It was not supposed to be like this. Amriel thought to herself as she lies on the ground bleeding out. She and her fellow angels were tasked with bringing God's blessings to humans, but she never would have expected devils to lurk and ambush them in a place where the worship of God is high.

"Any last words, angel scum?" the leader of the devils gloated, smirking as he raises his sword. "Haha, what am I saying, dogs of his will do not deserve any last words." he said while laughing manically as he is prepared to strike.

Crunch,suddenly a sound from behind the devils, alarmed the leader devil and his devil lackeys to stop what they were doing immediately, turning their attention away from the heavily injured angel, and towards what appeared to be a young devil girl with short purple hair, wings and tail. munching on what seems to be a bowl of popcorn of a things, while sitting on a metal frame chair, enjoying the spectacle before her, watching with a gremlin-like smile on her face.

"Who in Lucifer's name are you?" The leader devil demanded eyes burning red with rage, furious that his execution of one of God's bitches was interrupted, while his lackeys all got into a fighting stance ready to attack at the leader's first signal.

The girl who looks like she has not a care in the world about the angry devil, is currently stuffed mouth full of popcorn taking her precious time as she finishes chewing the snack then swallowing.

"Please ignore me, and carry on what you are doing." the girl requested nonchalantly. "The scene is good, but your evil laughter needs more work, I mean Haha, what type of evil laugh is that? Allow me to demonstrate a real evil laugh Muahahahahahahaha."

The devil leader stared at the laughing girl with a death glare, body shaking with anger ready to erupt. "How dare you turn my moment of triumph into a spectacle? And even worse make fun of my laughter, I'll have you know it's the evilest laughter aside from lord Lucifer's laughter himself."

The devil's leader's lackeys froze for a second there, all with one thought in their minds. Your more upset that about your admittedly terrible evil laugh then being made a spectacle?

"No one makes fun of my evil laugh, not even a child, minions attack, I'm going to have fun torturing you to death." The devil leader commanded while a sadistic smile starts to form on his face.

"Hold on just a minute sir." One of his more sensible lackeys interrupted with concern in his eyes. "This girl just appeared out of nowhere watching the entire time, none of us were able to sense her, isn't that an indication that she might be out of our league?"

Just as the other lackeys were about to consider the implications of what the sensible lacky suggested. The leader with no hesitation whatsoever proceeded to cut his lacky down.

"O, I am slain." the lacky crocked out, body dropping on the ground with a thud.

"I don't need a cowardly low-class devil to tell me what to do, let alone one that's afraid of some brat." The devil leader said angrily then turned towards his lackeys. "And if you don't want to end up like that clown, Attack right now."

Under the devil leader's threats, the devil lackeys rushed forward weapons drawn, all focused on cutting the girl down.

"Sigh, and I thought I could be a bystander, and not an actor in this scene." The Young girl said as she threw her bowl of popcorn at the fast-approaching lackeys temporarily blinding them and slowing them down, she then pulled out her chair from underneath her, folding it the chair now resembling a solid board, she then uses it to strike all the charging lackeys, creating a shockwave while painting the surroundings red in an instant, with mangled devil parts flying about.

"What, how?" The devil leader eyes now widen with fear, his body completely frozen and covered in the blood and bits of his former lackeys, knowing that he just fucked up as not even he could instantly kill all of his lackeys at once.

"Please have mercy, unknown high-ranking devil." The devil leader dropped down on his knees and begged eyes now watering with tears. "I was foolish and unaware of your power, it would be a pleasure for me to continue to be a clown in order to entertain you.

This statement seemed to make the young girl temporarily pause, one of her hands is seen placed on her chin in contemplation.

"Hmmm, you do have a point my enjoyment was taken from me."

"So does that mean?" The devil leader looked upon young devil with hope in his eyes.

"Yeah, I guess you can live for my enjoyment, I want to try what is it now that you said you will enjoy doing ..."

