Uchiha Sanako was the wife of Uchiha Madara and birthmother of Isana & Itama. She were the only Uchiha to have not awaken the sharingan, and barely engaged in battles unless it meant protecting her children.
She were not a fighter, offensive being her weak side, and she were not capable of powerful jutsu, only simple ones. Thus, she has a very minimal chakra level and were limited in her jutsu abilities, leaving her exhausted.
It was seen at one time, when assassins invaded the area around the home, with Sanako having a picnic with her children outside, it seemed she were able to perform the Jutsu "Fire Release: Exploding Flame Formation" once, driving & severely injuring the assassins away in one blow.
Sanako was mostly a housewife, and when she became pregnant the second time with Isana, she became ill right after. Even with her sickness, she continued to raise her children with deep love as her body grew weaker. Before they could even start speaking at nearly the age of 2, Sanako, unfortunately, had died. Before her death, Sanako gave Isana her necklace.
While the woman shared the best married years of her life in a private home with Madara, Sanako knew about his past and his relationship with Hashirama, and feared what he could be capable of.
However, it is rumored that Madara killed Sanako, and half his reasoning for destroying the world were because Sanako had died. Sanako belongs to Tsuukuro on DA #uchihaoc#narutooc#notmyart#artisbyTsuukuro
