Mundane human beings living in the town of Sorami, somewhere in Japan. They are blissfully unaware of the presence of Synapse hanging over their heads (save for one guy)... until the Angeloids made their presence known.
The local pervert and (therefore) all-around Unlucky Everydude. Lived alone in his home in Sorami Town until the Angeloids showed up.
- Accidental Pervert: Usually averted. But played straight when walking into Mikako's private hot springs was not something Tomoki meant to do, despite his general perversion.
- Affectionate Nickname: Sohara calls him Tomo-chan.
- All-Loving Hero: While a pervert and having many, many flaws both in character and belief, Tomoki 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.
- Apathy Killed the Cat: Has absolutely no interest in where the Angeloids come from and how they and their powers work. This gets him impaled on Chaos' wings.
- Attractive Bent-Gender: His female identity Tomoko, who intentionally invokes Moe.
- Buxom Is Better: A devout fan of big breasts. This causes considerable A-Cup Angst in Nymph.
- Can't Act Perverted Toward a Love Interest: Tomoki acts perverted towards every female he came across, be it human or Angeloid, except Ikaros; in fact, he actively rebuffs her advances when she tries to come onto him. At one point, this is lampshaded when he was asked about it and he couldn't figure out why himself either.
- Catch Phrase:
- The Chew Toy: He usually gets smacked around as result of his perverted antics or ends up getting injured or abused in some other way, often from Mikako.
- Chick Magnet: Is there ANY Angeloid that hasn't some feelings for him, be they romantical or familiar?
- Chivalrous Pervert: Tomoki is a pervert of such high caliber that his perverted antics, though Played for Laughs, sometimes cross into sexual assault. However, he 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. He is also 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.
- 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.
- Chronic Hero Syndrome: 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 Fatal Flaw, as that's what gets him killed in Chapter 71.
- Conveniently Seated: He sits in the ever-popular window seat in class.
- Determinator: It doesn't matter if it's a perverted cause or a heroic one, Tomoki will see it through.
- Did You Just Punch Out Cthulhu?:
- He manages to punch out the Master of Synapse. And it was awesome.
- Let's not forget the time he beat Ikaros in a fair fight with his great Thunder Wang!
- Dirty Kid: Tomoki's parents left him to stay alone and travel around the world when he turned 10. Without parents, Tomoki lived with his grandfather, who inspired him and made him become an "ecchi, hentai" person with pervert quotes.
- The Fake Cutie: As Tomoko, (s)he deliberately acts as Moe as possible.
- Gender Bender: He occasionally uses a device to transform himself into a girl named Tomoko, so he can sneak into the girls locker room.
- Idiot Hair: Has a stray strand atop of his head.
- I Just Want to Be Normal: 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.
- Iron Butt Monkey: Not only does he get hit by megaton karate chops (one time being held up against an electrical fence), but also beam weapons to the crotch, being launched through roofs, crushed by several face-palms of doom, squashed by giant fly-swatters, dragged into the open air at Mach 17, and his most notable achievement, getting hit point-blank with a beam cannon that's able to annihilate planets. There is nothing that can kill this guy.
- A Lesson In Defeat: In the anime, at least; after an attempt for Skinship Grope on Astraea fails, 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
- Lovable Sex Maniac: He decorated his entire house with his childhood friend's panties and turned himself into a girl in order to get into the girl's baths and grope them... among many other perversions that are entirely Played for Laughs. Yet, he is always forgiven and still has girls falling for him left, right and center.
- Morality Chain: 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.
- Nice Job Breaking It, Hero: Nice job doing your comedic routine of buzzing off Angeloids within earshot of Chaos.
- Ordinary High-School Student: He is just a completely normal high-school student who loves his ordinary life, but one day he becomes the master of an Angeloid who fell from the sky and his normal life seems to come to an end.
- Panty Thief: He frequently steals women's underwear. Sometimes he even wears stolen panties as a mask!
- Please Don't Leave Me: In the final chapter, he repeatedly orders and begs Ikaros to turn back and stay with him before she dies due to getting too close to Synapse without permission.
- Raging Stiffie: His crotch goes into erection whenever he sees something attractive, such as Sohara or the Angeloids.
- Robosexual: He feels attracted to Angeloids which are basically angelic robots, mainly Ikaros and Nymph.
- Shared Family Quirks: His perverted character traits come from his mother.
- Sobriquet Sex Switch: When Tomoki gets turned into a girl, he goes by Tomoko.
- Spanner in the Works: The 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 emotional powerhouse for his Amazon Brigade.
- Strong Family Resemblance: Towards his MOTHER! She even looks exactly like Tomoko!
- Supporting Protagonist: Although Tomoki is the center of the harem, and it's hinted at that he's The Chosen One, the drama is largely surrounded the Angeloids, and the one who's actually trying to solve the mystery of Synapse is Sugata.
- Unstoppable Rage:
- Tomoki's response to the Harpies being blown up because they went against their master's orders is... just see it for yourself.◊
- And when Ikaros died, his reaction was even worse.
- Unwanted Harem: 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.

