It Started With Devils & Artefacts

With the sound of a whistle and a soft thunderclap, the upper portion of a mannequin disintegrated. Within seconds, several more received the same treatment.

Marcus lowered Castor and changed his stance, he pulled his right foot back and put forward his left, slightly standing sideways he lifted Pollux.

Pulling the trigger, a much larger white circle appeared at the end of the barrel, moments later golf sized balls of the Power of Destruction starter raining out from it and rushing into the partially destroyed mannequins.

The barrage of energy destroyed the remains and made multiple holes in the wall.

"Test number five is a success. Castor and Pollux are working perfectly, there are no errors in the Aurora targeting system. The revolver system switch is around 1 to 2 seconds. Charging time for maximum output is around 5 seconds." As Marcus said that, he could see on his Visor that his voice had been recorded and could see that Aurora was writing it all down like a log, under test number 5.

After he finished the log he sighed and holstered both of his guns to the sides of his thighs. He already had some simple holsters ready. Honestly, he was thinking of making a maintenance version of the holsters, but then he remembered that it was not needed at the moment.

Marcus lifted his glasses and turned around looking at his newest addition to the fold.

The silver-haired maid has been staring at him for the past 5 test runs, right after he had finished the Mark IV of Castor and Pollux.

With the Aurora systems, he is now a very sharpshooter.

Nonetheless, he still has some things to do before he can go to Kuoh. A few more gadgets to make.

"May I know what's with the staring?" He asked with a sigh. He got used to Serafall's staring which was quite comforting, since she  always had a curious and fond look. This however was different.

"Your power… you based it on the fact that my family are servants to the Lucifer. You made a simple servitude into power. Which crystallised into some sort of bond of servitude.

Now… I have an instinct to serve you. It is like trying to fight a water current. I could only resist it for several weeks before it fully consumed me." She explained in a single breath. Her gaze never left him.

"So. What you want to say is that, you want to serve me?" He couldn't help but ask her with raised eyebrows. He never could have predicted that it would have developed into an instinct to serve. There was no calculation that she would have developed it.

Which means it is just her feelings mixed into it.

'In other words, she has a fetish to serve…' 

Marcus realised that after remembering how she was still a maid even though she was the wife of Lucifer, both in the anime and light novel version.

"Correct… while serving my King is an order from you, it doesn't give me true satisfaction… That is why I am here." She explained plainly. Through his modified version of Ars Goetia, he could tell that she got over her dislike for him.

Which was surprisingly fast. Even faster than Serafall. Now, all that was left was her need to serve…

'Her servitude consumed her dislike… this woman truly had that deep of a desire to be a maid?'

The teenage inventor quickly realised, that was most likely how those extra devil families were created, with absolute servitude in mind.

"I see… so you want to be my maid in all sense and form?" He asked her, starting to walk towards her. 

Grayfia simply nodded at him with a bow, realising full well what kind of hole she was getting herself into.

"I know quite well what all of it implies and yes, I have no desire to resist it anymore." The silver-haired maid said plainly.

Marcus simply nodded. He won't deny that having such an utterly beautiful woman with a body that breaks the laws of the world is quite the turn on.

The teenage inventor removed his gloves before lifting his right hand and gently stroking her cheek. She didn't say anything or react in any way.

"Since you are so insistent. I will have to make you my maid in every sense." He said while looking directly into her eyes, this time she slightly blushed. She felt goosebumps going through her whole body. Grayfia didn't know if it was a natural response or a response amplified by her binding.

