Manga Wiki

Sora no Otoshimono (そらのおとしもの?), also known as Heaven's Lost Property, is a Japanese manga series written and illustrated by Suu Minazuki. The plot revolves around Tomoki Sakurai, a highly perverted young man struggling to live a peaceful life. His already-difficult life worsens when he encounters a fallen Angeloid named Ikaros, who soon becomes his servant.

Sora no Otoshimono began monthly serialization in the May 2007 issue of manga magazine Shōnen Ace. The first tankōbon was released by Kadokawa Shoten on September 26, 2007, with a total of thirteen volumes released as of November 26, 2011. An anime adaptation produced by AIC aired in Japan between October and December 2009,[1] and a second season aired between October and December 2010. An anime film was released on June 25, 2011. The anime is licensed in North America by Funimation Entertainment, who will be releasing the series in 2011 and the film in 2012.


Tomoki Sakurai is a young man whose motto is "Peace and quiet is the best", but he finds it difficult when he has to put up with his next door neighbor with a killer karate chop, Sohara Mitsuki; Eishiro Sugata, an eccentric scientist bent on discovering the "New World"; and Mikako Satsukitane, a borderline sadist. One day, while he was witnessing a strange anomaly in the sky, a UMA (Unidentified Mysterious Animal) falls from it. What falls from the sky is an Angeloid named Ikaros, who soon becomes Tomoki's servant. From then on, more Angeloids come to him, and with this, he finds himself struggling for his peace and quiet, but at the same time finds pleasant things the Angeloids bring him.


Main characters

Tomoki Sakurai (桜井 智樹 Sakurai Tomoki?)
Voiced by: Soichiro Hoshi (Tomoki), Saki Fujita (Tomoko) (Japanese), Greg Ayres (Tomoki), Alison Viktorin (Tomoko) (English)
Tomoki is this series' main protagonist, who wants nothing more than a peaceful and quiet life in town. However, his life is forever changed when he meets Ikaros and the other Angeloids. While being shown to be a shameless pervert (to the point of creating peepholes via improvised pipe periscopes to every peeping spot all over town[2]), he is usually a kind and sincere person. Tomoki was heavily influenced by his equally perverted grandfather, and would often appear to give him (albeit perverted) advice, which always seems to help Tomoki in dire situations.
Tomoki frequently experiences a dream involving him meeting an angel, who takes off into the sky to his disappointment. This was later revealed to be a gateway between the human world and the world of Synapse.[3] Tomoki has shown feelings for Ikaros and Nymph and takes on the task of helping Ikaros become more human. He has also tried to break the Angeloids' tendency to obey their masters' orders completely by letting them do whatever they want, giving them a great degree of freedom to make their own individual decisions. While he constantly laments that his idealistic world of peace and quiet is ruined by the appearances of the Angeloids, he admits that he does see them as family and enjoys their company. A running gag in the series is that most of the main characters usually gather in his house for seemingly no reason other than for fun. Another running gag in the series is that whenever Tomoki gets frustrated, he comically overturns his coffee table in anger, sometimes doing so in situations where there are no coffee tables, during which he materialises a "coffee table of the heart".
On rare occasions, he transforms to a female alter-ego called Tomoko (智子?) through a quantum converter made by Synapse, and mainly uses this new form to blend in with the other girls so he can peep on them unnoticed. However, if Tomoki becomes sexually stimulated for too long while as Tomoko (or any other object), the transformation will end and the converter will short out. A small note is while all of the other characters are drawn in their original parameters, Tomoki is mostly drawn in super deformed parameters, with the only times being drawn in his original parameters is when he is serious or feels relaxed.
Sohara Mitsuki (見月 そはら Mitsuki Sohara?)
