Infinity, a concept with possibilities that surpasses even itself, there is not only one infinity but countless others as well, ranging from the simple 1, 2, 3… to the most complex ones. One of which was the Nothingness of the Infinity, or simply Nothingness, this Infinity is one of the most, if not the strongest infinity that has ever existed in the Universe. Although very sedentary for most of its life, it does have its own name. Known as Ophis, or the Ouroboros Dragon, it took form of a young girl in a gothic Lolita outfit but lest this must not fool anyone, since her strength is incomparable with anybody in existence, except for two…

Her existence was purely on the sole reason to rest in the gap between worlds, a place not known by anybody but few. Although she left her home, those were greatly rare occurrences and the reason would always be that she wanted to see what was happening on the planet. But when she did visit, she would remain nonaligned as much as possible, but after one random visit, another entity whom has the power equal to hers appeared and settled in her home with no guilt of transgression. This act greatly displeased her and this led to many other attempts of exclusion for the intruder, but due to their equality or closeness in power, this also led to many failures. So she left her home with great irritation to seek for mortal assistance.

All she wanted was to retain silence, something she had bathed in for millennia, so she would commit anything for her to achieve silence again, even though she would have to work with some mortals. Well that was supposedly her plan, but she didn't expect a new presence that would come into play.

For six short years, she had sensed these… short bursts of energy. Although, its signature was so weak that she wouldn't even know about it, but as time went on and her senses had now caught up with it, she began to worry. In her description, it was an energy that felt so unique yet so aged. This she never felt even once in her incredulously long life, but it still felt so familiar, so contradicting with her, so much that it felt it was the complete opposite of her. The signature was so pure and fulfilling, yet endless as if it was created just for the sole purpose to contradict with her. So to this day, she knew she had to investigate whether this energy was against her or not; because if it did, she would've another problem in her hands.

For her to examine this however she had to know its exact location, and luckily for her; that would be the easiest part, it's like saying whether a light turned on. So as she sat in the darkest yet silent place on the planet, she patiently waited for the energy to return again. And that's the second easiest part for the Dragon, patience was basically her last name (not literally), legend has it even that she waited for hundreds of years just for a single tree to fall down due to gravity, reason why she did that was unknown.

A few uneventful hours passed and Ophis still waited for the signature to reappear in her senses again, until in one random moment, she felt a tiny energy spike due south of her position. It was so weak in fact that she wouldn't even notice it if she was not to be careful. Yet so, she pinpointed the location before she warped herself to the source of all her worry.

When she arrived, she found herself in an empty park, where a dusty fountain was constructed on the middle of the square with four benches that was carefully bolted to the ground around its four sides. Her attention then shifted to the source of the unique signature, before she found herself staring on a lone boy that sat comfortably on one of the benches. His body exerted a cheerful aura and malice was practically inexistent in him. Interested further, she sat beside him and was able to more accurately tell his intentions and physicality, his height was a foot smaller than her, so she easily looked down upon him; whom already caught her presence. "Good morning lady!" A smile reached his young face as he playfully swung his legs on the bench. Another surge of this unique energy she felt from the boy again, it was definite that it came from this young boy but this gave her a dilemma, more so her first ever dilemma in her entire life. She didn't know how to handle this.

This young mortal seemed to be too naïve about his unique powers yet and from the still cheerful expression he exerted, it also appeared that he didn't even know her or how dangerous was she. "Umm lady? Are you feeling alright?" Her sudden train of thought was broken but this didn't remove her gaze from him, all this that happened made him slightly creeped out with the lady beside him, but he was taught strictly to not tell these kinds of words. 'What would I do?' Her gaze then moved from him to the distance as she carefully pondered her decisions, it was obvious that this mortal would become incredulously strong one day, if he was to not get killed of course.

'Hmm, if I were to kill him now then I would waste the chance of making him my ally, which judging from this unique power he had, would be really crucial if I wanted eternal silence. But if I left him alone, bare to the world, then someone could use him against me in the future, which could harm my silence drastically. *sigh* For now, I would watch over him and let time do the rest.' After she reasoned with her consciousness, she then moved her gaze towards the boy who also stared back in curiosity. There was one way that would ensure total observation.

