Year 501,
The dawn of the era of destruction
The Underworld
....
Hatred, vengeance, envy, and malice are negative energies that become the source of darkness's power. All that energy had gathered for millions of thousands of years in a place far below. And it kept gathering until it formed a vessel for the soul of a Demon King, the ruler of the underworld shrouded in darkness.
During that time, the gathered darkness swirled, and caused a tremendously fierce storm. Fragments of black mana scattered, triggering seven other souls to form quickly until the perfect stage. They knelt, waiting with high respect for the harmony within that fierce storm to be completed.
Flashes and thunder struck. The ground trembled, feeling an immensely powerful force swirling above it. The swirling power floated, revealing the silhouette of the shadow of darkness itself. The King of demons. The ruler of the underworld. He had been born.
The storm slowly subsided. The black mist slowly disappeared. The vortex of darkness vanished. Now what could be seen was only a figure full of grandeur. Sharp eyes of deep crimson, smooth white hair accompanied by two red horns, and black feathered wings. That figure full of grandeur was their King; Leviathan Demonio.
His wingbeats weakened, his body slowly descending downward until the pressure of black mana became increasingly suffocating. Then, when his feet touched the ground for the first time, fear seemed to surge fiercely through every blood vessel. The darknesses of the world had created a terrifying creature like him. Ruin walked without expression, without a heart, that was his figure.
"Welcome, Master."
Seven great demons were born from those fragments of black mana. They gathered at seven points, then paid their respects. The demons whose darkness was no less dense. The black mana flowing in their bodies far exceeded Eternity rank, the highest rank in this world.
"I am Lucifer, the fallen star, greeting the Master, the great Demon King."
One foot stepped back slowly, and the body bowed with a hand supporting the chest. A charming curtsy from Lucifer, the first great demon. The charming demon with a butler's appearance that was his trademark. His hair was black with deep purple eyes like a gem of darkness amid rays of light. Once, he was an intelligent and beautiful angel, before the fall that turned him into a demon full of deceit and manipulation. A hundred years ago, his soul was sealed after his body was killed.
"Hm, Lucifer." Leviathan merely remained still, staring flatly at Lucifer.
"Call me Beelzebub, the ruin."
The demon struck his chest proudly. Displaying a wide smile until his row of white teeth was visible. Holding the second position among the great demons, and the first position for the reckless demon who loved causing commotion. He was an eccentric demon, with blonde hair combed upward and amber eyes. A rebel who disliked being controlled, but his loyalty to Leviathan had been ingrained since he was still in the form of a soul without a vessel.
Lucifer looked at Beelzebub with dislike, "Be polite to the Master, you tacky demon."
"Have you ever looked in the mirror, seeing how ridiculous your appearance is, Lucifer?" Beelzebub did not want to lose, looking down on Lucifer's appearance from top to bottom.
Lucifer's lips formed a laugh, "Your words show that your taste in clothing is very poor, oh narcissistic demon lord."
"Please stop your quarrel, oh Lords."
A melodious voice was heard interrupting. Footsteps stamped softly, silencing the atmosphere. The scent of roses was smelled as a gentle wind struck his body. A captivating appearance, like a sculpture carved by a skilled artist. His eyelashes were long and curled, his white skin was very smooth, his green eyes shone beautifully amid strands of pink hair. Compared to a demon, he looked like a pink lily in a greenhouse.
"Allow me to introduce myself, Asmodeus, the third handsome great demon." He performed a curtsy no less beautiful than Lucifer's. "Controlling human lust and desire is my specialty. Often, I make them commit murder for me. I can also do it to you." He added, charmingly and dignifiedly.
"Are you implying to make us kill each other, Asmodeus? Apparently your attitude is not as beautiful as your looks. How terrifying."
This time, the soft voice of a woman. Her appearance was beautiful and her white body was lovely. Looking into her eyes, one's eyes would feel as if seeing the glimmer of a blue sky, and the beauty of a blooming pink rose when seeing her hair. With her dazzling appearance, no one would guess that she was a demon who brought death.
Lucifer laughed amusedly at the words of Karya, the fourth great demon whose beauty was undeniable. "Terrifying? Are you making a joke?"
Karya walked slowly toward Lucifer, touching inch by inch of Lucifer's body that caught her attention. "You... Even after hundreds of years, your handsome looks haven't changed at all, have they, Lucifer." She looked up, gazing at the perfection in Lucifer, the fallen star.
