3. Lucifer Maou-sama

Disclaimer: I don't own Hataraku Maou-sama nor High school DxD

Chapter three is out baby!

Ah! Forgot to tell the timeline they're at. They're literally when the series of DxD start. (A little bit before Issei's date with Yuuma/Raynare)

It's time to our dimension travelers to learn about the cruel reality with demons in the DxD universe.

Answering some reviews:

To CyberIona: Yes, I'll keep making humorous parts to keep up the mood, but there will be times when they're going to be serious. And the other question, if you mean that if Maou is going to be working at a MgRonalds than that would be a no, he is going to be a student at Kuoh, the ones that'll be working are going to be Alsiel/Ashiya and Adramelech/Adram because they need to pay their rent.

ENDDRAGON369: Sorry, I haven't watched Fate Stay Night yet. But due to your comment I'm gonna start watching it so that maybe later fics are or have content about it. In the meantime, I'm going to keep the powers as they are in their respective series… okay I might have some changes but for some reason is called fanfiction.

To LL: while making this chapter and answering your question I rewatched episode 1 of Hataraku Maou-sama about three times and it said that on Earth there was no magic, but as long the concept existed they could still have access to it, and another thing was that Maou said "It's hard to keep my magic from leaking out", in other words, saying that magic would leave their bodies any moment if they weren't careful, since the DxD universe is similar to the real world (talking about geography and technology) it's hard, but not much for them to keep their magic in check. So when they got out of the portal they weren't aware of that, so some magic leaked out.

Just before you start reading I have to announce that Maou is not that attached to this world or the humans.

Well the story will start in 3… 2… 1

"Talking"

'Thinking'

"Dark/Deep voice and spells"

*Sound or movements*

Last Chapter

"They're actually coexisting with the humans"

"Who?" 'Seriously guys who else?!" Maou yelled in his head.

"The demons" *Blink* *stare* *blink again*

"Eeeeehhhh?!"

Chapter 3. Lucifer Maou-sama to you!

Two days after enrolling at Kuoh

Classes went by as normal, the students would be whispering instead of paying attention, some others would be looking out the window and a little group would be playing with their mobiles while the teacher wrote some notes in the chalkboard.

But a certain third year classroom wasn't.

Room 3-A was more silent than a ghost town. Ashiya was on the board while explaining some advanced chemistry to the classroom while all the students wrote down notes in their notebooks.

'Damn that Ashiya he's even making me write down this stuff' thought Sadao Maou aka Satan Jacob, with a thick mark on his head 'His first impression was awesome, but why do I have to do this too?' thought Maou with tears in his eyes.

Flashback

After the introductions. Ashiya's POV

'Their introduction was flawless, they'll have no problem blending in with the classroom' I thought with a happy expression before focusing again in the demons my lord mentioned earlier 'So the red-haired beauty, the girl with a ponytail and he said he felt a third one in this classroom.'

I started inspecting the classroom trying to find anyone that looked suspicious until I found a girl with glasses staring right back at me 'She looks suspicious, let's see what's her name?' I took out the student list they gave me 'First row… third seat… Shitori Sona uh?'

I then looked at the name of the other two girls 'Last row… last seat… Rias Gremory and third row…second seat… Himejima Akeno… my lord, are you sure they're demons?'

"Sadao-san, you take a sit next to Gremory-san, Urushihara-san you sit behind Himejima-san and Mahl-san please take a sit next to Shitori-san" I told the three who looked at me for a moment.

"Hai, sensei" they said and started going to their respective seats, but I noticed that Lucifer had forced his smile 'Lucifer doesn't like the idea of me commanding him… I'm going to enjoy teasing him'

After they sat down I started writing some math problems in chalkboard, but I stopped myself when I heard whispering behind me. I clenched my fists and gritted my teeth.

'These disrespectful bastards' I stopped what I was writing and headed towards the group of students that were talking. Everyone in the classroom focused their eyes on me, I couldn't care less 'Let this be a lesson to remember'

They were three boys with heads down and hands covering their mouths I soon stopped myself behind one of the boys. The two in front quickly noticed me and their face turned into one of utter fear 'I see… I can fuel my magic being a teacher, very clever Maou-sama'

"Really? Another teacher? and out of nowhere I bet he doesn't even know shit…" 'Oohh, this kid is going to regretted' "Hey, why did you suddenly stopped talking?" the teen was confused by the faces of his classmates.

