Great Teacher Onizuka began as a Japanese manga by Toru Fujisawa in the late 1990s and was adapted into a popular anime series in 1999, following former delinquent Eikichi Onizuka as he becomes an unconventional teacher. Short dialogue clips from the series have long circulated among anime fans, who reuse memorable classroom exchanges in compilations, edits and reaction videos. This Murai clip fits that pattern, offering a recognisable piece of the show's school setting for fans who already know its characters and humour.
