Heaven

Next to Gadreel's prison, where after all these years he still resided, another cell was next to him. Except this one was massive in size, with seemingly impenetrable walls, and a closed door, making it completely dark on the inside.

Within that cell was a man. A man that had not spoken a single word in his whole time there. Nor had he seen a single ray of light or even moved an inch. He had been fed nothing either.

A gruesome scene was in that cell, a man chained to the stone wall, with multiple metal stakes covered in magic circles were penetrating parts of his body such as his head, arms, feet and legs.

The guards that were constantly outside the two prison cells froze as they heard a sound from within the room.

"Hmm~hmm~hmm~hmm." A hum softly rang throughout the hall.

"...Is that coming from him?" One of the Angels asked while gulping.

"Don't worry about it. There's no way he could possibly escape from all that. It's a miracle he's even alive." The other one said.

"R-Right." The two stood in silence for a moment before he spoke up again, eager to change the subject. "So, have you heard about what happened in Tartarus?"

"Yeah, apparently the Demons that were sealed up there escaped, and have allied themselves with some pretty strong people-"

"Hey!" The voice from within the cell yelled.

The two Angels had a look of pure terror on their faces as the voice continued.

"That's pretty interesting." The voice said with a mischievous tone.

The two Angels quickly jumped back as..

BANG!

The massive door that was guarding anyone from exiting or entering, had a huge dent of a foot imprinted from the inside, and fell over like a log.

"N-No way!" One of the Angels exclaimed.

Out walked a tall muscular man with scarlet eyes, pale skin and lightly colored wild hair that was spiked up. He was wearing red pants and shoes that had metal parts sewn into them, while leaving his upper body bare.

Some of the chains he was subdued with still were around him, along with gaping holes in certain part of his bodies from the metal stakes. However with the way he walked, it was as if he felt no pain.

The man yawned loudly as he stretched his arms. "Ohh, it sure is nice to get out for a walk every now and then~."

"You... how did you break out?!" One Angel said.

"Why now!?" The other one exclaimed.

"You can tell just by looking." The man said in a matter of fact tone.

RIP!

A sickening sound rippled through the hallway as he ripped out the last metal stake in his body, showing no signs of pain.

"I kicked the door down. It's because you guys were having such an interesting chat. So, Tenma is alive still?

As the Angels started to back up slowly, a voice echoed down the long hall.

"Hey! What's all the commotion here?"

A man in his twenties wearing a literal ninja outfit walked down to them. This was Metatron, one of the Seraphim.

"Metatron-sama!" One of the Angels shouted.

"Huh?" The man mumbled as he looked over to Metatron.

Metatron narrowed his eyes at the sight of the prisoner, and tensed up slightly. "Greed? I don't know how you broke out, but you'd better go back in."

"Eh? There wasn't any stupid ninja when I was imprisoned here all those years ago. Are you new? Listen here kid, that's no way to talk to a legend like me." Greed said as he put his hand under his chin.

Metatron stared at him. 'Not a very good situation at all. Of all the times for this to happen...'

He turned to the two Angels. "Report this to Michael-sama! One of our big prisoners escaped, so I had no choice but to kill him."

"Right!" The two said as the ran down the hallway with incredible speed.

Greed put his hands on his hips as if he was getting bored.

Before he could do anything, Metatron formed a kunai made of light and slashed the man from head to toe with a flash.

"Ahh~, that sure hit the spot. I don't think those would have healed if you didn't do that. You're pretty weak you know, ninja." Greed said as he stretched again.

"You dodged all those despite all the wounds on your body!?" Metatron exclaimed.

Greed grew a wicked smile as he turned around. "Wounds? What wounds?"

"...!" Metatron couldn't believe his eyes as the man looked completely healed, from head to toe.

Greed started looking over, as if he was unimpressed with himself.

"No way... you just had magic-enforced metal stakes ran through your body..."

