There are a lot of adorable characters in Kingdom Hearts, but I do have a particular soft spot for Riku. In the first game he hurts a lot of people he cares about, and ever since then he's been struggling to make up for it. It's a good thing he has Sora as a best friend; he can't forgive himself, but Sora forgives him enough for both of them.

When Axel's assigned to Castle Oblivion, he says to Roxas, 'Since you're my buddy, I guess I can fill you in. I'm gonna be at Castle Oblivion for a while.' There's something really endearing about the fact that Roxas records not only the 'Castle Oblivion' part but the 'since you're my buddy' part: Axel is going to some place called Castle Oblivion. He told me because we're friends.
