That stand animation is coming out beautiful.
Here are ideas I had sketched for Anita.

I want to add that I disagree that she'd not know how to fight. She may not be a martial arts master but IMO she has trained with people for this day that she will set off on her quest to find Dee. I expect that she has traveled all around the world growing up. Enjoying life. Improving the lives of all those she encounters. She's on the road to becoming humanity's savior. So I imagine a story similar to those that are destined to become such a thing. The young adventurer trope. Going from school to school. Making friends wherever she goes. Saving the day and enriching lives.
