Chisato Ayase, dispatched by the Secret Board of Education, fights evil teachers as Moretsu Mask, but the principals set a trap and put her in an electric shock chair. She withstands it with help from another mask, yet the headmaster sends a snake charmer, and she faints when wrapped in a large snake. The punishment continues with whipping, a shameful bikini, feather shurikens, and repeated electric shocks until she becomes a cripple.
