[[http://tyrantking.net/yukari-is-free/ Yukari is Free]] is an interactive role-playing story set more or less in the Manga/AzumangaDaioh universe, with multiple crossovers to whatever the players happen to be interested in at the time thrown in as well. It is currently in Season 4.

'''Season 1'''- The first season began with Yukari Tanizaki suddenly deciding to kill her class, and their attempts to stop her/escape. The story then moved into the afterlife, as one by one the students either fell victim to her or to their own stupidity, and they began trying to find a way to return to Earth before it came time for their souls to be judged and assigned to an eternity in either Heaven or Hell.

'''Season 2'''- After successfully returning to Earth with no memories of the afterlife, the group faces an evil alternate dimension version of Chiyo-chan followed by a nation-wide zombie apocalypse. Tomo's sister [[{{Yotsubato}} Torako]] joins the cast, Kaorin becomes an antagonist when Sakaki rejects her to be with Kagura, and Torako and Tardboy accidentally become porn stars after a video conference system films them having sex and broadcasts it all over Japan. After a series of close calls, which included the collapse of Japanese society, they are finally able to reach safety and are evacuated to Hawaii.

'''Season 2.5'''- A {{Breather Episode}}, with the cast now living in Hawaii. Torako and Tardboy are trying to get used to being celebrities, and Tomo and Yomi are trying to film a porno of their own to get a piece of the action. Meanwhile a remnant of the evil Chiyo awakens and begins exerting control, Asagi begins trying to force Tomo into being her submissive sex partner like her sister was before her, Kagura becomes a celebrity in her own right, and Nyamo reveals that she is pregnant after drunkenly having sex with Kagura's father in Season 2. The season comes to an abrupt end when Tardboy is kidnapped, and Torako is shot and nearly killed trying to protect him.

'''Season 3'''- The longest yet. Things are kicked off when Kagura is kidnapped by the same group who took Tardboy, leading the group back to Japan to rescue them both. Once there they encounter post-apocalyptic mech gangs, communist terrorist organizations, missing friends and family members, evil robot scientists, and the United States military, not to mention the big bad villain of them all: a nefarious clone-spawning pornography company straight out of Hell. The season finally ends with the cessation of hostilities between the United States and Japan, and much of the cast's evacuation (or return, in some cases) to Hawaii.

'''Season 3.5'''- Another breather episode, with much of the cast either getting into [[HilarityEnsues wacky hijinks]] or just trying to relax after the insanity of the last season.

'''Season 4'''- Just started, and expected to deal with the cast fighting off an AlienInvasion.

Not to be confused with [[VideoGame/{{Touhou}} Yukari Yakumo]] [[BreakingTheFourthWall is free.]] Is Canceled.
----
!!This confusing trainwreck contains examples of the following tropes:
* AcePilot: A fairly good percentage of the main cast.
** Torako, Tomo, Tsuruko, Kagura, and most other mech pilots mainly fall under the Steamroller type.
** Sergeant Greene seems to mostly be a Bushwhacker with dashes of Sniper and Plugger mixed in as well.
** Female Gang Member is a mixture of Steamroller and Plugger.
* ActionGirl: Also too many to list... [[AuthorAppeal a number of Social Disaster's female characters fall under this trope.]]
--> "If [=YiF=] were a sci-fi series he'd be Ron Moore."
* ActionGirlfriend: Torako is this to Tardboy, and Sergeant Greene is apparently on her way to becoming one to Koiwai.
* AirborneAircraftCarrier: Crazy Julio is an airship controlled by the brain of the illegal arms dealer who stole it. Kagura's ship, the Dai Kagurren, is capable of flight as well.
* AliensAreBastards: Season 4 is expected to fall under this.
* AliensSpeakingEnglish: Mark can speak any language with impeccable fluency.
* AlphabetNewsNetwork: "Otaku News Network," apparently the only news station to survive the near-total collapse of Japanese society between Seasons 2 and 3. Home of a HotBlooded screaming weatherman and the ubiquitous [[CatGirl Catgirl News Anchor]].
* AnachronismStew: The story is explicitly set in 2010, yet many examples of extremely advanced technology such as [[HumongousMecha giant war mechs]] ([[ArtificialIntelligence individual personalities]] optional), [[AirborneAircraftCarrier giant airships]], [[InvisibilityCloak invisibility cloaks]], and DeflectorShields are all apparently commonplace enough not to warrant too much of a reaction. [[RuleOfCool No effort whatsoever is made to explain or justify this]].
* AndIMustScream: Combined with BodyHorror in the first season when the girls are told that, if sent to Hell, they will be compressed into human bricks and used as building materials, spending the rest of eternity fully conscious and in constant agony.
