On the ruins of the Kingdom of Cappadocia, the shadows of the three evil gods have not yet dissipated.
Battle Sister Lilia Hill was ordered to wipe out the remnants of the evil god and sneaked into the eroded village alone. When she blasted open the mask of the false god with a firecracker, two girls who fell from the sky broke her peaceful mission - Cirno, who claimed to be the "genius ice spirit", and the mysterious white-haired girl Kaelia. They claimed to be from a foreign land and came to participate in the "holy war".
However, the evil god is not the only darkness in this land.
The cavalry of the Hitria Empire massacred compatriots in the name of eradication. The rescued villagers turned around and pushed their benefactors into monsters. The beautiful singer at the bottom of the well told about centuries of injustice and betrayal... When her faith was questioned and her goodwill was trampled on, Lilia had to re-examine everything she protected.
What is justice? What is evil? The apostle of the god raised the butcher knife, while the cursed monster shed tears - in this war, who is the light and who is the abyss?
A blunderbuss, a cross, and two companions of unknown origin. Lilia's holy war has just begun.