Nonetheless, she was getting excited, excited to...serve!

~~~~~~(R18 incoming, skip to 'Underworld' if you don't want to read)~~~~~~

Without warning, Marcus pulled the silver-haired beauty for a kiss, her eyes widened. It was something she was not expecting and her magic didn't react to it at all. As normally she would have frozen anyone who tried to do that to her.

The teen wrapped his hands around her waist before going lower towards her firm rear gripping it through her maid's uniform.

While his lips were exploring the insides of her mouth; playing around with her tongue. And before long the maid was slightly moaning as she started losing herself to the pleasure.

She never could have thought that the feeling would be this intense. It was like experiencing the greatest of joys while being kissed by her Master!

Soon after, she wrapped her hands around him and started kissing back. Her eyes had already turned glassy.

The kissing intensified as she started rubbing herself onto him. Marcus already knew that she was turned on and wants to take this to the next level. So he lifted her quite casually and took her to the main area where the couches are.

He then laid her on her back and positioned himself on top of her.

Once there he started taking off her clothes, seconds later he saw her in a pair of sexy white panties, bra, and tight long white stockings.

"Quite sexy… can't wait to dress you up. Grayfia~~~" He said hotly into her ear as he started kissing her neck before going lower towards her towering breasts.

"Ahhh~~~ if that's what you want Master~~~" The silver-haired maid said softly as she touched herself for a bit. She is feeling like she was on fire.

The teen just smiled while starting to remove her bra and getting his first look at her incredible breasts. The moment he started to play with them, Grayfia moaned quite loudly. There was a shocked look on her face before being replaced by a horny look.

"Yes~~~touch me more...play with them~~~" She asked in a sexy tone as she looked hotly at him.

All she got from him was a grin as he continued his assault on her mountain peaks. Before long she was breathing haggardly and sweat was rolling down her forehead.

The beautiful maid's sensitivity was quite high and, by this point, Marcus could not take this anymore and wanted to move to the main dish. 

So his hand went down and removed her drenched panties and looked at her wet pussy entrance. His fingers brushed through it and Grayfia mewed from the touch.

"Hahh~~~ let's do it~~~ please... claim me~~~" She hotly begged him. She needs to seal the deal so that she could be his proper maid!

After hearing such a begging tone Marcus removed his pants and positioned his raging boner at her wet cave.

The silver-haired maid softly moaned when she felt the tip of his rod at her entrance.

"Yes~~~" She said as she started moving her hips, she wanted that thing in her special place, as soon as possible!

Without wasting much time he started pushing inside, she was so wet that there was no need for any foreplay. Before long he was already pumping into her without any restrain.

"Hhmmn~~~"

"Nnhhnn~~~"

"Ohhh~~~"

"That's it!!! More! Ravage me~~~" Grayfia howled from top of her lungs when she felt her first orgasm. She felt like her mind just went blank. The feeling she was experiencing was off the charts.

To experience more the beauty coiled her legs around his waist while Marcus used that movement to lean forward and claim her lips once more. The silver-haired maid answered back with the same amount of heat as she wrapped her hand around his neck and started moving her hips according to his thrusts.

Soon enough a lewd clapping sound started spreading through the workshop.

It only accelerated before a loud muffled moan spread throughout the place.

The beautiful maid just experienced her first creampie from her Master.

…

…

…

"And now you are my proper maid" The teen said to the silver-haired beauty who was sitting on her master lap facing away from him. Her legs are spread. His rod was still inside of her as he was still pumping into her while whispering into her ear.

"As long as I can serve you properly~~~ I don't care…" She said with a glassy look as she softly continued to moan to his thrust.

His only response to that was a squeeze on one of her nipples.

"Ahhh~~~"

~~~~~~Underworld~~~~~~

Both Rias Gremory and Sona Sitri were fiddling nervously as they were just called by Satan Leviathan herself to come to see her.

The younger Sitri has been slightly weirded out by her sister's behaviour for the past several years. Her older sister out of nowhere stopped her whole Magic girl act thing, she had been doing it since the 1990s. So it was very weird that her sister suddenly stopped.

And each time Sona would ask about her older sister's change she would hear only one answer…  that it was utterly silly and she got tired of it.

While she sighed with relief since it was embarrassing, she knew that there was something more to it. 

"Do you know why we suddenly got requested to meet your older sister?" Sona's best friend asked with a slight bit of weariness. 

Strangely, they got this meeting just around the time that they had to move to the Human world!

