AN: I don't own DC/Young Justice, DMC/DmC, or Highschool DxD

If I did, Jason would get more love and screen time, Devil May Cry would would have an awesome open-world game with an explorable DMC building as a home base, and Highschool DxD would have a new season already.

Chapter Eight: "Holy Hell Meetings, Batman"

It's been a week since the Jason fought Vergil and they had defeated Mundus.

Limbo City is going through repairs while the military and heroes were fighting Demons all over the globe.

Jason himself helped where he could, with a paycheck as a bonus. Kat was also helping the city via food distributes and the information network. They had taken an abandoned building in the red light district as a base.

Jason enters into the building where Kat was sitting at an old desk near the door.

"Hey Kat, I'm back", Jason waves to her.

Kat looks to him, "Hey, Dante. Welcome back", she waves back to him before getting up from her seat, "People were asking about you again".

"Oh, really? Who?", Jason asks as he sits down with a box of pizza, thankfully for Jason, one of the few restaurants still intact from the battle.

"People blaming you for demons running amok, people wanting to thank you for freeing them from demonic influence, heroes wanting to investigate you, same with the government", Kat lists off as she comes over and takes a slice.

Jason takes his own and says, "Yeah, well, I hate most of that kind of attention", he takes a bite, "Sorry for leaving you to the wolves".

Kat waves it off, "It's fine. Just happy to be able to walk the streets without being called a criminal".

With the reveal of demons, the likes of Bob Barbas and Kyle Ryder were also outed as being on the side of demons, putting all they have said and done into question. Other officials were on trial for their dealings with the men in question, such as the president.

Thus, Jason and Kat along with the Order were free of persecution. Jason had also used his own hacking skills to erase their identities from the media and internet so they could live mostly normal lives without drawing attention.

The Order remnants have moved on and were forming a Demon Hunting Guild under the UN, with Jason and Kat labeled as free agents as t not draw more attention to them.

Jason was just waiting for a certain foot to drop on him.

Ding-Dong, the doorbell rings to the building they were in.

"That thing still works?", Jason asks himself before carefully heading for the door with Ivory in hand just in case.

He opens the door to reveal a handsome looking man with an almost womanly face and long blond hair with green eyes. He wears a red robe with a gold cross on the front of his white alb. He also has golden shoulder plates with a white sash from them.

Their was also an extremely beautiful woman with curly blonde hair and a voluptuous figure. She wore a white nun habit/dress with gold accents. A silver circlet across her forehead and a blue flower from her left ear.

Most notably, both had halos over their heads and 12 wings each behind their backs. The guys were golden in color.

"Greetings, Dante, Son of Sparda", the man says to Jason.

"And who the hell are you?", Jason asks with a quirked eyebrow.

"My name is Michael, a Seraph of Heaven", he introduces himself.

"And I'm Gabriel, a fellow seraph of Heaven", the woman introduces.

'I thought Gabriel was a guy?', Jason thought before looking around for any witnesses before saying, "Just get in here before people start staring", holstering Ivory away and letting them inside.

The two enter passed Jason and he shuts the door behind them. They seem to dematerialize their wings into their bodies, but leave their halos exposed.

Kat was stunned, "D-D-Dante! Are those A-A-Angels?!", she stutters out.

"Looks like it", Jason tells her as he heads back to his seat and grabs his pizza again, kicking his feet up onto the table, "So, where you at when we were fighting Mundus?", freaking Kat out a little.

"We apologize for our negligence in the battle", Michael began, "Due to past attempts, we left it to prophecy that a Nephalem would be his defeaters. And for the last thousands of years, we were focused on just containing him to this continent and city since we thought all Nephalem were extinct".

"Hmm", Jason sighs as he then continues to eat his pizza, "So, why are you here now?", he asks them.

"Well-", Michael goes but his cut off.

Ding-Dong, causing all four to look to the door.

"More guests, I guess", Jason sighs, this time bringing out Ebony as he heads for the door.

He opens it to reveal two more people, also a man and a woman.

The guy is a handsome man who seems to be in his early 20's. He has shoulder length crimson hair that his longer bangs by his ears and blue eyes. He wore a fancy rich man suit, like from a fantasy story or something.

