Riku? Well, there are people in some part of the world who just don't know who Riku is! Well for starters, he's in a game called Kingdom Hearts. You start off in the game as Sora, who is Riku's friend. You get to talk to Riku a bit and find out about his personality and how cool he is on the island and do some other stuff. Then suddenly you're 'transported' out of your home and you seek to find this "Riku" and this "Kairi"! Riku is one of those characters that make this story flow. He's pretty much fit to be the main character but whatever. He is one of the main characters though and he's almost like a porthole to the villain. And well, there's Riku for ya.
