To begin, we have the emergence of formidable adversaries known as the Enemies, invincible beasts that cannot be reasoned with. These foes threaten the survival of humanity. In response, a young boy employs a strategy involving moonfall, which halts their advance. However, he vanishes shortly thereafter. Three years later, another youth named Kyle Kamishiro emerges on the outskirts of a city. When monsters attack again, Kyle demonstrates his ability to manipulate probabilities. Despite his success, he is subsequently enlisted into the "Guilty Children," a team of young offenders.
