Koharu Utatane

is a former member of the dissolved Team Tobirama. She and her team-mate Homura Mitokado now serve as members of the Konoha Council.

Background
Under the guidance of the Second Hokage, Tobirama Senju, Koharu and her team-mates, Hiruzen and Homura, completed numerous missions and became close friends. When Hiruzen became the Third Hokage, Homura and Koharu became his councillors. With their years of experience, knowledge and their unending effort to make Konohagakure a better place, they eventually gained similar respect and social status as the Hokage himself.

During the Nine-Tails' attack on Konoha, Koharu was fighting alongside her team-mates and many other shinobi, attempting to restrain the beast. She was seen wearing an armour similar to that of Hiruzen.

Personality
Koharu is assertive and strong-willed, yet she always has Konoha's best interests in mind. She holds the belief that the group is more important than any of its individual members, which often clashes with the Third and Fifth Hokage's view. Like Homura, she is more militant than the Hokage she serves under, to the point of leaning towards Danzō's way of thinking. This became apparent when she and Homura supported the Uchiha clan massacre, believing it to be the most advantageous course of action for the village's sake. Later, they wanted to restrict Naruto Uzumaki's movements, and after Pain's defeat she agreed that Tsunade was partly to blame for Konoha's destruction. She has also been described as a collectivist as well a humble person.

Appearance
In her youth, Koharu was a beautiful kunoichi with dark eyes. Her hair is pulled back in a twin bun locked by a traditional Japanese hair pin with two pearls dangling off the side. She also had fringes that covered her forehead protector. Her armour consisted of a simple black outfit, fishnet tights with a skirt over it and regular shinobi sandals. During the Nine-Tails' attack on Konoha, she was seen in the same outfit as her team-mates Hiruzen and Homura, complete with a gauntlet on her right arm and mesh armour.

In her old age, she maintains her original hairstyle without the bangs. The pearls on her hair needle have also increased and tassels were added to the other end. Her earrings are also considerably longer. As a member of the Konoha Council, Koharu wears a simple long kimono, closed by an obi, a jacket, and a sash over it. Koharu has also taken to squinting, barely opening her eyes at any point in time.

Abilities
Her skills remain predominantly unknown. However, in the anime it was shown that she is highly perceptive, detecting an explosive tag hidden in a wall, extracting it, and noticing that the tag was decades old.

Chūnin Exam Arc
Koharu is first seen in the series at a meeting between the Konoha Council and the jōnin-level shinobi of the village. They discussed Hayate's death and the looming threat of Orochimaru. She tells them that they already have ANBU gathering information in other countries and that they shouldn't be too focused on Orochimaru as the enemy may use it to their advantage.

Search For Tsunade Arc
After the death of the Third, Homura and Koharu finds Jiraiya spying on women bathing, an action which Homura reprimanded him for. They then discussed the situation between Konoha and Suna which Jiraiya said he was fully aware of. Koharu then tells him that no one knows when another nation may try to invade them again. She then tells him that they need to hold an executive committee meeting but before that they needed to select a Hokage as trouble could come at the village from any angle. She then attempts to tell Jiraiya the decision that was made at a meeting that they held on the previous day, however Jiraiya cuts her off and declines the post that they were offering to him. Homura tells him that it had already been decided as he was the most eligible person for the post. Jiraiya however makes mention of another candidate that was possible even more qualified than he was. She then acknowledges the fact that Tsunade was in fact eligible for the post, but her location was unknown. When Jiraiya states that he will go and look for Tsunade, Homura insists that three ANBU accompany him, Jiraiya declines once again and says that there is no need to have him "followed" because he wasn't running away. He however did request to bring one person along with him: Naruto.

Trap Master Arc
When Tsunade learns that the village is rigged with explosive tags. Koharu and Homura volunteer to aid in the search and removal of the tags. Tsunade sends them to an abandoned section of the village where they find an explosive tag lodged in the walls of one of the buildings. Bringing this back as evidence to Tsunade, they also note that the tag was really old judging from how the seal was written on it.

Sai and Sasuke Arc
After Shizune becomes increasingly uneasy about how liberal Tsunade was with Naruto and the missions he went on that constantly put him at risk of encountering Akatsuki, she speaks to Homura and Koharu, who in turn, hold a meeting with Tsunade. Koharu tells Tsunade that Naruto was no ordinary boy, Homura voices that as such shouldn't be leaving the village at all and should have been kept under constant supervision. Throughout the whole meeting Homura remains predominantly neutral in the conversation. After Shizune states that as Kakashi was still recuperating so a interim leader would have to be selected, Koharu tells Danzō to enter the room. He suggest that someone from the ANBU be selected to lead the team to which Koharu agrees.

Twelve Guardian Ninja Arc
After Tsunade deploys a team of ANBU to capture Danzō and unknown assailant that he had been secretly communicating with they are captured and brought back to the village. During the interrogation Homura and Koharu intervene. She informs them that while Tatsuji had been passing information to Danzō, he was also relaying the same to them as well. She then tells that even though they are uncertain that Sora possess a special ability and that the people that attacked the Fire Temple may be after him as well.

Invasion of Pain Arc
When Tsunade tells Kōsuke to head back to Mount Myōboku and get Naruto after Pain invades Konoha, before he is able to leave, Homura and Koharu interrupt saying that she should leave Naruto where he was safe. Homura then tells Tsunade that according to Danzō, that the leader of Akatsuki was heading the assault and their target was Naruto. Koharu tells Tsunade that although she overlooked it last time, this time was different as this was the man that killed even Jiraiya. As Tsunade physically accosts them, Koharu demands that she let them go. Tsunade then tells them both that Naruto was a shinobi of Konoha and not a tool of the village. She also tells them that unlike Jiraiya and Hiruzen, and even Chiyo, they lacked faith and trust in the younger generation. After initially reacting with shock, they tell her to do whatever she pleased, giving up on trying to change her mind.

Koharu is not seen again until the conclusion of the invasion at a meeting of the country and village's heads. She informs the Fire Daimyō and his delegation that Tsunade was still in a coma and that they couldn't decide on a plan for the village when they didn't know when she would wake up. She also used the opportunity to lay partial blame on Tsunade for the invasion.

Five Kage Summit Arc
When Kakashi returns to the village from the Land of Iron, and informs them of what had happened and that Danzō had died, Koharu states that they'd have to hold a meeting to appoint a new Hokage immediately. She then told Kakashi that they had no choice but to nominate him for Hokage. Later at another meeting with the daimyō, as they are prepare to appoint Kakashi as the new Hokage, the meeting is interrupted by a ninja who tells them that Tsunade has woken from her coma.

She is later seen at a war council meeting that Tsunade calls. She tells them that foremost they need to acquire tools and provisions and that the forces would be split into a war division and support division. She then tells them to bring her a list of all the ninja in the village.
