From the things we have seen so far. She can’t communicate her animation requirements, and She doesn’t know why would she go back to Reality.

Natsuko isn’t a Director in the isekai world. She is an animator. She draws things when prompted by magical voice coming of a peg board(?).

She doesn’t direct the story of perishing into her desired plot line. She just happen to have a power to derail the original plot.

I think the biggest Δ will be bad director turns into good director.
