Characters Main
Tomoki is a teenage boy who wants nothing more than a peaceful and quiet life in Sorami City. He has had recurring dreams of meeting an angel since childhood. Despite being a shameless pervert, a trait heavily influenced by his grandfather and mother, Tomoki is described as a kind and sincere person. He strives to make Ikaros and the resident Angeloids behave more like humans by having them not be so focused on obedience, and telling them to make their own decisions. He is usually drawn in chibi parameters, except when he is serious or relaxed. Tomoki occasionally uses a device that transforms him into a girl named .
The title character and main heroine of the series, Ikaros is a beautiful gynoid known as an Angeloid. are a series of gynoids from Synapse that have wings like Angels. They are programmed to serve their masters using a process called "imprinting", represented by neck collar and chain that extends to her chosen master's hand. Each Angeloid is designated with a letter of the Greek alphabet, and can be programmed with abilities and powers that are a function of three main parameters: battle capability, emotional control and processing capability. The Angeloids' names, weapons, and abilities are primarily derived from Greek gods and mythological figures. She falls from the sky at the beginning of the story. After Tomoki recovers her, she forms a bond with him and calls him master: the imprinting is symbolized by a chain from her collar to his hand. She has an expressionless face that makes the other characters wonder if she will ever smile. Her emotions develop slowly, due to her programmed setting of high battle abilities and high processing abilities but low emotional abilities. Despite this, she develops genuine feelings of love for Tomoki. She also goes along with any of his perverted schemes, and eventually burns up into nothing after carrying Tomoki to Synapse, showing him her smile for the first time. She and the others are later resurrected by Tomoki's final wish. Although she initially states she is a "Pet-Class" (entertainment-purposed) Angeloid, she is actually a "Strategic Battle-Class" Angeloid. In her previous visit to Earth as the , she destroys the Tower of Babel. In "Battle Mode", she employs: , an energy shield sphere; , which fires an array of energy projectiles from her wings; and , a bow that fires an arrow of mass destruction. In Uranus Queen mode, she can interface with massive weapons platform called the Uranus System (Hephastus System in the Funimation dub). In a later battle, she evolves into Ikaros Version II with "Dual Variable Wings" that boost her power. Her name comes from the Greek mythological character Icarus, a craftman's son who flew too close to the sun and fell from the sky.
Sohara is Tomoki's next door neighbor and childhood best friend. She gets annoyed whenever Tomoki acts in a lecherous manner and typically punishes him with a single karate chop. As a child, she was constantly ill and only had Tomoki as a friend. Despite all the punishment she dishes out to him, she secretly loves him, and has embarrassing lustful dreams about him.. She is good at sports, but struggles heavily with English (Spanish in the Funimation dub), and is a deadly cook when it comes to sunny-side up eggs. Eventually, Daedalus reveals that she created Sohara: the girl who died from a childhood illness was Daedalus's original avatar, and the girl who grew up with Tomoki was a clone she made so that he would not forget her.
Sugata is the leader of the at Tomoki's school. He is an eccentric explorer and scientist who enjoys hang-gliding and living in the wilderness. In the anime, he opens the episodes with some philosophical narrations which reference historical explorers such as Magellan and Columbus. He is best friends with Mikako Satsukitane, even though her constant sexual advances towards him irritate him beyond belief. He behaves in a generally deadpan manner unless it involves the "New World", or his family background. Prior to the events of the series, he is the son of a renowned political family. When his elder brother died from a hang-gliding accident, Eishiro takes blame and is disowned by his family. Leaving his younger brother the sole heir. Since then he has followed his elder brother's footsteps in discovering a "New World" as a way of atoning for his misdeed.
Mikako is an upperclassman to Tomoki and Mitsuki and the student body president. She is a childhood friend of Sugata, whom she calls "Ei-kun", and is the daughter of an influential yakuza boss in Sorami. She is manipulative, cunning, highly intelligent, athletic and sadistic. She initiates many schemes in the form of festival competitions that place Tomoki in humiliating situations for her amusement. Unlike Sohara and the Angeloids, she directs her romantic affections towards Sugata, and claims him during the mock wedding in the second anime season finale.
