| 1 | Television {{Anime}} series running 10-14 episodes (generally 12). They're usually scheduled for a 3-month airing slot, if aired weekly, at OtakuOClock.[[note]]Japanese television has four general "windows" in which to premier a series, and (like most things Japanese) these windows are quite rigid. They are the first week(-ish) of January, April, July, and October; these form the "Winter", "Spring", "Summer", and "Fall" seasons respectively. So, if an anime first premiered in "Fall 2011", that means it began in October of that year. Traditionally, the Fall and Spring windows are considered more important by networks and Winter by far the least important.[[/note]] Anime with this format are commonly called '1-cour' shows, with a 24-26 episode run being called a '2-cour' show and so on; 'cour' (kuuru/クール) being a jargon term (probably from the French ''cours'') used in the Japanese broadcasting industry referring to the periods of time these shows are aired and scheduled, as detailed in the above "note". |

| 3 | This format became popular (see [[http://www.google.com/search?q=site%3Aanimenewsnetwork.com+inurl%3A%22encyclopedia%2Fanime.php%22+%22Number+of+episodes%3A+12%22 12]] and [[http://www.google.com/search?q=site%3Aanimenewsnetwork.com+inurl%3A%22encyclopedia%2Fanime.php%22+%22Number+of+episodes%3A+13%22 13]]) in the second half of the 2000s as a compromise to the often sporadic nature of {{OVA}}s and the longer, sometimes {{filler}}-ridden, previous standard of 22-26 (and even earlier, 46-54) episodes. Being a smaller time investment and financial risk, it is much easier to determine if a show will be successful; or, if it isn't, to not take on as much of a loss. In that respect, the closest Western equivalent to this trope would be Front13Back9. |
| 4 | |
| 5 | It's also common for seasons to have 13 episodes produced, broadcasting only 12 of them, and leaving the 13th as a BonusEpisode {{OVA}}. This is especially common in shows that frequently dance the line with controversial, taboo, and/or explicit {{Fanservice}} scenes. In this case, whatever the creative team wanted to do that just wouldn't bypass the MoralGuardians is saved for here. |
| 6 | |
| 7 | The only real downside to this format is the possibility of a GeckoEnding, as most anime released each season are adaptations of manga or light novels, many of which are still ongoing at the time of airing. |
| 8 | |
| 9 | Due to their length, a particularly noteworthy 12-episode anime can often lead to severe cases of AwesomenessWithdrawal. |

| 64 | * ''Manga/DeadmanWonderland'' |
| 65 | * ''Anime/DeathParade'' |

| 115 | * All four seasons of ''Manga/HidamariSketch'': the first has 12, the second has 13, the third and fourth 12 again.

| 146 | * ''Anime/TheMagnificentKotobuki'' |
| 147 | * ''Manga/{{Mahoromatic}}'' got 12; its sequel series (subtitled ''Something More Beautiful'') got 14. |
| 148 | * ''Makai Senki Franchise/{{Disgaea}}'', the [[AnimeOfTheGame anime based loosely on the game]]. |
| 149 | * ''Anime/MakuraNoDanshi'': Admittedly, they're all short, four to five minute episodes, but they do follow the twelve episode format. |
| 150 | * ''Anime/ManabiStraight'' plus an OVA, which takes place between the 6th and 7th episodes, to make this series 13 episodes when counted. |

| 160 | * ''Manga/MissKuroitsuFromTheMonsterDevelopmentDepartment'' |
| 161 | * ''Literature/{{MM}}'' |
| 162 | * ''Anime/MobileSuitGundamThe08thMSTeam'', although the twelfth episode at least feels closer to an OVA sequel episode than a series finale. |
| 163 | * ''Anime/{{Mononoke}}'' |
| 164 | * ''Manga/MonsterMusume'', plus two [=OVAs=]. |
| 165 | * ''Manga/MonthlyGirlsNozakiKun'' plus six 3-minute special episodes. |

| 170 | * ''Anime/NerimaDaikonBrothers'' |
| 171 | * ''Manga/NewGame'' |
| 172 | * ''Anime/{{Nightwalker}}'': A unique case, as the first four episodes were originally released as an OVA series. The following eight episodes were then aired as a television series. |
| 173 | * ''Manga/NinjaNonsense'' |