Voiced by: Mina (Japanese), Trina Nishimura (English)
Sohara is Tomoki's childhood friend who lives across the road from him and often goes to his house in the morning to wake him up. As a child, she was constantly ill and thus had few friends.[4] She is continually jealous of Tomoki's relationships with the various Angeloids and generally acts on this jealousy by karate-chopping Tomoki; however, she also does it whenever he's being perverted in her presence. She is actually secretly in love with Tomoki. As the series progresses, her breasts get bigger and bigger to the point that no bras will fit her and thus finds herself forced to not wear one, which only encourages Tomoki's perversions. Apparently, her dreams sometimes involve her and Tomoki being together in many different provocative situations involving things from cosplay to bondage, which suggests she actually likes it when Tomoki is perverted.[5] However, she is shown to get angry when he directs his perverted actions to other girls. Her karate chops are capable of ridiculous cutting power, enabling her to chop through pretty much anything.
Ikaros (イカロス Ikarosu?)
Voiced by: Saori Hayami (Japanese), Brittney Karbowski (English)
Ikaros is a "Pet-Class Angeloid, Type Alpha" who becomes bonded to Tomoki at the beginning of the story, which is symbolized by the invisible chain leading from her collar to Tomoki's hand. She displays a very submissive, melancholic personality and is completely subservient to Tomoki's wishes. Ikaros possesses the ability to grant seemingly any wish through the use of several techno-magical cards. Despite her passive appearance, Ikaros has displayed moments of aggressiveness whenever Tomoki's life appears to be in danger. She weighs 48 kilograms (106 pounds), stands at 162 cm (5 feet 3 inches) and her wing type is listed as "Variable". Her "Variable" wings are extremely valuable and are highly desired by Synapse.[6] Since she began living with Tomoki, she has become somewhat of a live-in maid where she is the one that cooks breakfast, lunch, dinner, and wakes up Tomoki in the morning, and otherwise takes care of the house. While she begins the series with a poor grasp of human emotion, she eventually begins to acquire emotions and begins to fall in love with Tomoki. The reason for this is because she has high battle and processing capability, but has low emotional control as a result. She has been shown to be willing to sacrifice herself if it means ensuring the safety of Tomoki. Ikaros is also shown to do anything that will gain Tomoki's approval, even if it's a questionable act (normally involving Tomoki's perverted schemes) on Tomoki's part; she admits that as long as Tomoki is happy, she will also be happy as well. In one chapter, she became extremely depressed when Tomoki broke the imprinting between them and finds it difficult to express her feelings (Mikako notes that Ikaros has difficulty being open with her emotions involving Tomoki unless his life is in danger) until she was ordered to throw Tomoki into the ocean. This puts enough emotional stress on her that she tearfully begs Tomoki not to throw her away.[7] Though she is the slowest to anger, she becomes extremely frightening when angered (partly because her expression remains neutral even when angry), and is very unmerciful in delivering punishment (generally by repeatedly shooting the offender with Artemis). She loves when Tomoki pats her on the head, and even becomes depressed when he is unable to do it. She is noticeably the only girl in the series that Tomoki does not sexually harass in any way; when queried about this even he is unsure of the reason.
As the story progresses, it is revealed that Ikaros is not a "Pet-Class" Angeloid, but is actually a "Strategic Battle-Class" Angeloid and is the most powerful of the First Generation Angeloids.[8] She takes little physical damage when she is shot, can fly to speeds up to Mach 24, and is able to withstand water pressure better than most submarines. In the past, she was called the Uranus Queen (空の女王(ウラヌス・クイーン) Uranusu Kuīn?) and terrorized Synapse due to her immense power and battle capabilities. She was originally sent to Earth as a weapon of judgment and is responsible for destroying the Tower of Babel.[8]
Ikaros is seen to be with the only Angeloid who has a "Battle Mode". When she activates her battle mode ("Uranus Queen Mode"), her wings are engulfed in bright light, her eyes become red, and a halo appears over her head. Ikaros can generate a nigh-invincible energy shield called Aegis (イージス Ījisu?). She also possesses several powerful weapon systems: Artemis (アルテミス Arutemisu?), a series of multi-directional homing energy projectiles fired from her wings, and Apollon (アポロン Aporon?, Stylized as APOLLON), a bow that can fire energy-charged arrows capable of obliterating a country in a single shot. She also possesses the ability to summon and control a third weapon called Hephaestos (ヘーパイストス Hēpaisutosu?), which is part of an anime-only weapon system called the Uranus System (ウラヌスシステム Uranusu Shisutemu?), which vaguely resembles a massive cloaked spaceship. Both were first used in battle against the twin Gamma Harpies, but only the Hephaestus cannons were shown and dwarf the Harpies' Prometheus in firepower and size. It was later seen again in the second season in full scale against the second-generation Angeloid Chaos, but it was later destroyed after Ikaros took Chaos to the bottom of the ocean with it.
