just leave them be," Alzack said.

"Al's right. After all, this is Sora and Riku we're talking about. They'll figure out something," Bisca supported.

"Bisca's right. Now that Master and Erza are both out, those two are our only hope for winning this war. If anyone can stop this war, if not the Master or Erza, it's them," Cana agreed. "Now then, let's finish this!"

"YEAH!"
