[[caption-width-right:350:The Demon Lord, his right hand, the Hero that opposes him, and the junior that likes him]]

In the world of Ente Isla, a parallel universe of magic and the supernatural, Satan Jacob, the "[[EvilOverlord Devil King]]", was on the brink of conquering the world, when a Hero stepped in and thwarted him. Escaping through a magical portal with Alciel, his most loyal general, Satan vowed to return and finish what he started.

Alas, both men end up in modern-day Earth (specifically, Japan) -- whose [[YourMagicsNoGoodHere lack of magical energy]] forced them to be BroughtDownToNormal. Completely broke and nigh-powerless, they are forced to adjust to life in this unfamiliar world: while Alciel (under the alias "Shiro Ashiya") researches a way to regain their powers, Satan (now "Maou Sadao") gets a part-time job at a fastfood joint to pay for their rent and daily expenses, taking on his new role with enthusiasm and competency, quickly becoming an ideal employee and gaining the admiration of his cute co-worker, high-school-grade Chiho Sasuki.

But Maou's past is quickly catching up to him: Emilia Justina, the Hero who defeated him, has also tailed him and is set on finishing what she started... only to discover that she, too, lost much of her powers, and finds herself reduced into a mere call-center agent under the name "Emi Yusa".

Of course, much HilarityEnsues, but at the same time, now that they're stuck in the same boat, so to speak, Satan/Maou and Emilia/Emi would have to work together and cut back on the vitriol (especially on the latter's part) if they want to return to their world, in the process discovering that perhaps the situation in Ente Isla may not be as black-and-white as most would rather have it be.

''Hataraku Maou-sama!'' ("The Devil is a Part-Timer!" or "Overlord At Work!") is a LightNovel series written by Satoshi Wagahara and illustrated by Oniku. It has two separate manga adaptations and, as of Spring 2013, an anime adapting the first two books in the series.

----
!! ''Hataraku Maou-sama!'' provides examples of:

* TheAbridgedSeries: [[http://www.youtube.com/watch?v=XfsuZdqnP2U Here]].
* ACupAngst: Emi, but subtler than most other examples. Every time Chiho shows off her... [[UnusualEuphemism pair of one-pound hamburgers]], expect the Great Hero to develop DullEyesOfUnhappiness. The first thing she does when she meets Suzuno? Stares at her chest portion before sighing in relief.
* AgonyBeam: Sariel uses this on Emi in episode 12 in an attempt to retrieve her holy sword. Although there are no visible wounds on her, she screams in pain every time it's used on her.
* AlienSky: Ente Isla is depicted as having two moons in the anime.
* AllJustADream: Both Emi and Chiho have these in episode 13:
** Chiho [[spoiler:sees Maou leaving Earth for Ente Isla, and he refuses to let her go with him.]]
** Emi, meanwhile, [[spoiler:sees everyone at her workplace disappear, followed shortly by Maou appearing in the sky, having taken over the city.]]
* AllThereInTheManual: The character files (presented in the resume format) in the light novels reveal some interesting personal details (amongst some funny annotations) about the characters of the series:
** [[ReallySevenHundredYearsOld Ashiya and Maou are really old]]. In fact, Ashiya is so old that he was already active in the demon army before Japan adopted the era calendar scheme (in AD 645).
** Emi scored 700 (out of a maximum of 990) in the [=TOEIC=][[note]]Test of English for International Communication[[/note]].
** Chiho holds a [[KyuAndDanRanks 1st dan]] rank in kyūdō, or Japanese archery, which is referenced by her brief archery scene in the OP animation.
** Suzuno passed the level 1 (the highest possible) Kanji Aptitude Test.
** For Urushihara's file, see the [[Funny/HatarakuMaousama Funny entry]].
* AmusingInjuries: In episode 12, after rescuing Emi with her dress shirt slightly unbuttoned, Maou comments on it. She turns [[HighPressureEmotion bright red]], and in a couple of scenes later, he has a red handmark on his face, presumably from having gotten slapped rather hard.
* AntiMagic: [[spoiler: The manager of Sentucky]], revealed to be the Archangel Sariel, has the ability to nullify Emi's sacred magic, [[spoiler: allowing him to [[BadassInDistress overwhelm and capture her]] in episode 11.]]
* ArsonMurderAndJaywalking: When Emi's ranting to Rika about why she hates Maou she says that he is cruel, greedy, thoughtless, lacks common sense, and that he acts like giving her an umbrella is a big deal.
* ArtShift:
** Happens to Chiho briefly in episode 8 when Suzuno says she's looking for a job, and Maou innocently suggests she work with him and Chiho at [=MgRonalds=]. During the transition, she also develops DullEyesOfUnhappiness. The scene basically plays out such that the quality of art by which she's drawn drops each time she hears something that makes her unhappy.
** In episode 9, the art style changed to sketch-like shots when Ashiya is "explaining" to Rika about he and Maou's relationship with Emi.
* BadassBystander: The convenience store clerk who helped to chase away the mysterious assailant cornering Emi in episode 7.
* BattleStrip: Maou decides to fight [[spoiler:Suzuno and Sariel]] in just his undies to prevent damaging his work uniform.
* BeachEpisode: Well technically they're at a theme park with a giant pool in episode 10, but Emi, Chiho, and Suzuno are all clad in swimsuits for most of the episode.
* TheBeastmaster: Maou uses this trope once in episode 10 [[spoiler: to control the alligators which escaped their cage earlier and keep them from attacking anyone. Suzuno, who witnessed it along with Emi and Chiho, is shocked that he's using his powers to help people instead of for his own selfish use.]]
* {{Beat}}:
** Used several times when Alciel and Satan first arrive on Earth. Alciel tries to use some powerful magic or something with a dramatic pose. The scene then pulls back slightly to show that nothing happens. The second time this was preceded by some ominous music, which cut out during the beat to further play up the silliness.
** When Maou finally reveals the second deck of the lunch box to Chiho, everything goes dead quiet.
* BelligerentSexualTension: Played with between Maou and Emi. Whether actually real or, as Emi keeps objecting, ''definitely'' NotWhatItLooksLike is up in the air.
* BerserkButton: Emi anytime a reference is made to her bra size. She promises to brutally murder an archangel for just this reason.
