Note: There will be some elements from various popular games but not enough to be considered crossover(s), cameos at best. Set in DxD so my OC must have a harem but whether he genuinely loves them or not is debatable.
~Prologue, First Half~
Satanael was a middle-class Angel assigned to be in Archangel Gabriel's personal Legion. He was a very hardworking Angel to repay the Almighty for his kindness and the Archangel herself for her acceptance him into the Legion. Due to his below average physical health, he was ranked 987th of 1000 Angels and could only do mediocre tasks such as bring weapons for the higher ranks or do errands for Gabriel but he was happy with it. Even the Lady herself had been calling him for such things lately so he knew that he would be promoted soon and Satanael could finally purge the demons in the name of his Lady and God.
Satanael disgusted at himself for ever harboring feelings toward Lady Gabriel other than respect and loyalty. He secretly consulted this matter with the so-called Master of Love that he heard from the gossiping fellows, Samael. The suspicious-looking Archangel explained to him that the feeling was called 'love' and briefed him with a sizable information about such emotion. Satanael almost yelled out that doing such thing was a great sin and guaranteed to 'Fall'.
"You will be fine. No one gets fallen just by confessing his love, my boy Satanael. Just look at your fellow brothers."
Satanel frowned but nodded at his words nonetheless.
"Don't worry my boy. I will personally back you up." Samael used his enhanced vision to search for something. He smiled. "Gabriel is currently in the Sanctum with his Lordship, discussing. Wait until the Lord is gone and do it. I will follow you right away."
Satanael bowed at the Archangel and made his way. When he was out of earshot, Samael let out a malicious grin.
"…My Lady."
"Ah it's you, Satanael. What's the matter?" Gabriel beamed the usual kind smile of hers to Satanael. The latter felt like his heart skip a beat in that moment before speaking with all his courage.
"It is considered a sin to do this but." His eyes closed shut. "I love you, my lady Gabriel."
The Archangel gasped in surprise and embarrassment at the confession. She could not find any words to say. Satanael continued.
"It is perfectly fine to turn me down, my Lady. I am already prepared my heart for it and I am willing to take any punishments –"
"And that's what I am about to do right now."
Samael appeared with a group of guards and said. Behind him was the God Almighty himself and a furious Raphael drawing the Sword of Judgment. Both Satanael and Gabriel stared at them dumbfounded before the guards moved to apprehend the former and Raphael stood before the latter protectively.
"Satanael, how could you plot to, pardon my language, rape your Ladyship and make her Fall with you?" Samael asked with a mock disapproving expression. The Angel in question was confused.
"But my Lord, I don't know what 'rape' is. How can I do such thing to lady Gabriel?" He inquired with a straight face. Raphael almost murdered him before his Father stopped him with a look.
"Don't you dare joke with me, scum!" Raphael snarled. Samael faked a frown at his brother while walking toward Satanael and whispering something to him. His eyes widened in shock as he forced himself to kneel despite the restrains from the guards.
"My Lord, I did not attempt to do such blasphemous and disgusting action towards Lady Gabriel! I have served her with my utmost dedication and not once have I harbored such thought!"
"My son, I am very disappointed. Attempting to violate my daughter is already grievous and now lies? You have sunken too much now Satanael. Samael, if you may."
"Understood, Father." Samael showed a projection of Satanael's earlier meeting with the Archangel but something was very wrong. He was spouting words about his desire to rape Gabriel and Samael was trying to advise him against it but he didn't listen and storm away. He was silent, trying to digest the screen before realization dawned on his face. He lunged at Samael with a roar.
"HOW DARE YOU SET ME UP?!"
"Tsk tsk, how the noble and ever diligent Satanael has fallen." Samael sighed. "Do you see that, Father? This proves that even the most trusted and considered to be incorruptible can be corrupted. We must act quickly or else it would be too late. And Sister."
He turned to Gabriel. "Thank you for your cooperation. Without you putting a façade, we could not catch this filth easily."
"W-What are you saying –"
"Don't tell me, your Ladyship conspired this with him too?!" Satanael looked at Gabriel with horror in his eyes, despite the latter trying to explain that she did not. God, at this moment, knew that something was wrong. He knew that Satanael, who was known as the Angel of Order and Loyalty, would not commit such heresy but without clear proves, he could not say anything. While Raphael demanded to let him handle the execution, Samael suggested the most merciful solution: cast him down to the mortal world.