| 180 | * ''Anime/{{Potemayo}}'' |
| 181 | * ''Anime/PowerOfHopePrecureFullBloom'' |
| 182 | * ''Series/PowerRangersDinoForceBrave'' is a Korean rare live-action example, just like ''Akibaranger'' under the 13-Episode series. Justified since it only runs for nearly 15 minutes per episode. |
| 183 | * ''Anime/ThePriceOfSmiles'' |
| 184 | * ''Manga/PrincessPrincess'' ran for 12 episodes following three of the five volumes of manga. No word yet on whether the manga sequel, ''Princess Princess Plus'' will be getting an anime adaptation. |

| 205 | * ''VideoGame/SengokuBasara'''s first two seasons, including a pair of [=OVA=]s. |
| 206 | * ''Anime/SeraphimCall'' makes good use of this format, devoting one episode to each of its 11 central characters and having them all meet in the last one. |
| 207 | * ''Literature/{{Shimoneta}}'', plus an OVA |

| 247 | * ''Manga/YaBoyKongming'' |
| 248 | * ''Manga/YamadaKunAndTheSevenWitches''. The part of the manga it covers is 90 chapters long, leading to rather mixed reactions by those who had already read the manga. Especially the last half is noteworthily rushed, while the first half is more faithful to the manga. |

| 268 | * ''Manga/JyuOhSei'' |
| 269 | * ''Literature/{{Kampfer}}'' is an odd case; it's 12 episodes, but it's basically an 11-episode series with episode 12 being a fanservicey, non-continuity {{bonus episode}} that's aired after the ending [[GeckoEnding such as it is]]. |

| 323 | * ''Anime/BottleFairy'' |
| 324 | * ''Anime/BuddyComplex'' |

| 326 | * ''Anime/{{Canaan}}'' |
| 327 | * ''Anime/CarriedByTheWindTsukikageRan'' |
| 328 | * The Monkey Punch anime ''Anime/CinderellaBoy''. The series ended [[spoiler: whilst Ranma/Rella's daily FreakyFridayFlip still wasn't resolved]] and originally suggested an upcoming new season. Unfortunately, the high cost caused the series to be put to a premature end. |
| 329 | * ''Anime/DanganronpaTheAnimation'' |
| 330 | * ''Anime/DayBreakIllusion'': Plus an unaired 14th episode that serves as a prequel. |
| 331 | * ''Manga/DescendantsOfDarkness'' |
| 332 | * The original series ''Literature/DeepLove'' was thirteen episodes, while the spin-off ''Deep Love ~Host~'' ran for twelve. |

| 336 | * ''Anime/EarthMaidenArjuna'' |
| 337 | * ''Manga/ElfenLied'' is a ThirteenEpisodeAnime, plus [[BonusEpisode the 14th DVD-only episode]]. |
| 338 | * ''Anime/EngageKiss'' |
| 339 | * ''Anime/Figure17TsubasaAndHikaru'' has 13 episodes, but is somewhat unique in that each episode is 45 minutes long, and one episode was shown each month during its first airing. As such, the anime takes significantly more time exploring and developing its characters, has a gentler pace, and animation and art that's practically OVA quality. |
| 340 | ** It was later rebroadcast as a standard 26 episode show, with each episode cut in half. |
| 341 | * ''Anime/{{Flag}}'' |
| 342 | * ''[[Literature/FullMetalPanic Full Metal Panic! The Second Raid]]'' had 13 episodes, with a separate 30 minute {{OAV}} produced afterwards. |

| 344 | * ''Anime/{{Glasslip}}'' |
| 345 | * ''Anime/GRGiantRobo'' |
| 346 | * ''Manga/{{Gravitation}}'', cut so heavily it would need a sequel series to bridge the gap to the manga's sequel series. |
| 347 | * ''Manga/GunslingerGirl'', with 13 episodes and a 13-episode sequel, as well as a 2-episode OVA. |
| 348 | * ''Manga/HappyHappyClover'' had a total of 13 episodes made in 2007 which adapted the first three volumes. |

| 350 | * ''Manga/{{Hanebad}}'' |
| 351 | * ''Anime/{{Hellsing}}'' got 13 episodes. All funding was cut around episode 10-11, and they had just enough to wrap up the series in the next two-three episodes. |
| 352 | * ''Literature/{{Higehiro}}'' |
| 353 | * ''Series/HikoninSentaiAkibaranger'' is a rare live action example. Interestingly, it was originally supposed to be a one season show with twelve episodes, but the budget increased for one more episode. Then, a second season was made that also lasted thirteen episodes. |
| 354 | * ''Manga/{{Hyakko}}'' has 13 episodes and a short 12-minute-long OVA. |