* AppropriatedAppellation: Torako and Kagura were given their stage names by an evil porn company that had distributed [=DVDs=] of them in...compromising situations.
* ArtisticLicenseBiology: Combined with InsaneTrollLogic when Tomo insists that since she and Torako are twins, that means they're essentially clones, and therefore any sexual contact between them is only masturbation, and not incest. Yeah.
** Also, Gang Member 122 and Miura both seem to think that alligators are lizards.
* ArtisticLicenseGeography: When Sergeant Greene mentions being from [[DownOnTheFarm Iowa]], Kyoto mimics a banjo in reference to the DeepSouth.
* AscendedExtra: A great many characters originally introduced as background filler, including Gendo Yamane, Tetsuo Matsuoka, Chie Togusa, Ai Tanagawa, Shinji Ryougi, Ran and Rei Kakizaki, and nearly every other gang member to appear after the third season.
* AttemptedRape: Kyoto's first appearance has him trying to have some fun with Osaka. Because she was injured in the first place anyway he very nearly got away with this...Until Yukari distracted him. With her fist.
* AwesomeMcCoolname: According to the Shenanigoats threads, Tardboy and Torako name their daughter ''Chainsaw.''
* AxCrazy: Stay away from Yukari. Seriously.
* BackForTheDead: Haru at the start of Season 3.5, reintroduced for the sole purpose of being vaporized. Her companion Karii apparently [[PutOnABusToHell got it even worse]].
* BadAss: While many characters certainly qualify Torako takes it over the top, annihilating hordes of ravenous zombies using only her bare hands in Season 2 and single-handedly taking on entire mech gangs in Season 3.
* BadassFamily: The Takinos are all absurdly naturally talented mech pilots, with the exception of the father Tsuguhiko.
* BerserkButton: Elesia and Sasuke are ''very'' protective of Rei. Hurt or threaten her at your own risk.
* BiTheWay: The Takino sisters, Sakaki, Matsuda, Chihiro, and Asagi are all bisexual, and Rachel and Kaorin may be as well. While Tomo and Asagi could definitely be called depraved, it has very little to do with their sexuality.
* BigDamnHeroes: The RED Pyro gets one when he saves Fuuka from the BLU Spy.
* BlackComedyRape: Tomo and Yomi ganging up on Torako.
* BlindingBangs: Ran Kakizaki/Gang Member 114 wears her hair like this because her eyes are extremely light-sensitive. Her little sister Rei/115 has them on occasion too.
* BloodIsTheNewBlack: Since Torako's preferred method of dealing with zombies in Season 2 was ''ripping them apart with her bare hands,'' pretty much every major fight scene invariably ended with her covered in blood. How she managed to avoid becoming infected with the zombie virus herself is anyone's guess.
** See also Season 3, when Shimauu got Sergeant Greene's blood all over herself.
* ABoyAndHisX: Chiyosuke and his robot pal Floaty, especially after she betrayed [[VideoGame/{{portal}} GLaDOS]] and saved everyone. [[spoiler:Too bad he went too far and accidentally destroyed her when she went rogue again... while carrying [[LivingToy Toaster's]] program]].
** Though not a boy, Shimauu and Six could qualify as well.
* BreakingTheFourthWall: Occasionally. Mainly by Wallaby and Asagi.
* BreakTheCutie: Kagura in most of Season 2 and up until her [[spoiler:resurrection]] in Season 3. Many of the gang members could also qualify, given what they'd survived.
** Notable mentions include Ran, Rei, and Kanako..
* TheCameo: David Bowie makes a brief appearance as a zombie early in the second season...before being run over by Yukari.
* CanonDiscontinuity: Shin-Chiyo's rampage across North America, resulting in widespread destruction across the central United States and the separation of Florida from the rest of the landmass. (At which point it [[ArtisticLicenseGeology drifts off into the ocean]].)
** [[SonicTheHedgehog Knuckles and Robotnik]] in Season 2? What are you talking about?
* CannotStandThemCannotLiveWithoutThem: Sums up Yanda's feelings for Asagi.
* CatGirl: Two of them: the Catgirl News Anchor is just an anchorwoman wearing fake cat ears, while Hula Hoop is a Feline-Human Hybrid created by a MadScientist via splicing the DNA of his daughter and his cat.
* TheChewToy: Kagura in Season 2 and up until [[spoiler:her death and resurrection]] in Season 3; Fuuka, Shimauu, and Sergeant Greene played the role for the remainder of the season.
