-->''[[{{Tagline}} Your Wish Is Her Desire]]''

In a quiet little town surrounded by the mountains, Tomoki Sakurai lives a peaceful life with his somewhat [[MegatonPunch Megaton Karate Chop]]-prone childhood friend waking him up in the morning. That, and the recurring dream of a girl in the sky. At the same time, school eccentric Eishirou Sugata has been witnessing an unidentified thing moving above the Earth, with nobody able to figure it out. Through a series of circumstances, Tomoki ends up being the only one around when the thing falls to Earth near his hometown. In it is a girl in skimpy clothing with angel wings, calling herself an Angeloid. Her name is Ikaros. Things just got a lot more interesting...whether our hero likes it or not.

''Sora no Otoshimono'' is a 77-chapter manga created by Suu Mikazuki (who previously wrote ''Manga/WatashiNoMessiahSama'') that spawned (currently) two anime seasons and two movie releases.

----
!!Tropes:

* TheAbridgedSeries: [[http://www.youtube.com/watch?v=K2CsSoIyPlM Apparently...]]
* AbsoluteCleavage: Ikaros' and Astraea's Angeloid outfits.
** Let's not forget [[spoiler:Hiyori's]] Angeloid outfit. [[http://images.wikia.com/soranootoshimono/images/5/53/Sora_no_Otoshimono_-_Tokeijikake_no_Angeloid_-_Large_158.jpg It's cut lower than either Ikaros' or Astraea's.]]
** And now we have [[spoiler:Ikaros Melan]] whose outfit is lower still.
** Brief though her time in the series was, [[spoiler:Siren's]] outfit also qualifies for this.
* AbsurdlyYouthfulMother: Tomoyo, Tomoki's [[AnythingThatMoves omnivorous]] mother who he takes after [[GenerationXerox almost identically]]. Aside from her hips, she looks the same age as Ei and Mikako and is actually shorter than them when not in [[SuperDeformed chibi mode]].
** This is even lampshaded when she was able to enroll herself into Tomoki's class.
* AccidentalPervert: For all Tomoki's intentional pervertedness, walking into Mikako's private hot springs was not something he meant to do. This is one of the few times it's played straight. Most of the time, this trope is averted.
* ACupAngst: Nymph. It's a bit of a sore point for her.
* AllLovingHero: Tomoki is either a parody of this or a more humane one. While a complete pervert and having many, many flaws both in character and belief; he is the most loving, caring, compassionate being in the entire Verse and ready to put his life on the line for his friends and those in need without a second thought, to the point that nine out of ten CMOA and CMOH are done by him in the series.
* AlmostKiss: Happens to Tomoki a few times in the series. With Nymph in episode 12 of the first anime and with Astraea in [[http://www.mangareader.net/sora-no-otoshimono/48/36 chapter 48 of the manga]].
* AlternateCharacterReading: All the episode titles make use of this, with the meanings complementing each other in odd ways. For example, episode eight has "amount of blood spilled" read as "festival".
* AlternateContinuity: The TV-and-movie-verse diverges from the manga at episode 11 of ''forte'', and is now a separate continuity.
* AmusingInjuries: Tomoki, very often. One notable example, he gets karate chopped so hard by Sohara that she sends him flying into the air and he crashes down a few minutes later into the pavement like a javelin. A ''[[RefugeInAudacity naked]]'' javelin.
* AnimatedActors: Episode 10's ending plays on this idea, by showcasing a montage of HilariousOuttakes from past episodes.
* AnyoneCanDie: [[spoiler: The more recent chapters of the manga have taken a far darker tone. Starts with when the two reformed Harpies kill themselves for the sake of their master, Minos.]]
** [[spoiler: Kazane Hyori also dies in chapter 70 to Chaos.]]
** [[spoiler: Tomoki dies, actually dies, in the latest chapter (71) after throwing himself between a dueling Chaos and Nymph.]]
*** [[spoiler:While he gets revived the very next chapter, Sohara isn't so lucky...]]
** [[spoiler: In chapter 73, Yoshitsune performs a [[HeroicSacrifice Heroic Sacrifice to save Sugata. Then, Sugata is stabbed in the back, and dies in the next chapter as he phones Tomoki and tells him to stop his dream.]]]]
** [[spoiler: as of the second-to-last chapter, every single character is dead or dying, save Mikako, Sohara, and Tomoki.]]
* AnythingThatMoves: As long it's a Bishonen or big boobed cutie, Tomoyo Sakurai, aka Tomoki's mother, will willingy jump their bones.
* ArtEvolution
* ArtShift: Quite frequent, from bishonen to super-deformed.
** Tomoki spends so much time in his super-deformed state that it's possible to forget that he's actually supposed to look normal.
* AttackOfThe50FootWhatever: [[CrowningMomentOfFunny About a dozen chickens, Sohara, and Tomoki in chapter 42.]] HilarityEnsues.
* AttractiveBentGender: Tomoki when he transforms into a girl using Ikaros' card.
** We later see that "she" is a GenerationXerox for "her" mother, both looks AND personality. Minus his mom's love of hot guys though.
* ArtisticLicenseMartialArts: Parodied at one point, when Mikako holds a sumo wrestling tournament...then decides that it'll be "American sumo," which is actually her code for "pro wrestling."
* AxCrazy: Chaos.
* {{Baka}}: Astraea and Tomoki's CatchPhrase for each other.
* BalancedHarem: Ikaros is in the lead, but Nymph and Sohara are also in the running, Astraea is a possible dark horse.
* BarackObama: In the 20th chapter, Obama cameos during the global emergency of...[[HilarityInZoos a zoo animal breakout]].
** YES WE CAN!
** He can be [[http://www.mangafox.com/manga/sora_no_otoshimono/v11/c044/38.html seen again]] in chapter 44.
* BeachEpisode: Set at Mikako's private DesertedIsland. [[spoiler:Finally subverted; everything was a play of Mikako and her father to punish Tomoki and collect good embarrassment material.]] Episode six is a more traditional beach episode.
** Actually the author has them go to the beach a lot. Most of the time it's just setting up silly gags or tournaments to torture Tomoki. Others are more serious.
* BeamSpam: [[spoiler:Ikaros' Artemis weapon system.]]
* BearsAreBadNews: After his house explodes, Tomoki attempts to stay at Sugata's place, which he finds very difficult to do. To live there, one must be prepared to fend off bears.
* BeautyBrainsAndBrawn: The three first-generation Angeloids.
* BeCarefulWhatYouWishFor: Not only does Ikaros tend towards being a LiteralGenie, but once she's given a command ''that command can't be canceled''.
* BewareTheNiceOnes: Go ahead, threaten the main cast's loved ones. We dare you.
** Case in point, when Nymph's wings were ripped off, Tomoki looked ''pissed''.
* BeehiveBarrier: [[spoiler:Ikaros' Aegis defense system (a full version of this trope) and Astraea's Aegis-L defense system (more powerful, but only generates from the front.)]]
* BerserkButton: Ikaros goes into the TranquilFury kind whenever she thinks her watermelons are in danger. And God help you if you threaten Tomoki.
-->What are you going to do... to my Master?
** As of chapter 51, even Tomoki isn't immune to her rage if her watermelons are in danger.
* BetaCouple: Eishiro and Mikako. Though the exact details are sketchy thus far, it's pretty clear these two have a past relationship and deep feelings for each other. Eishiro can frequently been seen protecting or using his body as a shield for Mikako when she's in danger of being hurt when things get serious. Mikako has a special pet name for Eishiro (Ei-kun), and gets crazy mad (more so than usual) when another woman is making moves on him. In the anime, Mikako flat out states that Ei-kun is the only man for her. Of course Mikako being Mikako, she's just as likely to try and kill Eishiro along with everyone else... but she'll probably take greater pleasure because it's him.
