Meet Rin Asogi, a detective who never ages and enjoys nothing more than a good vodka. Unfortunately for Rin, she has a habit of attracting creatures that lurk in the darkness. For over sixty-five years, Rin has suffered through countless nightmares in which her body is savagely mutilated and destroyed. All of this torment is the result of Apos, a being who's consumed with sacrificing Rin to the Yggdrasil, the tree of all life. As Rin tries to uncover the sinister mystery behind her eternal pain, Apos waits in the shadows, eagerly craving to consume the memories of her many lives. Rin is no stranger to death and the afterlife, but the next time she visits, it might be forever.
