Here's the rest of the chappy. Enjoy guys!
Sora gasped for breath. Nothing he or Riku were trying was working. There was one attack left to use, but he and Riku had to save that for a last resort because of the collatoral damage it would cause. 'Darn you realistic...ism?' He charged in again, blown away for the fourth time and surrounded by a ring of heartless and dusk. Sora ignored them, focused on Ansem. He chucked his keyblade at him, grinning. It cut Ansem's arm, which began to slowly bleed. He caught his keyblade, now starting to get angry.
"SORA! WATCH OUT!" Kairi screamed, obviously scared.
He ran away, dodging little blasts from the floor. Spinning around, he fired a blast that blew away 50 heartless in one swing. He grinned. 'Cake.' He turned away again to face Ansem.
"I think it's time you explained some things Ansem. Why are you here? What the hell is going on?"
Ansem grinned. "I'm here for the keyhole. The one you never sealed. Destiny Islands will soon be mine!"
A dark spasm opened in the ground and Ansem descended into it. Sora dove into the spasm head first, cutting down flying heartless in front of him. He looked up to see Riku falling right behind him. He touched feet to the floor, looking to Ansem, now transformed into a massive heartless. Sora laughed.
"No collateral damage here! Let's go Riku!" Sora yelled, running towards him.
They ran into each other, except when they collided, a flash blinded Ansem. When he opened his eyes, he saw a teenager with spiked up silver hair, black clothes and yellow eyes.
"You fused?! What the-?" Ansem yelled.
Soku (Hehe...mixed names...) ran in and cut him off with his Oathkeeper and Riku's keyblade. He rained a flurry of blows on Ansem and flung him into the air. Soku jumped up, slicing Ansem with both keys. He jumped to the floor, backflipping and holding Oathkeeper in the air and pointing it at Ansem. A massive beam shot from the blade, shining on Ansem. Ansem, however did not notice Sora and Riku had seperated at Riku was flying inside of the beam. Riku cut Ansem several times, and Ansem dropped to the floor, dead.
Sora and Riku high-fived. A door stood closed at the end of the spasm. Sora and Riku both held Oathkeeper's handle, and a beam shot from the end, sealing Destiny Islands.
They flew back to the surface of the island, and reunited with the ones they loved. Riku and Selphie started kissing, and Kairi and Sora did as well. They smiled, and joined in a group hug. Their island was finally safe from danger.
