#amazon quartet
When we see Chibi Moon and the Sailor Quartet sent back to the future by Cosmos at the end of the manga, it is close to, if not the last, time she goes back to the 20th century. This is because it is only a few years after that that Usagi becomes pregnant with Chibi-Usa and when two instances of the same person from different points in the timeline meet, it puts both of their existences in jeopardy. So once she stops time traveling, what does Chibi-Usa’s life look like?
I believe that in the future, Chibi-Usa goes to a public school. She has become used to being a “normal” girl and there are several hints throughout the series that she actually prefers this to being a princess. However, despite what her preferences might be, it doesn’t change the fact that she is a princess and so her guardians, the Sailor Quartet, are enrolled in the same school as her and are even in the same class (much to the horror of several teachers as JunJun and VesVes are a dreaded prankster duo), in order to be there in case anything threatens their princess. (Besides, they’re all friends, so they’d want to go to the same school. Except maybe JunJun, but that’s more not wanting to go to school in general than not wanting to go to the same school as her sisters and Chibi-Usa.)
But what of Hotaru, Chibi-Usa’s best friend who Naoko Takeuchi imagined fighting together with Chibi Moon and the Quartet? Obviously she would be well out of school by now, but she’d probably still want to be close to her princess.
So how does she manage this? It all has to do with what we were given to be her dream for the future. She wants to be a nurse. So I think that in the 30th century, Hotaru is a nurse at Chibi-Usa’s school, just like Setsuna was at Usagi’s. Of course, Hotaru’s personality being different than Setsuna’s, she gets more embarrassed about all the male students who have crushes on her, but eventually she grows into the role.
Not that VesVes ever stops teasing her about her “harem.”
