!!Tomoki Sakurai
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Tomoki_Sakurai_Movie_1450.png]]
The local pervert and (therefore) all-around UnluckyEverydude. Lived alone in his home in Sorami Town until the Angeloids showed up.

->Voiced by: Creator/SoichiroHoshi (JP), Creator/GregAyres (EN); As [[GenderBender Tomoko]]: SakiFujita (JP), Creator/AlisonViktorin (EN)
----
* AccidentalPervert: Usually averted. But played straight when walking into Mikako's private hot springs was not something Tomoki ''meant'' to do, despite his general perversion.
* [[ChickMagnet Angeloid Magnet]]: Is there ANY Angeloid that hasn't some feelings for him, be they [[LoveInterest romantical]] or [[BigBrotherWorship familiar]]?
** Siren was killed before she could make contact with anyone other than Chaos. The Melan models seemed to be designed without any emotions at all. Everyone else is installed with Pandora [[spoiler:or, in Hiyori's case, knew him before becoming an Angeloid]]. [[ContrivedCoincidence Coincidence?]] [[WellThisIsNotThatTrope ...Probably]].
* ALessonInDefeat: In the anime, at least; after an attempt for SkinshipGrope on Astraea fails, [[AttractiveBentGender Tomoko]] is never used (directly) for Tomoki's peeping again. The only times she appears after that are (a) to get around ''Tomoki'''s refusal to participate in the "Yo-Yo Fishing" competition, (b) to install the "Tomoki Peeping System" pipes in female-only areas, and (c) as a test-run for the Quantum Converter in the last episode before converting to pool water. [[note]]Although he does go directly from Tomoko to pool water and back, he attempts no perversions between the pool incident and returning to Tomoki.[[/note]]
* ApathyKilledTheCat: Has absolutely ''no'' interest in where the Angeloids come from and how they and their powers work. [[spoiler: This gets him impaled on Chaos' wings.]]
* AttractiveBentGender: Tomoko, who intentionally invokes MoeMoe.
* CatchPhrase:
** "[[IJustWantToBeNormal Nothing beats peace and quiet!]]"
** As [[GenderBender Tomoko]]: "[[SkinshipGrope We're both]] [[DoubleStandardRapeFemaleOnFemale girls here!]]"
* ChronicHeroSyndrome: Doesn't matter if an Angeloid can kill a human just as easy as snapping a twig. If saving a friend means putting himself in danger, he'll do it. Astrea even lampshades this by saying that's why he can't learn about Chaos. If he did, he'd put himself in a dangerous situation again. Could also count as his FatalFlaw,[[spoiler: as that's what gets him killed in Chapter 71.]]
* {{Determinator}}: It doesn't matter if it's a perverted cause or a heroic one, Tomoki will see it through.
* [[spoiler:[[DidYouJustPunchOutCthulhu Did You Just Punch Out the Synapse Master?]]: Yes, and it was ''awesome''.]]
** Let's not forget the time he beat [[spoiler: Ikaros]] in a fair fight with his great [[ItMakesSenseInContext Thunder Wang!]]
* TheFakeCutie: As Tomoko, (s)he deliberately acts as {{Moe}} as possible.
* GenerationXerox: Towards his MOTHER! She even looks exactly like [[AttractiveBentGender Tomoko]]!
* [[IJustWantToBeNormal I Just Want A Normal Life]]: He was enjoying his peacefully dull existence just fine until all this happened. Now the poor perv can't go one day without some brand of insanity.
* IronButtMonkey
** [[spoiler: Not anymore. As of chapter 71, it seems Tomoki has finally been hit by something he can't recover from; in fact it looks like he's dead.]]
** [[spoiler: And he's back to normal again, thanks to Oregano. IronButtMonkey ''indeed''.]]
* JerkWithAHeartOfGold: Tomoki is a true friend who would do anything and sacrifice everything for the people he cares about. He would do only marginally less for perfect strangers who he's just met. He is also a pervert of such high caliber that his perverted antics, though PlayedForLaughs, sometimes cross into sexual assault.
** Here's an interesting example, when he and Sohara were "stranded" on an island for months, they were relatively happy with each other, despite the threat of being there forever. Tomoki even curbed his perversion completely just to take care of her! When the opportunity arose to take things... further, ''he was actually hesitant.'' Seriously, he accidentally touched her breasts and everything and he was '''nervous''' (no chibi mode in sight, either!). He may be the town's biggest pervert and loathed and hated by every single girl outside his harem because of it, but when it's time to be serious about affection and intimacy, he's serious.
* [[LikeFatherLikeSon Like Mother Like Son]]: His perverted character traits come from his mother.
* LovableSexManiac
* MoralityChain[[note]]AccidentalPun[[/note]]: Technically is one for all the Angeloids, but especially Chaos, who would obliterate the world were it not for her desire to be cared and loved by him.
* MrViceGuy
* NiceJobBreakingItHero: [[spoiler: Nice job doing your comedic routine of buzzing off Angeloids within earshot of [[CuteAndPsycho Chaos]].]]
* ThePeepingTom: Tomoki takes it to the extreme by having Ikaros stop time while he gallivants around the city, stripping down high school girls all around. He actually shrinks himself and sticks himself in the cleavage of another girl.
** And just [[UpToEleven the tip of the iceberg.]]
* [[HonourBeforeReason Perversion Before Reason]]: His first concern (when it comes up) is helping out his friends. His second, and by far his most prominent, is his perversion. Anything else, including self-preservation, comes a distant third.
** Notably, when pinned between Sohara's wrath and a ''toilet'', he decides to ''flush himself down the toilet''.
* RagingStiffie
-->'''Stiffie''': "You called?"
-->'''Tomoki''': "No I didn't!"
* SpannerInTheWorks: The [[BigBad Master of the Synapse]] is prone to just laugh off the Angeloids' attempts to fight off his latest invasion troops. As soon as Tomoki shows up, however, he always flies into uncontrollable rage. Justified, since Tomoki seems to be an [[ThePowerOfLove emotional powerhouse]] for his AmazonBrigade.
* UnstoppableRage [[RageAgainstTheHeavens Against The Heavens]]: [[spoiler: Tomoki's response to the Harpies being blown up because they went against their master's orders is... [[http://www.ultimateotaku.com/wp-content/uploads/2012/10/%C3%A9+%C3%A9t%C3%A9%C2%A6%C3%A9%C2%BF%C3%A9%C2%A6%C3%A9%C2%A6%C3%A9a%C3%A9%C2%A666_49.jpg just see it for yourself.]]]]
** [[spoiler: And when ''Ikaros'' died, his reaction was even worse.]]
* UnwantedHarem: Consisting of most of the Angeloids who stay on earth, plus Mitsuki. Good thing, too; no other girls want anything to do with a perv like him, and he knows it.

