The Great Demon family of Naberius was an influential house in the Underworld when it came to innovation. Many of them were the greatest scientists of Devil kind. The Underworld would be not be as good as it was without them. Yet, that was all in the past. Their numbers had dwindled greatly after the Devil Civil War where many of them were killed in rushed experiments or assassinated by the opposing sides. Now the Clan was a shadow of its former self.

Oh there were still enough for a small healthy population, but still. Most of them were ordinary with only a few exceptions these days. While the Clan still had quite the influence, it wasn't enough for some of them. In particular, one Nazar Naberius.

Nazar wasn't much popular in the family. Well he wasn't much popular anywhere. His fanatic drive to re-establish the family as one of the best in the Underwolf turned off a number of Devils. Of course this was more so because people found him rather creepy. Given that they were all Devils, this was saying something.

Nazar was a prodigy when it came to all sorts of magic. He had studied for centuries to understand and manipulate the magic of this world. Well most of it. Japan, while still allowing devils inside, was secretive about their magic. While the three factions were rather strong, the Shinto faction had given the angels a bloody lip many years ago during the Christian conflicts in the nation. The Devils and the Fallen Angels had fallen prey on occasion as well when they had made bold moves.

That was in the past however. The Shinto faction wasn't as strong as it used to be, or else no Devil territories would have been set up in the nation. This was perfect for Nazar. It's why he was currently choosing targets for experimentation within the country without abandon and what luck he had! He had two Nekomata under his thumb. Not just any Nekomata, but Nekoshou! The last two on the planet.

Oh that excited him like no other. There were no end to the experiments he could perform on them. Of course, during the whole encounter, the elder sister had been badly wounded. Not his fault of course. They were too valuable to damage. At least, not yet and without the right equipment. No it had been a stray devil that used to be under his employ. It rebelled because of some bit of 'morality', whatever that was. What had been one failure had born his greatest triumph.

So he had to reincarnate the elder Nekoshou. It was quite the feat. He had to use his only two Bishop pieces to do it. It was well worth it. Oh there were so many things he was willing to try and had started to plan and attempt some. Only small fry experiments. Nothing to push her too far, although she already didn't like him. That didn't matter. While she was a Nekoshou, she was also a Devil now. Not exactly a pure specimen.

Her sister however was and that was why he was willing to start pushing the older sister. He would not lose the younger sibling to a miscalculation. If he had to cut up the older sister into pieces to make them all work, he would. He was going to get his family back on top.

Nekoshous were indeed one of the most powerful yokai. To have them in possession allowed him to access types of magic he never thought would be possible. Of course, he decided that wasn't enough. Nazar wanted more. He wanted it all. To reach the greatest of all power. He cursed the Shinto gods for he knew they hid something more from him. Thankfully, he had the tools to find it now.

The sight of the now dead yokai didn't really thrill him. He was a powerful Devil after all. Oh yokai were dangerous, even at low levels. They were tricky and feisty, but so were all pagan creatures. Perhaps they didn't think anyone would locate this small shrine. Well they hadn't counted on a being as intelligent as him sticking his nose into their business. A shame. A couple of them could have been good test subjects too, but there was no time for that. He had his goal in sight.

With that in mind, he glanced over at his little helper. The Nekoshou known as Kuroka. Such a powerful beaut as she was hitting puberty and he knew she would grow even prettier as she grew up. Not that he was interest of course. She was some lowly yokai and not a pure Devil. Still, he could always experiment to see if he could replicate such looks in a Devil. Perhaps he'd take some of her flesh later. Although, he'd have to wait till he knocked her out. She wasn't pleased with him with her snarling glare that she sent his way. She was so annoying with that hatred. She should be proud that her body was being used for science and progress.

That's when he heard someone gurgling. He looked over to see one of the Nekomata yokai was still alive and trying to crawl away. Nazar moved over and put his foot on the fellow's back, causing the nekomata to cry out in pain as it had a large slash going down right next to its spine. Nazar felt a little bit amused and thought of something.