"Sooo, you think I don't know, what was the word you used… 'shit'?" I used some magic to make my voice more sinister at the end 'I'm not going to let this kid insult me like that, I spent the whole night learning about subjects of this world'

I could tell I almost gave the boy a heart attack by the way he jumped out of his seat. He slowly turned around to face me, his face was pale and his eyes wide.

"I would like you to accompany me" I walked out of the room behind the student. His whole body was shaking.

Rias's POV

'What was that? I could tell his voice got a darker tone out of the sudden' I looked at the whole classroom. They were completely silent, that wasn't normal. Usually they always talked when the teacher was gone, but almost all of them were shocked at what just happened before our eyes.

I looked at the three transfer students. They were grinning madly. 'Why are they grinning? Didn't they noticed the darker tone used by the sensei?!' I was so confused right now.

I turned to see Akeno, she was looking back at me as if asking me 'What happened?' I just shook my head.

"Alsiel sure knows how to make a first impression…" it was barely audible, but I heard it.

I turned my head to see the new student 'what was his name? Sadao… Maou?! Why is he named like a demon king?!'

I then realized something. He called Ashiya-sensei "Alsiel" 'Who are they?!'

He turned to look at me giving me a warm smile, I couldn't help but blush a little.

Soon he diverted his gaze and looked at the doorway that suddenly opened.

Sona's POV

As soon as the doorway opened the student that went with Ashiya-sensei entered the room followed by sensei. I couldn't help but feel sorry for the student, he was shaking his eyes were still wide open but his gaze was looking at nothingness.

I then heard a chuckle. I quickly turned towards the sound and found Akohda-san trying to hold back his laughter. I quickly looked over to Lucifer-san who was also holding his laugh, and then at Maou who was muttering something, which made Rias look at him with a surprised look.

'Who are this people? I didn't receive word from the principal about their transference, was he bought… no that's impossible he's loyal to my family' I am so confused right now.

'No, I need to stay calm' even if I thought that I was a little scared of them, who wouldn't? they were a mystery.

'And just the night before I had trouble with the mysterious energy…' realization hit me like a truck, my eyes widened and turned my head violently looking at the three 'could they be…?'

"Shitori-san" my thoughts were interrupted by the sensei who was calling for me.

"Hai!" I responded, even if he was unknown to me he was still my sensei.

"You're the president of the student council, right?" I looked up at him and my heart stopped for a bit, he was smiling warmly at me.

'STOP! Don't get impure thoughts you're a role model in this school!' I yelled at myself in my head "Yes, yes I am, why do you ask sensei?"

"Tell me, as the president of the student council, is it okay for a student to talk while the sensei is giving class?" his tone was calm almost as if this was nothing to him.

"No, sensei, it is something inappropriate from the student" I said seeing where this was going.

"Class, from now on I'll not tolerate any insubordination, if you're going to talk make sure you finish your work first and ask permission for it. If I hear you talking, you'll be given a test that will go to your grades. There will be NO exceptions" he said with emphasis in the word 'no'.

'What is this aura he is emitting, it feels almost like… a general putting in line his subordinates' I smiled a little.

This was the kind of teachers this school needed.

End of Flashback

Maou was walking down the halls with Lucifer and Akohda at his sides. They were heading to the back of the school towards PE class with Adram and were more than happy.

They had secretly been gaining magic from the negative emotions and thoughts of the students in the school. Jealousy, fear, stress, greed they were all in the school.

A day ago, in the bathroom, Maou had changed to his original form without noticing. When he got out of the bathroom everyone started to run away from him.

It was really troubling for him, he didn't want to blow his cover yet and had to erase everyone memories, it was a miracle he wasn't seen by members of the student council or the ORC, because then he would've had trouble.

When he arrived home, he found out that the same happened to all his generals.

Adram was giving class when suddenly all his clothes shattered, the students started to run away from him. He also was confused until saw that his height increased immensely 'Crap' was the only thing he thought.

Lucifer was heading to the teacher's room along with Ashiya for sleeping in class when he felt something familiar in his back. "MY WINGS!" he had yelled in excitement before being grabbed by a fully transformed Alsiel and teleported away.

Akohda was a different story. When he sensed his powers back he was about to go in a rampage to kill all the students that always stared at him, but before he could do anything he was teleported away by Alsiel who for some reason was grabbing Lucifer with him.