In chapters 55 and 56 of the manga, Ikaros suffered heavy damage as clones of Nymph and Astrea, as well as herself, were sent from Synapse in order to eliminate Tomoki. The situation seemed hopeless, even when Nymph and Astrea were able to take a few down using their hacking and combat skills respetfully, Tomoki, despite his injuries, managed to crawl to her and caressed her head. As an army of Angeloids loomed over them, Tomoki's act activated Ikaros' Pandora program, causing her to evolve into a form called Ikaros version II. In this form (albeit from gaining upgraded weaponry and a new outfit), Ikaros gains a second set of wings (called "Dual Variable Wings") and her combat strength is nearly doubled, being able to annihilate the entire legion of clones with her Artemis.[9]
A running gag in the series involves Ikaros occasionally seen holding a watermelon, a fruit she curiously takes an interest in; this leads her to eventually grow a patch of watermelons in the garden. Additionally, after a chicken-raising contest in one of the omake chapters, she also develops a hobby of raising chickens and becomes angry if the other Angeloids hurt her chicken even by mistake, attacking the offenders with her weapons and causing mayhem all over Tomoki's house (which often results in Tomoki kicking all of the Angeloids out of his house until he calms down). Ikaros's name is a play on the Greek mythological character Icarus, whose fate (falling from the sky) can be related to Ikaros's introduction into the storyline.
Eishiro Sugata (守形 英四郎 Sugata Eishirō?)
Voiced by: Tatsuhisa Suzuki (Japanese), Eric Vale (English)
Sugata is the leader of the New World Discovery Club (新大陸発見部 Shin Tairiku Hakkenbu?). He is a scientist of sorts and is currently researching the Angeloids and Synapse with Nymph's help to regularly dive into Synapse (during which he regularly outwits and escape the Harpies). He lives in a tent near a river and is always seen wearing his school uniform, as he has no other clothes, and continually praises various European explorers such as Magellan and Columbus. At some point he forcefully drafts Tomoki into the New World Discovery Club of which Sohara, Mikako and Ikaros later also join. Due to the little flexibility of his diet, usually limited to what he can find in the wild such as fish while also fighting bears over territory, he has a habit of taking Tomoki's food whenever he visits his house. He is highly eccentric and has some past involvement with Mikako's family (her servants even call him master), and is also shown to be very intelligent but also stoic in all his appearances, generally behaving very in a very deadpan fashion unless it involves a "New World" (a fact that Tomoki has exploited on more then one occasion to get Eishiro to help him peep at girls). He is also equal on combat abilities with Mikako. In chapter 51, he accidentally brought a Angeloid from Synapse with him (revealed to be the medical Angeloid Oregano), whom he later dumps on Tomoki.
Mikako Satsukitane (五月田根 美香子 Satsukitane Mikako?)
Voiced by: Ayahi Takagaki (Japanese), Jamie Marchi (English)
Mikako is an upperclassman to Tomoki and Mitsuki and the President of the Student Council. She is Sugata's childhood friend, whom she refers to as "Ei-kun", and the heiress of a Yakuza family. She is manipulative, cunning, highly intelligent and somewhat sadistic, usually towards Tomoki. She is forced to take supplementary lessons due to "failing in morals".[10] She also is equal to Sugata in terms of combat abilities. However, Nymph states that she has a grip power of 400 kg (roughly 882 pounds), which serves to indicate she has a great degree of strength, especially for a normal human.Template:Episode needed She is the chief mastermind of many schemes in the manga, and Sugata normally enlists the help of Tomoki (and occasionally some others) by persuading him to totally shut down her plans. Many of her schemes are directed to Tomoki, serving to put him in undesirable situations and humiliating him, which suggests she sees him as a toy for her personal entertainment. Nevertheless, in situations of genuine emotional distress, she can be surprisingly thoughtful (if in her own unique way); when Tomoki breaks the contract between him and Ikaros in one chapter, Mikako immediately repairs their relationship and contract by ordering Ikaros to throw Tomoki into the ocean.[7] She is shown to have romantic feelings towards Sugata, as shown in the anime when she asks Tomoki to choose a bride and stated she is already taken (she shows this by wrapping her arm around Sugata's and changing into a wedding dress).[11] Another instance is shown when she gets angry when Tomoyo (Tomoki's mother) flirts with her childhood friend (it is Tomoki who suffers her wrath, in place of his mother).[12]
Nymph (ニンフ Ninfu?)