!!Sohara Mitsuki [[spoiler:AKA Daedalus]]
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Mitsuki_Sohara_Movie_9964.png]]
Tomoki's childhood friend who packs a mean karate chop. Lives next door from Tomoki.

->Voiced by: Mina (JP), Creator/TrinaNishimura (EN)
----
* BoobsOfSteel: She has the biggest breasts in the series (except possibly Astraea, who is said to rival her) and is the strongest human female yet shown (as proven in the "sumo" tournament).
* [[spoiler:BreastExpansion: Arguably invoked on Dedaelus's part.]]
* ClingyJealousGirl: She doesn't seem too fond of Tomoki showing interest in other girls.
* CovertPervert: If the first episode of ''Forte'' didn't show it.
* DistaffCounterpart: Towards Tomoki's father, at least in that they keep their respective Sakurai in line with karate chops. He even ships Sohara and Tomoki together because of it.
* GagBoobs: One chapter implies that they are the largest in town and still getting larger.
* [[MegatonPunch Megaton Karate Chop]]: Triggered via [[BerserkButton perversion]].
* LethalChef: in the manga, it's her sunny side up eggs (see chapter 41).
-->'''Tomoki:''' Eggs are... a symbol of existence. No... They are life itself. And so... these sunny side up eggs. (Pokes one with his fork causing a demonic spirits like odor shooting out scaring Astraea) SEE! It's a scent of death!
* MsFanservice: Often because she's the designated female ButtMonkey.
* NotSoDifferent: Turns out she's just as perverted as Tomoki. She's just better at hiding it.

!!Eishiro Sugata
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Eishiro_Sugata_Movie_9220.png]]
The head of New World Discovery club in Tomoki's school. An all-around smart guy who lives in the wilderness.

->Voiced by: Creator/TatsuhisaSuzuki (JP), Creator/EricVale (EN)
----
* AdjustingYourGlasses: Most of the time.
* {{Badass}}: While he doesn't show it off often, he does do some pretty awesome stuff, such as fighting a with a bear, bare-handed. And winning.
** See {{Determinator}} below.
* ClubPresident
* {{Determinator}}: Okay, so we've got Sugata, hiding behind a pole, in Synapse, outside the dome full of angels, guarded by the Harpy Twins. He has ''no idea'' how the hell he's going to get in there without the Angeloids noticing. But when [[spoiler:Hiyori starts to disappear from his memories]], he says "Screw it", charges towards the entrance, the Harpy twins notice, ''he shoves them aside and tells them to move it''. '''BadAss'''.
* DitzyGenius: Strong {{Cloudcuckoolander}} tendencies, masking a mind that runs like a Swiss watch.
* GunKata: With Miyako during the shootout in the first festival.
* LimitedWardrobe: His school uniform is the only outfit he owns.
* {{Megane}}
** StoicSpectacles: occasionally also ScaryShinyGlasses.
* MrExposition: He usually gives a history lesson which usually has some relevance to that episode's plot.
* OnlySaneMan: Sometimes he's the only one who doesn't overreact to everything going on.
* [[spoiler:TakeAThirdOption: Despite sincerely wanting a new world, he was able to provide Tomoki with a way to reset things.]]
* TheUnfavourite: ''BIG TIME.'' [[spoiler: Apparently, he and his big brother were pretty tight when he was a little kid; they'd make all kinds of planes, big and small, to send into the sky. One day, though, they got into a pretty pointless argument. His brother shrugged it off immediately, but Eishiro was still angry. Therefore, he half-assed his inspection of their latest glider out of spite. Naturally, of all days for something to go wrong, it had to be then...and it got him killed. When their parents found out it was his fault, they quickly learned to hate him, and when his baby brother was born, Eishiro was all but disowned... and they will ''never'' forgive him.]] There is a reason why talking about his family is such a sensitive subject, and why he wanted a new world so damn badly.
* TheWorfEffect: The prime example in this series.

