Captain of the Konoha Medic Corps

This person is the captain of the Medic Corps of Konohagakure and the adoptive parent of Kabuto Yakushi. This was a lie created by Orochimaru in order to trick Root. As a result, Kabuto was the 'son' of Nonō Yakushi.

Background
After the Battle of Kikyō Pass ended, the captain found Kabuto amongst the dead enemies and brought him back to Konoha, and raised him as a son.