"Uf, I didn't want to blow up my cover, I was saving that for today" said Maou to his friends/generals.

"Are you sure is wise Maou?" asked Lucifer who was okay with being under cover.

"Of course, during this two days I was able to tell who are demons in the school, you guys might have noticed when you got your magic back" said Maou looking back at the two.

"I did, it appears that the whole student council are demons" pointed Akohda who just keep sending glares at all the people he got close to.

"Yes, I also noticed that the other 'Prince' of Kuoh, Yuuto Kiba, is a demon, along with the pet of the school Koneko Toujo" stated Lucifer as they went down the stairs.

"Yes, and to piece everything together we have Akeno Himejima, who I could feel was part fallen angel, and Rias Gremory, who both hang out with Kiba and Koneko in the old building saying is club activity" finished Maou who now was outside looking at the poor students that had PE before them.

"But I felt something strange Maou" muttered Akohda so that no one could eavesdrop.

"What is it?" asked Maou since he really never sensed anything else.

"Is one the guys from the perverted trio, Issei Hyoudou, he has something inside him, but is not a demon, and angel or fallen angel" reported Akohda.

At this Maou brought his hand to his chin and started to think 'A threat? No, it's impossible, maybe something we've never encountered, it could mean trouble' "Lucifer" Maou called.

"Hai!" quickly responded Lucifer.

"Keep an eye on Hyoudou, we can't have him dying, he might be useful in the future, plus it could be bad to have him as an enemy" ordered Maou while absorbing some magic from the students that passed by him.

'Adram surely makes them do some impossible exercises' thought the three of them. As they reached the field.

"WELCOME CLASS 3-A" 'And he literally enjoys it' they thought with a sweat drop.

"Sensei" a random student raised his hand "What is it that make's all other students so tired at the end of your class"

At the question Adram just laughed, which startled some students "Glad you asked young one"

"We'll be doing: a four-kilometer run, followed by two series of 50 squats, 100 sit-ups and two series of 50 push-ups with someone in your back! And when you finish you get free time!" said Adram very excited.

It wasn't a full second since he finished talking and the complaints started to appear.

"EEEEEHHH?!" "Sensei that's impossible" "No human being could do that in the whole hour we have!" "Yeah, change the routine!"

Adram grew a vein on his head "If you keep complaining you'll never finish! Look over there Sadao-san, Urushihara-san, and Mahl-san already started" everyone's jaw hit the ground when they turned around to see the three mentioned earlier, running at incredible speeds.

"I won!" exclaimed Lucifer who started to jump with his fist raised.

"Not fair Lucifer, you started beforehand!" yelled Akohda trying to punch him.

"Let him be Akohda let's see who wins in the series!" said Maou who positioned himself in a squat pose, soon Akohda and Lucifer got ready.

"Ready… set… Go!" like if it was nothing, they started doing squads with such speed they started picking up some dust from the ground.

"Hundred!" exclaimed Akohda this time.

"Dammit, I almost had it" muttered Lucifer "next is sit-ups"

"Hundred!" exclaimed Maou who picked himself up off the ground.

"Eeehh?! We didn't even say 'go!'" complained Lucifer.

"You should pay more attention, I said whoever wins in the series, meaning the whole thing!" explained Maou with a grin on his face.

"Not fair Maou! At least wait for us in the push-ups!" yelled Akohda.

"Alright" said Maou shrugging his shoulders.

Sidelines

No one could believe what they were seeing. The three teens that just entered the school two days ago, weren't just handsome. They were athletic as FUCK!

But along the group of people, three girls knew the secret to their condition.

Magic.

Rias Gremory was standing next to her two childhood friends Akeno Himejima and Sona Shitori, whose last name actually was Sitri. The trio was wide eye like the rest of the group, but for different reasons.

'To use magic with the goal of enhancing your physical capabilities you need to have full control of your magic, master it until the point of perfection' thought the Sitri heiress as she was looking them do sit-ups.

Sona formed a frown when she felt something from the magic the three were emitting.

"Sona you feel it too, right?" asked Rias with a frown in her face without diverting her gaze.

Sona only nodded before finally saying "It's the same one"

"What do you mean?" asked a confused Akeno, who hadn't figured it out yet.

"Their magic feels the same as the one that appeared three days ago" explained Rias to her Queen.

