A collaboration between myself and Code-Emperor07, the author of many fantastic words, such as Fractured Existence and Tokyo Ghoul: The One-Eyed Swordsman, yada yada yada... Might be rude, but I am not one for foreplay.

So, let's get down to business. This is a crossover between DxD and Devil Survivor 2: Record Breaker. Originally, I was going to have three characters from the latter appear as guest stars with major roles, but after a debate, this seemed like a better option.

With that in mind... LET'S GET R' DONE!

Issei wheezed, feeling sulfer and ash breath into his lungs when he tried to gasp for air, his body lying face down on the ground. Pain was echoing every throughout his body, his school uniform tattered and worn out. His messy brown hair coated by smoke and ash, like the rest of him. Blood was leaking from the corner of his lips, dribbling down to his chin. His vision was blurry, hardly able to make out anything. He could feel the cold feeling of concrete beneath him, and the overwhelming heat of flames lapping all around him.

"G-guys..." he croaked out, lifting his head. When his vision was finally repaired, they widened to the size of dinner plates. Horror and shock flowed all around him.

Kuoh was reduced to smoldering rubble. Flames were devouring everything in sight, the corpses of fallen Devils, Angels, Fallens, and even humans. Nothing was spared. The entire city was reduced to piles of rubble, buildings slanted and on the verge of collapse. Smoke piled high into the air, forming black pillars. The sky had been tinged a fiery red orange, likely the result of the sea of flames that surrounded him from all sides.

However, this was not horrified him.

It was the sight of all of his friends and comrades, their corpses all around him and scattered.

All of them were dead in pools of their own blood. Some were lucky to remain in one piece, with only lethal wounds inflicted. Others...weren't as fortunate as they were mangled, torn apart, or mostly reduced to ashes.

Yuuto Kiba. His legs were torn away from his body, both of his arms broken, and a gaping, bloody hole where his lungs would be.

Saji Genshiro. Both of his arms were gone. His torso was completely twisted around. His head was bashed in by a fallen piece of rubble.

Irina Shidou. Half of her body was burned to ash, and the other half, crushed beneath the weight of debris.

Sona Sitra. Her right arm was gone, her glasses cracked, and a look of despair written across her face. No life gleamed in her once brilliant eyes.

Azazel. His wings had been all but torn, his jaw torn off, and one of his eyes skewered.

Xenovia. Her body was bisected diagonally. Her lower half lying a ways off from the other. Her intestines and innards were spread out from behind her. Her once, lively golden eyes were now lifeless. Her remaining arm was mangled beyond repair, looking more like a crumpled straw wrapper. Durandal laid shattered next to her. Some of its shards impaling her body.

Asia. Issei had no choice but to look away. The former nun's body was skewered and pinned to the far wall through metal poles that took flight from the explosion. Her arms, legs, chest, neck, and head were pierced through.

Akeno. Her body was one of the lucky few to be untouched, but horrible burns scarred her clothes. Her face was eeriely calm.

Gasper. He was being cradled by Akeno during their last moments. His eyes were scarred and torn, being nothing but scorched eyelids.

Cao Cao. He was run through by his own spear, impaled through the skull.

Jeanne. Her body was cut up, and a blade impaled through her heart.

Koneko. Her hands were scorched, and a giant hole was where her heart should have been.

Sairaorg. His hands were gone, leaving bloody stumps. His body looked...broken. As if she withstood something for as long as he could before giving in. Lacerations were everywhere. Some of his bones were sticking out of his flesh. His eyes were calm yet lifeless, his expression remaining resolute.

Sirzechs. Like his station demanded of him, he stood tall and proud, even in death. He was on his knees, his body battered and torn apart. His red hair matched perfectly with the blood that flowed down his face.

Serafall. She was one of the unlucky ones, her body completely skewed. Were it not for the wand that laid beside her, along with the remnants of what used to be her clothes, it would be impossible to recognize the mangled mesh that was once one of the Great Satans.

Grayfia. The Queen of the Crimson Satan. Her body too, remained in one piece. But her skin, like Akeno, was scorched. Her chest was ripped wide open. was kneeling next to her husband. Tears of blood flowing from her face...or what's left of it.

