Chapter XIII – Making History Part 1

They say that everything is possible, there was no such thing as impossible. Well, that was relatively true considering all the things one must do to make the impossible possible.

Imagination is what fuels progress. When man had imagined something from before, it was immediately considered a myth. Jump forward to a few hundreds or even thousands of years, then that simple imagination becomes a reality.

After all, early man thought that the Earth was flat. It took them a very long time to finally get that right. Man thought that it was impossible to fly. That is, until he managed to do it.

There were a lot of things humans had thought were impossible only to be proven that they were possible.

But there's one thing that shouldn't even be possible, right? Fictions, legends, all of that stuff was just rubbish...or at least, it was until the truth was revealed.

Oh yes, those little legends and myths you were told stories about and in those old books. They were real.

But that's not the point here. The point was, if given enough time and the right circumstances, even the most ridiculous of claims can become reality.

And right now, two individuals were about to make something that started out as fiction...into reality. And if and when they succeed...

They will write history.

Kyuren leaned back on his chair with a sigh after shoving his soldering machine in its proper place. He had been constructing the thruster boots needed for the flight capabilities of the suit.

He was wearing a simple grey shirt and some jogging pants.

At this time, he had completed the inner wirings and circuitry that had taken him a little over five days to accomplish, seven days in total when combined with the boot fabrication that took two more additional days. It took a lot of concentration and steady hands, but he managed to do it.

Fortunately, everything seems to have quieted down in the Academy so he and Sona could focus on their project without any further distractions hopefully.

Smiling to himself, the raven haired teen activated the boots and they opened up just as he wanted them to. He did it again for a few more times, his eyes watching for anything that could cause any mishaps.

Fortunately, nothing seems to be out of order and gave himself a pat on the back for a job well done. These boots were ready for some testing and further calibrations before he could start on the gauntlets.

'Wonder how Sona's doing?' He asked himself before taking a look at his partner over the hologram projectors and consoles. She was working furiously to integrate her new idea into their project.

Doing simulations on how to interface a person's nervous system into the suit.

She was wearing a shirt and a pair of shorts. Besides, what good would it do when her school uniform exposed her thighs. It leaves none to the imagination.

It was just like her own proposal, actually. She gained the idea that if they could interface the armor to the wielder's nervous system, then theoretically the systems could react faster than with simple voice commands.

Kyuren liked the idea, it saves them the work of having to code an assistance program or an AI for just that purpose. He could also see that it was a modified version of her own idea with the prosthetics, but on a grander scale.

He immediately agreed on it and asked Sona what she would need. The Sitri heiress just told him that she would handle it, and that he focused on the hardware while she on the software.

She was surprisingly talented at computers. When Kyuren asked, she said that it was just something she picked up on while her stay in the human world.

But that was days ago and she was burying herself in this. Kyuren could already notice the small bags under her eyes and the exhausted and frustrated look she had.

While he knew that it was important to her because this was her contribution to their project, Sona needed some down time. She had to take a break or she'll burn herself out and that was something they couldn't afford to happen.

Not at this juncture.

Deciding that they needed to take a rest, Kyuren deactivated the boots and stood up from his chair with a stretch to his body. Sitting on a chair for long ass hours really stiffens up the bones.

POP! POP! POP! CRACK!

"Ah, det er stedet." ("Ah, that's the spot.") He groaned in satisfaction, feeling the blood flowing again. After a few more stretches, he walked to the coffee maker and made himself two mugs of steaming hot coffee.

He walked towards where his partner was working and could see that she didn't even notice him. 'Looks like she's really determined.' Kyuren chuckled to himself.

Looking over, the raven haired teen saw that Pip was napping on Sona's lap and couldn't help but smile at how cute it was.

"Sona." He called out, nudging her shoulder. Feeling something nudging her gently, Sona turned her head and saw Kyuren holding out a mug of coffee. "Here, you might want this."

"Thank you." She smiled and took the mug and took a decent sip. Sona felt a little bit of energy coming back to her when the hot liquid traveled down her throat and sighed in satisfaction.

That was just what she needed.

Smiling, Kyuren leaned over the table and looked at Sona's progress. "So, what's the news?" He asked.

