“Hiashi’s general personality is very stern and strict, as he assigned both his daughters arduous training, and rarely compliments their performance. This stern nature is especially true with Hinata; when she was assigned to Kurenai, he told her that he was unconcerned about the possibility that she would die, saying that the Hyūga clan had no use for a weak successor.
However, he truly cares for them as part of the family. This is primarily seen in his hesitation to allow his brother to die to protect the secret of the Byakugan. Similar to Hinata, he did not view Hinata’s talent or potential weak, but her drive to succeed as the successor of the Hyūga clan. As the series progressed and she started to show her true dedication, he began to openly cheer her on.”