- The Unfavourite: BIG TIME. 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.

- Literal Genie: Ikaros can fulfill any wish her master asks for, but it's better to be careful of how to ask it. Tomoki wishes in jest that he was ruler of the world. Ikaros grants it by making every other person in the world vanish. She does explain that making him a traditional ruler would be impossible because no one would take a doofus like him seriously. Ikaros normally cannot undo her wishes, but fortunately Tomoki wishes that it was All Just a Dream.

- Her weapons are named after Greek gods. Artemis, Apollon (her bow, whose power is said to be enough to annihilate a country), Aegis, and Hephaestus. The anime traded out Hephaestus for the Uranus System, a giant battleship/Mobile Armor that seems to be generated from the sky itself.
- Rose-Haired Sweetie: She has rosy pink hair, and she's innocent, docile and devoted to her master.
- Short Hair with Tail: Most of her hair is in a bob haircut, while she has two long tails tied at the nape of her neck.
- The Stoic: She always has the same expressionless face that makes everyone wonder if she will ever smile.
- Subordinate Excuse: As his servant Angeloid, she always must stay by her master's side and do anything to please him. Of course, that's not the only reason she is so devoted to Tomoki.
- Sugar and Ice Personality: As emotionless and quiet as she might be, she clearly loves her master a lot and is very devoted to him.
- Super Drowning Skills: 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.

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.
- A-Cup Angst: Made worse by the fact that her Love Interest is a devout fan of breasts and she will be eternally flat according to her age device. 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.
- Big Eater: Ate four pieces of cake in chapter 60 — her's, Astraea's, Ikaros's, and Tomoki's.
- Brown Note: While it's debatable as to how truly destructive it is in canon, listening to her singing voice is rightfully described as Hell. Fridge Brilliance when you remember that her named attack is called Paradise Song. Though her attack actually does less damage than just her singing.
- Covert Pervert: 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.
- Crippling Overspecialization:
- As noted by the Master, there's not much use for an electronic warfare type against underdeveloped downers. 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.
- In a gag episode of the anime, she is able to hack directly into Tomoki's brain to block all memories of his ability to swim.

- Fantastic Racism: Has an extremely low opinion of "bugs", at least at first.
- Going Commando: In a side chapter, she reveals to Tomoki she doesn't wear any panties because she thinks they're "dirty". Tomoki wastes no time to take a peek under her skirt.
- Heel–Face Turn: While she was never overtly evil, she was working under the orders of her master, who treated her like absolute garbage. Then comes Tomoki and his friends, who treat her really well without any ulterior motives.
- Heroic Sacrifice: Uses her self destruct in an attempt to take out Minos. It fails, although it does destroy the Zeus core and allow Tomoki access to Synapse.
- Jerkass: At first, Nymph is an obnoxious and cruel Angeloid who harasses Tomoki and Ikaros. Even after her Heel–Face Turn and Character Development, her treatment of Astraea borders on this. This is why Oregano hates her.
- Little Big Sister: She's technically Astraea's big sister, but doesn't look like it.
- Make Me Wanna Shout: Her Paradise Song attack.
- The Millstone: 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.
- Rapunzel Hair: Has some really long pigtails. Activating her Pandora System just makes it even easier to notice.
- Reality Warper: Ikaros can affect reality with her cards, but Nymph can hack reality.
- Religious and Mythological Theme Naming:
- Named after the nature spirits of Greek mythology.
- Her Fundamental Particle Jamming System is named after the Greek goddess, Aphrodite.

