Heaven's Lost Property

In a quiet little town surrounded by the mountains, Tomoki Sakurai lives a peaceful life with his somewhat 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.

This manga was created by Suu Mikazuki (who previously wrote Watashi no Messiah Sama), and received an anime adaptation in the fall of 2009. A second season, Sora no Otoshimono forte, aired in the fall of 2010. The Movie (The Angeloid of Clockwork) was released in theaters in 2011, and a third season has been greenlit.

FU Nimation has licensed the first two seasons of the anime and the movie. You can find it here.

Tropes:
"What are you going to do... to my Master?"
 * The Abridged Series: Apparently...
 * Absolute Cleavage: Ikaros' and Astraea's Angeloid outfits.
 * Let's not forget Angeloid outfit. It's cut lower than either Ikaros' or Astraea's.
 * And now we have whose outfit is lower still.
 * Brief though her time in the series was, outfit also qualifies for this.
 * Abuse Is Okay When It Is Female On Male: Sohara abuses this with Tomoki to no end.
 * 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.
 * Accidental Pervert: For all Tomoki's intentional pervertedness, walking into Mikako's private hot springs was not something he meant to do.
 * Absurdly Youthful Mother: Tomoyo, Tomoki's omnivorous mother who he takes after almost identically. Aside from her hips, she looks the same age as Ei and Mikako and is actually shorter than them when not in chibi mode.
 * Actor Allusion: In a sense. Episode 4 of season 2 had the boys' side of the school referring Tomoki as OYAKATA-SAMA!! It was a rather common way to refer a lord in those times, but still.
 * The dub makes it a full-on reference. Amusingly, usage of "Your Lordship" prompts Tomoki to imitate Shingen.
 * Episode 10's dub has an accidental one to Beck, what with Tomoki and Eishiro on guitar in the band and all (Tomoki even gets to do some singing, though he's definitely worse than Koyuki).
 * Almost Kiss: Happens to Tomoki a few times in the series. With Nymph in episode 12 of the first anime and with Astraea in chapter 48 of the manga.
 * Alternate Character Reading: 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".
 * Alternate Continuity: The TV-and-movie-verse diverges from the manga at episode 11 of forte, and is now a separate continuity.
 * Amusing Injuries: 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 naked javelin.
 * Animated Actors: Episode 10's ending plays on this idea, by showcasing a montage of Hilarious Outtakes from past episodes.
 * Anything That Moves: As long it's a Bishonen or big boobed cutie, Tomoyo Sakurai, aka Tomoki's mother, will willingy jump their bones.
 * Art Evolution
 * Art Shift: 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.
 * Attack of the 50 Foot Whatever: About a dozen chickens, Sohara, and Tomoki in chapter 42. Hilarity Ensues.
 * Attractive Bent Gender: Tomoki when he transforms into a girl using Ikaros' card.
 * We later see that "she" is a Generation Xerox for "her" mother, both looks AND personality. Minus his mom's love of hot guys though.
 * Artistic License Martial Arts: 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."
 * Ax Crazy: Chaos.
 * Baka: Astraea and Tomoki's Catch Phrase for each other.
 * Balanced Harem: Ikaros is in the lead, but Nymph and Sohara are also in the running, Astraea is a possible dark horse, and No Romantic Resolution is entirely possible.
 * Barack Obama: In the 20th chapter, Obama cameos during the global emergency of...a zoo animal breakout.
 * YES WE CAN!
 * He can be seen again in chapter 44.
 * Beach Episode: Set at Mikako's private Deserted Island. Episode six is a more traditional beach episode.
 * Beam Spam:
 * Beauty Brains and Brawn: The three first-generation Angeloids.
 * Beehive Barrier:
 * Berserk Button: Ikaros goes into the Tranquil Fury kind whenever she thinks her watermelons are in danger. And God help you if you threaten Tomoki.

