KoteIzu is the slash ship between Kotetsu Hagane and Izumo Kamizuki from the Naruto fandom.


Kotetsu and Izumo are childhood best friends and partners, they are rarely(if ever..) seen without the other and hangout during and out of work. They are the front gate guards of Konohagakure and Tsunade's assistants.

Compared to Izumo, who loves to work and takes his job as a guard seriously, Kotetsu is more carefree and prefers to run off on the job to eat syrup(his favorite food). Despite their different personalities, they work well together and have great teamwork, as evidenced in their battle against Kakuzu and Hidan.

When Kotetsu runs off again during work shift to eat syrup in the Jōunin Standby Station, Izumo crashes into the room angrily and drags his partner back to work.

During the Chūnin Exams, they disguise themselves as genins together to assess the strength of the participating genins. They are later seen together(as chūnin) watching the genins take their test to make sure no one's cheating and later observing the preliminary matches.

They appear together again, when they discover Sakura knocked out after Sasuke leaves Konoha and inform the fifth Hokage.

Kotetsu and Izumo are teamed with Shikamaru and Asuma to hunt down an Akatsuki duo. They manage to track them down and by working together, they manage to land a hit on Hidan. After the ensuing fight between the team and Akatsuki duo which results in Asuma's death, Kotetsu and Izumo are seen attending his funeral together.

In Naruto Shippuden episode 157, they face off against Kakuzu again and launch a surprise attack. They succeed in restraining Kakuzu with the help of Choji and some other nins and binding him.


  • Guard duty
  • Carrying out a broken chair from Tsunade's office (which landed on Izumo apparently)
  • Playing cards
  • Helping to rebuild the village after Pain's attack
  • Allied Shinobi Forces


They are a common background ship for other popular ships.

Kotetsu and Izumo are partners-in-crime and Izumo is forced to go along with whatever crazy idea Kotetsu comes up with. Izumo is more reserved and fights strategically while Kotetsu prefers to just rush in, blades swinging.