| 361 | * ''Manga/KannagiCrazyShrineMaidens'' |
| 362 | * The first ''VisualNovel/{{Kanon}}'' TV adaptation is 13 episodes long plus a special. The [[Creator/KyotoAnimation KyoAni]] remake was a full season with 24 episodes. |
| 363 | * ''Anime/KeyTheMetalIdol'' -- though it came out as a total of 15 episodes: 13 regular, plus two "movies". |
| 364 | * ''Literature/KinosJourney'' is another 13-episode series. |
| 365 | * ''Manga/KoiKaze'', although episode 8 was unaired on tv. It was included on the dvd box though. |
| 366 | * ''Manga/KokoroLibrary'' |
| 367 | * ''Legends Of The Dark Kings'' (aka ''Ten no Haoh''), a 13-episode anime adaptation of a manga spinoff of ''Manga/FistOfTheNorthStar'' that centers around [[BigBad Raoh]]. |

| 370 | * ''Anime/LycorisRecoil'' |
| 371 | * ''Anime/MagicalGirlLyricalNanoha'' and its sequel series ''Anime/MagicalGirlLyricalNanohaAs'' compacted 26 episodes of plot into 13 high-pressure episodes; however, ''Anime/MagicalGirlLyricalNanohaStrikers'' was the standard length (and pace) of a 26 episode series. |

| 373 | * ''Anime/MegaloBox'' |
| 374 | * ''Anime/MetalFighterMiku'' |
| 375 | * ''Anime/MezzoDSA'' |
| 376 | * ''Manga/MidoriDays'' got 13 episodes (which is probably why two major characters from the manga, Lucy and Nao, were left out). |
| 377 | * ''Literature/TheMisfitOfDemonKingAcademy'' |
| 378 | * ''Anime/MobileSuitGundam0083StardustMemory'' |
| 379 | * ''[[Literature/MyYouthRomanticComedyIsWrongAsIExpected My Teen Romantic Comedy SNAFU]]'', the first and second seasons have 13 episodes each, but the third has only 12. All 3 seasons also have one OVA episode each. |
| 380 | * ''Anime/MyselfYourself'' |

| 386 | * ''Anime/OkusamaWaMahouShoujo'' |

| 398 | * ''Anime/SerialExperimentsLain'', true to its indie nature, is a thirteen-episode series. |
| 399 | * ''Manga/ServantXService'' |
| 400 | * ''Manga/ShadowStar'' got 13 episodes. |
| 401 | * ''Anime/{{Shenmue}}'' |
| 402 | * ''Animation/StitchAndAi'' is a Chinese variant of this trope. Only one thirteen-episode season was produced and released, which aired with a Mandarin Chinese dub (the show was originally produced in English with American animators assisting) from March 27 to April 6, 2017. The original English version aired in Southeast Asia throughout the month of February 2018. It later received a free digital streaming release in the United States on December 1, 2018, albeit with the show's ninth episode remaining unreleased there. |
| 403 | * ''Manga/SubmarineSuper99'' |
| 404 | * ''Manga/ShouwaGenrokuRakugoShinjuu'', with the first being a retelling of the [=OVAs=]. The [=OVAs=] cover the first volume. The anime's two seasons cover all 10 volumes of the manga. |
| 405 | * ''WesternAnimation/TheSilverBrumby'''s [[ShortRunner only season]] had 13 episodes. |
| 406 | * ''Anime/SpacePatrolLuluco'': Ran for 13 episodes during the Spring 2016 season, which were idiosyncratically divided into four "seasons" of three episodes each, plus "season final" consisting of just the 13th episode. |
| 407 | * ''Literature/SpiceAndWolf'' had [[BonusEpisode 13 episodes]], with the 7th episode being DVD-only. The second season had 12 episodes, with an epilogue to the last season as an [[BonusEpisode episode 0]] on DVD. |

