Welcome to a world where humans and mecha co-exist. What was once thought to be a symbiotic relationship between humans and machines has turned into a full-scale war due to rising resentment by their human creators. In one of the towns, a 13-year-old boy named Burn will find out the true meaning of horror. Burn has not a care in the world, happily playing with his friends while his family watches the setting sun, until that happy reality is shattered by the arrival of an angel of death. This is the beginning of the end. The arrival of the sentient Shoftiel, a machine programmed to destroy mankind, will forever link the two in a battle of fates. One action, one desperate act of self-preservation will forever change the fate of man and machine.
