Ren Ayato, a seventeen year old NEET, wakes up in a fantasy world. He has no magic, no money, and no idea where he is. When he collapses from hunger, he's saved by Elina, a trainee nun. To repay her, he helps her search for a lost child. For the first time in years, a sincere "thank you" makes Ren feel a sense of worth. Elina offers him a second chance, inviting him to her church. But Ren doesn't know that a new world also means new dangers, and to survive, he'll have to face the darkness hidden within it.