** Also any character played by Crimson Assassin. See for example Tsuguhiko Takino who has, in no particular order: been exposed to the fact that his daughters are bisexual ''and'' incestuous with each other, blinded but could hear, deafened but could see, became a paraplegic amputee after falling through the staircase of an abandoned high school, thought his daughter had been blown to bits, one could go on and on...
** Season 3.5 doesn't seem to have a designated Chew Toy yet, though Padudu and Shimauu seem to have a pretty good shot at the position.
** Shinji Ryougi would probably count, if it weren't for the fact that he willingly and more often than not ''knowingly'' jumps into bad situations.
* ChildProdigy: Chiyo-chan.
** Chiyosuke used to be this, but too much time around his new foster family seems to have whittled his mind away, replacing his smarts with wonderful memories of Kagura and Sakaki in bathing suits.
* ChuckCunninghamSyndrome: Anyone remember Yomicron?
** See also the mercenaries who were after Torako.
** And Mayaa. Lampshaded in the filename of his first appearance in Season 3.5.
** BLU Pyro as well.
* CombatPragmatist: Torako, Ai, Mark, and many others all fully endorse the use of cheating and dirty tricks in order to win a fight.
* ContrivedCoincidence: ''All the freaking time,'' and usually [[LampshadeHanging lampshaded]] to Hell and back when they occur. Examples include Tsuruko just ''happening'' to get assigned as Koiwai's roommate on a military base before being sent of a mission that just ''happens'' to lead to her running into the main cast, and the test subject that Chie rescues from the Undisclosed Location just ''happening'' to be Yomi's mother.
* CoolBigSis: Kagura to Chiyosuke, Sergeant Greene to Shimauu.
* CoolStarship: Mark's Warbler.
* CovertPervert: Sakaki has quite the dirty mind.
** Ran Kakizaki was a chronic masturbator who according to the discussion threads liked getting off in public bathrooms, and Amber Greene apparently knows Kagura, Sakaki, and Torako from downloading (and...ahem...''enjoying'') their sex tapes.
* CrapsackWorld: Japan in Season 3.
* CrossoverCosmology: The Mizuhara Shrine of Jesus Christ and Buddha, [[ExactlyWhatItSaysOnTheTin which incorporates elements of Christianity and Buddhism]].
* CupidHatesOddCouples: Kokoro has a crush on Mark, which develops after he breaks up with Fuuka. When she sees just how much he still loves Fuuka, she plays a pivotal role in reuniting them.
* CurbStompBattle: Torako's first encounter with the Yotsuba Gang, and again when the Yanda Gang tried to capture Kagura to turn her over to the BigBad.
* CuteGhostGirl: 2nd, although she is able to manipulate physical objects.
* DontSplitUsUp: In Season 2 at the outbreak of the zombie apocalypse, Tomo led her friends on a daring mission across town to rescue Torako at her school. Unfortunately Torako had the same idea, and was long gone by the time they got there.
* DownerEnding: Part seven of the third season ended with [[spoiler:Sakaki returning to patch things up with Kagura, only to find out she'd been killed in the big rescue mission]].
* DroppedABridgeOnHim: After Passerby left, his [[TheScrappy unpopular characters]] [[spoiler:Sakakuro, Kyoto, and Moto]] were all unceremoniously killed off-screen.
** See also the fates of Haru and Karii (along with much of Alaska) at the start of Season 3.5.
* DrugsAreBad: Some of the cast members, like Pyro and Heavy, have freaked out and wrecked the place because they got high. This could be attributed to the fact that Matsuda's home-grown pot is so strong that ingesting enough of it causes the hallucinations to become real. [[spoiler: In the words of Imaginary Billy Mays, "the pot so strong, it makes other people hallucinate!"]]
** Matsuda's the biggest exception to this. Normally insecure and snarky, Matsuda turns into a more friendly and mellow person after she's had a puff or two.
** Inverted by most of the other cast members however, as several including Kagura, Torako, Moto, Tardboy, Ryougi, and Ai seem to enjoy recreational drug use on a regular basis without any negative side effects whatsoever.
*** [[MushroomSamba Don't let Kagura take any Vicodin, though]].
* EagleLand: Ena is thrown for a loop when Sergeant Greene and Captain Mencia are ''not'' walking textbook examples of this trope.
** However, most of the American soldiers do still fit this trope, especially RED Team's Soldier.
* EmbarrassingNickname: Gang Member 37 ''hates'' being called "Ai-chan." She herself tries to invoke this trope by repeatedly calling Sergeant Greene "Twinkie," but it never seems to get the reaction she's hoping for.