!!Mikako Satsukitane
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Satsukitane_Mikako_Movie_1702.png]]
The local YakuzaPrincess, whose sadistic streak can match any psychopath. Also the student council president.

->Voiced by: Creator/AyahiTakagaki (JP), Creator/JamieMarchi (EN)

* CoolBigSis: To Tomoki and Sohara.
* CurtainsMatchTheWindow
* CuteAndPsycho
* GunKata: With Sugata during the shootout in the first festival.
* FacepalmOfDoom: Her FinishingMove as a wrestler. Nymph calculates it deals 400 kilos per square inch.
* HeroicComedicSociopath: Her CuteAndPsycho tendencies and murderous nature are 100% PlayedForLaughs.
* KarmaHoudini: She ''never'' gets any sort of true comeuppance for her misdeeds.
* LackOfEmpathy: PlayedForLaughs. She's so bad, she's even failing Ethics class. Her answer to any moral dilemma is simply a cheerful, "I kill everybody."
* ManipulativeBitch: But, of course.
* PerpetualSmiler: [[DissonantSerenity Even when enraged...]]
** If she ain't smiling, something's wrong... [[OOCIsSeriousBusiness and it isn't being]] PlayedForLaughs.
* PurpleEyes
* ShipTease: With Sugata, calling him by the [[AffectionateNickname Ei-kun]], and being the prime recipient of her PetTheDog moments. [[spoiler: And then there's the [[TearJerker absolutely heartbreaking moment when she calmly holds his dead body while resting under the trees...]]]]
* TokenEvilTeammate: She often performs this role to get things she wants done, such as forcing Tomoki to join the New World Discovery club largely against his will. She also sponsors a gun shooting contest using very realistic looking toy guns, as well as a boys vs girls snowball fight, and a wrestling tournament in which she tries to punish Tomoki, and oddly enough, Sugata.
* TricksterArchetype
* VaporWear: Blink-and-you'll-miss-it glimpse in Episode 10.
* YakuzaPrincess
* {{Yandere}}: Whoo boy, don't even ''think'' about dating or calling Eishiro Sugata "Ei-kun". Horrific things will happen.
* [[YouGottaHaveBlueHair You Gotta Have Purple Hair]]

!!Hiyori Kazane

->Voiced by: Creator/YokoHikasa (JP), Creator/ColleenClinkenbeard (EN)

* WalkingSpoiler: [[spoiler:She gets resurrected as the Angeloid, Zeta.]]
* [[spoiler: WingedHumanoid: When awakened in Synapse, she has ordinary angel wings. Once Minos converts her into an Angeloid, they become somewhat mechanical in nature.]]

!!Tomozo Sakurai
Tomoki's late grandfather. He is very influential in his decisions... not in a good way, mostly.

->Voiced by: Hiroshi Iwasaki (JP), Bill Flynn (EN)

!!Tomoyo Sakurai
Tomoki's mom. She and Tomoki's dad left for a world trip when Tomoki turned 10.
----
* AnythingThatMoves: Though she did marry Tomoki's dad, perversion for busty women is passed down through her side of the family. Including her.
* BiTheWay: Likes both men and women; especially the women.
* GroinAttack: [[http://raw.senmanga.com/Sora_no_Otoshimono/67/22 Here]], coupled with GetAHoldOfYourselfMan.

* [[CallingTheOldManOut Calling Sugata's Old Man Out]]
* CovertPervert: With some Tomoki influence.
* CulturedBadass: He's quite skilled with a violin, and is a lover of orchestras... And is not afraid of [[spoiler:driving into the household of one of Sorami's richest families with a firetruck followed by dishing out some verbal asskicking, calling out said family on their treatment of their elder son]].

