火影
Hokage
"Fire Shadow" — the strongest shinobi and leader of the Hidden Leaf Village; VIZ renders the title as "Lord Hokage." Inheriting the name is Naruto's declared dream from chapter 1.
忍
Shinobi
The in-world word for ninja. The kanji 忍 stacks 刃 (blade) over 心 (heart) and means "to endure" — VIZ keeps the Japanese term, rendering 忍者 as "shinobi" on nearly every page.
