Development

The concept of No.6 was inspired by the September 11 terrorist attacks in 2001. Atsuko Asano watched the attack on television, causing her to ponder the nature of conflicts between an individual and the state, and wrote No.6 based around those themes. She has also described being influenced by the manga Banana Fish; highlighting the action elements, love between boys, and the relationship between a country and an individual as examples.
