He was running as fast as he could but, as if in a dream, time seemed to slow down and the distance seemed to grow until the scene before him stretched to the edges of the earth. His key blade flashed as he cut down the opponents in his way causing shrieks and gushes of air as heartless dropped and faded from existence. He screamed, trying to draw the attention of the characters in the 'dream' before him. Another scream followed his own and then another, another, and another until the air was full of voices drowning out the shrieks of the monsters. The screams never made it to the ears of the one they were meant for. He screamed once more, swinging his key blade once more. Finally blue eyes turned to meet aqua eyes, and for a second he thought it would all work out. That everything would be alright…
Blue eyes widened in surprise and then in pain. Lips opened in a scream of agony and aqua eyes could only watch as a razor sharp black tail burst from the chest of the blue eyed boy, having pierced the whole way through. A spray of crimson hit the ground with a sound like a hundred raindrops. Aqua eyes watched as the blue eyed boy was lifted from the ground. They watched as the golden handle of the original key blade slid from nerveless fingers to shatter on the ground as it's master was rendered unable to wield the weapon.
Aqua eyes closed in deep agony and a single word tore from a throat already sore from screaming, "SORA!!"
The blue eyed boy stared at the sky for a long time, suspended by the coal black tail of the heartless monster. All fighting had ceased and when it finally seemed as if the silence would never end, blue eyes settled closed and a beautiful shining light lifted from the sundered chest.
Once again, he was running as fast as he could. He knew it must be too late to save the boy, but the heart was still there, and that was something he could save. Again time seemed to slow, but this time he was truly covering the distance. His lips started to curve in a slight smile of grim victory when, as if out of nowhere, unforgiving jaws closed over the light of his best friend. A sound, not unlike the tinkling shatter of glass, met his ears. The black beast disappeared into a flurry of black smoke, having accomplished its main objective. The remaining heartless followed.
The owner of the aqua eyes dropped to his knees before the body of his once forsaken friend. Footsteps approached slowly, as if unbelieving. A voice, small with horror and grief spoke broke through his melancholy, "… Riku? Is he really…?"
Riku looked up towards the owner of the voice, noticing the disarray of her red-brown hair and pink jumper. His eyes finally met hers and he felt his starting to grow wet. She sobbed and turned to the closest body for comfort, not realising that her comforter was just as devastated as she was. Riku just stared at the ground now.
A cry wrenched from the throat of one of the other bystanders and Riku whirled around, just in time to see the body fade from existence. Horrified aqua eyes turned to face the eyes of the bystander who had yelled. Small black eyes (1) met his and he knew then. He knew…
Sora had become a heartless.