The woman is a beautiful girl; looking in her late teens with black hair, tied into twin tails and blue eyes. She also has a child-like body (albeit with large breasts). If Jason had to guess, her body measurements are B85-W56-H80 cm; height is 5'2.99" (160 cm) and body weight is 105.8 lbs (48 kg). She wore a japanese magic girl outfit that was pink in color.

"Greetings, Son of Sparda", the redhead goes.

"Yeah, yeah, come in", Jason waves him in and the duo do so.

"I am Sirzechs Lucifer and this is Serafall Leviathan, we are two of the Four Great Satans", the redhead introduces them.

Jason leans over to Kat, "Four Great Satans?", he asks.

"During the final battles of the Great War, the four leaders of devil kind were killed. Four new and powerful devils were chosen to lead in their place since then, the original fours' names now being titles", Kat whispers back to him, "These are the current holders of the Lucifer and Leviathan titles".

"We thank you for defeating Mundus in our stead", Sirzechs says with a bow of gratitude.

"Yeah, thanks for beating that big meanie", Serafall cheers cutely with a raised fist.

"Right", Jason sighs in exhauserbation as he takes another bite of his pizza.

"Sirzechs", Michael greets.

"Michael", Sirzechs greets back.

"Serafall", Gabriel greets warmly with a smile.

"Gabriel", Serafall greets coolly with a scowl.

"Nice to see angels and devils on friendly terms, I guess", Kat remarks.

Ding-Dong*

"Ugh, door's open, just come in already", Jason calls out to the door, annoyed.

The door opens and in steps a middle-aged man.

He is a tall man with an average build, black hair, golden bangs, and black goatee. He wore dark slacks and brown dress shoes with a V-neck maroon long-coat with a wide, open high-collar that opens up at the hem. The long-coat also featured two black belts around the waist and four black bands on each arm, two of the bands at the wrist and the other two near the elbow.

"Hey, everybody", he greets Jason and everyone else.

"And who are you?", Jason flippantly asks, tired of all the guests just showing up to his place

"I'm Azazel, Leader of the Fallen, the last faction of the Three Factions", he introduces himself.

Jason leans over to Kat again, "Three Factions?".

"The main three fighting forces from the Great War, sans Demons, and they all fall under the One God pantheon", Kat informs.

"Demons were far too beastly to be considered a Faction", Azazel remarks, "Too few intelligent members, not even capable of thinking, let alone talking".

At that, Jason nods in agreement. Most demons were practically empty shells and beasts that looked like they were made on assembly lines from how similar they were. Very few have ever said anything or shown tactics when fighting him.

"The Nephalems were the original third faction", Michael reveals, "Before Mundus, anyway".

"And he's why your all here?", Jason asks as he eats another slice.

"Yes, his defeat has freed many souls and has led to a vacuum of power on Earth", Sirzechs informs.

"As the victor, you get his territory", Azazel adds on, "Basically, all of Limbo City other surrounding cities".

Jason goes wide-eyed in surprise, "Seriously?", pausing in his pizza eating.

"Yep", Azazel nods, "Though, it's only in the supernatural sense. Humans won't know about it".

"Oh. Well, that's good, I guess", Jason remarks, not wanting too much attention from certain parties.

Sirzechs steps forward, "We will help rebuild the city as thanks for defeating Mundus along with other compensation".

"All of us will join in", Michael adds on.

"I guess this will be the first time the Three Factions have worked together since the ceasefire", Azazel remarks with a goofy smile.

Jason glances between the five powerful beings before looking to a fidgety Kat.

"Alright", Jason decides, "We could use the help, I guess".

"Alright then, I know a construction company that will rebuild the city", Sirzechs shares.

"Sounds good", Jason comments as he takes another bite.

Gabriel steps forward, "By the way, may we see your wings?".

"Huh? My wings?", Jason aks in confusion

"You know...", Gabriel goes before unfurling her twelve white feathered wings.

Michael unleashed his own 12 golden feathered wings, and Azazel showed his 12 jet-black feathered wings, while Sirzechs and Serafall only unveil a pair of wimpy looking bat-wings from the small of their backs.

"Oh", Kat looks on in awe.

Jason squints his eyes and points at them, "Um, I've never done that before, so how am I...?"

"Just... focus your energy to your back", Sirzechs tells him.

