Season 0 of Mr. Osomatsu premiered on January 29, 2016.

Season 1 of Mr. Osomatsu premiered on October 5, 2015.

The Matsuno sextuplets, stars of the classic series "Osomatsu-kun", are jaded 20-somethings looking for a job and love, but never seem to find it or make an effort to. How can they compare to their friends as kids who have had some degree of success, along with every other 20-something in the country? Featured alongside these tales of adult woe are fantastical stories of said characters in roles beyond their own abilities, from a murder mystery case to Edo period dramas.

Season 2 of Mr. Osomatsu premiered on October 3, 2017.

The sextuplets, after their successful first season, are back to the grindstone of perhaps finding societal balance...or maybe just slacking off and enjoying life through their empty wallets. Humorous topics such as self-doubt, mortality, and the ever-present inferiority complex are abound!

Season 3 of Mr. Osomatsu premiered on October 12, 2020.

After their unceremonious deaths and resurrections in the last season, the sextuplets are visited by two AI-powered robots who only claim to be in service to NEETs who need them. Do they have any ulterior motives? What's Totoko's long-time idol rival doing as a single mother? And what does an upcoming AI-generated comedy competition have in store for the brothers and their new helpers?

Join the Matsuno sextuplets and all the rest as they celebrate what will hopefully be a relaxing summer, if not for the fact that they're still broke and not even trying for employment.