"Tomoki: Peace and quiet is the best.
 * As of chapter 51, even Tomoki isn't immune to her rage if her watermelons are in danger.
 * Beta Couple: 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:
 * And a pistol that accompanies the sound effect Boom Headshot in Chapter 53.
 * BFS:
 * Big Damn Heroes:
 * And later,
 * Big Damn Villains: 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?
 * Big Bad: By now, it's firmly established that The Master of Synapse is one.
 * Big Eater: Sugata.
 * Bishounen: When he's not portrayed as super deformed, Tomoki is one of these. Seriously.
 * Don't forget Sugata.
 * Bitch in Sheep's Clothing: 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 Wounded Gazelle Gambit 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.
 * Blatant Lies: 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.
 * Blonde Brunette Redhead: Astraea, Sohara, Ikaros.
 * Brainwashed and Crazy:
 * Break the Cutie: Chapter 47 is completely devoted to breaking
 * Brown Note: Nymph's singing, in a sense. Not only is it bad beyond measure, it also managed to demolish language barriers and [[Serial Escalation dent the Sun.
 * Butt Monkey: Tomoki. In later chapters this is even played for laughs.
 * Nymph too, especially on recent chapters.
 * Call Back: The Dong of Thunder returned in the most hilarious and awesome way possible in chapter 53, which apparently.
 * Can't Act Perverted Toward a Love Interest: 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 not his type, a source of considerable angst.)
 * Catch Phrase
 * Catch Phrase

Tomoki's manhood: You called?

Tomoko: We're all girls here!"

