Pretty Cure Transient School contains examples of:
A.I. Is a Crapshoot: The people who created Skynet had horrible foresight. Originally, Skynet was a machine created to absorb the stray negative energies leaking from the many Evil Pocket-Universes scattered about the Pre Cure-verse. The creators of Skynet obviously never even suspected the possibility that absorbing so much negative thought-energy might cause Skynet to develop emotions, and for those emotions to be nothing but hate and rage for anything and everything in the multiverse, leading him to become an autonomous factory with the one goal of eliminating every Pocket Dimension in existence (to say nothing of how naming a computer "Skynet" smacks of Tempting Fate). But lo and behold, that is exactly what happened.
It becomes a sort of Fridge Horror, when you consider that all those worlds made up of negative emotions were being kept in check by Skynet. After he strayed from his initial cause, nothing was left to get rid of the negative energy seeping out of the "Evil" dimensions. Ever wonder why the author's fanseries are so dark? That's right, the only thing that was keeping the world of Pretty Cure happy and bright was Skynet. Suddenly the Sugar Bowl doesn't seem so sweet when it got that way because of a soon-to-be-omnicidal AI.
And That's Terrible: Lillian paraphrases the Trope Namer while discussing Chopper's recent crime spree in episode 26 (appropriately, she's slated to play the lead in the Superman musical in that very episode).
Lillian: And when no one was looking... Char Chopper took 40 cakes. Ashley: I don't get it. Lillian: He took 40 cakes, that's as many as four tens! And That's Terrible.
Anti-Hero: Lillian's father was Type II during the Video Nasty crisis; he and several of his schoolmates played devil-may-care and lifted several copies of each of the 72 Video Nasties from local video stores in Oxford between 1982 and 1985.
Armor-Piercing Question: After mocking Takashi for a bit in Episode 30, Johan confronts him with a single question: "Shouldn't a boy be eager to become a man?" In one line, Johan lambasts Takashi for growing to enjoy wearing girl's clothing, mocks his attempt at reconciling his masculine self-image, and forces Takashi to realize just how much he's fallen short of his image of ideal "manliness." Sasami shows up and yells, "URUSAI, YOU BASTARD! URUSAI! URUSAI!!!" as she whacks Johan, then she Bright Slaps Takashi for doubting himself and reminds him that he shouldn't let Johan's mockery keep him down like that and that he should be satisfied with who he is at the moment. Takashi resolves himself to ensure that Johan's words won't bring his spirits down that easy, and he transforms into Cure Mako just as his upgrade arrives.
Arson, Murder, and Jaywalking: Johan is arrested several times throughout the series on charges of "gender discrimination, attempted assault, and hypocrisy". The first charge is for the obvious; the second charge is for his scuffles with the Cures (it doesn't help that there are several witnesses to each fight that ends with his arrest); and the third charge isn't so much for hypocrisy in general as for badmouthing crossdressers while himself in drag. To Yamabara, that's a special kind of hypocrisy, and not in a good way.
Episode 33 adds a one-off charge of "10 counts exposing illegal drugs to a minor" due to the allegations that Johan had unleashed an illegal hallucinogen into the backstage area and intoxicated 10 unknowing students.
Badass: Takashi, who in the Festival OVA goes through an entire basketball game wearing a maid dress. Justified, as he had just come to the game straight from his homeroom, which was doing a Maid Cafe (the girls simply wore frilly aprons over black gakuran).
Takashi: I just wish the skirt was shorter, though. You know, so it wouldn't impede my running too much.
Bilingual Bonus: Lillian tells Ashley in episode 3, "You should check out the TV systems here in Yamabara: the video's quite coy!" Ashley replies, "I don't know what you're talking about." Those unfamiliar with Japanese and British video systems would assume Lillian called Japanese video strong (or koi) or gentle (coy). Take a deeper look into both NTSC and the Japanese language, though, and you'll understand that Lillian was actually saying that the video system in Yamabara is Never The Same Colour (or Kesshite Onaji-Iro).
Cardboard Prison: No matter how often the Cures actually have Johan arrested (most notably in episode 30 on charges of gender discrimination, attempted assault, and hypocrisy), he always escapes. His Joker Immunity wears off near the end of the series, though.
