Koharu Utatane

is a former member of Team Tobirama, together with Hiruzen Sarutobi and Homura Mitokado. She and Homura now form the Konoha Council.

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

She holds the believe that the group is more important than any of its individual members. Because of this, she always tries to do what she thinks is the best for Konoha, even if it goes against her or the Hokage's opinion. She's also quite demure, but doesn't let this stop her from voicing her opinion. In fact, despite this, she's one of the few people able to put the Fifth Hokage to her place when she oversteps her authority. Like Homura, she's more militant then the Hokage she served under have been, and sometimes leans more to Danzo's point of view. This became most apparent when she and Homura supported the Uchiha Clan Massacre and later when they wanted to restrict Naruto Uzumaki's movements.

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.
