Kakashi Hatake, the Hokage (火影はたけカカシ, Hokage Hatake Kakashi) is episode 219 of the Naruto: Shippūden anime.
As the stone carver begins to carve Danzō's face in the Hokage Monument, he is told that Danzō is dead. Meanwhile, Kakashi takes Karin to the Konohagakure Intelligence Division to be questioned. Naruto gathers the Konoha 11 and tells them his decision to fight Sasuke alone, much to their frustration. After talking with the village's elders who agree that he should become Hokage, Kakashi wanders around Konoha, thinking about his future as a Hokage. Might Guy appears and challenges him to race. Kakashi ultimately wins the very close race and Guy congratulates him on becoming Hokage, claiming that from now on Kakashi will be too busy for their matches. However, Kakashi tells him that they will always be "eternal rivals" and that he is happy he is there, leaving Guy in tears. Later, as the Fire Daimyō is about to appoint Kakashi as the new Hokage, Guy bursts into the room and informs them that Tsunade has awoken from her coma. As the stone carver begins to carve Kakashi's head, he is once again stopped and informed that Tsunade will remain the Hokage, much to his frustration.
In the previous episodes, Karin's clothes were torn and bloody on her back. In this episode, her clothes are clean.
In the manga, the ninja who interrupted Kakashi's meeting with the feudal lord was not Guy, it was an unknown character not seemingly of great importance to the plot.