Sighing, Sona readjusted her glasses and set down the mug. "I've been trying to find a way to fully connect the nervous system to the suit, but it's tricky." She began to type again, this time a little calmer as her right hand was scratching Pip's head, making her purr in her sleep.

Kyuren smiled but paid attention to what his partner was saying. "How tricky are we talking about?"

"Very. This has never been done before, Kyuren." Sona admitted with a huff. "But I have something to work with." She opened a folder and the raven haired teen was surprised to see the US Department of Defense seal on it. "I based my prosthetics on the American's jet fighter neural systems program so I have something to work with. But I'm having difficulty with it."

The raven haired teen looked at the files before turning to Sona. "Ms. Shitori, that's highly classified information you got there. How'd you get it?"

In response to this, Sona looked at him with a deadpanned expression that clearly stated, 'Really? Do you really need to ask that?'

He promptly held up his hands in surrender. "Okay, okay. Forget I asked that." Kyuren chuckled before he noticed that she was rubbing her temples and frowned slightly. "Are you all right?"

Despite herself, Sona managed a shaky nod. "Yeah, just a little tired, but I have to finish this first." She was about to return to her work when Kyuren stopped her by placing a hand on her shoulder.

She stiffened at the contact. "Perhaps you should get a few hours of sleep first. You look exhausted."

Gently, the Sitri heiress shrugged his hand away and looked at him. "I appreciate the gesture, Kyuren, but I really need to finish this. It's my contribution to our project."

Well, she had a point there. This was her idea being combined with his own and when she succeeded, it would be a monumental success. This was her contribution to the team. But she looked like she hasn't sleep for some number of days.

"Be that as it may, you need some rest. We still have time, it's only been...what seven days." He reasoned.

Sona was about to protest until she yawned. She'll admit, she was tired. Devil or not, it was still draining to work for seven days with little rest.

Finally conceding to reason, the Sitri heiress nodded her head and Kyuren gave a smirk. "All right, but wake me up in a couple of hours." She said as she picked up a sleeping Pip and stood up before making her way to the sofa.

"How are things on your side?" She asked.

Kyuren smiled. "Why don't you see for yourself." He then lead the Sitri heiress over to his work station to show her the thruster boots he had constructed.

Sona had to admit, she was impressed. It was still a prototype, and she wondered that if it could function perfectly or not.

Noticing her unspoken question, Kyuren activated the boots and they hummed to life. Opening up like a flower as to accommodate a wearer then closing and locking itself into place.

Needless to say, his partner was more than satisfied with the results.

"Impressive." She said, staring at the boots. This was a new level of engineering.

"Thank you. If you want, I can fire up the thrusters for you." He raised a brow towards his partner and despite being exhausted, Sona managed to give him a halfhearted glare.

"I won't have you destroying my basement, Avynzen." She reprimanded before turning around and walking towards the sofa for a few hours of shut eye. "Remember, Kyuren. Wake me in a couple of hours."

Kyuren nodded. "Yeah, sure. But I think I'll take a crack at your neural interface. See if I can figure something out."

Sona thought about it for a moment before nodding. She wasn't shy about asking for help in this. They were a team after all. Perhaps he can figure something out. "All right, good luck." She yawned before lying down on the couch with Pip on her stomach, asleep.

"Sure." The raven haired teen whispered before going over to the consoles to get a closer look at Sona's work and maybe continue it while she rests.

Sitting on the chair, he cracked his fingers and began typing. "Let's see here..." He mumbled, going over what his partner had accomplished so far and try to work on that.

While he was trying to find a way to interface the suit's system to a person's brain, Sona slightly opened one eye and looked at Kyuren.

She watched him work and couldn't help the small smile coming along. The first time they met, he didn't exactly give her a very good impression of himself. Though that was eventually rectified.

In the weeks they had known each other, Sona had begun to feel comfortable with him. She didn't know why, but she did. Perhaps it was the familiarity between them.

Sona won't admit it out loud, but she was growing fond of the raven haired teen. He was more than a match for her in intelligence, and was quite nice to talk to.

And when they started this project, it just went further than that. Kyuren wasn't like some men out there that are sexist, thinking that women should be nothing more than housewives. The same could be said for most devils in that regard.

But he saw her as an equal and asked for her own thoughts and ideas. It was greatly appreciated by her to be able to contribute.

She didn't know what to feel about him, but a part of her wants to know him better. These past seven days, they had talked, yes, but only about the project.

