Kamen Rider Ryuki, the 2002 Japanese tokusatsu series from Toei, gave its Riders Advent Cards that summoned weapons and abilities during Mirror World battles. Sword Vent is the card that calls a Rider's sword, and its short electronic sound became a familiar cue for fans who grew up with the show. Clips of the effect later circulated in fan edits, tokusatsu compilations and soundboards, where it is now reused as a quick shorthand for arming up, even by viewers who have never watched the full series.
