Biwako Sarutobi

was the wife of Hiruzen Sarutobi.

Background
She was one of the few people to know about the special circumstances surrounding Naruto Uzumaki's birth, acting as a midwife for Kushina Uzumaki. She was killed by Tobi shortly after Naruto's birth.

Personality
Biwako seemed to be as wise and intelligent as her husband, giving somewhat sagelike advice to Kushina about childbirth. She also seems to be very strongly opinionated about women, stating that they were far stronger than men because they can endure childbirth while men cannot. She also wasn't above reprimanding Minato for not focusing on keeping the seal intact during his wife's birth even though he was Hokage.

In the anime, Biwako was shown to believe that when a child is born the mother should be the first of the two parents to meet the newborn due to what they go through during childbirth as shown when Minato tried to meet Naruto and she turned him away.

Appearance
Biwako had long, brown hair which she kept in a high ponytail, dark eyes, slightly visible creases at the corners of her eyes and her mouth. She wore an outfit similar to that of the standard Hokage garb, with her under-gown being purple, along with sandals.