The two of them hadn't taken the time to get to know each other more, and Sona wanted to know more about him. Not only because of the mystery of hiis overwhelming strength and power, but who is he exactly.

She wanted to know more about Kyuren Kaizer Avynzen.

Sona stopped her musing and once again looked at Kyuren who was running simulations. He had a contemplative look on as he analyzed his inputs before making some adjustments.

'Perhaps I could take the time to get to know him better.' She yawned tiredly. 'After all, it's what friends do.' And that was when she fell asleep.

The Sitri heiress felt something slightly rough, wet and warm brushing on her cheeks. It wasn't necessarily annoying, but it was enough to roust her from her sleep.

Slowly opening her eyes, blinking a couple of times to get the focus back, she saw that Pip was up in her face, licking her.

Giving out a sigh, Sona lifted her hand and scratched the kittens head. The Sitri heiress smiled when Pip purred and nuzzled into her touch.

Though it was a short time, she had grown fond of the Sphinx kitten. Even though Pip had a mean streak to her as evident when she scratched Issei almost to death. Looking back, it was pretty funny.

Deciding that it was time to wake up, Sona sat up on the sofa and yawned. That sleep did wonders for her, she felt reenergized.

After stretching her joints, she was about to stand when she noticed that there was a serving tray with a note on the lid. Curious, she reached over and took the note and read it.

'Didn't want to wake you. Enjoy your meal.' The note said before Sona lifted the lid and saw that it was her dinner. Sona briefly wondered who could've left the note here, until she figured it out.

'Kyuren. He must've set it here while I was sleeping.' Well, it was the only explanation since they were the only two here. The servants probably brought it down while he was working on…

"What time is it?" She asked herself, looking at the wall clock. She was surprised when it was already nine in the evening. 'I slept for five hours? I must've really tired myself out.' Sona said to herself before her thoughts returned to her partner.

Didn't she told him to wake her up in only a few hours? So why didn't he. She scowled a little and looked at where he was before her scowl was gone and her features softened.

There he was, his head down on the table with the screen still on and mug of coffee and an empty tray on either side. It looks like he fell asleep while he was trying to find a way for her idea to work.

Pip jumped off from the sofa and bounded over to her master and climbed on the table before lying beside Kyuren's head.

Going over there herself, Sona could hear his soft breath while her partner slept. She didn't really have the time to take a look at him more thoroughly, but she could honestly say that he was handsome.

Unknown to her, her hand was slowly reaching over to brush a stray lock of hair away from his face but just as it was going to touch him, Sona quickly pulled away her hand.

What just happened? Why did she try to touch him like that? These kinds of questions ran through her mind. Her heart was beating a mile a minute and she could feel it pounding in her chest.

True, Kyuren was a decent guy, but the Sitri heiress couldn't possibly like him that way. It wasn't impossible per say, but it was just too soon to feel anything for him. They were just partners in this.

Shaking her head to banish those thoughts away, Sona reached out and shook her partner shoulder gently. "Kyuren…Kyuren, wake up."

He stirred a little. "Mmm, six more hours…" He groaned out before returning to his slumber.

Sona could've sworn that she heard Pip hissing in laughter and while it was cute to hear, she had this bum to wake up. "Kyuren, it's time to wake up. Come on." She said more forcefully, shaking him more roughly.

That seemed to do the trick as Kyuren slowly opened his eyes and stared at her with drooping eyes. "Oh, it's just you." He sighed out, making Sona raise a brow before settling it back.

Sluggishly, Kyuren sat up on his chair and massaged his neck. "What time is it?" He groaned.

"Nine in the evening." Sona tried to bury her feelings from before for later. This was not the best time to act on her emotions.

Kyuren nodded and twisted his neck to get the kinks out while Sona looked over what he has done over to the holograms.

"Well, you've made very significant progress, but we still have a long way before it's a full interface." It was true, while Kyuren did speed things up, it would still take time for it to happen. How much time required was the problem.

The raven haired teen just gave her a smirk as Pip sat on the table, staring at the two. "You'll figure it out. You've made it this far before I had a crack at it."

Despite herself, Sona blushed at his compliment and those lingering feelings began acting up again. Though she quickly stamped them out. 'I can't let these feelings get the better of me. This is just harmless infatuation, it will pass.'