Voiced by: Iori Nomizu (Japanese), Kara Edwards (English)
Nymph is an "Electronic Warfare Angeloid, Type Beta" (電子戦用エンジェロイドタイプβ(ベータ)?) who mysteriously appears in Tomoki's house. She is condescending towards humans, whom she refers to as "bugs"; this is no doubt a result of her former master's constant belittling of humans, or as he calls them, "Downers". After she spends time with them, she realizes the error of her ways and starts to treat them as equals. She weighs 29 kilograms (64 pounds), stands at 139 centimeters (4 feet 6 inches), and her wing type is listed as "Not Variable" and "Stealth".[13] Because of this, Nymph can completely conceal her wings unlike Ikaros, who can only retract her wings to a certain point. She is originally sent to return Ikaros to Synapse. However, because she is less powerful than Ikaros, she is unable to do so. Her master later implanted a bomb within her collar that will explode after the green bars on it disappear, which was later disabled from the teamwork of Tomoki and friends. She soon develops feelings for Tomoki (albeit in a tsundere fashion), and later confesses to him. After the Gamma Angeloids attempt to kill her, she betrays Synapse and assists Tomoki, and moves into his home. Her wings were torn off by the Gamma Angeloids, but were regrown when she accepts Tomoki as her new master. However, in her delight at having her wings regrown, she forgot about the Imprinting process and finds it extremely difficult to broach the subject to Tomoki; by her own admission, it is not a difficult task, but she feels embarrassed enough to eventually back out of asking. Eventually, Nymph asks Tomoki to Imprint with her, but he refuses, saying that he wanted her to live freely. She is named and modeled after the nature spirits of Greek myth.
As an Electronic Warfare-type Angeloid, she has the ability to hack computer systems better than any other Angeloid. She is also capable of hacking other Angeloids as well as humans. She can also fire a high-powered energy beam from her mouth called "Paradise Song" (パラダイスソング Paradaisu Songu?). When being hacked by Hiyori, Nymph is given an order by Tomoki, to not lose no matter what, at which point Nymph displayed a new ability, a "fundamental particle-jamming system" called Aphrodite (アフロディーテ Afurodīte?). When using this, she becomes immune to hacking and her wings grow into a butterfly shape. However, using it generates a lot of heat, causing her to enter cooling mode as a result.[14] Nymph has high processing capabilities and has high emotional control, but as a result she is low in raw power. She also has the most powerful radar of the three first-generation Angeloids (Ikaros has stated that her own radar's proficiency cannot be compared with that of Nymph even though she was wingless at that time, though it was stated by Nymph herself that her radar was a lot weaker at the time her wings had not grown back[15]). Nymph is shown to have a sweet tooth; her appearances mostly show her snacking on chips and other snacks, and is shown to have a penchant for watching soap operas. She refers to the other Angeloids by their types rather than their names (i.e. Ikaros→Alpha).
Astraea (アストレア Asutorea?)
