God took seven days to create the world, but regretted creating humanity. He destroyed the language people once shared, scattering them across the world, where they turned on one another and fought to the death.
In this world forsaken by God, a girl takes up arms and charges across battlefields filled with gunfire. Is she a messenger announcing the birth of a new god, or a godslayer who has come to stop God from controlling the world once more?
Bellit is a being born by accident. To fulfill the wish of his beloved, her father, Gazel, extracted their genes and used cloning technology to create two babies, a boy and a girl. She was supposed to be one of the "spares." Once the experiment succeeded, she should have been destroyed. But at the very last moment, she awoke despite having only a 20% chance of survival, becoming the third child of the Grace family.
Born with a defect, she became the least favored child in the family. She should have lived an ordinary life, but fate's many designs led her down a path full of hardship.
Theme: If the world casts you aside, then trample it underfoot.
