This story was REALLY good. I couldn't stop reading and when my computer froze half way through I nearly cried. I was actually hoping there was more to it. It would be really interesting to see how you used the Kingdom Hearts tale in your story..

The 'sequel' is called 'The Legend of the Card Crystals' and is on Fanfiction.net. It's by fatalfeline. I wrote chapter 7 and the epilogue, if it's not blatantly obvious when you read it.
