[[caption-width-right:350:''Ouen! Dai seikou!'']]

From [=iNiS=], the creators of ''VideoGame/GitarooMan'', comes this rather clever RhythmGame for the Nintendo DS. ''Osu! Tatakae! Ouendan'' ("Yo! Fight! Cheer Squad") revolves around a group of male cheerleaders who go around rooting on people all across Tokyo in a variety of tasks to a variety of Japanese pop and rock music. Their clients include Tsuyoshi Hanada, a ''ronin'' student trying to get into Tokyo University; Yasushi Tanaka, owner of a ramen shop trying to drum up more business; and Ichiro Tamura, a {{Salaryman}} who... grows to fifty feet tall in order to save his daughter (and the city) from [[AttackOfThe50FootWhatever a giant blue mouse on the rampage]].

[[OneOfTheseThingsIsNotLikeTheOthers Then there's the stage where they get pulled through time and space to cheer on Cleopatra's royal construction crew so she can lose weight via pyramid power...]]

And for the GrandFinale, they cheer on the whole world to create a CombinedEnergyAttack big enough to save the planet from impact with a giant asteroid.

It's a weird game, but that's [[WidgetSeries part of the appeal]] -- it seemingly crams as many familiar anime, manga and UsefulNotes/JapaneseCulture tropes in as it can to make it as Japanese as possible. The game mechanics make good use of the DS stylus, as they involve tapping markers that appear on the screen in time to the music.

The original game was a [[GermansLoveDavidHasselhoff hit]] with {{import gam|ing}}ers. It was such a hit, in fact, that it was followed by an Americanized counterpart, ''VideoGame/EliteBeatAgents''. In May of 2007, it also got a full-fledged sequel with the [[LongTitle unwieldy title]] of ''Moero! Nekketsu Rhythm Damashii: Osu! Tatakae! Ouendan 2'' ("Get Fired Up! HotBlooded Rhythm Spirit: Hey! Fight! Cheer Squad!"), which featured new music, new scenarios, and a team of friendly rival cheerleaders from the upscale side of town. In addition, there is also a free PC clone called [[http://osu.ppy.sh/ osu!]], featuring user-created stages.

You can find a translation of the manga panels from the first game [[http://www.gamefaqs.com/portable/ds/file/928590/47789 here]] and the translation for the second [[http://www.gamefaqs.com/portable/ds/file/938402/48692 here]].
And just for fun: Computer desktop backgrounds for the [[http://www.nintendo.co.jp/ds/aosj/wallpaper/index.html first game]] and the [[http://www.nintendo.co.jp/ds/ao2j/download/index.html second game]]. There's [[http://inis.wikia.com/wiki/INiS_Wiki a wiki]] for the games (and other games made by [=iNiS=]), but you won't find much there.

Note: When we refer to the stages, we're using the title of the song featured in them, just like in the ''EliteBeatAgents'' page, because repeating the [[ExcitedTitleTwoPartEpisodeName Excited Title! Two-Part Episode Names!]] over and over again gets pretty tiresome.

----
!!This series provides examples of:
* {{Abhorrent Admirer}}s: [=JIN2=]'s fangirls are this in the bad ending of "Music Hour".
* TheAce: Junior in both games and ''EBA''. The last time, he just appears in a [[ItMakesSenseInContext middle-aged woman's fantasies]].
* AllJustADream: The bad ending of "Bang! Bang! Vacances".
* AllThereInTheManual: Some character info can be found on the official websites for the games, and some roughly translated versions can be found if you're willing to ArchiveBinge through the GameFAQs forums.
* AnimeHair: Ryuta Ippongi and Kai Domeki.
** Kai's hair is apparently spiky enough to break wood, as evidenced by "Shounen Heart".
** There's also Ryuji from "Thrill", obviously parodying Shonen series.
** Karizou Moriyama from "Julia ni Heartbreak" makes AnimeHair as a ''career''.
* AnimeLand / WorldOfWeirdness: There are HumongousMecha, {{Kaiju}}, {{w|olfMan}}erewolves, [[OurGhostsAreDifferent ghosts]], [[ColonyDrop occasional world]]-[[SolarCPR ending catastrophes]] and more concentrated in a [[TokyoIsTheCenterOfTheUniverse small part of Tokyo]]. Of course, that doesn't mean the ''[[EliteBeatAgents rest]]'' of the world is perfectly normal.
* AnimeThemeSong: Every level is backed by a different song, which has varying amounts of relevance to the action.
* AntiFrustrationFeatures: In the sequel, if you run out of health on Easy mode, the Hard mode cheerleader for the team you are currently playing as shows up and revives you with about 3/4 of your health so that you can continue the song. Run out of health again in the same song though, and it's GameOver. Of course, it won't work on the final levels, so you're on your own for that.
