Nehelenia and Sailor Stars Arc

Hey y’all! I’m finally in the last season of Sailor Moon 😢 I re-read the Eternal manga recently and I thought the sailor scouts only tangled with Nehelenia the one time. In the Stars Arc she’s back. Are we going to get Galactica after we defeat Nehelenia (again)? I suppose we got more of her story in the anime as a way to flesh out the last season?
