The Hokage or known as Fire Shadow are the leaders of Konoha. They are generally the strongest in the village, although ideology and renown plays a large part in their being chosen for the position. Four shinobi and one kunoichi have gained this title so far, with another shinobi gaining the title of candidate Hokage.
Generally, the new Hokage is selected by the current Hokage upon their retirement, but if the old Hokage dies or is incapacitated before being able to do so, the Konoha Council and the Fire Daimyō council will meet and appoint a new Hokage together. Afterwards, the candidate Hokage will need to be approved by the jōnin of the village.
After being appointed, they are given the Hokage mansion to live in and have their faces carved out in the monument behind it. If the former Hokage is still alive, they will generally keep helping out, making the transition easier and more stable. The Hokage carry their title for life, even after retiring from active duty.
