Intro
"──This time, I will. Without fail."
It is a nightmare the four of them see over and over.
A castle engulfed in flames. The royal palace crumbling down. Stone pavements stained with blood.
The one and only princess they swore to protect was captured by the enemy before their eyes and quietly drew her last breath.
