It does suck to hear about sora not being the true keyblade metasr. but it’s still not over yet. And Riku being the true keyblade metasr, still doesn’t mean much, at least not to me. Not when there’s still a role to play for a lot of them including Sora. He may not be chosen, but he’s been fighting as hard as ever to save his friends, and now save the people whose hurting. Right now, the issue of the keyblade chosen one thing is no longer a concern anymore.
