The somewhat precocious and sadistic girl 'Mitsuba', the somewhat lecherous muscle girl 'Futaba', and the somewhat mysterious girl 'Hitoha'. Better known as the (mischievous) "Marui Sisters", this is the story of how these three triplets go about their days in Class 6-3 with their cute yet wild antics.
