Uchiha Mikoto

Uchiha Mikoto (うちはミコト) was a jonin level kunoichi of Konohagakure's Uchiha clan. She was the wife of Uchiha Fugaku. Including the mother of Itachi, and Sasuke. She was also the best friend of Naruto's late mother, Uzumaki Kushina. And lastly she is the mother in law of Haruno Sakura, and the grandmother of Uchiha Sarada.

Background
Mikoto was born on the day of June 1st to two unnamed parents. Her childhood is a complete mystery as well. However when she became best friends with Kushina is unknown. After marrying Uchiha Fugaku upon adulthood, she settled down to become a housewife, raising their first son Uchiha Itachi. Upon learning that she was pregnant with her second child, Mikoto told Itachi that she wasn't sick at all. She happily told him that he would be a big brother now. When she was pregnant with her youngest son Uchiha Sasuke, she happily believed and hoped she would have a girl. But she became surprise when Itachi told her that her younger child would be a boy. Mikoto became surprised when it had also started snowing outside after she and Itachi walked out of the hospital, while walking home, she told Itachi that his younger sibling would be born in the summer. When Sasuke was born, Mikoto was surprised that Fugaku already had Hiruzen's blessing to name their youngest child after Hiruzen's father.

Three months after Sasuke's birth, just before her best friend Uzumaki Kushina gave birth. Mikoto met with her on the streets by introducing Sasuke to her, and Sarutobi Biwako who happily noted that they had named him after the Third Hokage's father. Mikoto told the two older women that having Sasuke be named after the Third Hokage's father will make him grow up to be a great shinobi just like his namesake. Mikoto then asked Kushina if she had already picked a name for her child, since her due date is today. But Mikoto was surprised when Kushina told her that her child's name will be Naruto.

She agreed with Kushina's hopes that Sasuke and Kushina's only child would become best friends in the future, and after Kushina asked whether or not childbirth was painful, Mikoto laughed, having found the one thing that Kushina was seemingly afraid of. She then waved goodbye to Kushina and started to walk back home. When she got home, she played with Sasuke, while Itachi was eating dinner. When Itachi asked her if Minato was having a child of his own. Mikoto confirmed him that Minato and Kushina are having a child. But Mikoto excitedly wondered what gender Naruto would be after she spoke with Kushina. She then told Itachi that she was going out, and to look after Sasuke since Fugaku was at a meeting.

When Kurama attacked the village, Mikoto was no where to be found. What she was doing when the beast attacked was currently unknown. After Kurama was stopped, Mikoto went to the hospital to check on Kushina's newborn son, Uzumaki Naruto. By being greatly saddened for the loss of her dear best friend, and learning that her friends' only son is an orphan. After moving to the corner of the village, as Fugaku was going to teach Itachi the Great Fire Ball Technique. Mikoto told Itachi not to stay out too long, and to come back when dinner is ready. When Itachi enroll at the Ninja Academy, Mikoto was present at the ceremony. Once Mikoto witness Itachi's report card, she was happy for her son. Upon learning that Itachi was graduating a head of his class because he learned the Shadow Clone Technique, Mikoto was very happy for him.

When Sasuke was a toddler, Mikoto and Fugaku offer for him to come with them when they see her parents. However she was surprised when Sasuke said he will train with Itachi. She then gave more food to her husband and son. When she came back home, Mikoto was surprised when Sasuke told them that Itachi let him sleep outside.

7 years later when Itachi had enter in the ANBU, while Sasuke had enroll at the Ninja Academy. She treated Sasuke's injuries while he was struggling with the shurikenjutsu. As she sat down with her son as he had a day off, she told Sasuke not to push his body too hard. She even told Sasuke that times have changed since Itachi became a shinobi. Mikoto also put medicine on Sasuke's cheeks one day, but was sad when he walk away afterwards. A week later, Mikoto was seen leaving with the rest of of her clan after having a meeting.

While she was at home washing dishes. Sasuke told her how he felt about Fugaku and Itachi. She was happy when Sasuke told her that Fugaku was proud of him. However when Sasuke felt that Fugaku neglects him, Mikoto assured him that Fugaku does care about him. As Sasuke asks her why it's always about Itachi, she tells him that even though he and Itachi are different he is still Fugaku's son. She then told Sasuke that when she is with Fugaku, he talks about Sasuke all the time. When Fugaku was in the kitchen, Mikoto smiled as Sasuke told him that he will master the Sharingan someday because he is his son. As Sasuke was leaving for the Ninja Academy, Mikoto gave him his lunch one last time, and offer to help him with the shurikenjutsu. She then saw Sasuke off, and told him to have a great day.

Once the Massacre of the Uchiha clan was being carried out, Itachi confronted her and Fugaku. While being in a dark room, she knelt alongside her husband, putting up no resistance. When their son tried to explain himself, she simply told him that she understood from the start before allowing a distraught Itachi to kill them. This would later prompt Sasuke to avenge her death along with the rest of the clan.

Personality
Mikoto was described as a very gentle and kind woman, but one who could also be stern and strict when she neccessary needed to be, as seen when Itachi came back from the Ninja Academy, and she stopped Sasuke from bothering him, saying that he had homework. She loved and cared about her sons deeply, and knew how to help them with their problems. Mikoto cared deeply for her husband as well, holding a high respect for him, and understanding the importance of his position as the Uchiha Clan leader. She was always a dutiful and loyal wife who allowed Fugaku to hold authority in the household. She also gave Sasuke good advice, trying to reassure him about his ever distant brother Itachi. She was a very good mother, seeing as how Sasuke was able to talk to her much more easily than his father. At one point, in order to cheer Sasuke up, she told him that whenever she and Fugaku were alone, Sasuke was all he talked about.