In that moment of being scared, Greed had disappeared, and appeared in front of Metatron, and grabbed him by the throat.

Lifting him up, Greed tilted his head and grinned. "Those were some pretty flashy moves back there, I'm sure you won't mind me taking them right? After all, when you're dead it doesn't matter... huh?"

"N-No..." Metatron said, gasping for air.

"Eh? What was that? I couldn't quite..."

SNAP!

In that second, Greed crushed Metatron's throat with his hand. "...Hear you."

Metatron's body convulsed for a minute, before going limp, prompting Greed to drop him, and flail his hand around, to get the blood off.

"Oops, I didn't mean to kill you so quickly. I guess being trapped in a prison for over 4000 years can really make a guy pissed. Oh well, at least I got his magic~." Greed said as he nonchalantly threw his hands behind his head.

As he walked down the hall, he turned to the left and noticed Gadreel sitting in his prison silently. Then it struck him that this was the only other prisoner in here.

"Hey." Greed said.

No response.

"I said..."

CRASH!

Greed kicked down the metal bars that covered his cell.

"...HEY!"

Greed was a little thrown off by Gadreel's appearance. Rather than this, he expected some adult.

Gadreel was a young man with fair blonde hair and golden eyes. He was wearing a white jacket with a collar and scarf over a pair of black shirt and pants, along with a brown belt. Overall, he did not even have the face of a criminal, rather, he gave off a peaceful vibe much like Dulio.

"...Can I help you?" He asked in a light voice.

Greed was once again thrown off by this, but played it down as he grinned again.

"Wanna come with me?"

Gadreel stared at the ground for a minute, and slowly stood up.

"Lead the way."

Kuoh Academy, a few days later

"And why do I have to do this again?" Kaii asked while crossing his arms.

Currently, it was the evening and Kaii, Sona, Tsubaki, Rossweisse, Serafall and Sirzechs were gathered in the Student Council's room for an "examination".

"Because Sirzechs-sama wants to see what you can do when you access the power of the Heavenly Dragons that is now a part of your body." Rossweisse said.

"Yeah but why do I get a bad feeling about this..." Kaii said under his breath with a sarcastic smile.

Sirzechs, as if predicting something, said he had to go do something, as he stepped out of the room.

"Alright Kaii, you know what to do." Sona said.

Kaii closed his eyes and imagined his power flowing like a Dragon. Then he formed the mental image of a Heavenly Dragon, as his aura calmly surrounded him.

"And..." Kaii then exhaled and put his right hand forward. "...Flow!"

In that split second, Kaii realized what was about to happen, following a lecherous giggle from Okuma.

RIP!

Kaii managed to be awestruck, dumbfounded, and also embarassed at once, as his magic literally used Issei's signature Dress Break.

Rossweisse and Serafall went to cover themselves, but Kaii stopped looking when he noticed something.

Tsubaki and Sona's clothes weren't ripped.

"...Shit." Kaii noticed.

Tsubaki's hand was out, as her and Sona scurried out of the room.

{What happ-}

RIP!

Kaii's clothes also went away...

That's when Okuma remembered when Kaii fought Tsubaki in the tournament about 6 months ago.

Mirror Alice. The Sacred Gear that would reflect anything used on it back to the user.

Serafall wasn't nearly as shaken as Rossweisse, who was borderline on having a panic attack.

"Well..." Kaii started to say, as it finally kicked in he was not wearing anything. In his own panic, he tripped on his own foot and...

{This is so cliché that I can't help but love this!}

Of all times, Kaii stumbled right on Rossweisse.

"Huh?" Kaii asked with spinning eyes.

{Heaven is only a glance downwards.}

"What do you mean by..."

That was when he noticed his hands on Rossweisse's (very sizable) breasts. It also kicked in once again that they were both not wearing anything now.

"...Well at least they aren't small." Kaii muttered under his breath.

Rossweisse came to and started look up as her face progressively went through every red on the color wheel.