Unknown to the girls, behind them was Adram who heard everything.

'As expected from my brothers in arms' thought Adram who was mentally laughing from looking at the students be stupefied by his comrades.

Adram then looked at the girls I front of him 'Now that Maou-sama has revealed some of his power, we must contact in private with these demons'

Back with the demonic trio

"Done! Now we only need someone to be in our backs to start with the push-ups" exclaimed a very competitive Akohda.

"Well then let's see… Who would like to be on our backs for a moment?!" asked Maou who secretly was hoping that Rias and her two friends raised their hands.

Rias seeing that the rest of the group was still unable to process words, decided to take the lead and grabbed the hands of Akeno and Sona "Hey wai" tried to said Sona but was pulled with Akeno.

"We'll volunteer" informed Rias as she stepped to the front with Akeno and Sona.

'Jackpot' "Okay then, I'll take Rias" informed Maou.

"I'll take Akeno" informed Lucifer.

"Well that leaves me with Sona" shrugged Akohda.

Rias and Akeno blushed slightly by the way they were chosen, while Sona was furious at Rias for dragging her into this.

"Alright you three, hop on!" said Maou signaling them to go with their respective pair.

Rias and Akeno approached Maou and Lucifer without a problem, but Sona was a little embarrassed, because she was about to 'ride' (Dirty minded) on top of a man.

"Hey don't worry I don't bite…" 'Or at least not my own kind' thought Akohda at the end.

"Ready… set… GO!" they started doing push-ups faster than the girls would've expected.

"Sl-low do-own I-I m-mig-ght f-a-all!" yelled Rias who was hugging Maou around the neck, pressing her boobs in his back.

Maou got a bit red in the face due to the humongous breasts that were being pressed against his back, before grinning at this 'Best way to exercise EVER!'

He turned to see Lucifer with Akeno in the same position as Rias, but was more focused than him 'Maybe due to being a fallen angel, anyway, not going to beat me bastard'

He then looked at Akohda who had it rougher than the other two. Sona was hugging him more tightly while closing her eyes, Akohda's face had already turned into a great tomato with some blood coming of his nose, but for some reason was going faster than both Lucifer and Maou.

"Rias hug me tighter" Maou ordered her.

"Wha- Why?!" Rias blushed deeply at the order.

"Just do it!" exclaimed Maou. Rias doubted for a moment, but obeyed nonetheless.

Maou's face instantly turned into a tomato at the feeling of Rias's boobs pressing even more on his back 'So this is the secret to your speed uh? Akohda?' and as the same as Akohda for some 'mysterious' reason he started go faster '98… 99… 100!' "HUNDRED!" and with that Maou proclaimed victory.

After Akohda and Lucifer finished Lucifer started to ask many questions.

"How did you and Akohda managed to go faster?! Why were your faces red?! And why were you bleeding from your nose?!" Akohda and Maou just looked at each other before answering at the same time.

"Secret" Lucifer only became angrier at this but before he could do anything, Rias approached the trio with Akeno in toe.

"Maou-san I would like you to come to the old building in the afternoon and bring your little group too, I want to discuss something with you" Rias invited Maou 'It's finally time for me to get some answers' thought Rias as she started to walk away

"Of course, I'll be there with my 'group', oh and Rias before you go…" Rias turned around to see Maou smiling at her "…you're heavier than you look"

Back with the class and Adram

"Well that was something" muttered Adram "Okay, the rest of you have zero in this class for just staring the whole time, I mean come on guys even the other classes at least tried" informed Adram before walking away.

The students just stood there still unable to process anything, until finally someone broke the silence.

"WHAT THE FUCK JUST HAPPENED?!"

Demon HQ aka House. 3:00 pm

"Maou-sama! What happened to you?!" asked a very worried Ashiya who just looked at his very injured lord.

"Domt wory Achilla Im fimhe" said Maou who had his mouth swollen, two purple eyes and a broken nose.

"What happened to our lord, you are supposed to protect him?!" Ashiya desperately asked the other three.

Lucifer approached Ashiya and putted his hand on his shoulder "Alsiel, believe when I tell the fate Maou got, was inevitable" said Lucifer as if he was giving his condolences to someone.

