Description

After the surface of the world broke down, the city of Novus Aether floats in the sky, thanks to the prayers of the Holy Maiden. Years ago, when the Holy Maiden's prayer was interrupted, an incident known as the "Gran Forte" occurred, causing a portion of the land to fall and split the lower city into two, separated by a cliff.

In time, the lowest layer became the dwelling of all kinds of low-lives, people who lost much of their former lives during the "Gran Forte", becoming known as the "Prison". However, a contagious disease which causes people to grow wings has spread throughout the city, and a unit has been formed to deal with these people swiftly.

In this "Prison" resides Caim Astraea, a freelance ex-assassin who does odd jobs for his friends for money, refusing jobs that require him to kill people. During one request, Caim finds a girl who contracts the wing-disease, enveloped in a light that reminds Caim of the “Gran Forte” years ago...

Description

The protagonist of the story and a freelance ex-assassin who has adapted to the harsh life in the “Prison”. Originally a resident of the lower city, his life as he knew it completely changed when he lost his home and family as a child during the “Gran Forte”. Like many “Prison” residents, the incident proved traumatic for him, and he has forsaken much of what he had believed in during his harsh and relentless time as an assassin.

He buys Eustia from “The Noncorroding Gold Chains” after seeing her emit the characteristic purple light of the “Gran Forte” incident, believing she may hold the answers to the event that almost completely destroyed his life. He appears cold and unrelenting, but, as many of the heroines and characters note, he is a kind person at heart.

Description

Eris was also saved from having to be a prostitute after Caim bought her. She is now recognized as one of the best doctors in the area, regularly treating the men and prostitutes that work for “The Noncorroding Gold Chains”, although she believes her true profession to be Caim’s significant other. Tall, well-proportioned and beautiful (and a doctor to boot), Eris is extremely popular among the men in the area, although she has eyes only for Caim and is very curt and blunt to everyone else.

Caim wants nothing more than for Eris to treasure her freedom and live independently; Eris, however, wants nothing more than to belong to Caim and obey his every command. This creates a certain amount of tension between the two characters, and, later in the story, it is revealed there is more to this relationship than meets the eye…

Description

The title character, Eustia (everyone calls her Tia for short) was saved from having to work as a prostitute after Caim buys her. An orphan for as long as she could remember, Tia grew up under harsh conditions, having worked as a slave for a noble family before ending up in the “Prison”. <hidden by spoiler settings>

She is cheerful and optimistic, and she believes that there is a greater purpose to her life from the periodic dreams she sees. She is driven by a huge desire to help and bring happiness to others, especially Caim, whom she looks up to as the one who changed her bitter life up to that point for the better.

Description

The captain of the “Wing Hunters”, Fione has a very strong sense of responsibility and justice. As such, she clings on very strongly to her beliefs, which makes her come off as stubborn and inflexible. She is a very hard worker and devotes herself fully to her duties, and as such is disliked by the majority of “Prison” residents, sentiments she also shares back at them.

Fione’s personality gradually changes when she and Caim join forces to rid the “Prison” of a serial killer known as “Black Wings”. They get to know one another as the investigation proceeds, and her patronizing attitude towards the “Prison” residents disappears as she comes to understand their way of life.

Description

The current princess of Novus Aether and successor to the throne, Licia is a young, mischievous girl with little interest in the politics of her country, leaving the decision-making to the House of Nobles and its head, Gilbert. She is, however, very interested in what the “Prison” and the lower city are like (though she is terribly misinformed in this matter) and loves to do servant work such as hanging laundry and cooking.

Description

The current Saint, Irene the 29th is gifted with a way with words and incredible strength of faith. Originally a homeless girl, she met Larvia, who would become a sister figure to her, on the streets. The Church would eventually take them both under its wing; she was selected to be the new Saint, to offer constant prayer on behalf of everyone in Novus Aether, after Irene the 28th was executed for interrupting her prayer and causing the “Gran Forte”.

St. Irene the 29th professes to have heard the voice of the Angel in her dreams during a bout of sickness which also left her blind, which begged her to search for the Angel’s Child. She is hurt that the people around her don’t respect her nor believe in her, and as such she can get very confrontational and stubborn once her beliefs are challenged.
