Intro
"──This time, I will. Without fail."
It is the nightmare the four of them see over and over again.
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 breathed her last.
Not one of them could protect her.

The four of them cannot look away,
