Kamikatsu, What God Does in a World Without Gods

Yukito's parents are the leaders of a cult. After he gets sacrificed, he gets reincarnated into another world where religion doesn't exist and porn books are akin to a child's doodles. He finds that it's also a world where your life and death is decided by the country. While obstructing his friend's execution, both of them lose their lives. Just at that moment, the god of his religion comes to their world and revives them.
