In Naruto, created by Masashi Kishimoto as a manga in 1999 and adapted into anime in 2002, jutsu are the ninja techniques characters perform using chakra and often hand signs. Naruto Uzumaki and his rivals rely on them for clones, summons, and elemental attacks. Short activation sounds from the series spread widely in fan edits, AMVs, and meme videos because they instantly signal an anime power move, even when the footage underneath is from a game, a sport, or real life.
