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.

The title character (she is "Heaven's Lost Property") and main heroine of the series, Ikaros is a beautiful gynoid known as an "Angeloid". 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. Although she initially states she is a "Pet-Class" (entertainment-purposed) Angeloid, she is actually a "Strategic Battle-Class" Angeloid. Her name comes from the Greek mythological character Icarus, a craftsman's son who flew too close to the sun and fell from the sky.

Nymph is an "Electronic Warfare Angeloid, Type Beta". 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. After spending more time with Tomoki and his friends, she begins to like humans, and soon develops feelings for Tomoki, albeit in an aloof fashion. Nymph is named after and based on the nature spirits of the Greek mythology. Nymph's original mission was to retrieve Ikaros and return her to Synapse.
