Xion carried Lea all along the side of the castle until they made it to the place he told her to stop. When they landed, Lea brushed himself off and thanked Xion for bringing him, who only smiled in response. "Do I even need to ask you who you are going to fight, or should I know already?" She asked.

Lea sighed, "You should know, I wanted to fight him in the Keyblade War but Sora beat me to it. But now, I am going to finish this."

"Do you need help? Isa is no pushover, he never was, I'll help you if you just as for it." Xion responded, placing her hands on her hips.

Lea shook his head. "I have to do this alone Xion, you know that," Lea replied.

"Okay, just—be careful, alright?" Xion then hugged Lea, which caught him off guard for a second, but he gladly hugged her back. Once they departed, Xion flew off into the sky once more, leaving Lea alone.

The red haired pyro took in a deep breath before he began to walk down the hall into a very familiar room: Proof of Existence. He then walked up to the panel that belonged to Isa that was standing tall and glowing, showing that he was still alive. Lea only took in another deep breath before he walked through.

When he walked through, Lea found himself in a large rectangular shaped room with huge windows covering one wall that showed the place where Kingdom Hearts used to be. This was the room that Sora, Donald and Goofy fought Saix in before on their second journey, which is exactly how Lea knew the blue haired man's lingering will would be here.

And, just as he suspected, when Lea rounded the corner, he saw the lingering will of his former best friend standing by the windows, looking out at the pitch black sky before them.

Isa's lingering will immediately noticed Lea's presence and turned around. "I am surprised you made it here in one piece, Lea," he said coldly.

"Come on Isa, you're really surprised? I was the kid that made us do all those crazy things when we were younger, remember?" The pyro asked with his hands on his hips, "I always come out in one piece."

"Hmph," Isa growled, looking out at the sky through the windows again, "Chaos is coming; nothing will change that, not even you."

Lea rolled his eyes. "In all honesty I knew I wasn't going to change that; me against the god of discord? Yeah, that wouldn't turn out pretty."

Isa didn't turn around when Lea continued speaking. "Which is exactly why I am not even going to try facing him," Lea summoned his keyblade as he continued to speak, "So I decided to defeat you instead."

This time, Isa turned around. "So even after all these years you still don't know when to give up, do you?" He asked, "Tell me Lea, do you really think you are going to be able to defeat you're your best friend?"

Lea lowered his head for a moment. "We aren't best friends anymore, so don't even try to con me into that one," he spat. "But even so, I don't want to defeat you, but I know I don't have a choice."

Lea pointed his keyblade at Isa as the lingering will summoned his own keyblade that he used during the Keyblade War. Lea knew that if Isa really did have a face right now, he would be smirking. "Well than let's settle this once and for all, shall we?"

(The Thirteenth Struggle – Kingdom Hearts II) "I'll be glad to!" Lea exclaimed before he ran full speed at Isa, pointing his keyblade straight at his former friend. As soon as the two met, their keyblades clashed several times, both sides trying to get a hit on one another but they managed to block the blows. However, Isa managed to push Lea's keyblade back hard once, which also sent Lea sliding backwards on the ground. The pyro shot back up just in time to see Isa jumping in the air towards him, his keyblade pointed down as if he was ready to impale Lea in the chest. But Lea managed to jump in the air himself and hit Isa, sending the lingering will back flying into the air towards the wall. However, when Isa made it to the wall, the lingering will managed to use the wall to his own advantage, using it to help him do a recovery and land back on the ground safely.

"You're going to have to do more than that to stop me!" Isa said as he began to glow a blue light and levitate in the air. Lea knew what was coming and quickly prepared his fire attacks and his keyblade before Isa came crashing down on the ground, his keyblade sticking in the floor. Isa instantly pulled it out of the ground and ran towards Lea, swinging his keyblade quickly to try and slash the pyro. Lea growled for a moment, hating his former best friend's berserker form with a flaming passion. But Lea didn't have much time to think about that since Isa continued to slash him, and then, after several slashes, successfully hit the pyro right in the side, sending him flying into the glass windows that cracked on contact.

