Premise
The original Osomatsu-kun series followed the Matsuno brothers; Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu, who are all identical sextuplets who cause mischief. Mr. Osomatsu depicts the brothers as being ten years older than their original counterparts. All of the brothers have now grown up into lazy NEETs, with each brother having developed their own distinguishing personality. The series follows the brothers in their everyday lives.
