The Sextuplets


The Sextuplets are the Osomatsu-kun and Osomatsu-san series’ main characters and signature troublemakers.

Their family name is Matsuno and their birthday is May 24th.

In the Osomatsu-kun (Manga), 1966 TV series, 1988 series, and other related projects, they are 10 years old and are in the 5th grade.

In the Osomatsu-san (2015) anime, they’re in their 20s, unemployed, and still live together, showing that they haven’t grown up at all mentally. Each of them are also given more diverse personalities.


The “miraculous idiot.”

Osomatsu is the oldest of the sextuplets and their (often self-proclaimed) leader. He is also the best fighter out of them all.

As an adult, he continues to act as the self-proclaimed leader and is bull-headed and immature, but played as the more average of the brothers.



The “cool idiot.”

The second oldest. As a child, he is fickle and more tidy, but somewhat air-headed and impulsive as well.

As an adult, he is the cool guy wannabe who desperately wants girls to like him and think he’s cool, so he pays up airs around them all the time, only to fail miserably and end up being ignored.


The “reasonable idiot.”

The third oldest. He is described as clever yet selfish, and often cooperates with Osomatsu in their mischief.

In his adulthood, he is the clever and logical one of the sextuplets, and therefore, considered the most mature by their standards. However, Choromatsu still has his moments when he acts just as stupid as his other brothers, and is an otaku.


The “pitch-black idiot.”

Ichimatsu’s name refers to the first son, because “Ichi-” means one, but he is actually the fourth son. As a child, he is strong-willed and has more common sense.

By the time he’s become an adult, he is depicted as a melancholy, unmotivated loner who has an affinity for cats. He has a lack of social skills and difficulty in expressing himself to others.



The “of-another-dimension idiot.”

The fifth, second youngest son. He is outgoing and talkative, but is often taken advantage of due to his kindness.

As an adult, his head is always in the clouds, and he’s always seen with a smile on his face. He’s generally considered the silliest one of the brothers and has a permanent open mouthed grin.



The “good-at-letting-others-pamper-him idiot.”

The sixth and youngest son. He is often described as “carefree” and strongly dislikes baths. His catchphrase is often “Todo no tsumari,” meaning “in the end.”

His adult version is known for being effeminate as well as two-faced, acting sweet and innocent around strangers and sporting a cute smile as his default expression, but being manipulative and willing to insult and betray his brothers to make himself look better.