"Anyway, Alsiel we're going to meet Rias in about an hour from now, so prepare our clothing" ordered Maou with a smirk while healing himself with some magic "we're showing them real demons"

ORC clubhouse. 3:30 pm

"Alright everyone we're expecting guests I want everything to be prepared for when they arrive" commanded Rias to her peerage.

"Buchou, what's so special about them?" asked Kiba who didn't know what happened during PE class.

"They have magic Kiba…" Kiba only kept staring with confused eyes as if asking 'So?' "… their magic is far more powerful than mine, as well as their control over it"

Now Kiba's eyes widened 'More powerful than Buchou, a High-Class devil, where did they come from, an anime?' Kiba thought, without realizing the irony in that.

"Rias, I feel them approaching, they're around the corner outside of the school" said Akeno who had been sitting in a corner with her eyes closed.

"Before we greet them I would like all of you to be ready in case something happens" 'As if we had a chance' thought Rias at the end.

*Knock knock*

Everyone stopped what they were doing. They were wide eyed, ten seconds ago, they were still outside the school 'How did they reached the door so fast?'

Rias quickly composed herself and went towards the door. She took a deep breath and opened it.

Ten seconds ago. Outside the school

The group of demons were heading to the ORC club house, they were dressed in their Demon King and Demon Generals attires, but still in their human form.

Maou suddenly signaled them to stop.

"We're being spied by someone, maybe some of Rias's friends" said Maou to his generals "Let's surprise them and teleport to the front door of their clubhouse"

In a second they disappeared in a black curtain of smoke.

Outside the ORC clubhouse

They appeared in front of the doors of the old building.

"Fiuuuu, it sure looks old" the structure was two story high and was way smaller than the institute, above the door were two wooden windows and what it appeared to be a clock tower, it had plants growing around the doorway and some in the corners "Well let's get down to business"

*Knock knock* the door cracked a little 'Fuck! If I had knocked harder I would've broken the door'

"Are they going to open or what!" yelled Malacoda in anger.

"Patience Malacoda it's only been two seconds" said the PE teacher trying to calm down his partner.

"I swear if they don't open the door right now I'm going to forc" before Malacoda could finish his statement, the doors of the old Institute opened.

"Welcome to the Occult Research Club Sadao Maou, Lucifer Urushihara, Akohda Mahl, Ashiya-sensei and Adram-sensei" after Rias finished talking, she started counting them again "Ashiya-sensei?! Adram-sensei?! Maou I thought I said only you and your 'group'"

Maou looked at Rias with a confused expression 'She didn't realize Alsiel and Adramelech were demons?' "What are you talking about, Rias? This my 'group', now let's go inside so that I can explain you"

"Okay, follow me" she said, quickly composing herself and heading inside.

They entered a living room with some couches, sitting on them already were Koneko, Kiba and Akeno who were keeping an eye in any movement out of its place.

The guest party kept walking until they were across the room, in front of the ORC members.

They looked at each other for some minutes, the ORC inspecting carefully everything they had.

They got curious about their clothing why 'Akohda' only had a cloak.

'Adram-sensei's some shoulder armor and a gladiator like skirt.

Lucifer who was now dressed in a black leather cloak that reached the floor (remember Lucifer is smaller in his human form) and some white pants that were obviously too big.

'Ashiya-sensei' on a dark green cloth with decorations at the end of his shoulders.

And Maou who had a black cloak, with similar decorations as Ashiya's but bigger, some dark purplish shirt and pants that were obviously too big just like Lucifer's pants and the part he was on bare foot.

"So… what you want to know?" asked Maou, breaking the silence in the process.

"First, what are you?" asked Kiba who was worried about what they could do.

"I thought you guys would've already figured that by now, but that aside, we are demons… well except Lucifer over here, he's a Fallen Angel" responded Ashiya who pointed at Lucifer, who was leaning against the wall, to make his answer clearer.

Everyone was wide eyed, except for Akeno who scowled at the mention of Fallen Angel, 'They're demons? Not devils? That might explain why they're magic is something I've never seen before' thought Rias but even after hearing that she still had a hard time believing them, her brother had once told her that demons had monstrous appearance in comparison to them devils.

"So you're demons? Not devils? Your aura does feel different than a normal devil or fallen angel" questioned Rias who couldn't believe what she was hearing.

"Devils? Never heard the term, we're just some ordinary demons; here… Let us show you our true form" Maou said with a dark voice.

