The weirdest part about the whole human/alien thing is that the rest of the Ōtsutsuki clan shown in The Last appear completely human, no grey skin or horns whatsoever. Unless it's just the studio screwing up, it almost implies that Kaguya was the only alien and the rest of the clan are just Hamura's human descendants. But then that can't be right because some of them look to be about as old as he was (unless the aliens live a lot longer than humans do). Plus the databook makes it sound like Kaguya brought her whole clan with her to Earth, so it doesn't really add up.