"Heehee! You said BUTT!
 * Chains of Love: Prominent between Tomoki and Ikaros after their first meeting.
 * Cheshire Cat Grin: Mikako sports this as her default expression.
 * The Chew Toy: Tomoki, whenever Mikako comes up with a new scheme for her own personal enjoyment.
 * Chivalrous Pervert: Tomoki for all his many faults never takes advantage of the fact he has two "girls" that want 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.
 * Clothing Damage: Sohara in Episode 4, Tomoki more often. In fact the later chapters take this to Inukami-like levels, with Tomoki reduced to naked chibi Tomoki every time he gets beaten up, flushed down the toilet and 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 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.
 * Collared By Fashion: Ikaros and the other Angeloids.
 * Companion Cube: 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.
 * Continuity Nod: In forte, Mikako mentions the former Pretty-kuns.
 * Consummate Liar: 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 Mikako, because that's really the best option.
 * Covert Pervert: 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,
 * Cranial Eruption
 * Crazy Prepared: 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..."
 * Creepy Child: Chaos.
 * Crippling Overspecialization: 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 Lightning Bruiser, but is dumber than a bag of rocks, and is often outwitted by Tomoki and can barely feed herself.
 * Cry Cute: Ikaros.
 * Curb Stomp Battle: Oregano vs Nymph in Chapter 53. Holy shit...
 * Cute Little Fangs: Tomo in girl form. Just to add to his faking moe.
 * Dark Is Not Evil: 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.
 * Daydream Surprise: Mixed with Imagine Spot and All Just a Dream 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.
 * Deadly Game: Any competition run by Mikako.
 * Death Is Cheap: 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.
 * Defeat By Modesty: During the American Sumo Wrestling Tournament, Tomoki wins his first and third fights by gluing himself to his opponent's breasts.
 * Died Standing Up: Parodied during the Sumo Wrestling Tournament. Tomoki takes numerous Karate chops while being held against an electric fence. He stands back up, but the referee, Sugata holds up Sohara Masker Wrestler's hand in victory announcing that Tomoki is already dead. He got better.
 * Disproportionate Retribution: Usually happens with Sohara beating up Tomoki for the most trivial of things, such as when she 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.
 * Distaff Counterpart: Tomoki's mother with Tomoki. Sohara may be one for Tomoki's dad, as seen here.
 * The Ditz: 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.
 * Do Androids Dream: 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.
 * Dodge the Bullet: Tomoki and his mother
 * 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.
 * Double Standard: 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 Spear Counterpart 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.
 * Dreadful Musician: While Nymph's good at keyboard, her singing is... hoge hege hege.
 * Drunk On Milk: 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. Sugata mentions that they need to take care of themselves if they can get drunk on cola.
 * Emotionless Girl: Ikaros.
 * Everythings Worse With Bears: 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.
 * Evolving Credits: 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 Watashi no Messiah Sama. Particularly comparable is Tomoki with Shinya (especially from the earlier volumes of Messiah-sama) and Sugata with Shinya's Homeroom Teacher.
 * Face Palm of Doom: 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.
 * Famous Last Words parodied?
 * Fantastic Racism: The Master of Synapse, along with some Angeloids, regard humans as little more than bugs.
 * Fauxlosophic Narration: Some of the openings by Sugata.
 * Fan Service
 * Fan Disservice: Tomoki from time to time.
 * Festival Episode
 * Flexible Tourney Rules: Averted. Ikaros gets disqualified immediately when she uses homing lasers in a wrestling tournament.
 * For the Evulz: 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.
 * Gainaxing: Common, with the most frequent offenders being Ikaros and Astraea.
 * Gatling Good: Ikaros, during the first summer festival. Also Oregano in Chapter 53.
 * Gecko Ending: forte completely diverges from the manga starting from episode 11.
 * Gender Bender: "Tomoko", Tomoki's female form. Being Genre Savvy, he/she intentionally invokes numerous Kawaii girl tropes, such as being an intentional Dojikko, orchestrating tendencies of the Lethal Chef, and doing a Late for School Crash Into Hello, complete with Panty Shot.
 * Generation Xerox: We meet Tomoki's parents in chapter 49 and find it that Tomoki takes after his MOTHER.
 * Genre Savvy: Mikako can instantly predict that Tomoki living with Ikaros will lead to hilarious Not What It Looks Like 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.
 * Girl On Girl Is Hot: One of Tomoki's fantasies has Nymph and Ikaros embracing.
 * Glowing Eyes of Doom: Combined with Red Eyes Take Warning, this is how you can tell that.
 * Godiva Hair: Mikako in the hot springs.
 * Goofy Print Underwear: The impetus for the second episode. An ill-timed Panty Shot of dog-print panties leads to Sohara wearing 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.
 * Groin Attack: Chapter 37. Ouch.
 * Chapter 50 is even worse. Made of Iron indeed.
 * Guilty Pleasures: Three words: Fetish Fuel Angels.
 * In-universe, Tomoki's porn and stolen panties stash.
 * Hannibal Lecture: The Master of Synapse pulls this off in Chapter 55 towards Nymph and Dadeus, playing their emotions about how both of them desired Tomoki and Ikaros die was the best for both of them...Nymph tells him to STFU.
 * Happily Ever After: Perhaps the only happy end to a chapter for Tomoki is in the side chapter where Ikaros destroys his entire Porn Stash due to a misinterpretation, and she decides to make it up to him by gathering all the porn in town for him.
 * Happiness in Slavery: 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.
 * Ikaros is shown to be breaking out of this habit by around chapter 30,
 * It seems that the moral of the manga is herding over is that Tomoki must accept that Angeloids are Angeloids and not 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 a dick about it.
 * Harem Series
 * Heh Heh You Said X: Astraea does this a few times. Sometimes during comedic moments, sometimes during serious ones...
 * Heh Heh You Said X: Astraea does this a few times. Sometimes during comedic moments, sometimes during serious ones...

You said ass. Nice one."

"Tomoki: Hehehe. Dumbass."
 * Heroic Sacrifice: Parodied with New Panties Robot in episode 5 of Forte.
 * Hey Its That Voice: Quite a few.
 * Tomoki is voiced by Soichiro Hoshi who also plays Kira Yamato, Sanada Yukimura, Keiichi Maebara, and Kei Kusanagi.
 * Tomoko, on the other hand, has the voice of a certain famous Leek Lover.
 * Shinichiro Miki is the Master of the Heavens. Which means he probably won against Aizen.
 * Imagine the quiet and shy Feldt as a devious, morally deficient and sadistic student council president.
 * Astraea's VA plays Tsukasa Hiiragi.
 * You will never look at Yui Hirasawa quite the same anymore, after looking at Chaos' brutality.
 * Hilariously Abusive Childhood: Tomoki's parents abandoned him on his 10th birthday, claiming he was a "splendid adult".
 * Hime Cut: Mikako.
 * Hoist By Her Own Petard: 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.