Jason does so and a red angelic feather wing sprouts from his rights shoulder blade area, similar to his Angel trigger wings but more realistic instead of astral, while nothing sprouted out from the other side.

"Only one wing?", Azazels asks aloud in confusion. With his victory over Mundus, the Angels and Fallen Angel assumed he would have multiple angel wings, not just one. And they all were confused on the lack of a devil wing.

"That's weird", Serafall agrees.

"Alright, alright. Enough gawking", Jason tells them as his wing vanishes behind him.

"Ah, right", Azazel coughs before looking to Jason, "By the way, I'm something f a scientist that studies unique treasures and... gear, and I was wondering if I could get a look at your Arms.

"My Devil Arms and Angel Arms?", Jason asks him, drawing a raised brow from most in the building.

"Oh-ho-ho yes", Azazel smiles like a giddy kid in a candy shop.

"Well...", Jason goes before summoning Rebellion to his back and drawing it before placing it blade pointed to ground before him, "This is Rebellion... given to be by my father".

"So this is one of the former swords of the Dark Knight Sparda", Azazel remarks in awe while leaning in close. with the other members of the Three Factions. With Azazel noting that pommel was closed into a diamond, the guard arms were against the ribcage and the skull mouths were closed.

"You might want to back up for the next part", jason tells him before resheathing Rebellion and changing to Arbiter, "this is Arbiter, made from the left over soul of my father from our home within a portrait", as it laid on its blade head.

They could hear the floor creaking from the weight.

"So, Spard's soul created a battle axe", Sirzechs notes, finding the irony in a swordsman becoming an axe.

"And this one...", Jason goes as he switches out the axe for a scythe, "is Osiris, made from my mother's soul remnant".

"A scythe, like an angel of death but pure white", Michael remarks, while Gabriel was drawn to it like a long lost sister, "How she never became a Fallen is still a mystery that will now go unsolved".

"From your mother, you said? That would explain why you call it an Angel Arm", Azazel says in thought.

"Yeah", Jason says in agreement, "Next is...", before switching it out with a handle of swirls, "The Ophion".

"Uh... a handle?", the others in the room were unimpressed, sans Kat who already knew.

"Heh", Jason smiles before channeling his angel side into it and it changes to a white chain serpent before then channeling his devil side and it changed to a red four-pronged hook, "It's actually a grapple hook, white for pulling me towards something, red for pulling something to me".

"Oh, now that is much better", Azazel remarks with a smile, "So how did you get his one?".

"I... don't really know", Jason answers, not really sure on how to answer that. And he didn't want to talk about that mental world, nor will he mention that it might be his only Nephilim Arm.

Jason sheathes it, "Anyway...", and he the bag ass gauntlets then cover his hands, "this is Eryx, from the Succubus behind Virility".

"Succubus, huh?", Azazel smiles lewdly.

"She was ugly as shit, like a slug-cockroach", Jason remarks, wiping away Azazel's smile.

The gauntlets are then switched out for the tri-blade shurikens, "These are Aquila, got them from Bob Barbas. Though, I don't know why he's an Angel Arm".

Azazel brings his hand to his chin in thought before saying, "Maybe because he was actually a Fallen that sided with Mundus instead of being under my banner".

"He was a Fallen?", Jason asks in confusion.

"Born a fallen and hit every branch on the way down away from his parents good genetics", Azazel remarks.

"Hehe", Jason chuckles at that, "And I think that's it".

"Not even your guns?", Michael asks him, remembering seeing them when he approached the door for the devils.

"I wasn't sure any of them would be considered Arms", Jason remarks in thought.

"Maybe, maybe not", Azazel shrugs.

Jason sighs as he puts his Arms away, "Anyway, if we're all done here, can ya leave so I can eat my pizza in peace before I have to scrounge around for desert?"

Michael, Gabriel, Sirzechs, and Serafall all bow in respect while Azazel does a wave as he leaves out the door and soon were the others gone, leaving just Jason and Kat again.

"Now that was a pain", Jason remarks before grabbing another slice of pizza.

A Month Later

Jason had to hand it to Sirzechs as that construction company he knew about had completely rebuilt the city within a month. Like, they had the Flash Family on their payroll or something.

Another thing Jason found out about this last month was the Three Factions erasing memories of demons from the overarching human kind, along with knowledge of The Order and all those involved in it.

