Sarada's character often develops a greater sense of self - awareness during time travel. In the past, she may see how her family and the village were shaped, which gives her a new perspective on her own life. For example, if she sees her mother, Sakura, as a young and determined kunoichi, it might inspire her to be more like that. Also, she may become more resourceful as she has to adapt to the different ways of the past. She can't rely on the modern technology or some of the ninja tools she is used to in her own time.
