->''"New science teacher, Machiko Mai, is a young and attractive woman with healthy mind and body. Being around her makes everyone happy. Students like to play practical jokes on her, but no matter how many times they cause troubles, she does not get upset. She always tries hard to understand her students."''
-->-- Studio Pierrot's description of the series

''Maicchingu Machiko Sensei'' is a series that could be best described as a loose compilation of {{Fanservice}} or {{Ecchi}}, starring a female schoolteacher and her pervy students. It aired in TheEighties in Japan as a [[GettingCrapPastTheRadar kids']] [[ParentService show]]. It had a lot of controversy with the MoralGuardians but somehow managed to survive.

Machiko Mai, a young and inexperienced teacher, is taking her first job as a teacher to a group of elementary students. Unfortunately (for her), Machiko's students, lead by resident troublemaker Kenta, think it's utterly hilarious to grope her, flip her skirt, or find new and exciting ways to get rid of her clothing. Even worse, the very universe itself seems to think it's funny too; despite her best efforts, almost every adventure ends up with her at least slightly humiliated (ie: stripped to her bare ''pantsu'' if not completely naked).

Add a cast of ninnies and perverts, a standard children's show plot, and you have one of the most infamous {{ecchi}} series in history.

It is finally getting an English release, 30 years after the manga started, courtesy of [[http://rgfansub.wordpress.com/2010/10/20/maicchingu-machiko-sensei-1-an/ Anime-RG]].

!!Tropes in the series include:

* ACupAngst: Tenko. In a episode, she discover to be the more flat-chested of the group and not like this. How? A {{chikan}} ignoring her preferring to harass her friends.
* AbhorrentAdmirer: Maruko for Kenta.
* TheAce: Machiko is not just a teacher. She can act, dance, sing, fight, swim, pick up any random skill on a dime and is otherwise perfect aside from her inability to keep dressed.
* ActionGirl: Despite being a victim of a ''lot'' of pranks, Machiko often gives back as much as she takes. She's more athletic than the rest of the staff (including the phys ed teachers), able to pick up skills like skateboarding in one or two tries, and knows martial arts of some kind -- several episodes involve her beating the crap out of someone who goes too far.
* AllClothUnravels: One gratuitous example was an episode in which no fanservice was provided until the last thirty seconds or so of the episode... where she goes ice-skating, her student pulls a thread and slides her across the ice, revealing her breasts.
* AllAnimeIsNaughtyTentacles: Animals seem to be pervs in general. One particular octopus had a very good grip on her swimsuit top...
* AllMenArePerverts: The entire school seems to be perverted.
* BarbieDollAnatomy: Averted; see NippleAndDimed below. The "Box" mangas went even farther, with Machiko's naughy bits being non-explicitly visible a few times.
* BathingBeauty: Almost every episode has Machiko in the bath or at least the shower.
* BathtubScene: Many episodes include a scene with Machiko in the bath tub. One scene involved Kenta attempting to join her.
* BeachEpisode: Few of these. One of which even took place in Hawaii.
* BeautyContest: Machiko entered in a few of these. There was one episode in which she lost, which is surprising since everyone was in love with her.
* BecauseDestinySaysSo: It does not matter how, it does not matter where, it does not matter when -- somehow, someway, Machiko ''will'' lose her clothing, usually in the most humiliating way possible.
* BigBallOfViolence: One episode ends with all the characters getting into a fight with this effect. And, of course, [[OnceAnEpisode Machiko loses her top in the melee]].
* BodyPaint: A couple of instances of this in the manga. PlayedForLaughs, of course. It would have [[CompletelyMissingThePoint helped]] if Kenta's plan hadn't involved ''painting Machiko solid [[BlackFace black]]'' (instead of, say, trying to paint clothing or somesuch).
* ButtMonkey: Yamagata-sensei. He's head over heels in love with Machiko, but he's also a bit of a hornball and not above joining in with Kenta's schemes, only for them to backfire on Yamagata-sensei, spectacularly. He remains sympathetic because every so often, his schemes involve ''proposing''.