"U-Uh, stay calm and listen." Kaii started as he closed his eyes and made a shaky smile. "I'm sure in a few seconds from now, I'll be bleeding from all over my body."

Kaii at this point swallowed his pride and completed his shaky smile.

"So I'm going to say this while I can..."

Serafall may hay been childish, but even she knew this was a radioactive meltdown waiting to happen, so as she made an awkward face she made a new outfit appear around her from a magic circle, and closed her eyes.

Kaii spoke words that only the most brave of men could say. "This feels pretty incredible." By now his voice was serious whisper that was nervous and scared. "Thank you, and I'm sorry."

And then, the fuse hit its end.

"NO!" Rossweisse's scream echoed throughout the entire city.

If you were to ask some civilians, they would have sworn they heard a sickening splattering sound right afterward.

Rossweisse, now with a new outfit, stomped out of the room, leaving Kaii on the ground, with a horribly disfigured face.

{Boy, she has one hell of a temper.}

"Indeed Okuma, if only she was as enthusiastic about that kind of stuff as Akeno..." Kaii whispered in pain.

Kaii slowly got up and formed a new outfit from his magic circle, along with using his magic to mostly heal his face.

Serafall walked over to him slowly. "Are you okay Kaii-chan?"

Kaii's already damaged pride took another shot with that honorific. "I to- oh never mind. At least I can always count on you Serafall."

That was when his eyes widened. He looked over to her and she also had a surprised expression, along with a tint of red in her cheeks.

'Whoa, that's the first time I've ever called her that. Man what's getting into me recently?' He thought.

{And the glorious harem begins~!}

With perfect timing, Sirzechs appeared at the door. "Eh? Where did everyone go?"

Kaii just facepalmed.

About five minutes later, Serafall had decided to head back the Underworld (not before giving Kaii a goodbye kiss on the cheek), as Kaii and Sirzechs went to the Occult Research Club.

"What's that?" Kaii asked.

"It's a report that you need to help me fill out. The Zodiacs have requested a full report on what happened from your fight with Hades, until when their leader came. You can start when you're ready."

"Hmm, well it started when me and Vali came there. Vali used his new mode to defeat Pluto instantly. But since he's only used it a few times, the time in that form was barely a minute, so he collapsed after it. I was fighting Hades and-"

Sirzechs looked up at him with a suspicious face. "Not to interrupt, but I'm interested in what exactly you used to fight him."

"It was a doping that Diehauser got from an arrested Khaos Brigade member. Apparently it was made from the blood of the old Maou, and it activates something called Chaos Drive in a Sacred Gear. But using it more than once can alter the body of the user. In the end, it wasn't even worth it as Hades still was way stronger than me."

Sirzechs looked deep in thought. "Diehauser... huh... anyways, continue."

"After I got beat around by the damn bag of bones, that Demon, Hyskoa showed up. He pulled a trick on me and convinced me that Shinji was killed by Hades in front of my eyes. After that... it's kind of a blur. I remember beating the hell out of Hades... I was using a fraction of Order's power, who was apparently inside me all along."

"So that was Order's power? Along with those chains that are in Hades?"

Kaii shrugged as he looked outside. "I guess. After that, the eye patch Demon grabbed me and took me into Tartarus. In there is where I saw Rizevim, Euclid and those two Dragons."

"Euclid Lucifuge... not a name me or Grayfia ever thought we'd hear again. As the name implies he's Grayfia's brother. He was thought to have died in the civil war years ago. To think he's working with Rizevim now... what about the Dragons?" Sirzechs said with a hand over his head.

"Crom Cruach and Grendel. Okuma called them Evil Dragons, but apparently they shouldn't be alive anymore, so we're assuming that Demon Tyrant, with the ability to bring people back to life is behind them. From there you know the rest basically." Kaii said.