"Sugata: Et tu, pooch?"
 * Idiot Hair: 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 Expressive Hair.
 * Ill Girl: Sohara could not go to school before her adolesence due to chronic illness, and hence befriends the boy next door; Tomoki.
 * Image Song: Both seasons have them.
 * Lyrical Dissonance: 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.
 * Informed Flaw: Angeloids supposedly can't smile, but even in the episode where Ikaros and Nymph are discussing this, Nymph is very obviously smiling on multiple occasions.
 * Innocent Fanservice Girl: Ikaros.
 * Intercontinuity Crossover: The owner of the "fake" gun store in the Festival Episode is Zero Maschaitto, a character from another work by the same author, Judas as well as other characters appearing in the Beach Episode.
 * It Got Worse:
 * Ikaros barely manages to defeat
 * Journey to The Center of The Mind: forte's first episode is a dream jumping episode. Sohara's dream, in particular, stands out, though everyone's head is far from sane.
 * The Juggernaut: Chaos is a Moe Token Mini Moe and is the most resilient Angeloid ever created. Hell, she shrugged.
 * Legendary Carp: 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.
 * Light Is Not Good: 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 Crystal Spires and Togas 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 God Is Evil, since they appear to represent Heaven.
 * Limited Wardrobe: Sugata. During the Pool Episode, he was asked why he was wearing his uniform, to which he responds that he doesn't have any other clothes.
 * Look Both Ways:
 * Loophole Abuse: 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 All Just a Dream.
 * Lovable Sex Maniac: Tomoki.
 * Love Dodecahedron: Parodied in the beginning of episode 10, where Mikako draws up a (mostly inaccurate) love chart...that even has her dog on it.