* CatchPhrase: "Maichchingu" ("Shame!"). Something she says after something happens to make her lose an article of clothing, get groped, or have her skirt flipped up. Which happens OnceAnEpisode (at least).
* CensorSteam: Completely averted, as in [[ValuesDissonance most shows of the era.]] ''Kids' show!''
* TheChewToy: Michiko, obviously! Everyone, including the universe itself, enjoys sexually harassing her and it's all for the viewer's amusement.
* TheChikan: An episode feauture a man harrass the young female student on a bus. Initially Kenta is mistaken for the culprit, but Machiko and Kenta set a trap for catching the real culprit.
** {{Hypocrisy}}: Considering what Kenta does every day, you do not understand how he is different from the molester except for the age.
* ChildrenAreInnocent: [[AvertedTrope They really, really aren't.]] Some of them aren't up to speed on the {{ecchi}} parts of her situations, but all of her students at least think it's ''[[NakedPeopleAreFunny funny]].''
* ChivalrousPervert: Kenta and Fukuoka-sensei. Special note goes to Fukuoka-sensei, who is ''teaching elementary students nude figuring drawing.''
--> '''Fukuoka:''' A female in the nude is the apogee of beauty.
* CircusEpisode: An episode feature Machiko takes part in a circus. Tamako, the vice principal is worried. The reason for this is because Machiko is performing in front of a large audience [[GenreSavvy which means that she will end up with her clothes torn off]]. Her warnings fall on deaf ears. Sure enough, a tiger happens to get lose and tear Machiko's costume off.
* ClothingDamage: Machiko apparently wears clothes made of paper since they get ripped off very easily.
* DefeatByModesty: Kenta's favorite move while wrestling women (two are school matches and one is a professional event). He does it to Machiko once. Later, he wrestles a blonde wrestler who doesn't seem to care much, averting this trope. In another episode, an American foreign student comes to school. He tries it on her and while it makes her angry, she takes the time to beat him up before covering herself.
* DirtyKid: All of the boys fit this trope but particularly Kenta, who is often the ring leader of the boys and works out several plots to grope, disrobe, or otherwise act pervy to the eponymous Miss Machiko (or their female classmates).
* DoggedNiceGuy: Yamagata-sensei, who frequently ends up getting mixed up with the student's plans, and CannotSpitItOut about his attraction towards Machiko.
** Hiromi, who has a crush on the more serious student of the class but is often [[ObliviousToLove ignored by him]].
* {{Ecchi}}: One of the first TV Ecchi series. Relatively tame by today's standards, it still manages to do some things that would simply not fly on Japanese TV today -- like showing animated nipples[[note]](Although it could be said the censoring isn't for any particularly moral reasons, but to create DVDBonusContent.)[[/note]]. ''In the opening credits.'' ''Anime/{{Doraemon}}'', which was shown around the same era, was the same way (kids' show, mild {{Fanservice}} -- and infamously, the rename added CensorSteam, amongst other things.
* {{Fanservice}}: If you took out all of the fanservice, there would be very little of the series left.
** Although in some episodes, the fanservice honestly comes completely out of nowhere. For instance, at the end of one episode, a student [[AllClothUnravels pulls a thread on her sweater]] and exposes her in a skating rink, all within the last 15 seconds of the show. It was a typical cartoon up until that last moment.
*** Said sweater gag was used in the first live action movie -- Machiko's crochet-like sweater gets a single thread snagged while at home, and by the time she makes the full run to her classroom, her shirt is gone.
* FanserviceExtra: Provided, in the anime, by some random women or schoolgirls.
* FatGirl: Maruko. Reason why, sometimes, is ignored by pranks's Kenta.
