“Humanity will be destroyed by the "Demon King".” About a month earlier, 800 million lives had already been lost due to the indiscriminate and suspicious deaths that had occurred. God said that the phenomenon, known as “Soul Peeling,” was caused by the “Demon King,” who looked like an innocent little girl. Ten angels representing the human race are selected to stop the disaster, and the “holy war” between “mankind” and the “Demon King” begins. In this world in turmoil, only Kosaka Yuto knew the girl. She has been made an enemy of the world, and she is a weak existence reaching out for help. For the sake of one girl, he will battle against the whole world. (Source: Sneaker Bunko, translated)
