What Is Rock Lee's Springtime of Youth?
The most successful Naruto spinoff is a joke at the main series' expense, drawn by an insider. Kenji Taira, who had worked as Kishimoto's assistant, created Rock Lee's Springtime of Youth for Saikyo Jump, Shueisha's magazine for young readers, where it ran from 2010 to 2014 and filled seven collected volumes. The premise is the whole cast redrawn as chibi caricatures, with Rock Lee promoted to hero and Naruto demoted to his straight man.
The manga's success carried it to television. Studio Pierrot's anime version ran from April 3, 2012 to March 26, 2013, for 51 episodes of two short segments each, with the original voice cast returning to play distorted versions of their own characters. In a detail that still startles fans, the series took over the TV Tokyo time slot vacated by Bleach, one flagship Jump anime handing its chair to another's parody.
The tone is sketch comedy rather than parody with teeth: Lee misreads every social situation, Neji suffers in drag, and the Fourth Great Ninja War era raging in the main series is treated as raw material for gags. Kishimoto's blessing, and his former assistant's byline, are why the fandom counts it as family rather than merchandise.
The spinoff family
Taira's career is a spinoff lineage of its own: after Rock Lee he drew the Sasuke chibi sequel, Uchiha Sasuke's Sharingan Chronicles, in the same magazine. The two series together form the official gag branch of Naruto publishing, and their small format volumes sit on the Library's shelf beside the Gaiden and the novels as the franchise's sanctioned side stories.
Collecting the gag shelf
Because Saikyo Jump aimed at children, Rock Lee volumes were printed as inexpensive, kid-sized objects, and English readers mostly met the series through the anime stream and Viz's digital release of the manga. A complete Japanese set of all seven volumes is the collectible form: modest books whose value to the shelf is that they complete the official Naruto bibliography.
