Osomatsu-san 4th Season: Sou, Shuu, Hen

Imagine six grown men — identical sextuplets, all unemployed, all living at home, all absolutely insufferable in their own unique ways. That's the Matsuno sextuplets in a nutshell. This TV special is episode 12.5 of Osomatsu-san's 4th season, a bonus installment from Pierrot Films that slots right into the ongoing chaos of the series. Osomatsu's the lazy ringleader, Karamatsu thinks he's cool (he's not), Choromatsu pretends to have his life together, Ichimatsu is a walking rain cloud, Jyushimatsu is pure unhinged energy, and Todomatsu is the social-climbing youngest. Together they fumble through modern adult life with zero growth and zero self-awareness, and that's kind of the whole point. The humor here is sharp and satirical, poking at real societal stuff — dead-end job culture, social media vanity, the general existential dread of being a grown-up with nothing figured out. The animation style has this cool mix of retro and modern that keeps things visually interesting even when the brothers are just sitting around arguing about nothing. If you liked the absurd adult humor of Crayon Shin-chan, the slice-of-life comedy loops of KochiKame, or the dark workplace satire of Life Lessons with Uramichi Oniisan, this fits right in that wheelhouse. You don't need deep lore knowledge to jump in — just know that these six are disasters and the show loves them for it.
