In contrast to the other two, Asuka's story is much more nuanced and exists mainly in the background. Through visual storytelling, it becomes clear that a lot has happened to her in the last 14 years. She already knows her place in the world—even if she dreams of a different one.
In broader strokes, this first part of the movie is about the three Eva pilots learning what life can be like when your existence isn't defined by being an Eva pilot—and in doing so, reaffirming why it's important that they pilot anyway.
While all this characterization is going on, we also get a lot of the explanation left out in the previous film: namely what exactly happened over the past 14 years, what the state of the world currently is, and what the goals of Wille and Nerv are. It's refreshing to finally get a clearer picture of the events of You Can (Not) Redo, even if it took a nine-year wait.