* ArsonMurderAndJaywalking: What the girls in Hiroshi's class do if you fail "Atsuki Kodou no Hate". They call him a lewd old man, a pervert teacher, a person who doesn't wash his clothes... and an idiot.
* ArtEvolution: The sequel features somewhat less cartoony proportions.
* ArtificialRiverbank
* AttackOfTheFiftyFootWhatever: The mouse {{kaiju}} in one of the later levels, as well as Ichiro Tamura, the {{salaryman}} who shows up to fight it so it won't harm his daughter.
* BadassArmFold: The guys in Yuuhi do this before starting a song.
* BadassBeard: Doumeki Kai has a badass ''{{anime|Hair}}'' beard.
* BadassCape: Kiryuuin Kaoru, his blue team counterpart, has a rather nice cape when he isn't cheering.
* BattleAura
* BattleInTheCenterOfTheMind: Takuya has to face all sorts of dilemmas in his mind, or else he'll wet the bed. Of course, RealDreamsAreWeirder, so the situations include the [[LawyerFriendlyCameo not-]][[SuperMarioBros Mario Brothers]] fixing pipes and giant sumo plugging dams in an AmazingTechnicolorBattlefield.
* BearsAreBadNews: There's one that appears in the sequel during the "Go My Way" level, where your target has to ''wrestle it'' into submission. It later appears in a cutscene in Hard Mode in one of the game's more... [[SugarWiki/FunnyMoments memorable moments]]. [[MoodWhiplash Right before the sad level.]]
* BeastAndBeauty: No matter what you do, [[MeaningfulName Goro Okami's]] girlfriend will eventually find out he's a werewolf. Fortunately, she thinks he's adorable like that.
* BeautifulAllAlong: [[OfficeLady Sachiko]] when you pass "Koi no Dance Site."
* BigEater: Anna has a brief stint as one in "Okoru Kotoba" judging by how large her bowl is compared to Aoi's and Sayaka's. Also, in the same song, when Kai notices that he and the others have to start cheering while they're in the middle of eating, he wolfs down the ''entire pot''.
* BigOMG: Dan and Joe yell "Oh! My God!" when you fail the first two sections of "Shanghai Honey".
* BigRockEnding: No better way to close out the final song of the second game.
* BilingualBonus: One for the Japanese players. In the second game, Ookami Gorou, the star of "Kibun Jōjō ↑↑", has "Wolfie" written on his shirt in English.
* BishieSparkle
* {{Bishonen}}: [=JIN2=] is this in [[BishieSparkle extra-sparkly]] flavour.
** Hayato Saionji could count as well, due to his [[LongHairedPrettyBoy waist-length hair]] and somewhat calmer-looking disposition. Shinta could also count if you don't think he looks ''[[ViewerGenderConfusion too]]'' girly.
* BitingTheHandkerchief: Junior does when you pass the second part of "Bang! Bang! Vacances!"
** The three fangirls in "Music Hour" also do this in the opening cutscene.
* BlandNameProduct: In the second failure scene of "Ready Steady Go", the MHK channel replaces the NHK. There's also a soccer tournament called the "Wild Cup".
* BlankWhiteEyes
* BrutalBonusLevel: "Samurai Blue", while not quite nearly as hard as the last level, definitely qualifies when 90% of the beatmap is made of eighth notes spaced like quarter notes.
* ButNotTooForeign: There are plenty of these in the sequel.
* CallBack: Hajime's pose before cheering in the sequel is exactly like Kai's pose in-between cheering segments in the original.
** In the second game, Takuya's parents in "Bambina" are the couple from the first game's "Melody". "Go My Way" in the second game features Shizuyama Kazebayashi, and the vase he makes at the end of the song (which turns out good if you do well in the song, and bad if you don't) calls back to the first game's "Kokoro Odoru", where the objective was to inspire him to create a good piece of work. His "Big bang!" catchphrase also shows up again. "Zenryoku Shōnen", the first song from the second game, is almost identical to "Loop & Loop", the first song from the first game, featuring the same target and a similar problem (trying to get into university in the first game vs. trying to get a job in the second game). Both songs' intros even consist of Tsuyoshi Hanada yelling at his family about his problems while they just laugh at him.
* CallingYourAttacks: Spoofed in "Thrill". "Tiger Smash!" "Dragon Thunder!"
* TheCameo: The announcer, the cops Joe and Dan, and "Junior" from "Koi no Dance Site" are the only characters in every game, including ''EliteBeatAgents''.
