Izumo Kamizuki

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

Personality
Izumo is almost always seen alongside Kotetsu, and is characterized as being the more responsible and conscientious of the two. In Shippūden Episode 81, he angrily burst into the Jōnin lounge to drag his partner back to work. Similarly, in another omake, he admonished Kotetsu's lack of pride in his work when the latter complained that they were simply the Fifth Hokage's errand-boys or "gophers", before adding sagely that guarding the Leaf and the villagers was "the best mission you can get" as a shinobi.

Chūnin Exam arc
Izumo and Kotetsu first appeared disguised as Genin, trying to convince those planning to take part in the Chūnin Exams not to bother. Team 7 recognized that they had cast a genjutsu on the area, prompting them to give up in light of the group's skill. They then acted as examiners in the first test. When Tsunade became Hokage, Izumo and Kotetsu started doubling as her assistants 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.

Hidan and Kazuku arc
Izumo and Kotetsu were assigned to a Nijū Shōtai team with Asuma Sarutobi and Shikamaru Nara, their mission being to find members of Akatsuki. They managed to do just that. The team tracked an Akatsuki duo to a bounty station, where Izumo and Kotetsu stabbed Hidan during a sneak attack. When Hidan survived, they pulled back and watched Asuma fall prey to Hidan's jutsu, unable to help him. They instead engaged Hidan's partner, Kakuzu, but were easily captured and had to be rescued by Raido Namiashi and Aoba Yamashiro.

Abilities
During the battle with Akatsuki member Kakuzu, Izumo used Water Release: Syrup Capture Field to blanket the ground in a sticky syrup that immobilized Kakuzu, and Kotetsu attempted to attack the immobilized Akatsuki member. He is also seen using a large kunai-shaped sword that belong to his partner Kotetsu, while making a surprise attack against Hidan.
