"Humans! I shall grant you Ente Isla for now. But know this, I WILL be back, and the whole world will tremble under my rule!"

With that, a figure flew into the sky, spreading his bat-like wings as he did so. He had glowing red eyes, wore a heavy black cloak and cape, and had two curved yellow horns on his head, one of which had recently been sliced off at the base. His legs were also comparable to goat's legs. All of this combined to reveal his demonic nature.

He was the Demon King Overlord, Satan Jacob, and his castle had just fallen prey to a suprise attack by the humans, led by none other than Emilia Justina, known by her fellow humans as Emilia the Hero.

Said Hero was currently looking up at the sky, glaring at the Demon King as a glowing purple portal appeared behind his massive frame. She watched as he prepared to flee, before she leapt at him.

'After all he's done to Ente Isla, there's no way I'm letting him escape!' Emilia thought, as she flew through the air.

As she flew, she saw Satan enter the Gate, and noticed his closest general, Alsiel, preparing to follow. Not wasting any time, she sped up, intercepting the Demonic General in mid-air. A brief scuffle ensued, as the two briefly traded blows.

However, upon noticing the Gate beginning to close, Emilia managed to knock Alsiel down to the ground, using the flat of her sword, Better Half. Immediately, she turned and fled towards the Gate, barely having enough time to pass through before it dissolved.

Fighting against the priests that restrained him, Alsiel cried out, "MY LOOOORD!" before he was subdued and captured.

*~Tokyo, Japan~*

In an unused alleyway, two figures, one male, the other female, appeared out of thin air after a brilliant flash of light. Both of briefly stumbled, before being a look at one another. One wore a heavy black cloak, under a black cape with shoulder guards. His dark hair was swept messily on the top of his head, and his red-orange eye widened in surprise at the sight before him.

You see, Emilia's armor needed a respectable amount of Celestial Force to be summoned and used, as with her sword, Better Half.

The problem with this new world, however, was the utter lack of Celestial Force, or any type of magic whatsoever. Add that to the fact that her armor would become blistering hot in the Ente Islian summer climate, practically forcing her to fight in her undergarments, and you have a recipe for indecent exposure.

The two stared at each other for a good minute, before Emilia lunged at him, taking him down and forcing the both of them out in the open.

"Die, Satan!" She yelled, attempting to stab him with her now non-existent sword, before noticing her lack of sword. That, and the sudden breeze that alerted her to her lack of armor, caused her to blush, and start and punching him.

Again.

"Dispatch, we have a young couple here who are suspected of having indecent relations in public and we're heading back to the station." Officer Sasaki said, as he watched his partner guide the bickering pair to their squad car.

He wasn't surprised by the fact that he couldn't understand them, having already discovered the fact when he first noticed them, the girl practically half-naked as she straddled the boy with a fist raised.

"Roger that, bring them in."

The Officer sighed, as he decided to add the last bit of info they recently found out. "Uh, Dispatch? They don't seem to understand any Japanese."

There was an audible sigh over the radio, as the dispatcher vented his frustrations. "Alright, we'll try our best over here. Bring them in"

The officer looked into the rearview mirror, watching the two as they glared at one another. Besides him, the passenger side door opened, and his partner climbed into their cruiser. After a brief nod, he started up the cruiser, and drove off.

"You will tell me everything there is to this world." Satan said, as his eyes briefly glowed a blood red.

In front of him, was Officer Sasaki, who was assinged to help the foreigner. His eyes were currently glazed over, as Satan's magic did it's, uh magic.

"Yes."

*~A few hours later~*

"This is utterly humiliating." Emilia mumbled, as the two trudged through the streets of Tokyo, the morning sun just peeking over the horizon.

She was clad in a green tube top and blue skirt, both of which she received due to a police woman's generosity, but she was uncomfortable wearing.

