A/N: Hello and thank you very much for reading my work! This was somewhat a result of reading a whole bunch of isekai manga as well as playing Obey Me too much. I hope you'll enjoy as much as I did writing. It will initially start slow but will take off shortly. I'm also going to use one or two Japanese phrases here and there or some honorifics, but if it bothers you please let me know. Please let me know what sort of things I can do to improve, and enjoy!

Chapter 1

Have you ever thought of what it would be like if you were given a second chance at life?

I think pretty much we all do at some point of our lives. What happens after death and whatever variations of those questions are pretty common, after all nobody still knows.

The thing is… I don't even know either obviously, but to tell the truth, I died already.

Weird huh?

Well, I think so too, but it was bound to happen for me. I didn't have enough time and was predicted to die from the start. I had cancer. It sucked. I couldn't even do anything in the end because it happened so fast. I wanted to at least tell my family it would be okay and not to cry over me. The pain I felt the whole time was nothing compared to that. Being stuck in a hospital bed with tubes and IV drips all while not able to move out from my bed, I was too weak to speak. They couldn't even tell if I was able to hear them.

My name's Kaname, by the way. I am, or was, a 20 year old Japanese American guy. Right now, though? Apparently I'm a slender 16 or 17 year old high school girl. Or at least I think so. My thoughts are a jumbled mess right now, sorry.

How'd that happen? I dunno, but I had to roll with it. I don't exactly have a choice when I'm in literal hell where demons can eat me at any time. How'd that happen? I dunno, this one demon guy named Diavolo said I was summoned here or something for an exchange student program. How'd that happen? I dunno, that same Diavolo guy had this great idea of wanting to unite all three realms in peace and to do that he proposed this program, I guess.

It was really inconvenient because I was seriously in the middle of brushing my teeth. No, I meant it. I was in my pajamas right at that moment with my toothbrush in my hand. They wouldn't even let me spit out the toothpaste. Not a lot of things can make me cry, but this, this hurts me.

So now I'm a girl with not much physical stamina and I think my blood pressure's gonna go high at any moment seeing as how I was kidnapped/teleported into this "Devildom" against my will. Somehow I have my stuff conveniently packed for me, which is weird but I guess that's magic for you? I kept wishing I was dreaming, but that wasn't happening.

"Are you paying attention, Kaname?"

"Yeashr," I replied, making sure to put as much emphasis in my sarcasm as possible to give a strong hint that this was very inconvenient and I'm not too overly thrilled. He totally ignored it.

This man, calling himself Lucifer, the Avatar of Pride, seemed to be a pretty uptight guy. I could imagine him right now with stacks and stacks of paperwork and multitasking on the latest smartphone. Actually he probably wouldn't have any paperwork lying on his desk and his work area would be likely pristine and all and he'd be on said desk doing more work because that's how he kills time, with productivity. Well Diavolo called him his right hand man, so he's gotta be one of those superworkers. All that's missing is some glasses for him to tilt and smirk all intelligent and pompous.

"Very well. This is your D.D.D. You will find that it functions very much like the smartphones in your world," Lucifer handed me the phone gently in my palm. "You will be taken in under the watch of my brother Mammon. He's… Well…"

Based on his hesitation and him twirling his long dark soft looking bangs in thought, I'm guessing I should be worried.

"He's scum."

Ah, there it was.

"The scummiest of scum."

Ok.

"The scummiest scum of scum."

Then why the hell are you putting me under his care?

"Well, go ahead and give him a call to introduce yourself."

Don't wanna.

Lucifer looked at me with obvious expectancy, quirking an eyebrow as if telling me, "Well?"

Fine. I whipped out the D.D.D. while being sure to send a rather rebellious look at Lucifer and searched up Mammon in the contact list. Then I waited for the phone call to go through. All while that's happening, some toothpaste started to drip from my chin.

Once I heard the call pick up, I was prepared for the worst.

"Yoooo."

I paused for a moment, then decided to greet back, "Yoooo." It came off a bit gurgly, but I think I got my message through. So far so good, right?

"Are ya foolin' around? Who the hell are ya?"

Dear god, it was so tempting to just shout back 'Your mother!' but I resisted.

"I'm a hooman." Thinking back on it, I didn't want to talk much and there's the fact that I still wasn't allowed to spit out the toothpaste froth in my mouth. Maybe I should just spit at Lucifer anyway. Or Diavolo. Heck maybe everyone here. I mean they're the reason this is happening and they honestly can't blame me.

"Whaaa? A human? Geez I was gettin' chilly here thinkin' it was Lucifer again. Ya should've told me right away. So what business does a human got with THE Mammon?"

Did he just reveal to me his Kryptonite? Must make a mental note of this. "Lesh be friends," I replied carefully. Better to be nice than to piss off any potential predator, right? Plus this guy's gonna be my partner or whatever.

"Eh… What're ya even sayin'...?"

Was the toothpaste froth messing with my speech so much? I'm trying my best here.

