Note: Satanael's original title is Seraphim of Order, after demotion, Angel of Order. Satan's title is King of Ruin, Destruction and Despair. His more common ones are Overlord of Underworld, Unmatched King of Hell, Emperor of Pandemonium or just plain King of Hell.
~Prologue, Second Half~
Lucifer found a secluded and mountainous area for the Fallen Angels. His Lord suggested a closer one so that he could visit his brothers frequently but the majority of his generals and troops still hated the Angels, regardless of their current state. Helel let his subordinate Azazel handle the construction of their new base while the Morning Star stayed to offer an alliance with the Devils. Satan wholeheartedly agreed as if it was a norm. But then his face crept a maniac glee, the same one Helel had witnessed at the moment that Satanael 'died' long ago.
"Leave Samael here to me. I have so many things to do with him."
"Samael is punished for the trickery he has pulled for millennia, including your Fall. Father sent Zeruel to bring you back, He even erased your sentence –"
"NEVER MENTION THAT FALSE GOD IN MY FACE AGAIN!" Satan roared as the glasses in the hall shattered. The Fellsword of Damnation almost cleaved the building in perfectly clean half if Beelzebub didn't snatch it from his lord. Satan snarled at his general when Leviathan used her magic to ease his mind.
"Ah yes yes…" Satan said to himself with a small smile as he sat down, hands waving to cast a spell that repaired the damage he had caused earlier. Helel was unnerved by the hatred he saw in his brother's heart when he tried to take a peek inside Satan's consciousness. No wonder he became so powerful right now, his rage fueled his willpower to overcome his weakness.
"In second thought, I have a better idea. How about this…" Helel whispered to Satan's ear and the latter chuckled.
"Good good, it sounds good. As much as I want to chew his body to the last bone, I guess my appetite must wait. As of that matter, I'm afraid that we have to postpone that until your army is well-prepared. For now, we the Devils will keep raiding on every Heaven outpost we found to reduce their troops on both Underworld and the land of mortals."
Satan snapped his fingers as Beelzebub brought out a large and detailed map on the table. There were many 'X' marks and various symbols on it. He frowned and turned to his general.
"How many times did I have to remind you to replace this piece of paper with a new one with only a black mark on each of the conquered areas?!"
"B-But this is the only completed map we ever have in the Underworld, at least until now!"
"…Seriously? Asmodeus, send Corvus and his Company, alongside the other fastest units available to spread out and try to memorize every single area in our sector, excluding the ones that too secluded or within the territory of the Fallen Angels." He turned to Helel. "Brother, tell Azazel to meet up with me as soon as possible. We will need his legion's help to expand the map too."
"That I can arrange, Satanael." Helel nodded curtly while Asmodeus excused himself to meet his underlings.
"Good. Well then, we warp this up for now. Lucifer, lead my brother to the region that you chose for his army. Remember to watch out for those chickens, lately they have Cherudim-class among them. You cannot handle ten or more of them easily."
"Understood. Lord Helel, if you may."
Helel said goodbye to Satan and his generals before following. Satan then frowned at the mess of a map. A question mark was placed on the spacious plain area with the word 'Bael' displayed near it. The Bael was a proud and arrogant clan, even after he killed their leader due to their flat-out insulting his general, Levithan, for her failure of a clan leader. He didn't divert much into each of his subordinate's background, as long as they were loyal to him, he was fine with them all.
"It is the Bael, isn't it my lord?" Leviathan inquired with a worried look. Satan nodded slightly as he massaged his temple.
"They are the most stubborn bunch I have ever met since my arrival at this realm. Granted that I can easily wipe them out of the earth for their attitudes toward you," Leviathan blushed heavily. "but that would demoralize our troops and then lead to unfavorable scenario. After all, the Bael is the largest warlord until my rise. Beelzebub, do you have any suggestion? The Armageddon is near, but we can't even unite our own people then how can we stand against those pretentious bastards?"