- The Worf Effect:
- 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.
- You Gotta Have Blue Hair
- Zettai Ryouiki: Grade S!
The Harpy Twins
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.
- Comically Missing the Point: When the oldest is 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.
- Crippling Overspecialization: Their High-Altitude wings are exactly like they sound - designed for high altitude. At lower altitudes, their flight capabilities are relatively worthless.

- Apologetic Attacker: 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 to the point that it's considered a ranged weapon. Chrysaor III is big enough that it qualifies as a ranged weapon by default.
- Big Eater: 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).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!"
- Big "SHUT UP!": After Minos orders her to kill her friends one too many times, she screams at him to shut up as she breaks her chain.
- Boobs of Steel: She has the second largest breasts of any character in the series behind Sohara and is stronger than Ikaros in a purely physical sense, and her rack speaks for itself.
- Brainless Beauty: She's very beautiful, but not the smartest girl around.
- Butt Monkey: Arguably even lower than Tomoki.
- Crippling Overspecialization: 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.
- The Ditz: 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.
- Dumb Blonde: She is a beautiful blonde girl, but is also extremely dumb. Of course, it's not her fault — each Angeloid can only excel at two things and be bad at the third. She's good at fighting and emoting, so she lacks intelligence.
- Dumb Is Good: She's a complete airhead and one of the nicest characters in the series.
- Dumb Muscle: She's exceptionally stupid, but she's also exceptionally strong. 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.
- Dumbass Has a Point: She occasionally notices things the others miss.
- Extreme Omnivore: Rabbit pellets and fish bait are yummy to Astraea.
- Friendly Enemy: Before she broke her chain, she was extremely friendly with the main cast. So friendly, in fact, that her switching sides can't even really be called a Heel–Face Turn.
- Hair of Gold, Heart of Gold: Very nice and friendly even back when she was an enemy.
- Kick the Dog: An accidental case. She mocks Nymph for having no wings, trying to simply Poke the Poodle and not realizing beforehand how sensitive a subject it was. However she immediately regrets it afterwards upon seeing how hurt Nymph was.
- Kindhearted Simpleton: A complete airhead, but one with a good heart.
- Leitmotif: The aptly named Delta.
- Lightning Bruiser: 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.
- Luckily My Shield Will Protect Me: 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' Beehive Barrier that only faces one direction.
- Ms. Fanservice: She has quite an oversized bust and her skimpy outfit often give Panty Shot. In addition, her low processing levels often result in her easily falling victim to many of Tomoki's perverted schemes regarding her massive breasts.
- Named Weapons: The Photonic Oscillation Blade Chrysaor and the Aegis-L Shield (a version of Ikaros' Aegis that can only guard the front).
- Nice Girl: She's so nice that she can't help but give Tomoki a hand even when she was actually trying to kill him.
- Poke the Poodle: Some of her attempts to kill Tomoki fall under this, such as trying to poison him with a laxative.
- Rapunzel Hair: Astraea has blonde long hair that reaches down to her ankles.
- Religious and Mythological Theme Naming: Named after the Greek goddess of innocence and purity Astraea, who abandoned Earth due to the wickedness of humanity and became the constellation Virgo.
- Sacrificed Basic Skill for Awesome Training: 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.
- Smarter Than You Look: 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.
- Too Incompetent to Operate a Blanket:
- 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 lacks emotions but is an extremely intelligent, if naive, powerhouse. Nymph has next to no combat ability but compensates with her ability to hack reality, and is easily susceptible to emotional mood swings. Astraea is a complete dumbass, but she's also a monster in close combat who can hit hard, hit fast, and shrug off almost anything and is supposedly capable of overpowering even Ikaros when fighting up close, and she has a wider and more stable emotional range than the other two combined.
- Chapter 75 is the worst instance of this, with her voluntarily sacrificing herself just so Chaos wouldn't die alone.