After a bit of back and forth talking, it sounded like it dawned on the guy that I'm the other human exchange student. Good luck with that, he basically said. Oh no, he wasn't getting off that easy. If I have to suffer, I'm taking him down with me.

"Looshifuh called fo' you," I shot back. Oh yeah, I'm throwin' down the Lucifer card and he can't stop me. If that demon was his weakness, best exploit it. My survival's on the line here, you know?

He tried to call my bluff. Unfortunately Lucifer was standing right next to me hearing everything.

"You've got 10 seconds… 9… 8..."

"YESSIR!"

Damn… Lucifer's good.

And with that, the call disconnected and I'm left staring somewhat stupefied at my new D.D.D.

"Sounds like you had a nice chat," Lucifer stood there smiling with an all too knowing look obviously enjoying my pain.

"He sheems reliable," although I was sarcastic, I was not going to let the guy have the satisfaction that I would've preferred him.

"...You really think so?" Lucifer's smug smile curled down into a frown. Wow, he really seemed disappointed, or was it just me?

"Well, if you were suddenly brought to a strange place and then get told that an unfamiliar face will now take care of you, you'd certainly feel anxious."

No, I'm anxious because I still can't spit out this toothpaste because You. Won't. Let. Me. And. I'm. Dying. If I swallow, does the Devildom have a poison control center?

Finally it looked like Diavolo took notice, widening his light orange eyes, "Oh my! It looks like we really brought you here in such a bad time!"

No kidding!

"Why, you're in your pajamas!"

Yes!

"And you're clearly tired!"

No! Well yes, but that ain't it, chief!

"Would you like to go to the restroom for a moment?"

I nodded my head rapidly. Yes, yes, yes!

Diavolo laughed as though he was witnessing something adorably charming and not a freakin' human being clearly on the verge of dying inside.

Lucifer sighed, "Yare, yare. Come with me then."

Oh thank almighty Diavolo, I will never doubt you again! I barely could hide my excitement as I zoomed in immediately in the restroom. I think Lucifer was damn near to shock that he clutched his chest as though he was about to have a heart attack. Actually he seemed to do that a lot.

After I cleaned up, I took a moment to stare in the mirror. Diavolo wasn't kidding when he said I looked like I needed sleep. Dark circles were formed under my baggy green eyes. My medium long pink streaked black hair was messy as hell. I had pajamas on of course, with some bunny slippers and my luggage had the rest of my clothes despite being so small. What kind of delivery witchcraft service is this and why didn't we have it in the human world?

I then had to take a moment to really let it sink in. My name is Kaname. I'm a 20 year old college student that was a cancer patient and passed away, I'm sure of it. Then I suddenly "woke" up as a girl. I even checked "there" just to be sure, and my "best friend" is gone. Sayonara. My body is a girl's, through and through. I think guys sometimes think of scenarios like this and usually say that they'd take advantage of their new bodies or something. Since it's happened to me, I realize I'm just not interested because it's me, and that's pretty boring. I do have to say, I make a pretty cute girl though.

I tried thinking up many different possibilities. Was I reincarnated? If so, why wasn't I reborn as a baby? I had no memories of a female childhood, just of my life as myself up to now. This was all too weird, but I had to roll with it. I had no intention of dying a second time, plus in the off-chance that I could see my family again, I'll need to keep going.

With renewed vigor, I splashed the cool water in my face and came out feeling refreshed. Even Lucifer seemed to have noticed my good mood and commented approvingly.

"Ah, Shouldn't you want to get changed? We wouldn't want you to continue through the formal process without looking presentable."

As I expected, he is super hella nitpicky. I sent him a look indicating that I don't wanna and I'm comfortable being in my pajamas.

He sent a look back. The look that said I'll be dead if I don't cooperate. Fine.

I went back inside with a dejected look while Lucifer smiled in satisfaction.

I was introduced to some of Lucifer's brothers that I'll be staying with. One guy was Asmodeus, the Avatar of Lust. Another was Satan, the Avatar of Wrath. The third one there was Beelzebub, Avatar of Gluttony. They weren't exactly hiding their seven sins theme much, were they?

Asmodeus in particular seemed pretty dangerous despite being a cheerful happy go lucky flamboyant character, or at least that's the vibe I got from him. My instincts told me that I would be sent to a dangerous world if I let him do what he wants with me. He tried doing some testing by challenging me to a staring contest, but I totally won. At least I think I did. Apparently he was trying to charm me or something but it didn't work. If it did and I fall under his spell he'd eat me, so said Satan.

Satan felt like the most normal, but knowing he's the Avatar of Wrath, I'm better off not risking to blow a fuse. I felt that the apocalypse would start if anything ticked him off. He seemed to pride himself on being knowledgeable and giving me basic info on himself and his brothers.

Beelzebub was a pretty ripped guy, really tall too. He seemed kind of nice, just a pretty big hungry dude. Still his stomach growl was pretty inhumane, do all demons have those?

After some more explanations about the Devildom world, I kind of got the gist of the general environment. While most demons agree with Diavolo, there's some that don't and would probably eat me. So these brothers are going to lend their protection to me since I'm a special case. Joy. Except these brothers can also eat me or kill me. Still Lucifer assured me that he'd do everything in his power to make sure Diavolo's wishes are granted, thus my protection is set.