The man in question started calculating the possibilities. Leaving the tactician, Satan summoned a portal leading to his personal training ground. Today, he must master the Art of Time from the book that he borrowed from the Agares clan. Two hours later, Beelzebub ran so fast as if his life was on the thread to Satan's chamber, right during his first successful cast of the Time Stop ability.
"My lord! The Bael, they – Oh shit!"
"Beelzebub, you foooooooooooool –"
Needless to say, the guards were panic to find the duo frozen mid-air with terror in their faces. Leviathan had to call for Lord Agares to unfreeze them.
"Ahem…" Leviathan coughed at the King of Ruin who was busy kicking his subordinate's butt, literally, for the accident earlier. The representative from the Bael clan tried his best not to laugh.
"You idiot! Don't your parents teach you how to knock the door?!"
"I-I am very sorry, my lord! It was urgent so I – Ouch, forgive me my lord!"
At that moment, Azazel happened to arrive as well. He was mortified to see a once the Angel of Order now was hitting his underling in a serious yet comical manner. Satan seemed to recognize the presence of his brother. He promptly delivered one last kick to Beelzebub and then regained his composure like nothing had happened.
"Beelzebub, pick your ass up and deal with the Bael man for the time being, my meeting with brother Azazel is utmost personal."
"A-At once, my lord! Ouch…"
"Good. Come, my brother. We will speak in my room."
…
"Brother, why so soon? I thought the construction should be taking at least one week to finish the basic structure, especially in that kind of terrain."
"My dear brother, you vastly underestimated my crew. Did you forget that my legion is among the best in this field back in Heaven." Azazel smugly said.
"Hahaha, indeed. But into the business, why the hell are you even Fallen, brother Azazel? You are not the type to sink into the sinful desires nor get into a mess like I did. The False God even granted you the privilege to access the most forbidden scriptures for inspiration!"
"Um, well, I was caught red-handed while doing ecchi with a mortal girl…"
"Ecchi?"
"You know, sex stuff. And I am sorry to say this but I have always had those perverted thoughts in my head and when I met that girl, I could not resist and a voice in my heart told me to go for it and…I did it."
Satan was speechless and was doing some incomprehensible actions to describe his thoughts. Azazel knew of Satanael's great respect to his fellow brother, except Samael of course, and now one of them got fallen for a trivial reason like that. Then he laughed.
"Good! You have done a great job!"
"What are you saying brother?"
"You follow what your heart tells, that is freedom. The False God keeps suppressing our true selves so that we are just puppets for him to play and toy with! A dog that does his biddings!" And then he stopped laughing. "Unlike me, I did my task just like my heart told me to, and then I got manipulated and then thrown away like a broken doll! From the beginning, I knew that something was very wrong with my body. Even a low-class can beat me in combat, you heard it, a LOW-LEVEL! Defeated! A MID-LEVEL!"
Azazel nodded grimly. It was a secret among the high-ranking Angels that Satanael was God's second son after Helel, but for whatever reasons his memories was wiped and demoted from Seraphim, the highest position that Helel and Metatron belonged to, to a Mid-Level Angel with majority of his strength sealed. God created Helel to lead the Angels while Satanael was his Sword to strike down enemies. Azazel knew for a fact that the seal had not been broken at all and Satanael was this strong already. Ooh Michael and his siblings would not like this when he set his foots once again in Heaven. Azazel waited until Satan ended his rant and calmed down to speak.
"Oh well, what is done is done. While I don't like fighting much, I will surely lend a hand in the Armageddon to you, brother." He remembered seeing Leviathan standing with Satan. A fine lady she was. Azazel decided to tease Satan.
"You know, brother, you did a good job at forgetting Gabriel and went for that female subordinate of yours. I feel so proud of you!"
"Ah, that." Satan dryly laughed. "I lost my ability to love not too long ago. When I fell to this place, I was weak. I was chased around by the weakest of the Devils. I was powerless and I loathed the weakness that got me in this situation. So I let hatred consumed my heart, and let it eat away the useless emotion that called 'Love'. I am well aware of the feelings Leviathan has for me but it is no use, I am currently incapable of feeling 'love'."
