Izumo Kamizuki

is a Chunin from Konohagakure. He spends most of the time with his partner Kotetsu Hagane.

Part I
Izumo and Kotetsu first appear disguised as Genin, trying to convince those planning to take part in the Chunin Exams not to bother. Team 7 recognizes that they have cast a genjutsu on the area, prompting them to give up in light of the group's skill. They then act as examiners in the first test. When Tsunade becomes Hokage, Izumo and Kotetsu start doubling as her assistant and as guards to the front gates of Konoha. The anime indicates that they are easily ignored or duped by those using the Transformation Technique while on the job.

Part II
Izumo and Kotetsu are assigned to a Niju Shotai team with Asuma Sarutobi and Shikamaru Nara. Their mission being to find members of Akatsuki, they do just that. The team tracks an Akatsuki duo to a bounty station, where Izumo and Kotetsu stab Hidan during a sneak attack. When Hidan survives, they pull back and watch Asuma fall prey to Hidan's jutsu, unable to help him. They instead engage Hidan's partner, Kakuzu, but are easily captured and must be rescued by Raido Namiashi and Aoba Yamashiro.

Abilities
During the battle with Akatsuki member Kakuzu, Izumo uses Water Release: Syrup Capture Field to blanket the ground in a sticky syrup that immobilizes Kakuzu, and Kotetsu attempts to attack the immobilized Akatsuki member.