| 409 | * ''Anime/StrainStrategicArmoredInfantry'' |

| 411 | * ''VisualNovel/ToHeart'' |
| 412 | ** ''VisualNovel/ToHeart2'' as well, however, it has a three part OVA, and a two part OVA spinoff ''To Heart 2: Another Days'', which is loosely based on the GaidenGame spinoff of the same title. |
| 413 | * ''Manga/{{Tokko}}'' |
| 414 | * ''Manga/TonaGura'' has 13 episodes with a semi-firm conclusion. That said, the manga is still ongoing, and whether or not this conclusion is used remains up in the air. Up until 2009, manga chapters tended to be fully fleshed, expanded versions of the anime episodes. |
| 415 | * ''Literature/{{Tsurune}}'', plus one OVA. |
| 416 | * ''Literature/VioletEvergarden'', plus one OVA and two movies. |
| 417 | * ''Manga/{{Wagnaria}}'' |
| 418 | * ''Manga/WhisperedWords'' |
| 419 | * ''Anime/WindyTales'' |
| 420 | [[/folder]] |
| 421 | |
| 422 | [[folder:Originally This, But Given More Seasons]] |
| 423 | * ''Literature/AscendanceOfABookworm'' started with a 14-episode season, then got a two-part OVA followed by a second season of 12 episodes, another two-part recap, and then a third season of just 10 episodes. |
| 424 | * ''Manga/{{Beastars}}'' got 12 episodes for its first season, and then it received another 12 for its second season. |
| 425 | * ''Manga/BirdyTheMighty Decode'' got 13 episodes; its second season got 12 (but with bonus episode #13 produced shortly after... which technically acts as original episode 1). |
| 426 | * ''Literature/CoffinPrincessChaika'': 12 episodes for season 1, 10 for season 2. |
| 427 | * ''Literature/DateALive'' has, as of 2022, run for four seasons, all of which are 12 episodes each save the second season, which was 10, and with a fifth confirmed. |
| 428 | * ''Manga/DontToyWithMeMissNagatoro'' has two seasons of 12 episodes each, the first starting in April 2021 and the second in January 2023. |
| 429 | * ''Manga/DropkickOnMyDevil'' was intended to only have one season, due to little-to-no interest or fanfare to justify continuing it to adapt the rest of the manga. It wasn't until its home media sales, and later crowdfunding, that granted it more seasons. |
| 430 | * ''Literature/TheFamiliarOfZero'' started with 13 episodes, and has three sequel seasons with 12 each. |
| 431 | * ''Anime/{{Gravion}}'' had 13 episodes with little to no conclusion. All of them are wrapped up nicely in the 12 episodes sequel ''Gravion Zwei''. There were plans for a 3rd season, but since most plot elements have been concluded, they decided to turn it into ''Anime/DancougarNova'' instead. |
| 432 | * ''Literature/{{Haganai}}'' started with 12 episodes in fall 2011, then got another 12-episode season in winter 2013. |
| 433 | * ''Manga/ICantUnderstandWhatMyHusbandIsSaying'' and it even [[LampshadeHanging lampshades]] how most anime only run for 12/13 episodes and Hajime admits he's always curious on how it goes on with the heroes after, during its own 13th episode. Then [[http://www.animenewsnetwork.com/news/2014-12-25/i-cant-understand-what-my-husband-is-saying-anime-gets-2nd-season/.82612 the anime got a second season]] right after this episode. |
| 434 | * ''Literature/IsThisAZombie'' had 12 episodes in its first season, but its second season had only 10 episodes. |
| 435 | * ''Manga/{{Ikkitousen}}'''s first season had 13 episodes. It later got another three seasons of 12 episodes each. |
| 436 | * ''Literature/InfiniteStratos'' has two 12-episode seasons, not counting the OVA. |
| 437 | * ''Manga/KaguyaSamaLoveIsWar'' ran for three seasons, the first two for 12 episodes each and the third for 13 episodes, including an OVA between the second and third. |
| 438 | * ''Anime/KoihimeMusou''. All 3 seasons have 12 episodes. |
| 439 | * ''Literature/LoveChunibyoAndOtherDelusions''. Both seasons contain 12 episodes plus an {{OVA}}. Given their plot importance, they could be seen as 13-ep seasons.[[note]]This also doesn't include the six per season ''Lite'' episodes which together equal another complete episode.[[/note]] |
| 440 | * ''Literature/MariaWatchesOverUs'' has three 13-episode seasons. |
| 441 | * ''Manga/MissKobayashisDragonMaid'' had 13 episodes plus an OVA and 7 DVD mini-episodes, then got a second season of 12 episodes plus another OVA. |
| 442 | * ''Webcomic/MobPsycho100'' started with a 12-episode first season, then got a second season of 13 (with an additonal OVA ChristmasEpisode). Eventually, it also had a third season which has 12 episodes like the first season. |