* [[spoiler: DiedStandingUp]]
* [[spoiler: HeroicSacrifice: He buys time for Sugata to rewrite Rule, which ultimately saves the world.]]
* IronButtMonkey: If you can come out of [[http://raw.senmanga.com/Sora_no_Otoshimono/67/13 this]] like nothing has happened, then you certainly qualify.
* JerkWithAHeartOfGold: He's arrogant, condescending, and all in all a bit of a prick. He's also a good friend and when it comes down to it, he knows what's right and what's wrong and will unflinchingly do what's right.
* WhatHappenedToTheMouse: His crush on Ikaros is never brought up again in his later appearances.

Angeloids: Combat-oriented gynoids created by Synapse. They have a ThemeNaming derived from Greek mythology, down to their weapons.

[[folder:Angeloids]]

!!Ikaros
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Ikaros_Movie_5790.png]]
The first Angeloid known in the series. Her formal designation is ''Type Alpha, Strategic Battle-class Angeloid''

->Voiced by: Creator/SaoriHayami (JP), Creator/BrittneyKarbowski (EN)
----
* AbsoluteCleavage
* TheAce: She was Synapse's greatest weapon.
* BadassAdorable
* BerserkButton: Don't touch her master, her friends, or her watermelons. Also her little toy with the pop-off head.
* BettyAndVeronica: The Betty to [[PatientChildhoodLoveInterest Sohara]]'s Veronica, in a rare variation, where the Betty arrives after the Veronica.
* CryCute
* CutenessProximity
* DefrostingIceQueen
* [[spoiler:DyingDeclarationOfLove: To Tomoki as she dies in the final chapter. She gets better, but doesn't get a proper answer.]]
* EmotionlessGirl: At first. Even now, she can't show many emotions, but little by little, she's opened up to Tomoki and the rest of her friends.
* ExtremeDoormat: She gets (slightly) better.
* [[spoiler:GoOutWithASmile: In the final chapter, she dies smiling to Tomoki while confessing her love for him. She gets better.]]
* IdiotHair: It seems to warn her when Tomoki is in danger.
* LiteralGenie
* MeaningfulName: [[spoiler:In Chapter 76 she lives up to her name, as her wings catch on fire and burn up while she is carrying Tomoki in midair. It's stated this was a self-destruction system put in place in case she ever got too close to Synapse without permission.]]
* MessyHair
* MulticoloredHair: Her side bangs along with her messy hair and that innocent face of hers increases Ikaros's cuteness level by over 9000!!
* NamedWeapons: She has the most so far. '''[[MacrossMissileMassacre Artemis]]''', '''[[EnergyBow Apollon]]''' (her bow, whose power is said to be enough to annihilate a country), '''[[ExactlyWhatItSaysOnTheTin Ae]][[BeehiveBarrier gis]]''', and '''[[{{BFG}} Hephaestus]]'''.
** The anime traded out Hephaestus for the '''Uranus System''', a giant battleship/Mobile Armor that seems to be generated ''from the sky itself''.
* PersonOfMassDestruction: There's a reason that Synapse wants their Lost Property back.
* RapunzelHair: You normally don't really notice it due to her braids (which go behind her wings), [[spoiler: [[http://www.mangahere.com/manga/sora_no_otoshimono/v13/c056/2.html but when she activates her Pandora system...]]]]
* RedBaron: She is nicknamed ''The Uranus Queen''.
* ReiAyanamiExpy: An obedient and submissive Angeloid with an extremely little display and understanding of emotions, but comes to slowly warm up thanks to her feelings for the main character. Her ShortHairWithTail also looks like Rei's bob haircut at first glance.
* ShortHairWithTail
* SignificantGreenEyedRedhead
* SugarAndIcePersonality
* SuperDrowningSkills: Subverted in that she can't swim due to her wings being really heavy when wet, but she can't drown either. Nor does oceanic pressure seem to affect her.
* SuperSpeed: Has the highest top speed of all the Angeloids. Astraea beats her in acceleration and agility, however.
* TurnedAgainstTheirMasters
* ViolentlyProtectiveGirlfriend: While not Tomoki's girlfriend per se, she is VERY protective of her master. And that's [[SubordinateExcuse not just because he is her master...]]
* WhatIsThisThingYouCallLove: Unlike Nymph [[spoiler: and Astraea]], Ikaros has only an inkling of what the pain in her reactor means. She compares herself to Chaos in this respect.
* WingedHumanoid: She is the only Angeloid with a [[spoiler:complete]] Variable wing core, which allows her to [[YourSizeMayVary adjust the size of her wings as needed]].
* ZettaiRyouiki

!!Nymph

An Angeloid sent from Synapse to retrieve Ikaros, although she spent more time harassing her and Tomoki. Her formal designation is ''Type Beta, Electronic Warfare Angeloid''.

