The Third Hokage, real name Hiruzen Sarutobi, has been the longest-ruling Hokage. He is a peace-loving leader, preferring nonviolent discussions to his advisers' more militaristic suggestions. Throughout the series, he acts as a source of wisdom to younger generations and is one of the few characters to treat Naruto Uzumaki as a person and not just the container of the nine-tailed demon fox.
