返る meaning return, but not in the way that you wanted to use it in that sentence (correct me if im wrong)
from what i understand, 返る is used as 'return' in cases such as "i returned to books to 82riceballs", "please return those tools", "he returned my pen" etc
imo, for that sentence, if she came from Chiba to begin with, you could use 帰る, you could also use 戻る(modoru), which also means return
i know that 戻る can be used to "i want to return to that time/place" but im not sure about returning objects

ummmm im not gonna do this word because i have no idea LOL

so ill just pass it onto the next person