** The Elite Beat Agents and Tang Yao's cat also appear cheering in place of the Ouendan in OTO 2.
** There's also a slight chance that Tsuyoshi Hanada is in EBA, although there are some slight visual differences.
** There's even a LawyerFriendlyCameo by, of all people, the ''freakin' [[SuperMarioBros Mario]] Brothers.''
** Also, some of the targets of certain songs appear in the videos for the other songs. In the first game, Dan and Joe from "Shanghai Honey" appear in the ending of "Taisetsu na Mono". Shizuyama Kazebayashi from "Kokoro Odoru" appears in "Thrill", and the cat from "Linda Linda" appears briefly in the intro to "Melody". Also, if you fail the first section of "Over the Distance", Tang Yao from "Linda Linda" shows up. In "Linda Linda" itself, Tsuyoshi Hanada from "Loop & Loop", Sachiko from "Koi no Dance Site" and Hiroshi from "Atsuki Kodō no Hate" appear eating at the restaurant in the ending.
** In the second game, Ebi-yama from "Okuru Kotoba" appears in Takuya's dreams (and in a poster on his bedroom wall) in "Bambina".
* {{Catchphrase}}: Shizuyama Kazebayashi is really fond of yelling "[[GratuitousEnglish BIG BANG]]!"
* CherryBlossoms: At the end of every stage in OTO 2, and the end of the teacher's stage in OTO 1.
** Also, the menu tree and the trees along the river bloom into these when you finish all four difficulties.
** Also in the song "Glamorous Sky" in the second game, there is a girl actually ''named'' [[CherryBlossomGirl Sakura]]. And to make it {{meaningful|Name}}, she's the person that the (10-year old) target has a crush on who is being transferred to another school. In the second section of the song, the kid personally takes her to a (fake) blooming cherry blossom tree.
* ChristmasInJapan: "Samurai Blue" takes place during Christmas, and opens with the Asahi team selling Christmas Cake.
* CircleOfFriendship: Both games end with the inhabitants of Earth singing and dancing together to fire a giant hadoken of love and music at whatever was going to destroy the world.
* ClapYourHandsIfYouBelieve
* [[SchoolIdol Class Idol]]: Wakana in "Thrill" is labeled as such.
* ClubStub: The Versailles Academy choir club in stage 2 of OTO 2.
* CoincidentalBroadcast: The intro to the final level of both games.
* CombinedEnergyAttack
* ContinuityNod: Characters from earlier stages make cameos in other stages.
** And characters from the first game appear in the second as well. Takuya's parents are the couple you united in one of the first missions.
** Part of the entire map in the first game gets reused in the second, although a couple of changes were made to the surrounding area.
* TheCoverChangesTheGender: "Bang! Bang! Vacances" was originally done by boy-band SMAP. The game used female singers, likely to fit the scenario better.
** A similar thing happens for "Shounen Heart", but they make the singer an old man instead, for a similar effect.
* CrowdChant: "OUENDAN!!! OUENDAN!!!"
* CueTheSun: You did just save it, after all.
* CuteKitten: The cat has been a staple of the games, and even becomes a playable character if you cheer on the final level with the EliteBeatAgents.
* DarkHorseVictory: "Guts da ze!" Later having said darkhorse chase after a thief.
* DepartmentOfRedundancyDepartment: The Nobility's boat is called the Asahi Sunrise III. Asahi means sunrise.
* DetachedSleeves: The Cheer Girls' uniforms upgrade to this in the sequel.
* {{Determinator}}: Forget everyone else, Tsuyoshi Hanada practically tops all of them. He's failed his entrance exams and been rejected by employers 99 times ''each''. Not only that, his family normally treats him like crap. No wonder why he's so desperate in the beginning of the game.
* DifficultySpike: Most people have no problem with the game until the final levels. And Hard mode kicks the difficulty up a notch.
* DisappearsIntoLight: Rina does this at the end of "Believe".
* DissonantSerenity: The game overs for the last level involve the team(s) you cheered with [[GoOutWithASmile smiling]]. You know, after completely freaking out over the fact that the world is going to end and you couldn't do a damn thing about it.
* DistractedByTheSexy: Momotaro if you fail one section of "Shounen Heart".
* DistressedDude: JIN 2, who even in the final stage of OTO 2 needs to be saved by his middle aged fangirls from an incoming ice rain.
* TheDitz: If you notice, the {{Meganekko}} cheerleader girl Aoi Kanda just can't do anything right outside cheerleading, though [[AllThereInTheManual she's supposed to be able to speak around seven languages fluently.]]
* {{Dojikko}}: Aoi's {{Expy}} in the sequel, Honoka Kawai, faceplants in the ''menu screen.''
* DoWellButNotPerfect: If you don't succeed in a mission completely, but still survive, you get unique cinemas. More is explained on the other page.
* DullEyesOfUnhappiness: Sakura exhibits this in the beginning of "Glamorous Sky" because of her being required to move.