* BigDamnHeroes: Maou pulls this off a couple of times, first with the fight against Lucifer, later at the amusement park [[spoiler:when he took control of the alligators to prevent them from attacking humans]], and against Sariel in episode 12.
* BigWhat: Both Emi and Suzuno in episode 8 quite loudly [[spoiler: after the former realizes that the latter is also from Ente Isla and the latter realizes the former didn't till now.]]
* [[BizarreAlienBiology Bizarre Demon Biology]]: Apparently demons have multiple hearts.
* BlandNameProduct:
** The fast-food joint Maou works at is called [[WcDonalds MgRonalds]].
** In the first episode, the series that one of the billboards was advertising is called "[[Literature/HarryPotter Holy Potter: Blood of a Sorcerer and a Dragon]]".
** Emi works at the Docodemo Phone company (for the biggest phone company in Japan, [=DoCoMo=])
** Unislo (for Uniqlo).
** Lucifer owns and values his [[PlaystationVita Pasta (Vita)]]. He's seen buying a copy of ''[[VideoGame/DemonsSouls Devil's Souls]]'' for it online.
** Apparently Lucifer was also looking at a [[Nintendo3DS C4D (3DS)]] game on the internet
** Emi's Relax Bear wallet is a play on stationery company San-X's bear mascot, Rilakkuma
** The online shopping site that Lucifer frequents is called Jungle, an expy of Amazon.
** Lucifer also uses a search engine called "Wahoo!".
** Nobody does chicken like ''[[KentuckyFriedChicken Sentucky Fried Chicken]]''.
** Emeralda is seen enjoying her Bocky (Pocky) in her lab.
** Moonbucks coffee!
** Suzuno used to watch ''[[Manga/LoneWolfAndCub Lone Lion and Cub]]'', among other things.
** Sugiya, the restaurant Maou frequently buys pork bowls from to feed Lucifer, is based on the Sukiya restaurant chain.
* BlankWhiteEyes: Chiho displays some when she asks Maou to open the second layer on the lunch he brings to work in episode 7.
* BookEnds:
** In the first episode, Maou gives a girl, who later turns out to be his arch-nemesis Emi, his umbrella. In episode 13, she returns the favor to him after he's caught in the rain without one, on the opposite side of the corner where he first gave her his umbrella.
** The season both begins and ends with a bowl of "khatsu-dum".
* BoringButPractical: In episode 5, Olba shoots Maou with a gun. He then explains that he has to conserve his magic power to reopen the gate back to Ente Isla. HE doesn't screw around either, he just shoots people around the heart area and in the leg and tries to pull off pot shots from behind them. In contrast, Lucifer shoots Maou with a beam that creates a large hole in his torso. [[spoiler: Which likely would've killed him had Maou not had the foresight to teleport himself and Emi into a large crowd of people to restore his powers through their fear.]]
* BrainBleach:
** Miki-T sends Maou a photo of herself in a bikini. Maou and [[FanDisservice the audience]] are spared from the horror, but Lucifer faints upon seeing it and Ashiya vomits uncontrollably.
** Maou initially scolds the both of them for being demons affected by a simple photo. Lucifer calls him out on this and insists he take a look himself. Cut to Maou staring fearfully at the photo covered by its envelope (with just the bottom partially revealed, displaying the initial curve of the landlady's thighs) with slow zoom in and ominous music more befitting for an eldritch abomination's artifact. He immediately changes the subject to Lucifer's chagrin.
** Maou eventually saw it (by accident) after Chiho found it in their workplace, thought it was a letter for Maou and [[UnwittingInstigatorOfDoom placed it on a table for him]]. Cue ColorFailure.
** Ashiya attempts to weaponize it against whatever enemies may await them in the forbidden classroom scene, but fortunately he never gets the opportunity to do so.
** Another letter with a photo arrives from the landlady through Suzuno. When she mentions it and starts pulling it out to give them, time slows down (with her voice getting distorted)and colors fail as we switch to Maou's and Ashiya's growing horrified expressions.
*** The subbers even lampshaded this by showing only part of the sentence when she started and revealing the rest only when she actually said the words and revealed the letter. The end of the sentence is even translucent and faded where its spoken equivalent is distorted by time slowing down.
* BreatherEpisode:
** Episode 6, in stark contrast to the high paced action previous episode, is largely filled with a lot of comedic hi-jinks.
** Episode 13 has nothing too serious occur, and is fairly light-hearted compared to the previous episode where Maou was once again in a fight for his life.
* BroughtDownToNormal: Magic doesn't flow on Earth as in Ente Isla, and so the visitors have to get by as regular humans until they figure out how Earth's magic works.
* BrownNote: It takes a lot to horrify the likes of Demon Lord Satan and his loyal general Alsiel, who have each had centuries of combat experience to harden their hearts. Yet, a single picture of their {{Gonk}} landlord in a bikini is enough to [[GoMadFromTheRevelation utterly break them.]]
* CasualDangerDialogue: During the fight with Lucifer, Maou and Alciel argue about money.
* ChekhovsGun:
** Random earthquakes that aren't so random. [[spoiler: They were sonar pings used by Emi's companions in order to locate her on Earth. They later explain in episode 5 that it was specifically targeting those who were thinking about the Dark Lord, hence why Chiho was subjected to them as well.]]
** The string of muggings. [[spoiler: Maou deduces that the muggings were to put fear into people that Lucifer could then feed off of to regain some of his powers.]]
** Emi's missing wallet. [[spoiler:Lucifer is the one who finds it, and is able to use her contact information to his advantage]].
** Holy Vitamin B [[spoiler:helps Olba regain enough magic to bring the moon closer for Sariel in episode 12.]]
* ComicallyMissingThePoint: In episode 10, Chiho visits the theme park that Maou is asked to work at for the day to help with the busy schedule. She's wearing a revealing swimsuit, and asks how it is. He then tells her that it's a lot busier here than in the store they normally work at, and as he goes on about the work, she increasingly becomes irritated at his ObliviousToLove mentality (which Emi calls him out on moments later), showing off some DullEyesOfUnhappiness shortly afterwards.
* CompanionCube: Dullahan, Maou's trusty steed and most certainly not just a cheap bicycle. Starting to reach insistent terminology levels.
