Now let's talk about words. How did you came up with Naruto's "Dattebayo" ?

Kishimoto : I was looking for a brat like speech and I started from "Datteba" ( Roughly meaning "But I'm telling you that ..." )

So from the start, Naruto was supposed to have a verbal tic ?

Kishimoto : Of course. It's maybe a little simplistic when creating a character. But I like when a character has a definitive speech pattern and catch phrases.
That way the reader remember the character very fast from the way he's speaking.
Since I wanted the reader to be puzzled, maybe a little irritated, I gave Naruto a weird verbal tic.