Arthur. His right arm and left leg were blown apart. His own sword was stabbed into his back, severing his spine. His glasses lay next to him, the frame bent out of shape and the lenses shattered.

The sight that horrified Issei most of all, however... was Rias Gremory.

Her body was completely blown apart. Her skin was torn open, blood leaking everywhere. Her face was expressionless, her eyes cold and lifeless, and her limbs sprawled across the ground. Several dozen spears had impaled her body without end, leaving her pined to the ground. One of her arms was stretched out towards him.

He felt tears pricking at his face. "No... Oh, God, please... no..."

Despite the pain he was in, he crawled forward, looking around. "S-someone... Anyone..."

There was no answer.

"H-help... Anyone..."

Still, no answer.

"S-someone... Please..."

The only answer he was receiving was silence.

Finally, Issei stopped, his body near his master's. He forced himself to look down at the ground, down at where Boosted Gear rested, it's crimson armor cracked, and the jewel shattered. "D-Ddraig..."

The voice of the Crimson Emperor had fallen silent.

"N-no..." Tears finally spilled. He had lost everything. His friends. His family. His teachers. His allies. His partner.

His lover.

He would never see them again. He was all alone. Alone in this Hell on Earth.

"Issei."

The teen looked up through a tear-stained set of eyes. Vali was standing in front of him, no worse for wear. He was clutching his right arm, which looked broken and shattered. The skin was a sickening purle, swollen at the hand with several deep cuts. Blood was dripping down from the palm. One of his eyes was also cut, a scar writhing across the flesh.

"V-Vali..." Issei whimpered.

The Vanishing Dragon's vessel's face was wrought with apprehension. Though he looked calm, he could tell he was sickened and horrified. "It seems... you and I are the only ones who made it."

Issei sobbed as he tried to stand, but ended up falling on his back. He coughed violently, feeling blood rushing down his face. He felt something warm on his stomach. He looked down.

There was a gaping hole in his stomach.

"There's..." he gasped out. "There's so much blood..."

The crimson liquid of life was pooling out from under him at a terrifying rate. His skin grew paler by the second. "...He...hehe...This much...is pretty bad...right...? Guh!"

"Don't try to speak." Vali knelt beside his rival. "Save your strength."

"...Hey...Vali...?" Issei choked out. "...This world...has gone through...so much crap...huh?"

Vali visibly grimaced, his hands becoming clenched. "Was it..." the dying Devil said with a tone of sadness and broken spirit. "Was it... because we... we weren't..." He coughed up more blood.

"Issei..."

"H-hey..." Issei tried to grin. "I-I'm glad... You're alive... Sure... Y-you were an ass... when we first... met... B-but... You... were awesome..." He chuckled, his eyes beginning to grow heavy. "Look after... This world... I-I know... You... can..."

He stopped breathing. His brown eyes remained open, so vibrant... yet crushed.

"...I know..." Vali closed his eyes in respect. With his single, usable arm, he brushed his fingers over Issei's eyelids, closing them. "...I shall continue where we left off...my rival..." With that, he stood up and began to walk.

However, he did not make it far. As soon as he made past two blocks, he fell onto his knees.

"Che..." the descendent of Lucifer growled, gasping for air when he felt his body start to go numb. "So... Even I wasn't spared from you... Arcturus..."

He was beginning to feel the darknes trying to take a hold of him, as if beckoning him to his embrace. He tightened his grip on his arm, forcing pain to keep him awake. "No... I... I cannot... Die here...!" he growled out, forcing himself to stand. "I must... protect... this world...!"

"I am afraid that in your current state, Vali Lucifer..." a solemn voice spoke out. "That is impossible."

Snapping his head upward, he found himself staring at a familiar figure. "You..."

The figure was a young man, approximately the same age as Vali. He had messy snow white hair and eyelashes. His cold blue eyes possessed a solemn glow. He was wearing a red and black stripped long sleeve shirt, black pants, and black shoes. He was gently floating down in front of the descendant of Lucifer.

"...Alcor."

