Can Yuan have a spirit too? Just like Kratos, he knows a lot about summoning because he was there when Mithos made all those pacts. But damn it all of it's Gnome or Sylph. I'd say Origin for the irony of it all, but as canonically proven Origin is a horrible pessimist who can only be tamed by optimism. That's never gonna happen in Yuan's case. So how about Celsius? Can I have dibs on her?

Also, if Sheena needs Volt translations and Raine is still out cold, Yuan's her go-to guy.
