Sumire’s background is unknown as she had a very limited appearance in the series. Very little is known about her, like the fact that she is a happily married woman with two children hailing from the Land of Fire and enjoys traveling. She first appeared in episode 36 of Naruto Shippuden, titled The Fake Smile.

​​She first appeared in Naruto Shippuden's Tenchi Bridge Reconnaissance Mission Arc. She goes to the same hot spring as the new Team 7 of Konohagakure (Village Hidden in the Leaves), made up of Naruto Uzumaki, Sakura Haruno, and Sai, and is led by Yamato, in the episode. She and the other women in the hot spring laughed at Naruto's boisterous argument with Sai in the men's spa, which made Sakura feel embarrassed.

This is the only instance Sumire ever appeared in the Naruto series so far. Based on this minimal appearance, Sumire is believed to be alive and well until any additional piece of information comes to light suggesting otherwise.

Sumire never had the opportunity to fully express her individuality in the series, and she had no vital roles. Her sparse appearance suggests that she enjoys exploring new places and taking long soaks in hot springs.

Sumire was just seen in the hot springs so all her attributes are unknown. From her limited appearance, it seemed that she has short, neck-length blue hair. She also has bangs that cover either side of her face.

Sumire is a traveler from the Land of Fire. She lacks battle tactics and skills because, according to the facts at hand, she did not go through the necessary training to become a shinobi. Even if she does have any special skills, nobody knows for sure.