* {{BFG}}: [[spoiler:Both Ikaros' Apollon weapon system (a large bow that fires energy arrows) and the Hephaestus, which actually is a BFG seeing how it is an energy cannon capable of vaporizing mountains.]]
** [[spoiler:Oregano uses a gatling gun.]] And a pistol that accompanies the sound effect ''BoomHeadshot'' in Chapter 53.
* {{BFS}}: [[spoiler: Astrea's sword gets to stretch SOOOOO big against her fight with Chaos.]]
* BigDamnHeroes: [[spoiler:Tomoki, Ikaros, Sugata and Sohara save Nymph from the Harpies.]]
** And later, [[spoiler:Tomoki saves Nymph from Astraea when Minos turns them against each other.]]
** Later, [[spoiler:Yoshitsune saved Sugata after the world-destroying device activated.]]
* BigDamnVillains: An Angeloid specialized for water combat is going to attack Ikaros and Tomoki above the ocean, and water is an Angeloid's greatest weakness. Who saves the day? [[spoiler:Chaos. And [[FromBadToWorse she still really wants to show everyone her love.]]]]
* BigBad: By now, it's firmly established that Minos, The Master of Synapse is one.
* BigEater: Sugata.
* {{Bishounen}}: When he's not portrayed as super deformed, [[http://www.mangahere.com/manga/sora_no_otoshimono/v06/c025/22.html Tomoki is one of these.]] [[http://www.mangahere.com/manga/sora_no_otoshimono/v06/c026/31.html Seriously.]]
** Don't forget Sugata.
* BitchInSheepsClothing: Oregano, the new Angeloid introduced in chapter 52. Putting up a Ikaros-like demeanor as a facade, while bullying Nymph when Tomoki isn't around? Even pulling a WoundedGazelleGambit so Nymph becomes the villain in Tomoki's eyes? Of course, Mikako was the one who gave her the ability to speak in the first place ,so...yeah.
* BlatantLies: Ikaros uses this trope once to say the opposite of what she means. She mentions to Sohara that she lost a little weight, and when its clarified later, Sohara is horrified that she gained weight. Ikaros also mentions that Mikako is a very nice person, and when Mikako asks if Ikaros really meant it, the Angeloid this time pulls this trope off beautifully, with Mikako being none the wiser about it.
* BlindingBangs: Every inhabitant of synapse seem to have these.
* BlondeBrunetteRedhead: Astraea, Sohara, Ikaros.
* BookEnds: In the first and last episodes of the first season, Sugata tests one of his hangliders, each time saying quietly to himself, "The wind is picking up. And while I'm not too happy with its direction, it won't affect my takeoff."
** The last scene of the manga is the hill Tomoki first saw in his dreams.
* BoomHeadshot: [[http://www.mangareader.net/sora-no-otoshimono/53/18 Well...]]
* BrainwashedAndCrazy: [[spoiler: Hiyori in Chapter 39. She gets better.]]
* BreakTheCutie: Chapter 47 is completely devoted to breaking [[spoiler: Chaos. She finally realized what love actually is and attempted to go back to Synapse, but the Master blasts her with his strongest weapon. She survives and goes to Tomoki's house but accidentally overhears him say that Angeloids should leave and never come back. She starts crying, and decides that love is pain again. Then she dives to the bottom of the ocean. The entire time, she held on to the shoes Tomoki gave her.]]
** [[spoiler: What makes this even worse is that the scene then shifts to Tomoki sitting in the playground where he met Chaos, and he has a bunch of toys all set for her to play with.]]
** [[spoiler: And now she not only has all the memories of one of the kindest and most loving cast members all wrapped up in her head, but she just stabbed Tomoki through the friggin' heart. Seems like the author is dedicated to pushing the poor thing until she finally snaps so bad that she has to be put down.]]
* BreakingSpeech: Minos pulls this off in Chapter 55 towards Nymph and Daedalus, playing their emotions about how both of them desired Tomoki and Ikaros dying was the best for both of them. [[ShutUpHannibal Nymph tells him to STFU.]]
* BrickJoke: The handuffs and armour-removal cards from nearly the start of the series show up again when [[spoiler:[[http://manga.animea.net/sora-no-otoshimono-chapter-62-page-31.html Tokomi is getting civilian clothes for the Harpies]]]]
* BrownNote: Nymph's singing, in a sense. Not only is it bad beyond measure, it also managed to [[UpToEleven ''demolish language barriers'']] and ''[[SerialEscalation dent the Sun]]''.
* ButtMonkey: Tomoki. In later chapters this is even played for laughs.
** Nymph too, especially on recent chapters.
** Astrea's gets hit with this a lot.
* CallBack: [[ItMakesSenseInContext The Dong of Thunder]] returned in the most hilarious and awesome way possible in chapter [[http://www.mangareader.net/sora-no-otoshimono/53/37 53]], which apparently [[spoiler: is strong enough to destroy Ikaros' Aegis defense like garbage]].
* CantActPervertedTowardALoveInterest: Ikaros is about the only girl that Tomoki ''won't'' act perverted toward; in fact, he actively rebuffs her advances when she tries to come onto him. (He also won't act perverted towards Nymph, but that's because she's [[BuxomIsBetter not his type]], a source of [[ACupAngst considerable angst]].)
** This trope is backed up with [[spoiler:Tomoki's confession to Ikaros in chapter 53.]]
* CatchPhrase
-->'''Tomoki''': [[IJustWantToBeNormal Peace and quiet is the best.]]
-->'''Tomoki's manhood''': You called?
-->'''Tomoko''': [[SkinshipGrope We're all girls here!]]
* [[spoiler:CerebusSyndrome: While the series always has had a fair bit of moodswings, the later chapters really start to turn dark with the more serious moodswings coming in greater frequencies and major characters starting to [[AnyoneCanDie drop of like flies]].]]
* ChainsOfLove: Prominent between Tomoki and Ikaros after their first meeting.
* ChekhovsGun: [[spoiler:Sohara's increasing bustline is noted early on then revealed in the last chapter.]]
* ChekhovsSkill: [[spoiler:Swimming]], of all things.
* CheshireCatGrin: Mikako sports this as her default expression.
* TheChewToy: Tomoki, whenever Mikako comes up with a new scheme for her own personal enjoyment.
* ChivalrousPervert: Tomoki for all his many faults never takes advantage of the fact he has two "girls" that ''[[HappinessinSlavery want]]'' [[HappinessInSlavery to be his slaves]] and are quite willing to go pretty far to get him to be their master. To his eternal credit he is horrified by the idea and tries to teach them to be independent sentient creatures.
* ClothingDamage: Sohara in Episode 4, Tomoki more often. In fact the later chapters take this to Inukami-like levels, with Tomoki reduced to naked [[SuperDeformed chibi]] Tomoki every time he gets beaten up, flushed down the toilet and [[ButtMonkey so on]].
* {{Cloudcuckoolander}}: Sugata, who boldly eschews thinking in terms of reality in order to prove his theories.
** Despite this, he's also the cast's [[TheSmartGuy Smart Guy]]. On his second visit to Synapse, he could already outwit some combat Angeloids with planning that borders on omniscient. Later he manages to gain enough competency with the Angeloids' technology to repair one of their cards.
* CollaredByFashion: Ikaros and the other Angeloids.
