My theory is she IS the goddess. Or rather an avatar of the goddess since she can't set foot on the world directly. But that's not all. I also believe she is indeed a player from the MC's original world. Just not a regular one, but a GM. A GM in a game is basically a god after all. And considering how this manga takes a lot of details into account between the game and the other world, that seems the most likely to me. And lastly, I believe she was a fan of Lufasu in the game, but was unhappy with how Lufasu's story ended. And now she's basically writing a fan fiction in this other world, guiding everything to go according to how she wants the story to go.
It doesn't explain how this other world came to be, or how exactly Diina became the god of the world. But it seems to all fit. Of course there's every chance I'm wrong. I can only go on vague possible hints here and there. But that's what I think it happening.
I'm confused, who the heck is diina again???? Does she have another identity? ( ̄∇ ̄")
