Kingdom Hearts III: Prologue

Riku was sitting atop a tree in Destiny Islands. Sora then ran toward Riku and joined him. "Nothing's changed", said Riku. "Nope, nothing will" added Sora. Sora then faced toward Riku. "Hey Riku, what do you think it was, you know, the door to light?" asked Sora. Riku then pointed at Sora's heart. "This", said Riku. "This?" Sora asked. "Yeah", said Riku "It's always closer than you think."

"Sora! Riku!" Kairi yelled. She was running toward Sora and Riku. She had message in a bottle in her hand. "Kairi, what is it?" Sora asked. The message had King Mickey's insignia on it, "From the King?!" Sora asked. The three started to read the letter Mickey had sent. It read,

Sora, Riku, and Kairi.

Even though Organization XIII has been defeated, there is still more trouble. I have no time to explain in this letter. Meet me at Disney Castle. If you are wondering how you will get there I have sent a gummi ship to take you there, and I will explain everything when you get there.

Sincerely,

Mickey Mouse.