* EarlyInstallmentWeirdness: The second game has a lot more in common with EliteBeatAgents than the original engine-wise. No single-cart multiplayer or saving replays, for one.
* EiffelTowerEffect: Both games use this to show the all the world's people cheering together during their respective final levels. The [[{{Eagleland}} Statue of Liberty]] in particular shows up in both.
* EpicHail: Can you shout "Ou-en-DAAAAAAAAAAAAAAAAAAN!"?
* EverythingsBetterWithMonkeys: And what better way to illustrate this trope than the song "Monkey Magic," featuring a plush monkey that wants to get back to its owner?
** "Go My Way" has some monkeys in the opening scene, with the most appearing [[AllMenArePerverts near Sayaka.]]
* EverythingsBetterWithSpinning: Inverted. Spinning makes everything ''worse'' in this series, at least from the [[ScrappyMechanic player's perspective.]]
* ExpositoryThemeTune: The tutorial theme basically translates to "Cheer, cheer, cheer! Put your fighting spirit into it! Cheer, cheer, cheer! We are the Ouendan!
* {{Fanboy}}: Takuya from the same game seems to really like Ebi-yama, a sumo that you help cheer on. Not only does a dream version of him appear in the stage Takuya is in, the kid even has an Ebi-yama T-shirt and poster in his room.
* {{Fangirl}}: The three middle-aged fangirls of JIN 2 in OTO 2. And apparently, Honoka and Reika (the supporting rival cheerleader squad) may also be his fangirls, since they appear carrying a fan with his name (Honoka) and a {{Hachimaki}} with his name written (Reika).
* {{Fanservice}}: The HotSpringsEpisode opens with a ShirtlessScene. Ippongi is ''ripped.''
** Note that if you attempt this with the Cheer Girls, [[GettingCrapPastTheRadar the only thing censoring their breasts is the gap between the two DS screens.]] And that's without mentioning the cheergirls' ''[[{{Stripperific}} regular]]'' outfit...
** ForeignFanservice: Anna
* FestivalEpisode: "Melody" from the first game.
* FireForgedFriends: The squads couldn't exactly handle the heat death of the sun ''alone'', now could they? One bonus pic later reveals the squad members all got together for a picnic, with the Normal mode leaders in a heated match of... arm wrestling?
* FreakyIsCool: Thank God Kumi's a dog person.
* FunnyAfro: J-Yama in the "Taisetsu na Mono" stage of OTO 1. He has a special sort of hairspray that can give people these with a side order of becoming {{Brainwashed}}.
* FloralThemeNaming: All of the Nobility have this.
** There's also ''Yuri''a and Kaoruko ''Tsubaki'' from "Rirura Riruha".
* FlowerMotifs: Nanako, a character in one of ''Ouendan 2'''s multiplayer scenarios, has the [[http://en.wikipedia.org/wiki/Government_Seal_of_Japan Paulownia Seal]] on her tennis racket, to contrast with her {{rival}} Ageha's GemEncrusted ''{{gold|MakesEverythingShiny}}en'' one.
* GenderBlenderName: Kaoru is a man.
* GettingCrapPastTheRadar: Lots of times.
* GirlishPigtails / EveryGirlIsCuterWithHairDecs: Both "cute" cheergirls hit both tropes, and the Nobility girls all have some sort of hair accessory.
* GirlsWithMoustaches: Reika dons a fake one in "Samurai Blue".
* {{Gonk}}: [=JIN2=]'s fangirls. Christine Kamogawa's design counts as well, looking almost [[http://en.wikipedia.org/wiki/Superflat superflat]] compared to the more generic supporting cast.
* GratuitousEnglish: In the first game, "Melody" has this with the foreigners saying "Look! Matsuri? Help shimāsu!". "Shanghai Honey" has a crowd shouting "HELP!", as well as the subjects of the song, the police officers Dan and Joe, who are implied to be American (though they speak Japanese too) with "OH! MY GOD!" and "Good Job!" being used depending on whether you fail or win a segment. The last stage of the first game, "Ready Steady Go", has a New Yorker asking "What's" (no really, that's all the speech bubble says) regarding the oncoming meteor, and later the Americans scream "Oh! No!". There's even some GratuitousFrench in the same stage, with "Oh! Lala!" and "Non!" being used in the same situations. In "Neraiuchi", Cleopatra exclaims "YES!" if you do well enough on certain sections.
** In the second game, the monkey in "Monkey Magic" exclaims "Yes!" if you pass the part with the dog. The old man in "Shōnen Heart" says "Hello?" in the intro. In "Samurai Blue", the mice shout "Go!" if you do well enough in the first scene.
** Also in general, the Cheer Girls use this, saying "GO!!!" instead of "Osu!" and saying "3, 2, 1, GO!" in English at the start of every song.
* GunKata: Dan and Joe do this if you do well enough in the first two parts of "Shanghai Honey".
