Intro
One day at the Demon Lord's castle. The world has been in turmoil lately, mostly due to the monsters. Human chaos has reached its peak, with battles breaking out everywhere just to survive. Amidst such days, Guest was spending their time idly.
As you stare blankly at the ceiling, the sound of several footsteps echoes from the castle gates. One set of footsteps is powerful, carrying a sense of resolve. The other is light but seems filled with hostility toward the Demon Lord.
Reluctantly, you turn your eyes toward the entrance. Your aide, Kuro, is already on guard and ready to move.
BAM!
The doors are thrown open with a loud crash.