Besides her, Satan chuckled, as they stopped in front of a man-made pond. He would've preferred to leave the griping hero back at the... 'Police Station', was it? But he took her along with him, mostly for his own amusement. And partly, he admitted to himself, because he needed help in getting back to Ente Isla.

'This whole situation is unprecedented.' He thought, as he let himself wonder what he did wrong. 'The Gate was supposed to take me back to the Demon Realm. Why is it that I find myself in this 'Tokyo', in a human body, no less?' He pulled himself out of his musings, instead turning towards the 'Noble Hero' that was currently spewing out obscenities that would surely land her a ticket straight to his domain.

"Emilia." He started, earning him a sharp glare from the woman. Gulping as a sudden feeling of nervousness overtook him, he forged on. "It should be clear to you that this world contains no magic. It would be in our best interests to wor- work together." He said, choking in mid-sentence as his distaste nearly made him vomit.

"Like hell I would!" Emilia yelled, turning towards him, her green eyes blazing with rage. "Give me one good reason why I should even CONSIDER siding with the Demon King!"

Satan smirked. "Earlier, I used my hypnotism to find out how this world works. I also have a good grasp of the local dialect. Face it Hero, you need me."

*~Integration~*

"I can't believe this." The Hero grumbled, as she looked around the interior of the Ward Office. Just in front of her, she observed Satan with dark satisfaction as he struggled to focus the magic he needed to hypnotize an official, and acquire them an identity.

They went through easily enough, with the aid of Satan's magic, and they soon had new identities.

*~Funds~*

After they acquired citizenship, 'Sadao Maou' led 'Emi Yusa' to a small building he referred to as a 'bank'.

"What is that?" Emi asked, pointing to the thin sheet of paper Maou held in his hand.

Maou smirked. "You wouldn't know. This piece of paper I hold in my hand is the local currency." He said, as he waved the ¥10000 note in her face.

Emi scoffed, ignoring the yen note. "That flimsy piece of paper can't possibly be the currency."

That's when a smug-looking man walked past them, a greedy glint in his eyes visible as he counted a large stack of bills.

"Not a word." Emi growled, as Maou just smirked.

*~Housing~*

"W-we need a r-room." Maou said, in heavily accented Japanese.

'This'll never work.' Emi thought, not understanding a single word of the conversation. Although, judging by the way Maou's face shone with triumph, he managed to secure them a place to stay.

Emi stared at the house with barely-contained annoyance. She knew, through experience in her travels, that they would most likely only recieve a single room in the run-down house.

And it looked like she was right.

Walking inside, the two just stared. The walls were thin, the space was small, and the whole place had a thin layer of dust.

"Don't worry, it's not as bad as it looks."

Emi and Maou both spun towards the speaker, a heavy woman that wore a ridiculous amount of purple. She wore a purple dress, had a purple sweater tied around her neck, and had on a purple hat with four yellow feathers and a single green feather attached to it. Although her appearence startled the two, what made the both of them wary of her was the fact that she spoke in the language of Ente Isla.

Switching back to Japanese, she thanked the Real Estate man, and watched as he left. Afterwards, she turned to the two, and addressed them, back in Ente Islan.

"I don't know how you two ended up here, nor do I recognise you two. My name is Shiba Miki, and I look forward to being your landlady." She said, as she took to the stairs. However, before she left the property, she turned to the two, and said, "Oh, and call me Miki-T."

The two stared her as she left, both of them feeling tremors whenever she walked.

"I-is she really human?" Maou asked, as the sun set overhead. Besides him, Emi hesitated, before faintly nodding.

*~Later, 8-9 at night~*

The two sat in uncomfortable silence, both staring at the floor. Maou, however, was in deep thought. 'In this world, they say vengeance is worth suffering for, but am I sure that's what I want anymore? I've learned so much about this world in such a brief time. Frankly-' he swallowed a sudden lump that formed in his throat. 'It appeals to me.'

"We'll only have to put up with this for a brief time, right?" Emi asked, breaking the silence, and Maou's train of thought.

