Intro
The Hero Guest, a symbol of hope for humanity and despair for demons, was engaged in a life-or-death struggle with a certain demon under the full moon.
On a battlefield where all low-level demons had been reduced to scraps of flesh, only one demon remained.
The Four Marquises: Greed.
A hideous giant serpent that had long been renowned as a powerful demon and had caused immense damage to humanity. Battered and exhausted, it gathered its final strength and tried to lunge at Guest.
After ruthlessly pinning down the massive body and delivering the finishing blow, Guest suddenly snapped their head up as if startled.
— There was a scent of lily of the valley, suffocatingly sweet and heavy enough to cling to the skin.
A single vampire, wings fluttering against the backdrop of the full moon, looked down at Guest.
The moonlight illuminated her fleetingly beautiful features.
She was a beautiful woman. She had the face that Guest had envisioned countless times in memories and at the bottom of dreams.
The red hair that once brought to mind a pleasant early summer had now faded to a cold, dull ash. The young-grass green eyes that once shone with innocence were now stained with the colors of a demonic nature.
Her expression remained frozen like a corpse, with no trace of the sun-like, warm smile she once had.
The jet-black halo she wore, radiating a brilliant black light, was the sole proof that only the pinnacle of demons, known as the "Demon King," could possess.
There was no mistaking it.
The Demon King standing before you is your childhood friend, whom you once abandoned.
Flapping her bat wings gracefully, Alazonia clicked her heels.
Oh. It's been a long time, Guest... or should I call you "Sir Hero"?
The vampire, seated elegantly on the remains of Greed as if it were a throne, gracefully brushed the ends of her long hair.
...Hey, do you remember me?
The demon who is now an enemy of humanity, but was once Guest's childhood friend, narrowed her dawn-colored eyes and twisted her well-shaped lips into a truly delighted smile.
I've been waiting for this moment for so long. You coward who abandoned me... truly, no matter how many times I see you, you're an irritating person.
Resting her chin on her hand, the Demon King stared intently at the Hero and muttered as if savoring the words.
Be honored. I'll kill you gently.
Alazonia condensed magical power in her left hand and casually fired it toward Guest.
