The Devil woke early the next morning to find his sister snoring loudly, looking far too comfortable for her own good. He was tempted, for a moment, to kick her in the shin, as his had bruised up and was still sore. Instead, he grabbed his wash bag and walked down to the bathhouse so that he could bathe and get ready before work.

As he sat in the bathhouse, letting the hot water soak into his sore muscles, he found that his sister's reappearance was much more troublesome than he had realized, especially given her level of self-confidence. Helena Jacob, the Demon Queen of Ente Isla, was a stubborn, hotheaded girl who was convinced that she was always right, and never wrong.

She was impulsive, but she was also incredibly intelligent and cunning. The end result being that Helena thought herself far superior to the Demon King. It was true, in a sense, for much like in the animal kingdom, the female was always larger, more dominant, and ferocious.

The same went for demons and demonesses.

Maou felt a twinge of guilt for thinking so poorly of his sister. The truth was, he owed her his life. There was a time, before Maou had unified several wandering demon tribes beneath his banner, during which his sister was the only one who cared for him. She protected him, and kept him safe. She kept them alive, even when it was just her against the entirety of the harsh, predatory landscape of the Demon World. Nothing ever daunted Helena from protecting her idiot little brother.

Even when Maou was ungrateful, or felt her rules were too strict, Helena always put him first. Together, they lifted each other up, coming farther than any other demon had in regards to their consolidation of power. When it came time for Maou to select a Queen, he couldn't have chosen a better one than his sister, for who else would have the crass to tell him if an idea was stupid and wouldn't work? Who else would watch his back, and make sure that no harm came to the Demon King?

They fought, of course, as all siblings do, but at the end of the day, it was Maou and his sister against the world… perhaps, with some careful flattery and a few choice words, Maou could wriggle his way back into his sisters good graces… she couldn't stay mad at him forever, could she?

"Maou, you idiot, I was supposed to come into work with you!"

Maou had already been at work for several hours, and it was the lunchtime rush when Chimei had stormed into the Hatagaya MgRonalds, Ashiya trailing behind her, and looking rather upset with himself.

"Chimei," Ashiya muttered, "you said you only wanted to come say hi, and to buy some lunch!"

"I lied," Chimei shrugged before turning her fury back to her brother, who was still trying to smile at the register, though perspiration dotted his brow.

"You were supposed to wake me up, bring me with you, and get me a job here!"

"Is there a problem," asked a stern female voice.

Mayumi Kisaki, Maou's boss, and the Manager of the Hatagaya branch of MgRonalds, came out onto the floor, stopping right before Chimei.

Almost as if they were mirror images, Chimei and Kisaki both crossed their arms and leaned heavily upon one leg, taking a stance that said 'I'm not gonna put up with your crap.' Ashiya stared between Kisaki and Chimei, noting their eerily similar features. They appeared to almost be the same age, though Kisaki had a few years on Chimei's human form, and Chimei's indigo hair was a few shades darker that Kisaki's hasty purple side ponytail.

"Family business," Chimei said, an eyebrow raised in defiance.

"Ah, so you're related to one of my employees," Kisaki asked, her friendly tone matching her cold smile.

"Yeah, that twerp," Chimei said, pointing with her chin at Maou, who almost felt the need to duck behind the register as both women turned to stare at him.

"I see. Even so, I'm afraid I can't allow any sort of confrontation. Maou is my employee, and he has a lot on his plate, what with the lunchtime rush starting. Please order your food, and make sure to speak with him on your own time."

Kisaki's tone was rather decisive, and she turned away to stalk back to her office, sure that nothing else would happen. Chimei smirked for a moment, watching Kisaki leave before stepping right up to the register, a handful of yen clutched in her talons.

"That woman is wife material," Chimei said, winking at Maou, who blanched.

"She's my boss," Maou muttered.

"Still, you need a good woman in your life… someone who can whip you into shape when I'm not around," Chimei laughed, "anyway… let me get two number nines… a number nine large… a number six with extra dip… a number seven…two number forty-fives… and a large soda."

