A couple years ago I watched an anime on Netflix, maybe 2015-2017...
It was about a girl whose mom I think worked at some government or intergalactic facility that kept an eye on aliens (who looked like regular people but just weren’t living on Earth).
The girl she works at maybe one of her family members cafe or restaurant on the beach. But she goes onto the site for some reason, and is prepared to be using one of their small battleships which apparently is an alien ship who only accepts a certain type of person, I think.
And it accepts her and so she learns how to do it, practicing and one day she has to fight other people and save her friends. Another girl, and maybe three guys on one big ship.