"Say, have you eaten yet?" Kyuren asked, turning around to see that she hadn't touched her food. "Well, that's not good. You should eat."

"I was. I was just checking up on you." After saying that, Sona immediately winced inwardly. "I mean, your progress." She added hastily.

Kyuren raised an eyebrow, but dropped it afterwards. Then the screens beeped, drawing their attention to it. Looking at it closely, Kyuren smiled when he found out what it was while Sona was curious.

"What is it?" She asked as Kyuren opened the mail.

"It's the core I had ordered for the suit's power source. It says here that it will be delivered by next week." Finally, they could start working on the reactor.

Sona nodded. All of their work would be for nothing if the suit wasn't powered up so this was good news indeed. And besides, she was curious at what this core is. "What kind of core is it? Is it harmful?" The last thing they needed was a health risk at this point.

Fortunately, her partner shook his head. "No, it's completely safe. I personally saw to it that it is."

Well, if he said it was safe then Sona will just have to trust him on that.

After a few minutes of going over of what they had already done, the two decided to call it a day...or night.

"I think's time for me to go home. Come along, Pip." He grabbed his precious kitten and placed her on top of his head before standing up and getting his jacket.

Sona bit her lower lip in hesitation. "...You know, I could arrange for a guest room for you. It is late out and the drive back will probably be an hour at best." She suggested.

She was just looking out for Kyuren as a friend, and as the Student Council president. Nothing more than that.

"Or you could just teleport me back to my suite." He gave his simple reply.

The Sitri heiress had to admit, she didn't thought of that. She could just easily teleport him there, that was the easiest and most convenient solution. And why did she feel...disappointed? "But what about your car?"

"Stays here until I come back here tomorrow. Classes are cancelled after all." Kyuren then stared at her with slightly squinted eyes. "Are you asking me to stay?"

Sona's eyes widened. "N-No!" She turned her head away from Kyuren's mismatched eyes. "I was just trying to be a generous host."

The raven haired boy stared at her for a few seconds more before sighing. "I appreciate the gesture, Ms. Shitori, but I wouldn't want to impose myself on your home."

"It wouldn't be." She shook her head. "I'm just suggesting that you could stay for the night if you want. Consider it as my thanks for helping with the neural interface." She nodded to the hologram rotating on the projectors.

"Meew." He heard Pip before she dropped down to his shoulder and jumped right onto Sona's lap and laid down.

Kyuren chuckled. "Looks like she wants to stay. She seems to like you." He motioned to his kitten, who was rubbing her head on Sona's stomach. "That or she just wants attention and pampering."

Sona let out a small smirk when she saw Pip seemingly glaring at her partner. That was funny and cute at the same time. "No, I think you have that covered. So, do you agree to stay for the night?"

After several seconds of thinking, Kyuren eventually nodded his head. "All right, fine. But I'm going to need some clothes. This one stinks...in fact, we both stink."

Despite taking slight offense to it, Sona sniffed at her own clothes before her nose scrunched up. He was right, they do stink.

"I'll have one of my servants fetch you some clothes." She said before they saved their work and shutting down the equipment for the day.

After eating her dinner and both of them taking showers - on separate stalls, mind you - they then headed off to bed, also in separate rooms

The next day, after doing their respective morning rituals and having breakfast, Kyuren and Sona were back at it down in their work station

Sona was continuing the progress she and Kyuren made with the neural interface as he was working on the next part of the suits, the gauntlets.

It was a good thing that classes were cancelled for today because of a board meeting with the school which required some teachers. So naturally, classes had to be cancelled this Wednesday.

And they could work at their own comfortable pace.

Kyuren was reviewing the schematics for the gauntlet and arm components on the holograms before moving on to fabricating it.

It should be easy enough for him. It was just like the thrusters after all.

Satisfied with the plans, the raven haired teen got to work in the fabrication.

The Sitri heiress was doing her own work as well with the neural connection. It was slow going at first, but she was confident that she could pull it off.

Simulations after simulations yielded results for her but there were still some obstacles before a working connection. It should be rectified shortly. Might take some time, but hopefully not much.

After a few hours of working, they decided to take a small break...or rather Kyuren did, he just dragged Sona along with him.