Voiced by: Kaori Fukuhara (Japanese), Carli Mosier (English)
Astraea is a "Close-Combat Angeloid, Type Delta" (地戦闘用エンジェロイドタイプΔ(デルタ)?) sent by Synapse to kill Tomoki after he violates one of their rules. She is somewhat an airhead and has limited intelligence due to having low processing power, making her somewhat the dumb blonde of the group. She weighs 48 kilograms (106 pounds), stands at 159 cm (5 feet 2 inches), and her wing type is stated to be "Not Variable" and "Super Acceleration".[16] She is the last of the First-Generation Angeloids to break free from Synapse's control by Tomoki's influence; when she is ordered by the Master of Synapse to eliminate Nymph, she breaks off her chain and engages in combat with Chaos.[17] She mostly serves as the series' comic relief, alongside Tomoki. The duo often squabble, but will comically end up agreeing with each other on some absurd conclusion. She refers to Ikaros and Nymph using the senpai honorific since she is the "youngest" of the first-generation Angeloids, and is named after the Greek mythological figure Astraea.
Astraea also harbors feelings for Tomoki despite often being a target to his perversions. However, despite her lack of intelligence, she does display a good level of common sense in situations where Ikaros would be clueless about. Ironically, she is also regularly found starving due to the fact that she does not know how to hunt or obtain food by her own means, which was shown when she ate a fish bait because she was hungry.[18] She eventually realizes that she has fallen in love with Tomoki, after wondering about why she had seen Chaos crying and what she had said about love.[19]
Astraea has been described as being the fastest of the Angeloids and having greater close-combat capabilities than Ikaros. However, she is only equipped with close-combat weapons and is therefore extremely vulnerable to long-range attacks. She wields a super-osciliating photon blade called Chrysaor (クリサオル Kurisaoru?), which can even penetrate Ikaros' Aegis defense system. For defensive purposes, she uses the upgraded version of Ikaros's Aegis shield called Aegis L (イージス L Ījisu Eru?, "L" standing for "left", as it appears on her left arm). Although it is more powerful than the Aegis shield, Aegis L can only deflect frontal attacks, unlike Aegis which creates a shield that covers all angles. Also, Aegis L cannot be deployed for long periods of time due to its massive energy requirements.[20]
Hiyori Kazane (風音 日和 Kazane Hiyori?)
Voiced by: Yōko Hikasa
Hiyori is a second-year student at Tomoki's school. She has feelings for Tomoki and joins the New World Discovery Club in order to get closer to him. In reality, Hiyori is an Angel who was first seen inside some sort of sleeping chamber when Sugata went to Synapse. The chamber connects her to her body on Earth, which functions like an avatar. Sugata was hesitant on letting her join his club since there are still a lot of things he does not know about what she really is. However, he welcomes her anyway, since her membership will allow his club to receive more funding. Thus far, nobody, except Sugata, Nymph, and Ikaros, is aware of Hiyori's true identity.
Hiyori got rather embarrassed when it was suggested that she was dating Tomoki, suggesting that while she likes Tomoki, she has not even considered as far as dating him yet, and her presence becomes a source of major discomfort for Sohara, Nymph, and Astraea.[21] This stems from the realization that Hiyori is always kind and caring to Tomoki, while the others seem to only see his "faults". Eventually, Hiyori manages to confess her feelings to Tomoki, which leaves him in shock as no girl has ever confessed to him before. However, her time with Tomoki was ultimately cut short when a careless truck driver ran her over, causing her body to disappear and her existence erased from everyone's memories (except the Angeloids and Tomoki).
Later on, Hiyori returns as a "Type Zeta" Angeloid armed with a khakkhara called Demeter (デメテル Demeteru?), which has the power to manipulate the weather, and has more sophisticated hacking abilities than Nymph. Her master was Nymph's previous master, who turned her into an Angeloid so she could live her "dream" on Earth. Luckily, Hiyori was released from her master's control thanks to Nymph's hacking abilities, allowing her to stay on Earth as a free Angeloid. Hiyori later drops out of the New World Discovery Club, since she already accomplished her goal of getting close to Tomoki, on the grounds that she already knows who he likes, but she then kisses him, stating that her friends said she was rather aggressive (which hints that she wasn't going to give up on Tomoki just yet), though she still remains on friendly terms with Tomoki and the others. In later chapters, she also begins appearing more as a regular character.[22]

Supporting characters

Daedalus (ダイダロス Daidarosu?)
