I wanted to make this a fight scene between Sora and Riku about Kairi but I decided to stick with this. If you want to know what happened to the guys, they were fighting :P
Disclaimer: I'm sure you know :)
Maybe fighting the darkness is fighting yourself? So...what if you can't win?
"Kairi! Kairi!" a soothing, familiar voice called out to her. "Kairi! Open your eyes!" Kairi did as she was told. She found herself...on a beach.
"Kairi!" the voice called out again.
"Aqua? What's going on? Where are we?" Kairi asked. Aqua revealed herself in front of the red head.
"You're trapped in the dark margin," the blue haired woman told her. "And so am I." Kairi gasped as she realized what that meant. "But," Aqua continued, "You have a strong light in your heart that is only with certain people. Which means you can escape."
"What about you?" the younger girl asked.
"I can't escape myself. You can save me. But not now. Not yet." Aqua smiled as Kairi was engulfed with light.
"Wait!" Kairi called out as she extended her hand towards her.
"Continue to fight the darkness," Aqua explained, "But remember that everyone has it. Including yourself."
