Answer 2

(Spoiler)
Okay the bad guys in the game were Organization 13. The leader of the Organization is the last master. He is hard! Anyways, in the ending, Sora and Riku make it back to Destiny Islands (the island they lived in) Kairi is there waiting for them with Donald, Goofy and King Mickey. They meet up and then after the credits, they find a bottle with a letter in it that the King wrote because it has his seal. You never get to see what was in the letter. This proves that there is going to be a Kingdom Hearts 3. The maker of Kingdom Hearts has not yet started Kingdom Hearts 3. My guess is that the game will come out in 2008.

Edit: By the way, Organization 13 is this group of 13 black hooded people who wanted to take over the worlds with Kingdom Hearts. They wanted the Heartless hearts to help them. The more Sora fought Heartless, the more Kingdom Hearts grew. Hope this helps clear the story a bit. If you have anymore questions, e-mail me at [e-mail]
