Himawari is a cheerful, considerate girl. This also extends to strangers. Himawari is very mature and responsible for her age, often helping her mother with chores. At the same time, Himawari has a temper. She can become very violent when provoked. When her favourite plush was accidentally damaged by Boruto, she assaulted him. She usually has no memory of these outbursts. This display of aggression made her elder brother run away and hide from her and vow never to anger her again.