That's all fine and dandy, but I still wasn't too keen on being in this world in the first place and wanna go home. "Oi, when do I get to go home?"

"Ha ha, what an interesting human you are. You'll be staying here for a full term of one year. Don't worry, such days will fly by before you know it, just be sure to do your tasks as promised," Lucifer stated, lips curled in a knowing smirk.

I swear to god, these guys are infuriating. Why the hell do I even have to do this? Do I even get a choice?

Diavolo, not able to read the tense mood, happily offered to send a text so that I'd have his contact as well as the rest of the guys there.

I never really sent texts much, just small messages like "need fruit on sale," or "I'll drive sis home today." These guys use it like a chat system. Also imagine my surprise seeing stickers. Huh. Cute, I guess. I've never used those.

At that moment, the hallway bursted with yelling as a figure zoomed all the way over to us and I'm suddenly face to face with a very angry tanned platinum blond man glaring daggers at me. Before I could back up, he started shouting in my face.

"HEY! Just who do you think you are, human? You've got a lotta nerve summoning the Great Mammon! Listen up, because I'm only gonna say this once. If you value your life, then you'll hand over all of your money now! And anything else of value, too! Otherwise I'll wipe that stupid, happy-go-lucky look right off your face… by eatin' you! Startin' at your head and working my way down, until-"

"Mammon, shut up or I'll punch you!" roared Lucifer, who proceeded to punch him anyway.

I didn't know whether to be shocked or impressed that this Mammon guy managed to get all that out in one breath.

Mammon yelped in pain and protested the unfairness of his injury while I took the opportunity to scoot further back.

Satan, being ever so helpful, piped up, "Kaname, Mammon is the Avatar of Greed. He governs and oversees all forms of it. Whenever he takes a liking to someone, they suddenly find themselves awash in money."

Oh sweet!

"But from what I hear, if he decides to break it off with someone, that wealth evaporates. They're left without a Grimm to their name."

Oh no, not sweet. Wait, what's a Grimm?

"And he's also a masochist. That part's important," added Asmodeus with a clearly gleeful look on his face.

Wait, why does it matter? There's no shame in kinks, but isn't that private?

"Y'all, stop telling lies! I ain't asked for that punch, and I AIN'T a masochist!"

I dunno who to believe, but I didn't even care anymore.

They started bickering over me since the guy who's supposed to be taking care of me didn't want the job. Me neither, but I just wanna live.

"What about Beel?"

"We might as well tell Beel to eat Kaname if we put her under his care."

Beelzebub nodded in agreement, "I can't guarantee I won't do it."

"Ugh!"

"Give up Mammon and do your job."

"I hate you guys! Every last one of ya! Fine!"

I felt dead inside. Why couldn't I just go home?

"Alright, human listen up," started Mammon seriously as he glared at me once more, "As much as I don't want to look after you, I've got no choice. But in return, you better make sure you don't cause me any trouble, got it?!"

I nodded, "Alright, deal. That's fair."

"Good, that's what I want to hear. As long as you do as I say, we won't have any problems," Mammon stated in approval, running a hand through his white puffy locks of hair in frustration.

I nodded again in agreement, but then paused, "Uh wait a sec, since when did I agree to just listen to y-"

"Just be sure you don't forget which one of us is the boss here," snapped the demon as he turned away to grumble to himself.

Lucifer, satisfied at Mammon's resignation to his fate, turned to me to offer another explanation on what my task was. "You are to polish your soul nicely and to acquire the power to resist demons."

Wait. What?

The black haired demon went on to explain the basic idea. Demons like good souls and will do anything to tempt the human and obtain it. Other students at RAD (If I wasn't in a god-help-me-out-of-this situation, I would've chuckled. Best acronym ever.) have tasks too and so either I get out with a great soul that can resist demon temptation or they tempt me.

I'm summoned here to become someone's lab rat. Whoo.

"There, there, don't give me that look," sighed Lucifer shaking his head, "You'll be having the assistance of me and my brothers after all since you have no magical capabilities. To recap, these tasks will consist of dance battles and we will lend our power to you."

I perked up at the phrase, "dance battle." Like Dancing with the Stars? So you think you can dance? DDR?!

...Nope.

At first I got kind of excited thinking I'd be able to do something like DDR or Just Dance or something to that degree. I was ready to Pump it up and Dance Rush Stardom and Dance Evolution and stuff. Or maybe even like Elite Beat Agents! At worst it'll be actual dancing and I'm not really that great, but hey, dancing's fun, I'm willing to learn. In reality the process was more like I'm coordinating the demons and they're doing the dancing against other demon opponents and stuff and I'm cheering them on with glow sticks. I still don't get the point but whatever. So what if I don't get to show off my high score playing Waka Laka or Din Don Dan? I'm not sad at all…

"Oh dear, Kaname-chan is crying, poor thing!"

I wanna go home.