* EverybodyHasLotsOfSex, except for Yotsuba, and unfortunately Osaka....[[OverlyLongGag and Chiyosuke, Ena, Miura, Elesia, Kokoro, Shimauu, Rinko, Rei...]]
* EvilTwin: Shin Chiyo, Fake Yomi and Doppelkeeper.
* ExpospeakGag: [[VideoGame/{{portal}} GLaDOS]] refers to everything in the most complicated way possible.
* {{Expy}}: Inevitable, considering many of the characters are represented by images from various anime and manga (And in some cases will have traits or abilities inspired by their origin).
* ExtremeDoormat: Ran Kakizaki normally wouldn't hurt a fly and seemed incapable of speaking above a whisper, let alone raising her voice in anger. This only made it all the more disturbing when she threatened to straight-up ''murder'' Member 92 if he ever came near her or her sister again.
* {{Fanservice}}: Cha-ching!
* FatGirl: Fuuka, by the start of Season 3.5.
* FellOffTheBackOfATruck: Used by Tetsuo to explain how the Yostuba Gang got their fleet of HumongousMecha in Season 3.
* FlatWhat: Rachel lets out a good one of these when That Kid casually surfaces from and exits a, ahem, ''soiled'' pool... a good ten minutes after everyone else had left.
* FootPopping: When Torako finally rescued Tardboy and freed him, the two share this moment. Tardboy was the one lifting his leg.
* FormerTeenRebel: A major source of the drama between Tsuruko and her daughter Torako is the former's fear that the latter has been following in her footsteps as a juvenile delinquent.
** Sergeant Greene was apparently prone to misbehavior during her younger years as well.
* FunetikAksent: Crops up somewhat inconsistently when the Japanese characters speak English, usually to illustrate how bad they are at it. Also played up for maximum absurdity with the Russians' ridiculous accents in Shenanigoats.
--> '''[[RedScare Olga]] [[PsychoLesbian Dykinsky]]:''' Beesidess, eef you shoot me end mek me repawn een Roossia you are oonly doink what [=SoDa=] woonts, becoos he ees ti-ehred off typink out my seelly fake Roossian eccent.
* GenreSavvy: Not that it does them much good.
** Played with when characters know doing something is stupid, explicitly comment on it being stupid, and then do it anyway.
* GoodPeopleHaveGoodSex
* GrandTheftPrototype: Kagura stole her mech out of the hangar of the Big Bad's walking battleship, and later the heroes take it up a notch by stealing the ship itself.
* GrievousHarmWithABody: During her introduction in Season 2, Torako ripped off a zombie's arm and used it to beat its master so badly that ''his'' arm fell off
* TheGunslinger: Almost everyone uses a gun at some point, but Ena's proficiency with firearms is disturbing.
* HappilyMarried: Tsuguhiko and Tsuruko Takino.
* HauntedTechnology: Toaster "talks" to people using toast.
* HeelFaceTurn: Chie Togusa/Female Gang Member is a government agent originally assigned to bring down the Yotsuba Gang from within, but she switched sides after bonding with its members and falling in love with the second in command. Of course, her employers suddenly deciding to kill her certainly made the decision easier as well...
* HeterosexualLifePartners: Gang Members 1 and 2 have been implied to be this.
* HilariouslyAbusiveChildhood: Among other things, Tardboy's mother used to lock him in a cage in the basement and made him wear a leash at parent-teacher meetings.
** Kokoro's adoptive parents never gave her a birthday, despite sounding fairly loving otherwise.
* HumongousMecha: Where the heck did they all come from, anyway?
* ICallItVera: The American mech pilots name their Arm Slaves.
** Somewhat justified in that the more advanced models are equipped with [[ArtificialIntelligence sophisticated AIs]], and at least some of the pilots treat them more like partners and copilots than war machines.
* IJustWantToBeNormal: For most of the cast, no one wanted to be caught up in the affairs of demons, the undead, furries, aliens, and evil corporations and corrupt governments, but too bad Yukari had to light the figurative powder keg.
* ISoundLikeARetardInEnglish: Despite living in the United States for four months between Season 2.5 and Season 3, only a handful of the Japanese portion of the cast can string together a decent sentence in English, let alone carry on a conversation. Especially shameful considering that they were learning it as a second language in school before everything went to hell.
** They seem to have improved by Season 3.5, though.
* TheImmodestOrgasm: This seems to be the default setting for the majority of sexually active females in the cast.
* ImpaledWithExtremePrejudice: [[spoiler:Tsuruko]] does this to Lady Kimura.
** [[spoiler:Floaty could qualify after getting drilled through by Chiyosuke.]]
* InnocentInnuendo: When Jumbo overheard Fuuka and Shimauu trying to force a futon into a laundry machine, he immediately assumed they were having kinky lesbian sex.