* CorruptChurch: [[spoiler:The Holy Church of Ente Isla turns out to be one. Their plan was to raise Emilia as a TykeBomb and secretly sabotage the war effort so that the fate of the world fell on the shoulders of their chosen "Hero". Then after Emilia defeats Satan, the Church quietly gets rid of her (by faking a HeroicSacrifice) so that they can take the credit and political influence. They even used Inquisitors to act as their own personal secret police and eliminate anyone who stood in their way. Though High Priest Olba is the chief architect of this, the other higher-ups aren't much better]].
* CrapsackWorld: Even though Ente Isla is ([[IntendedAudienceReaction very intentionally]]) a bog-StandardFantasySetting, it still starts to reek of this as we learn more about it. See CorruptChurch above.
* CrashIntoHello: How Maou and Kamazuki meet, thanks to the seemingly cursed stairs.
* CryCute
** PlayedForLaughs with Emi in Episode 2, being reduced to tears while begging Maou to open up the door for her, then more seriously at the end of said episode after she had to accept Maou's generosity in allowing her to stay at his (and Alciel's) place for the night after she lost her purse.
** Chiho does this a few times.
** In Episode 11, Suzuno breaks down in tears after [[spoiler:Emi decides to side with Chiho -- both girls she came to trust -- in sparing Maou, at least for the moment]].
* CurbStompBattle: Maou vs. anyone once [[{{LetsGetDangerous}} he gets serious.]] Special mention goes to Maou vs. Sariel, the aftermath of which could be seen ''from space.''
** Emi is on the receiving end of this fighting Sariel, who can cancel any holy powers.
* DarkIsNotEvil: If Maou and Ashiya are anything to go by while on Earth.
* DatePeepers: Emi and Ashiya do this in episode 3 while Maou is out on a date with Chiho.
* DefeatMeansFriendship: Once Maou [[spoiler:defeats Lucifer, he takes him in. Thus Lucifer stays at Maou and Alciel's home, so he doesn't cause further trouble, and helps them searching for sources of magic on Earth.]]
* DivingSave: Maou protects Emi in this way when they're unexpectedly fired on.
* DoubleStandardAbuseFemaleOnMale: After Maou catches Emi when the latter falls down the stairs at his apartment, he calls her clumsy, prompting her to viciously punch him, followed shortly by a brutal kneeing to his face. However, in this case, Emi doesn't escape unscathed, as he was holding her at the time, and when he drops her, she lands on her upper back and head in a rather painful manner.
* EmbarrassingRescue: In episode 12. Emi's too spent from torture to [[ComplainingAboutRescuesTheyDontLike properly complain about it,]] though - even having her ripped-open blouse pointed out barely warrants a reaction.
* EmotionalPowers: On Earth, demonic powers are powered by fear, despair and sadness while sacred powers are powered by love. It's rather difficult to restore sacred powers as a consequence.
* EmotionEater: Supernatural Ente Islans can gain magical power from human emotions.
* EnemyMine:
** When confronted by [[spoiler:the traitorous Lucifer and a power hungry Olba]] Emi, Maou and Alciel work together to bring them down. They constantly bitch about it during and after the event.
** In episode 8, [[spoiler: Suzuno suggests this to Emi, but the latter refuses for a variety of reasons, such as Maou saving people's lives in an earlier attack.]]
* EpicFail: The masked assailant who attacks Emi at the convenience store in episode 7. He rushes at her...only to slam into the sliding glass door.
* EverybodyKnewAlready: Turns out Maou and his roomies all knew from the beginning [[spoiler:Suzuno was actually from Enta Isla. They just didn't bug her about it because it's free food and not a big deal to them. Lucifer even remarks on how the food tastes a little Sacred for his liking.]]
* EvilIsBigger: Satan and Alciel's Demon forms were bigger than the Hero Emi. Their human forms are much smaller, though, so when Maou temporarily regains his form, his clothing is instantly stretched to the breaking point over his frame.
* EvilIsPetty: In addition to the whole 'conquer the world' thing, Ashiya says he would steal the keys of someone who had done him a favor, while Maou seems to feel it's his job as an overlord to annoy Emi. They even prank call her at work to test Lucifer's hacking skills (her expressions during this scene are hilarious).
* EvilOverlord: Maou was one, but now he's just an employee at a fast food restaurant. This doesn't stop him from retaining his [[LargeHam old dramatic tendencies,]] however.
* EvolvingCredits:
** The series initially had a placeholder opening as well as ending, despite having the accompanying songs for both. The first two episodes have no opening. The third episode starts with the cuts taken from the light novel covers, before transitioning to using flashbacks and scenes from the first two episodes, to finally showing the fully-animated version in episode 05. Even the "real" opening animation features slight changes between episode 5 and 7, like going from showing just Maou, Ashiya, Emi, and Chiho during the walking sequence, to including [[spoiler:Lucifer and Suzuno, incidentally spoiling the latter's identity as the Church Inquisitor]]. All this is because the studio, for whatever reason, couldn't complete the actual opening on time.
** The ending placeholder, on the other hand, is initially a reverse replay of the first episode, then transitions to a basic animation taken from the light novels, then goes to a [[MsFanservice slow pan-up of Chiho while wearing a bikini, sun hat, and semi-transparent sundress]] (which had been drawn by the director). The final ending sequence that appears in Episode 06 still retains that particular pan-up, but shows a whole lot more montages -- including Chiho sitting seemingly naked covered only by a round cushion, as well as wearing a bunny-girl outfit. It's still very much Chiho-centric however.
*** The pan-up in Episode 06 now shows multiple but faint clocks appearing on Chiho's body.
*** The ending credits change again for episode 13, showing slice-of-life moments for the main cast after everything's wrapped up.
* ExpectingSomeoneTaller: Chiho figured that supernatural entities would be a bit more impressive. Emi concedes her point.
-->'''Chiho:''' I'm sorry! I always thought angels and demons and stuff would be more... like, imaginary and amazing.
* ExplainingYourPowerToTheEnemy: While fighting against Emi in episode 11, Sariel took the time to explain his unique ability to [[AntiMagic nullify her sacred powers]] to Emi. Granted, he had absolute confidence in his abilities and that no-one else would hear it.
* FantasticComedy
* FantasticRacism: '''[[DefiedTrope DEFIED]]''' by Maou. The only reason he fought humans in the first place is because they were in the way in his goals. It also help that he's in the situation where he ''has'' to work with humans if he is to succeed in world dominaiton.