"You know," Nazar looked back at Kuroka. "I was wondering about the effects of your Senjutsu when used against other yokai. I think that 'Touki' technique would do? A good strength boost could make this quick."

Kuroka's eyes widened. She hadn't been forced to kill these yokai. Nazar may not have been the most powerful Devil, but his bloodline still allowed him to access quite a few techniques that made even her nervous about confronting him. She glanced towards the downed yokai and shook her head.

Nazar growled and used the cane he was holding in his right hand to tap it against the nekomata's skull beneath him, "I said, kill this yokai with your Touki. It's very simple, Kuroka. I've seen you do it before." He held up his hand and let a bit of devil fire light up. "Shall I help motivate you again?"

Kuroka shook her head again, "I won't… I won't kill him."

"You won't implies a choice," Nazar commented as he put out the flames. "Such as whether or not your sister will be helping with my next experiments."

Kuroka's eyes widened, "No, you promised. You promised you wouldn't touch her."

Nazar smiled. Oh he had promised her. The young lady had bought. Well not exactly bought it, but she was hoping he'd be too busy experimenting on her to go after her sister. With such a young and untainted specimen, that wasn't going to work but still. He wouldn't push her just yet. He chuckled, "You're right. I did promise, but you are my Bishop. I expect you to do as I say or you will be changing the nature of our pact. Do you want to do that? If you do, I see you don't care about your sister as much as I had thought."

Kuroka bit her lip as she trembled. Nazar knew that was from both fear and sadness. He didn't really know those feelings but he saw them often enough to spot them. He had to keep a close eye on his experiments after all and it paid to know what they were thinking. So the Nekoshou finally walked over to the yokai. Her body was enveloped by her aura and he could feel her strength increasing. Then she struck.

Her clawed hand slashed through the yokai's skull like it was nothing, slashing it to pieces. The moment she did, Kuroka let out a little whimper. Then she quickly drew back and looked at the blood on her hand. Nazar rolled his eyes at her action before grabbing one of her ears and pulling her into the shrine. He ignored her pained outcries like he always did.

He pushed his way through another door using his cane. The moment he did so, Nazar's eyes widened. Right there in the middle of the room was a crystal orb. Energy of all types seemed to exude from it, showing in a rainbow of colored vapors inside the orb. Nazar's eyes widened as he grinned.

He eagerly moved forward and put his cane right up against the pedestal that the orb was on. His hands played around the orb, sensing the power within. He knew this wasn't just any magical orb. This one was special. Oh so special if his research was correct.

This orb housed the power to transcend to another plane entirely. One that housed so much potential for experiments that he almost came from the very thought of them all. He started to chuckle with his victory. With power like this, his experiments with the Nekoshou were about to become child play. That didn't mean he'd stop with that of course. He never half finished with something and using the two last Nekoshou's on the planet was something he still thought of with glee. He wouldn't just be a part of the best of the Devils.

He would be the greatest of all. Now he just had to start.

Back in his lab, everything was set up. The place certainly fit the psyche of the mad doctor. Several test tubes, some large enough and did house a number of creatures in liquid stasis, were strewn about tables or on platforms. Lights and machines beeped and lit up the room as different programs ran through them. Right now, none of them were his focus. It was the casket in the middle of the area that was his focus.

The casket was rather large and metal plated, with Devil writing written all across the blood red finish. Said Devil writing had mystical properties that were meant to house and hold a creature of immense power and give it life. Something that fit perfectly with what he had planned. Above the casket was the orb. Several tubes were connected to it that ran right into the casket.

In most cases, a casket like this would be used to bring back a recently deceased Devil. It was devised during the great war against Heaven. Of course, not many of them were produced given that it took too long to create one and the original creator was destroyed alongside his workshop by a team of Angels. So the Devils didn't really pursue it afterwards with only a few caskets surviving. He had been able to get his hands on one through a number of means, some of them weren't legal of course. Still, he was a Devil. Why should he worry about legality? He found it silly how most Devils these days thought about 'morality' and tried to be 'nice'. Pah. Weaklings the lot of them.

