A preview trailer for this summer's TV anime series Mitsudomoe, which is being adapted by studio Bridge, based on Norio Sakurai's gag manga about the comedic misadventures of the Marui triplets of sisters in sixth grade: the precocious and sadistic girl Mitsuba, the lecherous muscle girl Futaba, and the mysterious girl Hitoha. Better known as the (mischievous) "Marui Sisters", this is the story of how these triplets go about their days in Class 6-3 with their cute yet wild antics. (based on AniDB synopsis)