"You should relax more, Sona. You're at it with overworking again." He chuckled, sitting on the far side of the sofa with Sona on the other side and Pip playing with his hair.

"But this is no time for a break. I still have to analyze the results of my simulation and improve on that. And you still have to complete fabricating the arm components." She said with a sigh.

Kyuren chuckled. "We're only taking a short half hour break. It's not like we're abandoning this whole thing."

Sona huffed. "I know. It's just we could get more things done in that time."

"And we will. But it doesn't hurt to take a load off every once in a while." Kyuren then laid his head down on the head rest and closed his eyes.

The Sitri heiress was about to chastise him for sleeping, but held her tongue. They were on break after all, and it would just be rude to do it. With no other choice, she made herself comfortable.

She looked at him from the corner of her eyes and couldn't help but wonder. Was this the time to have a personal conversation with him? She wondered just who he was, not for his power, not for his strength, but just him.

Well, she wasn't going to get a chance like this so why not.

But she hesitated before she could open utter a word. She was asking who he was on a personal level. Though she had tried before, but Sona never really got to it.

"Kyuren?" There was no going back now.

"Yeah?" He returned. Well, at least he was awake.

Sona bit her lower lip. "Can I ask you a question?"

Kyuren made a smirk. "You already did." He chuckled and opened his eyes and stared at her with slight mirth until Pip pulled on his hair. "Ah! Pip, stop that!"

He grabbed Pip from the top of his head and laid her down on the ground and she wandered off. "Hehe, sorry about that." He chuckled before turning to his partner with a smirk. "What kind of questions though?"

"Personal ones." Kyuren's smirk dropped a little when she said that. And it didn't go unnoticed. "I'm not asking about your strength and how you got it. I'm asking to know more about you on a personal level."

The raven haired teen said nothing but opting to look at her that made Sona a little uncomfortable and fidgeted in her seat.

'I knew this was a bad idea.' She scolded herself. He was probably thinking that she was just saying that so he could tell her the secrets to his power.

She was about to apologize and drop the issue before Kyuren cut her off. "Okay." His response surprised her a little. "What do you want to know?"

"Are you sure?"

He nodded. "Yes, I trust you enough to reveal my plans for the armor." Kyuren motioned to hologram displaying a rotating image of the Iron Man suit. "What harm could telling you about me cause?"

Sona considered his words. No matter how you look at it, this was his masterpiece. Even though he told her that they were in this together, he did most of the work. He designed the armor from nothing.

It pained her to admit it, but she like she was just riding on his coat tails.

But he did trust her enough to let her join him. It was flattering that he wanted her to be apart of this; even more so when he said he wanted to include her own innovations.

After several seconds, Sona let out a little smile. "Then can you tell me about yourself?"

"Well, let me see..." Kyuren rubbed his chin in thought. "I was born in Norway to my mother and father, Eldora and Bernard Avynzen. My uncle...well, adopted uncle is Whilhem Larsen." As he said their names, Kyuren had a happy smile on.

"What were they like?"

His smile got even wider. "My mother is a very beautiful woman. Even by her age now, she's still very beautiful. Calm collected, and kind. She does charity work from time to time."

Sona joined in his amusement with a silent smile.

"Now, my father...is in some way, the opposite of my mother. While he was also calm and collected and was very dignified, he's also very strict when it comes to certain things. He isn't as giving as my mother, but he still cares."

"Sounds like your parents are interesting people." The Sitri heiress said and Kyuren let out a small amused laugh. "What about your adopted uncle?"

"Ah...Uncle Willy." He sighed in good nature. "A whimsical bundle of joy, he is. You know, there were times when I thought he was..." Kyuren twirled his finger beside his head and made coocoo sounds.

That made Sona giggle. "Come now, your uncle can't be that bad."

"Oh, you'd reconsider if you met him." Kyuren shook his head. "Yeah, that's my family for you."

"What about others? Don't you have cousins, or grandparent?" Sona asked. There wasn't any reason why he didn't have any ore family out there.

Kyuren shrugged. "I have a cousin from my mother's sister, her name's Mara. She's outgoing and adventurous, and a bit of a klutz. I lost count how many times we got into trouble because of her schemes."

Yeah, those times when she had convinced him to steal and eat the whole chocolate cake for a party. Let's just say their mothers got a little mad and punished them for eating the whole damn cake...but he regrets nothing.