Lillian: I suppose I speak for Principal Yoshi, Ashley, and the other students and staff of Sakurazaki, Shiraishi, when I say "See you next Tuesday!" [flips off Shiraishi] Principal Yoshikazu: Truer words were never spoken about the feminazi we're dealing with.
Earlier, an enraged Principal Yoshi, upon hearing how poorly Principal Shiraishi treated her male students, calls Lillian over to her with an unusually sharp tone of voice, then whispers into her ear exactly what she wants her to tell Shiraishi. Lillian repeats those exact words to Shiraishi (as noted above) during the confrontation.
Principal Yoshikazu: I am gonna throttle that bitch. Lillian! Front and center! NOW! [Lillian walks up to Principal Yoshi] Principal Yoshikazu: Now, when we confront Shiraishi in her office, here's what I want you to say—and don't forget this, it's an easy one. [Principal Yoshi whispers in Lillian's ear; her eyes widen in shock] Lillian: Really? You want me to say that? Principal Yoshikazu: Put simply, its acronym is probably the kindest possible word to describe such a person as Shiraishi.
Cross Over: With Club Pretty Cure, where the characters are portrayed by live actors (including two of the English dubbers). The Japanese seiyuu all reprise their roles.
Culture Police: UMBRELLA has shades of this; they are at war with a world known as Trapland, which presumably has reversed gender roles from our world (never mind that they weren't responsible for Yamabara outlawing gender discrimination in the first place). Not to mention, at least one of the organization's members has openly disapproved of crossdressing (and gets arrested for it, this being Yamabara he's dealing with, in several of his appearances, only to break out each time).
Deadly Game: Takashi is forced into a very lethal board game against Chopper in episode 36 (in a Shout-Out to Deadly Games, not to be confused with the UPN sci-fi series, Chopper is wearing a thick black glove on his dice-rolling hand), with not only his life but also his friends' lives at stake. In a form of torture that Johan would enjoy, Takashi is wearing his school uniform throughout.
Due to the Dead: The Minami family has its own funeral ceremonies for its deceased; deceased Minami family members are given a graveside service at the cemetery near the Minami mansion: in a blend of Western and Japanese traditions, a Japanese wake is held at the gravesite with the casket bearing the body placed on a raised platform above the grave; a switch on the metal rectangular ring is thrown immediately following the wake, and the casket slowly sinks into the ground. Such a funeral is shown in episode 31 when Sasami's younger cousin dies of a chronic illness.
Early-Bird Cameo: Several of the Cures appear before their introductory episodes.
Earn Your Happy Ending: The corrupt Straw Feminist administration of Hirano Junior High is overthrown with the help of Sakurazaki's students and staff and replaced with moderates who think like Sakurazaki's own principal: put your students in drag, but don't favor the female sex over the other; rather, let equality reign among both sexes.
Engineered Public Confession: How Principal Yoshi takes down Shiraishi in the OVA (specifically, Principal Yoshi recorded Shiraishi ranting about the female race being dominant and flat-out saying that unlike Principal Yoshi, she doesn't give one shit about Yamabara City Council Ordinance 11-38). One of the rare times in a Precure fanseries where the villain is taken down without a single punch thrown.
Every Proper Lady Should Curtsy: Shiro and Ashley both do this a lot. Sasami and Lillian both do this a few times as well despite neither of them ever wearing a skirt! Also, Takashi does a rather, um, mocking curtsy directed at Johan in episode 30 right after gaining the courage to stand up to him.
Evil Counterpart: The administration of Hirano Junior High, which unlike that of Sakurazaki is hellbent on complete reversal of gender roles in addition to gender uniforms.
Principal Shiraishi: You're too weak to understand that only the female sex should rule supreme! I just took your idea and added quite a bit of my own into it! Principal Yoshikazu: And you call that inspiration? Don't make me laugh!
From Bad to Worse: Don't worry guys, Hirano is just a school with a slightly skewed take on equal rights. Oh wait, no it's not, it's an unfair school with rules that are sexist against men. Oh wait, no it's not, it's a crazy school run by a Straw Feminist who wants to feminize and subjugate all men. Oh, wait, no it's not, it's a monstrous school run by a sadistic dogmatic feminazi who has already feminized and subjugated the male student body of her school, using horrific physical and psychological abuse.
