The first episode is easily the most lurid. The SA aliens retain that motivation, but there is never another “staging” of those intentions like the one that turns up early on. I’m maybe two chapters short of caught up to the manga and the generic anime problem of sexualizing teenagers obviously remains, but I don’t think things ever get nearly as bad as the first episode or the water level.