Lucifer looked at Karya with disgust, and said, "Get away. If necessary, disappear." He forcefully pushed Karya away from him. He admitted that the woman of death was very beautiful, enough to make anyone fall into her trap.
Plak
Someone roughly brushed Lucifer's hand aside.
"Be gentle with a lady."
Amon spoke to Lucifer in a high tone. The fifth great demon stared with hostility toward Lucifer. Though he liked speaking violently, he was kind to women and the weak.
"If you dare act roughly again, I will make you lose your pride as the first great demon."
Amon pointed the war hammer he always carried, then displayed his mischievous smile of victory. The demon who liked showing off his well-proportioned bare-chested physique indeed had a slight dislike for Lucifer. The reason was their clashing appearances and personalities. Amon was a mischievous demon with red hair styled messily and golden eyes. His harsh attitude contrasted with Lucifer's charm.
"I hope you utter your last words before dying after being reborn." Lucifer said, annoyed, emitting black mana pressure no less tormenting than Leviathan's.
"You two are... so childish, aren't you?"
Belial, the sixth great demon, walked lazily toward Amon and Lucifer who were arguing. If you guessed he was a lazy demon who loved gambling, you'd be wrong. Though his appearance was inconsistent, there was one appearance he always wore. Namely, the appearance of a well-mannered kid with brown hair and dark green eyes, who loved deception and lies.
"Hah...?" Amon made his worst questioning face. "You love violence, huh?" He approached Belial with his fierce gaze.
Belial leaned his chest forward, challenging Amon. "What? Am I you?"
"Your speech is inaudible because it sounds like a sparrow's chirp, you know!"
"Oh, maybe it's just your hearing that's bad."
"Damn—"
—Ctas
Both Amon and Belial froze. So Lucifer was skilled with his hands too, it seemed. The first-rank demon cut off half of both their heads, leaving only the mouth part. His face? It was clear that the demon liked it. By what means exactly had that Demon previously been able to hold the position of the highest angel before his fall?
"Your hands are quick, Lucifer." Amon regrew his head with regeneration magic without an incantation.
"Noisy..! Noisy bastards...!"
A seven-year-old child who had been sleeping since his appearance hissed. His light blue eyes were like diamonds amid his gently swaying white hair. A cute demon holding the seventh position among the great demons whose hobby was, lazing around, for example sleeping. He believed that this world was meaningless and it would be better to destroy it.
"Can't you adults be quiet when a child is sleeping?"
Belphegor. The magic that created the illusionary bed disappeared, forcing him to stand on both feet with his arms crossed over his chest. His face was sour, he felt like exploding to destroy everything so there would be no more noise.
Karya bowed, "Oh my, oh my." She gently poked Belphegor's cheek because she found him, who loved sleeping so much, adorable.
Belphegor brushed Karya's hand away. "Get your dirty hands off my face. It's disgusting." He requested, curtly.
"Can't you all stop?" asked Belial as he reattached the upper part of his head that had been cut off by Lucifer. "Aren't you ashamed to have such a childish quarrel in front of the Master?"
"I don't want to hear that from you." Amon made an annoyed face.
"Stop. We must do it now." Lucifer interjected, making them turn before nodding in understanding.
"Alright."
The quarrel that had just occurred seemed to have never happened as they united to combine their power, summoning a place long forgotten by the will of the world that wanted to balance darkness and light again. Therefore, with the power of the world's key; surge, castrum tenebrosum magnifucum!
The ground trembled again until it started a tremendous crack. Wall after wall emerged from the deep ground, forming a magnificent palace shrouded in black mana of darkness. The lower-class demons saw how the palace stood from their respective places, marking the return of the era of darkness standing alongside light.
"Please, Master."
The seven great demons lined up and then bowed respectfully, inviting Leviathan to step toward the throne room of his grandeur as the Demon King of the underworld. The seat gleaming with darkness was sat upon with the charisma of a King, creating a tremendous mana vibration that was felt even in the world above filled with light.
Lucifer stood proudly at the front of the line, looking toward the crowd of demons bustling below. Their appearance was the same as humans, except they had horns that distinguished them from the human race. "Welcome and praise your King, who balances light and darkness. If you have any objection, come and meet me directly." He shouted.
The demons below cheered, not a single one of them showed objection. Living in darkness that was always defeated by light felt suffocating. But now, thanks to the birth of the Demon King, darkness could balance with light. Cheers of praise were shown with extremely happy faces.