Gender-Blender Name: Played straight with Ashley and parodied with the mascots, both named Yuri (the gag is more obvious in the English version, where the male Yuri is a Fake Russian).
Gratuitous Catalan: In one of the Christmas episodes, Lillian sings "A vint-i-cinc de Desembre (Fum Fum Fum)" with no accompaniment whatsoever save for an acoustic guitar (played by herself), having memorized the lyrics with the help of an English-Catalan dictionary. The closing theme of that episode is a Japanese translation, called "Juunigatsu no ni juu go (Fun fun fun)", performed by the Cures.
Growing Up Sucks: Takashi eventually gains this opinion halfway through the series when confronted with the idea of puberty taking away his girlish appearance, a major change from his introductory episode where he grudgingly accepts having to wear a skirt. He's quickly made by Sasami to realize that neither puberty, Johan, nor Ted Turner's crayons should make him feel insecure about his future and that he shouldn't have to make himself believe that growing up will change his current viewpoints on his ability to crossdress.
Hypocrite: Johan voices his disgust for crossdressers on several occasions, saying in one instance "A boy who wears a skirt is an insult to masculinity." This is despite the fact that he himself wears stage makeup, is incredibly bishounen, and is by comparison one of the more camp villains of the series (even regularly crossdressing himself, egregiously enough).
I Did What I Had to Do: Lillian's father could claim this when he came his closest to getting arrested for shoplifting when he was younger. In his words: "Is it still stealing if it's already contraband?" He also claimed to have done it in the name of freedom of expression. The authorities wisely dropped the matter and turned their entire focus to confiscating leftovers after his gang completed each theft.
In-Series Nickname: Marius Newell's gang from the '80s is forever known to Oxfordian videophiles as the "Heroes of the Video Nasty Crisis" for their daring vigilante activity around video stores involving theft of the Nasties.
Japanese Ranguage: Emma Watson sometimes lapses into this when transitioning from Japanese to English in the Japanese version as the voice of Lillian.
Karma Houdini: Lillian's father and his schoolmates were never caught for stealing Video Nasties from stores; once the authorities stepped in to confiscate what was left, the storekeepers could do nothing about the thefts of those tapes, fearing that if they went after the thieves they might get in more legal trouble than the tapes already confiscated got them in. The stolen tapes themselves were distributed by the gang among those that wanted a copy, with Lillian's father keeping a small percentage consisting of one copy each of the Video Nasties. The one time the authorities tried to arrest those responsible, Lillian's father claimed to promote freedom of expression among home video (his campaign would ultimately fail for the most part, with restrictions only eased toward the end of the 20th century and the start of the 21st century) and that since the tapes would be contraband anyway, it really can't be called stealing. The authorities listened to this Insane Troll Logic, and the boys quickly mellowed as the Video Nasty crisis came to a close, vowing to never again steal from a video store.
Kill It with Fire: Skynet ultimately tries to do this to the Cures by leaving them to die in a garbage dump incinerator.
Larynx Dissonance: Played for Laughs in the Very Special Episode, where Takashi mentions his basketball teammate's voice was already around the tenor range anyway before puberty; this references how nearly half the male first years at Sakurazaki (including Takashi and Ashley) are voiced by adult males. Interestingly, in Ashley's case Satoshi Hino uses his "cutesy" voice from the "Melon Pan Dance" video from Shana Tan as the voice of Ashley in the Japanese version; however, Rupert Grint uses his own voice as Ashley in the English version.
Trapland takes this Up to Eleven. The secondary sex characteristics are completely reversed; it's the men who have breasts, not the women. The boys are small, curvy, and ridiculously feminine, while the girls are all tall, well-built, and quite handsome. To top it all off, the entire place is a Fisher Kingdom that enhances the femininity of boys and the masculinity of girls. During the Cures' brief visit, even Takashi struggles to keep himself from acting like a giddy schoolgirl, and Ashley, Hiro, and Jiro are affected so badly that they weren't even aware of the changes to their behavior. Shiro, however, remains unchanged, and even says that he feels right at home.
Manly!Lillian: Okay, I'll bite; what do I have to do to keep him like this?
