Does Ralsei know that Kris isn't the first hero?

Really makes you wonder what the prophecy entails if Ralsei genuinely thinks being nice could make a difference

Toby has so much stuff that he has to wrap up in 3 chapters
So unless 5-7 are longer than usual or there's a secret chapter, I don't see how he'll do it without cutting corners

I'm actually starting to believe the theory that the character we make at the beginning is our actual body and our soul somehow ended up in Kris
In chapter 4 we see that Kris is completely fine and can move normally without the soul