"Yeah, do you have any idea what that pillar of light was that went through the Underworld?" Sirzechs asked while finishing up the report.

"...No."

Sirzechs then got out of his seat and grabbed the paper. "Alright then, that's all we need. Thanks for helping me fill this out Kaii-kun. I've got to run this there, so I'll see you around."

Kaii bowed as he left.

He looked out the window, seeing the sunset in the distance. "I guess I'll just head home."

As he walked out of the building, he thought about what happened earlier.

'I can't even begin to believe that when I tried to access the Heavenly Dragon power outside of Balance Breaker that happened, well at least I still have that.'

Kaii also silently reflected on why he didn't tell anyone that he was temporarily sent into the past, and what happened there.

Hyoudou Residence

"The hell is this?!"

Kaii was treated to a sight he wasn't looking forward to seeing, and that was Azazel being in the living room with Rias' entire peerage, Ravel, Irina and Ophis (who had began living with them) all with packed up bags on the floor.

"We're going on a vacation apparently." Xenovia said as he lifted up her bag.

Rossweisse, who was more embarassed, than angry at Kaii now, avoided him.

"Yup! We'll be back in a few days! Ciao!" Azazel said as they all disappeared in a magic circle, leaving Kaii with a deadpanned expression.

"...Thanks for inviting me ASSHOLE!" He screamed at the top of his lungs.

"Ara, keep it down."

Kaii turned around to see where the voice came from.

"Oh, Hisui."

Hisui was with Alice at the top of the stairs, looking down at him.

"What are you guys doing here?" Kaii asked.

"We're all here until they get back." Alice replied.

"Oh, well if that's the case, I'll take a walk then. Where is Pandora?"

Alice answered as she walked away. "She's out for a walk as well."

As Kaii walked out into the yard, he felt a massive chill go down his spine.

"...! What was that!?"

He turned around to look at the house, and realized that no one else was noticing this.

"Why aren't they feeling this? It's coming from the park... Pandora is there!? Shit...!"

Not caring who saw, Kaii's wings appeared behind him as he took off like a jet.

5 minutes ago, the Underworld

Ajuka was in his lab, along with his partners, who were monitoring parts of the world for abnormalities, particularly Sacred Gears.

One of his fellow scientists was twirling around in his chair, until something caught his eye on a radar.

"I've got something! Coordinates: 3000 by 4000. It's in the Gremory territory!"

"Could it be?"

Ajuka came over to the radar and made an excited face. "So they've finally shown up..."

The Park

Pandora was wearing casual clothes as she sat on a bench, relaxing, until she looked up and noticed in the center of the park, a literal rip in space was opening.

She walked up to it carefully, and realized no one was in the park.

'As if that's a coincidence.'

She quickly jumped back as two figures emerged from it.

One was a fairly slim man with narrow eyes with short, dark hair with pointed bangs hanging between his eyes. He was wearing a white jacket, a black sash and a white hakama. His jacket had a slightly tall collar that he left open to his upper chest, along with him having a sheathed sword on his waist.

The other was a familiar dark green Western Dragon with silver eyes, and was standing on its hind legs.

"This human world is so boring! Maybe I can liven it up a bit!" The Dragon shouted.

"Stop whining. I said I'd be fine on my own, but you insisted on coming along, Grendel." The man in the white jacket said.

"You're no fun at all." Grendel pouted, but not before he huffed his breath and opened his mouth, letting a pillar of fire fly into a nearby forest.

DOON!

"Anyways, who are we after? Multiple people?"

"Just one, we can leave the others." The man said.

Pandora, who was hiding behind a tree on the other side, applied magic to her eyes and stared at the man, only to see the number "11" floating above him.

'The eleventh Demon huh...'

"We have to find a single bug in this whole nest of them?!" Grendel exclaimed.

"It won't be hard. There's only two of his kind in this town."

Grendel walked around a bit, until a narrow white beam went flying horizontally towards him.

