A group of people travels though a destroyed land of Earth called "Saint Michael" where they origin from, after a devastating distaster completely killed the whole humanity and nature, replacing humans with creatures and demons rised from the undergroud, and a black and destructed landscape all over the world, leaving a group of adolescents left. As they go on in their trip, they discover different people, whose some are friends who later join the group, and others are enemies where they will need to fight if they want to move on, and slowly get stronger and manage their super-powers better. They'll have to fight against many creatures as they progress in their trip, as the monsters also get stronger and harder to beat. A few of them die in the way, but also regain a few members along the way too. The more they progress in the trip, the more they discover, and try to go in depth and search for the reason of the disaster, until they reach the end, and find about the disgusting truth behind all everything...
