Koharu Utatane

is the former teammate of the Third Hokage and Homura Mitokado. She is now a council member. Like Homura, she does not seem to think much of Naruto Uzumaki. She is currently one of Sasuke's Main Targets for revenge.

Background
Not much is known about her, but she was once a teammate of Homura Mitokado and the late Third Hokage, who were trained by Hashirama Senju and later Tobirama Senju. When she retired from her ninja career she went on to become a council member along with Homura.

Personality
Being an elder she believes that her beliefs are the right one. She seems to be a little bit extreme in her handling of the village, and is more keen on following Danzo instead of Tsunade, although both of them share the same politics.

When Naruto Uzumaki returned home, from a mission, involving Akatsuki, she suggested a restriction on the number of missions that Naruto could go on and limit his area of activity in Konoha since she was afraid that Naruto would become a victim of Akatsuki, and that Akatsuki would, after extracting the Nine-Tailed Demon Fox, become a threat to Konoha.

She and Tsunade are not on very good terms, as seen in the same episode and in Part II. She is not easily intimidated and is one of the few people who can put the temperamental Tsunade in her place when she oversteps her authority

She appears with the Third and Homura thinking on whether Orochimaru will attack the leaf village during the Chunin Exams.

In chapter 421 she is shown to not want Naruto to return to the village because she and Hamura have little faith that Naruto can defeat Pain.

Koharu tells Tsunade to leave Naruto at Toad mountain, claiming that Naruto would be safer there. Tsunade, however, refuses and grabs both her and Homura by there collars stating that Naruto is not a child any more and that he has the will of fire within him and claims that he is not a weapon to keep Konoha out of war. She tells them that unlike Jiraiya, Sarutobi and Chiyo of the sand, they don't have enough faith in the next generation. Koharu leaves and states that she can do as she likes.