All of them stood up before energy started to flow from their bodies and started to surround them 'Their magic is as dark as the magic of destruction of Onii-sama' thought Rias amazed.

After a moment, the air became harder to breath, the dark energy started to dissipate and a cloud of smoke that reached the roof was everything that was left.

"Well, they gave us a good light show and now they're gone, great" said Kiba in an arrogant tone, turning around and about to leave.

"Some light show, you say?" a shiver went down Kiba's spine. He slowly turned around to see the source of the sinister voice. When he fully turned around, he still saw smoke so instead he turned to see Rias, Akeno and Koneko and was shocked. They all had scared expressions on their eyes "A good light show would be when I used to burn down human's villages with my bare hands"

As the smoke started to dissipate, five figures stepped out to the light.

The first one to come out of the smoke was a giant minotaur, that only had muscle in his body, he had on the armor 'Adram-sensei' arrived with. His horns were almost as big as his head.

The second one was a pale figure that was wearing 'Akohda's' cloak, when the creature rose his head, it was revealed to be a human skull with red glowing eyes in the empty sockets.

The third was a humanoid figure with blonde-white hair just like 'Ashiya's-sensei' it had black armor-like skin around all his body and some on his forehead and eyes.

The fourth one was Lucifer, the only difference was his stature, his hair length and the two giant wings coming out of his back.

And in the center of them, came out the most intimidating being they've ever seen. It had two bronze horns sticking out of his dark green hair, goat like legs with white fur his clothing was the same as the one's Maou had on, but the only difference is that now they were skin tight due to the being's muscles. But the most intimidating asset were the glowing red eyes. In them one could see great power.

"What? Cat ate your tongue?" mocked the being in the center, which scared all of them "Scared? You bring shame to the word demon, or in your case whatever 'devil' is"

At that last comment, everyone tried to calm themselves, but was futile, how were they supposed to calm themselves with those monsters in front of them?!

After a minute, they were able to calm themselves a little, but the monstrous demons could still sense their fear "Now you'll show us your "devil" form, if that's what you call it?" The voice kept bothering them, but they tried to ignore it.

"Devil form? W-we don't have o-one" spoke Rias for everyone, "this is ourn natural form" the beings in front of them looked at each other before starting to laugh.

"Nice joke…" the giant minotaur said wiping away a tear, trying to hold his laugh "… now seriously show us your devil form"

At this the ORC members just looked at each other for a moment with confused looks before looking back again to the demons in front of them "We really don't have any idea what you're talking about"

They suddenly stopped laughing and looked at the ORC group with stupefied looks "You're not joking" said Lucifer.

"Well at least I can tell you who I am" Rias said wiping away all her fears "My name is Rias Gremory heir of the Gremory clan one of the 72 purebloods, this is my peerage, Akeno my queen, Kiba my knight, and Koneko my Rook while I'm the king" she paused for a moment to catch air "I'm sister of one of the four Maou, Sirzechs Lucifer"

After this statement, all the demons from another world were thinking one thing 'WHAT THE FUCK DID THIS BITCH SMOKED?!'

"Okaaaay… now that you introduced yourself and your whole… peerage?... I'm going to introduce ourselves" said the creature that took Maou's spot "Behind me are the greatest demons Hell has ever seen, Malacoda the Necromancer, Alsiel my strategist, Lucifer the most powerful Fallen Angel, and Adramelech the strongest demon in brute force… they are the four great generals of the demon army" Maou made a pause for suspense "And I… My name is Satan Jacob, leader of the demon army and Demon King itself." He finished his grin growing wider.

As Satan finished his statement he was greeted with silence 'The Demon King Satan no that's impossible' Rias kept denying the probability of the first Demon King being alive 'he died thousands of years ago, wait… his second name was Jacob?'

"Hmpf, you can't be the Demon King" Rias stated, making Satan raise an eyebrow "You said your name was Satan Jacob, but the real Demon King was named Satan Lucifer!" all the ORC members nodded their heads backing up their buchou.

"Oi, oi, oi I'm the Demon King from another world, I never said something about being the Demon King of your kind" Rias felt insulted by the way she was referred as growing a tick mark, but before she could respond Satan started to talk again "I mean seriously, if you say you can't transform then you should've already figured we're not from here" all generals nodded agreeing with what their King had said.

"Okay, okay I get it you're from another world, no need to rub it on my face!" Rias said feeling angry at the way this demon was treating her.

