Sukeban is a Japanese term for a delinquent girl gang leader, a figure that became a staple of shojo manga, anime and live action stories from the 1970s onward, often shown in a long skirt uniform with a defiant attitude. Online, the archetype was revived through edits, cosplay and fan art that treat her entrance as an event in itself. Short intro clips like this one spread on soundboards because the music alone signals that character type, letting creators borrow decades of that rebellious image in a few seconds without explaining the reference.