** Played straight by Emi. Justified that [[YouKilledMyFather she lost her father in the war against the demons.]]
* FemaleAngelMaleDemon:
** The three demons of the cast are male (with the FallenAngel being the most feminine-looking of the trio) while the [[HalfHumanHybrid half-angel]] hero is female with her angel half stemming from her mother.
** Subverted in the case of Archangel Sariel... though he still looked rather feminine as well.
* {{Filler}}: Apart from Suzuno's arrival at the end, the majority of Episode 6 is an anime original.
* FishOutOfWater: Everyone from Ente Isla adapts quite fast to life in Japan, and not in the VillainsBlendInBetter or LikeAFishTakesToWater ways: they [[GoingNative go completely native]]. It helps that there are time skips during their adjustment phase but it's implied they do take well to their new lives (albeit with a naivety concerning subtle details of daily modern life).
** Played very straight with Suzuno, who is not only a fish out of water but a fish out of temporal water as well. This severely complicates her adjustment compared to the others. She argues with a train station gate insistently blocking her way and stereotypically freaks out about a flatscreen tv having "tiny people" in it. Even after being corrected, she's shown to be hard-locked into some habits such as speaking Japanese in a very old, formal and traditional style and wearing kimonos (she still buys more kimonos during a shopping spree when told about western clothes and given magazines about them). This just seems to be her personal preference however.
* FoodAsBribe: In episode 9, Ashiya makes himself known after hearing Emi insult Maou inside the SFC restaurant. At first it seems things are going to end up in a [[HamToHamCombat very heated argument]], but then Emi offers to buy him some dinner if he'll tell Rika about Maou. He immediately accepts and sits down, proclaiming that there's nothing he wouldn't do for Maou and to save on their money.
* FourIsDeath: Satan's Four Generals. At least one has turned traitor.
* FreezeFrameBonus: In episode three, if you go frame by frame through the collapsing tunnel scene you see [[spoiler: magical barriers going up around the people as Maou protects them.]].
** The gestures and body language of the characters is well animated. Some of these occur in less than half a second. During the lunchbox scene, pay attention to Chiho's expressions and how she throws herself across the table to grab, yank and then shake Maou. Emi is a powerhouse of expressions to the point where you can read the escalating stages of "pissed off" she's going through in a single moment.
* FriendlyEnemies: "You are a ruler of demons! You cannot [[GoKartingwithBowser party the night away with some hero]]."
* FriendsRentControl: Maou's apartment is pretty small, but of the two (later three) people living in it, only one is employed, and he has a part-time job at a fast food restaurant.
* FunnyBackgroundEvent
** When Emi tries storming Castle Overlord (read: knocks on the door of their one room apartment and begins yelling at them to come out and fight) Alciel locks the door and begins discussing the situation with Maou while in the backround Emi first rants at and threatens them before beginning to cry in frustration.
** When Emi and Suzuno go to Moonbucks, Suzuno copies Emi's gestures - being out of touch with modern Japan, she sees Emi as being more experienced. When she copies Emi spilling some cream for her coffee, she makes a triumphant fist for a brief moment at having gotten it 'right.'
** Suzuno again in Sentucky. After taking their seats, look at her face for the entire length of the scene while Rika and Emi bicker. She takes a small sip of her drink and then just stares at it the entire time as if it's the nectar of the gods.
** Lucifer often complains about how poorly he is treated by the other characters, who, of course, ignore his rants, relegating him to background noise.
* GilliganCut: In the first episode when Satan and Alciel arrive on Earth they encounter a pair of police officers who try to make them get in the police car. Alciel leaps back and attempts to use magic on them, loudly proclaiming that he'll never go with them. After his spell fails, there's a {{beat}} and the scene cuts to the pair in the back of the police car.
* GirlyRun: Emi pulls it off during the opening credits sequence.
* TheGlomp: Rika does this to Chiho in episode 9 after being smacked by CutenessProximity.
* GoKartingWithBowser: Apparently, powerful heroes and demon lords spend their time chatting and snarking at each other when they're not working.
* GratuitousEnglish: Emi's "[[BlandNameProduct Relax Bear]]" wallet.
* GreyAndGrayMorality: Emi and her closest allies are genuinely heroic while Maou's greatest moral failing is his inability to lead his forces properly, causing them to go out of control against civilian targets. There are very few genuinely bad people in the cast.
* HamToHamCombat:
** Both Emi and Suzuno in episode 8 after they both realize [[spoiler: that they're both from Ente Isla.]] Their heated debate gets the attention of some passersby.
** Most of Emi and Maou's arguments start out or devolve into this eventually.
* HauntedHouse: Emi, Chiho, and Suzuno visit one in episode 10. Despite having probably seen much worse, it scares all three girls. Emi later wonders who would create such a thing, while Suzuno thought she was prepared for stuff like that. All three are holding their face, probably in tears afterwards.
* HeelFaceRevolvingDoor: Lucifer was originally one of Maou's generals, then shows up with Olba on Earth to kill him. After Lucifer's defeat, Maou accepts him back rather easily. [[spoiler: Once Olba returns, he goes to Lucifer to team up against Maou again, and Lucifer appears to agree at first. However, Lucifer turns on Olba after using him to help Maou gain the upper hand in his own fight, making this a subversion of this trope.]]
* HeroStoleMyBike: In episode 8, while walking Chiho home, Maou brings his bike along to go to work afterwards. After she gives him a LoveConfession, they realize Suzuno was watching them. Chiho then grabs his bike and starts taking off with it, and apologizes profusely later for it.
* HeroesGoneFishing[=/=]VillainsOutShopping: The premise of the series, basically.
* HighSchoolAU: One of the manga adaptations, with Maou now an ambitious high school student.
* HowMuchDidYouHear: To Chiho's dismay, Suzuno heard everything after "I'd already fallen for you, Maou-san."
* HugeGuyTinyGirl: Albert and Emeralda. Also, Maou and Emi - there's not much of a size difference (if any) when he's human, [[http://www.baka-tsuki.org/project/images/0/0b/Hataraku_Maou-sama%21_v4_p318.jpg but as a demon...]]
** Also Maou and Chiho - the latter is already much shorter than even human Maou but in his demon form...
* HumanityEnsues: The rules of Earth's reality don't give much leeway for the cast to keep their demonic/angelic traits and powers.
* HumanityIsInfectious: A despotic Demon Lord and a Half Angel Cold-Hearted Heroine are no match against the everyday kindnesses of PresentDay Earth.
