The oldest and leader of the sextuplets, as well as the best fighter in the group. In the 1993 one-shot story Osomatsu-kun Grows Up, he has become a typical salaryman and is unmarried. His name comes from osomatsu (お粗末), which means lame or ill-prepared in Japanese.

The would-be hijinks of the mischievous Matsuno sextuplets are hijacked from episode one by colorful buck-toothed con man Iyami and Chibita, his bald munchkin sidekick. Nearly every episode is a standalone comedy cavalcade with the above cast as well as other quirky locals who show up in a number of different roles as the series shifts effortlessly between time periods and genres, but in most cases, Iyami and Chibita are front and center as partners in crime, a couple of sad sacks scraping by but carrying out scammy schemes in order to get rich quick.

Midori Katou is a Japanese actress and narrator who is most famous for the role of Sazae Fuguta from the long-running family anime Sazae-san. She is also known for voicing Yoshiko in Sally the Witch and Osomatsu Matsuno in Osomatsu-kun (1966).

The Matsuno sextuplets (leader Osomatsu, wannabe tough guy Karamatsu, straight man Choromatsu, cynical Ichimatsu, cheerfully stupid Jyushimatsu and lovable spoiled Todomatsu) are now in their 20s, still living together in the same house as NEETs. Their neighbors still include such eccentric characters as fish market idol Totoko, loud bucktoothed troublemaker Iyami, tiny rival Chiba, wacky inventor Dekapan, and giant mouthed glutton Dayon. 
 
Join the Matsuno siblings as they overcome mundane hurdles in their daily lives, such as finding employment, figure out who should pay the bar bill, and who should get the extra pastry!