 * Love Potion: Nymph does a variation of it, by using some Techno Babble to make Tomoki appear as every girls' ideal man. He decides to show off, but gets a Groin Attack as soon as Nymph decides to remove it.
 * Love Freak: Chaos did talk about love a lot...
 * Love Hurts:
 * Affected Ikaros as well. While she doesn't go into Clingy Jealous Girl mode, at times she seemed uncomfortable seeing Tomoki with another girl, and was unsure why she felt that way.
 * Macross Missile Massacre: Ikaros' Artemis weapon system is basically this.
 * Made of Iron: Comes in handy for a pervert like Tomoki.
 * Mama Bear: Ikaros likes Tomoki, her watermelon farm and her friends. More or less in that order. She also happens to be a tactical weapon of mass destruction. Try to guess how threatening any of them usually works out.
 * Manly Tears: Quite a few instances during the comedy sequences. This chibified version of US soldiers is particularly humorous.
 * Marshmallow Hell: 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.
 * Market Based Title: FU Nimation's title for the show is Heavens Lost Property.
 * Master of Illusion:
 * Megaton Punch: Karate chop variation.
 * We see a male on female version with Tomoki's parents for all the same reasons Sohara does it.
 * The Messiah: 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.
 * Mind Control Eyes:
 * Mood Whiplash: Most of the chapters are focused on a sort of-Slice of Life 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, who is a Complete Monster.
 * Also, how do you get from a major battle, to an attempted suicide attack, to this?
 * This Manga is full of Mood Whiplash, going from a girl fretting about how a boy sees her one panel to her getting hit by a car. The author really likes using this trope for drama.
 * The beginning of Forte episode 8.
 * Now with chapter 47 of the manga, we have... well, just read it. This author is disturbingly effective at jumping from theme to theme without feeling discongruous, and being damn good at writing all of them...
 * Chapter 54. It's nearly impossible to see coming.
 * Chapter 56. Just...chapter 56.
 * Ms. Fanservice: Sohara. Not by her own will, but she has spent 40% of the series without panties, so...
 * Mundane Utility: 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 Reset Button.
 * Nice Job Fixing It Villain: It's not exactly this, but.
 * Nice Guy: 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 Jesus with Howard Stern.
 * New Transfer Student: Ikaros and Nymph, by means of an Undead Tax Exemption card. It gets taken to the point where Ikaros ends up replacing one of the teachers.
 * Non Singing Voice: The dub averts this with episode 10's insert songs.
 * Oh Crap: In chapter 45,  both react to   with utter shock and dread.
 * End of chapter 51.
 * The Ojou: Mikako.
 * Omnicidal Maniac: The Master of Synapse 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.
 * Once an Episode: Every episode has a Cold Open 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.
 * Our Angels Are Different: They're super-powered, artificial beings with a Complete Monster for a boss.
 * Patient Childhood Love Interest: Sohara.
 * Peek a Bangs: Chaos has this hairstyle (until she ).
 * Perpetual Molt: Like all anime angels, Angeloids seem to shed about one feather pillow's worth per flight.
 * Pettanko: Nymph. It's a bit of a sore point for her.
 * The Power of Friendship: Present in all of its unabashed cheesy glory, alongside The Power of Love.
 * Power Perversion Potential: Tomoki could instantly figure it out.
 * Pretty Freeloaders: Nymph, and Astraea seems to do this as well, visiting Tomoki's house often for the free food.
 * Double Standard Rape Female On Female: Invoked by Tomoko when ze pretends that what ze is doing is Skinship Grope instead of just general perviness. "We're both girls, so it's okay!"
 * Rapid Fire Fisticuffs: Sohara does a Karate-chop version against Tomoki, and Sugata engages in this with the bears that share his mountain home.
 * Really Gets Around: 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.
 * Reality Warper: 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 All Just a Dream. Tomo finds this quickly crosses over with Be Careful What You Wish For and Be Careful What You Say.
 * Real Song Theme Tune: 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).
 * Red Baron:
 * Red Eyes Take Warning: Ikaros' eyes turn from green to red when she goes into protect mode for Tomoki.
 * Refuge in Audacity/Vulgarity: 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, the flying panties come back. Sohara uses one of Ikaros' cards to make the 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 Stuff Blowing Up, to the point where the whole house blows up completely. Oh and mecha made out of panties, designed to protect Tomoki's Porn Stash.
 * The best part of it? Tomoki uses the bombing panties curse to his advantage; Doubles as a Crowning Moment of Funny.
 * Episode 9 even crosses this line with the infamous Tomoki Tower, almost taking the throne of the (even more infamous) Turtle Sequence.
 * Rhetorical Request Blunder:
 * 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 Literal Genie 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.
 * Robot Girl: The Angeloids, of course, which explains their servile nature.
 * Rule of Funny: Usually used to determine whether Tomoki is depicted as a Bishonen or Super Deformed.
 * Scenery Porn
 * Sexy Backless Outfit: Nymph.
 * School Festival: A Slobs Versus Snobs type match with a rival academy takes place, with Tomoki and the main cast doing a Five Man Band Concert. It turns into very Serious Business, thanks in no part to Mikako's intervention.