"Hahaha…"
"What now, scum?!" Raphael shouted.
"HAHAHAHAHA! I understand it now!" Satanael suddenly yelled out with a maniac glee. "I have been a toy for you all to play with from the beginning. A weak but willing toy."
He dryly laughed. "Born without the necessary health to do his duty. Angel of Order doing errands like a fucking slave? Hah! You can no longer deceive me, O False God."
"Why you?!"
"You act like an innocent girl but in reality, you are a bitch in sheep's clothing, my Lady." Gabriel was almost to her knees at the accusation.
"That's it, I will tear your body apart heretic!"
"No need! I will do it myself." Satanael reached his wings and started pulling. The sound of flesh and bones being tore from his back sickened those present, even Samael. Despite the immense pain, he did not scream. Instead, his smirk kept growing until it became a slasher smile. The process was finished and he threw the bloodied wings, what defined an Angel, to the feet of God.
"I won't allow myself to be tainted with black. But I allow hatred and malice fill my heart and soul!"
"Stop, Satanael! I beg you, any more and you can no longer walk on Heaven again!"
"Shut you trap, Gabriel the Bitch!" Satanael snarled. He was one inch to the Pit, door to the Underworld. "Mark my words: I will train my body and then gather an army, a Legion of my own, to level this disgusting place before killing you all. Starting with you, dear Father."
"Satanael, I cannot tolerate your words anymore. I banish you to the Pandemonium and forever get trapped in there!"
"So be it! And I shall be Satanael no more. I am Satan, and I shall get my revenge no matter how long it takes!" He yelled to the sky before taking a step and falling into the dark pitch depth below.
For a hundred years, Satan had pushed his body to limit and eventually became powerful, so powerful that he wiped out the devils with one flick of his hand. He met a demoness called Leviathan after saving her from an Angel patrol and she swore her loyalty to him despite knowing his true identity thanks to her power. A master of mind and ice magic she proclaimed and he tested them himself. Satan was pleased.
Satan and Leviathan gathered up a small warband to conquer the other warlords and assimilated their armies. Soon, he recruited the brilliant tactician Beelzebub and the master of stealth Asmodeus. The latter also carried the job to recruit more Devils into their cause.
A short time later, Underworld was 90% under Satan's leadership. But he did not satisfy. Satan needed more than just his current power in order to slay the wrenched God and his children. So he began to seek out those who possessed extraordinary abilities and defeat them to gain their powers. Eventually, he gained the total of twenty different abilities that would help him slay the Archangel of Might during his arrival at Underworld to search for Satan, or rather, Satanael. The essence of Zeruel was then absorbed into his blade and one swing of it almost split the barrier between realms. Like Satan would need it though since with his current abilities, he could kill the highest of the Archangels and at least incapacitate God easily but he always brought it with him all the time.
…
Satan stared dumbfounded at Helel, his eldest brother, or what Helel had become. Alongside him was a very large number of Blackened Angels or as Asmodeus said, Fallen Angels. Much to his delight, Samael was among them. But personal vendetta later, he had to ask Helel.
"Brother, what sin did you commit to get casted down to the Underworld?"
"He asked us to bow to them." Helel spat out venomously. "We, the Angels, have to bow to monkeys? Ridiculous!"
"Ah I see." Satan chuckled while taking a good look at the Black Angels in the front row. "Azazel, what could possibly make a brilliant individual like you fall? Certainly you don't care about His decisions and all."
"Um, well, that is a personal question that I would like to answer in an appropriate time." Azazel said meekly, causing his two subordinates to laugh slightly. Satan somehow understood the undertone and nodded wholeheartedly.
"Oh well, what is done is done. Come, let us find a suitable place for you all to stay!" Satan said with a smile. He turned to his newly found general, Lucifer. "I can trust you with this task, Lucifer?"
"With my pleasure, my lord."
"Good. Now, my brothers, let us head toward my castle. You all must be hungry after all!"
I won't be focusing in the Great War much since my current idea only covers up to two chapters at best. Satanael's shift of personality can be explained by exposing too long for a certain magic and combining with his hatred, it is miracle that he does not go full insane.
Stay tuned for the second and the final part of the Prologue guys!