->Voiced by: Creator/IoriNomizu (JP), Creator/KaraEdwards (EN)
----
* ACupAngst: Made worse by the fact that her LoveInterest is a devout fan of breasts and she will be eternally flat according to her age device. [[spoiler: For extra measure, she's also the ''only'' flat-chested character in the entire series. Even Chaos' grows a bit as ''Forte'' and Chapter 70 show. Even the background female characters have a bigger chest.]]
* BigEater: Ate four pieces of cake in chapter 60 -- her's, Astraea's, Ikaros's, and Tomoki's.
* BigSisterBully
* BreakTheCutie: She gets stomped and beaten on quite a bit early on.
* BrownNote: While it's debatable as to how truly destructive it is in canon, listening to her singing voice is rightfully described as ''Hell''. FridgeBrilliance when you remember that her [[CallingYourAttacks named attack]] is called [[MakeMeWannaShout Paradise Song.]] [[FridgeLogic Though her attack actually does less damage than just her singing.]]
* CovertPervert: Judging by how willing she is to watch pornographic movies with Tomoki and let him do perverted things. She also has very explicit daydreams when she sees Tomoki do perverted things.
* CripplingOverspecialization: As noted by the Master, there's not much use for an electronic warfare type against underdeveloped downers. [[spoiler: She's quite effective against Synapse's own tech, once Nymph evolves her abilities a bit, as shown in chapter 55 when she completely decimates an army of higher powered, more advanced Angeloids.]]
* CurtainsMatchTheWindow
* FantasticRacism: Has an extremely low opinion of [[PunyEarthlings "downers"]], at least at first.
* GirlishPigtails
* GoingCommando: [[http://www.mangahere.com/manga/sora_no_otoshimono/v09/c051.3/6.html Looks that way.]]
* HeelFaceTurn: While she was never overtly evil, she was working under the orders of her master, who [[YankTheDogsChain treated her like absolute garbage]]. Then comes Tomoki and his friends, who treat her really well without any ulterior motives.
* {{Jerkass}}: At first. Even after her HeelFaceTurn and CharacterDevelopment, her treatment of Astraea borders on this.
** Sadly, this is why Oregano hates her.
* MakeMeWannaShout[=/=]BreathWeapon: Her Paradise Song attack.
* TheMillstone: True to her complex about being junk, a lot of problems in the series could have been avoided if Nymph wasn't around to cause them.
* NamedWeapons: Not a weapon ''per se''. She had the Fundamental Particle Jamming System, '''Aphrodite'''.
* RapunzelHair: Has some really long pigtails. [[spoiler: [[http://www.mangahere.com/manga/sora_no_otoshimono/v13/c055/37.html Activating her Pandora System just makes it even easier to notice.]]]]
* RealityWarper: Ikaros can affect reality with her cards, but Nymph can ''hack reality''.
* ShanaClone: Small? Check. RapunzelHair? Check. Grade A ZettaiRyouiki? Check. Fond of sweets? Check. Aggressive and condescending {{tsundere}}? Check.
* SweetTooth: Again, ate FOUR pieces of cake.
* [[spoiler:TakingYouWithMe: Uses her self destruct in an attempt to take out Minos.]]
** [[spoiler:SenselessSacrifice]]: [[spoiler:though it does destroy the Zeus core and allow Tomoki access to Synapse]].
* TokenMiniMoe: Doomed to be eternally UsefulNotes/{{Pettanko}} at an old age judging from a age device in an extra chapter.
* {{Tsundere}}
* TurnedAgainstTheirMasters: [[spoiler: Took a group effort to break her chain.]]
* UnstoppableRage: [[spoiler: After Chaos kills Hiyori.]]
--->[[spoiler:'''Nymph''': ''I'm going to kill you... I'll kill you... I'll kill you...!'' '''[[BerserkerTears I'll kill you!]]''' '''''[[RoaringRampageOfRevenge CHAOS!!]]''''']]
* WingedHumanoid: She possesses Stealth model wings, which are capable of disappearing if needed. However, she was wingless for a short duration after her encounter with the Harpies.
* TheWorfEffect: She got counter-hacked while fighting Zeta, while she is supposed to be the Angeloid ''made'' for such warfare.
** Though to be fair, the Master of Synapse had actually planned for Nymph trying to hack Zeta and took countermeasures.
** She also trounced Zeta's hacking after she got encouragement from Tomoki. Nymph tends to suffer from self-doubt.

!!The Harpy Twins
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Harpy_1355.jpg]]
Angeloid(s) sent from Synapse to kill Ikaros and retrieve her variable-wing core, although they are quickly relegated to guard duty. Their formal designation is ''Type Gamma, Ambush-purpose Angeloid''.