- Training Montage: She had one during the credits of the fourth episode in Forte.
- Unskilled, but Strong: 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.
- Vapor Wear: Her top makes it obvious she doesn't wear a bra.
- Winged Humanoid: She bears Acceleration model wings, which allow her the speed/agility combo that she needs for close-quarters combat.
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.
- Bad Habits: Dresses up like a nun.
- Big Brother Worship: Towards Tomoki.
- Break the Cutie: If you don't feel bad for her at the end of chapter 47, you have no soul.
- Cannibalism Super Power: She claims to "eat" other Angeloids to gain their powers, though she's really just taking their cores.
- Cute and Psycho: Chaos is what happens when you mix Ax-Crazy with Love Freak. What you get is the creepiest Moe character in the series who wants to share her "love" with everyone.
- Does Not Like Shoes: She goes barefoot in every scene she appears in.
- Easily Forgiven: In the Reset Button Ending.
- Glasgow Grin: Her face is constantly adorned with one of these in the anime. It's creepy. Moreso on Tomoki's face.
- Knight of Cerebus: Every chapter with her in it is noticeably darker.
- Love Freak: 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".
- Love Hurts: She believes that pain is love and as a severe Love Freak she seeks to spread her "love" to everyone.
- No Sense of Humor: 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.
- Omnicidal Maniac: 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.
- Plot Driving Secret: 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. As of Chapter 70, this is no longer true.
- Phlebotinum Overload: Her multiple cores ultimately explode and killer her and Astraea.
- Poor Communication Kills: Hiyori and Tomoki.
- Religious and Mythological Theme Naming:
- According to Greek mythology, Chaos is the origin of everything, and the first thing that ever existed. It was the primordial void, the source out of which everything was created, including the universe and the gods.
- 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", as well as stronger versions of Ikaros, Nymph and Astrea's weapons after assimilating the Melan models.
- Surprise Party: Has one in the special bonus chapter, though the guests were actually forced to go by Mikako.
- Token Mini-Moe: She gets a more mature body later on due to the Pandora System.
- Tragic Mistake: Killing Tomoki.
- Troubling Unchildlike Behaviour: 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.
- What Is This Thing You Call Love?: She doesn't know what love is, but that doesn't stop her from being a freak about it. Eventually, she comes to the conclusion that pain is love. She begins to truly understand it after her Heel–Face Turn.
- Winged Humanoid: 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.
- You Gotta Have Blue Hair: Green actually.
- You Will Be Assimilated: The biggest part of her power set is the ability to mimic the abilities of anything her wings pierce. 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.
A second-generation Angeloid which was sent to ambush Tomoki. Her formal designation is Type Eta, Underwater Combat Angeloid.
- Impaled with Extreme Prejudice: Hid in the water to ambush the Angeloids, ends up getting killed from behind by Chaos.
- Our Mermaids Are Different: She's a robot mermaid marine-combat type Angeloid, thus averting the Winged Humanoid archetype of Angeloids and Synapse denizens.
- Winged Humanoid: Comes with being an Angeloid, however, her wings have more of a fin-like design to them to go with the mermaid design.
A generic medical specialist Angeloid. One follows Sugata back from a dive game, after which she associates herself with Mikako. This... has consequences...
- Emotionless Girl: Oregano has no emotional control.
- 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.
- Winged Humanoid: Comes with being an Angeloid.
Tactical Weapon Angeloid, type Theta, Melan. Equipped with a Variable Wing Core (Ikaros' wings), and mass-produced in black-winged, black-haired mimicries of Ikaros, Nymph, and Astraea.

- 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 .
- 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.
- Super Speed: Has speeds that rival that of Ikaros.
- Winged Humanoid: They bear Variable wing cores - and unlike Chaos, these are perfect Variables. However, 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 black-feathered.
A few floating islands in the sky, which happens to stop over Sorami town at the time being. Their denizens are flesh-and-blood angels, and they possessed vastly advanced technology compared to humanity.