| 443 | * The first season of ''Manga/MyHeroAcademia'' was 13 episodes, but every subsequent season has had 25 each. |
| 444 | * ''Manga/NonNonBiyori'' has three seasons of 12 episodes each, plus several [=OVAs=] and TheMovie. |
| 445 | * ''Webcomic/OnePunchMan'' had 12 full episodes, with a few [=OVAs=] aired after the end of the season. Later the series got 2nd season, with the same number of episodes and six special episodes again. |
| 446 | * ''Literature/{{Oreimo}}'' has twelve broadcast episodes in its first season and 13 in its second, plus four {{OVA}} episodes. |
| 447 | * ''Manga/ThePromisedNeverland'' ran for 12 episodes, then got a second season of 11 which was considered to be rushed, leaving out several arcs from the manga. |
| 448 | * ''Anime/SailorMoonCrystal'' has ran for three 13-episode seasons, each adapting an arc from the [[Manga/SailorMoon manga]]. The remaining two arcs were adapted via movies. |
| 449 | * All three ''Manga/SayonaraZetsubouSensei'' seasons are 12-13 episodes long. |
| 450 | * ''Manga/StrawberryMarshmallow''. Two OVA series, one with three episodes, the other with two, were made after the TV series, so there are now 17 episodes of Ichigo Mashimaro. |
| 451 | * ''Anime/{{Symphogear}}'': originally a one-shot 13-episode series, it was eventually expanded to '''five''' 13-episode seasons mostly on the back on music sales. |
| 452 | * ''Manga/TeasingMasterTakagiSan'' had three 12-episode seasons, [[BonusEpisode a Season 1 OVA]], [[TheMovie and a movie]]. |
| 453 | * ''Literature/TheTestamentOfSisterNewDevil'': Two seasons, the first being 12 episodes and the second being 10, along with three [=OVAs=] (one each at the end of each season, then a third standalone after season 2). |
| 454 | * ''Manga/UzakiChanWantsToHangOut'' has two 12-episode seasons so far. |
| 455 | * ''Anime/{{Vandread}}'' first aired with 13 episodes, but managed to get a second 13 episodes and resolve the story. There's rumors of a third season, but aren't there always? |
| 456 | * ''VisualNovel/WhiteAlbum'' was 13 episodes, then got a sequel, ''VisualNovel/WhiteAlbum2'', which is also 13 episodes. |
| 457 | * ''Anime/ZombieLandSaga'' originally aired with only 12 episodes, but due to the massive popularity in Japan alongside the show's critical acclaim, a second season was announced in 2019, under a new title: ''Zombie Land Saga: Revenge''. |
| 458 | [[/folder]] |
| 459 | |
| 460 | [[folder:Unusual Cases]] |
| 461 | * ''VideoGame/AngelsOfDeath'''s anime adaptation is 16 episodes long. |
| 462 | * ''Manga/{{ARIA}}'' The ANIMATION and The ORIGINATION (Season One and Season Three) are both 13 episodes in length whereas ARIA The NATURAL (Season Two) is 26 episodes long. |
| 463 | * ''Manga/AttackOnTitan'': Its first season was 25 episodes long, then its second season was 12. The third season is quite unusual: it was 22 episodes in total, but it was split up six months apart into a Part One and Part Two consisting of 12 and 10 episodes, respectively. The fourth and final season was likewise 35 episodes, split into two halves aired a year apart with respectively 16 and 12 episodes, followed by a pair of specials that were themselves further split into another 7 episodes, 3 for the first one and 4 for the second. |
| 464 | * ''Anime/AyakashiSamuraiHorrorTales'' was aired as an 11-episode series on Japanese television, but is actually an anthology consisting of [[TelevisionSerial three separate 3- or 4-episode anime]] by completely different production groups. The final series in the anthology, "Bakeneko", ended up with its own spinoff, ''Mononoke'', also a 12-ep series. |
| 465 | * ''Manga/AzurLaneSlowAhead''[='=]s anime adaptation is twelve episodes long (plus a home release-exclusive OVA) just like its more serious counterpart, though they're each only eight minutes. |
| 466 | * ''Literature/{{Bakemonogatari}}'' ran for 15 episodes. |
| 467 | ** ''Nisemonogatari'': 11 episodes |
| 468 | ** ''Monogatari Series: Second Season'': 26 episodes |
| 469 | ** ''Owarimonogatari'': 12 episodes |
| 470 | * While ''Literature/BeyondTheBoundary'' only has one 12-episode season in 2013 with a prequel OVA, it later received two movies, the first one airing in 2014, adapting the anime series; the second one served as a sequel, which aired in 2015. It also had several spinoff shorts. |
| 471 | ** ''Anime/BlueLiterature'' follows the same format, with five arcs adapted from Japanese literature. |
