Kamen Teacher is a high-impact action drama manga set in a lawless high school system where violence rules and teachers are powerless, following Gota Araki, a former delinquent turned educator who dons a mask and uses brutal martial prowess to restore order, dragging students and staff alike into confrontations that blur the line between discipline and domination as underground gangs, corrupt authorities, and rival schools escalate the conflict into all-out warfare. As Araki enforces his own brand of justice, the story explores themes of authority, rebellion, redemption, fear, and the morality of violence as a teaching tool, delivering raw intensity, exaggerated action, and a provocative look at power within broken institutions. Blending action, delinquent, and school drama, the series built a cult following for its outrageous premise and relentless pace, later spawning sequels and a live-action adaptation. Also known as Kamen Teacher manga, 仮面ティーチャー, Masked Teacher, Kamen Teacher drama, Tooru Fujisawa manga, Gota Araki, delinquent school action, violent teacher manga, and rebellion school series.