* {{Flanderization}}: Machiko, particularly in the manga, ''particularly'' in the "Box" series of bonus comics the author released. Machiko goes from being a somewhat naive, good natured young teacher who accidentally gets stripped and groped a lot to being easy to talk into stripping ''herself'', and who often [[InnocentFanserviceGirl doesn't even notice anything's wrong unless someone points it out to her,]] (and even then, she is more bemused than anything else).
* FreezeFrameBonus: One Website/YouTube user noticed that while a guy was trying to pull a perverted octopus off of Machicko, you could see detailed nipples (Well MORE detailed nipples considering the series had no qualms with them) when the swimsuit was almost completely off. [[GettingCrapPastTheRadar Kids' show!]]
* FunbagAirbag: Happened in the first episode when Kenta and friends steal the eponymous character's panties and try to run away, only for her to head them off around a corner.
* FuroScene: The series has a few episodes with these scenes. Expect one or more male students (or even a teacher) to sneak a peek. One episode had a teacher and student flying in a kite and landing in a furo by accident. Of course, the eponymous Miss Machiko and her students were there at the time and the men (mostly) hid themselves.
* GagBoobs: One memorable instance of this involved Machiko breasts popping free from her shirt from a thief who had taken her as a hostage, which she used as a the start of a breast-and-karate-chop combo.
* GardenHoseSquirtSurprise: Used in the very first episode.
* GenkiGirl: Machiko-sensei. Her reactions to Kenta's pranks? A {{moe}} pose, her catch phrase, and moving on.
* GettingCrapPastTheRadar: It's a ''kids' show'' about a bunch of 8 year olds sexually harassing their teacher, who can't keep her clothes on for more than an hour or two at a time.
* GroinAttack: In episode 8, after using a Frisbee that's attracted to women's underwear on the girls all day, Machiko gets a hold of one that manages to fly toward's Kenta's underwear. Not lightly, it would seem.
* HandOrObjectUnderwear: Used repeatedly, although as a rule her breasts and bottom are fair game to be shown.
* HotForTeacher: Machiko. ''Everyone'' is attracted to her at least a little bit, which is why ''no one'' stops her students' games. That, and the very universe conspires to leave her denuded, so any such efforts would be futile.
* HotTeacher: Machiko of course.
* HypnoFool: Episode 10 involves Machiko going under hypnosis for some reason or other. Kenta attempts to mess with her, only to leave her with a mental GenderBender. She then goes to the men's room and ''uses the urinal.''
** Similarly, one of Manga!Kenta's favorite tricks is to convince a just-woken up Machiko, whom he has almost inevitably stripped while she was asleep that she was going to go do something she previously refused to do. Examples from the manga include teaching class in the school pool, wearing a NakedApron to her class's cultural festival MaidCafe, or tormenting Yamagata-sensei in some way.
* IdenticalStranger: An episode feature a woman identical to Machiko. The only difference is that she is red-haired and Machiko is a brunette.
* KarmaHoudini: The students rarely get punished for groping, flipping skirts, and undressing women (it's not always Machiko).
* LaserGuidedKarma: In some episodes, Kenta and his friends get stripped by the female students, sometimes with Machiko herself helping out. In one episode, Machiko had Kenta's mother called after Kenta took pictures of her in the bath. His mother stripped him down and spanked him in front of an audience, which was PlayedForLaughs. And yes, no one bats an eye to that either so at least there's no DoubleStandard.
* LongRunners: Would you believe the premise described above lasted for 95 weekly episodes across 2 ''years''? The now out of print DVD boxed set will set you back at least 70,000 yen, usually closer to 100,000 ($1000 USD) -- which is only slightly more expensive than when it was ''in print.''
* MaleGaze: The camera often focuses on Machiko's curvaceous body.
* MarilynManeuver: Her students often put fans on the ground and other elaborate ways of getting her skirt up. There's also her somewhat unique "Maicchingu" pose, which is a Japanese anime trope in an of itself.
** Female students are not immune also and join in the pose.
* MegatonPunch: What happens when Yamagata-sensei happens upon Machiko at the exact wrong moment. Like, say, after she's woken up, but before she realized that Kenta has stripped her, ''again.''