** Same goes for a sociopathic backstabbing Fallen Angel.
* HypocriticalHumor: In episode 6, Emi pays a visit at Maou's restaurant, saying she wants to talk to him. He tells her that disturbing him at work is extremely rude, which causes her to immediately call him out on this, as he had called her while she was at work the day before.
* ILied: In episode 12, Lucifer runs into Olba again. The latter offers to work together again, and Lucifer agrees to it. [[spoiler:However, he tricks Olba into summoning the moon closer to get Sariel into a false sense of security, and helps Suzuno cause panic on the streets to give Maou some magical power, then knocks out Olba and ties him up once he's got Emi's bag back.]]
* ITakeOffenseToThatLastOne: Emi and Chiho call Sariel a pervert numerous times and he angrily denies the PantyThief accusation.
* IgnoredEnemy: Confronting Lucifer is not as important as lecturing Maou on his movie expenditures.
* InvoluntaryShapeshifter: When Satan and Alciel come to Earth, they become human with very little magic. [[spoiler: They can become their true demon form again when they get enough magic, like when Maou grows to his true size in episode 3.]]
* IsItSomethingYouEat: Suzuno asks this when they are about to visit the reptile house in episode 10. She then relates to Chiho a story of how she was invited to eat some down south.
* KnightOfCerebus: [[spoiler: Sariel and to a lesser extent Suzuno. Both their arrivals mark the part where the comedic nature of the story is toned down a little and things get serious.]]
* LawyerFriendlyCameo: [[Literature/HarryPotter Holy]] [[http://thecartdriver.com/hataraki-maou-sama-episode-1-holy-potter-blood-of-a-sorcerer-and-a-dragon/maou102/ Potter.]]
* LettingTheAirOutOfTheBand: When Emi reveals her true identity and confronts an aghast Maou, and threatens him with death, she pulls out a knife to show she means business. An unimpressed Maou then recognizes it as being a dollar-store (and very small) knife bought from nearby and [[SoundtrackDissonance the music]] slowly fades out before getting back into gear as she regains her composure and charges at him full tilt with it. Hilarious in that his reaction is not smug or sardonic, he's blank and completely unthreatened by its presence.
* LightIsNotGood: Everyone we've seen aligned with Ente Isla's CorruptChurch has been a KnightTemplar at best and a power hungry monster at worst. These people wield explicitly divine power.
* LockedOutOfTheLoop:
** Rika, in episode 9, attempts to pry some information out of Emi regarding her exact relationship with Maou. Interestingly enough, none of the characters who talk to her mention anything about Ente Isla, and instead describe things to her that isn't entirely out of context from their point of view, but to Rika, sounds like they have a bitter rivalry due to working at competing companies in the past.
** Chiho to a lesser extent. Although she knows a little about Ente Isla from Maou and Emi, she's initially unaware [[spoiler: that Suzuno is also from there]].
** StatusQuoIsGod: Things stay like this for ''eight books'', until Rika finally forces the issue [[spoiler:when Emi suddenly disappears without a word, apparently taking Arras Ramus with her. Much like Chi-chan, she takes the revelations quite well.]]
* LouisCypher: Maou Sadao (真奥貞夫) is one of the most blatant ever, although he's never called on it by anyone except Ashiya. A semi-literal translation would be "John Secretlythedevil" and the official English translation is "Jacob Satan".
* LoopholeAbuse: In episode 13, Lucifer ends up buying a lot of items which Maou's apartment has no use for, nor can he fit inside, such as seven beds. He tries to return the items, but the business owner refuses to take them back, since they were legally purchased. As Maou and Ashiya try to figure out what to do since he now owes a lot of money for those items, Emi asks how old Lucifer is considered in human years. After Maou tells her, she gives him a way out, by telling him about "cooling off". [[spoiler:Since Lucifer is technically under Maou's guardianship, he's not allowed to spend that much without Maou's approval, so they utilize that loophole to get the business owner to take the items back and not owe him any money.]]
* LoveTriangle: Chiho is in love with Maou and thinks that Emi is her [[TheRival rival]] despite all of her [[HeIsNotMyBoyfriend strong objections to the contrary]].
** After that gets settled to Chiho's satisfaction, she finds out about Suzuno, who she assumes has a crush on Maou.
* MaleGaze: Episode 7 gives us a shot of Emi's sweat-soaked shirt and the bra she's wearing underneath.
* MissingStepsPlan: Emphasized; Maou's EvilPlan? Climb up the employee ladder at [=MgRonalds=], TakeOverTheWorld.
** This is in fact a running gag, each raise and promotion a step forward to his goals. When he becomes assistant shift manager, Chiho (who knows of their origins at this point) even brings up the fact that he technically has human underlings now under his power (with added hilarity from Emi appearing and saying she'll never allow it in typical hero fashion... for a mundane situation).
* MistakenForGay: Maou and Ashiya with some frequency. Half the time Ashiya acts like a harassed housewife and Maou like a henpecked working husband. Also they've started to get much closer (in a bro-ship manner) and their relationship, while retaining the general undertones, has long since progressed past the boundaries of a regular villain and his loyal dragon.
** *Maou and Ashiya joyously hugging each other* Lucifer in foreground - "...boneheads..."
** This starts really early on in the manga, when Ashiya and Maou are setting up their family registry. The old couple watching them thinks they're getting married.
* MomentKiller:
** Emi stops Chiho from an attempted LoveConfession to Maou in episode 3.
** While it's not a romantic moment for them, Chiho and Ashiya interrupt the argument Maou and Emi were having just moments earlier. However, it's played straight for Chiho, who suspects Emi is really dating Maou when she finds the two at his apartment.
* MoodWhiplash:
** During the fifth episode, the story takes a much more serious turn, but to keep things from getting too heavy the story makes sure to pull out its usual humor every now and then, flipping the story between drama and comedy quite quickly.
** In episode 11, [[spoiler:the masked attacker shows up again, and delivers a CurbStompBattle to Emi. Suzuno also seems to be helping him, although all she seems to do is keep Chiho from interfering/getting hurt.]]
