In the near future, 23 year-old apprentice nurse Lily Barrett lives in a shattered time. Following its economic collapse, the US has devolved into a group of a few barely-functional smaller states, and vast swathes of barbarian badlands. Her sister has been missing for years, and her father, after earning the opprobrium of most of the world for running a state terror organization, presumed dead.
Two things keep her going: her live-in job at a small, Catholic orphanage in the city of Waxahachie, Republic of Texas, and Ai, her odd, but dear friend, whom she met online: a young woman who only shows herself to Lily as a rendered CG image.
Troubled by her past, haunted by her name, and facing an uncertain future, Lily seeks only a quiet, normal life. But, that past and her present conspire against her.
