"Saix?" The name didn't ring any bells, and Sora wasn't sure what to do. It had to be someone bad, though, for Xion to be this shaken. "Who's that?"

It was in the brief pause after he said that when he finally noticed someone familiar nearby. It was the guy with the blue hair that Sora remembered meeting over the network, who said he used to be in the Organization but wasn't anymore. Sora still wasn't really sure what to think about him, but...could he be the one Xion was talking about?

No, Sora remembered. His name was Isa, wasn't it? At least, that's what he had said. So what was going on?
