Kishimoto has admitted he made no plans in regards to the development of "Naruto"s story developments. For example, when introducing Sasuke, the character says he wants to kill a person named "Itachi" who he had to redesign a number of times. By this time, Kishimoto only thought that Sasuke's brother, Itachi, had done a wrong deed in the past but was not certain of what was exactly. By volume 16 of the series which featured Itachi's actual introduction, Kishimoto decided Itachi was an agent working for Konohagakure to kill all members from the Uchiha clan except Sasuke. This is later revealed in volume 43 of the manga. Another one was the revelation that the late Minato Namikaze would be Naruto's father. When Kishimoto had the idea that Minato would be Naruto's father, he started adding hints of that to the reader such as giving the Hokage mountain from Konohagakure spiky hair similar to Naruto's.
