Prologue: Quest to Destroy Kingdom Hearts
"Roxas..." said the girl with shoulder length jet black hair as she was closing in on her last breath as she lay in our hero's arms. "All those hearts that I've captured...Kingdom Hearts...set them free."
"Kingdom Hearts...free them" he repeated. Roxas watched in horror as the girl began to crystallise from her feet towards the rest of her body.
"It's too late...for me to undo my mistakes. But you can't let Xemnas have Kingdom Hearts. You can't...good bye Roxas...see you again. I'm glad I got to meet you...and of course Axel too. You're both my best friends." She slowly placed her hand on Roxas' cheek with all her remaining strength. "Never forget. That's the truth." And with that her hand slowly fell back down.
"No." Roxas said as he caught her hand and held it tight in an attempt to keep the girl alive. "Xion...who else will I have ice-cream with?" His desperate efforts to keep Xion alive fell on deaf ears as her crystallisation continued up her body and crumbled into millions of pieces that flew into the sky, showcasing a beautiful sight of twinkling lights and leaving nothing but a single sea shell in her place. "Xion..." was all that escaped Roxas' lips as he helplessly wept for the loss of one of his only friends.
Once he had collected all his thoughts together, the young Nobody decided to fulfil his friend's final request. He was going to destroy Kingdom Hearts. And nothing would stand in his way.