* HemisphereBias: The results screen of the final level in both games is a globe centered on Asia and Japan. In ''EliteBeatAgents'', it's on North America.
* HerCodeNameWasMarySue: The protagonist of Christine Kamogawa's novel in the "Bang! Bang! Vacances" stage is obviously supposed to be an idealized version of Ms. Kamogawa herself.
* HeroicSacrifice: The Yuuhi squad shove the Nobility out of an incoming ice block at the end of "Countdown". [[SugarWiki/HeartwarmingMoments Tears]], [[SugarWiki/MomentOfAwesome awesomeness]] and [[NintendoHard death]] ensue.
* HistoricalBeautyUpdate: Literally done with Cleopatra. She starts off as a fat {{Gonk}}, then uses pyramid power, miracle dances and the support of Japanese cheerleaders to make herself beautiful in order to impress Antony.
* HistoricalDomainCharacter: You get to cheer on a fat Cleopatra in one of the first game's levels.
* HotBlooded: We see the clients regaining their fighting spirit at the start of every stage, and you get some when you keep up the combo. It's also in the title of the sequel.
* HotbloodedSideburns: Look at the game's cover art. Those things could pierce a battleship. And Ryuuta's not alone when it comes to this trope either. Kai has them too.
* HotSpringsEpisode: There's one in the second game, complete with shirtless scenes of ''[[GettingCrapPastTheRadar all]]'' the(non-rival) leaders.
* HumongousMecha: Fuji-One in the "Zoku" stage of OTO 2.
* HurricaneOfPuns: Of course, they're all in Japanese, because [[CaptainObvious this was a game made for Japanese people]].
** To the point where the second to last line in the credits is "Thanks for your love and support!" In Japanese, the word for both "support" and "cheer" is ''ouen''.
* IdiosyncraticDifficultyLevels: The official names for the difficulties: Rather than Easy, Normal, Hard and Insane), we have Light-Hearted Cheering, Bold Cheering, Fierce Cheering and Magnificent Cheering.
* IncendiaryExponent: Seeing the series' [[HotBlooded main aesthetic]], it's not all that surprising when fire starts popping up in the background. Even [[LogoJoke the logos]] light on fire in the sequel.
* InvoluntaryShapeshifting: Poor Goro Okami has been cursed to transform in a wolf whenever he sees something round, white, shiny, or some combination of the three, which gets in the way constantly on a date with his girlfriend.
* IWishedYouWereDead: Mana Shiratori to her sister Rina. Guess what level we're on.
* JapanesePronouns: The first cutscene of "Countdown" changes the (plural) pronoun depending on the leader, with "boku-ra" on Easy, "ore-tachi" on Normal, "wareware" on Hard and "watashi-tachi" on Insane. The {{keigo}} used is slightly different as well.
* KansaiRegionalAccent: The target in the "VISTA" level, where he decides to sell shoes to aliens. He can also [[BatmanCanBreatheInSpace go to Venus without a helmet.]]
* {{Kawaiiko}}: Honoka [[PunnyName Kawai]], [[http://lparchive.org/Osu-Tatakae-Ouendan-2/Images/39-honokafull.gif of course]].
* {{Kiai}}: Pretty much the whole freaking game.
* LargeHamAnnouncer: The announcer is probably one of the larger hams in the game, despite only appearing in select levels.
* LetsPlay: Both games have been LP'ed by Tasian. Notable in that both [[BlatantLies claim to have an accurate English translation]]. Let's just say that's... [[GagDub not]] [[ThisIsYourPremiseOnDrugs the case]].
* LookBothWays: Rina sure didn't.
* LoudspeakerTruck: One level in the first game has the squad backing up the driver of one against an afro-sporting rival.
* LyricalDissonance: The lyrics to some of the songs don't really fit as well as they should. Some border on IntercourseWithYou.
* MadnessMantra: Christine Kamogawa starts frantically typing "Ouendan" repeatedly before yelling for them.
* MagicSkirt: Compared to the first game, the sequel features next to no chances for any accidental {{Panty Shot}}s.
* ManekiNeko: The cat mimics one of these in the end of "Linda Linda".
* MangaEffects: Pretty much all of them, since the games introduce each level with a sequence of manga panels.
* ManlyTears: on the final stage, by the [[ThoseTwoGuys sideline]] characters.
** Also shed by the entire Encouraging Nobility team at the end of "Believe" from OTO 2.
*** And the opening of "Sekai wa Sore wo Ai to Yobundaze" has even more tears from the Nobility!
*** And in the same stage, in a recreation of the scene from the first game's final stage, the backup cheerleaders from both teams shed the waterworks. Whether it's TearsOfJoy or [[TearsOfFear not]].
