だってばよ
Dattebayo
Naruto's sentence-final verbal tic — an emphatic "I'm telling you!" with no stable English carrier: 642 occurrences in our record, absorbed case-by-case by the manga translation. The anime dub's "Believe it!" was its own invention.
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.
忍道
Nindō
One's personal "ninja way" — 忍 (shinobi) + 道 (way/path, the same suffix as 武士道 bushidō). VIZ's rendering wandered from "NINDO" through "SHINOBI SKILL SET" before settling on "MY SHINOBI WAY."
忍
Shinobi
The in-world word for ninja — the character 忍 means "to endure." VIZ keeps the Japanese term, one of the manga's earliest untranslated loanwords.