Voiced by: Asuka Ōgame (Japanese), Monica Rial (English)
Daedalus is an angel and the creator of Ikaros, Nymph and Astraea, the first generation of Angeloids. She frequently appears in Tomoki's dreams, but she flies away leaving Tomoki crying. She comes to his dreams asking him to help save her. Her name originates from the Greek mythological character Daedalus, the father of Icarus, and her face is obscured in all of her appearances. It is hinted that she may have feelings for Tomoki. She frequently works with Sugata from time to time when he visits Synapse.
Oregano (オレガノ?)
A Medical Specialist Angeloid from Synapse who mysteriously managed to come to Earth by tagging along with Eishiro as he teleported back from one of his trips. Mikako took her in afterwards, as Tomoki didn't have enough money left to support another Angeloid. While Tomoki and Nymph were initially concerned that Mikako would subject Oregano to her sadistic methods of self-amusement, it turned out that Oregano herself is as vile and sadistic in nature as her master who, while putting on a facade of innocence and cluelessness (much like the personality of Ikaros, which prompts Tomoki to coin the nickname "Miniros") in front of Tomoki and most others, subjects Nymph to various kinds of torture just as her master does when she's alone, even going as far as to drop a number of grenades after trapping her in a cell (which subsequently do explode on her) while making it look like Nymph was the one bullying her. Thus at present she is not on good terms with Nymph while appearing as a quiet and innocent Angeloid to all others. She appears to favor Tomoki, and seems to respect Ikaros.


Master of Synapse (空(シナプス)のマスター Shinapusu no Masutā?)
Voiced by: Shinichiro Miki (Japanese), Mike McFarland (English)
The sadistic and ruthless leader of Synapse. The main antagonist of the series, he finds enjoyment in torturing the Angeloids he owns (both physically and emotionally), seeing them as merely his playthings to which he can do with as he pleases and discarding them while considering them nothing more than trash. He is condescending towards humans, referring to them as "Downers", a trait that would be later shared with Nymph. Though because of his arrogant ways and believing that the Angeloids that serve him will obey his every order, he always reacts surprised when he witnesses one of them break their chain or go against his orders. He is often seen on his throne with two Angeloids beside him and, like Daedalus, his face is obscured in all of his appearances. In chapter 47 of the manga, it is revealed that he has created an "Ultimate Air Defense System" called Zeus (ゼウス Zeusu?).
Harpies (ハーピー Hāpī?)
Voiced by: Michiko Neya (Harpy 1), Maya Okamoto (Harpy 2) (Japanese), Clarine Harp (Harpy 1), Stephanie Young (Harpy 2) (English)
The Harpies are a pair of Angeloids introduced as "Ambush Angeloids, Type Gamma" (要撃用エンジェロイドタイプγ?), and answer directly to the Master of Synapse. They are responsible for tearing off Nymph's wings and are also guards at the main entrance of Synapse. Their main weapon is a large cannon on their left arms called Prometheus (プロメテウス Purometeusu?), which fires white-hot projectiles of 3000 degrees Celsius at 4 km/s. They are named and modeled after the harpies of Greek mythology.
Chaos (カオス Kaosu?)