* ColonyDrop: With flu medecine. [[MundaneMadeAwesome Ikaros as the pitcher]]. [[http://www.mangahere.com/manga/sora_no_otoshimono/v09/c051.4/8.html We wish we]] [[http://www.mangahere.com/manga/sora_no_otoshimono/v09/c051.4/9.html were kidding]].
* ComicallyMissingThePoint: In the movie, when [[ClingyJealousGirl Sohara, Nymph, and Astraea]] confront Tomoki about having a secret relationship with Hiyori, the first two ask him relevant questions regarding the possible relationship. Astraea, on the other hand, is upset that Tomoki gave food to Hiyori, rather than herself.
* CompanionCube: Ikaros carries around a watermelon for several episodes until Tomoki tells her that it's probably gone bad by then. A funeral is held for the departed fruit. Though she quickly finds another one. In the manga, this fondness of watermelons leads to her growing an entire patch of them.
** In fact, Ikaros has an affinity for anything large and spherical: watermelons, globes, Mikako's father's ''head''. They might represent unhatched eggs to her, as they seem to trigger her nurturing instincts.
* ContinuityNod: In ''forte'', Mikako mentions the former Pretty-kuns. [[spoiler:They all got lost or died in season 1.]]
* ConsummateLiar: Ikaros, after hearing that it's human to lie, ends up saying the opposite of whatever she thinks, which confuses everyone. At the end, she does tell the truth, but Sohara finds the truth not wholly flattering. Ikaros continues her lie to [[YakuzaPrincess Mikako]], because that's really the best option.
* CovertPervert: [[{{Hypocrite}} Sohara.]] In the manga, she had a dream where she was a very willing participant in Tomoki's cosplay fantasies. If that's not enough, the first episode of the 2nd season depicts this information in all of its glory, removing all doubt about Sohara's own twisted and perverted fantasies. In an episode of the first season, she talked about all the things she would want to do with Tomoki after possibly winning 10 million yen. One of them involved taking Tomoki into an outdoor bath with her, which would have been in an inn she made reservations for.
** Also, in the unaired episode (which was released as an OVA), when Tomoki asks Sohara what kind of dream did she have the night before, [[spoiler: she apparently dreamt of being at the altar with Tomoki as the groom. Then he leans in for (what many might think) a kiss, but ends up groping her breasts. Apparently, she doesn't mind if Tomoki does perverted things to her.. but ''only'' her and after they're married.]]
* CranialEruption
* CrazyPrepared: Ikaros in the omakes: "I have this for such cases..."
** Mikako: "By the way, I'm carrying a saw that's just right for cutting the lock..."
* CreepyChild: Chaos.
* CripplingOverSpecialization: The three main Angeloids.
** Ikaros is relatively smart and powerful, but lacks the ability to feel or comprehend emotions.
** Nymph is really intelligent and fast, but weak, so relies more on subtlety or non-physical attacks. She fares poorly in direct combat without support from Ikaros or Astraea.
** Astraea is a LightningBruiser, but is dumber than a bag of rocks, and is often outwitted by Tomoki and can barely feed herself.
* CryCute: [[http://www.mangareader.net/sora-no-otoshimono/53/32 Ikaros.]]
* CurbStompBattle: Oregano vs Nymph in Chapter 53. ''Holy shit''...
* CuteLittleFangs: Tomo in girl form. Just to add to his faking [[MoeMoe moe]].
* DarkIsNotEvil: The Satsukitane family. Sure, they're the local yakuza, their heir Mikako has a devious streak, and they have a habit of chopping off people's heads if they use their private hot spring, but their whole reason for existing is to protect that hot spring from being used by anyone else. That's because if anyone other than the Satsukitane family uses it, Sorami City will be hit by all sorts of natural disasters, such as famines, earthquakes and tornadoes. Other than the rather violent consequences they inflict on trespassers (which is implied to be something they find to be regrettable but necessary), the enforcers and the head of the family itself seem to be fairly affable people.
* DaydreamSurprise: Mixed with ImagineSpot and AllJustADream with Tomoki and Astraea imagining they are dogs looking for a good home. Long story short it ends with them licking each other then wondering what they were doing.
* DeadlyGame: Any competition run by Mikako.
* DeathIsCheap: Sometimes. Tomoki has been "killed" as a joke before, and the entire population of Earth was wiped out in the second episode, without long-term consequences, but other deaths (the Pretty-Kuns, for example) are permanent.
* DefeatByModesty: During the [[ProfessionalWrestling American Sumo Wrestling Tournament]], Tomoki wins his first and third fights by gluing himself to his opponent's breasts.
* DespairEventHorizon: [[spoiler: Pretty much ''everyone'' in Tomoki's UnwantedHarem hits this when Tomoki dies in Chapter 71; especially Chaos, who accidentally killed him when trying to defend herself from an [[UnstoppableRage enraged]] Nymph.]]
** [[spoiler: Subverted. Tomoki doesn't die, much to the relief of his harem, except Chaos doesn't know that, since she flew away after accidentally impaling him, so she's still at the DespairEventHorizon.]]
* DiedStandingUp: Parodied during the [[BlatantLies Sumo Wrestling Tournament]]. Tomoki takes numerous [[MegatonPunch Karate chops]] while being [[ShockAndAwe held against an electric fence]]. He stands back up, but the referee, Sugata holds up [[strike:Sohara]] [[PaperThinDisguise Masker Wrestler's]] hand in victory announcing that Tomoki [[FistOfTheNorthStar is already dead.]] [[UnexplainedRecovery He got better.]]
** [[spoiler: [[HeroicSacrifice Played depressingly straight with Yoshitsune towards the end of the manga.]] [[ResetButtonEnding Also gets better.]]]]
* DisproportionateRetribution: Usually happens with Sohara beating up Tomoki for the most trivial of things, such as when she [[ClingyJealousGirl gets jealous]] at Tomoki for merely teaching Ikaros how to swim. Or nearly getting beheaded for going into a bathing area. Or having the military called in on him for Ikaros freeing some animals at the zoo (who also seemed to target him as well for some reason). Poor guy just can't catch a break.
** I wouldn't call the chop for teaching Ikaros how to swim Disproportionate. If Pretty Girl #1 invites you to a Romantic Weekend for Two and you spend all your time with Pretty Girl #2, you may reasonably expect some blowback.
* DistaffCounterpart: Tomoki's mother with Tomoki. Sohara may be one for Tomoki's dad, as seen [[http://www.mangareader.net/sora-no-otoshimono/49/33 here.]]
* TheDitz: For all the power Astraea has, she was short-changed in intelligence. Nymph even says that they shouldn't worry when they found out that an Angeloid sent to kill Tomoki was her.
* DoAndroidsDream: It's something of a taboo for first generation Angeloids to dream, in part because they don't even sleep. It becomes something of an issue for Nymph when she starts becoming more human.
** Sugata eventually explains to her that dreams do not only happen during sleep, but it is also what you desire to happen.
* DodgeTheBullet: [[http://www.mangareader.net/sora-no-otoshimono/49/29 Tomoki and his mother]]
* [[DoesNotKnowHisOwnStrength Does Not Know Her Own Strength]]: All the Angeloids, but specially Ikaros. Really, when her try to be "close" to Tomoi ended burying his ''face in to the wall'' by the force of her cheek, you got a problem. Tomoki was not amused.