Not even before the young girl finish the sentence, the devil leader started to flap his wings rapidly shooting straight up in an attempt to escape, only for the girl to immediately appear in front of him wearing a sinister grin, knocking him down towards the ground creating a huge crater where they just were.

"Pls, senior devil, have mercy im sorr.. sorry." The devil leader crocked out incoherently as he coughed out blood, every bone in his body seemly broken due to the impact.
"Oh, don't be." The young girl said smiling as she approached the downed devil with her folding chair still in hand.

"You have given me such a great suggestion for my enjoyment, it's only fair you get to experience it firsthand." The young girl said as she brought the folding chair down hitting the downed devil hard, making more crunching bone sounds."

"AHHHHH" the devil screamed out in agony. "I'M SORRY PLEASE FORGIVE ME HIGH DEVIL."

"One more thing." The girl suddenly paused her strikes briefly giving the suffering devil false hope. "I'm not a high devil, I'm an Overlord demon." she said then immediately resumed her brutal beatdown not caring if the devil leader even knows what a demon, or overlord is.

"AHHHHHHHH"

"Hey your right torture is fun, scream louder for me, your screams of pain are much better than your terrible evil laugh."

The up and down motion of the folding chair continued until the devil leader is nothing but a pile of bloody mush on the ground.

"Wow, that was fun if not really messy." The girl said to herself as she put away the chair in an dimensional pocket, then summoning wind and water to rid her clothes of blood and bits, followed with fire to dry out her clothes.

It's been about a year since I reincarnated into the dxd world as a Disgaea Overlord. The girl thought to herself then letting out an audible sigh. This reincarnation is not without its problems however as she clearly recalls being an adult man in her previous life and now, she has to deal with a tiny demon girl's body, obviously that news was unpleasant to say the least, to cope with her new changes she came up with the solution, that if she can't put a dick in people to fuck them, then she will be a dick to fuck people over, especially all her favorite characters, like how a mischievous demon from Disgaea should act. Unfortunately, that plan has hit a wall too as she was reborn in the time of the war between the Devils the Angels and the Fallen Angels, a time where the big G is still running around, it will take at least 1000 years before she gets to even meet all the dxd character she knows. So, in the end she has to settle for messing with the different factions for now.

"Sigh" she let out an audible sigh again turning her head to the angel lying in the dirt, though recently it's been getting boring having the laughs all to herself, if only she can share her sense of humor, like in her previous life with friends and family.

"Wait, you there." She exclaimed excitedly noticing and pointing towards the angel on the ground. "I saved your life, now laughed at the peon's demise with me." She demanded.

Seeing no reaction, she walked towards the angel putting on hand on her to check on her condition.

"Curses, she's bled out, who will laugh with me now?" Just as she was about to leave, she notices a faint presence with the angel.

"Her soul, what luck!" She said with her eyes glowing in excitement. "I have a new goal now." She declared holding onto Amriel's soul. "With my power and authority as a Demon Overlord. I Jezabel now grant this soul new life as a demon! Be reborn as the first of the succubus race."

The soul glowed brightly as a body was formed around it encasing the soul, taking a shape similar to what the angel used to look like, except her body is now seemly more developed than ever before, her previously decently sized breasts is now even bigger along with her butt, her once pure and graceful body now resembles a body that is built for sin. Horns are seen attached to her head, just as a pair of black bat wings is present at her back replacing her previously pure white angel wings, a long tail is seen extending out her lower back with a heart shape tip at the end.

"I will just make new friends and family myself. As an Overlord I have more than enough power to create my own vassals." She declared ecstatically as she happily skipped towards the sensible devil lacky's body, while leaving the newly revived unconscious succubus lying on the ground. "And who know maybe even create my own netherworld and introduce this world to the bs power level of Disgaea, while fucking with everyone." she said to herself as she reached out towards the lackey's soul creating her second companion in this world.

This is how the origin of the demon race, the 4thmajor faction of the biblical cosmology began in the world of dxd.