"Oh you poor thing…" Azazel muttered with a sad smile as he pitied Gabriel and prayed that once Satan entered Heaven, he would not murder her in cold blood.
A few serious talks later and Azazel tried to lighten the atmosphere by reminding Satan of the fun memories and his misadventures in the mortal world. The Overlord laughed lightheartedly and called the servants to bring out wines and foods until Leviathan 'politely' admonished him that there was still the representative of the Bael clan waiting for him. Satan blinked his eyes twice before coughing.
"Ahem, well brother, it seems that I have other matters to attend. Please make yourself at home. I will be right back."
Turned out the straight face that old man Bael had made back then was a front to save face for the clan since Satan effortlessly tanked the Power of Destruction blast from Lord Bael and then obliterated him completely with a gravitational beam that Satan dubbed 'Graviton Blaster', which eventually became the Overlord of Hell's signature attack along with the gigantic magic glyph that rained down destructive beams called Raintive Orion, although he knew a vast amount of spells and attacks alike.
"An alliance without any terms? Do you take me a fool?"
"Technically there is none, but in my understanding of his nature, lord Zekram Bael wants a high seat in the government in return."
Asmodeus, who had just returned from the assignment, commented, almost making the representative's heart stop beating due to how accurate it was. Satan smirked devilishly as he opened his palm to reveal a pitch black energy sphere.
"Mr. Representative, do you know what this is?"
"S-Sir, it's the infamous Graviton Blaster. Please don't kill me!"
"Oh no, I won't. I am rather pleased with your presence here, bringing the news to me. Otherwise, when I am out with my army, who knows what that old geezer is gonna do. No, Mr. Representative, this is for Zekram Bael himself. I have deployed a sizable orbital formation of Graviton Spheres above the territory of the Bael. One snap and the area will become a wasteland along with your master. Now, the question is," He stared into the poor Devil's eyes with a crazed glee. "Will you spit out everything I need to know, or I may kill you as well."
And the Devil said everything. Apparently Zekram would, indeed, use Satan's absence during the upcoming Armageddon to usurp his rule and if he survived, Zekram would assassinate him. Lucifer was furious and demanded to lead a legion to deliver judgment upon Bael but Satan waved it off with a lax smile. He sent a servant to escort the Representative and then he revealed his agenda.
"I have anticipated this from the beginning. I am no pureblood Devil by all means, yet I am ruling the entire Underworld, which is an eyesore to a proud pureblood like Zekram Bael. Countermeasures have been made so Lucifer, you can go back to your daily duty. No need to think so much."
"I, I… Understood, my lord." Lucifer reluctantly obeyed and left the hall. Azazel chose this moment to enter.
"Brother, have you gotten fed of foods and drinks already?"
"Nah, they are great but I'm afraid that I still have my own duty to attend."
Satan laughed as he patted his brother's back affectionately. He personally escorted the Fallen Angel to the entrance.
"Brother, send Baraqiel and Shemyaza my regards. Armageddon is still far from now so just relax and enjoy your new home. I will visit you as soon as I can."
Time passed as the Fallen Angels adapted to the Underworld and joined hands with the Devils to influence the mortal worlds with their devious ideals. Satan, however, banned his people from having the humans worship him, as he loathed any prayers that the 'children of God' made for him.
Back in Heaven, Gabriel had been guarded closely to prevent her from going to the Underworld to meet Satanael but one of her gifted powers from God showed a vision where the forces of Devils, Fallen Angels and Angels fought against each other and then Satanael was the one who murdered his Father, ending the war. She warned God of this and while occupied by a different vision, He still amassed his army, waiting for that day.
…
Helel had a similar vision but it showed his death at Michael's hand. His visions never lied. Helel consulted this with his closest subordinates and Satanael, of course.
"Can't it be changed? No way around?" Satanael, his most trusted brother even after he had become the King of Ruin, asked desperately. Azazel shook his head sadly. Helel managed to smile.
