History Anime / OsomatsuSan

* TheyreNotRealReveal: The Season 2 episode "Imaginary Friend" focuses on the Matsuno brothers recalling when they all had imaginary friends in high school. Meanwhile, Choromatsu Matsuno reunites with his high school friend and both go on a subplot together. At the end of the episode, the audience learns that ''even the school buddy'' was an imaginary friend, as no one but Choromatsu could see and interact with him.

* WidgetSeries: Though ''Manga/OsomatsuKun'' wasn't without its own surreal humor, this series takes it up a notch.

A third season was announced in 2020 and premiered on October 12th, 2020.

** The ending theme has Iyami mention that he should be the main character of the anime because he's obviously the best of the cast. Pierrot actually did this with the 1988 ''Osomatsu-kun'' anime, with Iyami indeed as the main character alongside Chibita. The idea gets brought up a couple more times in the show.

** In "Accident?", Osomatsu walks in on Choromatsu at a [[ADateWithRosiePalms less than stellar time]], which makes him angry and bitter for the rest of the day and eventually escalates to an all out brawl with all of the brothers participating.

* OneMillionBC: The "Cavematsu-san" shorts take place in this setting.

** "Totoko's Huge Panic" deals with Totoko's fears of being considered inadequate by others and becoming a ChristmasCake. She then develops a desire to get married, specifically to an ArabOilSheikh.

The series premiered in the fall of 2015. Crunchyroll licensed the anime for streaming under the title ''Mr. Osomatsu''. At first, the series was [[https://www.animenewsnetwork.com/news/2015-11-09/mr-osomatsu-anime-to-run-for-2-consecutive-seasons/.95187 announced]] to be a two cour anime, with the second half beginning in the Winter2016Anime season, but this was eventually [[http://www.animenewsnetwork.com/news/2016-01-31/mr-osomatsu-planner-we-havent-said-it-will-end-after-half-a-year/.98174 rebutted]] once the series became a [[SleeperHit surprise success]] in Japan, and [[http://www.animenewsnetwork.com/news/2017-04-06/mr-osomatsu-tv-anime-gets-2nd-season/.114447 a second season was eventually greenlit]], which had been scheduled for a October 2017 premiere. Creator/VizMedia announced the US license to both seasons in August 2017 with an English voice track included in home video releases due for March 2021. A Latin American Spanish dub was announced as well, making the first time anything related to ''Osomatsu-kun'' came out in that region, as it only was released in Spanish in Spain exclusively.

The series aired as part of the Fall2015Anime season. Crunchyroll licensed the anime for streaming under the title ''Mr. Osomatsu''.

** Parodied in the first half of the [=DVD=] exclusive episode, which consists of nothing but a montage of the brothers' [[SexierAlterEgo F6 forms]] doing sexy things in cool outfits while saying cliched lines. As the segment goes on, the outfits and scenarios, which start out fairly standard (Choromatsu as a HotScientist, Todomatsu as a sensitive artist, Karamatsu as a cool biker, and so on) become increasingly more surreal and harder to follow (such as Osomatsu as a tenko drummer, Karamatsu emerging from the bathroom, and Jyushimatsu battling a wild horse while wearing nothing in but a fundoshi), but the brothers continue to act as though what they're doing is cool and sexy.

* WeaponOfChoice: The brothers start brandishing these while plotting to kill Godmatsu. Osomatsu has [[ShearMenace garden shears]], Todomatsu has a [[SinisterScythe scythe]], Karamatsu has a [[GatlingGood minigun]], Ichimatsu has [[SuicideAttack dynamite]], and Jyushimatsu has [[BatterUp a baseball bat with nails in it]].

* WereStillRelevantDammit: {{Invoked}} by Osomatsu. The entire premise of the first episode was the cast trying to pass themselves off as marketable to modern (mid 2010s) audiences.

** "''Osomatsu-san'' Returns!" focuses on the "proper" way to reboot a series, as told through the '66 sextuplets hating how crass and selfish their ''-San'' counterparts are and resolving to find a better way. Despite their ideas (a lowkey TimeSkip, a {{Retraux}} throwback, all the way up to a live-action adaptation), none of them can come to an agreement.
** "Untitled" begins with an announcement that the cast is being changed into less controversial versions of themselves, shown through putting the sextuplets through {{Gender Flip}},s, {{Race Lift}}s, and personality swaps to see if the results are more likeable.