"Geez, I sure hope you're ordering for everyone, and not just for yourself," Maou said, punching in the order and reading out Chimei's total.

Ashiya watched warily as the Demon Queen counted out the notes and handed them to her brother. Maou made change faster that Chimei's eyes could follow, and with a professional smile he gave her the food, which was made rather quickly, as it was all hands on deck in the kitchen.

"Thanks for your patronage," Maou remarked, "please come again!"

Even as he said it, however, he sincerely hoped that Chimei never entered the Hatagaya MgRonalds again… perhaps there was a branch a little farther away that would be a better fit for her.

Maou worked through the lunch rush, and after about an hour and a half, things slowed down considerably. He was just about to go on break when one of his coworkers came up to him, telling him that Kisaki wanted to see him in her office. Maou, thinking that his break would have to wait, figured that it was best not to keep her waiting.

He found Kisaki sitting behind her desk, pouring over what Maou recognized to be his employee portfolio, which was filled with signed documents, notes on his performance, and assessment forms. On the top, however, was Maou's original application, still scribed with poorly formed kanji, as he was still new to writing when he'd filled it out.

"Maou, I've been looking through your file," Kisaki said without looking up, "and while your performance has been stellar… I don't see anything in here about any sort of family. Care to explain what that woman was doing here?"

"That was my sister," Maou said, "she was raised… where I was raised. I haven't seen her in a while."

"I suppose that would explain her lack of etiquette. Why did she think that you would be able to get her a job here," Kisaki asked, causing Maou to stiffen in his chair, "you didn't tell her that-"

"No! No, I don't want her working here," Maou said suddenly, "it's just, she moved in and I'm supporting four people, and when I told her as much, she assumed I could get her a job. I didn't promise her anything."

"Does she have any skillsets?"

"Aside from being a pain in my ass?"

"Yes, aside from the basic sibling behaviors," Kisaki said, "is she as strong willed as you are?"

"More so," Maou replied, "almost to a fault."

"Loyal?"

"Again, to a fault."

"Is she quick on her feet? Good with her hands? Does she have any experience in working in a fast paced environment," Kisaki asked, firing off questions like bullets."

"Well, I mean, I guess she can move fast," Maou said lamely, thinking back to when the Demon Queen had fought at his side, "she's certainly no slouch."

"Is she reliable?"

"That depends," Maou shrugged, "she can be temperamental."

"Like when she stormed into my restaurant and demanded a job," Kisaki noted.

"Yeah."

Kisaki frowned, looking as though she was divided about something. Maou was wondering what sort of punishment he would get for his sister's indiscretion.

"When can she start?"

Maou's face fell, and suddenly he was on his feet, looking thoroughly outraged.

"You can't be serious," Maou cried, "the girl's a menace!"

"She's got spunk," Kisaki said with a shrug, "she reminds me of a younger me."

"She's nothing like you, and that's a compliment," Maou said quickly, pacing back and forth in front of his boss' desk.

"Give me some of her weaknesses," Kisaki demanded, smiling politely at Maou's discomfort, "what are some areas she can improve upon?"

"Are you seriously still considering her as a candidate," Maou asked, his voice shrill as he stared at Kisaki, "again, she's a menace. She's rude in the extreme, she sleeps late and isn't even a functioning member of society. It's like she's still in middle school, except I've gotta take care of her!"

"So, would you say that she's a bit directionless? Like she's looking for a cause? It sounded to me as though she really wanted this job…"

"There are other jobs-"

"But where else will she have a loving brother to show her the ropes? I think it'd be a good idea for the both of you to work here," Kisaki said suddenly, her eyes shining as she stood from her desk, looking as though she'd had an epiphany.

Maou froze, sure he wouldn't like what was coming.

"Tell her she starts next week. Bring her in over the weekend so we can process the necessary paperwork. You, Maou, will be your sister's safety net. It's your job to train her in, and to make sure she follows protocol. If she's still here after ninety days, I'll not only give you an excellent referral bonus, I'll give you a raise! I get a new, hardworking staff member with a built in support system, and you get paid quite handsomely. How does that sound?"