Humans that already knew of demons and other supernatural beings or suspected their existence were spared, such as former Order members and superheroes, so the Hunter Guild was still active and Jason was still in business with them.

This led to a new problem as the Justice League and the Team were investigating Limbo City as to why the world has forgotten about demons running rampant.

Jason wanted to avoid meeting with them again. Who'd want to have to explain coming back to life and being some celestial being instead of a human like they thought.

But he knows he's going to have to deal with it eventually, so might as well go and meet with them now.

He was on a rooftop with his hood up over his head, looking to the night sky for a familiar pointy eared caped crusader.

Jason was able to spot him around midnight, leaving a conversation with Wonder Woman via his holographic computer on his gauntlet. The Batman glides down from his previous rooftop and lands near his location, so Jason reveals himself.

"Hello, Dark Knight of Gotham", Jason says, his voice imbued with demonic and angelic energy to sound otherworldly.

The sound of said voice actually startles Batman and he turns in the direction of it with a Batarang drawn to see a black and red hooded figure step out from the shadows.

"Who are you?!", Batman demands, his Batarang still at the ready.

"I am Nephalem, a hybrid of Angel and Devil, and, technically, the reason behind all this", Jason replies.

"What do you mean?", Batman asks with narrowed brows behind his cowl.

"There exists a Demon King known as Mundus, who ruled the corrupted souls of the world with his demon subjects. Powerful beyond measure and immortal to all harm", Jason explains as he walks around Batman, "There spoke a legend that he could only be defeated by a potentially powerful race known as Nephalem, like myself. When he learned of this, he wiped out the species while they were young and remained powerful for years till he was betrayed by his blood brother, The Dark Knight Sparda".

"Dark Knight?", Batman asks in confusion.

"You share an epithet, but he wielded it far longer and is known in much more powerful circles", Jason informs, "He is a devil that saw the humans under Mundus' rule and awoken to justice, betraying Mundus and sealing him away in hell. Many centuries later, he met an angel and fell in love. She was unlike any other angel as she would not become a fallen while she wed a devil. Through them, true born Nephalem returned to the world, and Mundus awoken in anger".

Batman puts away his batarang and relaxes a bit as Jason continues, "He discovered a way to act on earth through a realm called Limbo. Using it, he took possession of a body, known as Kyle Ryder. He tracked the couple down and killed them, Sparda having lost his power and Eva not being a fighter. Their son was on the run and lost his memory of his life before, believing himself human for years, almost a decade, till just over a month ago where I destroyed Mundus' hold on humanity that he had grown for the past decade and severed his ties to Earth", stopping before Batman, "The Angels decided to change the memories for the innocents for their safety", altering that pat as he wasn't sure it was just the Angel Faction that did it.

"That's quite a story you've told", Batman remarks, "But why should I believe a word of it? Why should I trust you?"

Jason knew that would be asked and knew what was coming before he lowered his hood and spoke with his normal voice, "Do I have a reason to lie to you, Bruce?"

"Jason?", Batman asks in disbelief and wide-eyed.

"Yeah, it's me", Jason sighs.

"B-But how are you here?", he asks his young ward / adopted son.

"Dip in Ra's al Ghul's favorite jacuzzi at Talia's hands", Jason answers, "Immediately ran for it and ended up knee deep in demon shit".

Batman wastes no more time and hugs the second Robin, which Jason returns in comfort. After a moment, they broke apart.

"Why? Why didn't you come back to Gotham?", Batman asks him.

"You had a new Robin", Jason answers, "I saw no point in staying and went to strike out on my own like Dick did... but ended up fighting demons rather than crime".

Batman remained silent for a moment at the thought of replacing Jason before saying, "Robin... wasn't my idea. I didn't want to work with someone underage ever again, but I was getting deranged in my crime fighting, Dick and Tim acted on their own to help me recover and be a better hero".

Jason could assume Tim was the Robin that replaced him and nods, "Well, I probably should have stopped by to check on Alfred".

Batman looks to him, "You could see him tonight, He'd be so happy to see you".

"Maybe some other time, I'm needed here in Limbo City right now", Jason denies, "I was just stopping you to inform you and indirectly the League and Team of what happened and get back to your previous engagements", before then mentioning, "Also, try not to mention me coming back yet, I don't want to deal with any emotional visits, especially from those I don't even know".