Among the pairings in this category are Ashley/Lillian and Shiro/Chihiro.
Meganekko: Shiro, one of the boys on the team and the Sensitive Guy to Ashley's Manly Man. Ashley himself wears glasses with the fairy ballerina costume he's asked to wear while he and Lillian watch Shiro's performance in the dress rehearsal and recital.
Meido: The Festival OVA has Ashley and Lillian participating in their homeroom's Maid Cafe. The girls' maid outfits are, predictably, more masculine yet equally frilly versions of the boys' maid outfits (while both sexes wear the same white frilly apron, the girls wear black gakuran, and the boys wear the usual maid dresses).
Misaimed Administration: In one OVA, a school from a neighboring city decides to adopt Sakurazaki's inverted dress code. Unfortunately, the school in question is run by an administration full of Straw Feminists, and the only reason they adopt the dress code is because they want to "pacify" the male students as part of their 'quest' to make women the dominant sex. This comes off as an in-universe Wall Banger to Sakurazaki's principal.
Principal Yoshikazu: ...And this is part of their School Charter. Really?
When Takashi infiltrates a bio lab being used by the villains to create the zombie virus so he can destroy as many strains of the virus as he can, taking one with him so he can give it to a bunch of honest scientists so they can do some research with the hope of making an effective antidote;
When Sasami retrieves a tape-recorded broadcast of a news segment from Night of the Living Dead that would help counter the zombies in the event that Sakurazaki's attempts to stop the zombies from taking over ever fails for any reason;
When Ashley tries to stop the Big Bad at the climax; this time, Ashley is held up by a magnet, and he's nearly chopped up by a turbine fan below (complete with a subversion of the Gory Discretion Shot) when he attempts this trope in such a manner.
Moral Guardians: In-universe, some parents have complained about Sakurazaki's uniform policy, but they always drop their complaints as the students get used to it. This year is no exception. Nowadays, whenever a boy or girl in the opposite gender's uniform (specifically, a blue Sailor Fuku or a pink masculine parochial uniform) is seen in public (which happens more often to girls than to boys), it's an Unusually Uninteresting Sight.
Nose Bleed: Sasami in a later episode. Lillian also gets one when Ashley accidentally flashes her in episode 18.
No Swastikas: When the announcer names the costumes the basketball team is wearing in the Festival OVA, he's careful to mention the cabaret dancer costume as being from "'30s Germany" instead of "Nazi Germany".
N-Word Privileges: Principal Yoshi uses this trope to counter an over-the-phone accusation of degradation by Shiraishi, who is awaiting arraignment, for having one of the Sakurazaki girls drop a stealthC-bomb to her face in an audio recording. At this, Shiraishi's lawyer, who came to visit her, advises her to plead guilty to violation of Yamabara City Council Ordinance 11-38 and thus spare herself further humiliation in that manner.
Painted-On Pants: The black leggings Lillian wears when she and Ashley (who's dressed as a fairy ballerina from the recital) watch the dress rehearsal for and actual performance of Shiro's ballet recital.
Panty Shot: If any Cure's going to get these it's definitely going to be Cure Bridget. None of the Cures wear a Magic Skirt; the girls wear shorts, and the boys wear either leotards or Modesty Shorts, but whenever Cure Bridget's skirt flips his panties can be seen.
Pimped-Out Dress: Ashley wears a red satin Georgian dress to the school dance. He also cosplays as Orihime Soletta for formal occasions such as the school's Yule Ball.
Pink Girl, Blue Boy: As mentioned earlier, the colors of the Sakurazaki uniforms. An example of a two-person pairing like this is Sasami and Takashi.
Playboy Bunny: One of the basketball team's boys in the Festival OVA; the announcer refers to him as "a bunny in a leotard" when introducing the basketball team for Sakurazaki's exhibition basketball game during the festival.
Poor Communication Kills: Averted; the school always explains to parents that the reason why their kids are being forced to crossdress is to give them a better respect and understanding for the opposite sex just so any potentially complaining parent will drop their complaints, and amazingly, most do so immediately. Those that don't are reminded of Yamabara City Council Ordinance 11-38, prohibiting gender discrimination in every field (clothes included) on pain of up to 2 years in prison and/or a million yen fine, just to shut them up.