* MartialArtsHeadband: Some of the leaders wear this, but Hajime switched his for a NiceHat in between the first and second games.
* MeaningfulName: There are more than a few. Most notably, the Noble team in OTO 2 have names that mirror their rival's, and [[WolfMan Goro Okami]] had the misfortune to have a surname that could also mean "Wolf".
** More than that: each difficulty's leaders have a theme in their forenames. Easy has names that refer to inexperience, Normal has animal themes and Hard is basically a representative of what their team is like. Insane has FloralThemeNaming for everyone except [[PhenotypeStereotype the American]].
** Aoi Kanda's name is ''retroactively'' meaningful. As the cheergirls didn't get [[AllThereInTheManual profiles]] in the first game, the fact that she could speak multiple languages could reference the fact that [[http://en.wikipedia.org/wiki/Kanda,_Tokyo Kanda]] is a place in Tokyo known for its large supply of books.
* {{Meganekko}}: Aoi for a {{Moe}} example.
* MegaNeko: Nyaragon, from one stage in OTO 2. Possibly created as a counter to the giant blue mouse in OTO 1, and ''likely'' as a ShoutOut to ''EliteBeatAgents''.
* MinimalisticCoverArt: The first game's cover art leans toward this trope. Conversely, the second game's leans towards the [[DesignStudentsOrgasm opposite direction]].
* MomentKiller: Tan Yao can be a '''huge''' cockblock on certain levels.
* {{Mondegreen}}: The loud drum beats can seriously distort what some of the singers are saying, but even without them, people mistake "Can you master baby?" from One Night Carnival for... [[ADateWithRosiePalms something else]]. There's also "I wanna be a Pop Tart" for "I wanna be a Pop Star."
* MoodWhiplash: Notably averted - the sad stages have no "OUENDAAAAN!" cry, and the Ouendan themselves are completely silent throughout the stage. The first game's "Over the Distance" just has a quiet "Ouendan...", while the second game's "Believe" doesn't have anything at all.
** Also, after completing the stage, the "Ouen! Dai seikou!" cry is much, much quieter - and the cheer squad has tears on their eyes".
* MoralDissonance: Cleopatra stage: You cheer on Cleopatra so she can order her slaves around greatly!? Well, at least they get as fired up as she does...
** But what happens if you play the stage poorly? A hilarious bit of physical comedy, as with every other stage? No, the slaves die. Cue the uncomfortable laugh.
* [[MrImagination Ms. Imagination]]: Christine Kamogawa's entire level counts on her getting inspirations from her {{Imagine Spot}}s.
* {{Mukokuseki}}: Averted. Although it becomes somewhat less so in the second game, all the characters at least maintain realistic eye colours. You know they're doing a good job when the Japanese guy with [[http://lparchive.org/Osu-Tatakae-Ouendan-2/Images/28-hayatoface.png blonde hair and blue eyes]] still looks Japanese. Even the Americans have a few brunettes among them like Dan and Joe.
* NamesToKnowInAnime: Creator/KentaMiyake and MaiGoto as Kaoru and Sayaka, respectively. I guess [[Manga/FullmetalAlchemist Scar and May Chang]] decided that cheerleading was a good alternative to alchemy.
* NationsOfTheWorldMontage: In the final level of both games.
* NiceHat: Kai in both games, Hajime in the second.
** And like {{Raidou|KuzunohaVsTheSoullessArmy}}, neither take theirs off during the HotSpringsEpisode.
** However, Hajime briefly takes his off in "Julia ni Heartbreak", while Kai [[DeathGlare stares at you menacingly]] in the same song. It seems anyone attempting to take off his hat is a BerserkButton.
* NintendoHard: Compared to other rhythm games, the beatmaps themselves are actually pretty simple. What makes the game Nintendo Hard is the absolutely unforgiving life meter, which penalizes you greatly for missed notes, such that it only takes a few missed notes before you fail out, and even if you manage to survive at first, not only is it really hard to build your meter back up, but you can still fail out later because the meter is always decreasing when you're not hitting notes. Which, by the way, makes it possible to fail even if you are hitting all the notes, unless you're hitting most of them perfectly. Oh, and the final stages? They like to throw a lot of spinners at you, and then have you hit tricky note sequences after the spinners, which tend to make your hand a little shaky for some time afterwards...
* NoFlowInCGI
* NoNameGiven: The announcer has no given name, so everyone calls him... [[EveryoneCallsHimBarkeep announcer]].
* NostalgiaLevel: The second game's first level is almost exactly like the first game's, except with job applications instead of entrance exams. The target even looks the same despite ArtEvolution.
* OcularGushers: The Ouendan's [[ManlyTears MANLY TEARS]] in break scenes at the last stage of each game.
* OfficeLady: Sachiko in the "Koi no Dance Site" stage of OTO 1.