Although she was Itachi's mother, she like other clan members, stood on the side of Fugaku, and the Uchiha Clan while not supporting the plans of Itachi and Shisui to diffuse the uprising. As their attempts failed, she seemed to know what terrible actions Itachi might take, even before the duo's final resort was sabotaged and Shisui's resulting death arose the other clan members' suspicions. But regardless of that, she still cared deeply about her eldest son, offering comforting words before allowing herself, and her husband to be killed by him without resistance.

In the anime, Mikoto appeared to be aware of Uzumaki Naruto's identity as Kushina and Minato's son. Since Naruto has Kushina's last name, and bears a striking resemblance to Minato. On the evening before Naruto was born, a happy Mikoto even wondered what gender Naruto would be after she spoke with Kushina. Even though she knew who Naruto was, she made no attempt to take part in Naruto's life to help fill the hole left by his dead parents. This was likely due to the suspicion that grew around the Uchiha following the Nine Tails's attack on Konoha, as the village elders (correctly) believed that an Uchiha had been in control of the Fox. Mikoto's absence in Naruto's life was likely to avoid any connection between the Uchiha, and the Nine Tails, as Naruto was current Kurama's Jinchuriki.

Appearance
Mikoto was a fair skinned woman with long, black hair with bangs hanging on either side of her face to roughly frame her cheeks and black eyes. She wore a simple dark purple blouse with a red plum skirt, and a light yellow apron over it. Back when Sasuke was only an infant, she was shown to be wearing a brown blouse similar to the purple one she wore, a dark purple skirt, blue shinobi sandals and the bangs on either side of her face were shown to be considerably longer.

Abilities
While little is known of her career as a kunoichi, while she was on active duty. She held the rank of jonin, a testament to her great skills. In the anime, she offered to help Sasuke with his shuriken training, which could imply that she was competent with shurikenjutsu.

Fourth Shinobi War arc

 * Tsunade's Infinite Tsukuyomi dream

In Tsunade's Infinite Tsukuyomi dream, the Uchiha Clan Massacre never happened. This left Mikoto to be still alive so can raise Itachi and Sasuke. During Sasuke's childhood, when he enrolled into the Ninja Academy, Mikoto met up with Kushina and her family, where Naruto was happily introduced by Minato.

Quotes

 * Times have change
 * When we're alone and no ones around. The only one he talks about is you.
 * (Last words) "We already now Itachi"

Uchiha Fugaku
She loves her husband and understands his job as the leader of the Uchiha clan.

Uchiha Itachi
Prior to the massacre, Mikoto was very close to her eldest son, Uchiha Itachi. As a child, Itachi would often ask her where his father was, and Mikoto would tell him that he was at a clan meeting. She would always warn Itachi not to eavesdrop on his father's meetings. Once Itachi entered the Ninja Academy, Mikoto was strict with Itachi's schoolwork, even telling Itachi that he and Sasuke can't play together until his homework was finished. When Itachi turned thirteen, he stopped eating dinner with his family completely, which made Mikoto very sad. Despite asking him to come eat dinner with the family once in a while, she tolerated his absence. She brought Itachi's dinner tray to his bedroom most nights, which Itachi always thanked her for. Mikoto may have been one of the few people who could tell what Itachi was thinking. Whereas Fugaku and Sasuke often seemed at a loss with him, and in Sasuke's case, almost totally oblivious to his brother's problems due to Itachi's desires not to worry him. When he decided to go through with the massacre of the Uchiha Clan, Itachi took the responsibility of killing his mother, who had accepted his decision to side with the village over the clan, telling him that she had known from the start what his choice would be. Itachi hesitated to kill his parents, with his body shaking and his face being unreadable. As tears Tears ran down his face, he promised Mikoto that he would take care of Sasuke before killing her.

Uchiha Sasuke
Mikoto's youngest son, Uchiha Sasuke, talked and spent time with his mother whenever he could. Sasuke was a quiet child who loved his mother dearly and shared a close relationship with her. When Sasuke was an infant, Mikoto would always hold him and play with him. She was the one who often comforted him when he felt that he was being neglected by his father, and she was always quick to assure him that he was well-loved by the both of them. One time, in order to cheer him up, she secretly told her son that he was the number one topic his father talked about when they were together.

Uzumaki Kushina
Mikoto was seemingly close friends with Kushina. Mikoto has been shown happily presenting a newborn Sasuke to an expecting Kushina, who at first confused him for a girl. On instinct, Kushina almost told Mikoto when Naruto would be born despite the secrecy surrounding her pregnancy due to her seal on the Kyuubi weakening during the period. Though the two have not often been seen together, they seemed to trust and care for each other greatly, and after Kushina and Minato's deaths, Mikoto is seen looking through a hospital window at a newly orphaned Naruto in grief. Tensions between the Uchiha and Konoha were rising during this period, but the two still managed to maintain their friendship. It is unclear whether or not Fugaku shared his warmth toward the Uzumaki family, though they clearly sought peace between the two groups, and may even have achieved it if not for the untimely deaths of the Hokage, and his wife.
