About Brave Witches
The Neuroi, an enemy of mankind, suddenly appeared in Europe in the 1930s. Only girls equipped with special magical powers, known as Witches, could confront the Neuroi who were not destroyable with ordinary weapons.
In September 1944, the Neuroi nest was eradicated and safety was ensured in Western Europe. Meanwhile, the allied forces began their plan for an operation against the Neuroi in Central and Eastern Europe. An order to scramble is given to the 502nd Joint Fighter Wing, commonly known as the "Brave Witches" whose base is in Peterburg within the Orussian Empire.