In episode 1, after Takashi accidentally clocks her face with a hard-served volleyball during PE, Sasami says, "Takashi, you son of a bitch."
In episode 5, Takashi is signing up with the basketball club. Lillian tells him, "You're signing up to shoot some balls through those hoops. I know you've got the balls for it, so good luck!"
In episode 15, in response to learning of the finals, Takashi says, "Oh, shit."
In episode 21, we get this frank conversation involving Lillian and Sasami:
Sasami: Tell me something, Lily. Lillian: What is it? Sasami: What is a five-letter word for a four-letter word? [Beat] Lillian: ...Bitch.
In episode 22, when a "zombified" Lillian approaches him, Takashi yells, "OH SHIT! NOT YOU TOO!"
In episode 30, Takashi is angsting over his coming puberty and Johan's taunting him. After some encouraging words from Sasami, Takashi yells, "JOHAN! I'VE HAD ENOUGH OF YOU! COME ON OUT AND FACE ME, YOU ASSHOLE!"
In episode 33, Lillian, upon hearing Ashley's story, says, "What a prick this Johan is!"
In episode 36, Takashi is losing to Chopper in the board game. His health at a low point, he says, "I haven't given up yet, shithead... and I never will, since my friends are at stake!"
In episode 37, Ashley says "Oh, shit" when he realizes that the only way the black side will win the chess game is if he moves his piece to H3 (and exposing himself to the white Queen, who subsequently knocks him out of the game), thus clearing the way for Takashi to put the white King in checkmate.
In episode 45, Lillian says of her father, "Back in the early '80s, my dad was a scoundrel, a devil-may-care son of a bitch who committed civil disobedience throughout the Video Nasty crisis in the name of freedom of expression."
In episode 52, when Cure Haruhi realizes that Skynet wasn't really going to save the Cures after all, she panics and yells, "WHAT!? OH, SHIT!"
The OVA has several uses of the word "bitch" scattered throughout, including a few from Lillian and at least one from Principal Yoshikazu. Lillian also drops an F bomb after encountering the boy who tells his story to Principal Yoshi.
Lillian: Holy fuck, this is getting much worse all the bloody time!
Public Domain Soundtrack: The theme from Zombi can be heard in episodes 21 and 22 rather pervasively; as the episodes, particularly 22, involve a "zombie outbreak" at the Minami mansion, this is actually quite fitting.
Sensitive Guy and Manly Man: Shiro and Ashley. Ironically, if their respective namesakes ever did a crossover, Hideyoshi would be the Manly Man out of the two, as Jun actually wears a female uniform as his school uniform. Interestingly, Ashley himself is the Sensitive Guy to Takashi's Manly Man.
Shana Clone: Sasami, complete with the obligatory "Urusai! Urusai! Urusai!!!"
Shout-Out: Similar to episode 6 of Shugo Chara!, Ashley wears a fairy ballerina costume at the request of ballet student Toshiki's mother while watching Shiro perform as Toshiki's understudy for the monthly recital in one episode after Toshiki injures himself shortly before the big performance; to Ashley's relief, all he has to do is sit back and watch as his friend performs. Like Amu from the source material, Ashley clearly didn't "feel comfortable in the bloody outfit".
The ice dance performed by Lillian and Ashley at the start of episode 43 is a recreation of Big Bird's ice dance at the start of Christmas Eve on Sesame Street.
The climax of episode 52 ends with the Cures being saved from a fiery end at the garbage dump incinerator, just like how Toy Story 3 ended.
Shown Their Work: It's stated in episode 31 that most Japanese cemeteries are so small that 99% of the time, ashes are buried instead of bodies. It's also explained that the Minami family has its own cemetery (and not just a family grave), and due to how much room they have on their land it's big enough for dead bodies to go six feet under, which is why their deceased receive Western graveside services that resemble Japanese wakes (see Due to the Dead above).
Skirt over Slacks: Done by a few minor characters, usually male, though in episode 31 Akari Minami is interred wearing a short black dress over black leggings. Takashi also does this a few times to please his sister and also wears a green skirt over gray leggings in the 3-D Movie.
Sound Effect Bleep: Just when you think Shiraishi's going to yell the C word very clearly, the white noise volume spikes unexpectedly.