* InsaneEqualsViolent: Based on some of her comments and behavior, it sometimes seems as though Ena is just one poorly worded comment away from a psychotic shooting spree.
** Rei and Kokoro, however, are more or less harmless under most circumstances.
* InstantExpert: How can these people be so good at piloting advanced combat mechs with absolutely zero training, anyway?
* InterspeciesRomance: Anyone who gets romantically involved with Mark, since he's from another planet.
* JerkAss: Tomo, Ai Tanagawa, and Ren Tsutenpi all qualify.
** Fuuka has been having Jerkass tendencies more and more freqently as the story goes on. Mostly around Kokoro.
** Six seems to place people in two categories: Shimauu, and targets for abuse. And even Shimauu isn't exempt from his jerkass tendencies.
* JerkWithAHeartOfGold: Tomo and many members of the Yotsuba and Yanda Gangs and RED Team.
* JerkWithAHeartOfJerk: Again, Ai Tanagawa. She's not a very nice person.
** Li Wei Yang seems to be giving her a run for her money in the bitch department.
* KansaiRegionalAccent: Risu and Ayumu Kasuga, Kasumi Chiba, and the Greene sisters.
* KillEmAll: Yukari's homicidal rampage at the start of Season 1.
* KnifeNut: Gang Member 122's Knife is one of his prized possessions, this also counts as a [[BerserkButton Berserk Button]] for him. As Yukari finds out during their third encounter, and second fight.
* TheLadette: Sergeant Greene and Ai Tanagawa.
* LampshadeHanging: ''Constantly.''
* LaserGuidedKarma: Fedt-geszhine called a random space pirate "filth," and then dumped garbage over her head. She then stole the MacGuffin he was there to collect, [[NauseaFuel vomited all over him]], and got away after destroying several of his fleet's warships.
* LastNameBasis: Not even Koiwai's girlfriend or his children (one of whom hasn't been born yet...long story) seem to know what his first name is.
* LetterMotif: All the Takinos have a name starting with T and ending with O: Tomo, Torako, Tsuguhiko, and Tsuruko.
** Strangely enough, Kokoro only half fulfills this.
* LoadsAndLoadsOfCharacters: to the point where certain people involved have been forbidden from trying to introduce any more.
* LongLostSibling: To the point where it's been joked that eventually it will be revealed that ''everyone'' is related.
* LoveTriangle: Kaorin, Sakaki, and Kagura in Seasons 2, 2.5, and 3, and [[PuppyLove Chiyo, Chiyosuke, and Ena]] in Season 3.5.
** And also starting in 3.5 both Elesia and Rei have feelings for Sasuke, though in Rei's case she's so sheltered and innocent that she doesn't fully realize it.
* MadeOfExplodium: Turtles, apparently.
* MagicalGirl: Padudu would easily qualify. Kokoro seems to be this, as much as she [[AMindIsATerribleThingToRead doesn't want to]].
* MayDecemberRomance: Ryusuke is at least twelve years older than Nyamo.
** Saburo Motani, age 32, and his quasi-girlfriend Yoko Tsumura, age 21, also qualify.
** And as a particularly creepy example, Yukari's relationship with Kyoto; she's 29, and he was ''15.''
* MasculineGirlFeminineBoy: Tardboy and Torako.
* MegaCrossover: With ''Manga/{{Yotsuba}}'', ''Anime/CodeGeass'', ''Anime/TengenToppaGurrenLagann'', ''LightNovel/FullMetalPanic'', VideoGame/{{Touhou}}, and ''Anime/GhostInTheShellStandAloneComplex'', just to name a few.
* MenAreTheExpendableGender: If only one of a character's parents are revealed to have survived the ZombieApocalypse, odds are overwhelmingly in favor of it being the mother. With the exception of Ryusuke, fathers seem to survive as a set with their wives or not at all.
* TheMilkyWayIsTheOnlyWay: Averted; intergalactic distances seem to pose no problem at all to the most widely-used methods of FasterThanLightTravel.
* TheMole: Floaty tricks the group into trusting it early in season 3. [[spoiler:She later kidnaps half the cast for testing at the enrichment center]].
* MoodWhiplash: Yukari is Free is all over the map, constantly switching back and forth from comedy to drama to action to borderline hentai and everything in between, often playing multiple scenes in multiple genres simultaneously.
* MurderTheHypotenuse: Kaorin was madly in love with Sakaki, who was in love with Kagura. You can guess what she decided needed to be done.
