Synopsis

Osomatsu-san follows the misadventures of the Matsuno brothers, identical sextuplets who are well into adulthood but refuse to grow up. They are NEETs – Not in Education, Employment, or Training – perfectly content with bumming around and causing chaos.

Each brother has a distinct personality, which often clashes with the others and leads to ridiculous situations. The show revolves around their attempts, usually unsuccessful and often absurd, to find love, get jobs, and generally improve their lives.

Despite their best (or worst) efforts, the sextuplets remain stubbornly immature and unemployed, navigating everyday life with a healthy dose of slapstick comedy and bizarre scenarios. The core of the show is the brothers' chaotic dynamic and their struggles to function as responsible adults while retaining their childlike antics.Ultimately, it's a comedy about six identical brothers refusing to take life seriously.
