Angeloids Vs Soul Society

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, stands at 162cm and her wing type is listed as "Variable". Her "Variable" wings are extremely valuable and are highly desired by Synapse. 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.
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 all Angeloids. 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" (ウラヌス・クイーン Uranasu Kuīn?) and terrorized Synapse due to her immense power and battle capabilities. She was originally sent to Earth as a weapon of judgement and is responsible for destroying the Tower of Babel.
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 two powerful weapon systems: "Artemis" (アルテミス Arutimisu?), a series of multi-directional homing energy projectiles fired from her wings, and "Apollon" (アポロン Aporon?), 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 "Hephaestus" (ヘーパイストス Hēpaisutosu?), which vaguely resembles a massive cloaked spaceship. It was first used in battle against the twin Gamma Harpies, but only its cannons were shown and dwarf the Harpies' Prometheus in firepower and size. A running gag in the series involves Ikaros occasionally seen holding a watermelon, a fruit she curiously takes an interest in. In the manga, this leads her to eventually grow a patch of watermelons in the garden. 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.

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". She weighs 29 kilograms, stands at 139cm and her wing type is listed as "Not Variable" and "Stealth". Because of this, Nymph can completely conceal her wings unlike Ikaros. She is originally sent to return Ikaros to the "New World" (Synapse). However, because she is less powerful than Ikaros, she is unable to do so. She soon develops feelings for Tomoki 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.
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 displayed a new ability, a "fundamental partical-jamming system" called "Aphrodite". 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. Nymph has high processing capabilities and has high emotional control, but as a result she's low in raw power. She also has the most powerful radar of the three first-generation Angeloids; Ikaros has even stated that her own radar's proficiency cannot be compared with that of Nymph even though she was wingless at that time. It was stated by Nymph herself that her radar was a lot weaker at the time her wings had not grown back. Nymph is shown to have a sweet tooth; her appearances mostly show her snacking on chips and other snacks.

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. She weighs 48 kilograms, stands at 159 cm, and her wing type is stated to be "Not Variable" and "Super Acceleration". 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 Synapse to eliminate Nymph, she breaks off her chain and engages in combat with Chaos. She 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.
Astraea has been described as being the fastest of the Angeloids and having greater battle 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 "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 can create a shield that covers all angles. Also, Aegis L cannot be deployed for long periods of time due to its massive energy requirements.

Chaos is a "Second-Generation Angeloid, Type Epsilon" (第二世代エンジェロイドタイプε?) and the first major antagonist introduced after the man of Synapse. Ironically the most miniature and child-like Angeloid, weighing 19 kilograms and being only 107 cm in height, she appears as a young child dressed in nun-like garments which can manipulate her appearance through elaborated illusions, mimicking someone dear to her victim in order to instill turmoil and confusion, as she did against Nymph by taking on the likeness of Tomoki. She lacks wings like other Angeloids, sporting a wicked array of bladed, almost organic-like appendages which act as an offensive weapon. 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.
Chaos first appeared to torture Nymph, and then fought Ikaros, which 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 fishes to—in her own words, grow bigger—and show her "love" to everyone.

Hiyori is introduced as a second-year student at Tomoki's school. She has feelings for Tomoki and joins the New Continent Discovery Club just to get closer to him. In reality, Hiyori is an angel who was first seen when Sugata went to Synapse. She was inside some sort of a sleeping chamber that connected 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. Hiyori's presence has become a source of major discomfort for Sohara, Nymph, and Astraea. 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 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 "Second-Generation Angeloid, Type Zeta" armed with a khakkhara called "Demeter", which has the power to control the weather. 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 Continent Discovery Club, since she already accomplished her goal of getting close to Tomoki (even going so far as kissing him).

Pero si Ichigo entra a la pelea, Ikaros se va al lado de soul society y acaba con las demas (seh, fumada mia que siempre ha creido que si Ichigo e Ikaros se encontraran se enamorarian xDD)