->Voiced by: Creator/MichikoNeya and MayaOkamoto (JP), Clarine Harp and Creator/StephanieYoung (EN)
----
* CripplingOverspecialization: Their High-Altitude wings are [[ExactlyWhatItSaysOnTheTin exactly like they sound]] - designed for high altitude. At lower altitudes, their flight capabilities are relatively worthless.
* InformedAttribute: Daedalus claims to have installed Pandora in all First-Generation Angeloids; the Harpy twins are the only ones not shown activating it.
* {{Jerkass}}
* NamedWeapons: Super Pyrotechnic Compression Firing Cannon, '''Prometheus'''.
** They also both have S. vibrate claw '''Nemea'''.
* ShamelessFanserviceGirl: The oldest doesn't see any shame in wearing all the Fetish costumes Tomoki picks out. [[spoiler: Until he picks up a bikini. She's absolutely mortified to see a piece of clothing that exposes her bellybutton.]]
** ComicallyMissingThePoint: When she's given a Playboy Bunny outfit, the first thing she does is compliment its free range of movement, then point out the ears' detrimental nature to her field of vision.
* [[ThoseTwoBadGuys Those Two Bad Girls]]
* WingedHumanoid: Their wings are High-Altitude model wings, which allow them to patrol maneuver about Synapse with ease when compared to other Angeloids.
* YouGottaHaveBlueHair: The younger sister has green hair, the older has red.

!!Astraea
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Astraea_anime_7554.png]]
The first Angeloid sent from Synapse with the purpose of killing Tomoki. Her formal designation is ''Type Delta, Regional Conflict Angeloid''.

->Voiced by: Creator/KaoriFukuhara (JP), Creator/CarliMosier (EN)
----
* AbsoluteCleavage
* AchillesHeel: She has no long-range attacks.
* ApologeticAttacker: Astraea screams "I'm Sorry!" as she's about to kill Nymph on Minos' orders.
* {{BFS}}: Chrysaor can turn into this. Chrysaor II can do this [[UpToEleven to the point that it's considered a ranged weapon]]. Chrysaor III is big enough [[SerialEscalation that it qualifies as a ranged weapon by default]].
* BigEater: She can eat a lot of food, and in at least one instance, it actually gets her in trouble as well (when she eats Ikaros' watermelons with Nymph, who then promptly blamed Astraea).
* BigShutUp: After Minos orders her to kill her friends one too many times, [[spoiler:she screams at him to shut up as she breaks her chain]].
* BoobsOfSteel: While she's not as powerful as Ikaros all-around, she is stronger in a purely physical sense, and her rack speaks for itself.
* BrainlessBeauty
** DumbBlonde
* ButtMonkey: Arguably even lower than Tomoki.
* CripplingOverspecialization: She is extremely effective in CQC but incapable of fighting at range, so if her enemies keep their distance and pummel her with ranged attacks, she's done.
* CrouchingMoronHiddenBadass
* TheDitz: Oh, God. Calling her a moron would be the understatement of the year. She can't even figure out basic addition, and she managed to fall behind in every subject on only her first day of school.
-->'''Ikaros:''' "You have three apples and four oranges. How many total pieces of-"
-->'''Astraea:''' "I eat all of them!"
-->'''Ikaros:''' "Ok, let's move on. Seven bananas-"
-->'''Astraea:''' "I EAT ALL OF THEM!"
** GeniusDitz: She's actually fairly clever (Of course, being an idiot, she nearly always misapplies this, leading to a lot of Rube Goldberg plots that don't actually work).
* DumbIsGood: She's a complete airhead and one of the nicest characters in the series.
* DumbMuscle: She's exceptionally stupid, but she's also exceptionally strong. [[spoiler:She's also the only angeloid shown to be strong enough to break her own chain. For comparison, breaking Nymph's chain took the combined efforts of Tomoki, Sohara, Miyako, and Sugata.]]
* DumbassHasAPoint: She occasionally notices things the others miss.
* ExtremeOmnivore: Rabbit pellets and fish bait are yummy to Astraea.
* FriendlyEnemy: [[spoiler:Before she broke her chain,]] she was extremely friendly with the main cast. [[spoiler:So friendly, in fact, that her switching sides can't even really be called a HeelFaceTurn.]]
* KickTheDog: An accidental case. She mocks Nymph for having no wings, trying to simply PokeThePoodle and not realizing beforehand how sensitive a subject it was. However she immediately regrets it afterwards upon seeing how hurt Nymph was.
* {{Leitmotif}}: The aptly named [[https://www.youtube.com/watch?v=bpzAAL_Bqrk Delta.]]
* LightningBruiser: She is the strongest and most agile of the first-generation Angeloids. She loses to Ikaros in terms of raw balls out speed, but in battle, where agility is just as important as speed, Astraea comes out superior.
* LuckilyMyShieldWillProtectMe: She carries the '''Aegis-L''' shield, which takes the form of a small round shield or a large buckler that has the ability to create a version of Ikaros' BeehiveBarrier that only faces one direction.
* NamedWeapons: The Photonic Oscillation Blade '''Chrysaor''' and the '''Aegis-L''' Shield (a version of Ikaros' Aegis that can only guard the front).
* NiceGirl: She's so nice that she can't help but give Tomoki a hand even when she was actually trying to kill him.
* PokeThePoodle: Some of her attempts to kill Tomoki fall under this, such as trying to poison him with a laxative.
* RapunzelHair
* SacrificedBasicSkillForAwesomeTraining: Well, not "training" ''per se'', but rather the details of her design: she was given overwhelming power at the expense of her intelligence. In other words, her incredible strength and speed in combat is offset by the fact that she's too dumb to even feed herself. In one instance, while fishing, she tries to eat the bait instead of using it to catch fish.
* TooDumbToLive[=/=]TooIncompetentToOperateABlanket: She doesn't know how to ''obtain food'', so she'll gobble up whatever's available when hungry, including rabbit pellets and fish bait (still on the line!).
** This is justified in both the manga and the anime when it is revealed that angeloids have three potential strongpoints: Emotions, Power, and Intelligence. Being first-gen, Astraea, Ikaros, and Nymph only have two of those three each. Ikaros [[EmotionlessGirl lacks emotions]] but is an [[GeniusBruiser extremely intelligent, if naive, powerhouse]]. Nymph has next to no combat ability but compensates with her ability to [[RealityWarper hack reality]], and is [[{{Tsundere}} easily susceptible to emotional mood swings]]. Astraea is a [[TheDitz comp]][[DumbBlonde lete]] [[DumbIsGood dumb]][[DumbMuscle ass]], but she's also a monster in close combat who can [[LightningBruiser hit hard, hit fast, and shrug off almost anything]] and is supposedly capable of overpowering even Ikaros when fighting up close, and [[TheHeart she has a wider and more stable emotional range than the other two combined]].
** [[spoiler:Chapter 75 is the worst instance of this, with her voluntarily sacrificing herself just so Chaos wouldn't die alone.]]
* TrainingMontage: She had one during the credits of the fourth episode in ''Forte''.
* UnskilledButStrong: According to Daedalus: "The reason I didn't add any processing capabilities to Delta... is because she doesn't need any." Astraea does note at one point that she's no match for Ikaros in a straight fight because Ikaros has skill and tactical acumen while Astraea only knows how to hit things really hard.
* WingedHumanoid: She bears Acceleration model wings, which allow her the speed/agility combo that she needs for close-quarters combat.