** Episode 12 is heavy on the action and drama, [[spoiler:first with Ashiya being attacked by Olba, then Emi being tortured with an AgonyBeam, and later Maou getting beat up rather badly first by Suzuno, then Sariel, before getting some power back and returning the favor to the latter.]] Like the fifth episode however, it also has its comedy in between to keep the mood from getting too dark, such as Maou taking off his work clothes before fighting to avoid damaging them and having to pay for a replacement pair.
* MundaneMadeAwesome:
** Ashiya attempts to use magic when he and Maou first land on Earth. Although he tries to make it dramatic, to the cops, it just looks like he's cosplaying.
** Emi threatens to take down Maou when they first have a serious conversation in a very LargeHam fashion. She then pulls out a really tiny knife, which he isn't threatened by in the least (he even blankly reveals that he knows where she bought it: at the local Japanese equivalent of a dollar store).
** Maou talking about incinerating and enjoying eating something at the beginning of episode 6, only to then reveal that he and Ashiya were at a restaurant. The latter points out that the former's weirdness was freaking out the other customers.
** The intro has an over-animated scene of Ashiya chopping vegetables and shaking dirt out of a pair of boxer shorts.
* NamedWeapons: Emi's holy sword is named "Better Half". This is also a MeaningfulName as well -- "Better Half" can only be used by a half angel, half human hybrid.
* {{NEET}}: When Lucifer winds up moving in with Ashiya and Maou, it takes him almost no time at all to go from a feared FallenAngel and general in the Demon Lord's army to a lazy layabout.
* NotTheFallThatKillsYou: An unconscious Chiho is tossed carelessly to the side by Lucifer from quite a height. Emi manages to catch her and she's fine. Oddly enough, though, the impact breaks ''Emi's'' legs.
** Considering how far away she was and how fast people fall, Emi probably boosted her speed to catch Chiho and didn't think about the effect the impact would have on her [[RequiredSecondaryPowers human knees]].
* NotWhatItLooksLike: Maou and Emi tend to get into a ''lot'' of public spats (usually due to the latter freaking out over one thing or another), which make them look like a couple having an argument. As noted by one of the other entries on this page, Emi usually blushing immediately afterwards only helps strengthen the impression for bystanders.
** Chiho walks in on them talking in his apartment and runs away crying and the landlady [[TheMissusAndTheEx misunderstands the situation.]]
** In episode 8, Suzuno inquires more about what Emi's exact relationship is with him. [[spoiler: She's shocked to find out the hero doesn't want to outright kill Maou after hearing that he saved a lot of people from Olba and Lucifer's attacks in earlier episodes.]]
* OneDialogueTwoConversations: Emi and Suzuno's exchange in episode 7/the start of Volume 2. Emi thinks another girl has a crush on Maou while Suzuno assumes her cover is blown. Which doesn't happen until they do the same thing the next episode.
* TheOnlyOneAllowedToDefeatYou: Emi's attitude towards Maou.
* PantyShot: Emi gets one in episode 7 when the stairs try to take her out again. Original in that she's far from the screen and it's not highlighted/enhanced in any manner, so you may not notice it unless it's pointed out ([[CovertPervert or otherwise orientated towards noticing such things out of hand]])
* PerpetualMolt: Any character with wings.
* PerpetualPoverty: Maou and Ashiya, unfortunately. Emi's only a little better off (to her initial chagrin when she realizes her day is about the same as theirs).
* PleasePutSomeClothesOn: In episode 12, Maou begins to strip off his work clothes [[spoiler: when confronting Suzuno, causing her to blush and cover her eyes.]] He then explains that if his work clothes get damaged outside of work-related use, he has to pay for replacements. He also ends up fighting [[spoiler: Sariel]] with just his boxers, socks and shoes on.
* PottyEmergency: Ashiya spends much of episode 10 locked in the bathroom because he ate too many noodles due to trying to finish them off before they expired the next day.
* ThePowerOfLove: In the manga, Emi guesses that magic on Earth may come from the human heart, be it love (for her) or fear (for demons).
* PurpleEyes: Apparently a racial trait for Angels. [[spoiler:Becomes an actual plot point, as later books reveal that only angels born after the cataclysm caused by an ancient overlord have these as a feature.]]
* RashomonStyle: Very briefly. We see the original war at the very start of the series from largely human perspective: Demons fighting humans and demons killing villagers. Emi has a flashback about how her father's village was destroyed. However, we later get a different interpretation from Ashiya's perspective as he relates a mundane version of the situation to Rika. To him, the demons were the underdog struggling to survive while Emi represented a larger, stronger group that eventually crushed them with resources. From his perspective, Emi's group had no malice but his group was doing nothing wrong, making them more rivals than anything. His view of events can be rather telling when it comes to interpreting his actions and attitudes.
* ReactiveContinuousScream: Chi was blushing about Maou for a moment when Emi's friends tease her, then he walks into the room and she begins hilariously screaming in surprise. Maou and then Alciel then [[http://www.youtube.com/watch?v=KjXd8HJvE78 scream just as hilariously]] in response.
* RealityEnsues: Since Emi and Maou's are not humans in their world (half angel in Emi's case) and posses innate abilities like defying gravity, break castles with their hands, being punched through buildings without hurting themselves and use god-like level magic with ease, becoming humans had led to such shocking revelations as:
** Maou, forgetting that he is human, neglected to eat anything throughout his first day in Japan and ended up passing out from hunger.
** There is no such thing as TalkingIsAFreeAction and evil monologues are just plain stupid.
** Emi can't even knock down a door, breaks both her legs catching Chiho as she falls from a great height and learns that if you fall down even 3 feet upside down onto the back of your head it is going to hurt so terribly bad that you will squeeze into a fetal position, hold your head tight with both arms and squeal like a pig. Welcome to being a human in our world.
** Having no earth education or even papers, you end with low end jobs and living in medium low (or sometimes plain poor) salaries after months of hard work.
** Out of the things Maou learns, the most notable is that BULLETS HURT LIKE HELL and wondering how is it possible for humans to handle so much pain. As a demon he can have holes through his body and not even be bothered.
* ReasonableAuthorityFigure: The police in this show are not useless, but they seem really lax on the uptake! The police officers in the first episode think that Satan and Alciel are tourists who were mugged and only want to help, and later on, another one thinks they're actors rehearsing a play and laments his own failed pursuit of acting.
* ReassignedToAntarctica: Maou's manager talks about this after a former coworker was sent to a remote [=MgRonalds=] for letting business slip after a rival restaurant chain opened up nearby. She then threatens Maou with it as well.