* OjouRinglets: Reika. Ageha, a multiplayer character, also sports these.
* OldSuperhero: Momotaro in the "Shonen Heart" stage of OTO 2.
* OmnidisciplinaryScientist: Dr. Shintarou Kuroiwa, the young genius physician from OTO 2, who can cure male pattern baldness. And give farm animals therapeutic massages. And repair microwave ovens. And make an entire island's inhabitants so healthy they burst with muscles, even the women and the elderly.
* OpenHeartDentistry: In the second game, a doctor is called to "operate" on a man's bald head, a horse, and a malfunctioning microwave oven.
* OurWerewolvesAreDifferent: They change if they see ''anything'' round.
* PantyShot: The female cheerleaders; especially noticeable in the first game.
* PartlyCloudyWithAChanceOfDeath: It rains right before the TearJerker of the second game.
* PastelChalkedFreezeFrame: Any time something sufficiently HotBlooded happens.
* PluckyOfficeGirl: Sachiko in "Koi no Dance Site" in the first game.
* PoseOfSupplication: Seen in many of the game over screens.
* PottyFailure: If you happen to fail "One Night Carnival" and "Bambina".
* ThePowerOfFriendship: What revives the Ouendan in the second game.
* ThePowerOfLove: The last level of the second game is literally set to a song called "That's What the World Calls Love!" The ending even has a guy yelling "LOVE AND PEACE" like crazy.
* ThePowerOfRock
* PreciousPuppy: The Nobility have a pet dog that appears in some levels.
* AProtagonistIsRyu: Ryuta Ippongi.
* PunctuatedForEmphasis: Overlaps with TitleScream (and even the title itself is this). "Osu! Tatakae! Ōendan!"
** Every time you complete a stage, the Ouendan shout "Ōen! Dai! Sei! Kou!" (literally "Ouen! Big! Suc! Cess!"
** And some of the songs have it too. "Sekai wa Sore o Ai to Yobundaze" from the second game notably has "Ai! To! Hei! Wa!" and then later in English: "Love! And! Peace!". The opening scene to that song also features a CrowdChant of "Ou! En! Dan! Ou! En! Dan!".
* PunnyName: Ookami Gorou. As anyone who's played ''VideoGame/{{Okami}}'' will tell you, "Ōkami" can mean "great wolf" if written with certain kanji. Also, changing the kanji for "rou" in "Gorou" and changing the first kanji to "Ga" would give it the meaning of "hungry wolf".
* ReasonableAuthorityFigure: The angel who deals with the recently deceased Ishida Tetsu has no problem letting him temporarily return to Earth so he can give his wife a proper goodbye.
* RedArmbandOfLeadership
* RedHeadedHero / FieryRedhead: Ippongi Ryuuta.
* RedOniBlueOni: Invoked with the team colours in the sequel.
* RivalsTeamUp: The last level of the sequel.
* RocksFallEveryoneDies: What happens if you get a Game Over on the final level in both games.
* {{Ronin}}: Tsuyoshi in the "Loop & Loop" stage of OTO 1.
* {{Salaryman}}: Ichiro Tamura a.k.a Ichiro-Man, in "Taiyou ga Moete iru" stage.
* SayMyName: '''OUENDAAAAAAAAAAAANNNNN!!!!'''
* SceneryCensor: See FanService above.
* ShoutOut: Considering how the games were made to lampoon as many JapaneseMediaTropes as possible in what is considered an E rating in Japan, some references were inevitable.
** "Koi no Dance Site" is a WholePlotReference to Cinderella, and "Monkey Magic" is a pastiche of WesternAnimation/ToyStory. The "Koi no Dance Site" section is even called "Cinderella Proclamation! Will Junior Turn His Face Toward Her!?" ("Cinderella sengen! Junior wa furimuku ka!?") in the game.
** There are also the plumbers [[SuperMarioBrothers that totally do not represent any other Nintendo-made plumbers in any way]] in "Bambina".
** "Taiyō ga Moeteiru" has a main character who's powers are similar to Series/{{Ultraman}}'s.
** The multiplayer tennis stage in the sequel could be seen as a shout-out to ''Manga/AimForTheAce''.
** Doumeki Kai's name is a reference to ''Manga/CromartieHighSchool'', one of the main influences of the art style.
* ShyBlueHairedGirl: Reika has the looks of one combined with {{Ojou}}. [[AllThereInTheManual Her profile]] states that she had just recently tried ''instant ramen''.
* ShyFingerTwiddling: Masashi does this when you pass the first section for "Glamorous Sky".
* SimilarSquad: The Encouraging Nobility to the original Ouendan.
* SkywardScream: To re-iterate: [[SayMyName OUENDAAAAAAAAAAAANNNNN!!!!]]