"I…"

Maou was speechless. On one hand, there would be the painful aspect of dealing with his annoying older sister every day at work. He would be completely responsible for any screw-ups, and any accidents. If things went poorly, Maou would be the one to suffer for it, and his reputation would be tarnished.

On the other hand, if things went alright… well, Maou had heard some very good things about the referral bonuses. And a raise on top of it? Plus, his sister helping to pay the bills? It was a risk, a gamble he wasn't sure he should take… If only Ashiya were there, Maou could consult him on probabilities, and use his strategic insights, which would surely pick up on anything Maou may have overlooked.

"I'll tell you what," Maou said suddenly, "how about I tell Hele-I mean, I'll tell Chimei about the job offer. I'll make sure she's given it a lot of thought, and will be a good fit… then, if I feel she's ready to enter the workforce, I'll bring her in this weekend to finalize paperwork."

"I'd expect no less," Kisaki said, looking rather serious, "your reputation as our hardest worker will be put to the test, and you have to make sure your sister will last here. You know I have no patience for slackers or pushovers… take the week, impress upon her the importance and duties of the job offer, and if you feel she's a good fit, bring her in. If you think it'll take a bit more time, I can wait, but if you don't see any signs of promise in her… well, it's best to get rid of the irritant before it grows into a real problem."

The Devil looked at his boss carefully, wondering what in the hell she was talking about. Did Kisaki just suggest Maou dispose of his sister… or was she simply referring to getting rid of bad employees before they cause problems? Whatever the case, Maou felt his night fly by as he tried to think of a way to approach Chimei in regards to the problem at hand. To his knowledge, the Demon Queen only had one weakness, and that weakness was-

"Chocolate!"

Maou kicked in the door to his apartment, and turned on the lights, forcing everyone on the floor to shield their eyes from the brightness. Ashiya and Urushihara usually stayed up pretty late to accommodate Maou's return from work, but it seemed Chimei had demanded they all turn in early. Even Urushihara, who ususally stayed in the closet to sleep, was lying out on the floor, looking displeased.

"Ch-Chocolate?!"

Chimei's frown turned upside down, and she sniffed the air carefully, as if she could actually smell it. Chocolate was a very rare commodity in Ente Isla, and the Demon Queen, who'd sampled some after conquering most of the known world, had gotten a very serious addiction to the stuff.

Now, however, she sat up and scooted towards the table, not bothering to notice her brother's very forced smile. Maou set a plastic shopping bag down on the table, and from within, Chimei pulled out a variety of chocolate based sweets. There was a whole triple chocolate cake, bought from a deli store, and almost every kind of chocolate bar available. She greedily tore open the wrapper of a chocolate bar and took a bite, the growl in her throat signaling her pleasure. The Demon Queen shivered and fell backward, her body quivering as her eyes rolled.

"That's the stuff," Chimei said briefly, taking another bite of the candy bar.

"Now then, Chimei, I have some very serious matters to discuss with you," Maou said, sitting across from his sister, who sat back up and tried to focus on Maou, though the candy in her hand drew her attention much more easily.

"Are you sure you can handle getting a job," Maou asked, "and more importantly, do you think you can trust me to train you? If not, I don't think we can have you working at the Hatagaya MgRonalds."

"But then, where else am I supposed to work," Chimei asked blankly, "no offense, bro, but the last time I let you take the lead, we lost the final battle, and had to retreat to this world."

"I know, I know," Maou interrupted, holding up his hands, "but here's the thing, my boss is interested in you. She seems to think you might be a good fit, so if you think you can handle me being your boss, then we'll begin working on your etiquette. If not… well, I guess you'll have to try a local convenience store or something."

"I hate customer service," Chimei groaned, speaking through the sweet, melty chocolate bar she was devouring.

"Consider it a temporary measure. We can rebuild our armies here, and this world's fear and despair will fuel our eventual re-ascendance to power. We just have to be patient."

Maou tried to judge his sisters feelings. The sweets he'd brought her were certainly having a positive effect, considering the fact that Chimei hadn't outright rejected Maou's proposal, still….