"I am going to die, true, but I want to make a glory last stand against Father and our former brethren. All of you, except Azazel and Satanael, leave us be." The other Fallen Angels complied and exited the giant hall. After making sure that there was no one eavesdropping, Helel confessed one more vision.
"During the Armageddon, some of my subordinates who still have the hatred toward Devils will lead a rebellion and turn on your army, Satanael."
"…Any notable name?"
"Kokabiel is among them. But do not confront him, not this soon. The vision showed me that he will be slain by the Red Dragon Emperor with the help of the White Dragon Emperor under the guidance of the King of Ruin, meaning you my brother. Azazel, your task is to minimize the damage as much as you can but still have to let the rebellion happen."
"I respect you, brother Helel, but I cannot fathom seeing my people getting slaughtered by some fools that you cannot control." Satanael scowled.
"I perfectly understand that, Satanael. But you must understand, there is an extra player in our world and they are watching us fight against each other like some sort of an entertainment. In the era where Kokabiel will be slayed, that faction will reveal themselves and you will destroy them with Satanael in my stead, Azazel."
The Black Angel in question was confused. Satanael sighed. "It means brother Helel makes you the next leader of the Grigori, Azazel."
"B-But Helel, I cannot accept such offer! I don't have the natural ability to lead like you and Satanael!"
"You can do it, Azazel. It would be difficult, but I believe under your leadership, the Grigori will become a powerful faction that can rival Heaven and even Hell." This made Satan snort.
"Is that a challenge, brother?"
"It definitely is." Three of them laughed, just like the old times.
And then, Armageddon finally came.
Satan mercilessly rained down on the helpless Angels who were unfortunate to get trapped within the white glyph of Raintive Orion, they even didn't get to scream as the beams vaporized their bodies completely. His army advanced with the support of the Fallen Angels from above and soon, they arrived at the Great Entrance. Greeting them was a large legion with Raphael, Michael, Uriel, Metatron and the other high-ranking Archangels.
"You will step no more into the sacred sanctum of God!" Raphael declared as he drew his Sword of Judgment.
"Satanael, how dare you show up here after murdering Zeruel?! Does your heresy know no bounds?!" Uriel shouted with anger in his voice. Satan replied was a maniac laughter that silenced the heated atmosphere. And then he snarled.
"HERESY?! IS IT A HERESY TO BE BORN WITH SO MUCH POWER THAT THE FALSE GOD HAS TO SEAL IT AWAY SO THAT I CANNOT USURP HIM?! IS IT A HERESY TO LOVE AND THEN GOT SCREWED LIKE A BROKEN DOLL?! IS IT A HERESY WHEN YOU HAVE TO SUPPRESS YOUR DESIRE JUST TO OBEY THE FALSE GOD LIKE A FUCKING PUPPET?!" Azazel nodded at the last question.
"It is our duty to obey Father! And don't you dare speak that name again!" Sandalphon yelled.
"I DARE! AND NOW, THE TYRANNICAL RULE OF THE FALSE GOD SHALL END HERE! MY ARMY, CHARGE! DESTROY EVERYTHING ON YOUR PATH –"
"Please stop this, Satanael! A gentle soul like you is not like this!" Gabriel pleaded desperately. Satan blinked at her while in the background, Leviathan muttered something between 'That bitch' and 'A whore'. And he laughed again.
"Oh damn, it is so hilarious!" The maniacal glee appeared again. "DO YOU THINK YOU HAVE THE RIGHT TO SAY THAT, HARLOT?! I WONDER WHO WAS YOUR NEXT VICTIM AFTER ME, IS IT REMIEL? SARIEL? OR EVEN BETTER, METATRON? NO MATTER!" He signaled Leviathan to come forward. "MY GENERAL LEVIATHAN WILL HAVE THE HONOR TO MANGLE YOU AND THEN YOUR CORPSE WILL BE A GREAT EXAMPLE FOR THE OTHER HARLOTS OUT THERE!"
Gabriel was too hurt to continue as she collapsed with her subordinates carrying her into the inner sanctum to recover.