* SolarCPR
* SomethingElseAlsoRises: Momotarou's reaction if you fail the second scene of "Shounen Heart". [[DirtyOldMan Note this is after he sees two women bathing in a hot spring]].
--->'''Momotarou''': Whoa-! [[GettingCrapPastTheRadar Something I forgot is swelling up inside of me~!!]]
* SparklingStreamOfTears: Sakura does this when you pass "Glamorous Sky".
* StealthPun: The opening of "Zoku" on the hardest difficulty, featuring the cheergirls packing boxes. [[spoiler: You could say that [[ForeignFanservice Anna]] is the most stacked.]]
* TheStoic: In contrast with the Yuuhi Ouendan and even with his own squad, Kaoru is rather mild mannered throughout the sequel. Of course, like the rest of the Nobility, he has his NotSoStoic moments at the end of "Believe" as well as in the last two songs of the game.
* {{Stripperiffic}}: Not so much for the cheergirls in OTO 1, but in OTO 2, it becomes obvious since they get more revealing costumes.
* SuperRobot: "Zoku" from the second game has the team cheering on a mechanics team trying to rebuild their HumongousMecha. To defeat the giant {{Kaiju}} cat rampaging the city, the robot must defeat it in a footrace, arm wrestling, and [[http://www.proz.com/kudoz/japanese_to_english/education_pedagogy/1149644 Hundred-Square Calculations]].
* TestosteronePoisoning: For a game series [[UsefulNotes/MediaClassifications rated A in Japan]], definitely. The art style alone was influenced by ''Manga/FistOfTheNorthStar'' and ''Manga/CromartieHighSchool''. The theme of the games is ''passionate love'' ([[FreudWasRight Not in that way!]]).
* ThemeMusicPowerUp: Obviously.
* ThemeNaming: The IdiosyncraticDifficultyLevels all start with "k". [[note]]"Gekiretsu ni Ouen" technically counts, as the "g" sound is a modified "k" in Japanese.[[/note]]
* TheThingThatGoesDoink: In the intro to "Kokoro Odoru".
* ThinksLikeARomanceNovel: Christine Kamogawa from "Bang! Bang! Vacances!" in Ouendan 2.
* ThoseTwoGuys: Part of the PowerTrio in each difficulty play. Also Joe & Dan the policemen.
* TimeSkip: Six years between the two games.
* TitleDrop: During the endgame of ''Ouendan 2''.
** Also during the tutorial theme, also played during the ending of both games.
* TrademarkFavoriteFood: Reika and ramen.
* TrainStationGoodbye: "Glamorous Sky" in OTO 2.
* {{Tuckerization}}: One of the backup cheerleaders, Atsushi Saito, is named after the character designer.
** And the other backup, Ittetsu Suzuki, is named after the chief animator. In other words, {{Tuckerization}} ''ThemeNaming''.
* UnderdogsNeverLose: Because they have your support. Hopefully.
* UnstableEquilibrium: The scoring system. Your score multiplier for each note hit is directly proportional to your current combo. Break combo at the beginning or end? No big deal. Break combo in the ''middle''? RageQuit!
* UnusualEyebrows: Mainly of the Fiery variety, although Ryuuta sports some impressive Lightning brows.
* UrineTrouble: On some levels, notably "Linda Linda", a kitty tends to do his business near the target, especially if the Ouendan aren't doing well.
* VerbalTic: Tan Yao says "aru" a lot after sentences, which is usually an indicator of a Chinese person.
** Monkey-kun's toy soldier partner has "de arimasu," which is a very military way of speaking. Or maybe a "Shout Out" to a certain [[KeroroGunsou sergeant]] too.
* WeaksauceWeakness: The robots from "Shanghai Honey" are weak to water. And decide to invade a planet that's two-thirds made of it. And start their invasion on an ''[[WhatAnIdiot island nation]]''.
* WholePlotReference: Replace "music-hating alien invasion" with "The Sun is dying" and "[[TakenForGranite petrifying]] death beams" with "falling chunks of ice", and the final stage of the second game is almost shot-for-shot identical to ''EBA'''s.
* WidgetSeries
* WolfMan: Gorou Ookami in the "Kibun Jōjō ↑↑" stage of OTO 2.
* WorldOfHam: You don't say?
* YamatoNadeshiko: The goal of "Go My Way" is to turn an [[WrestlerInAllOfUs ex-wrestling champion]] into this.
* YouGottaHaveBlueHair: Aoi's is pink for no apparent reason. The sequel also brings us Rin and Reika, along with one of JIN 2's {{Fangirl}}s.
* YouHave48Hours: Tetsu in "Over the Distance" is given three hours to apologize and say goodbye to his wife before he has to return to Heaven.
* ZettaiRyouiki: The rival cheergirls have a respectable grade B.
