Sora drifted downwards, it had been five years since had experienced this sensation for the first time. The feeling of sinking through water but breathing it like air. He righted his body so the he feet we're under him. He opened his eyes and a moment later he felt his feet connect with the darkened floor. As he landed the floor lit up and pigeons began to fly from the darkness that had covered the floor. He looked at the design on the floor. Five years ago it had been snow white on the platform, now however it was different. It was blue With a picture of Sora standing in water, but the water was a smoky black and in the reflection of it was a dark figure with yellow eyes.
Soras stomach knotted up as he realized what it was he was standing on. It was his anti form. He took a step forward and walked until he was off the demented picture of the dark side of himself and comfortably on the edge of the side with his normal self. He turned around to look at the full platform. The azure glow of the floor startled him a bit, it seemed so eerie.
"Its always waiting for you. For you to show weakness"
"Who's there?" Asked Sora, looking around. But he knew the answer. It was the voice he'd heard back then too.
"If you're not careful... you... might... just... slip..."
"What do you mean?" Sora asked demandingly.
"... You already know. After all, who knows better than you?"
Sora's eyes widened in shock. And he looked back across the platform. From the side of the platform painted with water a dark figure rose from a smoke that seemed to seep from the floor. As its head breached the surface its yellow eye's glowed, emotionless and hungry. It looked towards the sky and rose the rest of the way from the ground before it fell on all fours to the ground.
It was so silent and its aura was so dark. It was the nightmare of many but known by none. Sora had been so careful to hide this side of himself from his friends, and he never fully understood why he did this himself. But now, faced with it he understood. Its whole purpose was to fight, to kill, to take the hearts of those filled with light.
Sora reached out his hand and summoned his key blade. His hand radiated light and it appeared in a brilliant flash in his hand, the kingdom key.
"Be careful, and remember, darkness cannot exist without light, just as light cannot exist without darkness."
Sora didn't care for deciphering this meaning, he had a enemy that fed on the fear of the weak and cornered, and right now, Sora felt like he fit the description. He readied himself as the dark form readied to pounce. For a moment they just stood there, silence was their battle, the definition of the need to live.
The anti-Sora launched itself, pouncing from left to right, not making a sound, every time it connected with the floor a puff of manifested shadow arose from the floor. It swiped at Sora and he parried, swinging his sword up vertically. He spun and brought the key blade down on the antiform, he felt it connect with the beasts head but it spin with the hit and kicked Sora in the ribs. "Gaaahh!" Sora groaned with pain as he stumbled back. He covered his chest with his left hand, leaving his right hand to take to force of the anti form next barrage solely on its own.
Sora gritted his teeth and deflected a hit then took another swing at his darkness but it back flipped into the air and landed a few feet away. Sora charged at it and swung his key blade in a wide arc catching the darkness in the shoulder, sending it sprawling across the floor. Sora spun his key blade in his hand, and jumped into the air.
"I will not lose to you!" Sora yelled and smashed the key blade down into his enemy. It slammed against the ground, cracking the platform. It lay on its back and began to dissipate into a black smoke. As it did it looked at Sora, its cold eyes still showing no emotion. Then as if disappointed it closed its eyes and evaporated fully leaving Sora alone on the platform. He looked down at were the cracks in the floor spread from. They were directly in the chest of the normal Sora that was painted on the floor.
