Most of the Matsuno household consists of six identical siblings: the self-centered leader Osomatsu, the manly Karamatsu, the voice of reason Choromatsu, the cynical Ichimatsu, the hyperactive Juushimatsu, and the lovable Todomatsu. Although each of them is over 20 years old, they are extremely lazy and have absolutely no motivation to find a job, choosing to live as NEETs instead. In the rare cases where they attempt to seek employment and somehow manage to secure an interview, their distinct personalities typically result in their quick rejection. From attempting to pick up girlfriends to searching for the ideal job, the daily lives of the Matsuno brothers are never dull as they embark on all sorts of crazy, and often outright bizarre, adventures. While they desperately look for a way to improve their social standing, it will not be possible if they cannot survive the various challenges that come with being sextuplets!
