Kishimoto cites The Matrix (one of his favorite movies) as an inspiration for their outfits. He has also cited Yoshihiro Togashi as one of his favorite manga authors, while the manga Sasuke by Sanpei Shirato inspired Kishimoto in the developing Sasuke Uchiha. Kishimoto has also cited other influences such as Takeshi Kitano and Quentin Tarantino. He also mentioned Michael Bay's technique "of shooting a scene against the background light" but found it difficult to make. Another technique inspired by Jackie Chan's films he used in the Naruto manga is the "double-action"; in this action, a punch is shown in three different angles in order to give a big impact on the punch's strength. This was first shown in Naruto Uzumaki's battle against Haku. Kishimoto sometimes draws panels as intentionally confusing during fight scenes to add a sense of speed. On the other hand, Kishimoto commented that for the fights between Naruto and Sasuke, he added action from the top of the page to the bottom in order for them to be easier to follow. During the series' publication, Kishimoto got married and had children. The changes to his personal life affected the story as he made Naruto Uzumaki meet his parents, something the author wanted the character to feel based on his own experiences as a father. When drawing the characters, Kishimoto consistently follows a five-step process: concept and rough sketch; drafting; inking; shading; and coloring. These steps are followed when he is drawing the manga and making the color illustrations that commonly adorn the cover of tankōbon; the cover of Weekly Shōnen Jump; or other media. The toolkit he uses occasionally changes. For instance, he used an airbrush for one illustration for a Weekly Shōnen Jump cover but decided not to use it for future drawings largely due to the cleanup required. Masashi and his twin brother Seishi have been drawing manga together since early childhood; thus their styles are similar. As a result, each has been frequently accused of copying the other- not just artwork, but story elements as well. Seishi notes that the similarities are not intentional but are likely because they were influenced by many of the same things. Kishimoto has admitted he made no plans in regards to the development of Narutos story developments. For example, when introducing Sasuke, the character says he wants to kill a person named "Itachi" who he had to redesign
