## Synopsis
The fourth season of Osomatsu-san. 
The sextuplets run amok for a fourth time! Now adults in their 20s, they are still unemployed, undertrained, and single…but there’s something lovable about Japan’s most famous sextuplets. As a new chaotic adventure begins, what’s next? New friends? New trouble? And perhaps a new side to the sextuplets? Let’s all laugh together with these brothers who are beyond any hope.