"No, I am just as clueless as you are." Sona said that while shaking her head.

"I see… this is just weird. I heard a rumour that Satan Leviathan has been spending a lot of time in the human world." Rias said, a bit jealous.

"I have heard the same. And weirdly enough my sister has said nothing about her trips there." Sona said while fixing glasses, she looked quite sharp thinking about the reasons.

"That's because I can't tell you anything about it." 

Both girls heard Serafall's voice as the Leviathan circle appeared and with a burst of dark blue one of the Satans appeared dressed in a blue dress and high heels. She looked like she was about to go into a ball.

Both of the younger girls slightly gulped down seeing a serious looking Satan Leviathan.

"You can't?"

"I can't because I am under a devil contract." She said plainly as she walked over and took her seat opposite to the pair.

She got comfortable while the pair got very uncomfortable. They were seeing a very different Serafall to the one they used to see.

"I see… might we know what this meeting is all about?" Sona asked professionally but internally she hoped that it's not something bad like they were not going to the human world or something like that.

"The reason for this meeting is very simple; both of you are going to the human world, while there is nothing bad about it, Kuoh doesn't have any proper protection or surveillance installed to help the both of you control the supernatural flow there.

Since both of you are high profile peoples, there will be many who will wish to mess or simply to see how good the siblings of the Satans are." Serafall explained plainly.

"While I know both of you are talented there are many beings who are stronger than both of you."

"Are you going to send someone to...babysit us?" Sona asked in a slightly pissed off tone.

"No. We already discussed that. There won't be any bodyguards. But this doesn't mean we can't have a powerful surveillance system installed in the city that will assist the two of you, in case a powerful being appears in the city both of you will be able to notify the Underworld in time for help to arrive." 

As Serafall explained that, the pair looked at each other. From the looks they give each other they were planning not to notify anything. And the Satan Leviathan knows that already. That's why she likes what Marcus has planned.

"That's why I used the person, which I am under contract with, to assist us." As Serafall explained, she got extremely serious.

"Now listen up. It took me years to get his assistance in any form, so you two won't be destroying the trust I have built with him." 

"Uhh… is he a human? Assuming this is the reason why you are going to the human world?" 

"Indeed he is a one in millenia genius inventor. He summoned me as his devil and I formed a contract with him." Serafall said the very barebones needed for this.

"...He summoned a... Satan?" Sona asked with wide eyes. Rias was also surprised. They both know that Satans are summonable, but only the leaders of nations or extremely influential people can do that. Because the prices for it are very high. Since they don't take in souls anymore, it's usually in the form of money or items.

So, summoning them is practically impossible because the summoner has to intrigue Satan in the first place with something of worth.

"Indeed. By this point, his inventions are at least advanced by 40 years in human standards."

This made them even more shocked while Rias for some reason was getting a very anime-style vibe from this human.

"That's why when I asked for his assistance in building a surveillance system for Kuoh and he only agreed under a form of contract. Meaning that, the both of you will be under a devil contract and will be following his request to test the surveillance system which will be deployed in Kouh."

"...I see… this is more than acceptable then. Since we will be getting a reputation by having a contract formed with someone who has a contract with Satan." Sona said with a small smile. This was good for her.

Rias nodded as well. She was curious about this human. But, since it's under the care of a Satan she can't ask such an individual to join her peerage.

"Yes. Now remember…" Serafall leaned forward and her eyes were glowing and her magic presence manifested around the whole room. Both Sona and Rias gulped down nervously.

"I am sticking out my neck for this. We can't lose someone who is at a level that's even above the likes of Da Vinci. He has already created a pantheon level worthy security system in his hometown.

If we lose him and he joins Fallen Angels or worse, that bitch's Gabriel side! It won't be pretty." 

Both of them paled hearing that they quickly responded with a nod.

"We will treat him as a worthy guest! Don't worry sister." Sona quickly added. Now she knows what is going on. Her sister has a thing for him and she demands 'proper' behaviour from her family.