Nymph is an . She is introduced when she finds Ikaros on an errand and attacks her, then later mysteriously appears in Tomoki's living room where she casually snacks on chips. She has a condescending attitude towards humans, whom she refers to as "bugs", and she calls Angeloids by their types rather than their names. For example, she calls Ikaros "Alpha". Despite the attitude, she starts enjoying everyday life and her favorite hobby is eating snacks and watching soap operas. Nymph's original mission was to retrieve Ikaros and return her to Synapse, however, she is physically weaker than her and fails in the mission after awakening Ikaros's Uranus Queen ability, and is consequently heavily punished and abused. After spending time with Tomoki and his friends, she begins to like humans, and soon develops feelings for Tomoki, albeit in an aloof fashion. Nymph eventually betrays Synapse: in the manga she tries to surprise attack the Harpies, while in the anime she sides with Ikaros. In both cases, her wings are consequently ripped off by the Harpies, but Tomoki and friends manage to free her from her link to her master. The wings regenerate when she accepts Tomoki as her new master. After the regrowth, Nymph needs to go through an Imprinting process required for her master; she eventually asks Tomoki, but he refuses and states that he wants her to live freely. As an Electronic Warfare-type Angeloid, Nymph's allocation of abilities emphasize her high processing capabilities and high emotional control, but her raw battle power is set low. Nymph is able to hack computer systems as well as other Angeloids and even humans. She uses a device called the Dive Game which enables humans to enter each other's dreams and through Tomoki's dream, visit Synapse. Her "Stealth" wings appear sheer, unlike Ikaros's wings which can only retract to stubs, and she can use them as a radar. She can also fire a high-powered energy beam from her mouth called . During the battle with Angeloid Hiyori, Tomoki's encouragement allows her to upgrade her powers to , a "fundamental particle-jamming system" that she uses to hack and free Hiyori. She eventually faces Minos and self-destructs to destroy Zeus. Nymph is named after and based on the nature spirits of Greek myth.
Astraea is a large-breasted sent by Synapse to kill Tomoki. She is strong in combat and emotion compared to Ikaros, but because of that allocation, her weakness is her low processing power, and the other Angeloids consider her an idiot; this is affirmed when she bungles her multiple chances to kill Tomoki at the Buddhist temple, and later at the quiz show where she fails basic questions such as "what is 1+1". She is often famished because she does not know how to hunt or to obtain food by her own means; in one episode, she eats Sugata's fish bait. After spending time with Tomoki, she refuses Master's order to kill Nymph, and severs her own chain. Astraea has a good relationship with her senpai sisters. Astraea eventually realizes that she too has fallen in love with Tomoki, after Chaos questions her on the definition of love. In recent chapters, she becomes depressed from losing her weapon and shield, but is encouraged by Tomoki who tells her only she can decide whether or not she is useless. She then decides to rescue her younger sister, Chaos. According to Daedalus, Astraea is extremely quick and has great close-combat capabilities but is vulnerable to long-range attacks. She wields a super-oscillating photon blade called , which can even penetrate Ikaros's Aegis defense system. For defense, she uses , a shield that is more powerful than Ikaros's version, but guards a limited angle and can only be deployed for a short period. However, in her fight with Ikaros Melan, Astraea's sword and shield are destroyed. Towards the end of the story, she battles Chaos where she evolves her weapon and shield, and they both are killed. Astraea is named after the ancient Greek goddess Astraea, who was a goddess of justice that later became the constellations Virgo and Libra.
Hiyori is a second-year student at Tomoki's school whose story is detailed in Heaven's Lost Property the Movie: The Angeloid of Clockwork. She is deeply in love with Tomoki and joins the New World Discovery Club in order to get closer to him; however, it is implied he doesn't feel the same way for her, and only sees her as a friend. 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 is hesitant in letting her join his club, but welcomes her upon hearing the club would receive more funding. Tomoki puts Hiyori through a false initiation to assess her purity. Thus far, only Sugata, Nymph, and Ikaros are aware of Hiyori's true identity.