* DoubleStandard: In the manga, when Tomoki's mom shows up, turns out that she's as big a pervert as he is, but targets both girls and guys. She chases girls around, fondles their breasts, and proposes marriage to guys (her response to asking where her husband is a cheerful "I lost him somewhere"). She gets away with it, though, with the characters simply putting up with it in mild annoyance as opposed to the usual violent retribution Tomoki's actions receive... in fact, Tomoki gets beaten up ''for stuff his mom does''. The very end of the chapter does subvert it somewhat, showing Sohara's SpearCounterpart of Tomoki's father about to smack her, but his mother still takes far less abuse and doesn't get as beat-up-looking as he usually does.
* DoubleStandardAbuseFemaleOnMale: Sohara abuses this with Tomoki to no end. Although given his perverted nature, it's often justified.
** Played with in regards to Mikako. Yes, she does abuse Tomoki, but in her case she's actually ''meant'' to come off as a sadistic abuser. Its still all played for laughs though.
** This trope actually gets inverted with Tomoki's parents.
* DoubleStandardRapeFemaleOnFemale: {{Invoked}} by [[GenderBender Tomoko]] when ze pretends that what ze is doing is SkinshipGrope instead of just general perviness. "We're both girls, so it's okay!"
* DreadfulMusician: While Nymph's good at keyboard, her singing is... [[http://mangable.com/sora_no_otoshimono/chapter-44/31/ hoge hege hege.]]
* DrunkOnMilk: [[http://www.mangafox.com/manga/sora_no_otoshimono/v02/c009/15.html Sohara and Tomoki hilariously]] when Ikaros, under the belief that "to lie is human" tells them that she hates her and no longer wishes to be with him, repectively. [[TheSmartGuy Sugata]] [[LampshadeHanging mentions that they need to take care of themselves if they can get drunk on cola.]]
* DumbBlonde: Astrea, dear God, Astrea.
* EarlyInstallmentWeirdness: From Chapter 1 to chapter 10 Tomoki was more a generic harem guy, even with a "tragic" backstory, non-chibi form most of the time and while pervert, it was barely his deafening characteristic. It was after Nymph joined the cast and the appearance of the Master that the series got his tragy-comedy mecha battle style, nonsensical Family guy-ish slice of life that made it so loved.
* EmptyPilesOfClothing: After a satisfying day of having his every wish fulfilled by Ikaros, Tomoki jokes that the only thing left to do is 'take over the world'. The next day, after Ikaros's card decides that no one would accept his rule, the card erases everyone on earth, leaving all their clothes behind.
* EvenEvilHasStandards: In the movie, after Hiyori joins the New World Discovery club, Tomoki attempts to get her to leave by making her do seemingly humiliating things, such as sniffing panties. Oddly enough, Hiyori does everything he asks without shame or flinching. During the final event, he attempts to make her eat a plate of rice topped with some edible panties, which he apparently does on a regular basis as evidenced by the cook knowing what "his usual" meant. But as she begins, he starts feeling guilty about making her do such a thing. So he swipes the food, and eats it himself.
** This is actually shown right off the bat, when Ikaros first shows up. When she tells Tomoki she'll do anything he asks, being a pervert he asks her to strip, which she immediately starts to do. The moment she would actually show anything, he stops her and covers her with his jacket, [[ChivalrousPervert realizing that it would be wrong to take advantage of her]]. The fact that he has limits to his perversion basically kicks off the whole plot.
* EvolvingCredits: The ending changes every episode, and is based on something that happened during that episode.
* {{Expy}}: The creator seemed to re-use some of his character designs from ''Manga/WatashiNoMessiahSama''. Particularly comparable is Tomoki with Shinya (especially from the earlier volumes of ''Messiah-sama'') and Sugata with Shinya's Homeroom Teacher.
* TheFaceless: Daedalus
* FacePalmOfDoom: Used both humorously and seriously.
** Mikako's devastating wrestling move. But unlike most practitioners, this isn't done to kill, just to soothe her natural sadism.
** Ikaros uses this move on Chaos when she decides she's had enough of her crap.
* FamousLastWords: [[http://www.mangafox.com/manga/sora_no_otoshimono/v02/c007/28.html parodied?]]
* FantasticRacism:
** Minos, along with some Angeloids, regard humans as little more than bugs.
** Also Tomoki, surprisingly. At least, when anyone ships him with an Angeloid, he loudly protests that ''they have wings'' fer cryin' out loud! ''Wings!''
*** Tomoki is less racist and more unwilling to take advantage of the Angeloids' complete willing subservience. Notice his confession to Ikaros during the tournament arc, and [[spoiler:his reaction to ''Ikaros''' confession when she burns up to be less "I'm not reciprocating that!" and more "Why the ''hell'' are you telling me this ''now!''"]]
* FauxlosophicNarration: Some of the openings by Sugata.
* {{Fanservice}}
* FanDisservice: Tomoki from time to time.
* FeeFiFauxPas: When Tomoki tells the Angeloids to buzz of in one chapter, [[spoiler:Chaos]] was within earshot. [[BreakTheCutie She didn't take it very well]].
* FestivalEpisode
* FlexibleTourneyRules: Averted. Ikaros gets disqualified immediately when she uses homing lasers in a wrestling tournament.
* ForTheEvulz: Invoked by the Synapse Master, who seems to enjoy torturing Nymph and causing havoc for the human characters...usually Tomoki.
** Mikako also seems to enjoy utilizing this trope on other characters as well...usually Tomoki.
* FromBadToWorse: [[spoiler: At the end of ''forte'' episode 10, Chaos returns to the surface [[SheIsAllGrownUp with a brand new look.]] The latest chapter of the manga instead has Chaos absorbing a Marine Combat Angeloid, directly disobeying an order from her Master thanks to her self evolution program.]]
** Ikaros [[TakingYouWithMe barely manages to defeat]] [[spoiler:Melan. It looks like it's over for now...then about dozen or so Type Two Nymphs and Astraea show up.]]
** Chaos spends the entirety of a chapter [[spoiler: chasing Hiyori around to "eat" her. After Chaos manages to control herself and Hiyori sees how broken she is, she hugs her and it seems things will finally be ok for Chaos...and then Hiyori ''impales herself on Chaos' wings'' to make her understand hurting people is wrong, pushing her further down the DespairEventHorizon. Then, after she reveals herself as an angeloid to Tomoki, a [[RoaringRampageOfRevenge hell-bent on revenge]] Nymph starts attacking Chaos, who never fights back, remembering Hiyori's words. In the end, Tomoki gets ''impaled'' by Chaos' wing when he tried to stop the fight, most likely killed, causing Chaos to reach the deepest regions of the DespairEventHorizon]]. Damn...
* {{Gainaxing}}: Common, with the most frequent offenders being Ikaros and Astraea.
* GatlingGood: Ikaros, during the first summer festival. Also Oregano in Chapter 53.
* GeckoEnding: ''forte'' completely diverges from the manga starting from episode 11.
* GenderBender: "Tomoko", Tomoki's female form. Being GenreSavvy, he/she intentionally invokes numerous {{kawaii}} girl tropes, such as being an intentional {{dojikko}}, orchestrating tendencies of the LethalChef, and doing a LateForSchool CrashIntoHello, complete with PantyShot.
* GenerationXerox: We meet Tomoki's parents in chapter 49 and find it that Tomoki takes after his MOTHER.
* GenreSavvy: Mikako can instantly predict that Tomoki living with Ikaros will lead to hilarious NotWhatItLooksLike moments in front of Sohara. Even before that, Tomoki knows that bringing Ikaros home is going to dramatically alter his life as he knows it.
* GirlOnGirlIsHot: One of Tomoki's [[ImagineSpot fantasies]] has Nymph and Ikaros embracing.
* GlowingEyesOfDoom: Combined with RedEyesTakeWarning, this is how you can tell that [[spoiler:Ikaros is ready to kick ass as the "Uranus Queen," her fully powered battle mode]].
