you've played kingdom hearts 2 and finished it? ohkay good. remember when sora, riku, and Xemnas fought within kingdom hearts? Kokoro (which means heart in Japanese) was created during the moment Xemnas was defeated. There was so much energy that a mix of emotions and spirit from each of the opponents escaped from their body to create this woman. With the memories of Sora, the determination of Riku, and the wonder of Terra, Kokoro has found her way out of her birthplace of Kingdom Hearts and into an abandoned Castle That Never Was.
Thats my entry. xD when I found out you loved KH, I just had to enter.
