Six adult sextuplet brothers share a roof, a striking resemblance, and a complete lack of ambition in this beloved comedy series. Each brother has his own distinct personality, from the self-appointed leader Osomatsu to the cheerful Todomatsu, yet all six remain proudly unemployed and unattached despite their best (and worst) attempts to change that. The show's humor comes from their chaotic, often absurd daily lives as they stumble through job interviews, romantic pursuits, and the particular madness of six grown men who simply refuse to grow up.
