Osomatsu-san Mr. Osomatsu
The original manga and "high tension comedy" TV anime centered on the Matsuno household, which has six naughty and mischievous sons (who are sextuplets). All of the sextuplets, including the eldest Osomatsu, are all in love with the same girl, Totoko. The original series followed the family when the sons were 10 years old. The new series, titled Osomatsu-san, will be the first television anime in 27 years, and it follows the characters after they've become adults.
