In the 1st part you told us how Naruto was created. Now I want to talk about their speech pattern and how they talk. Let's start by Kakashi. He started very rude but he softened quite a bit after that.

Kishimoto : During the character creation phase, before the actual 1st chapter was released, I used to draw him like a Samurai. At that time, I didn't really know what his character would be like. I had this very stern and rude master image in my head so I gave him a very strict speech pattern. But after that I wasn't happy with how it turned out. I started thinking "A laid back master would be better, I guess."

So you started to think about his personality as the readers know it ?

Kishimoto : A laid back master seemed very funny to me.
But when Kakashi starts getting serious, he's getting very hot blooded ! That's why I like him like that. Little by little I changed his speech pattern and gave it a laid back touch, with a bit of kindness and even a bit woman-like.

Except Naruto and Kakashi, a lot of characters have a very definitive speech pattern. Did some characters gave you trouble with that ? or some speechs you remember more than others ?

Kishimoto : I'd say Orochimaru. I wanted him to give a very creepy androgynous vibe.
But since I wanted him to be a terrifying opponent, I wondered if that was really the way to go to make him sound strong.
Then I started thinking it was good like that, he's strong and creepy, and the creepyness kept growing and growing.
For Jiraiya I have him an incisive and energic speech pattern like in old kabuki plays.
And since, except him, there has been few characters who really like to talk, he makes everything more colorful.

When you create actual speeches and lines, what do you take care of ?

Kishimoto : I try to "bend" the sentence/line, to make it hermetic. I always do that.

Please tell us more about that, in details.

Kishimoto : Before the chapter rough, I write the dialogue properly and then change it. At first I write in a very simple way, that where everything lies.
Then I try to put up some originality in it but it's not easy.

What kind of changes are you talking about ?

Kishimoto : I rewrite the dialogues to make them more strange, more different. But I sometimes go way overboard and my assistants can't understand whatever the hell I'm writing.
In that case, I go back to the original simple dialogue.
