When he was young, Kyoutarou wanted to read all the magic books in the world, but they were all in the magic library. Someone told him that to get there, he must be kind to everyone and bring happiness to their hearts. He received a bookmark, which was his entrance ticket to the magic library. One day while heading to school, he received a text from the ‘shepherd’ (hitsujikai) telling him that his fate was going to change. He had a vision of an accident at the tram station and helped prevent any injuries by calling away a nearby girl. That girl, Tsugumi, later came to the Library Club room, which he was a member of, to thank him and also to ask for his help to make Shiomi Academy more fun. It seemed that she had also received a text from the shepherd, who is rumoured to appear before people who try their best to grant their wishes. One by one, other students also join their group with the shepherd’s guidance.

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...
