Origin
Hoshigakure no sato
Natsuhi (ナツヒ, Natsuhi) was a highly skilled and capable kunoichi, often praised by Akahoshi and the Third Hoshikage. Both she and her husband had completed the star training. Natsuhi was a caring and loving mother who cared greatly for her child and family. She also showed great love towards the village — going as far as to stealing the Star in order to assure that no one would suffer from the side effects of the training ever again. However, they were caught by the Third Hoshikage who 'banished' them to keep an eye on the village after promising to stop the star training. Natsuhi and Hotarubi begged the Third Hoshikage to tell their young son Sumaru that they died long ago and gave him Hotarubi's necklace as a gift for him. She had jade-green-coloured eyes and long violet hair. She wore the Hoshigakure flak jacket and shorts.

Naruto
Moments prior to Naruto Uzumaki's birth, a huge demon known as the Kyuubi, the Nine-Tailed Fox, attacked Konohagakure, the Hidden Leaf Village, and wreaked havoc. In order to put an end to the Kyuubi's rampage, the leader of the village, the Fourth Hokage, sacrificed his life and sealed the monstrous beast inside the newborn Naruto.
