It wasn't out of the blue himawari was dorn with a sliver of kurama being passed down to her with the intense chakra control of a main branch hyuga and the fact that kurama was reborn from that sliver into a kit she has a friendship and an innate connection to him vs Naruto being a forced capsule for him to be locked away in kurama doesn't have the intense hate in him from the previous wars and what humans did to the Tailed Beasts cause he is a blank slate now that's why she is more proficient with controlling his chakra and doesn't go on rampages maybe read the new Manga before you try and downplay one of the most important moments in Ninja history thank you listening to my TED Talk.
