Natsuhi

Natsuhi was a kunoichi of Hoshigakure and also the wife of Hotarubi and mother of Sumaru. Years ago, both Hotarubi and Natsuhi completed the star training of their village. After seeing the side effects of the training they stole the star to prevent further damage. 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. (Source: Naruto Wikia)
