The characters are born from repetition, from repeatedly thinking about them. I have their outline in my head. I become the character and as the character I visit the locations of the story many, many times. Only after that I start drawing the character, but again I do it many, many times, over and over. And I only finish just before the deadline.
Its not a story in which the characters grow up, but a story in which they draw on something already inside them, brought out by the particular circumstances. I want my young friends to live like that, and I think they, too, have such a wish.
I create women characters by watching the female staff at my studio. Half the staff are women.
The villains are all parts of me. For years I've been wondering what it would be like if all those negative elements were forced onto the main character's side. I can understand a character with that kind of anger.
