Natsuhi

is the wife of Hotarubi and the mother of Sumaru.

Background
They both had completed the star training. They stole the star after seeing the side effects of the training. They were caught by the Third Hoshikage and banished from the village, though the Hoshikage promised to stop the star training.

Hidden Star Village arc
She stole the star again, and Akahoshi took her son as bait. She retried the star, then tried to steal it once again later after Akahoshi forced her to give up the star. She fell for a trap laid by Akahoshi and was hit by kunai thrown by Akahoshi when trying to destroy the star. Akahoshi then implanted the star in his chest. Naruto Uzumaki fought Akahoshi and destroyed the star in the battle. As she died, Natsuhi performed a technique that allowed her chakra to take the form of her ghost. The chakra supported Naruto Uzumaki, allowing him to fly briefly during the battle.