* RunningGag
** When not on her job, Emi is determined to carry out her vigil (read: stalk) on Maou and co. She constantly runs into him performing mundane or innocent actions with the assumption that he's up to no good. Wherever Maou goes, it's safe to assume Emi is not too far away.
** Alciel acting like a harassed loyal housewife. He saves money secretly, does the housework, avoids spending for his own leisure, manages expenses and purchases, often scolds Maou and Lucifer for wasteful spending, actively seeks opportunities to save (even at the cost to his honor and pride without hesitation) and even keeps an eye on all the bargains and discounts that are both active and seasonal. Even when [[spoiler:gravely wounded from a gunshot to the chest, his last words for Maou before passing out are to take advantage of the month-start bargains were he to expire]].
** Chiho's misunderstandings about women going after Maou. Justified because to an outside observer, Emi looks like a stalker, and that bento Suzuno gave him was certainly well-prepared.
** Maou may be empathetic, good natured, caring and dedicated but he can't help occasionally indulging in his Overlord tendencies when given the least bit of opportunity. Emi and Ashiya are only a little bit behind him in this regard. Ashiya even goes as far to [[spoiler: retrieve his attire as Maou's general after being healed from near-death and bestowed a level of magic power before launching into the fight]]. They do come from a world where Hammy behavior is the norm (and serious business) for people of their status and ability.
** People [[StaircaseTumble falling down the stairs]] of Maou's apartment. [[SweetBroAndHellaJeff It keeps happening.]]
* SafetyInMuggles: When they're being fired on by an unknown and otherworldly assailant, Maou and Emi race to the nearest train station with the assumption that there will be more people around there.
* ScreamsLikeALittleGirl: Both Ashiya and Maou do this in episode 6 when Chiho tells them about some urban legends at her school, including one with a cell phone that rings when you find all seven mysteries there. They both try to disregard it at first, but then Maou's cellphone rings, hilariously causing both of them to freak out.
* SeriousBusiness: Competing fast food restaurants. To Maou, his part-time fast food job. Every raise and promotion is a major victory.
* ShoutOut:
** Besides being a BlandNameProduct stand-in, ''Docodemo'' (meaning "wherever/anywhere" in Japanese) is usually associated with a certain robotic cat called ''Anime/{{Doraemon}}'' and his pocket space-time gate.
** An annoyed Alciel complains about the idea of their meals being [=MgRonalds=] leftovers for the rest of the month and mentions ''Film/SuperSizeMe'' when going on about how unhealthy that is.
* SlapstickKnowsNoGender: The [[StaircaseTumble staircase of doom]] is out for everyone's blood, chromosome pairing be damned.
* SmugSnake: The SFC manager across the street from the [=MgRonalds=] store Maou and Chiho work at gives off this vibe, which irritates both of them. He later does this to Emi and Rika as well, and both women also get disgusted by his actions.
* SoundtrackDissonance: The anime loves playing really dramatic music. Given who the characters are and what was going on before the story got going, you can tell it's music that would fit the war that was going on beforehand. Now? Now it's when Alciel attempts to cast magic and instead calls a taxi or when Maou boasts about his plan to conquer Japan by becoming a full time employee at [=MgRonalds=].
* StabTheSalad: Grilled innards have much to fear from Maou.
-->'''Maou:''' [[foldercontrol]]

[[folder: How does it feel to be helplessly incinerated by the flames? Your flesh, your guts, and even your bones will be consumed to fuel my ambitions! Let the feast begin! The first sacrifice I shall accept... will be you! ]]

* StaircaseTumble: The staircase of Maou's "fortress" evidently bears a massive grudge against all of humanity, especially Emi.
* StandardFantasySetting: Ente Isla
* TheStarscream: How Lucifer is introduced. He gets better after being [[DefeatEqualsFriendship pummeled by Sadao]]... mostly.
* SupervillainLair: The demon king might have to settle for a six-tatami apartment, but that isn't gonna stop him from dubbing it Castle Maou.
** As mentioned above, the stairs to their room could easily be classified as a death trap after the amount of damage it's done to visitors.
* SympatheticPOV: The more serious part of the series is drawing back from a standard fantasy setup, showing that while Emilia is really heroic, not all her allies are, and Maou, her archnemesis, is roughly morally equal to her. From the demon point of view, as explained by Ashiya, they viewed humans more like rivals than enemies and were struggling to survive.
* TastesLikeDiabetes: [[invoked]] How Miki-T (hopefully satirically) describes the (apparent) LoveTriangle between Maou, Emi and Chiho.
* ThereIsNoKillLikeOverkill: Lucifer's attempts this to Emi by burying her and hundreds of other people underneath rubble. Maou later returns Lucifer the favor by giving him a MegatonPunch with layers of magic circles reaching far beyond his magic barrier.
* ThisIsGonnaSuck: Lucifer's expression as Maou is about to punish him with a very BIG windup, followed by a MegatonPunch so powerful that the impact can be seen from orbit. Archangel Sariel also experiences this as Maou uses his Demonic Blade to drive him into the concrete. The impact can also be seen from orbit.
--> '''Sariel''': O God, save this lost little lamb...
* TimeSkip: After Satan and Alciel arrive in Japan and make their false Maou and Shiro identities, there's at least a three month gap before we see them again, fully acclimated.
** There's a two month skip between episodes 5 and 6.
* TokyoIsTheCenterOfTheUniverse: Of all the places Satan landed, it has to be Shibuya!
* TranslationConvention: For the first section of the first episode, Satan and Alciel still don't know Japanese, but the dialogue still switches to that rather than the cyphered English they were speaking before. When attempting to lease an apartment you can hear Satan's actual attempts at Japanese: His accent is awful. After this, he apparently becomes completely fluent in the language.
* TrappedInAnotherWorld: InvertedTrope.
* UndeadTaxExemption: Maou uses his limited magic to get the paperwork.
* UnusuallyUninterestingSight: When a nurse comes across a collapsed Alciel in the hall, she instantly starts fussing over him for what she assumes are more issues with his food poisoning. Directly across from him is a collapsed, unconscious police officer, whom she completely ignores, as well as Alciel's protests and attempts to tell her about [[spoiler:the newly awoken Olba.]]