* MushroomSamba: Kagura experienced one of these in Season 2 after having a bad reaction to Vicodin. She was later stabbed by Osaka as ''she'' was in the middle of a Vicodin-induced trip.
* NearDeathExperience: [[spoiler:Torako]] at the end of Season 2.5 when she is shot trying to prevent [[spoiler:Tardboy]]'s abduction, and in Season 3 [[spoiler:Ai]] is shot defending the Dai Kagurren from BLU Team and [[spoiler:Sergeant Greene]] is shot by [[spoiler:Yukari]]. All come very close to dying, and one even winds up in the afterlife for a few minutes.
** Kokoro had one when she was gutpunched by Torako for endangering the entire group's lives. She had a brief out of body experience, and then it [[BigLippedAlligatorMoment was never spoken of again]].
* NGOSuperpower: The cast could almost be considered one of these, what with their fleet of HumongousMecha, AirborneAircraftCarrier, CoolStarship, and the presence of at least one PersonOfMassDestruction among their ranks.
* NiceGuy: Member 2, Koiwai, and Ryusuke Kagura fall under this, and Sergeant Greene could be considered a female example.
* NighInvulnerability: Ghostmaster just. can't. ''die.''
* NoBisexuals: Averted. At one point over half the main female cast was bisexual.
* NoFourthWall: Played with in the behind the scenes discussion threads and omake-style "Shenanigoats" threads, in which characters frequently comment on the story or complain about their treatment at the hands of the writers.
* NotIfTheyEnjoyedItRationalization: Though she wanted no part of it at first, [[spoiler:Kagura]] eventually started to get into it when [[spoiler:Nyamo]] decided to have her way with her. Unfortunately for everyone involved, [[spoiler:Sakaki]] managed to walk in right as she was starting to enjoy it. Hilarity did not ensue.
* NumericalThemeNaming: The members of the Yotsuba Gang are numbered in the order that they joined up.
* ObligatoryWarCrimeScene: An odd example crops up near the end of Season 3, when Sergeant Greene ''prevents'' one of these from happening by shooting down Ryougi's suggestion that they simply execute the surrendered JSDF soldiers and instead orders them loaded onto the good guys' AirborneAircraftCarrier and transported to safety. She is then told upon reuniting with the Army forces that she hadn't been expected to take prisoners, essentially meaning that her superiors ''wanted'' her to risk committing a war crime by leaving surrendered [=POWs=] to die from exposure to lethally radioactive fallout.
* OneSteveLimit: Averted. So far there are two Randalls (with a third apparently to be introduced next season), two Samanthas, and two other characters named ''K''asumi and ''H''asumi.
* OppositesAttract: A few couples are notable opposites of each other. Yanda/Asagi, Torako/Tardboy, and especially Fuuka/Mark to name a few.
* OurAngelsAreDifferent: At least some of them are apparently just human souls who got "promoted" and are tasked with helping the recently dead adjust to the afterlife. Kagura's mother became one of these, and even wears a t-shirt identifying her as "STAFF."
* PersonOfMassDestruction: Yukari AIMS to become this. By whatever means necessary.
** Mark accidentally blew up an entire ''planet.''
* PleaseWakeUp: Rei's reaction to [[spoiler:her sister]]'s death.
* PlotArmor: At one point in the story, the entire cast went up against several giants with [[MoreDakka Akimbo Gatling Guns]]. No one even got seriously hurt.
* PolarOppositeTwins: Tomo is short, loud, hyperactive, and bossy, while her fraternal twin sister Torako is tall, laconic, and submissive.
* ThePollyanna: Yui Morishita/Gang Member 183 may have lost her entire family and all her friends in a horrifying zombie apocalypse and a devastating earthquake that nearly obliterated Japanese society, but you'd never tell that by looking at her. The reason for her eternal happiness? Brain damage from an untreated head injury she sustained during an Air Force bombing raid.
** Tsuguhiko keeps this trope up in a slightly more moderate sense, despite everything he finds out about his daughters.
* PrecociousCrush: Yanda seems blissfully unaware of Ena's crush on him.
* PunyEarthlings: Both played straight with the damn-near-perfect Veluszhi and averted with most other sentient races encountered so far. For example the Mo'e-Mo'e develop much faster than humans and have much more efficient respiratory systems than we do, but that just also makes them more susceptible to certain airborne toxins and gasses and they only live an average of sixty years. That, and they're all under five feet tall. Meanwhile the Dhugarl come from a high-gravity world and as a result are much stronger, faster, and more resilient than we are, but their high metabolisms and inefficient digestive systems mean they tire quickly and need to frequently gorge themselves to avoid starvation. And then there's the Altarians, who for all intents and purposes ''are'' human.
