Kuchiyose no Jutsu, also called the Summoning Technique, comes from Naruto, the long-running manga and anime series created by Masashi Kishimoto. In the story, shinobi use hand signs and a blood contract to call powerful animals and creatures to their side in battle, most famously Naruto summoning the toad Gamabunta. The technique and its distinctive sound became instantly recognisable to anime fans worldwide, and editors now reuse the clip far beyond the show itself, as shorthand for any dramatic arrival, unexpected help or over-the-top entrance.