"Yet, you're still all demons Rias-san or at least some variation of such, could you please tell us how you identify yourselves" asked Alsiel in a very polite way, to don't cause a needless fight.

"Well we usually can feel others auras, but if we can't we just show our wings" At the mention of wings Satan and Lucifer eyes were sparkling.

"Wings you said?" asked Lucifer barely holding his excitement.

"Yes why? Want to see them?" Satan and Lucifer nodded their faces rapidly.

After two seconds, out of Rias's back, a pair of wings came.

Satan's and Lucifer's face suddenly became… poker.

"Rias… *Mm* … what the fuck are those?" asked the Demon King with a blank expression.

"My wings of course" answered a rather confused Rias 'Can't he tell this are my wings?'

"Rias those are like a bizarre version of wings" said a very disappointed Satan.

"What do you mean? all devils have them" this time spoke Kiba who revealed his along with Koneko.

"THOSE AREN'T WINGS, WINGS ARE LIKE THE ONES LUCIFER OR I HAVE!" yelled a Satan who was on the verge of throwing up.

"What? You don't have wings!" countered Rias who was angry for her wings being insulted.

"You're right…" *smirk* "… I forgot to take them out" from Satan's back a pair of majestic wings came out.

"Your wings are incredible as always, my lord" said Alsiel.

"Can I touch them?" asked Koneko who fearlessly approached the Demon King.

"Hahahaha! These are the type of demons I'm looking for, those that aren't scared of the unknown!" he said while looking down at Koneko, who blushed a little at the compliment "Of course you can!"

Ten minutes later

"Okay, Rias I think we diverted a lot from the actual matter" Rias only nodded "Now tell me about these world's demons"

"Well where do I start" Rias thought for a second"Okay, thousands of years ago, the Heavens and Hell were created, the entity named God ruled from above these two zones with his archangels. God later created a world that stayed as a line between Heaven and Hell, which was Earth, in Earth the humans took residence. During the first years, everything was okay, but soon it was reported in the Heavens that whenever a human would die he would reincarnate as a demon in Hell. God made this stop, but hundreds of thousands of humans had already perished by the time he did that. As the years passed by, one of God's generals, Lucifer, got bored of Heaven and started to have impure thoughts such as war, thus making him the first Fallen Angel ever. Lucifer hated being a Fallen Angel because he still kept his feathery wings and some of his holy power, so he decided to burn his wings, only leaving their bones, transforming into the very first Devil.

He traveled the Earth to find a way to get back at God but instead he found that other deities were starting to surface, but that wasn't what he was looking for, so he decided to go where all humans souls went if they had a bad life. Hell. In there he found chaos, war, devastation, all he wanted when he still resided in hell, and as such he did the most reasonable thing he started fighting all the demons to show them his superiority in skills and soon after he defeated almost every demon he proclaimed himself the Demon King, even though he was a devil, and added to his name Satan.

The Demon King, Satan Lucifer, found God's first female human, Lilith, and alongside her they created a new race to live in the underworld and rule over: Devils. Beings that resemble the angels of heaven in every way, but deviate by having bat-like wings and the ability to use demonic magic. All previous demons were turned to resemble devils, but there were many who refused as they hated resembling the angels from heaven, but knowing they couldn't challenge Lucifer they exiled themselves from the Underworld, and spreaded themselves along the different levels Hell offered. And like that the dominant force of Hell became the devils, with demons not once ever, setting foot in the surface."

A the years passed by Lucifer had grown pleasant as the ruler of the Underworld, and granted other great three Devils, titles close to Demon King but not quite so. They became the four most powerful clans in the Underworld, Lucifer, Leviathan, Beelzebub, and Asmodeus they became the main figures and later leaders of the Underworld. Fallen Angels were discovered to also reside in the Underworld along the devils, and an agreement was made to divide the Underworld between them. Everything was fine...until it wasn't. No one knows how or why, but war broke out between the now three factions.

It was a bloody conflict that lasted for thousands of years, until a few hundred years ago a stalemate was reached, our four Leaders were death and the Devil's faction broke into civil war, between the old-Satan faction who wanted to prolong the war, thinking the devils could still win, and the Anti-Satan faction who knew the devils were too low in numbers and exhausted to continue fighting. Eventually the Anti-Satan faction won, and the four most powerful devils were given the titles of the former great Houses, to establish their authority across the Underworld.