* GodivaHair: Mikako in the hot springs.
* GoofyPrintUnderwear: The impetus for the second episode. An ill-timed PantyShot of dog-print panties leads to Sohara wearing [[VaporWear nothing at all]] through the latent power of a card. The events of this ultimately lead to panties flying across the world like a flock of very strange birds.
* GroinAttack: Chapter 37. Ouch.
** Chapter 50 is even worse. MadeOfIron indeed.
** Episode 1 of ''forte'': Tomoki has Ikaros [[UpToEleven launch her Artemis]] at his "[[RagingStiffie money spot]]" in an attempt to get it down before Sohara shows up.
* GuiltyPleasures: Three words: ''FetishFuel Angels''.
** In-universe, Tomoki's porn and stolen panties stash.
* HappilyEverAfter: Perhaps the only happy end to a chapter for Tomoki is in the side chapter where Ikaros destroys his entire PornStash due to a misinterpretation, and she decides to make it up to him by gathering all the porn in town for him.
* HappinessInSlavery: Ikaros was created to serve her master and sees no problem with it, though Tomoki and the others attempt to break her out of this.
** On Nymph's end, however, it's shown that slavery is not at all a happy thing, and the point is driven in when she and Ikaros discuss smiling. [[spoiler:Though when she becomes a masterless Angeloid, she laments about not having a master, but is slowly growing out of it and starts expressing desires of her own.]]
** [[spoiler: Could still be played straight with Nymph. She actually begged for Tomoki to give her an order while trying to hack a BrainwashedAndCrazy Hiyori in chapter 40.]]
** Ikaros is shown to be breaking out of this habit by around chapter 30, [[spoiler:by disobeying Chaos!Tomoki's orders to kill Nymph. She proceeds to obey Chaos!Tomoki's orders to destroy herself afterwards, so her progress isn't far, but it's a start.]]
** It seems that the moral of the manga is herding over is that Tomoki must accept that Angeloids are ''Angeloids'' and not [[CaptainObvious humans]] and that they need a Master instead of the freedom he continually spews and accept them for who they are, not what they '''should be'''. Also, just because you had power over somebody in someway, doesn't mean you have to be [[WeHaveReserves a dick about it]].
* HaremSeries
* HehHehYouSaidX: Astraea does this a few times. Sometimes during comedic moments, sometimes during serious ones...
-->''Heehee! You said BUTT!''
-->''You said ass. Nice one.''
* [[spoiler: TheHeroDies: Tomoki gets [[KilledOffForReal killed]] trying stop Chaos and Nymph from killing each other in Chapter 71.]]
* HeroicSacrifice: Parodied with '''New Panties Robot''' in episode 5 of ''Forte''.
** Ikaros attempts to do one in the movie by containing a timed bomb with her shield, with her inside of it. However, Tomoki successfully manages to disable it before it explodes.
** [[spoiler:Yoshitsune in chapter 73.]]
* HilariouslyAbusiveChildhood: Tomoki's parents abandoned him on his 10th birthday, claiming he was a "splendid adult".
* HimeCut: Mikako.
* HoistByHerOwnPetard: When Sohara punishes Tomoki by wishing for any pair of panties that he even so much as ''looks at'' to instantly explode, he notices that she wasn't wearing any pants at the time, so he tricks her to stand up and walk away from her bedroom window by saying there's a giant bug on her wall. She realizes her mistake as soon as the panties she was wearing explodes on her.
-->'''Tomoki:''' ''Hehehe. Dumbass.''
* IdiotHair: Both Tomoki and Ikaros have one. In Tomoki's case, it's shown all the time while Ikaros' ahoge acts as an antennae that can sense when Tomoki is in danger. Since it wags around, her ahoge is also an example of ExpressiveHair.
* IllGirl: Sohara could not go to school before her adolesence due to chronic illness, and hence befriends the boy next door; Tomoki.
* ImageSong: Both seasons have them.
** LyricalDissonance: Mikako's character song, the title of which can be translated as "Princess Kill Them All", is a sweet, poppy tune with Mikako singing about what she wants. Death, destruction and ruling the Earth without mercy.
* InformedFlaw: Angeloids supposedly can't smile; although Ikaros does show that trait, Nymph is very obviously smiling on multiple occasions even ''in the episode'' where Ikaros and Nymph are discussing this, including ''flashbacks'' showing Nymph smiling. The problem seems to be that Nymph has never ''genuinely'' smiled, not that she has never physically ''done the action''.
* InnocentFanserviceGirl: Ikaros.
* IntercontinuityCrossover: The owner of the "fake" gun store in the FestivalEpisode is Zero Maschaitto, a character from another work by the same author, ''{{Judas}}'' as well as other characters appearing in the BeachEpisode. St. Peter also makes an appearance on the 10,000 Yen note in episode 1.
* IsItSomethingYouEat: Nymph, concerning wrestling. "Does pro wrestling taste good?"
* JerkWithAHeartOfGold: While it might be a bit far to call Tomoki a jerk, he definitely does have a nice heart. Even though his perverted antics border on sexual assault at times.
* JourneyToTheCenterOfTheMind: ''Forte'''s first episode is a dream jumping episode. Sohara's dream, in particular, stands out, though everyone's head is far from sane.
* TheJuggernaut: Chaos is a Moe TokenMiniMoe and is the most resilient Angeloid ever created. Hell, she shrugged [[spoiler: a direct attack of the mightiest weapon from Synapses... because she was to busy having an existancial crisis to notice]].
* KickTheDog: Minos. [[spoiler: The best example of this is when he forces Nymph to crush a small bird she made friends with, solely because it amused him.]]
* [[spoiler:KillEmAll]]: [[spoiler:until the last chapter]]
* LegendaryCarp: In the yo-yo breast fishing game Mikako dreamed up, Tomoki puts Sohara into this role. Needless to say, she's not happy with it.
* LightIsNotGood: Synapse and its inhabitants, ''especially'' the master. All the inhabitants wear togas and have angel-like wings, while the whole of Synapse has some sort of CrystalSpiresAndTogas air to it, all of which are likely meant to symbolize some sort of divine nature to them. However, their ideas of what is entertaining include mass destruction of the "downers" on the Earth's surface and threatening their "toys'" destruction while hearing them beg for their lives. Can be considered a variation of GodIsEvil, since they appear to represent Heaven.
* LimitedWardrobe: Sugata. During the PoolEpisode, he was asked why he was wearing his uniform, to which he responds that he doesn't have any other clothes.
* LookBothWays: [[spoiler:Hiyori]]
* LoopholeAbuse: Angeloids are unable to cancel any request by her master. That doesn't stop them from making it so that anything that goes wrong was AllJustADream.
* LovableSexManiac: Tomoki.
* LoveConfession: Hiyori gives one to Tomoki in the movie. Oddly enough, he doesn't seem to reject it, and spends the next scene fretting over it quite a bit.
** Nymph later nearly gives him one as well, but its cut short when the Angeloids sense something wrong.
** In chapter 53, [[spoiler:Tomoki confesses to Ikaros that he likes her before fighting her in the tournament.]]
* LoveDodecahedron: Parodied in the beginning of episode 10, where Mikako draws up a (mostly inaccurate) love chart...that even has her dog on it.
-->'''Sugata:''' ''Et tu, pooch?''
* LovePotion: Nymph does a variation of it, by using some {{technobabble}} to make Tomoki appear as every girls' ideal man. He decides to show off, but gets a GroinAttack as soon as Nymph decides to remove it.
* LoveFreak: Chaos did talk about love a lot...