"Whoa!" He ducked to the ground as it went right by him.

Pandora revealed herself as the one who shot it by walking out.

"Cain! Is she the one!?" Grendel yelled.

Cain looked forward with his hands in his pocket, sighing. "Grendel, if you had invested even the littlest amount of time into your observational and reasoning skills it would be obvious to you that..."

Pandora then felt a huge chill go over her body.

"...She is trash."

"In other words..." Grendel started with a grin.

"...Kill her."

Grendel laughed psychotically as he send a giant bomb of silver flames at her.

Pandora stood up and put her left hand forward, as multiple lines, both horizontal and vertical appeared. When the flames got close, the lines grew in size and flew forward, hitting the flames.

"What?!" Grendel yelled, as his flames were destroyed by the lines.

Cain looked over to her with his hands in his pockets still. "That was interesting...! GRENDEL MOVE!"

Grendel once again dropped to the ground as Pandora's lines kept traveling forward, slicing and dicing everything in their path.

The lines were now heading towards Cain who looked forward with a bored face.

All he did was put his right hand forward.

SCREEEECH!

In that moment, he stopped her lines with his hand, leaving barely a 3rd degree burn.

"What should I do Cain? This one knows some pretty interesting moves!"

"That won't be necessary Grendel. Kill her."

"Gahaha! Right!" Grendel yelled as he went to attack Pandora.

CLANK!

Grendel stopped right in his tracks as he felt something sharp in the palm that he was going to use to attack her.

Kaii appeared in front of her, with his Muramasa forward.

Pandora had a slightly awkward expression aim at him. "Kaii?"

"Sorry I'm a little late. I'll take these guys out real quick." He said as his sword began glowing.

Grendel backed up, and scratched his head. "A sword? Hey, Cain! Is he the guy?"

"Surprisingly no. I'm ever-so shocked that your flailing about didn't draw him out. Our target is an Angel."

Kaii went to slash at Grendel, but...

"Is that all?" Grendel asked with a bored voice.

Kaii was shocked to see that his sword barely left a scratch on Grendel's skin.

"-As I was going to say, Grendel." Cain started.

SMASH! SHATTER!

Kaii's jaw dropped as his prized weapon was broken and shattered into pieces by Grendel's hand.

"-He's also trash."

Cain looked at the broken sword with an indifferent expression. 'That was weird. For a split second, when it broke I felt the leak of life force from it.'

"Uh, Kaii?" Pandora asked.

"What?"

Pandora made an awkward smile as she scratched the back of her head.

"I didn't exactly need help..."

Kaii looked back at her, and started blinking rapidly. "Eh?"

"Yeah I can- LOOK OUT!" She yelled.

Kaii spun around as Grendel slammed his fist into Kaii.

"Guh!" Kaii spat out blood, and felt some of his ribs snap.

"You're finished, brat!" Grendel yelled as he went to attack once again.

A dust cloud appeared around them, and when it settled, Grendel noticed his attack was stopped by a blue magic circle.

"Hello there!" A voice said from behind the magic circle.

Kaii looked up and saw Ajuka and Serafall in front of him.

"Sorry I'm so late, Kaii-kun." Ajuka said.

"What is this?" Grendel asked as he puffed a tiny flame through his nose.

"People just keep popping up and getting in the way! Do you want me to kill you two first!?" Grendel screamed.

Grendel once again went to attack, but Serafall put one hand up, as a giant pillar of ice appeared beneath him, sending him up into the sky. Following that, she put her hand down as a pillar of ice formed above him in the sky, sending him spiraling to the ground.

"DAMN YOUUUU!" He yelled as he went to attack them yet again.

CRASH!

Another dust cloud kicked up where he attacked, but when it cleared, no one was there. To his left, Ajuka was standing by himself. To his right, Serafall was holding Kaii over her shoulder, with Pandora behind him.

Serafall moved her free hand downwards as a huge block of ice dropped on Grendel's head, apparently knocking him out cold.

