Natsu is a kunoichi from Konohagakure's Hyūga clan who worked as a maid and caretaker for Hanabi Hyūga. She's best known for keeping Hanabi on task—whether that meant discouraging playtime when Hinata was training or making sure her studies got done before she could run off and have fun.
Despite being generally kind and responsible in her duties, Natsu wasn't exempt from the prejudice that plagued the village. She shared most villagers' disdain for Naruto Uzumaki, even telling young Hanabi to shun him after they witnessed him being publicly scolded. It's a reflection of how widespread the anti-Naruto sentiment was at the time, affecting even the households of prominent clans.
As a Hyūga, Natsu has access to the Byakugan, the clan's signature dōjutsu. The ability grants her near-360-degree vision, x-ray sight, and the capacity to perceive the chakra pathway system in living beings—making her a capable fighter despite being primarily portrayed in a support role within the series.