"What's your long term goal for this," she asked suddenly, "how many years do you think it'll take for us to reconquer?"

"Technology is far more advanced here," Maou reason, rubbing his chin thoughtfully, "but was have magic on our side. All things considered, I think we could return to Ente Isla and restart our conquest in about… fifty years."

"Only fifty years? How are we supposed to form an army strong enough to retake Ente Isla in fifty years? You forget that the humans in the other world have magic as well, and then there's the Church to contend with, and Heaven! Think," Chimei insisted, pulling out a piece of paper and a pen as she began to scribble.

Maou tried to look at what Chimei was writing, but she shielded it from Maou's eyes, drawing for a few more minutes before holding up a paper with several rough sketches. There were strategies, theories, and projected MgRonald's incomes, all of which was expanded upon further, and multiplied by twenty five years.

"Look at this, Maou," Chimei said, referring to the incomes she'd drawn up, "in fifty years, two incomes without any sort of raises will barely net us enough to buy a high end luxury vehicle, let alone a tank, or some other kind of advanced weaponry. And then, if you look here, I've made a chart to account for inflation, and another chart to measure how suspicious our co-workers would get if we didn't age! It's going to increase exponentially once we're in our five hundreds, and we don't look a day over twenty!"

Chimei flipped the paper, and there Maou saw a web chart, with Maou at the center, and surrounding him were the names of his co-workers, human associates, and even his landlady.

"Each and every one of these people is an obstacle in their own right, whether it be because you wouldn't be willing to sacrifice them, or because they are far more than they appear to be," Chimei continued, now digging into the entire triple chocolate cake with a fork as she spread crumbs all over the table.

"So that means we'd have to wait for the humans to die, and everyone else would either have to be destroyed or detained, assuming we'd amassed enough power to do either in fifty years. And finally-"

Chimei pointed to a very small graph that had been squeezed into the margins, and Maou could barely make out the words 'Odds of Defeat over a Period of Twenty Five Earth Years'. The poorly drawn graph, much to Maou's surprise, started out steadily enough, but eventually sloped upward in such a hard curve that it became vertical after almost ten years.

"Our chances of failure grow rapidly after a decade… face it, brother, this planet is a lost cause. Looking at all this, I'd almost say we should pack up and leave now."

"That's ridiculous," Maou said, shaking his head, "where did you even come up with the variables to do the math? Something tells me that your graphs and charts are just a ruse to get me to abandon this place so that you don't have to try and get that job."

"I'm the one who wanted the job in the first place," Chimei said, looking scandalized.

"A brilliant cover," Maou snickered, "but you can't fool me. You only offered to get a job as a kind gesture, in reality, you're as much of a NEET as Lucifer!"

"You take that back," Chimei hollered at her brother, the chocolate cake now completely gone.

There was a thumping on the wall that bordered Suzuno's room, and from behind it, they could hear the Inquisitor shouting.

"Quiet down, over there! People are trying to sleep!"

"You quiet down," Chimei shouted, going over and pounding on the wall in retaliation.

Suzuno must've recognized who it was, because she fell silent.

The Demon Queen resumed her seat, still fuming as her plan backfired. It seemed her stupid little brother was still familiar with her methods. Chimei smiled widely, looking terrifically evil as she leaned forward across the vanquished chocolate bar wrappers.

"Fine," she said finally, "I'll work with you. Let's get started on this 'etiquette training.'"

Maou smiled. At the very least, if his sister did something stupid while at work, he could simply get Kisaki to deal with her. It would be a showdown- no- a bloodbath, between two of the most stubborn, strong-willed women Maou knew.

He'd have to remember to bring some popcorn.

"Very well then," Maou said, taking out his own piece of paper, and snatching the pen from the table, "let's get started!"

Here's the second chapter in a challenge story thought up by misssexysmartypants, who has her own version of the story, except Maou has a brother instead of a sister! Go check it out!

Anyway, here we see Maou and his sister, disagreeing (as siblings often do) and we also cover the Demon Queen's addiction to chocolate, Kisaki's badassness, and a variety of other topics. How will Maou handle the predicament he's in now?

I honestly don't know.
