trapped in obey me

prologue

Im in math class right now taking a algebra pre-test so my teacher could see what i know. Ofcourse i failed miserably so i just closed my i pad and went did some work on my upcoming book project and went to sleep because my math teacher is a pretty chill dude and doesn't care about what were doing as long as its quite and within school rules.
But right after i fell asleep i noticed that i was no longer in my chair because I couldn't feel the cold metal bars against my calves.
After blinking a few times i got up confused as fuck but when I took i just saw seven dudes who looked to be twice my age just staring down at me. The one in the middle who looks burnt af started to talk but i just plopped back down and went back to sleep. Im to tired to deal with this bullshit today.
But ofcourse there was an eighth one with green hair who could probably pull off a sebastian cosplay ngl. He pulled me back onto my feet but i just refused to move because i am obviously in denial about this right now and simply don't want to exist.
The green haired guy asked me if i was ok and i replied "im sleepy, let me go back to sleep", but the black haired guy replied "you be able to sleep shortly but for now just try to stay awake". And ofcourse these guys got the most vulnerable persons life in there grasp they could just gently breath at me and i would pass away. At this point compiling with whatever demands these weridos have is probably my best chance at escaping. So i took my 1/4 filled bottle of watermelon mountain due and chugged what was left then slapped my cheeks to wake me up.
I then stood straight up to give them my full attention and then rhe burnt red-head started to talk again. "Welcome to the devildom karisu. Sorry for the earlier shock if we gave you any. As a human it will probably take a while for you to adjust to your new surroundings" he said that very loudly it kinda hurt my ears to but i was to scared to say that. "Is this a dream" i asked kinda hoping that it was. After all i had a goddam reading test to take and i actually give a shit about my English and nath grades.
He then replied with "what a very human thing to say" i wanted to reply "bitch you human too" but then i remembered he said were in hell and any one of these guys can snap my neck at any given time so i just didn't. "Outstanding. I think you might be just the person we are looking for. I suppose i should start introducing myself, im Diavlo i am ruler of all demons and all of them know me. And some day i will be crowned king of devildom"
He then brought me to a nearby balcony where we saw a huge black castle like building surrounded by millions of tiny buildings. He then pointed twoards the castle and said "this is the royal academy of diavolo, but we just call it RAD. We are standing in the assembly hall the very heart of RAD. Im the president of the student council"
after he finished talking i asked "when can i go home" then a black haired guy came fourth and started to talk. "I will explain all of that to you" divalo then said "karisu this is lucifer. Lucifer is a demon and the avatar of pride. He is also the vice president of the student council and my right hand man. And not just in title i assure you. Beyond that he is my most trusted friend" and with that lucifer replied "flattery will get you no where diavolo. Speaking on behalf of our great students i give you a heart felt welcome karisu"
"On behalf of the students??" I asked. Surely someone has enough sense that i need to go back home because I HAVE A FUCKING DOZEN QUIZZES TO COMPLETE. And ofcourse the Lucifer guy started to talk again. "Diavolo believes we should start strengthening our bond with the human and cellistal realms, and an efficient way to do so would be a foreign exchange program. We sent to students to your world and two to the celestial realm then two angles came here and two to earth and then two humans came to hell you being one of them. This program will last for one year and then you will give a written report about your time here". I then calmly replied with "WRITE A PAPER?!?!?!?!??!?!?!??!??!?!???!?!??!?!??!?!??!?!?!?!??!?!?!?!??." and he replied "just a small one paragraph essay not a whole entire book. You can take it easy. And don't you worry i will not leave you to fend for yourself here. You need someone to look after you and i think my brother mammon would be perfect for the job. He the avatar of greed ..... how should I put it? Oh well you will understand soon enough. Here take this, it's called a D.D.D and is extremely similar  to smart phones in your wrold and here's a charger to go with it. This is yours to use for the remainder of your stay. Now go ahead and give mammon a call with it" he said dropping what did indeed look to be a phone and a wire in my hand.
