Black Beast (black dog): Corruption of Noble Warrior Women / Kuroinu: Kedakaki Seijo wa Hakudaku ni Somaru

In one country there is a nation Eostia, which has existed longer than others. At the same time, in the north of the country live terrible monsters called to destroy it. The evil of Eostia has spread over the country for many years. Many people suffered from monsters. But after numerous wars everything changed, and war was declared on the monsters. Seven warrior knights from different states decided to change the order of things in this country, and together with the goddess of the high elves formed the "Order of Courage". In a fortress known as the "Black Citadel", somewhere deep underground, a barrier was created that protected the castle from outsiders. Because of it, the sky turned red, day and night were indistinguishable, and the air was hard to breathe. The lands around the castle slowly died out, and no one could do anything about it. There were rumors that the castle was ruled by a beautiful dark elf known as the "Black Queen".

During the war, many mercenaries tried to defeat the "Army of Light". Fighting only for money, and spending all the money on entertainment. However, one day a man came who gathered all the mercenaries into a large army. His name was Vult. How the world will change after his arrival and what will happen to the "Order of Courage", time will tell...