"As for grandparents..." Kyuren briefly lost his smirk. "I never met them, actually." He looked at Sona who had a curious look on her face. "My mother said that her parents died in an accident long before I was born. Father didn't really know his own parents. He was orphaned at a very young age from what he told me."

"I'm sorry to hear that." Sona said but Kyuren waved her off.

"No, don't worry about it." He smiled at his partner. "Sure, it would've been nice to have met them, but I can't really think about it now."

Sona nodded. "Your family seems to be an interesting bunch." She said with a smirk. What with everything that she has heard, they truly were a little dysfunctional in a good way. It must've been one fun home life.

The raven haired teen laughed and nodded. "Yeah, they are."

"How did your parent's first met?"

Kyuren shrugged. "I don't know much, but Uncle Whilhem told me that they met by chance. After my mother's parents died, she became the heiress to their fortune. And my father was this big investor."

Sona hummed. "Hm, the old princess meets prince kind of way."

At hearing this, Kyuren snorted in agreement. "You got that right. My father almost didn't want to come until Whilhem somehow convinced him to. Like I said, I don't know much. But the two of them bumped into each other, it took some time but they eventually fell in love. Several years later, I came along." Kyuren huffed. "I guess you could say opposites attract in this one."

Sona let out a small giggle. "Yes." She then looked at him. "What's life like in Norway? I never actually visited it since it was the territory of the Norse Gods." It was true, not many other supernatural are permitted to enter other religions' domains.

Kyuren shrugged. "Well, it gets rather chilly there from time to time. But the cold never really bothered me anyway." To prove his point, he tapped the skin of his forearm. "Tough skin and all."

They spent the next hour talking about things. Just getting to know each other in a friendly conversation. And in that time, Sona had learned a great deal about her partner and his life back in Norway.

When she asked about his escapades there, he chuckled nervously and said that it was a story for another time. The Sitri heiress raised a curious brow, but decided to postpone that question.

"Looks like you had a good life in Norway." She commented, seemingly unaware that they were considerably closer to each other.

Kyuren nodded. "Yes, but it's not all sunshine there." He sighed.

"How so?"

"Well..." The raven haired teen rubbed the back of his neck. "I have some...pretty big shoes to fill. My parents are very important people and seeing as I'm their only child, expectations are high for me."

Sona could understand where her partner was coming from. While she was not an only child, her older sister was named the Devil King Leviathan. So she is permitted to claim leadership of the clan.

And so, Sona was named as the next head.

As is what anyone would expect for the next head, there is a lot of pressure for her to quickly accept the role. Her parents once tried to marry her to another pureblood devil, but fortunately, she was able to convince them that she would only marry someone she considered her equal.

But that was just a temporary solution. One day, she will have to marry someone. Sona just hoped that her parents didn't go behind her back on this one.

"But I guess that's enough for now." He stood up from the sofa and joined by the Sitri heiress. "It's been…" Looking at the clock, he whistled. "Wow, an hour."

"No matter, let's get back to work." She said, going back to her serious attitude and went back to the computers but not before turning back to Kyuren with a small smile. "But…thank you…for talking to me."

The raven haired teen returned her smile. "Your welcome."

AN:

Another chapter…well, more like a filler chapter showing a little bit of bonding between Sona and Kyuren as they build the Iron Man armor.

Also, if you didn't know, I issued a challenge for another story that I'm sure is going to be good. It's a Familiar of Zero story, but instead of Saito, or any other hero for that matter, it's going to be a villain.

BLACK ADAM.

Yes, the DC supervillain and long-time enemy of Shazam or Captain Marvel.

Conditions:

- Black Adam should not be portrayed primarily as a villain. More like an anti-villain.

- He can be summoned by anyone but definitely not Louise. With her attitude, Adam would not hesitate to kill her. Really shortens the story. Recommendations are Tabitha, Henrietta, and Tiffania but you can choose any other just not Louise.

- Pairings are optional.

- Any version of Adam is accepted, but his appearance will be the New 52 version. (Way more badass imo.)

- And lastly, he must be summoned before the modern era. Meaning that he was summoned in ancient times very early in his career as Black Adam. Perhaps as a teenager.

That is all. Other than the conditions I have given; you have free reign over the plot and the story. Good luck.