The being held a sad, sardonic smile. "Such a cruel fate, isn't it?" he asked Vali. "This world had been deemed unnecessary... yet you all opposed it." The smile vanished when he spoke the next choice of words. "Even if you continue to live... this world no longer has a future. Arcturus has seen to that."

Vali didn't respond at first, struggling just to stay on his feet. "Vali Lucifer..." Alcor spoke to the half-Devil. "Do you want it all to end here?"

"Don't ask such stupid questions..." Vali spat. "Especially when you already know the answer!"

The smile returned as he offered his hand to him. "Then I think you know the best course of action."

Vali smirked as he took the being's hand. Slowly, a blue light engulfed their beings, and descended upwards into the heavens.

Neither of them had noticed the faint glowing green light within the jewel of Boosted Gear.

Highschool DxD: Shatter Destiny

"Time to wake up!" a loud, seductive voice rang in his ears. "Time to wake up! If you don't I might have to resort to more... 'extreme measures'!"

Issei Hyoudou groaned as he lifted himself up from his bed, slamming his hand down on the clock. "Ugh... What the hell..." he muttered groggily, his mind cloudy with a weary sense of drowsiness. "Why did I set my alarm clock up like that..."

At this moment, Issei paused. Alarm clock? He slowly shifted his now alert gaze to the contraption. Indeed, it was his old 'Onee-san' Alarm clock. What was it doing here? More importantly...how was he alive?

Wait... alive... what did that mean? Wait, how was he even in his room? Wasn't he out on the streets, dying after his battle with Arcturus?

Arcturus... what...?

'I... Is...ei...'

"H-huh?" the teen blinked, throwing himself upright and looking around the room. "Wh-who's that?"

'Iss...i...Issei...'

'ISSEI!'

In alarm, he snapped his head towards the source of the shout: his left arm.

His left...arm...Then his eyes widened his realization.

"D-Ddraig?!" He shouted out in surprise and utter joy.

'Phew, finally!' the dragon exclaimed. 'Seriously, Issei, what the hell were you doing? Actually... Wait, how are we even alive?'

"Alive?" Issei frowned. Then he recalled everything. How everything had started, how he and everyone banded together...

How they had all perished.

"Wait..." Horror settled over him. "D-Ddraig... Did we...?"

'...Yeah, we did, partner.' the Crimson Emperor answered gravely. 'Although, I don't remember what happened after Arcturus...'

"...Arcturus..." Issei spoke the name in distaste. He was utterly useless in that fight. He couldn't save any of them.

'Partner. It's not your fault.' Ddragi voice, reading his thoughts. 'The Administrator of the Triangulum was exceedingly more powerful than Denebola or Spica.'

"Dammit... I know that, but..." Issei growled, his hands clenching together tightly. That was when something dawned on him... something important. "Wait, why are we back at my house? And how are we alive?"

'Why are you asking me?' Ddraig snorted. 'You think I... What the?'

"Ddraig? What's up?"

'Issei... can you bring out your wings?'

The boy frowned, but nodded. He tried to bring out his demonic wings.

Tried, being the key word.

"Wait, w-what the?!"

No matter how hard he tried, he couldn't spread his wings. It was as if he no longer had them. "Wh-what's going on?! Why can't I unfurl my wings?!"

'I was afraid of that. It's because you no longer have them, partner.'

"B-but why?!"

'Well... It's because you don't have your Evil Piece, partner.'

"W-what?"

'Issei... you're not a Devil anymore.'

"...Say WHAT?!" He shouted in alarm. He was no longer a Devil? What happened?! DId he lose his Evil Pieces?

'Yeowch!' the dragon cringed. 'Hey, watch it!'

"B-b-b-but how?!" Issei panicked, unable to believe this. "W-why am I back to being human?!"

'It ain't just that, partner.' Ddraig informed him. 'The Crimson Cardinal Promotion, the Dragon Slaying Sword Avalon... All the power you gained through all the shit you went through, all except for Juggernaut Drive... It's gone.'

"WHAT?! How is that possible? All the hard we work we did to get them...just poof?!"

