Jun and her brother Nao are two unremarkable faces in a sea of nobodies. Struggling to climb toward a better future in a city filled with greed, violence, and corruption was already hard enough on its own. However, when the pair find themselves mixed up in the schemes of the undercity, they'll see their lives inexplicably changed. Finding work is suddenly a problem of yesterday's worry. Tomorrow's threats involve demons, dark mages, and their own borrowed time.