Voiced by: Aki Toyosaki
Chaos is a "Second-Generation Angeloid, Type Epsilon" (第二世代エンジェロイドタイプε Dainisedai Enjeroido, Taipu Epushiron?) and the first major antagonist of the series. She is ironically the most miniature and child-like Angeloid, weighing 19 kilograms (her initial appearance, while she weighs 20kg in her Version 2 specs) and being only 107 cm (3 feet 6 inches) in height.[volume & issue needed] Her wing type is listed as "Imperfect Variable" and "Amphibian", and she is equipped with an "Anti-Perception System" called Medusa and a "Super-High-Speed Atomic Vibration Generator" called Chimera.[volume & issue needed] Her nun-like garments has the ability to manipulate her appearance through elaborated illusions, mimicking someone dear to her victim in order to instill turmoil and confusion (as her name implies), as she did against Nymph by taking on the likeness of Tomoki.[volume & issue needed] She lacks wings like other Angeloids, instead sporting a wicked array of bladed, almost organic-like appendages which act as an offensive weapon. Unlike most Angeloids who lack the ability to dream, Chaos has the ability to enter another person's dream, once doing so against Tomoki in her initial appearance. What is most eerie about her is her strange obsession with love, having asked to Tomoki, Nymph, Astraea and Ikaros, often in an extremely creepy manner, what love is, to which Ikaros responded that love, for her, was a sensation of pain in her reactor, obviously in a figurative sense.[23]
Chaos first appeared to torture Nymph and then fought Ikaros, whom she initially bested through her illusions, and Astraea. She battled Ikaros again, though this time the latter saw through her illusions and defeated her, sending Chaos into a deep abyssal chasm where she was temporarily incapacitated due to the great water pressure. While there, she wondered about Ikaros' statement to what love means, coming to a dreadful conclusion: love equates to pain. Chaos was left in the abyss, dismembering and devouring fish to—in her own words, grow bigger—and show her "love" to everyone. In chapter 45 of the manga, it is shown that she devoured and absorbed Seiren, one of the Sky Master's Angeloids, with it revealing that she has a "Self-Evolution Program" named Pandora (パンドラ?).
In the final episodes of Sora no Otoshimono: Forte, she returns as an adult, having consumed many fish and birds during her time stuck in the ocean. She fought Nymph and Astraea, easily overpowering them until Ikaros' arrival despite her feverish state. She was later defeated by Astraea and Ikaros using their upgraded weapons (courtesy of Nymph) and briefly shuts down afterwards, in which a padlock-like device was attached to her chain by Tomoki (courtesy of Daedalus). She was then reverted back to her childlike form by Daedalus and returns as a good Angeloid, later becoming Tomoki's Angeloid.
Seiren (セイレーン Seirēn?)
Seiren is an "Underwater Combat Angeloid, Type Eta" (水中戦闘用エンジェロイドタイプη(イータ)?) built by the Master of Synapse who appeared in chapter 45 of the manga. Her appearance in the manga was brief, as she was impaled in the back by one of Chaos' wings before being devoured and absorbed by her just after she was ordered by the Master of Synapse to kill Tomoki and Ikaros. Her appearance is based on the sirens of Greek mythlology.
Ikaros Melan (イカロス=メラン Ikarosu Meran?, Ίκαρος Μέλαν)
Ikaros Melan, or "Black Ikaros", is a "Tactical Angeloid, Type Theta" (戦略エンジェロイドタイプθ(シータ)?) and the Master of Synapse's latest Angeloid. First appearing at the end of chapter 54, she is a dark copy of Ikaros, possessing a copy of the latter's Variable Wing core. However, being a Second-Generation Angeloid, her power far exceeds that of her original counterpart, as her Aegis shield cannot be penetrated even by Astraea's Chrysaor (and breaks the weapon when the latter tries to), yet a punch from Ikaros Melan can break through the Aegis L shield which is supposedly stronger than the original Ikaros' Aegis. She is eventually destroyed when the real Ikaros takes a shot from Ikaros Melan's Apollon, then activates her own Aegis around herself and Ikaros Melan so that its explosion (otherwise capable of annihilating an entire country) only blasts the two of them, resulting in a double suicide attack that leaves her own systems damaged to 97% and her self-repair program broken.

Other characters

Tomozo Sakurai (桜井 智蔵 Sakurai Tomozō?)
Voiced by: Hiroshi Iwasaki (Japanese), Bill Flynn (English)
Tomoki's equally perverted grandfather, whose dream was to make out with every woman in the world, but could not do so before his death. He frequently appears during Tomoki's flashbacks (or any other supernatural phenomena) to give him (albeit perverted) advice, which always seems to help Tomoki in dire situations.
Takehara (竹原?)
Voiced by: Takeshi Maruyama
Tomoki's math teacher.
Tomoyo Sakurai (桜井 智代 Sakurai Tomoyo?)
