At the Foundation, Kakashi meets a boy who uses Wood Style, a jutsu that only First Hokage Hashirama was capable of using. Kakashi goes to Third Hokage Hiruzen's library to seek answers and discovers records regarding Hashirama's cells.

While pursuing Orochimaru, Kakashi wanders into a village inhabited by the Iburi Clan, a group of people with the unique ability to turn into smoke. Kakashi is soon captured and learns that the villagers all serve under Orochimaru.
