Ninkuu: Knife no Bohyou

Both anime are based on manga published by Weekly Shounen Jump. Also, Kishimoto has cited Ninku to be one of the major inspirations behind his Naruto. This can be seen in the backgrounds and abilities of the main characters: both are skilled ninja, who combine ninjutsu with martial arts. Both Fuusuke and Naruto can use the wind element, and they have similar abilities, such as the substitution and clone jutsu, as well as their own version of Rasengan. Both anime also have similar vibe and comedy.
