Yes, he is still there. it is like he is in a dormant state.
But then what happened to the girl? Was she still alive when he "predated" her and is also in a dormant state inside him?
No, she is gone. He took on her form so he could remember her. I don't have a link but this is based on a light novel, if you google the name it should come up easily.
Oh, I see. Thank you for that. I'll look it up.

So what happened to the dragon in the first few chapters? He's still in Rimuru's stomach sack, right?