The younger Sitri has no idea how this human did all that. But one thing is for sure he is very good. So good that he made her sister fall head over heels for him.

Now she truly wants to meet him. Possibly her future brother-in-law?

Well… there are only a few days left till that day.

"We will see… I will be there as well."

"Hmm? Don't you have work?" Sona asked with disbelief.

*Snort*

"One of his inventions cut my working time by 80%. I finish most of my work before midday." Serafall quite smugly said that.

"Oh… now I remembered! Brother was bragging about something similar as well. But he is quite tight-lipped about it too!" Rias remembered her big brother spending more time at home now than ever and he is quite smug about it as well…

"Yes, client confidentiality. Which you two will be signing. This is only going to last until he is ready to reveal himself. So you two only need to keep quiet for a few years. After that, you can discuss this with anyone you like." Serafall said as she snapped her fingers and she summoned two pieces of documents.

Both Rias and Sona quickly picked them up and started reading. It was in the basic form. They have seen this in devil school. And know what it entails.

Without wasting their time both signed them and then the document disappeared.

"You may reveal the information to your peerage under conditions that they can't talk about this." Serafall with a serious tone explained.

"I understand/ Thank you."

"Good, then it settles it." The Leviathan was satisfied, for now. She will be watching though.

"Umm… so, Sister… is he… well… you know…" Sona fiddled with her dress for a second.

She is not used to the serious and, well… Satan-like version of Serafall…

"Know what?" The older Sitri moved her head aside for a second, trying to see what her little sister meant by that.

"You like... him?" Sona asked with slightly flushed cheeks.

Serafall slightly giggled for a second.

"You didn't hear this from me. But, yes… It would appear that I have things for men who can build wonders from scraps they find in a garage." She started talking animatedly before getting serious once more.

"That's why you two will be on your best behaviour. I was working for years to build trust with him. And I don't want to lose it now."

"Sister… won't it be easier for you to just say… that you like him?" Sona tried to reason with that.

*Snort*

"I was summoned by him because I am Satan Leviathan. I was summoned to help him to set up pipes for his workshop because I am Leviathan and an expert in water manipulation." She said while rolling her eyes.

"I told you, didn't I? He has already installed a pantheon-worthy security system in his home town being the same age as you two."

""WHAT!!!""

"He is the same age as us?/ He summoned you for what?" Both of them were shell shocked to hear that.

"This means that I was qualified enough to be summoned." 

"But… you are a Satan sister!" Sona pointed out with disbelief.

"And he single handedly, with a blob of clay built a surveillance system which will last as long as Earth rotating around the sun. What of it?" Serafall said with an eye roll. Which made both of the younger girls shut their mouths before they could say anything.

"Creating things is much harder than destroying them. While my power is impressive he has already found ways to beat me."

"...He did?" Sona squeaked funnily.

*Sigh*

" I already told you that he is a once in millennia genius. Do you think I will fall in love with someone average?" Serafall was getting tired of everyone looking down on her Marcus like that. Sirzechs did… well not anymore… after seeing Signer he became a fan… and now her sister still doesn't get the message when she said Pantheon level security. It means security is good enough for a pantheon!

"No...I mean… he is a human…"

"And what is that supposed to mean? He can't be smart?" Serafall said with raised eyebrows. Is her sister getting biased?

"How… does smart have to do anything with strength?" Rias asked from the side. Earning a couple of stares from the Sitri siblings...

Sona just groaned. It seems she was too short-sighted…

"Easy enough… for example, he could build a gun which could kill an Ultimate Class Devil." Serafall gave them an example with a smile.

"That's simply impossible," Rias said while shaking her head.

"You want to bet on it?" The Satan Leviathan said with a smirk.

The redhead girl quickly shook her head. No, she won't be betting on this while Sona started to understand the scale of things.

If her sister is willing to bet then this human indeed is capable of doing such things. Then this is very big indeed. This means that he is smart to an absurd level. Now the younger Sitri indeed wants to meet him.

