PREMISE

Four heroic women banded together to conquer the great demon.
They were Draco of the Sword, Namo of the Wise, Shabon of the Brave
And finally-----San-Frau of the Heroes.
Following a violent journey they arrived before the demon.

But at the precipice of glory, San-Frau asked her band:
"I wonder if what we do is truly right?"
They had committed genocide against weak, simple monsters.
They had treated fellow humans as slaves, too.
A hero's path should not be strewn with such evil deeds.
So... were they evil?

San-Frau said this to the others but, they were not disheartened.
They forge ahead to subjugate the demon, as was their destiny......

... or so they thought, but at the critical moment the demon cursed them.

What manner of misfortune awaits the damned heroes?
They do not yet know-----.