* ModestyTowel: Subverted, as if she ever dons one it usually falls off.
* MsFanservice: To her students. And the viewers. Perhaps the most well known and UrExample in Anime.
* NakedFreakout: Considering that Machiko OncePerEpisode ends up naked, it has featured many subsequent freak outs. Although as Machiko is a [[GenkiGirl Genki]] PluckyGirl, her freakouts tend to be a cute pose, her saying [[CatchPhrase "maicchingu!"]] ("Oh, how embarrassing!"), and either smiling or [[MegatonPunch beating the everloving crap out of someone]].
* NakedPeopleAreFunny: A major point of the series. Be it slightly erotic fanservice or not, Machiko losing her clothing is ''hilarious.'' (And ''very'' {{moe}}.)
** The manga's first chapter is very similar to the first episode of the anime, except instead of biking across town in her underwear, Kenta tricks Machiko up a flagpole while only wearing a towel... and then steals said towel to use as a parachute.
* NippleAndDimed: Machiko's nipples are openly visible, even in the ''opening''. How the hell was this aired as a kids' show again?
* TheNudifier: Kenta often comes up with very elaborate schemes to get Machicko's clothes off, which often reach near RubeGoldbergDevice levels of absurdity -- and always work.
* OncePerEpisode: Either she will lose her clothing (usually her shirt), her skirt will get flipped or ripped off, or she'll be groped, usually by Kenta. Or any combination of the above.
* OnlySaneWoman: Tamako, the vice principal.
* PantyShot: OncePerEpisode. At least. And not limited to Machiko.
* ParentService: Ooooh boy. The major reason it wasn't killed off. The demographics on the series viewership were absurdly skewed.
* PlayboyBunny: Machiko is shown in a bunny suit during the closing credits among other outfits. It says something when this series is so chock-full of fanservice that they had to cram a playboy bunny suit in during the credits for little reason.
* ProWrestlingEpisode: This series had a few episodes centering around either pro wrestling, school-centered Olympic wrestling, or sumo wrestling.
* PublicExposure:
** One episode showed the school art teacher painting Machiko. It's believed that he is painting her nude at first but we later find out that she was clothed for the session.
** Another episode had a pervy male teacher make a nude sculpture of Machiko, although she didn't pose for it.
** In yet another episode, her own students needed to raise money and talked her into stripping down to her underwear to take photos and send them into a magazine. Kenta tricks her into losing her bra and snaps a few photos of his own, [[OnceAnEpisode which is the sort of thing that happened a lot in that show.]]
* ReluctantFanserviceGirl: This is the entire concept of the show. The title character continually finds herself naked due to the actions of her perverted students, the occassional non-human, or the nature of the universe itself.
* {{Sarashi}}: She wears it once due to being in a festival as a drummer. Kenta takes it as an opportunity to get her on a bike before she can tighten her robe, and the resulting bouncing causes the sarashi to come undone. He doesn't stop the bike, leaving her bouncing around complaining and a large horde of shocked and happy neighborhood men looking on.
* ShowerScene: Machiko frequently shower naked...even in the opening sequence!. Much like Shizuka from ''Anime/{{Doraemon}}'', even the kids join in on these, and CensorSteam is completely averted.
* SkinnyDipping: Machiko is forced in this situation since the opening where Kenta remove her costume while she swim in the swimming pool.
* ThanksForTheMammary: Machiko gets groped by almost everyone, including animals.
* VaporWear: Her bra was stolen by a crow once, and her shirt was...[[NippleAndDimed different]].
* WackyHomeroom: The series had a very colorful homeroom and the quirkiness branched off into other teachers and members of the faculty as well.
* WardrobeMalfunction: Machiko is often victim of this in alternative to ClothingDamage (in every case she will lose her dress).
* WhyDidItHaveToBeSnakes: Machiko is afraid of cats.