Shiraishi: Am I correct in assuming that one of your girls implicitly called me a— [Principal Yoshikazu winces as white noise covers up the offending word rather loudly] Principal Yoshikazu: Yes, she did. And she was right to do so. And don't give me any of that crap about degradation; her gender gives her C word privileges, be they implicit or explicit.
Straw Feminist: The Hirano Junior High administration. Sakurazaki is offended at how the school's legacy is being tarnished by another school.
Ashley: I don't normally speak ill of women, but there's a bunch of them that are acting real contemptible at the moment, them being feminazis and all. Lillian: They're right bitches, they are! We're going to have to do something about it! Principal Yoshikazu: Them's fighting words, Miss Newell! A call to arms for all of us at Sakurazaki! [activates PA] If this administration at Hirano is going to corrupt our legacy, we are not just going to stand around and watch! I hereby call an emergency Great Hall meeting this minute! All students report to the Great Hall; I have some serious words for you people involving taking down those freaks of nature at Hirano! [deactivates PA] Let's go.
Surprisingly Good English: Lillian can speak perfect BBC English; no surprise, as Emma Watson supplies her voice in the Japanese version (thus playing the inverse of this trope) as well as her native English version. Of course, while she still speaks Japanese in the English dub, it's less frequent, but it's still there, especially when she's teaching Ashely the basics of Japanese in early episodes.
Also Satoshi Hino as the Japanese voice of Ashley. This is especially useful in early episodes, as Ashley is still learning Japanese. He even uses BBC English!
Think of the Censors: Despite her status as an open Yaoi Fangirl, Sakurazaki's principal wishes her students to not engage in immoral behavior (although the school's uniforms basically force each student to crossdress; then again, the colors on each uniform reflect their genders).
Tights With A Skirt: Enforced and then gender-inverted at Sakurazaki Junior High. Also worn by two male Cures. Oh, and Shiro tends to do this a lot, while Ashley is an infrequent employer of this trope, including when he wears a tutu over pink tights as part of his casualwear in The Movie (he does admit to wearing that one to try his hand at Hollywood-style fashion).
Values Dissonance: Sakurazaki Junior High is an...interesting case. While there are laws in place that prohibit gender discrimination, when the school was established in 2002 its board apparently thought that the best way to encourage gender equality was to reverse the dress code. And despite the acceptance of crossdressing, there still seems to be a minor stigma against homosexuality.
It's invoked again in the OVA, where Sakurazaki becomes aware of a neighboring school that copies their dress code to advance a Faux-Feminist agenda. The "Feminazis" simply come off as obnoxious blowhards, and at first they are not considered that big a deal. AtFirst.
Very Special Episode: Episode 30 deals with the subject of puberty and Takashi's anxiety about it happening to him sooner or later. His confidence shatters completely when Johan mocks him for crossdressing; however, Sasami manages to reverse that and renew Takashi's spirits enough to take Johan on.
Principal Yoshikazu: Never trust a computer with the name Skynet, OK? I saw the movies, and I can tell you Cyberdyne obviously didn't see the bad luck in calling a computer, let alone a supercomputer, Skynet. Cure Mako: Ha! I knew it all along! I saw the movies too and can safely tell the rest of you boys and girls, "I told you so!" [Cure Mako does that akanbe thing] Cure Haruhi: If you ask me, calling a computer "Skynet" is just like calling your luxury liner "Titanic". I gotta ask: what the bloody hell were those programmers thinking!?
Yaoi Fangirl: The principal of Sakurazaki Junior High makes no secret that she's one which in part explains the uniforms (other parts of the explanation include "So our students can gain a better respect and understanding of the opposite sex" and the fact that Yamabara city law legally prohibits gender discrimination in every area, including clothing). Then again, at least she doesn't encourage homosexuality among her students too much (although a total ban on same-sex relationships would probably be in violation of anyone's civil rights in today's society), and while there are a few same-sex couples among her students, she has gone on record as stating how her students should mind other decency standards since all of them are required to crossdress during school hours as it is.
Zettai Ryouiki: Sasami wears Grade S with a bunch of her casual outfits and her Cure costume. Always paired with short shorts.