* LoveHurts: [[spoiler: Chaos wanted to know what love was. Eventually, she decided that pain was love, and then she wanted to share love with the whole world!]]
** Affected Ikaros as well. While she doesn't go into ClingyJealousGirl mode, at times she seemed uncomfortable seeing Tomoki with another girl, and was unsure why she felt that way.
* MacrossMissileMassacre: Ikaros' Artemis weapon system is basically this.
* MadeOfIron: Comes in handy for a pervert like Tomoki. [[spoiler:Ikaros also shows various instances of this in a serious manner, all of which give Sugata reason to suspect her true nature as a weapon.]]
* MamaBear: Ikaros likes Tomoki, her watermelon farm and her friends. More or less in that order. She also happens to be [[PersonOfMassDestruction a tactical weapon of mass destruction]]. Try to guess how threatening any of them [[OhCrap usually works out]].
* ManlyTears: Quite a few instances during the comedy sequences. This chibified version of US soldiers [[http://www.mangafox.com/manga/sora_no_otoshimono/v05/c020/27.html is particularly humorous.]]
* MarshmallowHell: Astraea to Tomoki (accidentally).
** Ikaros to Tomoki (another accident).
** When Sohara came home in Episode 5, Tomoki ran into her and landed in ''Pie'' Hell.
* MarketBasedTitle: {{Funimation}}'s title for the show is ''Heaven's Lost Property''.
* MasterOfIllusion: [[spoiler:Chaos, the second generation Angeloid.]]
* MegatonPunch: Karate chop variation.
** We see a male on female version with Tomoki's parents for all the same reasons Sohara does it.
* MindControlEyes: [[spoiler:Hiyori's got them when she returns in Chapter 39.]]
* MoodWhiplash: Most of the chapters are focused on a sort of-SliceOfLife harem comedy, but there are pieces of heavy drama that sometimes comes out of left field. A good chunk of which comes from Synapse's master, or for dramatic effect, often corresponding with CerebusSyndrome.
* MsFanservice: nearly everyone qualifies.
* MundaneUtility: The ''first'' thing Tomoki asks for when he gets himself a smoking-hot Angeloid sex slave is...a billion dollars. Doesn't stick due to a ResetButton.
* NiceJobBreakingItHero: Tomoki says the phrase [[spoiler:"Angeloids should not come back"]] which is not meant to be taken seriously, but ends up [[spoiler: causing the literal minded Chaos who has just been blasted by her own master, to undergo a VillainousBreakdown. This breakdown leads her to come to the conclusion that "Love is Pain" and that she should acquire more 'intelligence' by eating others, which indirectly causes Hyori Kazane's death.]]
** [[spoiler: When Nymph finds out about Hyori's death (whom she just befriended), she duels Chaos. This leads Chaos to unintentionally killing Tomoki when he throws himself in between them. This causes Chaos's mind to go VillainousBSOD, made all the worse by her newly acquired conscience.]]
* NiceJobFixingItVillain: It's not exactly this, but [[spoiler: the Synapse Master didn't do himself any favors when he tried to scrap Chaos]].
* NiceGuy: Seriously, besides his Vouyerism and perverted episodes, Tomoki is the single, ''nicest'' being in the entire series and one of the nicest in anime. Its like what you get if you combined [[JesusWasWayCool Jesus]] with Howard Stern.
* NewTransferStudent: Ikaros and Nymph, by means of an UndeadTaxExemption card. It gets taken to the point where Ikaros ends up replacing one of the ''teachers''.
* NoKillLikeOverkill: During one episode of ''forte'', Nymph and Astraea are hungry, and the only food around is Ikaros' watermelon patch. Nymph notes to Astraea that "Once, a lot of bugs were flying around here. Alpha [Ikaros] blasted them all with her [[MacrossMissileMassacre Artemis]]
* [[spoiler: NoRomanticResolution: In the anime, due to a GeckoEnding. We've got another season coming, though.]]
* NotAllowedToGrowUp: No matter how many summer festivals pass, no matter how many characters refer to how many months have gone by, nobody has aged even a year from the series start to finish.
* OhCrap: In chapter 45, [[spoiler: Daedalus and the Master]] both react to [[spoiler: Chaos' return and newfound free will]] with utter shock and dread.
** End of chapter 51. [[spoiler: Once again Sugata effortlessly evades the harpies and returns home. [[http://www.mangahere.com/manga/sora_no_otoshimono/v09/c051/42.html Just one problem.]]]]
* TheOjou: Mikako.
* OmnicidalManiac: Minos has been messing with the the cast, making new and more powerful Ageloids and in general acting like a mad man because he wants to destroy "This Stagnant Reality".
** Heck, in that chapter he freely admits that being nice or even remotely humane, is just outright too difficult and unreasonable for him. He can only accept a literal killing solution to everything.
* OnceAnEpisode: Every episode has a ColdOpen with Sugata introducing the audience to a new concept related to the New World, usually working in a bit of history or science with it. Later episodes in the first season subverts his targeted audience towards Mikako, who happened to be present to listen and discuss his lessons with him.
* OurAngelsAreDifferent: They're super-powered, modified angels with an evil boss.
* PatientChildhoodLoveInterest: Sohara.
* PeekABangs: Chaos has this hairstyle (until she [[spoiler:is defeated and becomes good]]).
* PerpetualMolt: Like all anime angels, Angeloids seem to shed about one feather pillow's worth per flight.
* ThePowerOfFriendship: Present in all of its unabashed cheesy glory, alongside ThePowerOfLove.
* PowerPerversionPotential: Tomoki could instantly figure it out.
* PrettyFreeloaders: Nymph, and Astraea seems to do this as well, visiting Tomoki's house often for the free food.
* RapidFireFisticuffs: Sohara does a Karate-chop version against Tomoki, and Sugata engages in this with the bears that share his mountain home.
* ReallyGetsAround: Tomoki's grandfather (Tomozō Sakurai) claims he slept almost every girl in the world. Now he phrases this as that he only needs to sleep with 2,957,272,615 more woman to sleep with ''every woman in the world.''
** Total world population in 2010 was 6.9 billion. If half were women, then he's really ''only'' slept with about 493 million. Quite impressive, but not ''almost every girl''. They must blur together after the first hundred million or so.
* RealityWarper: Ikaros' initial abilities to Tomoki allow her to grant ''anything'' Tomoki wishes. Up to the point where she can make the entire second half of the episode AllJustADream. Tomo finds this quickly crosses over with BeCarefulWhatYouWishFor and BeCarefulWhatYouSay.
* RealSongThemeTune: Starting from episode two, every ending theme is an old song repurposed for the episode. The great majority are covers by the ''[=SoraOto=]'' cast, but one (episode five) is by the original singer (though the live concert has it covered by Sohara and Nymph's seiyuu).
* RedBaron: [[spoiler:Ikaros' title of the "Uranus Queen."]]
* RedEyesTakeWarning: Ikaros' eyes turn from green to red when she goes into protect mode for Tomoki.
* RefugeInAudacity: Flying panties (rendered in high quality CG) migrating through beautiful golden sunsets across the world like a flock of migrating swans? Yup, this show's got it.
** A couple of episodes later, [[ChekhovsBoomerang the flying panties come back]]. Sohara uses one of Ikaros' cards to make the [[MadeOfExplodium panties explode]] whenever Tomoki sees or touches one (just in case Tomoki doesn't throw away the panties like he was told to do). The thing is, Tomoki ''decorated the whole house with the panties''. Cue StuffBlowingUp, to the point where the whole house blows up completely. Oh and ''[[InstantAwesomeJustAddMecha mecha made out of panties]]'', designed to protect Tomoki's PornStash.