| 472 | * ''Anime/TheBigO'', though notable for being one of the first shows of this type to get a second season, was actually planned as a 26-episode anime, but had production end after only 13 due to low ratings in Japan - the second season, co-produced by Creator/CartoonNetwork after [[GermansLoveDavidHasselhoff the show pulled much better ratings abroad]], was essentially just bringing the staff back to finish the other half of the original series. |
| 473 | * ''Manga/BlackButler'' started off by having a 24 episodes in its first season (plus one OVA). Its second season had only 12 episodes (with an additional 6 [=OVAs=]). Later on, its third season, ''Book of Circus'' (which unlike its notorious predecessor, is more faithful to the manga), only had 10. In addition, there were also and additional two, hour-long [=OVAs=] and a movie which continue on from the third season. |
| 474 | * ''Anime/BlackRockShooter'' is eight episodes long, and was aired in Creator/{{noitaminA}}. If you count the OVA (which was released two years earlier and is in a separate continuity), then it had nine episodes in total. |
| 475 | * The 2019 adaptation of the ''Literature/BoogiepopSeries'' was 18 episodes long. The series started off with a one-hour special with the first two episodes debuting immediately, and then in a truly unique situation, episodes 10-13 were all released at once when the show hit that point, leaving enough time for the entire season to finish its run in a standard season. |
| 476 | * ''Anime/BuddyComplex'' had a first season with 13 episodes. It was slated for a second season, but low ratings caused season 2 to get cut to only ''two episodes'' which released as a pair of [=OVAs=]. |
| 477 | * ''Manga/CellsAtWork'', had 13 episodes in its first season (the same can be said with its spinoff, ''BLACK''). However, the second season had a mere run of only 8 episodes. |
| 478 | * ''Manga/DGrayMan'' in its first TV broadcast from Oct. 2006 to Sept. 2008 had a whopping 103 episodes. The odd thing is that the show is considered to be 2 seasons of 51 and 52 episodes, even though there was no break in the airing schedule and it continuously aired until the end. Regardless, the manga went on hiatus for over 2.5 years before returning in July 2015. A continuation series called ''D. Gray Man: Hallow'' aired starting July 2016 and picked up where the first anime left off, but ''Hallow'' was only 13 episodes long. |
| 479 | * ''Manga/DemonSlayerKimetsuNoYaiba'' got 26 episodes for its first season, but after that it gets unusual: officially, the second season is 18 episodes, but it is split between the two arcs it adapts, "Mugen Train" getting a film that was later split into 7 episodes and "Red-Light District" taking up the next 11. The season after that adapts the "Swordsmith Village" arc, once again with 11 episodes. |
| 480 | * ''Anime/DigimonAdventure'' was written so that it could end cleanly after 13 episodes. It didn't have to, and ultimately ran to 54 episodes, and eight more seasons followed after that. |
| 481 | * The first arc of ''Manga/DragonBall'' had its 23 chapters into 13 episodes, with some chapters being expanded to fill an entire episode while several others were consolidated into one. Presumably this was done to fit this trope on the off-chance that the anime didn't catch on. [[Anime/DragonBallZ Needless]] to [[Anime/DragonBallGT say]], it [[Anime/DragonBallSuper did]]. |
| 482 | * ''Manga/DrStone''[='=]s first season has 24 episodes, with the second season having 11 episodes. It also got a spin-off movie, ''Dr. Stone: Ryusui'', lasting 54 minutes. |
| 483 | * ''Literature/{{Durarara}}'' in its initial run had 24 episodes, divided into two halves and denoted by the different opening and closing credits sequences. For its second run, it had 36 episodes which were divided into three cours. Unlike the first run where both cours were broadcast back-to-back, the new cours were released separately - ''Shou'' was in Winter 2015, ''Ten'' was in Summer 2015, ''Ketsu'' was in Winter 2016. |
| 484 | * ''Literature/FateZero'''s first season has 13 episodes, but it's effectively 14 episodes, because the first episode is 45 minutes long. This was apparently done to get the [[InfoDump humongous amount of prologue exposition]] (for a show which is ''itself'' a prologue for [[VisualNovel/FateStayNight an entire franchise]]) out of the way in the first episode. The second season is a normal 12-episode season. |