"You will pay greatly for that, scum. All troops…!"
"Leviathan, remember not to kill her. Her survival is crucial in the prophecy, no matter how much you hate you, do not kill her. Understand?"
"…Crystal." Leviathan bit her lip to prevent her from cursing Gabriel before her lord.
"Good. Brother Helel, let's begin the feast. CHARGE!"
…
Satan brought his Fellsword upon Remiel and cleaved the Archangel in half before blasting away his remained warriors with the Graviton Blaster. He was close to the Seventh Heaven and he could feel the immense aura of God behind the gate. A heart-crushing feeling flashed across his head as Helel felt before Michael, just like in the vision. Satan let one single tear fall on his cheek and destroyed the gate with a kick.
"So you have returned, my son."
"Oh spare your honey words, father. I have come for your head, and the freedom of every creature – What…are you…?!"
Before him was a rotting Bible God with numerous runes, implying curses, on His holy body. Satan felt a surge of long-forgotten emotion in his heart as he made a run to his Father.
"What… How… When?!"
"Trihexa tried to materialize into the Realspace. I managed to put thousands of seals on it but it also managed to put countless cursed on me…"
"Stop talking! I will find Michael!"
"No… He will certainly kill you in sight. Listen here, Satanael, you must end my life or else the curses will take over me and force me to open the seals on the 666. It is also your intention from the beginning, correct?"
"But…But there is no glory in this! How can I face Helel if I do this?!" Satan shouted.
"Ah, Helel. He foresaw this and decided to take things into his hands by trying to defeat the Beast by himself, but got grievous injures in the result. And it was my own fault that drove him to Fall." Blood started dripping down from God's mouth as his body reached its critical point of toleration. Satan, no, Satanael gritted his teeth in anger and hopelessness as he reached his Fellsword of Damnation.
"Yes. Put an end to this miserable old man. Satanael, you may know that Samael was the one causing that event but I have a major fault as well…"
"Stop talking! Just…stop…" Tears flowing freely on his face as Satanael stood up, poured energy into the blade and held it above the heart position on the God. The latter closed his eyes, preparing to depart from this world but without saying his last.
"When things die down, meet Michael and he will show you the reason why I did those horrible things to you. And Satanael? I am proud of you, my son."
"AAAAAAAAARGH!" The Fellsword hit its target and the divine light of the Seventh Heaven dimmed down and then everything went dark.
The casualties from all sides were big. Despite Azazel's intervention, the rebelled Fallen Angels still managed to take many lives of their former allies and lost as many. All Four Generals of Satan were among the dead. Beelzebub fell to Raphael's blade, Asmodeus was stabbed to death by Sandalphon, Lucifer put a good fight against Metatron before succumbing to his wounds and Leviathan was the one to lose the final clash against Gabriel. Although the news of Satan slaying God was spread as fast as light could travel, the King of Ruin himself was also declared KIA. Therefore, no faction won in Armageddon. The survived generals of all sides signed a temporary ceasefire to avoid further bloodshed. Satan declared that once he was dead, his Four Generals of Satan would become the Four Great Satans and rule the Underworld altogether. The so-called Kings and Queen managed to keep Hell from falling to the invading Fallen Angels until the Civil War broke out. The Old-Satan Faction lost to the Resistance and a new generation of Four Great Satans came to rule the Underworld, promising to make it great like it had been under Satan's rule long time ago.
There was a peace, not technically a peace but still a peace, for a long time on the world. Nowadays, in Kuoh, a man with jet black hair, blood-red eyes and six demonic yet angelic wings descended on the local park. There was a Fallen Angel in the area who happened to see. He managed to utter one word and one sentence when he was obliterated by a gravitational blast.
"SATAN! SATAN IS BACK!"
So the Prologue is finally finished. Chapter 1 will be told in Satan(ael)'s FOV of course, but he won't steal the spotlight from the DxD cast, at least not the entire spotlight. He does have a Peerage but it won't function like a Peerage. Stay tuned!
