Kaminaki Sekai no Kamisama Katsudou

Under the belief that the omnipotent god Mitama will come to save him, Yukito Urabe participates in a ritual to become the new leader of his father's cult. But when the boy drowns during the ritual, he wishes to be reborn in a world without gods or religion. Reawakening in a completely different world devoid of spirituality. He meets a deviant girl named Aruaru, who introduces him to her village. However, his idyllic image of this world's society is short-lived when he witnesses a public group suicide and learns of the country's end-of-life system: at any moment, the government may order any citizen to die. Aruaru and her sister are forcibly taken for execution soon after, prompting Yukito to rush to their rescue—but to no avail. In a moment of desperation, Yukito recalls his father's teachings and utters a prayer for Mitama to save them. Seemingly answering his call, a little girl descends from the sky and annihilates everyone who harmed Yukito and his friends. To Yukito's surprise, the girl introduces herself as Mitama. Yukitos parents are the leaders of a cult. After he gets sacrificed, he gets reincarnated into another world where religion doesnt exist and porn books are akin to a childs doodles. He finds that its also a world where your life and death is decided by the country. While obstructing his friends execution, both of them lose their lives. Just at that moment, the god of his religion comes to their world and revives them.
