List of Mr. Osomatsu episodes

When the sextuplet Matsuno brothers; Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu, learn that Osomatsu-kun is getting a brand new anime, they have doubts that their Showa era gags will cut it in a modern day anime. Thus, the brothers end up revamping themselves as a colorful bishōnen idol anime, in which they are all handsome idols with unique looks and personalities. However, after performing various feats such as saving the Earth from a meteor and somehow killing Totoko with their charms, the burden of being in a popular anime proves to be too much for the brothers' Showa era bodies to handle. Things soon get hectic when more characters appear in their rebooted forms, and the whole thing inevitably descends into a mishmash of parodies and blatant copyright infringement. Forced to go back to the drawing board, the brothers end up spending the next ten years doing absolutely nothing, at which point the actual anime begins.

After struggling to find employment, the Matsuno brothers wind up working at the shady Black Factory. Later, Osomatsu tries to take an interest in his younger brothers' lives, only to wind up being a nuisance to each of them.

A series of random shorts and parodies. A certain puppet-faced villain has trouble finding the right sextuplet to take revenge on, Dekapan becomes a superhero only to wind up in jail for indecency, Todomatsu tries to keep his pachinko winnings away from his brothers, Choromatsu has trouble getting a good night's sleep, Iyami winds up on the receiving end of a trick or treat, and an inappropriate quiz show is held at the public bath.

The Idol Matsunos participate in various activities that serve no purpose other than to promote a dubious health product. Meanwhile, the actual brothers become Sentai heroes to help Choromatsu, only to find themselves helpless at the sight of a social barbecue.

Choromatsu is worried that his brothers are depending too much on their parents. All of a sudden, their parents got into a fight which ends in them filing for divorce. Wanting their parents to stay together, the Matsuno sextuplets somehow participate in an interview to let their parents choose which child should they take care of. In the next story, Osomatsu is curious why Totoko suddenly invites him to her room, only to discover everyone else has been invited as well.

Karamatsu is taken hostage by Chibita, who demands the Matsuno brothers pay off their tab for his oden stand, only to find the brothers don't really care about him. Later, the family's pet cat becomes injected with a serum that allows it to speak human language and read people's minds, exposing Ichimatsu's true feelings.

Osomatsu plays a "calming detective" who calms down people working on murder cases with his buffoonery instead of actually solving them, mush to the dismay of the serious Detective Todomatsu. Back in reality, the Matsunos try to help Totoko become more popular as a fish idol.

While discussing his career plans, Karamatsu somehow winds up as Chibita's apprentice at his oden stand. Later, Jyushimatsu suddenly starts acting more calm compared to his usually hyper self, with the brothers learning that he has fallen in love with a girl who actually enjoys his antics. However, he is rejected after asking her out, as she is due to move, but the brothers encourage him to see her off as she leaves.

Osomatsu and Totoko host an end of year special broadcast, looking back on previous episodes to determine which of the brothers is the biggest loser.

The first segment features a drama about a down-on-his-luck salaryman named Sanematsu who faces hardships from his co-workers, but does what it takes to care for his sextuplet brothers, who are all part of his imagination. The second segment follows genderbent versions of the Matsuno siblings as they get into arguments with each other over guys. Back in reality, Choromatsu becomes disgruntled with Osomatsu after he interrupts his "private time", which soon leads to the rest of the brothers arguing with each other.

The brothers all catch colds, with whoever's left healthy causing a lot of trouble while trying to take care of the others. Later, the brothers question Todomatsu about all the things he hasn't told them about his personal life. Afterwards, Choromatsu plays the role of a paranoid vice-principal overly worried about plans for his school's cultural festival.

Jyushimatsu goes to a job interview, proving to be a total nuisance for the interviewers, while the Girlymatsu sisters try to pass the time while on vacation. Meanwhile, Chibita is asked out on a date by the fairy of a flower he saved the other day, who shows him there's more to life besides oden.

The concept of a Hijirisawa Shōnosuke-san anime quickly gets dropped due to lack of ideas, replaced with a series of skits set during the Sengoku era. Back in the present, Choromatsu decides to quit being an idol otaku and pursue a job, with Osomatsu and Todomatsu not caring much for his need to announce it. When Choromatsu's self-awareness starts to rise to annoying levels as a result, the brothers try to have him hit on girls to bring it under control, but to no avail.

Kicked out of his own company, Hatabou starts his own catering service in order to regain his fortune, leaving the Matsuno siblings curious about what meat he has been using. Later, Osomatsu and Karamatsu play as delinquent high school students competing to see who's the toughest. Afterwards, Iyami starts a comedy class hoping to earn a quick buck, only to take his teaching seriously when the siblings show up for lessons.

On a rainy evening, the brothers play a game of mahjong, with each brother showing his own strengths and glaring weaknesses. Later, the brothers suddenly find themselves joined by a seventh brother, Godmatsu, who was allegedly born from the goodness that fell out of the brothers' hearts. Although initially surprised by Godmatsu's kindness, the brothers soon become hostile when he makes their existence more pathetic in comparison to his perfectness.

Upon stopping by a pub on their way from buying some kerosene, Osomatsu, Karamatsu, and Choromatsu find themselves in an underground village populated by a tribe of Dayon people. When the others enter the village through Dayon's mouth, they find their older siblings have grown fond of the village and have started to become Dayon people themselves.

Totoko experiences jealousy for the first time after people start getting more success than her, leading her on a quest to find an oil magnate to marry.