* RandomEncounters: Some random bouts of violence the heroes had fought in their adventures included, but won't be limited to, random demons (Season 1), hordes of decrepit non-descript zombies led by an overpowered super zombie and their undead queen (Season 2), an army of crazed furries led by a demonic deity trapped in a Kigurumi costume (Season 2), and random enemy mech patrols (Season 3).
* RapeAsDrama: [[spoiler:Nyamo]] forcing herself on [[spoiler:Kagura]] in Season 3.
* RealityWarper: 2nd is a minor version, usually.
* RelationshipUpgrade: [[spoiler:Ryusuke's marriage proposal to Nyamo.]]
* RevengeByProxy: Daisuke was angry at Ryougi for making him look like a cowardly idiot, so he [[spoiler:took the virginity of Ran]], who he knew Ryougi had a crush on.
** According to comments in one of the discussion threads if other things hadn't come up he would have tried to do this ''again'' (possibly crossing the MoralEventHorizon in the process), by deflowering Rei as revenge on Ran for...Ryougi getting angry that he had taken advantage of her.
* RubberForeheadAliens: Several examples. The Mo'e-Mo'e resemble [[PointyEars pointy-eared human children]], though there are significant anatomical differences below the neckline. The Kran look like ''adult'' pointy-eared humans, and are apparently anatomically similar enough for their females to have breasts, and the Dhugarls (with which the Kran share their homeworld and a common ancestor) seem to follow the same general plan with an added dash of LittleBitBeastly.
** Biologist Amber Greene has some [[BreakingTheFourthWall strong words]] about her universe's apparent shortage of StarfishAliens.
* SacredFirstKiss: Shimauu got hers from [[spoiler:''Asagi'']]. She was not happy, to say the least.
* SaveTheVillain: When the JSDF soldiers attacking the Dai Kagurren surrender at the end of Season 3, Sergeant Greene rejects [[ObligatoryWarCrimeScene Ryougi's suggestion that they just execute them]] and instead orders them loaded up and transported to safety rather than leaving them exposed to radioactive fallout from the nuclear warhead they'd just detonated in the upper atmosphere.
* SecondActBreakup: Fuuka cheats on Mark with Koiwai, and they break up. Later that same day, they get back together.
* SecretProjectRefugeeFamily: The citizens who didn't get the privilege of being evacuated to Hawaii or another safe place grouped together and created the varied gangs that roam devastated Japan. Associated with the TrueCompanions trope here as well since this also applies to the united alliance of main characters, the alien Mark and his [[VideoGame/TeamFortress2 RED Team]] buddies, and the members of the Yotsuba Gang and Yanda Gang. Once again, one big happy family...
* SesquipedalianLoquaciousness: Most characters once played by Passerby suffered from this at times.
* SexSlave: [[BigBad The Boss]] was planning to turn Tardboy and Kagura into these, essentially forcing them to have sex on camera in order to sell more porn [=DVDs.=]
* ShipTease
* ShoutOut: To {{Achewood}}, [[Series/BattlestarGalacticaReimagined Battlestar Galactica]], {{Firefly}}, and far too many others to list.
* SiblingSenioritySquabble: A bit of a one-sided example with Tomo and Torako. Tomo is constantly reminding everyone that she is a full ''four minutes'' older than Torako, to compensate for the fact that her sister is otherwise taller, more mature, arguably smarter, and can easily trounce her in a fight. Torako just goes along with it, since she doesn't like being at the top of the totem pole anyway.
* SiblingYinYang: Again, Tomo and Torako Takino.
** Roberta and Amber Greene could also apply, as the former is usually very outgoing and friendly while the latter is shy, reserved, and would usually just rather be left alone.
* SickeninglySweethearts: Mark and Fuuka. Kagura and Sakaki can fall into this at times as well, and Tardboy tries to be this with Torako.
* SleepCute: Sasuke and Rei at one point in Season 3.5. Cue CutenessProximity-induced {{Squee}} from Elesia.
* SlidingScaleOfGenderInequality: Level 5; sometimes slides towards Level 6.
* SociopathicSoldier: Shimauu is nearly gunned down in an alley when she runs into a group of these.
* SoundEffectBleep: Despite the countless instances of creative, uncensored obscenities that occur in Yukari is Free, where no topic is seemingly barred (so long as the pictures used are Safe for Work), when Mark began describing things he's seriously considered doing in the past, it was so incredibly obscene that it warranted one of these.
** The ''uncensored'' bit deemed safe enough for human consumption is half a sentence that still contains the words "goddamn" and "fuck."
