Masashi Kishimoto
Following the conclusion of "Naruto", Kishimoto became involved in the "Start of a New Era Project" commemorating the manga's conclusion and 15th anniversary. On the last page of the final chapter, "Weekly Shonen Jump" announced that a spin-off miniseries, also authored by Kishimoto, would be released in 2015. The series, "", ran from April to July 2015. Beyond this, Kishimoto was also heavily involved with two canonical movies, "" and "", as he personally supervised both movies, and illustrated several light novels. When asked by Boruto Uzumaki's voice actress Yūko Sanpei to continue making "Naruto" movies, Kishimoto stated that he was taking a break and could not physically do so.
Naruto
When he created "Naruto", Kishimoto looked to other "shōnen" manga as influences for his work and tried to make his characters unique, while basing the story on Japanese culture. The separation of the characters into different teams was intended to give each group a particular flavor. Kishimoto wanted each member to have a high level of aptitude in one skill and be talentless in another. He found it difficult to write about romance, but emphasized it more in Part II of the manga, beginning with volume 28. He introduced villains into the story to have them act as a counterpoint to his characters' moral values and clearly illustrate their differences. As a result of how the younger characters were significantly weaker than the villains, Kishimoto made the timeskip in order to have them age and become stronger during this time.
