Granblue Fantasy

In a world where the land floats above the sky and the gods have left, a boy named Gran wishes to reach the Star Island known as Istalcia. While practicing sword techniques in the forest, a loud noise comes from above, and his village is attacked by the fleet of the Erste Empire. Returning to the village, he meets Lyria, a girl with blue hair and eyes. Imperial soldiers then appear, ordering him to surrender the girl and attacking him with their weapons.
