Mr. Osomatsu Season 4 Teaser
There’s also a new visual:
Inspired by Fujio Akatsuka’s Osomatsu-kun manga, the current Mr. Osomatsu anime first premiered in 2015, with seasons 2 and 3 following in 2017 and 2020, respectively. There’s also an anime film, a live-action film and animated shorts.
Mr. Osomatsu is currently streaming on Crunchyroll, which sums up the third season like so:
The legend of the most famous sextuplets from Japan is back for the 3rd time!!!!!! There are even more new developments waiting around the corner this time?! In 2015 the TV anime “Mr. Osomatsu,” based on Akatsuka Fujio’s famous gag manga “Osomatsu-kun,” was created to commemorate the 80th anniversary of Akatsuka Fujio’s birth. The anime portrayed the sextuplets as twenty-somethings, NEETs, and virgins. Despite that, there was something lovable about the Matsuno sextuplets and the depiction of their daily lives, that caused a social phenomenon.
5 years later, the six are back again and ready to cause havoc in all the wrong ways yet again! And apparently, there’s going to be a new change with the Matsuno Family? That problematic show is back again!