!!Chaos
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Chaos_Sora_No_Otoshimono_full_641028_8762.jpg]]
The first of the second-generation Angeloids, and also sent to Sorami City to kill Tomoki. Looks can be totally deceiving with her. Possessing no formal designation for her particular model, she is referred to as simply ''Second-Generation Angeloid, Type Epsilon''.

* BadHabits: Dresses up like a nun.
* [[spoiler: BigBrotherWorship]]: [[spoiler: Towards Tomoki.]]
* BreakTheCutie: If you don't feel bad for her at the end of chapter 47, you have no soul.
* CannibalismSuperPower: She claims to "eat" other Angeloids to gain their powers, though she's really just taking their cores.
* CreepyChild
* CuteAndPsycho
* DoesNotLikeShoes
* [[spoiler:EasilyForgiven: In the ResetButtonEnding.]]
* KnightOfCerebus: Every chapter with her in it is noticeably darker.
* LoveFreak: One of the most blatant examples in all of Manga and Anime. Even her character song is named "Ai wo Ageru", i.e. "I'll give you love". She doesn't know what love ''is'', though, but that doesn't stop her from being a freak about it.
* MasterOfIllusion
* MegaManning
* MeaningfulName
* NamedWeapons: Not a weapon ''per se'', but she had the '''Pandora System''', which enables her to evolve her capabilities.
** She also has the "anti-perception system '''Medusa'''" and "super-high-speed atomic vibration generator '''Chimera'''", [[spoiler:as well as stronger versions of Ikaros, Nymph and Astrea's weapons after assimilating the Melan models.]]
* NoSenseOfHumor: [[spoiler:Tragic example. The reason she killed Hiyori in the first place was because she walked in on Tomoki's skit of chasing the Angeloids out of his house and took it seriously.]]
* OmnicidalManiac: What makes it so heart wrenching, is that Chaos doesn't want to be the walking instrument of death and destruction she has become. Chaos wants to experience genuine love, but due to the means of her creation and various story events, she is truly unaware of how to interact with others without causing pain and murder. When Tomoki gives her the opportunity to experience loving compassion first hand, he becomes the bedrock of what little sanity she has left. After this event, Chaos' grabs for power are nothing more than an attempt to experience Tomoki's kindness again, yet ironically they further distance her from achiving that goal.
* PlotDrivingSecret: In the manga, Tomoki remains ignorant that Chaos is an Angeloid. He only knows her as an innocent little girl, and not an insane weapon of mass destruction. Her battles against the other Angeloids has always been either away from Tomoki or while he's knocked out.
** [[spoiler:As of Chapter 70, this is no longer true.]]
* [[spoiler: PhlebotinumOverload: Her multiple cores ultimately explode and killer her and Astraea.]]
* PoorCommunicationKills: [[spoiler:Hiyori and Tomoki.]]
* SurpriseParty: Has one in the special bonus chapter, though the guests were actually forced to go by Mikako.
* TragicMistake [[spoiler: Killing Tomoki.]]
* TroublingUnchildlikeBehaviour: While Tomoki tries to get the other Angeloids to be a bit more mature, everyone would agree that Chaos should cool down a little. She ''is'' a toddler after all.
* TokenMiniMoe [[spoiler: She gets a more mature body later on due to the Pandora System.]]
* WalkingSpoiler
* WhatIsThisThingYouCallLove: Eventually comes to the conclusion that ''pain'' is love. [[spoiler: She begins to truly understand it after her HeelFaceTurn.]]
* WingedHumanoid: She possesses an 'imperfect' version of the Variable wing core, which allows her to alter her wings similar to Ikaros. Chaos uses them like equipped blades, and she is capable of dismissing her wings entirely when needed. Due to the imperfections, her wings aren't organic-looking.
* YouGottaHaveBlueHair: Green actually.
* YouWillBeAssimilated: The biggest part of her power set is the ability to mimic the abilities of anything her wings pierce. [[spoiler:Doing this to Siren gets her underwater movement. Doing this to the Melan models gets her Second-Generation versions of all the weapons that Tomoki's Angeloids have]].