Their eyes watched each other for a moment before Ophis' smooth hand slowly cupped the young boy's cheek and moving her face closer to his, all this with no resistance but a single question from the boy. "Lady?" She then pressed her lips against his, but this sent a surge of energy through her whole body, a sense of utmost pleasure as they remained connected through lips. Her thoughts drastically changed from seriousness of observation to a lustful advance to claim him as hers. Her lust spiked to levels that she could not comprehend, so much she pushed the boy down as she continued to ravage his innards with her tongue. All this happened with no resistance yet again from the boy as he let himself get dominated by her.

Ophis felt his unique energy inside of her but she didn't care about it, all she cared for was this pleasurable sensation that rocked her body like a ship on water. But sadly all good things had to come onto an end, a directed spear of light narrowly passed her by a hair strand. She pulled away from him, a trail of saliva still connected from their lips. 'I need him, he would be mine.' Her gaze lustfully searched her now self-proclaimed soon-to-be mate, as a small smile reached her lips when the symbol of infinity was engraved nicely on his neck. She then stared at the angel that just intervened in her business, whom was filled with nigh infinite rage. "Soon enough" Ophis boldly stated as she disappeared from sight.

Raynare lowered her guard and flew to Issei to check if he was harmed by the unexpected visitor. She breathed a deep sigh of relief when she heard his breath, but something else caught her eye, Ophis' symbol of Infinity; which was engraved at the base of his neck near his shoulder. 'What are you up to, Ophis?' She tried to remove the mark with her magic which ultimately failed, moments while she did this she heard voices and footsteps approach the scene and Issei was beginning to wake from his slumber. So with no other choice, she quickly set an illusion specifically to hide the symbol before she disappeared from sight. Issei groggily rose from his position as he observed the surroundings with a confused expression, but when he caught sight of his two friends, almost immediately a big smile reached his face as if nothing has happened earlier. "Koneko! Irina!" He slid off the bench and ran towards his two friends to spend the day with them, while Raynare whom was more alert because of the unusual occurrence; watched over Issei very carefully.

But unfortunately when Issei arrived, he was dragged into a middle of an argument where he couldn't say a single word between his two female companions, or his scary friends would surely kill him on the spot. "Issei is going to the playground with me!" Irina complained as she pulled on his wrist, as she tryed to overpower the other female whom also pulled on him on the opposite direction, it was like a game of tug of war where he was the rope and the two were the contenders.

"No! I and Issei had already planned to go to the toy store! Right Issei?" Issei turned his head and inwardly gulped when he saw Koneko's incredibly cute puppy eyes, which effectively hypnotized him to do its bidding. "Umm, Koneko and I did plan to go to the toy store Irina, how about next time?" Irina pouted as she released her grip on Issei. "Next time then, Issei, promise!?" He scratched the back of his head while he awkwardly laughed.

"Of course, I promise" He then showed his natural smile in response, which sent a jolt up Irina's spine and a small tint of pink on Irina's cheeks. "OK… Bye then Issei and Koneko!" She hurriedly ran away from them to avoid further embarrassment from Issei, often did he disarm her with that smile. Her disappearing form was observed by Issei's confused gaze and Koneko glare, but it only took a second before Koneko diverted his attention towards her, her glare was replaced by an energetic and happy expression.

"Let's go Issei!" She then pulled him towards her designated location. "OK! OK!" Before he knew it, he was being dragged by Koneko across the now silent park. All this happened while Raynare; whom was furtively hidden among the trees amusedly watched the display of friendship between the three; she stayed for a moment or two before she followed after to guard them from any sneaky threat and not let what happened earlier with Ophis occur again. But before she could even follow through her plan, a bright ray of light shone through the heavens above her. "Raynare, I need to speak with you" Raynare looked at the two for a quiet moment, worrying for their welfare before she reluctantly disappeared to discuss with God.

It took half an hour to reach the local toy store and by that time Issei and Koneko shared some hearty laughs with the boy's jokes and the few stories that were passed between them. "We're here!" Koneko's eyes sparkled like stars, as she saw the rows after row of cabinets on each wall of the site was filled with brand new toys and gadgets. "Koneko, mommy said not to waste all our money in buying toys" Issei grabbed ten thousand yen from his pocket and showed it to Koneko, whom was pretty disappointed that she could not get the better looking toys. He noticed this and patted her head softly; her pale white bangs covered her beautiful hazel nut eyes.

"Come on, we have lots to buy with this!" He softly slid his hand into hers before they ran into the stuff toys section. "Issei!" Their enthusiastic gazes searched the contents of the section before they ran to different directions as they found something they liked.

