Once upon a time, in a world filled with darkness and despair, there was a group of young girls who were chosen to become heroes. They were tasked with the responsibility of fighting against the evil Vertex of the Void, an entity that threatened to consume everything in its path. Among these heroes was Yuuki Yuuna, a kind-hearted and determined girl who was willing to do whatever it took to protect her friends and her world.