* UnwittingInstigatorOfDoom: Emi's mother, Laylah. Much of the problems affecting Ente Isla in the present day can be traced directly or indirectly to something she did. [[spoiler:The foremost example being her saving the life of a lowly footsoldier in the demon armies, whom she then educated in politics, diplomacy, and warfare. The same lowly footsoldier would soon rapidly rise up the demonic hierarchy, eventually turning into the greatest threat Ente Isla had seen in three centuries: '''Maou Satan'''.]]
* UtopiaJustifiesTheMeans: The primary source of contention between Emi and Suzuno in Episode 11. [[spoiler:Suzuno wants to erase Chiho's memory and destroy all traces of Ente Isle in Japan, but although she agrees to some extent, Emi sides with Chiho against Suzuno because she believes that whatever their ultimate goal may be, it's not worth hurting the people they care about to do it, reasoning that she has to find a way to make everyone happy because that's what heroes do.]]
* VertigoEffect: A {{False Camera Effect|s}} on Emi [[spoiler: when she finds out that [[OhCrap she's been betrayed by Olba]].]]
* VillainDecay: For the sake of comedy, villains tend to start out as [[KnightOfCerebus Knights of Cerebus]] only to become complete jokes after they are defeated.
* VisualInnuendo: In Episode 10, when Chiho appears in her bikini, the scene cuts to Maou serving two one-pound hamburgers (with pickles conspicuously topping the meal for extra innuendo). When Emi is shown in her bikini, the scene cuts again to Maou, this time serving two regular burgers.
* [[WeNamedTheMonkeyJack We Named the Monkey 'Sadao']]: A mischievous monkey at the amusement park happens to be named 'Sadao'. Emi takes no restraint in taunting ''Maou'' Sadao about it.
* WhamEpisode:
** Episode 4, [[spoiler: when Lucifer, one of Satan's generals, reveals himself on Earth.]]
** Near the end of episode 7, [[spoiler: Emi is attacked by a cloaked assailant, who also gains the upper hand on her by nullifying her magic sword.]]
** Episode 11, [[spoiler: when the aforementioned assailant, revealed to be the Archangel Sariel, overwhelms and captures Emi, with Suzuno following his orders.]]
* WhamLine: PlayedForLaughs when Chiho calls Emi at the end of episode 7. She sounds extremely distraught, and tells Emi that Maou did something terrible. Emi goes into Hero "time to kill him" mode and inquires about it...
--> '''Chiho:''' [[spoiler: He brought a lunchbox with a heart drawn on the rice! Hand made! From a girl! A double decker lunchbox! A double decker!]]
--> '''Emi''' (Same serious face but now frozen with an added, understandably confused, look on her face): Huh?
* WhatTheHellHero:
** Downplayed; when Maou is vehemently threatened by Emi, due to the particular contents of the threat, he responds "That's not very heroic."
** PlayedForLaughs in episode 5, when Maou claims some lines Olba says wouldn't even be mentioned in a B-movie anymore. Ashiya immediately asks him where he had money to spend on movies, and Maou quietly pouts that he can do whatever he wants with his pocket money, which causes his friend to threaten cutting off his pocket change for that month since he's been working hard, saving money and hasn't spent a dime on himself like that since they've been on Earth.
** Reversed as What the Hell Villain? Emi is at her wits' end as Maou is more like the good guy than the bad guy and even goes out of his way to make certain others are safe, even helping her, his sworn enemy. She's been raised to hate and kill him, yet he's doing more good on Earth than she (the supposed Hero). He's supposed to be the BAD GUY! What's going on?!
** Lucifer gets called out on this too in episode 6, [[spoiler: when he has Maou and Ashiya investigate Chiho's school about a rumor that they could restore their magical power in an abandoned classroom. Turns out that it was where Lucifer and Olba stayed for a while. He had simply forgotten his handheld game console there, and wanted them to pick it back up for him. Ashiya suggests selling it to make some money, but they ultimately give it back to him, on the condition that he can only play it one hour a day.]]
*** Emi gets called out after destroying a health class mannequin with her sacred sword.
** Chiho and Suzuno have a heated argument in episode 11 regarding Maou. [[spoiler:Suzuno wants to kill Maou, but Chiho is against it, and they both argue about the various things he did, such as controlling the alligators to prevent them from attacking humans in episode 10 and fixing the highway in episode 5, or had his armies do, in the case of Ente Isla.]] Emi intervenes as well, but ultimately sides with Chiho rather than Suzuno.
** Maou gets more upset at Suzuno in episode 12 [[spoiler:that she destroyed his bike accidentally than the fact that she was trying to kill him, or at least stop him from interfering with Sariel.]]
* WhyCantIHateYou: Having spent the majority of her life either preparing or actively attempting to slay him and [[YouKilledMyFather avenge her father]], Emi is very annoyed that Maou isn't acting ''remotely'' evil enough to justify slaying. [[spoiler:And it turns out that not only did Maou ''not'' kill her father, he isn't actually dead at all.]]
* WhyDidItHaveToBeSnakes: In episode 10, Chiho, Emi, and Suzuno visit a reptile house. Chiho says she doesn't like them because of how they appear out of nowhere sometimes, and we see a brief FlashBack of her seeing a tiny reptile on her family's screen door. Emi doesn't like them either, but her FlashBack shows her fighting off against a gigantic basilisk which has [[TakenForGranite petrified]] some of her companions.
* WriterOnBoard: Naoto Hosoda, the director of the anime, is enough of a Chiho fan to include his own art of her in the ending. While it's generally agreed that he made a very entertaining adaptation, he also felt the need to push his favorite ship at the expense of altering Emi's character to be more aggressive, cutting some scenes that work against a Chiho/Maou pairing and dropping important references to Emi's mother, something that might cause some problems in season two [[spoiler:considering that she's still very much alive and quite involved in Maou's backstory as well as events of the novel itself.]] Further, scenes that put Chiho in a more negative light such as her jealousy having a dangerous side to it are quietly altered.
* YaoiFangirl: One of Chiho's friends at school gets rather excited when she finds out that Mao and Ashiya are roommates, and wonders if there's only one bed, much to Chiho's chagrin (she's already got more than enough potential competition to misunderstand/worry about)
-->'''Chiho:''' Wh- you're wrong! It's not like that! Why are you imagining that kind of stuff?!
* ZettaiRyouiki: Chiho's non-school outfit sports this in episode 13 while she's following Maou around with Emi.