| 485 | ** ufotable's next ''Fate'' adaptation, ''Anime/FateStayNightUnlimitedBladeWorks'', is an even crazier case. The first season is 12 episodes, but it's actually ''16'' episodes long because there was a prologue "Episode 0" that was 45 minutes long, and Episodes 1 and 12 were '''also''' double-length episodes. The second season was 13 episodes, all standard length this time. |
| 486 | * ''Manga/FateKaleidLinerPrismaIllya'', a spinoff series of the above-mentioned ''Fate'' franchise, started its anime adaptation with a 10 episode season. Then the second season got split into two cours, each one 10 episodes long. The third season is 12 episodes long. |
| 487 | * ''Anime/Figure17'' is a particularly odd example. 13 episodes long, pretty standard. Only the episodes are 40 minutes long and even stranger still, released over a period of almost exactly one year. And it's not a case that they had a break half way through, no, they aired each individual episode almost one month apart. |
| 488 | * The first season of ''Manga/FoodWars'' was 24 episodes long. The second season, ''Ni no Sara'', was only 13 episodes long, much to the fanbase's irritation because the manga has plenty more content that could easily be adapted. The third season, ''San no Sara'', went back to 24 episodes, but it was a split-cour season divided into two 12-episode airings in Fall 2017 and Spring 2018. The fourth season, ''Shin no Sara'', was 12 episodes in Fall 2019. The fifth and final season, ''Gou no Sara'', was 13 episodes in Summer 2020. |
| 489 | * ''VideoGame/GirlsFrontline''[='=]s "Healing Chapter" (which tells original stories) and "Madness Chapter" (which adapts {{yonkoma}} chapters from the game's loading screens and the comics purchased with in-game currency) are 12 episodes each, though the episodes are only three minutes long. The former later got a second season with six-minute-long episodes, followed by [[Anime/GirlsFrontline a proper anime of its manga adaptation]], also with 12 standard-length episodes. |
| 490 | * ''Manga/{{Haikyuu}}'''s first two seasons were 25 episodes long each, along with a 2 episode OVA. The third season is only 10 episodes long. Later on, the fourth season was released as separate two cours with the first cour airing with 13 episodes and the second cour only having 12. |
| 491 | * The initial run of ''[[Literature/HaruhiSuzumiya The Melancholy Of Haruhi Suzumiya]]'' got 14. The second season also has 14 episodes for a total run of 28. |
| 492 | ** One of the first season's episodes is the NonIndicativeFirstEpisode, which is a "movie" created by the SOS club rather than a normal episode. |
| 493 | ** Also consider that 8 of 14 episodes in season two [[GroundhogDayLoop are generally the same]]. |
| 494 | * The anime adaptation of ''VideoGame/IDOLiSH7'' has 17 episodes in the first season, 15 episodes in the second and 30 episodes (split into two blocks of 13 and 17) in the third. |
| 495 | * ''Manga/JoJosBizarreAdventure'': |
| 496 | ** The first season was a standard 26 episodes, but adapted two arcs at once, ''[[Manga/JojosBizarreAdventurePhantomBlood Phantom Blood]]'' taking 9 episodes and ''[[Manga/JoJosBizarreAdventureBattleTendency Battle Tendency]]'' taking 17. |
| 497 | ** ''[[Manga/JojosBizarreAdventureStoneOcean Stone Ocean]]''[='=]s season was 38 episodes, only one less than those for ''[[Manga/JoJosBizarreAdventureDiamondIsUnbreakable Diamond is Unbreakable]]'' and ''[[Manga/JoJosBizarreAdventureGoldenWind Golden Wind]]'', but its release schedule was in three sets: the first 12 on December 1st 2021, the next 12 on September 1st 2022, and the last 14 on December 1st 2022. |
| 498 | * ''Anime/{{Kamichu}}'' had 12 to start, with four DVD-only episodes interspersed between the broadcast episodes. A ploy to get people to buy the [=DVDs=], as the DVD-only episodes are ''not'' strictly filler. |
| 499 | * ''Manga/KOn'''s first two arcs are only twelve episodes, but the show ended with a special episode outside of the second arc. Then it skyrocketed in popularity, and the second season got 26 episodes. |
| 500 | * ''Literature/KokoroConnect'' has 13 episodes, but with 4 [=OVAs=] concluding the story in 2013, making 17 episodes altogether. |
| 501 | * ''VisualNovel/LittleBusters'' had a 26-episode first season covering Komari, Mio, Haruka, and Kud's routes along with most of the common route, and then a 13-episode second season covering Kurugaya's route, Rin's route, and Refrain. |
