Synopsis
Satoshi Yabe, the newest faculty member at an elementary school, gets assigned as the homeroom teacher for class 6-3 and quickly realizes he's in for a surprise. The class is filled with disorder and unusual pupils, but the most troublesome are the mischievous Marui triplets. Mitsuba is cruel and remarkably grown-up for her age; Futaba is both indecent and extremely powerful; and Hitoha, often buried in her explicit books, is silent and foreboding. When the sisters become interested in Yabe, they begin bothering him with endless pranks. Misunderstandings and odd occurrences happen daily, making Yabe's school days anything but dull.