"I'm just as confused as you are. It's as if time has been regressed!"

That caused the Devil-er, human, to pause. Time... regressed...?

He looked at the calender hung up on his wall, revealing an ecchi seen with two women in a rather erotic pose, enough to give a man a raging hard on.

The date was...

"No. Way..."

'Well, I'll be damned.'

It was six months. six months before Rias Gremory reincarnated gim into her pawn.

"I..." Issei was at a loss for words. He just continued to stare at the calender in complete and utter shock. "H-how..."

'Well, this explains why everything except for Juggernaut Drive is gone.' Ddraig remarked. 'We're back in the past.'

"But... how is that...?" he started out, but then a thought came to him. "Wait... could it have been Vali?!"

"Issei!" the familiar voice of his mother called out. "Are you up?! It's time for school!"

It was the voice he thought he'd never hear again. Just the sound of it brought tears to his eyes.

"Y-yeah! I'm getting up!"

Issei quickly removed himself from bed, tossing off his nightly clothes. During this time, he resumed his conversation with Ddraig.

"Do you think Vali found a way to reverse time?" he asked, removing his shirt and tossing it to the floor.

'Who knows?' the dragon snorted. 'Of course, that being in the stripes could have also had a hand in this as well.'

"You mean that Anguished One guy or whatever the hell he calls himself?"

'Indeed. As far as I can tell, he is not human. Neither is he Angel, Fallen Angel, or Devil. He is something else entirely.'

"Is he a Triangulum, do you think?" Issei pondered. Ddraig had to pause for a moment.

The idea itself would make sense. The Anguished One had a vast amount of knowledge, more so than what anyone would think possible. He was not human, for his mastery over the magic arts were beyond the realm of normal humans. However, he held neither the angelic grace nor the demonic taint that the Great Factions possessed.

However, there was one difference between him and the beings that wanted to bring the world to an end. 'No, it's not possible.' the Crimson Emperor decided. 'The Triangulum exist to destroy this world... the Anguished One gave us information of how to combat them. Why would the enemy give us info on his own allies?'

"Huh...I guess that makes sense." Issei nodded. But if he's not a Triangulum, then what is he?

'Still, his presence is similar to the Triangulum. It's possible he could be related to them in some way.' Ddraig advised. 'We may run into him again.'

"Yeah." his partner nodded in agreement before frowning. "Hey, Ddraig... do you think everyone might remember what happened?"

'I don't know, Issei...' the Crimson Emperor answered. 'I just don't know...'

Issei felt silent after that, deciding to focus on the life he had at this time for now, making his way downstairs.

I remember when they first appeared... It was so sudden, right out of the blue. We were still dealing with the chaos the Khaos Brigade created when the world suddenly became the very definition of Hell.

These...beings suddenly appeared from the sky. Each time they spoke, or at least thats what I thought they were doing, all we heard was cybernetic humming and gibberish. They weren't even trying to communicate...they were trying to destroy us all.

We didn't know how it happened, or why they appeared... all we knew was that they wanted nothing more than to see all of us wiped out.

Humans.

Angels.

Fallen Angels

Devils.

They wanted to wipe out every being in existence, and bring this world to ruin... It was almost like we had just been thrown headfirst straight into the apocalypse.

We were frightened, confused... horrified by the damage they brought. Several millions died in a span of only three days... and in those three days, the world had reached an end.

I still remember our meeting with the one called the Anguished One... the man that told us who these enemies were, and what they wanted.

They were called the Triangulum... and their sole purpose for existing was the complete eradication of the world.

It was on that day that we knew... this life we all led... whatever peaceful times we would have had ahead of us... they would never happen.

All we could do was survive, but... in the end... we had failed.

The Triangulum had won. Vali... what did you do? And why did you bring me back to the past? Before I became Rias' pawn?

Where could you be...?

...right, I wasn't really expecting an answer. But seriously, jut what happened after I died? I thought the world was consumed by the void. So why is everything regressed to several months before e invasion?

Well, whatever the case is, I have the opportunity to clear things up.

Although...

...

...

...

...How am I supposed to get Buchou and the girls to like me again?
