Himawari Uzumaki (うずまきヒマワリ, Uzumaki Himawari) is a young citizen of Konohagakure, a member of the Uzumaki clan, and a direct descendant of the Hyūga clan.
Despite her lack of training as a kunoichi, Himawari has shown considerable potential, being able to terrify her prodigious older brother when angry, and knock out her father with a single blow when she was a toddler.
At age 3 — stemming from her Hyūga heritage — Himawari subconsciously awakened the Byakugan in anger after her favourite toy was torn by Boruto. In the anime, her grandfather, Hiashi, openly expressed how impressive it was for her to awaken it at such a young age.
When activated, her normally blue eyes take on the white and featureless appearance characteristic of the Byakugan. With it, she possesses a near 360° field of x-ray vision (except for a small blind spot at the upper thoracic vertebrae), see through solid surfaces, and can even clearly perceive the chakra pathway system. Despite no prior training for it, she was able to quickly adjust to its powers, make effective use of them.
Himawari can subconsciously make use of the Gentle Fist taijutsu. This allows her to surgically inject chakra into an opponent's tenketsu through her various strikes to internally damage her target or manipulate their chakra pathway system with just minimal contact. When using this in unison with her Byakugan, according to Hinata's assessment, a single strike from her was precise and strong enough to leave a person unconscious for an entire day, and in anime was able to knock out a tailed beast as well. Himawari also showed deceptive strength and speed, able to knock Boruto out of a room.