"Wise choice. And since we are discussing him like this I expect both of you to keep this to your peerage and nothing more. You can tell them that if they fail they will have to deal with me."

"I understand, sister. There is no need for you to threaten me so many times…" Sona said with a sigh.

"I am only making sure you two understand." 

""We do…"" 

~~~~~~~Marcus~~~~~~

With a burst of light, I appeared in a Victorian mansion. This was my first time travelling through a teleportation circle.

The experience was quite… seamless… one moment I was in my garage and next, I was in a large room.

The difference though was the timezone. When I left my garage it was nearly midnight but, when I arrived here it was morning.

"This is the Sitri estate in Kuoh. Follow me, let me show you where they are." Serafall motioned for me to follow her as we started walking towards a pair of double doors.

Without wasting any time she opened them and entered inside while I followed after her.

The first thing I saw were four females waiting for me.

The one standing out the most was the redhead. For the simple reason that she was a pure redhead.

I have never seen someone with pure crimson hair like that before. A ginger? Yes, I saw plenty of those. But a redhead like that? Nope. Well, I am in what is considered an 'anime' world, not that I saw any black lines on my body or anything like that…

I am pretty sure some world governing laws are much weaker, my technology is a proof of that. I am having a much easier time with them. Either that or, my genius simply went up to a completely different plateau, so much so that I find making things much easier.

Back to the matter at hand. Apart from that beautiful hair, she was a carbon copy of Venelana. A Younger and much more naive version with longer hair.

Next was the black-haired girl next to Rias Gremory. Her Queen Akeno Himejima… a girl who is the daughter of Baraqiel. One of the top dogs of Grigori and Lightning of the God… a girl who doesn't want to use her inborn powers because she doesn't like her father…

My only comment to that is… she's stupid and wasteful…

Next on the other side of Rias, is Serafall's little sister Sona Sitri. I can see some similarities between them. Where Serafall can easily pass as a socialite, Sona can pass as a librarian. The sharp glasses only add to that. The only difference is that she has striking purple eyes.

As for the last, it's Sona's Queen who is quite similar to Sona with sharp glasses, a girl from a prestigious clan of exorcists. With a Sacred Gear no less. Just like Rias Queen this one had similar treatment because of how different she was.

All I can say about this, it is basically like saying: one's trash is another's treasure.

'Now that I think about it, this place has an enormous concentration of Sacred Gears. I have not even found one in my hometown. Yet this small town has more than a few running around.

Well, it's either something to do with the amount of magic in the air or just some main cast, main city bullshit.' Internally I sighed.

'Since I am here I might as well find out all those little secrets.' Smiling to myself I walked forward toward the group of girls.

They all looked nervous, like they were standing on extremely thin ice. It seems Serafall words have cut them very, very deep.

~~~

The small group of devil ladies waited with a nervous look as they knew the current Leviathan would soon bring over the genius inventor Marcus Goldman.

The moment they learned his name they tried to find anything they could about him.

All they got was classified information under Satan Leviathan's seal. So they tried to do the same in the human world…

It was the same… they could not find anything for the simple reason that he lives on the other side of the globe.

In other words, there was nothing on him. even if it was, it's under Serafall's watchful eye.

They didn't even know what he looked like!

When the doors opened their backs strengthened and they tried to look as professional as they could.

The moment Sona and Rias saw him they were having a hard time believing that he was the same age as they! He looked far too mature!

Broad shoulders, short black hair, striking brown eyes, he looked as if he knew what he was doing, but the most striking thing about him was...

'His magic level is even bigger than ours!!!' Sona thought with a little bit of sweat rolling down her forehead, her Queen was the same as she fixed her glasses for a second. She has never met someone their age with this much magic!

'Is he truly a human?' Rias tried to comprehend how this guy has this much magic!

