His first version of Naruto, drawn in 1997, was a one-shot story about fox spirits; his final version, which debuted in Weekly Shonen Jump in 1999, quickly became the most popular ninja manga in the world. The series would also spawn multiple anime series, movies, novels, video games and more. Having concluded the series in late 2014, Masashi Kishimoto kept himself busy penning continuing adventures in the Naruto world, including the manga Naruto: The Seventh Hokage and the Scarlet Spring and the story for Boruto: Naruto the Movie, both of which focus on the title character’s son, Boruto.