As Cain observed the situation, Ajuka noticed one of Grendel's claws twitching.

"You're a poor loser, aren't you?" Ajuka asked.

"SCREW YOUUUU!" He yelled as a silver fire gathered in his mouth.

"...!" Serafall's eyes widened as she noticed his silver flame rapidly increasing in power, as if it was heading to a breaking point.

BOOM!

Grendel attacked with full force, sending the massive fire towards Serafall.

A huge explosion followed, leaving a small mushroom cloud.

"AHAHAHA! TAKE THAT! THEY WERE BLOWN TO BITS! THERE'S NO WAY SHE COULD HAVE DODGED MY FLAME AT THIS DISTANCE-!"

Grendel's silver eyes widened as he noticed Ajuka standing in between them, with one hand forward, blocking the flame.

"What the HELL?! Who are you!? How did you do that?!"

Ajuka made a sly smile in response, as he brushed some of his hair back. "It's called my special Kankara Formula. It has the ability to control all phenomenon using equations and formulas to modify it into something else, be that even an attack of my own. All I did was modify your attack to go sideways, rather than forward." He said as he pointed down.

Grendel looked down with a shocked face as he saw a huge ravine in the ground, branching out in opposite directions, from left to right, rather than forward.

"What did you say?" Grendel asked in a more calm voice.

"Would you like to see it again? Maybe this time I can turn your attack against you." Ajuka replied. "Like this!"

Ajuka then fired a large blast of Demonic energy right at the Evil Dragon, until...

Cain disappeared and reappeared in front of Grendel with speed so fast, it seemed like he froze time temporarily, blocking Ajuka's attack with his right hand, and sending it up into the sky with ease.

Ajuka made a difficult expression, as he analyzed the Demon. 'He moved with speed that exceeds my own, and deflected that with no troubles. He still has his other hand in his pocket, meaning that wasn't even worth the effort for him...'

Grendel looked down and made a confident grin. "Cain..."

CRASH!

Cain turned around and bashed his right elbow into Grendel's stomach, sending him flying meters away into multiple trees.

Grendel stumbled over as he tried to stay conscious. He had tons of blue blood coming from his mouth as he stood on one leg.

"What the hell?" He asked with a weak voice.

"You idiot. You're getting in over your head. Those two Devils are Serafall Leviathan and Ajuka Beelzebub, with the latter being a Super Devil. You can't beat them. Furthermore, you disobeyed Tenma-sama and attacked Kaii Valefor. We're leaving." Cain said as he walked back and used his hand to open a rip in space.

"Running away?" Serafall asked.

Cain turned to her and made a sarcastic smile. "I'd like nothing more than to crush you all. But it's more than obvious which of us has the advantage, especially when you have trash like those two on your side. Grendel, we can always look for the Angel another time."

"Right..." Grendel moaned as he walked into the rip, disappearing with Cain.

Ajuka looked back to see Kaii staring at his broken sword with an angry face.

"There might be something I can do about that."

Europe, far in the mountains

Azazel and everyone else on "vacation" appeared in a very snowy mountain, appearing to be desolate of all life.

"What the... is this the wrong place?" Rias asked while shivering.

Azazel turned back to them. "Oh, sorry. This isn't an actual vacation, more or less a meeting."

"A meeting?" Koneko asked.

"Our weapon against Tenma, the leader of the Qlippoth to be exact, they should be here any moment."

After about 2 minutes, a figure appeared behind everyone, and the heavy snow stopped.

"Azazel of the Fallen Angels, it's been a long time since we last spoke." A voice said.

Rias turned around and her eyes nearly popped out of her head, as she started stuttering. "N-No way, th-that's..."

A figure that appeared to be a child walked up to them, although the child seemed to be very mature.

Azazel made a smirk at his appearance. "Everyone, meet our secret weapon. The God of Destruction, Shiva."