While Akeno wanted to lick her lips after seeing him… 

"...Marcus here they are. The girl with sharp-looking glasses similar to me is Sona… the one to her right is her Queen Tsubaki Shinra. And to my sister's left is Rias Gremory and her Queen Akeno Himejima." Serafall introduced them all in a single breath. This made the girls slightly out of the element, they expected a proper introduction…

"Well, ladies, you are responsible for the Kuoh from now on, correct?" He asked with a harmless smile.

"Y-Yes. Both Rias and myself will be sharing the burden. I will be watching over the city during the daytime while she will do it at nighttime." Sona quickly explained simply and as professionally as possible.

"I see… simple enough. Have you two decided where you want the core of the barrier system to be placed?" He asked them as he instantly moved towards the main dish.

Both Devil Heiresses did not expect for him to move directly at that! 

Now they know why Serafall did such a simple introduction! He simply wants to get this over with...

"Well… I suppose  since Kuoh Academy is our seat of power here, so maybe the school basement?" Sona answered after thinking for a bit. She then looked for Rias who nodded back at her.

"Hmm… very well." He nodded at them and then looked back at Serafall.

"Sera, where is the exact location of the building compared to the city?" He asked her.

Both Sona and Rias looked with a little bit of wonder and awe hearing how he calls Leviathan by her nickname!

"The Academy is located more to the north of the city centre. I can assume you are going to need to adjust the deployment? Like back in your town?" The black-haired Satan answered after thinking about it for a bit.

"If it's true. Then yes, I will need to adjust the disperse of magic from the core. Nonetheless, I need to double-check that on the map.

Hmm… this would be a good moment to add map tracking as well." Marcus said the last part more to himself than to the rest of the group.

"Right. Then let's go to this Academy of yours, ladies." He said after turning back to the group.

"...Now?" Sona asked with disbelief, all she got back was Serafall's stare. The younger Sitri gulped down.

"S-Sure… we can teleport there before anyone comes for classes …" The Sitri Heiress said while fixing her glasses and hiding her sweaty forehead.

This was way too fast for her!

While Marcus simply nodded at her.

"Very well. Sera will transport us there."

"As you wish." 

Without wasting much time, a large Leviathan circle appeared underneath them before teleporting them into school grounds.

"Well… Show the way." He motioned to Sona.

"O-Okay…" 

~~~

As expected from the posh Pillar houses. The school… I mean the academy was beautiful and very… European, I don't know what they are planning but this was ridiculous. If you are moving in, at least try to adapt to their culture.

At least they have the whole shoes policy in place, I will be able to enjoy some of the cultural things. Though, I don't think I will be coming here often unless of course there is some...loot...I mean some profitable enemies to fight…

Nonetheless, the walk was not silent as Serafall kept telling me things about the Academy. Trying to rope me in and trying to transfer me here. Her little sister quickly picked it up and started chipping in from time to time.

My reaction to all that was an eye roll. Serafall saw that and showed her tongue at me. All she got was another eye roll.

Very cute...especially when it comes from one of the top leaders of a supernatural faction. Who is acting all cute and cuddly with me. It was even better when Rias and the other two saw our little exchange. They were quite shocked…

"This is the basement. We haven't touched anything here." Sona spoke professionally as she showed the large empty area.

"Nice, this will do…" I said while looking around. It was built from strong concrete. The walls were done through a combination of magic and regular means.

"I see… so this is how you guys build. To keep things from disappearing you use magic to create the reaction which… in turn, allows the result to stay. While this is quite energy-consuming it still allows you to keep things after the demonic energy runs out." I said while inspecting the walls.

The younger devils looked at me with slight disbelief while Serafall just smiled. 

"Not fair… I'm still trying to figure out your transmutation circle!" The Leviathan said with a pouty look.

"It's not my problem that you prefer to stare at me when I work," I said with another eye roll.

This time she huffed and looked away. 

"You figured that out from touching the wall?" Sona asked while trying to keep her glasses from falling off her nose.

"Indeed. Quite easy, the residue is still there. While very faint, I can still feel demonic energy in the creation of this." I explained while pointing my finger at the wall as I looked around for more.

"B-But…"