*** The best part of it? Tomoki uses the bombing panties curse [[HoistByHisOwnPetard to his advantage]]; [[spoiler:when Sohara explains any pair of panties will explode if he sees them, effectively locking him in his room, Tomoki simply changes the subject to a supposed bug in Sohara's room. Sohara stupidly turns around to look for the bug, exposing her own panties to Tomoki (exactly what he intended). Cue big explosion in Sohara's butt, and Tomoki's evil laugh while taking cover from Sohara's attack.]] Doubles as a CrowningMomentOfFunny.
** Episode 9 even crosses this line with the infamous ''Tomoki Tower'', almost taking the throne of the (even more infamous) ''[[PingPongClub Turtle Sequence]]''.
* RhetoricalRequestBlunder:
** The protagonist ends a bout of gratuitious wish fulfillment with the statement "Now all that's left is to take over the world!" in front of the LiteralGenie Ikaros. The next morning, she has concluded that since no one would recognize him as sovereign, the most efficient way of granting his wish is to make everyone disappear. As in, every human in the world. And so she does. This is the first episode. They get better.
** In the second episode, Tomoki starts shenanigans that leads to Sohara being unable to wear underwear. She beats him silly for it. When Ikaros shows up, Tomoki manages to croak "Panties..." She concludes that he wants panties, and makes every pair in the rear area fly off their owners and converge on Tomoki. This does not help at all.
* RuleOfFunny: Usually used to determine whether Tomoki is depicted as a {{Bishonen}} or SuperDeformed.
* SacrificedBasicSkillForAwesomeTraining: Ikaros has combat & intelligence maxed out at the expense of her emotions, Nymph has intelligence & emotions maxed at the expense of strength and Astraea has sacrificed intelligence for strength & emotions.
* SceneryPorn
* SexyBacklessOutfit: Nymph.
* SchoolFestival: A SlobsVersusSnobs type match with a rival academy takes place, with Tomoki and the main cast doing a FiveManBandConcert. It turns into very SeriousBusiness, thanks in no part to Mikako's intervention.
* ShipperOnDeck:
** Sohara ships Tomoki/Ikaros, in an IWantMyBelovedToBeHappy moment.
** In the final episode of the anime, Mikako tries to [[ShotgunWedding force Tomoki to pick a girl already]]. She is, however, mostly doing this to yank Tomoki's chain.
** Chapter 61 of the manga implies that Tomoki's father thinks of Sohara as his son's "most suitable" partner.
* ShoutOut: During Ikaros' undersea adventure in the fifth episode, Cthulhu can be seen in the background.
** Also, in episode one of the anime, when Tomoki stops time he says, "I am The World." A possible shout out to Dio's stand, who can stop time and is named The World, in ''Manga/JoJosBizarreAdventure''.
** The PoolEpisode has a quick shout-out to the [[VideoGame/{{Touhou}} Yukkuri]] meme (with Mikako being yukkuri-fied), complete with the "Yukkuri shiteitte ne!" CatchPhrase.
** Page 10 of chapter 41 has Tomoki and Astraea argument broken by Sugata... [[{{Naruto}} Tomoki can be seen clutching a snake while Astraea holding a frog]].
** Episode 9 of ''forte'' has at least two: One in the middle with [[Manga/WatashiNoMessiahSama three mini-Tarutarus]] and one in the form of {{Kinnikuman}}-esque mask in the end credits.
** In the OVA, Tomoki cannot self terminate at the pool and goes under a la T-800 style with a thumbs up (Terminator 2).
** Episode 11 of the anime features one to ''CalvinAndHobbes'' of all things with the transmogrifier.
** One to ''KingdomHearts'' when Tomoki is [[spoiler:[[http://manga.animea.net/sora-no-otoshimono-chapter-64-page-13.html stuck in a desert with the elder Harpy sister]] ]]
* ShowWithinTheShow: That would be ''Barnyard Sonata'', the soap that Nymph watches obsessively. It appears to take place on a ranch, and revolves around an illicit romance between the aristocratic Lady Umako and a burly farmhand. We don't get many details about other characters, although there is a powerful Count, and another character (not on screen) sounds as if he could be a talking horse.
* SlapstickKnowsNoGender: Tomoki occasionally hits Icarus (and even Astrea) on the head when they cause a lot of trouble for him. Like destroying parts of his house or flushing him down the sewer.
* [[spoiler: SlipknotPonytail:]] [[spoiler: When Nymph and Ikaros activate Pandora, they lose their pigtails/braid.]]
* SomethingElseAlsoRises: In episode 10 of ''forte'' when Ikaros sees Tomo making a kissing face through the TOMOKI Peeping Tom System she falls backwards and blushes heavily and her wings deploy.
* SoundtrackDissonance: A humorous version. Episode four's ending is a cover of a theme song to a war movie. Set against a backdrop of porn books.
* SpecialEditionTitle: ''forte'' begins with the first season opener, "Ring My Bell", [[RearrangeTheSong covered by Tomoki]] with the animation changed slightly.
* SpellMyNameWithAnS: Arguably a minor one. Was it Astraea or Astrea? Granted, those two is only a variation of the same name.
* SpiritualSuccessor: To ''WatashiNoMessiah-sama''.
* StatusQuoIsGod: Oh, so things are going well for Tomoki? Don't worry, it'll all come crashing down at the end of the episode/chapter.
* StealthInsult: Ikaros to Mikako. "You're a nice person".
* StudentCouncilPresident: Mikako. She has a bit of a devious streak, such as having life insurance set up to collect loads of money if Sugata fell to his death from hang gliding off the school building.
* StylisticSuck: "My Tingling Nipples"
* SuperDeformed: Tomoki, almost all the time. It's a rare instance where the viewer sees what he's ''supposed'' to look like. The rest of the cast occasionally joins in.
** Really, 90% of the time Tomoki is not deformed, he's being badass. Seeing Normal!Tomoki is [[OOCIsSeriousBusiness just as much an indication of seriousness]] as seeing Minos. When an entire episode goes by without him deforming, it's a WhamEpisode.
* SuperDrowningSkills: Basically all Angeloids, with exceptions being Ikaros, [[spoiler: Siren, and Chaos.]] Though it's due in part to their wings absorbing water, and making them too heavy to float. Also, on the human side is Sohara.
* SuperToughness: Tomoki. This guy make [[LoveHina Kentaro]] look like a whimp. Hell, he had taken enough damage to cripple Superman for crying out loud.
* SupportingProtagonist: Tomoki sort of fits this; although he's the center of the harem, and it's hinted at that he's TheChosenOne, the drama is largely surrounded the angeloids, and the one who's actually trying to solve the mystery of Synapse is Sugata.
* SuspiciouslySpecificDenial: [[http://www.youtube.com/watch?v=p1LhkptEw2k In the first episode of Season 2]], as the main characters are exploring each other's dreams, they come upon Sohara getting rather kinky with Tomoki. Sohara beats up Tomoki and Sugata (and tries to hit Mikako as well, but she dodges), then tries to pin these perverted dreams on Tomoki, but he keeps insisting these aren't his. She then decides to use a golf club to hit them away.
* SweetTooth: Nymph. She holds candied apples in especially high regard.
* TakingYouWithMe: Ikaros combines this with TakingTheBullet on a grand scale [[spoiler:with Melan, the second generation type theta, when Melan shoots Apollon Ikaros takes the shoot and then activates her Aegis trapping both her and Melan inside its blast. Saving Tomoki, Nymph, and Astraea and defeating that copy of Melan.]]