"Y-Yes." He said, squinting his eyes as his vision became fuzzy. "We need to figure out what to do from here on out, and work... from..." Maou's vision suddenly faded, and he slumped over, now laying on the cold floor.

Alarmed, Emi checked him over, figuring out soon enough that he fainted from lack of 'sustenance' as he would call it. She chuckled, finding the idea of the Demon King dying from hunger amusing, but ultimately decided she needed him alive.

She lazily stood up, briefly stretching, before walking to the door, taking the stairs down, and looking for help.

'This shouldn't be that hard, right?' She thought, before recalling the language barrier currently in effect. In other words, she can't understand the locals, and vice-versa.

She slumped, and decided she would be better off in the long run if she hurried up.

...just a bit.

*~Morning - Hospital~*

"To think this body even requires the ingestion of food..." Maou said, with his head held in his hands. Next to him in a separate seat, Emi smirked.

"Of course it needs food. It's a human body, after all." She said, emphasizing the word human.

"And to think that one infusion is worth as much as a month's rent of my stronghold?!" Maou exclaimed, standing up in the process, as Emi scoffed. "Stronghold?"

"This is what they call a 'rip-off' in this world!" He ranted, as they exited the hospital. Once they were outside, he calmed down a bit. "But if you hadn't ran into that weird landlady, I wouldn't have made it." He said, before taking a deep breath. "T-thanks for helping me."

Emi stared. Was the Demon King thanking her?

Growling at the look on her her face, Maou ignored her, instead realising a solution to their problem. They needed the one thing that 'makes the world go 'round'. "We'll need more money if we're going to live in human society, and I can't get that easily, since I can't afford to waste what little magic I have left." He said, turning to the now sullen-looking Hero.

"That must mean we only have one choice, right?" Emi asked, receiving a nod in return.

*~Evening~*

Emi glared at the paper that laid on the box in front of her. "Is this a joke?" she asked as she glared fiercely at Maou, who was busy filing out a sheet of his own.

Looking up from his MgRonald's application sheet, Maou asked, "What's wrong, Hero?"

Emi's glare intensified, as she roughly snatched he sheet from the box and shoved it in his face. "Does this look like something I would understand?!" She yelled, prompting Maou to cover his ears in an attempt to protect them.

"You don't have to yell..." he muttered, before snapping his fingers. Instantly, the words on her application sheet became readable, as the symbols changed and rearranged themselves. Emi was suddenly holding an Ente Islan application for a language class.

"That better?" He asked, before being back to his own sheet.

"...What did you do?" Emi asked, after starting at the sheet for what seemed like hours.

Maou sighed, before explaining. "I didn't do anything special, just change your perspective."

Narrowing her eyes at Maou, Emi asked, "What do you mean by 'changing my perspective'?"

Maou however, just waved her off. "Don't worry, all I did was make it so that until you learn the native language, anything you see that is written will appear in Ente Islan script. It'll wear off when you learn Japanese."

"Couldn't you just transfer your knowledge of the language to me directly, instead of just the words?" Emi asked, anger rising at what she thought was Satan trying to amuse himself.

Not bothering to look up as he finished the form, Maou answered her. "If you were a demon, then yes. But you're not. You are a human, and for me, it takes a considerable amount of magic to do that, since humans work differently from demons."

Seeing her prepare to ask another question, Maou decided to add, "All I used was a modified Deception Spell, which is ridiculously easy for me to perform."

After a moment of silence, Maou decided to ask a question that's been on his mind for a while now. "Don't you have any magic left? Is seems odd that I'm the only one using any."

Emi blinked. She actually hadn't even bothered to check. Taking time to search within herself, she found she had enough to summon Better Half, as well as her boots and gauntlets, for at least a few minutes, and just a little more, for minor magic and a shield or two.

Instead of telling him, Emi merely shakes her head.