Tomoki's mother and Tomozo's daughter. She and her husband left Tomoki on a "world tour" when he was only 10 years old prior to the series' start. She reunites with her son in chapter 49 of the manga, where it is revealed that she has the same level of pervertedness as her son. Tomoyo is revealed to be bisexual, as she has shown an interest in the Angeliods' large breasts (sans Nymph) and a romantic interest in Sugata. She was finally stopped by her husband Tsutsumi at the end. Tomoyo bears a striking resemblance to Tomoko, Tomoki's female alter ego, and also has behavioral patterns similar to her as well, hinting it as the reason why Tomoki acts as he does as Tomoko. Nevertheless, like Tomoki, she also appears to have a gentle and compassionate side to her as well, as shown in her first appearances during Tomoki's flashback where she is shown cooking for him. Later in chapter 49, Tomoki grudgingly admits he was worried about her and was relieved that she was okay. She is shown comforting him like a mother.
Tsutsumi Sakurai (桜井 つつみ Sakurai Tsutsumi?)
Tomoki's father and Tomoyo's husband who appears at the end of chapter 49 of the manga. Like Sohara, he also packs a powerful karate chop which he uses on his wife for her pervertedness. Tsutsumi was actually married into the Sakurai family, while Tomoyo is the descendant of the Sakurai bloodline.

Tsukino Voiced by: Minako Kotobuki (Japanese), Cherami Leigh (English)


Synapse (シナプス Shinapusu?)
Synapse is an alternate world located in the skies that is home to the Angels and the Angeloids. It was first introduced in the series as a black hole above Sorami when Sugata did his research on the New World and as a result, believes that Synapse is the "New World" and begins to investigate it, with Nymph aiding him later on. In Synapse, there is a large dome that contains numerous Angels in sleeping pods, which connects them to their real-world avatars. If the avatar in the real world is killed, the people associated with them will have their memories erased, such as the case with Hiyori. Also in Synapse is a large obelisk called the Core, which has its rules written on it.
Angeloids (エンジェロイド Enjeroido?)
The Angeloids are a series of androids built by Synapse. As part of their name implies, they are modeled after the Angels and are programmed to serve their masters. They select their master through a process called "Imprinting", in which the chain attached to their neck collar extends to their chosen master's hand and ties it, connecting it to the collar. The first generation of Angeloids (Ikaros, Nymph, and Astraea) were built by Daedalus, while the second generation of Angeloids (Chaos, Hiyori, Seiren, and Ikaros Melan) were built (or in Hiyori's case, converted to) by the Sky Master. Although they are androids, they are at least partially biological in nature given that they can do things such as eat, cry and, (in a recurring case for Astarea) feel hunger.
Each Angeloid is designated with a letter of the Greek alphabet, which descends for every new Angeloid built. Ikaros, the first Angeloid built, is a "Type Alpha" Angeloid, while Ikaros Melan, the most recent Angeloid, is a "Type Theta" Angeloid. Each Angeloid has their own unique abilities and powers, which are determined by three factors: emotional control, battle capability, and processing capability. Unlike humans and Angels, Angeloids lack the ability to sleep or have dreams, with Chaos (and presumably Hiyori) being the only exception. Also, most Angeloids (except those like Seiren, or Chaos after devouring Seiren to evolve) cannot swim due to their wings being porous to water. The Angeloids' names, weapons, and abilities are derived from Greek gods, mythological figures, or (in Chaos' case) words that stem from Greek roots.
Self-Evolution Program Pandora (自己進化プログラムパンドラ Jiko Shinka Puroguramu Pandora?)
A program built into certain Angeloids that allow them to learn and adapt to various environments and situations and eventually evolve into stronger beings with additional capabilities. Chaos was the first to demonstrate its ability when she absorbed Second-Generation Angeloid Seiren and grew amphibian wings to be able to swim underwater. Later, Daedalus revealed that she built the Pandora program into all 3 of her First-Generation Angeloids but left it protected with another program so that the Angeloids don't evolve "by mistake" at will. During chapter 55, Nymph is the first one to break it and evolve to a stronger form, and at the end of the chapter, a severely damaged Ikaros, previously taken as irrepairable with 97% of her systems damaged and her self-repair program destroyed (and therefore considered as good as "dead" if not "permanently comatose"), also activates the Pandora program built inside her to evolve and restart as "Ikaros version II".