 * Shout Out: 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 Jo Jos Bizarre Adventure.
 * The Pool Episode has a quick shout-out to the Yukkuri meme (with Mikako being yukkuri-fied), complete with the "Yukkuri shiteitte ne!" Catch Phrase.
 * Page 10 of chapter 41 has Tomoki and Astraea argument broken by Sugata... 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 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).
 * Shipper On Deck:
 * Sohara ships Tomoki/Ikaros, in an I Want My Beloved to Be Happy moment.
 * In the final episode of the anime, Mikako tries to force Tomoki to pick a girl already. She is, however, mostly doing this to yank Tomoki's chain.
 * Something Else Also Rises: 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.
 * Soundtrack Dissonance: 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.
 * Special Edition Title: forte begins with the first season opener, "Ring My Bell", covered by Tomoki with the animation changed slightly.
 * Spell My Name With an S: Arguably a minor one. Was it Astraea or Astrea? Granted, those two is only a variation of the same name.
 * Status Quo Is God: Oh, so things are going well for Tomoki? Don't worry, it'll all come crashing down at the end of the episode/chapter.
 * Stealth Insult: Ikaros to Mikako. "You're a nice person".
 * Student Council President: 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.
 * Stylistic Suck: "My Tingling Nipples"
 * Super Deformed: 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 just as much an indication of seriousness as seeing the Master of Synapse. When an entire episode goes by without him deforming, it's a Wham Episode.
 * Super Toughness: Tomoki. This guy make Kentaro look like a whimp. Hell, he had taken enough damage to cripple Superman for crying out loud.
 * Suspiciously Specific Denial: 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.
 * Sweet Tooth: Nymph. She holds candied apples in especially high regard.
 * Taking You With Me: Ikaros combines this with Taking the Bullet on a grand scale
 * Tastes Like Friendship: 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.
 * Teen Genius: Sugata and Mikako. They're well-versed in first-year college maths even though both are only 15. They might as well qualify as The Aces.
 * Thanks for The Mammaries: Tomoki does this once in a while.
 * The Tease: Mikako.
 * Throw the Dog A Bone: Chapter 53 "The World" finally give a respite for Tomoki in the "Tournament" fillers... AND IT IS GLORIOUS.
 * The Three Faces of Eve: There's two sets, so to speak.
 * Tomoki's Angeloids form a set: Ikaros as the Mother (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 (Mother; she keeps Tomoki in line), Satsukitane (Seductress; she masterminds a lot, if a quite insane one), and Kazane (Child; she is quite naïve, and ultimately ).
 * Time Stands Still: 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.
 * Token Mini Moe: Chaos and Nymph.
 * Took a Level In Badass: 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 power of slavery
 * Training Montage: Astraea has one during the credits of the forth episode in Forte.
 * Transforming Mecha: New Panties Robo. Fueled by erotic energy, he goes from motorcycle to robot, Tomoki's loyal companion.
 * Trickster Archetype: Mikako.
 * Turned Against Their Masters: Ikaros, Nymph and Astraea, thanks to the Power of Love and the fact that their human friends treat them as people rather than as crap.
 * Undying Loyalty: 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... who orders them to be free.
 * The Un Smile: 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.
 * Unusual Ears
 * ~Walk, Don't Swim~: Ikaros.
 * Violently Protective Girlfriend: While not his girlfriend per se, Ikaros will often stop anyone -- aside from Sohara it seems -- from hurting or attempting to hurt Tomoki.
 * Wham Episode: Dear God, chapter 38.
 * As of Chapter 54,
 * Chapter 55,
 * What Is This Thing You Call Love: 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 love! And now she's going to go spread "love" to everyone else.
 * We Will Meet Again: Inverted in episode 5 of Forte, Eishiro mimics a certain WWII general of the Pacific (Douglas Mac Arthur in case you don't know), complete with his signature phrase "I shall return".
 * When She Smiles: Ikaros.
 * Its easy to forget that Tomoki is supposed to be quite the bishonen.
 * But who hands down get the crown is . I mean, its so cute that it should be illegal.
 * Tournament Chapter: Chapter 53.
 * Woobie Destroyer of Worlds: Chaos.
 * The Worf Effect: 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 curb-stomped by Mikako in a wrestling match.
 * To a lesser degree, the Angeloids.
 * Winged Humanoid: Ikaros and the other Angeloids.
 * Wondrous Ladies Room: Tomoki Tomoko enters the girls' bathroom after a failed perversion attempt. The bathroom's cleanliness leaves her amazed.
 * Worlds Strongest Man: It's... dubious how canon or serious this are in the continuity, but if we take the Tournament arc at face value.
 * Yakuza Princess: Mikako.
 * Yandere:
 * is more Cute and Psycho. She has no idea what love is.
 * Mikako. NEVER let another woman try to date her Ei-kun. EVER.
 * You Have Outlived Your Usefulness: Nymph's master constantly threatens this on her, and often forces her to do something humiliating to slightly delay him utilizing this trope.
 * You Gotta Have Blue Hair: Nymph has blue hair, Ikaros has pink hair, and Mikako has purple hair. Eishiro has white hair though he is only a teenager. One of the Harpies has green hair.