"That brings us to the present, where my brother is one of the Maou and have kept the status quo with the Fallen Angels and Heaven." Rias finished.

The Entean demons where amazed of how much history this world had, all of them were wide eyed and opened mouth, well, all except for Satan who had his eyes closed processing the information he just received.

"Lucifer, this world's you had a similar story to yours, but did you thought of making yourself into a demon?" asked Satan looking at Lucifer waiting for his answer.

"Yes, at some point I thought of burning my wings of and becoming a demon just to challenge the heavens…" Lucifer explained. Everyone was surprised they didn't know this about their comrade "… but that was before you appeared and united the demons under one banner" this made all sigh in relief they didn't want a bloodthirsty comrade who would burn his wings just to get some war.

"But would you look at that Satan I became this hell's demon king instead of you, you should be a bit jealous about that" Lucifer said with a proud smirk on his face.

Satan let out some of his power, making all present pale a bit "Don't get to full of yourself Lucifer, where we come from you're still my general and don't forget who is your king" Satan said with a playful tone but more sinister voice making Lucifer pale more than the rest.

"Hai!" he said barely able to contain his fear, while the other generals where chuckling.

"Ahem" 'coughed' Rias taking the attention of the foreign demons "now that I told you our story what about yours"

"Yes, of course, I almost forgot" started Satan "We come from a place named Ente Isla, you could consider it's stuck in a type of middle age technology with swords and armors. The demons story is different from yours though. The demons and the humans used to coexist with each other they would treat each other equally. But then out of nowhere the church showed up with the false ideology that we were evil that needed to be erased from the world. They started hunting the demons down and forced them to retreat to the demon world, which was actually the red moon of Ente Isla, and yes there are two moons."

"The demons eventually started to fight each other and learned to draw magic from negative emotions. I was a low-class demon a Black Goat demon, some of the lowest class, my name Satan is very common, we were a pacific tribe, but were slaughtered by another tribe, they left thinking everyone was dead or would die eventually, I waited for my demise. but was rescued by an Angel who told me 'She had never seen a demon cry'"

"The angel taught me everything I know, and was the first one to ever call me 'Demon king Satan', one day she left me and left some sort of seed that I never knew what it did. Anyway, moving along, remembering how the humans considered us weak I set myself on the path of uniting my race. I became a leader of a faction and started the battle for unification. It lasted over fifty years and organizing the tribes took another seventy years."

"Then I realized my mistake. The demons fed from negative emotions that were held due to the constant wars between factions/ tribes, since I made Hell a pacific place I decided to conquer Ente Isla and subjugate the humans in there so that they held grudge towards us. Conquering the continents was easy job for my generals, but not much later a Hero arose and started to push back my forces one by one, Alsiel over here, advised me to call back the armies and all generals, since I trusted Alsiel I did so."

"The final battle between the Hero and his allies and the Demon King and his generals took place in the center continent where I had established our HQ. I killed the hero and everyone behind me were able to beat their opponent without much effort," he stopped and looked at Alsiel and Lucifer "except for Alsiel and Lucifer who apparently had a little problem with a Loli" another pause "when the battle was over and I had spent half of my energy fighting the Hero, heaven's army finally decided to join the battle and forced us to retreat to here." And now Satan finished.

The information was easier to process to the Occult research club since it was less than what they had been taught.

The first one to talk was Kiba who was looking at the Demon King in front of him "Wait, so you were born a low-class demon and made your way up to the top, just how old are you?!"

"I'm 300 years old and before you ask, my generals are way older than I am, Adramelech is 700 years old, Lucifer about 1,000, and Alsiel and Malacoda something around 1,500 years." Satan explained answering unsaid questions.

"So, you arrived here three days ago, right?" asked Akeno verifying something, they all nodded as their response, she immediately looked at Rias with a shock look in her face.

They were the powerful energy that appeared days ago.

"What's your purpose here?" asked Rias still shocked about the news.

"At first we wanted to go back as soon as possible…" he looks up and gives a small grin "… but now I think I would like to conquer this world"

Everyone was shocked beyond belief; how would they answer to that? A being with a power equal or higher to a Maou-class devil.

"But seeing your reactions I believe you guys are against the idea so I'll just ask you this:" Satan said in a more serious tone than before, his hair shadowing over his eyes.

"Will you join my army?"
