Two hundred years ago, mysterious ore-like beings called Resetters appeared and dismantled the world humanity had built. Their protective field made conventional weapons useless. Humanity retreated to fortified cities while the Ashes Church developed a countermeasure: artificial girls called Dolls, equipped with black iron armament capable of engaging the Resetters directly. The counterattack begins. A mobile RPG about girls engineered for a war they did not choose.