A couple of minutes passed and they returned to where they started with toys, Issei returned with some plain teddy bears while Koneko held what looks like a bird colored in blue. "What's that Koneko?" He examined the toy in interest while she hugged it tightly on her chest. "This is from my favorite show! Ever heard of Pokemon?" Even though Issei's knowledge of such show was vague, he nodded because he apparently always agrees with Koneko, no matter the situation. "Well what kind of Poke-mon is it?"

"This is Articuno, my favorite Pokemon, can we buy this please?" Again with her puppy eyes, Issei sighed and looked at the price tag. 'Nine thousand yen?!' He wouldn't even have enough money to buy a toy for his own, but when he looked at Koneko whom was literally begging for him to buy, he had no other choice but to agree with her, anyways he had plethora of toys back home. "OK, let's go to the counter" He smiled as she literally jumped in joy.

"Thank you! Thank you!" Unexpectedly, she ran up to him before she gave him a chaste kiss on his cheek which utterly surprised him, but before he could question her; she ran off towards the counter. "Koneko these days" He scratched the back of his head in confusion before he followed after to pay for the toy.

After Issei paid for the toy Koneko wanted, they went out of the shop and walked back towards their home. During their journey, he couldn't help but smile at her while she cutely hugged her toy with her two arms. They passed by the old park again, but instead of it being void of human life like earlier, there were four men standing by one of the benches.

Issei felt an awful feeling from them; so he did redirected Koneko's course to go around the fountain now instead of going straight forward. "Issei?" He redirected his gaze towards her with a smile; so she couldn't notice his worry. But before they could fully make it through, the four men with an aura obvious of malice and evil quickly surrounded them.

"What do we have here? Two young lovebirds, hehe" Issei and Koneko looked at them in fear which stopped them from their tracks, like wolves hunting some fresh deer. "Stay close to me Koneko" He looked around for an opening or a chance to escape these terrifying people, but before he could think of a plan, he was suddenly pushed down to the ground. "Now what do we do with this pretty girl?" Issei was then bounded down when one of the men stepped him on his stomach so he could not escape.

Issei tried to remove the foot on his abdomen but it was too strong for him to even budge. "Watch kid, you'll like this" "No!" He outstretched his hand towards Koneko, whom was being overpowered by the other three men. "Issei help!" He tried to send a small flurry of punches on the man's leg but he only stepped on him harder, which stopped his attempts.

Koneko kept screaming as she was held tightly by the other two men while the largest one slowly undressed her. "Issei!" She closed her eyes, it was happening again. She was going to be deflowered now with no hope of escape, she was promised that she would be protected, that she would be loved dearly but…

"Koneko!" A pair of arms wrapped itself around her neck as she opened her eyes in pure shock. Issei was hugging her and the four men that tried to lavish her were gone. "I'm sorry that I couldn't save you sooner" The boy cried in her neck, this action snapped her out of her thoughts before she hugged back. "It's OK" The day was setting over them and the wind was beginning to blow; their parents would've been worried sick for them. "Let's go home, shall we Issei?" She wiped off his tears before he nodded in agreement. "Let's go" The sounds of footsteps were heard after that, as Issei kept himself near her as much as possible while Koneko looked at the ashes that blew by the wind in wonder.

"Hey do you still have the toy you wanted?" He asked her quietly, before she realized that she might've dropped it since it was not in her arms anymore. "Articuno!" She suddenly jumped in surprise but before she could return back to get it, Issei beat her to it and ran back to get her fallen toy. She smiled at him, even though all the things that happened; he could still keep a smile.

AND CUT!

Now, this officially ends the Prologue Arc, this introduces Ophis and gives a hint of a new OC coming into the fray, but let me tell you that she isn't a human. Koneko is a few years older than Issei of course and her mindset is quite mature, but nonetheless her body wouldn't change that much; be it to the reason that I made it so that demons (Nekomata are Cat demons if you don't know) live a very long life, physical bodies would take quite a long time to develop for them.

Also, chapters would be a lot longer after this, around 4k or more and if you notice a line or grammar mistake then freely comment about it in the review's section. Moving to the reviews you left, I could only say Thank You! For the wonderful comments you left. If you ask, I would still keep this strictly for Koneko and Ophis but for other characters, like Asia, Kunou or even Raynare I would need to consider.

This is all I want to say for now, so please leave a review, or favorite/follow. All is welcome. See you in the next chapter. GBYE!