Now he had reconfigured the casket with his own genius mind to create a body from scratch. Oh he couldn't wait. Where did the get the idea? Well he had of course been searching for a means to use the orb and he came across some writing. It would seem that one such area that he could grab from was a well of souls. A place that interconnected with other dimensions and was the place the dead lay after all was said and done.

Not just the dead however. Because it could be influenced by the thoughts of souls, it also housed the images and creations of beings that never existed before but did in the mind. He went gaga. It would seem that this place was being investigated by Heaven and Lucifer was one of the beings in charge of the project. Even he, the Great original Lucifer, was wary of it. Bah! He would surpass him. Perhaps he could even bring him back to life. Oh the looks on all of the Devils faces when the first Devil thanked him for giving him life.

That was a future idea. For now, he had to see what it could do. That being said, he needed to bring something over first before going haywire. Unfortunately, he didn't have much of a catalyst so he was going into this blind. No matter. Once he grabbed a being on the other side, he would use its blood to form new and more powerful summons.

As he looked over his book, he noted how it had been a few weeks since he had gotten the orb. He needed to get results. He flipped the pages and grinned. "Ah yes. A little bit of blood."

He would not use his own blood. If he summoned a Devil at this stage, it might be used against him by another faction if he brought back a relative or they would put pressure onto him. He worked at his own pace, not theirs. So he would need the blood of one of his experiments and he knew just which one he needed.

The inside of Shirone's room was filled to the brim with fluffy cat items. There were cat face style pillows on top of her fluffy bed and cat pictures about. It was all in all a very cute little room. It was something Kuroko didn't mind, even if it was a bit much. It made her little sister happy and that was enough.

She would have felt happy herself if she didn't have to worry about that Devil hurting her little sister. That very thought made her hair stand on end. Still, he promised. She could only hope he'd keep it.

Currently her little sister was sitting on the edge of her bed holding a stuffed white kitty. Her little dangling legs were kicking back and forth in anticipation as she watched her big sister, "Kuroka, what is it? What is it?"

Kuroka giggled and wagged her finger, "So impatient, my little kitten. I thought I raised you better." She continued to giggle when her cute little sister pouted. "Alright, alright. I'll show you. It's a little trick I've been working on."

Kuroka closed her eyes and focused. Manipulating the energy of the body could be rather difficult and even dangerous sometimes. It didn't help that the special techniques she had, Senjutsu and Youjutsu, were rather dangerous techniques and you could get lost in your primal instincts. A rage like no other, which was why she was hesitant to teach her sister just yet. When she got older and had a stronger body though, she would with a glad heart.

As her energy moved, she felt some slip away. Perfect. She moved her hands together, preparing to separate that segment of energy. When she opened her eyes, she spread out her hands and in an instant, a copy of herself appeared by her side.

Shirone gasped, "Oooooh, that's so cool!"

The two Kuroka's giggled and bowed, "Thank you~ Anything to please my little kitten." Seeing the bright smile on her sister's face was always a highlight in her life. Kuroka leaned towards the clone and clasped hands. She hefted her up and now the clone was holding her hands while upside down. Then she pushed her up into the air, before the clone landed on her hands.

"Yay~" Shirone cheered.

The clone then summoned up a ball of energy and threw it up into the air. It repeated that twice more and soon it was juggling blue balls of fire magic. The little Shirone was clapping her hands in delight as she giggled. The sound made Kuroka's heart leap with utter joy.

That is until the door opened and she heard a familiar voice, "Ah, I see you're teaching your sister a new technique. Most impressive. I'll have to see how that works later."

Kuroka dispelled the clone and turned to glare at the creepy Devil. He had saved them of course. Her crappy father had gotten himself and their mother killed in one of his experiments. Now she had ended up with another crappy scientist. At first she had been relieved but after his experiments had started… she started to shiver in slight fear. That fear multiplied when he looked at his little sister.