| 502 | * ''Anime/MagicalPokaan'' ran for 12 episodes, albeit in [[ThreeShorts Two-Shorts format]], and with the DVD releases added three more OVA episodes. |
| 503 | * ''Anime/PokemonJourneysTheSeries'' lasted for 136 episodes, which is standard for [[LongRunners an individual iteration of the Pokémon anime]]. However, once it was decided to retire Ash Ketchum and the Team Rocket Trio from the franchise, [[PostScriptSeason an additional twelve episodes were allotted]] to wrap up their character arcs before [[Anime/PokemonHorizonsTheSeries moving onto the next iteration]]. These twelve episodes were released under the banner of ''Anime/PokemonToBeAPokemonMaster''. |
| 504 | * ''Anime/PrincessTutu'' was a VERY odd variation on this in its original TV broadcast. The first 13 episodes of the series were the standard 30 minutes each, but a time-slot change beginning with episode 14 lead to the running time being halved and the latter half of the series airing as 24 episodes of 15 minutes each - until the final episode, which was again 30 minutes long. Even more strange is that there was no gap in airing between the "seasons" - the 15-minute episode 14 aired the week after the full-length 13. Confused yet? The DVD release restored the split episodes into 30-minute ones, making it look like a 26-episode series to those who don't know its broadcast history. Of course, there were also the three TV specials produced. |
| 505 | * ''Anime/PsychoPass'', as far as its regular TV broadcasts went, started off with a 22-episode first season. The second season was 11 episodes long. The third season was only ''8'' episodes, but in a rather unique case, each episode was double-length (45 minutes long), effectively making it the equivalent of a 16-episode season. Season 3 then had the sequel movie ''Anime/PsychoPass3FirstInspector'' as its conclusion, which was over 2 and a quarter hours long, which essentially made Season 3 have a runtime equivalent to 22 episodes, the same as the first season. |
| 506 | * ''Manga/ShrineOfTheMorningMist'' has 26 episodes, but each is under a quarter of an hour long, half the "standard" episode length. |
| 507 | ** The same goes for the ''Anime/GalaxyAngel'' anime. |
| 508 | ** And ''Manga/SteelAngelKurumi'' |
| 509 | ** Same goes for ''Manga/CromartieHighSchool'', though they generally broadcast them in pairs. |
| 510 | ** As well as ''Manga/RiskySafety'', but it has 24 episodes. |
| 511 | ** ''VisualNovel/WWish'' and ''VisualNovel/FinalApproach'' each have 13 twelve-minute episodes, aired side-by-side during the "Princess Hour." |
| 512 | * The fourth season of ''Literature/{{Slayers}}'' ending up being split into two 13-episode seasons instead of one 26-episode season. Of course, Revolution leaves a lot of plot threads for Evolution-R to pick up, but season five did get a new OP and ED... |
| 513 | ** This isn't too dissimilar to how previous series of Slayers played out: typically, TheDragon would be fought by Episode 13, and from episode 14 onwards, the focus would shift to TheManBehindTheMan or some other BigBad therein. |
| 514 | ** It has, however, been packaged together in Japan and elsewhere. |
| 515 | * ''Anime/SpaceDandy'' consists of two 13-episode seasons, although this had been planned out before it began airing, so it can also be considered a 26 episode series with a break in the middle. Nonetheless, it's still officially two seasons. |
| 516 | * ''Manga/SpyXFamily''[='=]s first season is 25 episodes but aired in two parts across 2022, 12 episodes from April to June and the next 13 from October to December. |
| 517 | * ''Series/TokusatsuGaGaGa'' only ran for seven episodes. |
| 518 | * ''Manga/TokyoRevengers''[='=] second and third seasons are 13 episodes, following on from a first season of a more standard 24. Some sources also refer to the second and third seasons as one individual season of 26 episodes that aired in two parts six months apart. |
| 519 | * The second season of ''Anime/YukiYunaIsAHero'' is broken down into two six-episode series, ''[[Literature/WashioSumiIsAHero Washio Sumi Chapter]]'' (which was originally three theatrical films) and ''Hero Chapter''. |
| 520 | * ''Manga/TheWayOfTheHousehusband'' was released with 5 episodes (though some fans would hesitate to call it "[[LimitedAnimation anime]]"), and an unknown number of future episodes have been planned. |
| 521 | * ''Anime/{{Yasuke}}'' has 6 episodes, though there are rumors of a planned second season. |