Batman nods in agreement, "Right, I'll have everyone meet on the watchtower and inform them of what has happened", he smiles to Jason, "It's... good to see you again".

"You too, Bats", Jason returns the gesture, before Batman grapples away with plans to leave the city.

The Next Day

It was midday after Jason met with his old mentor and Jason was resting from another job while Kat was out on business with the Hunter Guild.

Suddenly, a red glyph circle appears before his desk he was lounging at. A figure rises to reveal Sirzechs Lucifer, who was greeted by a gun aimed at his face.

"You seriously need to announce yourself", Jason remarks at his surprise visit before holstering his gun.

Sirechs sweats, "Sorry, but I was in a hurry to meet with you".

"And why did you want to meet with me?", Jason asks him.

"You may not know this, but I have a younger sister", Sirzechs tells him.

"And?", Jason asks dismissively.

"She has been going to school in a neighboring town on the outskirts of Limbo City, Kouh Town. A township dedicated to japanese culture, which my sister loves", Sirzechs informs, "It's technically been a part of Mundus' territory till now and I've been worried about stronger enemies going after her".

"Let me guess, you want me to keep an eye on her?", Jason asks him.

"Yes", Sirzechs agrees, "Who better to protect her in my stead?".

Jason sighs, wiping his face in annoyance before saying, "Well, I might as well finish my schooling. Where does she go to school then?"

"Kuoh Academy", Sirzechs answers, "It was once an all female school before going coed in her second high school year. She will be in her final high school year there, like you will be, will it having several divisions of schooling, including college. It also follows japanese school years in that it starts at the beginning of April and ends next year in March".

"So I need to get in right now?", Jason asks him.

"Yeah. I can handle your transfer in", Sirzechs tells him.

Just then, Kat walks in.

"Hey, Dante", she greets before seeing Sirzechs, "Oh, Lord Lucifer".

"Just call me Sirzechs, Kat", he asks of her.

"Hey, Kat, have you finished her schooling?", Jason asks her.

"Uh, I got a GED", Kat answers, unsure on how to proceed with that.

"Guess I'm the only one that's going to school with the devil's sister", Jason remarks.

"What?", Kat asks in confusion.

"Sirzechs here has hired me to watch his sister at Kuoh Academy", Jason informs her.

"I never said...", Sirzech goes.

"I'm not doing it at of the goodness of my heart", Jason cuts in.

"Alright...", Sirzechs hesitantly says.

"So, since you won't be going with me to school, can you act like a secretary for me with the Hunter Guild?", Jason asks her.

"I guess", Kat tells him, "But what are you going to do for transportation for school, unless you plan to stay there".

"Actually, he can teleport like we all do", Sirzechs informs them before looking to Jason, "How can show you how?"

Another Week Later

Jason was before Kuoh Academy in the uniform for boys. It was mostly black with white linework through out with a white short-sleeve pinstripe top under the jacket. The jacket and shirt were unbuttoned to reveal a red shirt. While most boys wore it button and zipped up with a black ribbon tie.

The girls' uniform consists of a white long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, a black shoulder cape and matching button-down corset, and a magenta skirt with a white underskirt beneath it.

"Well, lets go to class", Jason tells himself before heading to his classroom.

He made his way through the halls before his classroom and entered inside.

Jason first notices the only redhead that looked remarkably like Sirzechs if he was a younger female, wearing the school uniform for girls with an impressive bust size emphasized by the uniform's corset. She must be Rias Gremory, Sirzechs' sister.

He also notices a petite girl wearing glasses that looked similar to Serafall if she had short hair and violet eyes, with a slimmer build.

He could also feel the devil power they possessed along with others in the class.

"Oh, it's our new student", the teacher says, noticing Jason's in the room, "Come to the front and introduce yourself".

Jason walks to the front and smiles to the class, "Hello, my name is Dante..."

Chapter End

AN: basically some rehashing and introductions/meetings.

I used the Three Factions to reset the knowledge of Demons so most humans can still freak out when it's revealed in the DxD series, though those that already knew will mention the events previous.

Note: Jason does wear the uniform like Issei does and that's for a reason that you'll find out next chapter.
