Sarutobi Biwako

Sarutobi Biwako (猿飛ビワコ) was a citizen of Konohagakure, and the wife to Sarutobi Hiruzen. She is also the mother to Sarutobi Asuma, and the Grandmother to Sarutobi Konohamaru and Mirai.

Background
In the anime, it was shown that a young Biwako lived in the newly founded Konohagakure, where she attended the Ninja Academy. One day, she fell down in front of it and was comforted by Uchiha Madara, whose look frightened her deeply. Senju Hashirama, however, managed to calm her down by giving her a flower he received earlier.

Biwako and her husband met with Uzumaki Kushina and Namikaze Minato shortly before Kushina was to give birth. Because Kushina was a jinchuriki, Hiruzen thought it best for Kushina to give birth at a secure location where Minato could maintain the seal, guarded by ANBU and with Biwako and Taji as her midwives. While they were on their way to the location, Kushina stopped to speak with Uchiha Mikoto who had just had her own baby. Biwako was pleasantly surprised that Mikoto had decided to name the boy after her husband's father but prompted Kushina to leave, warning her as they left that her delivery was top-secret.

When Kushina went into labour, Biwako had to calm a hysterical Minato down as he maintained the seal, noting that women were a lot stronger than men. No sooner after Biwako delivered baby Uzumaki Naruto to be seen by Kushina, for the first ime. She was struck down by Uchiha Obito who had also killed all the ANBU stationed outside.

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 Namikaze 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 the newborn away from his father.

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 a purple kimono-like dress, along with a white haori and sandals. As a child, Biwako's hair was shoulder-length with a pink flower hair band, she wore a green kimono, light-brown long sleeves shirt with a loquat on the back, red pants and sandals.

Confining the Jinchuriki arc
Biwako and her husband, Sarutobi Hiruzen met with Uzumaki Kushina and Namikaze Minato shortly before Kushina was to give birth. Because Kushina was a jinchūriki, Hiruzen thought it best for Kushina to give birth at a secure location where Minato could maintain the seal, guarded by ANBU and with Biwako and Taji as her midwives. While they were on their way to the location, Kushina stopped to speak with Uchiha Mikoto who had just had her own baby. Biwako was pleasantly surprised that Mikoto had decided to name the boy after her husband's father but prompted Kushina to leave, warning her as they left that her delivery was top-secret. When Kushina went into labour, Biwako had to calm a hysterical Minato down as he maintained the seal, noting that women were a lot stronger than men. No sooner after Biwako delivered baby Uzumaki Naruto to his parents. She struck down by Uchiha Obito who had also killed all the ANBU stationed outside.