* TastesLikeFriendship: Tomoki does this twice, first with Nymph and a candied apple then later with Astraea and a full dinner at his house, along with a offer to feed her whenever she was hungry. Both instances of kindness eventually influenced their decisions to betray Synapse.
* TeenGenius: Sugata and Mikako. They're well-versed in first-year college maths even though both are only 15. They might as well qualify as [[TheAce The Aces]].
* [[ThanksForTheMammary Thanks For The Mamaries]]: Tomoki does this once in a while.
* TheTease: Mikako.
* ThrowTheDogABone: Chapter 53 "The World" finally give a respite for Tomoki in the "Tournament" fillers... [[MortalKombat AND IT IS GLORIOUS]].
* TheThreeFacesOfEve: There's two sets, so to speak.
** Tomoki's Angeloids form a set: Ikaros as the Wife (after she gained knowledge of everyday life, she leans towards this; also, she keeps a watermelon patch), Nymph as the Seductress (her attitude towards Tomoki after her liberation is leaning towards this), and Astraea as the Child (bumbling, ditzy, and quite innocent).
** The girls in the Exploration club forms another unit: Sohara (Wife; she keeps Tomoki in line), Satsukitane (Seductress; she masterminds a lot, if a quite insane one), and Kazane (Child; she is quite na´ve, and ultimately [[spoiler: thinks that this world is a game.]]).
* TimeStandsStill: One of the many powers Tomoki quickly abuses once he finds that reality can be altered on a whim. He also uses an invisibility cloak to peep on Sohara changing.
* TitleDrop: Episode 13 is called: "Sora no Otoshimono" or "Heaven's lost Property".
* TokenMiniMoe: Chaos and Nymph.
* TookALevelInBadass: Nymph initially loses a level when her wings are ripped out by the Harpies. She gains it back when her wings grow back thanks to the [[HappinessInSlavery power of slavery]] [[spoiler:and then she takes another when her wings upgrade this time thanks to the ThePowerOfLove.]]
* [[TournamentArc Tournament Chapter]]: Chapter 53.
* TrainingMontage: Astraea has one during the credits of the fourth episode in Forte.
** As does Tomoko in the credits of episode eleven.
* TransformingMecha: New Panties Robo. Fueled by erotic energy, he goes from motorcycle to robot, [[ABoyAndHisX Tomoki's loyal companion]].
* TricksterArchetype: Mikako.
* TurnedAgainstTheirMasters: Ikaros, Nymph and Astraea, thanks to the PowerOfLove and the fact that their human friends treat them as people rather than as crap. [[spoiler: Daedalus and the Master both fear that Chaos will do this now that she has free will.]]
* UndyingLoyalty: Seems to be where the series is going. While Tomoki has been trying to free "his" Angeloids, the desire to obey a Master (to have one) is so intrinsic and necessary for the Angeloids well being, that the only thing he can do is become a kind, loving Master... [[{{Ironic}} who orders them to be free.]]
* TheUnsmile: Not really as bad as the other examples of the trope but Ikaros' "smiles" are just her going "SFX: Smile" with a perfectly straight face.
* UnusualEars
* UpToEleven: [[InvokedTrope Invoked]] by Astraea in the dub. When Nymph [[ItMakesSenseInContext decides to shoot hot water up Tomoki's ass]] and turns up the temperature, she thinks to herself, "To Eleven!"
* ViolentlyProtectiveGirlfriend: While not his girlfriend per se, Ikaros will often stop anyone -- aside from Sohara it seems -- from hurting or attempting to hurt Tomoki.
* WalkDontSwim: Ikaros.
* WeWillMeetAgain: Inverted in episode 5 of ''Forte'', Eishiro mimics a certain WWII general of the Pacific (DouglasMacArthur in case you don't know), complete with his signature phrase "[[SurprisinglyGoodEnglish I shall return]]".
* WhamEpisode: Dear God, chapter 38. [[spoiler:A truck hits Hiyori and kills her, which simultaneously awakens her Synapse counterpart and wipes her friends' memories of her. Nymph then reveals that there are more people who are dreams of Synapse's inhabitants.]]
** As of Chapter 54, [[spoiler: a new Uranus Queen Appears from the Sky Master. Tactical Angeloid Type Theta: Ikaros Melan. She has hurt Tomoki pretty badly as well]]
** Chapter 55, [[spoiler: Nymph's new form and Ikaros has PANDORA as well]]
** [[spoiler: the end of chapter 45. Chaos is back. Be very afraid. Especially after a second episode in chapter 47.]]
** Chapter 70, [[spoiler: After spending half the chapter running away from her attacks to the point that she lost her weapon and one of her wings, Hiyori sacrifices herself so Chaos can understand that hurting people is wrong...Nymph finds Hiyori broken due to Chaos' attacks and goes UnstoppableRage while Chaos reveals herself to Tomoki as an Angeloid...]]
** Nothing can possibly top chapter 73, the purpose of the rule is revealed by ikaros to start the world over, and thats literally what it does, as everything on the entire planet begins to breakdown and disappear, eventually the planet itself wil be destroyed and remade, people, animals, buildings, entire countries are wiped away completely..
** [[FromBadToWorse It got worse]] in Chapter 71.[[spoiler: ''Tomoki gets [[KilledOffForReal killed]]'' trying to stop Chaos and Nymph from fighting and effectively pushed Ikaros, Nymph, Astraea, Sohara, and Chaos full force into the DespairEventHorizon... with Chaos being emotionally ''shattered'', leading her to run away and find Sugata, believing that he's the only person she can relate to, and knocks him out.]]
** In Chapter 77, it's revealed that [[spoiler:Daedalus, the creator of the Angeloids is -- and always has been -- the real Sohara Mitsuki, which explains how she knows all about Tomoki]].
* WhatIsThisThingYouCallLove: Nymph and Astraea know what it is but Ikaros and Chaos don't. All Ikaros knows is that it hurts her reactor.
** Later, Chaos is at the bottom of the sea and her reactor is hurting, just like Ikaros said, so this must be [[SarcasmMode love!]] And now she's going to go spread [[BloodyMurder "love"]] to everyone else.
* WhenSheSmiles: Ikaros.
** Its easy to forget that Tomoki is supposed to be [[http://www.mangareader.net/sora-no-otoshimono/53/42 quite the bishonen.]]
** But who hands down get the crown is [[spoiler: [[http://www.mangareader.net/sora-no-otoshimono/46/34 Chaos]]]]. I mean, its so cute that it should be illegal.
* WingedHumanoid: Ikaros and the other Angeloids.
* WondrousLadiesRoom: [[strike: Tomoki]] [[GenderBender Tomoko]] enters the girls' bathroom after a failed perversion attempt. The bathroom's cleanliness leaves her amazed.
* WoobieDestroyerofWorlds: Chaos.
* TheWorfEffect: The hyper-competent Sugata, who can beat the crap out of wild bears, survive faulty flying machines with barely a scratch and outsmart combat Angels with Batman-like preparations, gets [[CurbStompBattle curb-stomped]] by Mikako in a wrestling match.
** To a lesser degree, the Angeloids.
* WorldsStrongestMan: It's... dubious how canon or serious this are in the continuity, but if we take the Tournament arc at face value [[spoiler: Tomoki is the single strongest human ever, not only being capable of shrugging off Ikaros attacks (which brought down Astraea) but pierced Aegis with his [[ItMakesSenseInContext Dong of thunder]] like it was garbage, literally knocking her down for good]].
* YakuzaPrincess: Mikako.
* {{Yandere}}: [[spoiler:Chaos.]]