*~The Next Day - Emi~*

Emi stood in front of the run-down building, checking the address on the now-readable paper. This couldn't be the place.

It was a single story building, it's white paint containing a brown coat of grime, the windows dusty, and the sign clearly reading that this WAS in fact the right place.

Emi took a deep breath, while thinking 'Let's get this over with.' And walked through the door.

*~Maou~*

"Thank you again, Miss Kisaki, for accepting my application on such a short notice." Maou said, as he was led towards her office on the second floor of the MgRonald's.

"No problem," the red-clad woman said, waving her arm in dismissal. "We really need more employees right now. This place is deserted." Reaching the door, she opened it, letting the Demon Lord inside.

Her office was fairly large, containing two bookshelf's, one filled with random texts, the other filled with personal belongings. A desktop computer resided in a corner, and in another were two small couches that faced each other, separated by nothing other than a small wooden table. She led him to the couches, and he sat down, back stiff at an attempt to be formal. So it came as a shock to Maou when Mayumi casually lounged on the couch, eyeing him with interest.

There was a brief moment of silence, as Mayumi studied him, before she suddenly stood up.

"You're hired."

Maou's eyes widened in shock. "W-what? Just like that?" Maou managed to sputter, as his new boss chuckled at his reaction.

"Then what was the interview for?" Maou finally asked, after calming down, to which Mayumi shrugged. "The interview was just a formality. Besides, I like meeting the people I hire before I blindly send them off to work." She explained. Seeing the questioning look, she sighed, before adding in, "An interview tells me nothing about yourself. I don't know if you can be trustworthy or not. A person can seem eager and energetic for the job at the interview, but they can easily turn into lazy bums during work." A look of understanding flashed on Maou's face.

"You want me to prove to you that I want the job, right?" He asked, Mayumi nodding in response. "That's right. You can start tomorrow."

"Get up!"

A little demon child lay on the dirt, his goat legs caked with a mixture of mud and blood, and his raven hair in messy spikes, almost hiding his tiny horns. In front of the child stood a white-robed priest, a scowl etched on his ancient face. Behind him, younger priests attempted to restrain a larger demon with goat legs and bull's horns, and a she-demon, with red skin and ram's horns.

The little boy got back up on shaky legs, only to get blasted by the priest. The boy flew through the air, until his back collided with a tree.

Seeing the boy get hit with a blast of holy energy, the larger demon fought against his restraints with renewed efforts, managing to snap those that crossed across his chest. Calling upon his remaining magical energies, he knocked the priests trying to restrain him once more straight into the air, their horror-filled screams silenced only when they landed on the unforgiving earth with sickening cracks.

"You DARE touch my heir, human?!" he roared as he rose, a ball of crimson magic forming in his palm.

The ancient priest merely scowled. "I dare, Satan. You and your demons have finally been declared as a threat to humanity. None of your kind are allowed to exist anymore." He spat, as a white rune circle appeared in front of him, a pinprick of light appearing in it's center, charged with holy energy.

"You will regret attacking the Demon Overlord, human." Satan growled, as he hurled the cracking sphere. The priest responded in kind, and the tiny sphere of light was suddenly surrounded by hundreds more.

In an instant, hundreds of thin, destructive beams filled the air, completely engulfing Satan and his bride. Satan's attack, however, barreled through the onslaught, and collided with the smug priest, annihilating him and everything within a ten foot radius.

Little Jacob was the only witness left that day. He then watched helplessly, as his father soon succumbed to his wounds, and fell.

Maou shot upwards, woken from his slumber on the floor by the memory. He sighed a ragged breath, as he willed his heart to stop pounding.

After calming down his frantic body, he looked over to an ancient analog clock, which read 4 a.m. Seeing that he wouldn't be falling asleep any time soon, he got up and left the small apartment, taking a brief moment to look at the sleeping Emi Yusa, whose slumbering face held a smile at her pleasant dream.

That day, Sadao Maou decided to start his first shift at MgRonald's early.