Lea only said a silent prayer, thanking Cosmos that the glass did not break or he would be a goner, but he did hit his back hard and fell to the far away ground quickly. Taking in a deep breath, Lea got back up, looking right at Isa, who had just got out of his berserker form, and was glaring right at him. Isa then ran at Lea again, his keyblade ready, but this time, Lea brought his keyblade up to block the attack, the two keyblades meeting instantly. Lea only glared at Isa's will, using all of the force he had to try and push Isa off of his keyblade but it was proving more difficult then it seemed. Instead of trying to push Isa's keyblade off of his, Lea took one hand off of his keyblade and blasted a fire attack at Isa, sending the will flying back.

As soon as Isa was off of him, Lea put his hands on his hips and began to take in deep breaths. He didn't know how he was this winded already, but he figured that the lingering wills were stronger than their counterparts, so just decided to leave it at that. When Lea looked back over at Isa, the will had already recovered from the attack and was beginning to glow blue light again. Lea knew he couldn't back down this time though and ran towards Isa, not afraid anymore. Isa jumped into the air again as Lea ran towards him, pointing his keyblade towards the ground as he readied to impale Lea with it. Thankfully, the pyro avoided the attack, but this caused the keyblade to stick into the already cracking ground, and the moment that happened Lea knew it wasn't going to end well.

And in the blink of an eye, the ground beneath Lea and Isa cracked; breaking and falling due to Isa's berserker impact. The floor began to fall in huge chunks down; heading for wherever the lowest ground was that could hold the weight of it. Lea thought fast and quickly summoned his keyblade rider for this cause, trying to fly out of here, but Isa grabbed onto the pyro's ankle and stopped him from doing so. Lea quickly resummoned his keyblade, trying to hit the lingering will off of his ankle, but the pyro knew it was no use and the two were sent crashing into the ground just like the floor that once stood beneath them. (End the Thirteenth Struggle)

Lea was not sure how many floors the two fell down to, but whatever floor they were on now, the impact hurt like living hell. Lea groaned as he began to get up on his hands and knees, feeling for his helmet but the crash must have caused it to come off because it was no longer there. Instead, Lea felt a gash by his hairline, the blood already dripping down towards his nose, but besides that he had no other visible injuries. Lea then looked down at his ankle, seeing that Isa's will was no longer holding onto it…

Wait a minute, where was Isa anyway?

Lea quickly summoned his keyblade back to him and keep it at his side as he looked around for the lingering will, which was no were to be found. This was when Lea noticed how much rubble and large chunks of the floor had came down on these several, however many floors. What made the situation even stranger was that it was completely quiet in the room, not a sound to be heard besides Lea's own breathing.

It took a few more moments for Lea to finally hear the sound of coughing and groaning behind him. Lea turned around quickly, seeing a huge pile of rubble and several large chunks of the floor that were just barely moving. Cursing to himself quietly, Lea ran over to the rubble, unsummoning his keyblade before observing the pile. Then, as quick as he could, Lea placed his hands on the largest piece of the floor in the pile with all the strength he had left within him. When Lea finally moved the large chunk, he looked to where it once was and saw Isa's will, coughing and barely moving in his place. Lea looked over right next to the will and saw his keyblade, which he quickly picked up so Isa couldn't pull any fast moves, but the pyro knew it was over.

Isa coughed before finally speaking. "Just end me—" He coughed again, taking in what sounded like deep breaths. Lea knew that he must have got hit right by the giant chunk, dealing the final blow to him. "Old friend."

Lea looked down at Isa, light tears forming in his eyes. This was his best friend, the one that snuck into the castle at Radiant Garden even though he didn't want to, the one that bossed him around when they joined the Organization, the one that fought him when he and the other keybladers were trying to save Ven in Castle Oblivion. And now, here he was, lying hopelessly on the ground, asking Lea to end him, to put him out of his misery.

And so Lea pulled Isa's keyblade back and stuck it right in the lingering will's chest, ending his former friend's will for good.


If this fight scene seemed pretty short, which it was, please don't be mad at me since you were expecting something bigger. I meant to keep the fight at this length since I really wanted to show how it was Isa's own actions that eventually lead to his downfall, making him hopefully realize that if he acted differently, it could have ended differently. It's kind of like symbolism, but yeah, hope you get the picture.

So I have another chapter done, even though I was going to put it in after two more chapter which have yet to be completed. But if you guys review I might release it next, since it doesn't really matter what order it goes in, I was just planning to put it in later. If you guys do want me to update again, you guys better review cause the next chapter is something I think everyone has been looking forward to for a long time X)

So please R&R if you want to see another chapter today and look out for the next chapter!