* StayingAlive: Barring zombiefication, Yukari has died about 4 times.
** Osaka [[spoiler:has died about twice so far. She was able to return after promising to save Chiyo-chan from her evil counterpart.]]
** [[VideoGame/{{Portal}} GLaDOS]] has been killed on-screen at least twice, but she claims to have been killed far more times than that.
** Chiyo is now a member of this club, [[spoiler:because her soul WAS housed inside a doll while her body was still possessed by The Profound Darkness/Shin Chiyo. She's better now]].
* {{Stealth Hi Bye}}: Asagi loves this trope.
* SuperheroesWearCapes: When suited up for combat, Mark wears a cape attached to his armor.
* TalkativeLoon: Kenji.
* TemptingFate: At one point in the second season, Tomo was scolded by Torako for declaring that they were perfectly safe and that nothing was going to happen, for precisely this reason. Moments later the military convoy transporting them to safety was attacked by furries and Nyamo was kidnapped.
* ThinkingOutLoud: Virtually all characters written by Passerby were guilty of this, but by far the biggest offenders were Kyoto and Moto.
* ThisIsForEmphasisBitch: "THE POWER OF CHRIST COMPELS YOU, BITCH!"
* TooDumbToLive: Most of the cast fall into this trope at some point or another. Surpisingly, most of them haven't kicked the can yet.
** Shimauu is a prime example, running away from the safety of a military base to wander aimlessly through a ruined city populated mainly by gangsters, thieves, murderers, and rapists. Alone. In the middle of the night. To find someone who, for all she knew, would just tell her to get lost. Great thinking kid, that couldn't ''possibly'' go wrong!
** Yui Morishita is apparently a very literal example, as she seems to just flat-out ''forget to eat'' for days at a time.
** Jumbo. Oh god, Jumbo. It's hard to decide what's stupider, handing an enemy your loaded gun or informing a PersonOfMassDestruction that his girlfriend is a "lesbian whore."
* TrademarkFavoriteFood: Don't eat anything Rachel makes, unless you ''really'' like mustard.
* TraumaInducedAmnesia: Rei Kakizaki suffers from this to a degree, in that she has suppressed many of her memories of the zombie apocalypse and can become extremely unpredictable and violent if something happens to make her remember.
** It has also been suggested in the discussion threads that Shimauu may be repressing memories of that period as well.
* TrueCompanions: Nearly everyone on the good guys' side is just one big family. A big, perverted, destructive, badass family that can barely go five minutes without fighting amongst themselves.
* {{Twin Threesome Fantasy}}: It's not just a fantasy for Yomi.
** [[spoiler:Nor for Tardboy, though he's not likely to get another chance at it.]]
* {{Twincest}}: Tomo and Torako, much to most of the cast's disgust, including, very recently, their father's.
* TurnCoat: [[spoiler:After learning that [[VideoGame/{{portal}} GLaDOS]] was going to betray her, Floaty switches sides and helps the group escape from the Enrichment Center.]]
* UnbrokenVigil: [[spoiler:Tomo stayed at Torako's bedside almost the entire time she was in a coma, only leaving to use the toilet or when she was forcibly removed. Though it ended up only being a couple days, she swore that she'd never leave even if Torako didn't wake up for thirty years.]]
* {{We Can Rebuild Him}}: Yukari does this to Kyoto and ''herself'' by possessing a factory
* WeirdnessMagnet: Lampshaded by Chihiro and Shimauu.
* WhatDoesSheSeeInHim: Virtually every relationship in Yukari is Free falls under this, possibly the only exception being Sakaki and Kagura's. Ena doesn't see what Fuuka sees in Mark, Miura initially protests Chihiro being with Sakakuro, Jumbo and Koiwai don't understand Yanda's desire for Asagi, Kagura wondered once why Chiyosuke would want Osaka, and some of the Yotsuba Gang Members wondered why Ryougi/Gang Member 122 had crushes on the strange, reclusive Ran (Gang Member 114), and the vulgar, abrasive Ai (Gang Member 37), just to name a few.
* WhatHappenedToMommy: At the start of the ZombieApocalypse Ran and Rei Kakizaki's mother became infected with the zombie virus, killed and partially devoured their father, and then attacked Ran, forcing Rei to [[ShootTheDog beat her brains in with a baseball bat to save her sister.]]
* WrenchWench: Yumi and Haru.
* {{Yandere}}: Chihiro, after hooking up with Sakakuro, before Season 3.5.
** Kaorin, and her trying to kill Kagura for "stealing Sakaki" from her. Enough said.
* ZombieApocalypse: Most of Season 2.