"And how is my favorite girl doing today?" Nazar smiled in his own attempt at being sweet.

Shirone was still only a little kid so she didn't notice how mean he could be. She smiled back, "I'm doing good, Mr. Nazar."

Nazar waved in front of himself, "Just call me Nazar, little one." He kneeled before Koneko, ignoring Kuroka's angry hissing. "Little one, can I ask something of you?"

"What is it, Mr. Nazar?" Shirone cutely tilted her head to the side.

Nazar pulled out a syringe which made Kuroka go still, "I just need a bit of your blood. Don't you worry, it won't hurt."

Shirone frowned, "You promise?"

Nazar put a hand on her head and scratched her ears, "I promise." He smiled, glancing at Kuroka who was glaring at him intently. He held her arm in his hands as he moved the syringe closer. A little magical spell dulled Shirone's pain so he could extract the blood easier. Pulling the full syringe away, he patted her head again. "Now that wasn't bad, was it?"

Shirone shook her head, "No it wasn't."

"And this is for you," he pulled out a cat shaped lollipop.

Shirone gasped and smiled, grabbing it. "Thank you, Mr. Nazar."

"Anytime," Nazar chuckled and hurriedly exited the room.

Kuroka couldn't help but clutch her sister to herself the moment he was gone and the door shut. Shirone stared at her in confusion. To Shirone, he was a nice man that cared about them. To Kuroka, she knew the truth. Telling her sister wouldn't be the best choice because he would find out and they would both suffer. She just hoped he would keep his promise.

Nazar hurried into his laboratory. He had the last ingredient was in hand. The Devil scientist rushed over to the casket. He pressed a little sigil on the side and immediately, a hole opened up in the middle of the casket. He quickly squirted all of the blood into the casket and then closed it. He took a couple of steps back and waited with baited breath.

For a moment nothing happened. Nazar scratched his head and was about to comment about that before the orb started to light up. Energy started to pour down through the funnel as the casket started to glow. The Devil words lit up and the casket started to shake. He could feel a surge of power starting to form from within the casket, exuding its presence to the world.

Nazar spread out his arms and laughed, "Oh yes. YES! Finally. After weeks of research and preparation, it has started!"

Just as quickly as it started, it ended. Nazar hesitantly waited. He wouldn't rush right towards his project just yet. He had learned quite a bit from previous experimenters that it was best to wait till you were certain it was safe. Eventually, he decided it was time. He walked over the casket and pressed three sigils on the top half.

The casket pulled slowly to the side as it opened. Nazar's eyes widened as his grin started to split his face from ear to ear. Right there before him was proof that his experiment was a success.

Right inside the casket was none other than a heavily tanned boy around Shirone's age. His white hair was short but spiky. Nazar was a bit curious as to why he was clothed. He didn't think that would have developed but he didn't care. The red cloak with black clothing underneath was Devlish enough. He idly pondered if the cat tail and ears were created by the blood transfusion but that was beside the point.

He had created life. He wanted to laugh and cry at the same time. Oh this was perfect. A few months from now, after some very thorough tests, he would create something even more spectacular.

"Just you wait," Nazar grinned. "Everything is going according to plan. It is fitting you were summoned into Hell because I don't think you're going to enjoy your life here. Sucks to be you~" He laughed.

Hello and thank you all for taking the time to read this story. I hope you all enjoy it and I can't wait to read your feedback. This is my first story concerning Highschool DXD, so I hope I get the characters right. Comments on the story are appreciated and help me greatly improve on my writing.

Just a few things I'd like to remark about this story. First things first, Archer (and when/if I decide to bring in other servants) will not be OP in comparison to the other beings of DXD. I honestly prefer balanced crossovers and he will be challenged as time goes on. Of course, that isn't to say he won't get in a few battles that slide more so his way either. Just something I've noticed with some crossovers and I won't be playing that here.

Secondly, there will be a romance(s) with crossover elements later on but as of now, haven't chosen definite pairings. That will change as I go along.

I hope you all had a good time reading this and have a great day.