!!Zeta
[[spoiler: See Hiyori Kanaze]]

!!Siren
[[quoteright:180:http://static.tvtropes.org/pmwiki/pub/images/sirenangeloid_1620.jpg]]
A second-generation Angeloid which was sent to ambush Tomoki. Her formal designation is ''Type Eta, Underwater Combat Angeloid''.
----
* AbsoluteCleavage
* ImpaledWithExtremePrejudice: Hid in the water to ambush the Angeloids, [[spoiler:ends up getting killed from behind by Chaos.]]
* OurMermaidsAreDifferent: She's a [[NinjaPirateZombieRobot robot mermaid marine-combat type Angeloid]], thus ''averting'' the WingedHumanoid archetype of Angeloids and Synapse denizens.
* WingedHumanoid: Comes with being an Angeloid, however, her wings have more of a fin-like design to them to go with the mermaid design.

!!Oregano
[[quoteright:310:http://static.tvtropes.org/pmwiki/pub/images/310px-Oregano_anime_5567.png]]
A generic medical specialist Angeloid. One follows Sugata back from a dive game, after which she associates herself with Mikako. This... has consequences...
----
* {{Jerkass}}: Because Mikako was the one who gave her the ability to speak, she is this to Nymph because she used to routinely bully Oregano and her sisters back in Synapse. By forcing them to listen to her sing.

[[DoppelgangerAttack Tactical Weapon Angeloid]], type Theta, Melan. Equipped with a Variable Wing Core (Ikaros' wings), and mass-produced in [[PaintItBlack black-winged, black-haired]] mimicries of Ikaros, Nymph, and Astraea.
----
* AbsoluteCleavage
* TheAce: [[spoiler:Minos's]] greatest weapon(s).
* DoppelgangerAttack: In three flavors: Ikaros Melan, Nymph Melan, and Astraea Melan.
* EmotionlessGirl: Shows no emotion whatsoever, even compared to Ikaros.
* EvilCounterpart: Evil second-generation copies of the three first-gen Angeloid defectors, and sharing many of their traits.
* EvilTwin: To Ikaros, Nymph, and Astraea.
* MessyHair
* PaintItBlack: Black-haired, black-winged, and black-garbed version of Ikaros, Nymph, and Astraea.
* PersonOfMassDestruction: Oh, hell. Let's start a list.
** Ikaros Melan models have all the capabilities of the real Ikaros, in Second-Generation Angeloid statistics.
** Astraea is unable to pierce Ikaros Melan's Aegis [[note]]Chrysaor is supposedly capable of piercing Alpha's Aegis, and her own Aegis-L is much more resilient[[/note]].
** Nymph Melan models have hacking abilities strong enough that Beta has to activate Pandora in order for Aphrodite to counter them.
** Astraea Melan models are capable of shattering the Aegis-L that Delta carries.
* SuperSpeed: Has speeds that rival that of Ikaros.
* WingedHumanoid: They bear Variable wing cores - and unlike Chaos, these are ''perfect'' Variables. However, [[spoiler:Minos]] notes that Ikaros' Variable wing core has been nutured over time, thus making the ''wings'' inferior to Ikaros' own. Additionally, to differentiate the Melan models from their First-Generation counterparts, their wings are [[PaintItBlack black-feathered]].