* RebootSnark: Each season starts with the series getting rebooted, with the cast coming up with so many ideas for how to run it [[TooManyCooksSpoilTheSoup the resulting show is unrecognizable]]. Eventually, they give up and the show proceeds as normal.
** Season 1 focuses on the ''Manga/OsomatsuKun'' cast as they appear in the 1966 adaptation trying their hand at rebooting it, worried their humor will come off as dated. They cram in as many early 2010s anime trends as they can think of, but the pressure of maintaining it all causes the scenario to fall apart.
** Season 2 has the '66 sextuplets become so disgusted at their reboot selves that they study different media and genres to do a "proper" revival. When they meet up again, the brothers, now stylized to fit their chosen medium, clash over which direction to take the series.
** Season 3 has the sextuplets go through different reboots to see what the audience would find the least controversial.

*** Taken UpToEleven in Season 3 Episode 2, where he expresses doubt in relying on AI when he is addicted to a Nyaa-chan themed VR dating game just moments before (complete with [[CovertPervert suggestive postures]]). Osomatsu is so disgusted that he promptly produces a VR device and puts it on Choro, causing him to get high instantly and look like a fool in front of his brothers, but once the device is removed, Choro takes no time to resume his StraightMan persona. Osomatsu grudgingly expresses astonishment.

** Turned UpToEleven during "Hijirisawa Shonosuke-san", where the main cast is a group of ''heptadecuplets''.

* WidgetSeries: Though ''Manga/OsomatsuKun'' wasn't without its own surreal humor, this series takes it UpToEleven.

** While neither of the two can compete with Totty in the dialogue department, Jyushimatsu and Ichimatsu get quite a significant amount of focus as well. Jyushimatsu, as mentioned in ADayInTheLimelight, had a whole half hour devoted to skits about him, and Ichimatsu gets a lot of fleshing out in both the first and second cour.

* DerailedFairyTale: One skit has a scene focusing on a retelling of ''Literature/TheTortoiseAndTheHare'', but continues after the tortoise gets to the finish line. Instead of the story ending on the usual cliche of the Hare ultimately getting the better of the tortoise after they stop sleeping, the story continues from ''there'' and shows that the race is never ending and that for every win the Hare gets, there will always be someone [[AlwaysABiggerFish better than somebody else, including him]], no matter how talented they are or how hard they work. Meanwhile, the tortoise gives up on life and slowly sinks into [=NEETdom=] while ruining his family life and getting into hedonistic pleasures.

* StatusQuoIsGod: The show beats the characters over the head with this and then some. Anyone who gets a job is doomed to lose it come the next skit. Anyone who gains a love interest can't keep them come the end of the episode, for [[BastardGirlfriend better]] or for [[DidNotGetTheGirl worse]]. If they've killed each other or someone else, destroyed the city, or made some seriously stupid mistakes, [[ResetButton it's all good]]. Even when the worst has happened, and the boys are all split from each other with no bright moment in sight for that episode, that's perfectly a-okay because [[spoiler: they'd give it all up anyway to play baseball.]] At least part of it's justified on the sextuplets' side: see TallPoppySyndrome.

* AdultFear:
** Ichimatsu exploits this when he's given a chance to keep being dependent on his parents. He appeals to his mother's fears of her children not being able to handle the outside world, and asks what she would do if he stopped taking care of himself and fell into criminal activity after he left home.
** For all of the Matsunos, and ''especially'' Osomatsu, [[TheFellowshipHasEnded growing up and leaving each other]].

* SomethingCompletelyDifferent:
** "Sanematsu-san" completely takes the focus away from the cast of the show to instead focus on a pitiful {{salaryman}} named Sanematsu as he goes through a day of work. The entire thing is done in the style of a subdued, adult live-action drama rather than a gag anime, meaning there's little to no intentional comedy. [[spoiler: Though, the reveal that he's delusional was a bit of a surprise.]]
** "[[ExactlyWhatItSaysOnTheTin Real Life Matsus]]" takes the setting completely away from the [=2D=] plane, and follows a group of actors with paper masks of the Matsuno brothers walking around Chiba. It's also a no-dialogue skit.

* DiabolusExMachina Both season finales have elements of this:
