Chapter 1: A new arrival
Chapter Text
It was a normal day for Nagisa, it was a warm spring morning when, as he was trekking through the forest up the hill. He was alone, which, fair it was very early and most students wouldn't be here until later, so he just enjoyed the scenery , what Nagisa did not expect was a portal to appear under him and just like that he fell through it.
.
.
.
It was a peaceful day in the netherworld, well as peaceful as it gets in the Sullivan household. Opera was helping their master organize files and put them away until they saw a glowing purple portal outside the window, and saw somebody a child fall to the ground.
They of course being Lord Sullivan's security devil, ran to the garden to investigate the intruder, after all, you can't be too careful in the netherworld, especially when your young master is a human.
<When they arrived in the garden, they saw a teenager with light blue hair, clothing that you couldn't possibly get in the netherworld, and deep blue eyes that reminded them of a certain young master, that was currently at Babylis. The boy who couldn't be more than 15 was passed out on the ground, but what do you expect when you see a teenager fall from at least a 20-meter fall. Opera was hesitant at first, but eventually caved and bought the teen inside, after all children were a treasure in the netherworld.
.
.
.
Nagisa woke up with a nasty headache, he remembered falling through a portal and-
he shot up realizing he was lying On a couch. Who brought me here? Nagisa thought, turning his head to the right he saw what was essentially a 2-legged cat with red hair in a braid. The cat must have felt him burn a hole in the back of their head with the way Nagisa was starting.
Turning around he could see the cat butler?(can this cat even be considered a butler, I mean they got the clothes so maybe???) blank expression, and in the most monotone voice Nagisa has ever heard asked:
-What is your name, and how did you get here?-
Wow they did not beat around the bush huh
- I'm Nagisa Shiota, and I'm pretty sure I fell through some purple portal. All I knew was that I fell through the ground, and now I woke up here. Actually, where am I?This is so confusing. What is going On? I just wanted to go to class.-
-Well then, Mr. Shiota, I must inform you that you are currently at Lord Sullivan's mansion, and I already contacted my master about your... less-than-expected arrival.So I highly suggest you stay put until then.- The cat butler spun on their heel and left the room, leaving a confused Nagisa still sitting On the couch he woke up on.
This has to be some weird dream... right?-
.
.
.
Opera wasn't sure what they were to do with the teenager who was obviously a human child. How did a human child get here? What should they do with him now that he's here? Are they gonna need to inform border control of this?- Those were some of the questions running wild in ther mind.
.
.
.
When Sullivan received a message from Opera about a human child falling from a portal into their garden, he thought the red-haired demon was messing with him, after all, human children don't just fall from the sky.
But Opera's voice was serious, no lilth in ther voice. Sullivan was wondering if the child Opera was describing had something to do with his recent trip to the human world again...
.
.
.
Somewhere in the netherworld in the base of operations of the border control, there sat Henry Azazel, with his head in his hands as he sight in defeat. His head was killing him, and the report of Sullivan going to the human world AGAIN didn't help at all.
Chapter 2: The first impression.
Summary:
This is basically the chapter where Sullivan, and later Iruma will meet Nagisa.
Ooooo i wonder what Sullivan will do when he sees the blue haired boy. ;)
This will also explain how Nagisa ended up in the netherworld.
Chapter Text
Sullivan was quite puzzled at the unexpected turn of events, I mean who wouldn't? Your security devil just informed you that a human child of all things fell through a portal in the sky. He knew Opera wouldn't joke about something like that, so after he finished wraping up the work at Babylis, he flew straight to his estate.
Opera welcomed him at the door, opening it wide.
-Welcome back Lord Sullivan." They greeted in a monotone voice.
- Hello Opera, i recived your message and I must say that is quite a story." Sullivan said in a energetic voice.- May you lead Me to our... unexpected guest?"
-Of course, please follow me." They noded curtly and spun on their heel.
.
.
.
Nagisa was still in the living room- (at least he thought that was supposed to be a living room, honestly you never know) sipping on the "hell grey tee" the cat butler who he later learnt was called Opera gave him. He wouldn't say he was relaxed, after all he didn't know whether to trust the red haired cat or not, neither was he somewhere he reconized, so he couldn't relax or drop his guard yet.
Not to mention the fact the cat Opera said they contacted their Master.(he honestly didn't want to know what that implied) So it was hard to say he was relaxed.
Soon enough he felt a powerful presence that made him want to curl in on himself.
But he tried to calm down, it wasn't easy but he persisted. By that presence he deducen the "master" must have arrived,
he did not look forward to meeting him.
.
.
.
Sullivan enterd the living room to see a blue haired teenager sitting stifly on the couch, upon sensing his uneasyness he tried to suck in his aura so he wouldn't freeze the teen completly, after all they still needed awnsers.
He sat across the boy on another couch, with Opera dutyfully behind him.
- so what is your name child?" he said as gently as he could after all they didn't want to scare the teen too much.
-My name is Nagisa Shiota." Nagisa said as calmly as he could.
Sullivan was slightly taken aback after hearing his surname. (could it be that the contract was completed only now?)
-Nagisa is your mothers name perhaps Hiromi Shiota?"
Nagisa startled at the mention of his mom he didn't know what to do, lie and say no? Tell the truth and say yes? He didn't know. Finally he pulled himself together and decided to awnser the tall old man.
-yes she is my mom, but... how do you know her?" Nagisa asked hesitantly.
-You see Nagisa your mom sold your soul to me 9 months ago. In exchange for a baby girl. And it seems that the transaction only took place now that the child was born." Sullivan said carefully.
Opera was shoked for the first time in a long time, ears pressed close to the head, tail stiff as a board. (another one? someone sold there childs soul again? just to have a child of the gender they wanted?!, despicable, those human don't deserve the joy of having a child.)" they tried to school there expression as quickly as they could.
.
.
.
Meanwhile when Opera was having a internal battle... Nagisa was... simply shook. How can he not? He just learnt his own mom(should he even call her mom after she sold him?) sold his soul to a demon in Exchange for another baby, a girl this time.
Was he so much of a disapointment to his mom that she decided to start over again? Was it something he done that he didn't know about? Did he somehow displease her in some way? Why did she sell his soul? What is he supposed to do?...
Nagisa felt his vision get more and more blurry, he didn't even realise he was crying untill he felt tears fall on his pants. Why couldn't he control his emotions, why can't he stop crying, the tears just kept coming.
Sullivan felt pity for the young boy, its not exactly easy to come to terms with the fact that your mother caregiver kin sold your soul to a powerful demon. So when the boy started crying slightly curling into himself, Sullivan made a decision right then, and there that he was gonna adopt the boy.
After all it was a win-win for both of them. Nagisa would gain a family that loved him for who he is, and Sullivan would gain another grandson he could spoil!
He could already see a pair of 2 blue haired boy calling him Grandpa as they smile his way. Oh he was so gonna make the other 2 greats jelous that he had 2 grandson's while they had only 1.
But first things first, he would have to make Nagisa his future grandson stop crying. And what better way to do that then asking Nagisa to be his grandson!
.
.
.
Nagisa felt a large hand be placed on his shoulder, he flinched and the hand let go.
He looked up to see who it was, and as it turned out it was that tall demon his mom Hiromi sold his soul to.
-Say Nagisa would you accept to be my grandson?" The Old man said chearfully
...
-huh." Nagisa was beond confused, was was going on, how was he supposed to respond to that. He was a mess of emotions currently, so his mind was completly blank at the moment.
-Oh you see i already have one grandson, and as i want my grandson to have somebody he has something incommon with you would be perfect, also i wouldn't pass up an opportunity to get another grandson!" Sullivan was practicaly vibrateing on the spot.
-I have something incommon with your grandson? but youre a demon arent you so your grandson must be t-"
-Hes human too yes!" Sullivan interupted
Nagisa yet again was shoked, just how many twists is this old man gonna reviel!
-i still don't understand, why would you want me as your grandson? Nagisa wasn't sure if he could trust the demon yet after all who knows what the old man is capeble of..."
- Hmmm? I thought i gave you reason enough? But it really is as simple as 'i just want to'"
-Are you sure?"
-Absolutley!"
-...... i guess it can't hurt to accept..."
-YUPIIIEEE, OPERA I HAVE ANOTHER GRANDSON PLEASE PREPARE A ROOM FOR OUR LITTLE NAGISA!" Sullivan practicaly screamed his lungs out. ("little nagisa?)
- Of course Lord Sullivan." Opera moved at a high speed to complete the task there master gave them. (Wow i forgot they were still here-" thought Nagisa)
-Now than! Please stamp this form!" Sullivan Grandpa? said as he gave Nagisa the adoption form.
Stamp
.
.

Iruma was walking home, Clara and Azmodeus have already split off to go home. He approached the gate, and went inside, to his suprise Opera wasn't there to greet him, but he brushed it of as they were probably doing housework. Ali on the other hand was suspicious, Opera was always there even if they were busy, so it of course rubbed him the wrong way.
Next thing Iruma knows is his Grandpa practicaly flying dow the stairs to him.
-Oh my darling Iruma i missed you so much!" Sullivan said crying hugging the boy close.
-i missed you too grandpa. Iruma relaxed in his grandpas hold.
- Oh i must inform you that I have a present for you~!" He said in a sing-song voice.
- huh?" Iruma was confused (prezent what prezent??)
- Oooh Nagisa! Come down!~" Sullivan said in a chearfully tone.
Iruma heard feet pounding on the floor, and thats when he saw him
A boy about his age, with light blue hair and eyes. They both stared in shook at eachother, not moveing a cm.
-Iruma, meet Nagisa! He is your new brother, so get along you two~!"
-HUUUH!" Both Iruma and Nagisa yelled at the top of there lungs.
Chapter 3: Sooooo..... You're my new brother?
Summary:
A chapter of Iruma and Nagisa bonding over trauma, + Ali ( I think this is more fluff than angst-).
Next chapter Nagisa meets balam + fluff.
Notes:
Hello i must inform you all that for the forseable future i will not be able to post.
Tomorrow is a 4 day long field trip with my class,
than work from 09.30 to 10.25, so I'll try to post as much as posible but updates will be slow :(
Chapter Text
Iruma, Ali and Nagisa both sat on a bed in Irumas room (Opera was adding finishing touches to Nagisa's room).
Ali was still suspicious of Nagisa, the boy just triggerd that one part of his brain that kept telling him to RUN, it made him shiver. The boy wasn't normal thats for sure.
-Soooo.... you're my new brother huh." Iruma said awkwadry, well can you blame him? Put yourself in his shoes, you come back from school exhausted after the quiz that Kalego made for them, AND HALF THE QUESTIONS WEREN'T EVEN MAKEING SENCE!(is this becouse Opera used a summoning seal recently? JUST HOW SPITEFUL CAN YOU BE?!). So you would think he'll have time to relax at home but the first thing that happens is your grandpa telling you, that you have a new brother, and practicaly shoveing you in a random room to bond.
-Yea.... it would appear so-." Nagisa was..So...so confused. He was still trying to comprehend that he had his soul sold to a demon, and that the same demon adopted him not even 10min after he met him.( like WHO does that?!). So sue him.
-... So are you gonna adres the situation or keep silent??" Ali asked imapatiently. He was so sick of the two blue haired children just stareing at eachother,( is this normal for humans or What??) . That seemed to do the trick as both boys now turned there full attention to him. ( Oh sweet Delkira there stares are so scary-) - Hey stop stareing at me and... Idk talk about you're family life or something!? JUST STOP STAREING AT ME LIKE THAT!" Ali screamed panicked.
-like what?" Both Iruma and Nagisa said in unison. -Jinx!" they both exclaimed.
- is this a human thing or...?" Ali asked.
- no not really, at least thats what i think." Iruma said hesitantly.
- No, you are right Iruma." Replyed Nagisa.
- But i think Ali is right, we should talk about our life before we were sold here, after all we are brothers now." Iruma said nervously. He might as well try to bond with the other blue haired teenager, I mean how hard can it be?
-Wait you were sold here too?" Nagisa was shoked, (someone else was sold to Sullivan Grandpa?)"
- yeah.. my parents sold my soul to Grandpa for money when i was 14, what about you?"
-my mom, it feels wrong calling her that now. But she sold me to have another child, a doughter this time..." It was hard for Nagisa to speak about it after all he was still procesing it. He still didn't get it, why, why? He was snapped out of his thought when he realised that Iruma was holding his hand.(it was both soft and warm... it felt nice).
- Hey its ok i understand that its hard, especially when it happened not too long ago, you must be tired and confused, take your time, and when you're ready we can talk about it again." Iruma said simleing at him, holding his hands tight, It was a while since he was able to tell someone how he really felt. He thought he might just cry again.( out of the corner of his eyes he saw Ali dissapear into Irumas ring to give them some privacy)
- I can start if you want." Iruma said.
- no its ok, I'll tell you but I can't promise that I won't zone out." Nagisa was a nervous wreck, and still raw from all the tears from before, but he will try after all, he told Iruma his brother that he'll tell him, so he was gonna follow through with that.
- So from as long as I can remember it was always my mom and me, I never really knew my dad, but I did see him in some old pictures at home. From what I remember he had really short blue hair, dark blue eyes, and in the picture he was in a yellow button up shirt, his hair was slicked back, and that picture was of him standing next to my mom holding me as an infant. Also-" Nagisa didn't get to finish as Iruma interupted him.
- Wait! did youre dad wear glasses when he was reading or in any of the photos was he wearing a pair of red glasses by any chanse?" Iruma asked a little uneasy ( surely I'm wrong, I know my parents werent the Best but infidelity?) Iruma was praying to whatever God was there that he was wrong.
- Huh, ye he did have glasses in one of the photos thought it was older than most of em-. Why do you ask?" Nagisa was yet again confused, why would Iruma ask him that- ....... Wait.
- Hold on don't tell me that..!" Nagisa shouted.
- I think that we are..! Iruma shouted as well.
-THAT WE ARE BLOOD RELATED!?!" They both yelled. It was a miracle that none of there guardians came rushing in at the sound of the boys screaming.
- WOWOWOWO OK TIME OUT WHAT DID I JUST WALK IN ON?!" Ali screeched. He dissapeard to give the newly acquainted brothers some space, but he got bored so he decided to come out. WHAT HE DIDNT EXPECT WAS THAT THEY ARE ACCUALY BLOOD RELATED!! Wow there parents are really all scumbags.
-i didn't expect that we were blood related, ot to find out about it like this." Nagisa commented. It will definetly take a long time for him to wrap his head around this.
- Wow I... don't know what to say. Also sorry for interrupting you." Iruma apologized, lowering his head.
- its ok I dont think i want to continue anyway, thanks for the interuption it helped me get my mind off the fact that I was sold." Nagisa knew he sounded weird, but he really didn't want to continue.
- Alright than i won't push for more. I guess its my turn now than.. haha..." Iruma was getting nervous, he never really got over his parents selling him, yes he did tell Profesor Balam, but thats becouse he accidentally spilled the information (just like the fact that he was human), but it still stung like a burn, no longer fresh and raw, but now slightly heald but still stung. He didn't know if he was ready to tell Nagisa all of it, after all they only knew each other for no longer than 3h. As Iruma was spiraling, Nagisa picked up on it.
- Hey theres no need for you to tell me. we both went through something traumatic, and I know its not an easy thing to share. So just like you, I'll wait untill you're ready to tell me." Nagisa said giving Iruma a reasureing simle, and a pat on the back.
- Thank you Nagisa." Iruma said grateful that Nagisa didn't push and instead tried to change the topic.
- No, thank you Iruma, it was a while since i could shere my real emotions with some one." Nagisa smiled brightly.
-Ahhhh brotherly love, one of the finest things in the netherworld~." Ali exclaimed.(i totally forgot he was here)
- Ah! Ali i forgot you were still here!" Iruma screamed (i can't belive i forgot Ali was still here)
- HUH!? WHAT DO YOU MEAN YOU "forgot"?!" Ali all but screamed. - HYMPH, WELL IF YOURE GONNA TREAT ME LIKE IM NOT HERE I MIGHT AS WELL RETURN TO THE RING!" Ali said as he was going back inside the ring on Irumas finger.
...
- Soooo..." Nagisa started.
- Well I'm kinda tired, what about you?" Iruma asked, his eyes slowly closing.
- Yeah.. I am kinda tired."
- Than lets lay down and stay like that for a moment Hmmm?" Iruma asked tiredly.( man this day was full of suprises)
- Well sweet dreams Iruma." Nagisa said patting Irumas head.
- heh... thanks....... Nagisa...
Soft snores sounded through the room.
- huh, he relly must of been tired to fall asleep so fast huh?" wispered Nagisa as to not wake up the sleeping boy his sleeping brother. - Might as well lie down too."
.
.
.
When Sullivan enterd his grandson's room to ask if he has seen Nagisa ( Sullivan upon noticing that Nagisa was no where to be found Absolutley freked out, and was running around the mannor like a headless chicken.) The sight of his two grandson's sleeping on there side's, curled up with eachother, soft snores could be heard.
-Aaaaaa they look like a pair of kittens!" Sullivan whispered. - Opera get the camera and take as many pictures as you can!"
-Of course Lord Sullivan."
Chapter 4: THERE IS ANOTHER HUMAN!?
Summary:
Balam meets Nagisa
Notes:
I Know its short and all but I didn't have a lot of time. My creativity is dead 🥲
Chapter Text
When Opera called him saying they have a new human young master in the mansion, he didn't want to belive it.
(Another human!) Balam thought he was dreaming. I mean can you blame him? Imagine you study imaginary creatures, and somebody said that the species that was thought to have only one speciment, now has two.
So of course he asked for permission to come and meet the new human.
.
.
.
Shichiro arrived at the Sullivan household shortly after being allowed to visit. He was so excited he could barely stand still. But he was also nervous what if the human was scared of him?( well that wouldn't be a first) How would he react to another demon aside from his Senpai, and Lord Sullivan? How diffrent is he from Iruma?
His thought process was cut short as his Senpai opend the door and told him to come in.
- Its nice to see you in good health Shichiro." Opera said leading Balam up the stairs.
- like-wise Opera-Senpai."
Upon walking up the steps the cat butler lead him to a double door. Knocking before peeking inside. - Young Masters, you have a guest."
- huh, who is it Opera?" Irumas voice was heard from the room
- Its Balam"
-Ooooh, right Nagisa you havent met Professor Balam yet!"
(Ah. So the humans name is Nagisa).
- Huh? Who's Balam..?" From behind the door he saw a light blue haired teenager peeking his head out side.
(WTF HE IS HUGE) nagisa internally screamed). The teen had deep blue eyes, and looked very similar to Iruma.
-Hello, Nagisa was it? I'm professor Balam Shichiro, I teach students about imaginary creatures." Balam said extending his hand to the small human.
-Ah, I'm Nagisa, the pleasure is all mine Professor." They shook hands. Shichiro was ecstatic, that he got to touch another human. Unlike Irumas (Irumas hands were rough from all the work his parents made him do), Nagisas hands were smooth, it honestly baffled Balam how different the two humans are even though they look almost the same.
- Umm.. Professor if you don't mind me asking. Why are you here? Did something happen?" Don't get him wrong Iruma doesn't mind his teacher being here, he enjoyes his company and all... But why was he here?
-Ah! Right, Opera-senpai told me about the member of your household that was a human so i had to check it out, you know with me being interested in studying humans and all.." The large demon said scratching the back of his neck.
- You are interested in studying.. humans..." He didn't quite trust this guy yet but since Iruma trusts him, than Nagisa has no reason not to.
- Yes! I was wondering how diffrent you're experiences are, the diffrences between you're habbits, how diffrently you two grew up, I want to know everything you're willing to tell me!" Shichiro could barely control his excitement, two humans! Two! The amount of information about the human world he could get his claws on just doubled!... But he should ask Nagisa if he would help him with research first...
Wow this guy is certantly ecstatic." Nagisa thought.
- Of course that is if Nagisa agrees to it. I wouldn't want to force you to reveal anything you don't want to." (huh he's quite considered") thought Nagisa.
- I guess that if you just want the information about the human world, than I lend a hand."
- T-Truly?! Oh thank you! I'm sure I'll be able to make a brake-through in my research with your help in no time!"
Iruma smiled watching the interaction between his teacher and brother, he was glad they were getting along. Opera left a while ago to make dinner ( no they didn't, he just doesn't know where they went.), Iruma decided that it would be better to go inside the bedroom than stand talking in a doorway.
.
.
.
The three of them were sitting On the floor, well at least Balam was. The two humans were sitting in there teachers lap, and being gently pet by the demons large hands. It took Nagisa by suprise at first, but with time he allowed himself to relax in the Shichiros hold. At some point He even draped his wings around them in a protective manner. At somepoint Nagisa felt so relaxed he ultimately fell asleep.
- Ahhh.. now that you explain it, it is starting to make more sense to me!" Balam was happy to get more awnsers about human culture. -What do you think Nagisa?"
...
- Nagisa?" He asked confused, (huh did he fall asleep?). Now that it was quite he could hear soft snores coming from the human boy.
- Heh. He must really feel safe to fall asleep so efortlessly." Iruma commented, his own eyelids heavy.
- Safe?"
- Yeah. Its far easier to fall asleep when you know you're safe from danger, especially if you're somewhere warm and soft." Iruma was feeling sleepy all of a sudden, maybe becouse he was safe with his teacher and brother around, or maybe it was just so comforting to be pet and held close? He didn't know, but that wouldn't stop him from falling asleep, his brother a comforting weight next to him. Maybe he could go to sleep for a few...
Shichiro just sat there, two human children sleeping on him. It was quite adorable, they looked just like a pair of hell-kittens! For a second he thought back to irumas comment about falling asleep easier when they feel safe. It made him happy that both humans felt safe enough with him to fully lower their guard around him.
.
.
.
Opera opend the door to a sight of the gargoyle of Babylis, and there two young Masters asleep clinging to his Kouhai.
They secretly took a picture to print it out later and put it in there picture book.
Chapter 5: A new classmate
Summary:
So basically Nagisa joins a class of demons, and makes a new friend. And in the faraway border of the demon world, a suspicious boy with red hair, enters and " put's to sleep" some border control personel. :)
Notes:
minor mention of blood, but its impossible to write an assassination classroom fanfic without atleast a little blood
Also! Henri is only here so I can bully him! :DDD
Chapter Text
It was a new day, as it turns out Irumas Bird clock (honestly what the living fuck is that) was in fact loud enough to be heard over in his room. Makeing Nagisa shoot up from his bed in a panic.
- I swear that thing will give me a heartattack". Nagisa said trying to even out his breath. - What time is it?". Nagisa squinted his eyes to see the numbers on the clock on the wall.
6:66am
What the fuck. How can a clock show this hour. Well in the netherworld the also have a 13th month so why is he so suprised
- Goodmorning young master." Opera said entering the room. - Breakfast will be ready shortly. In the meantime please get ready for school, your uniform should be in the closet. But if you wish to wear something diffrent please tell us so we can inform the teachers and student body of your custom uniform." They said turning on there heel.
Ah, right school. I later found out that I was summoned here on a friday, so atleast I maneged to get myself some school supplies. Apparently I'm in class-A, (that is balams calls(idk if it is but now it will be)) Me and Iruma go to diffrent classes so it kinda suck. Butttt... I think I'm rather glad i don't have Kalego as my homeroom teacher....
Grandpa (with the help of Opera) created a cover up story, if anyone asked 'if you're Iruma-kuns brother, how come we never heard about you before?' I'm just supposed to say that 'we were living with seperate relatives but now that I'm a transfer student at Babylis, I also live with my grandpa'. A likely story i know but its the Best we got, OK?.
After getting dressed, Nagisa heard a knock on his door.
- Nagisa are you ready?" Ah Nagisa would always recognize that voice, its Iruma, and by the sound of it he's barely able to stay in place. He's most likely excited at the promise of food.' Nagisa thought fondly of his brother.
- Yeah, Yeah I'm coming hold your horses, the food won't run away." He said teasingly.
.
.
.
Opera just kept placing more, and more food on the table, as Iruma kept on shoving food in his mouth. Honestly Nagisa sometimes got whiplash after seeing the amount of food his black hole of-a brother could eat.
- Nagisa my dear grandson! Are you excited for school?" Sullivan practicaly shouted from his seat.
- Yeah.. kinda." Nagisa was hesitant, I mean he is a human and he is gonna be surrounded by demons so of course his instincts are gonna go haywire (the perfume his grandpa gave him helped him calm down only a little). (but if push come to shove, he will not hesitate to eliminate them).
Shouts of 'Iruma-chi' and 'Iruma-sama' could be heard outside the front door.
-Ah right, Iruma always walks with Clara, and Azmodeus to school.' Nagisa knew about them because Iruma told him about his 'Best friends'. Which mean Nagisa too has to walk with them to Babylis. Well here goes nothing.
.
.
.
The first meeting was... something. Clara was convinced that Iruma and Nagisa were clones. (which fair they do look alike, but still diffrent enough to not be clones). While Azmodeus stared daggers at Nagisa (most likely thinking who is that copycat next to "Master' Iruma, well his brother told him that Azmodeus can be a bit protective), Nagisa wasn't intimidated by the pink haired demon. Instead Nagisa stared right back as if he was trying to look through his soul. The said demon grew more rigid, breaking eye contact.
- Thats what I thought.' Nagisa didn't care that he might of made a terrible first impression, he would stand his ground.
- Hi Clara! Hey Azz! Its good to see you!" Iruma said smiling brightly.
- IRUMA-CHI WHY WOULDN'T YOU TELL US YOU HAD A CLONE!!" Clara screamed, offended that her friend wouldn't tell them sooner.
- Um Clara, Nagisa is not my clone-"
- Of course that copycat is not Iruma-sama!" Azmodeus added unhelpfuly, - He is nowhere near good enough to even be considered a clone!"
After that comment, Irumas smile droped.
- Nagisa isin't my clone, he is my brother. And Azz i would appreciate if you didn't make such comments about him." Iruma said in a rather unusually serious tone.
That had the two go silent. 'Brother?' .......... 'Iruma-chi/-sama has a brother!?'. Shortly after Azmodeus got on the ground showing his wing roots,
- I am terribly sorry, I disrespected your family member, I'm not worthy of serving you after such a mistake."
WOW, ok I get it you are sorry, NO NEED TO GET ON THE GROUND!". Nagisa thought was interupted again. (by Clara this time)
- OOOOOO! NO WONDER YOU ARE IRUMA-CHI'S BROTHER YOU LOOK SO ALIKE!" Clara yelled completly forgeting about personal space, she was so excited! Another friend! She now had 13 friends! SHE WAS SO HAPPY!!
- Azz-kun, its ok just don't make comments like that again, and Clara... give Nagisa some space." Iruma reprimanded fondly.
-Well... its nice to meet you all..?" Nagisa said awkwadry, ( I mean sue him, he just had a guy insult him than get on the ground and apologize, and a girl ivading his personal space in the same second.)
- Master Iruma I hate to interupt but I think you should get going to school or else you will be late." Opera poped there head through the door, As much as it was entertaining to watch the whole interaction the young Masters would be late if this continued.
- Ah! you're right!" Iruma said, grabing Nagisa's hand and pulling him along.
- Wait for us Iruma-chi!".
.
.
.
Nagisa wandered around Babylis searching for his class. He was very much lost...
- Hey, new kid right?" Nagisa turned around to look at the owner of the voice.
He saw a somewhat tall demon with white hair and... fox?.. ears? He wore a black sleevless shirt, and dark brown baggy pants. What appeard to be a bushy tail was lowly swinging behind him. Suprisingly or maybe not he wore no shoes, since it looked like he had more animalistic fetures too, and apparently had padded feet.
- Names Tsura! what about you?"
Well at least i can ask the where to find my class.'
- My name is Nagisa, By the way do you know where class @@@ is?"
- Ye thats where my class is too, come on we will walk there together!" Tsura replyed chearfully.
Huh, went better than expected'.
.
.
.
Professor Balam wad going on and on, about many magical creatures. holding each and every student in his massive vines. Where do these vines come from you ask? I dont know either.
only a handful of students weren't freaked out by Shichiro putting them in his lap and petting them ( those include Nagisa and a few others). Speaking of Nagisa it was his turn to be pet by the professor, he just sat and listend. It was kinda comfy not haveing those vines on you, but that was most likely the case because Balam knew he wouldn't try to run away.
After the class finished, Tsura approached him again.
- Damn dude, you must be fearless, or just plain stupid to just stay put in Professor Balams lap, when the vines let you go!" He laughed, the new kid sure is interesting!'.
Nagisa just stared. -was that supposed to be a backhanded compliment??"
-Anyway, you also in class-A?". Nagisa nods. - Hah, me too! I tell you what, you're new here i advize you to stick close to me."
-Alright..? Where to now?".
-Just follow me!" Tsura flashed him a smirk.
.
.
.
It was finally lunch time. Suprisingly or not, Babylis was just like anyother school in the human world. Nagisa spent the whole day with Tsura, the demon was pretty smart from what he seen, so maybe keeping close to him wouldn't hurt, it would mean getting help with the subjects. And possibly other uses.
Out of the corner of his eye, Nagisa spoted Iruma, and other demons gathered around him. Seems like his brother was once again trying to eat the cafeteria out of food.
This day wasn't as bad as he thought!
- Hellooooo, netherworld to Nagisa, do you copy?" He just now realised that he spaced out, because Tsura was now waveing his hand in front of him.
- Oh, yea I just spaced out for a little."
Tsura turned in the direction Nagisa was looking.
- Ah! Iruma cought your eye huh? Well he is Lord Sullivan's grandson after all."
- Well, a brother sometimes can't help but worry. Especially if your sibling is a trobule magnet." Nagisa sighed fondly, he may not have knows Iruma for long, but they already had a strong bond.
...'
Why is it so quite all of a sudden?'
Tsura just stared at him, as did some other demons around him.
- Ummm... why are you staring at me like that?" Nagisa was getting uncomfortable, did i say something wrong or what?'
- You are surely lying.." Tsura said in a shaky voice.
- Lying about what?"
- Are you sure HE -" he pointed at Iruma (who was now looking over to see whats going on). - The Chairdemons grandson is your Brother."
As if on que, Iruma smiled and waved his way. As chearfull as ever, huh.'
That prompted Tsura to screech
- The Chairdemon has TWO grandson's?!"
Which in turn caused all demons turn to look at Nagisa.
Well me and Iruma never even thought to keep this a secret, but this is not how I thought it would go.'
From what Nagisa could see, all of the misfit class (except Clara, and Azmodeus) were now staring at him in disbelief.
- Am.. am I hearing things right?" a boy with neon yellow hair asked the boy with a what looked like a white bag on his head.
- Oh my! I didn't know Iruma had a brother!" said a tall girl with long blond hair, and an outfit that screamed DRESSCODE VIOLATION.
- Hehe it's Nagisa-kun!" Clara was waving her hands in the air, calling Nagisa to come over and join them at the table.
Nagisa didn't see a problem in joining his brother and his friends at the table. Afterall its better to get to know Irumas classmates, so if one of them tried anything... He would take care of them. As he made his way over he spoted a lavender haired demon staring at him, but he didn't feel anything threatning from the guy so he just ignored him and sat down.
.
.
.
Iruma had a brother.... IRUMA HAD A BROTHER.' If you told Purson about this he would think youre crazy and disappear, but now that hes seeing it with his own eyes.... It was such a shock in fact, that he completly dropped his ability. Luckily the other demons were only paying attention to the revelation that was Iruma having a brother'.
Thanks to his bloodline magic he was able to overhear others talking about a transfer student, but he would of never thought it would be his unofficial class leader's sibling.
he was curios about how diffrent the two of them are, after all they did look similar but had some noticeable differences, or maybe they are more similar than we think?
.
.
.
Meanwhile in some distant border control base.
- Mann.. this was almost too easy, heh... and I thought demon were 'stronger' than humans. And yet here you are." A red haired boy said coldly, blood dripping down his fists, the gun still emitting smoke after use. That grisly smile on his face, his golden eyes almost shining in the dimly lit room after the human shot at the lamps, It was terrifying.
He began to stalk closer.
- No.! NO! NO! NO! Please! Stay Back!!" A panicked demon screamed, back pressed against the wall, the knife the kid has threw was still stuck in his shoulder. His wings were gone the child ripped them clean off, His mana was running low. He was... Defenceless.
- You really are annoying when you scream so loud, jeez. Its kinda getting on my nerves now.." Karma didn't stop, he wouldn't, he just found a way to the demon world, and he was gonna cause as much chaos as he can, even if it mean losing his life.
Karma raised the barrel of his gun to the demons head.
- Well, it was fun toying with you all, but I still need to finish you off, So! any last words?" he asked chearfully with a sadistic smile.
The demon, knowing nothing would save him now just accepted his fate. He was just sorry he would never return home to his wife.
BANG.
-Alright! Where to next." Karma picked a random direction and headed out. He would soon need to clean the blood off though, it really started to stink.
.
.
.
Henri recived a report about a raid on a border control base, he was mad, all his men were killed in cold blood, and he will find the one responcible. And bring them to justice. The situation with Sullivan once again going to the human world will be now on a back burner, first he has a murder to find.

Chapter Text
Nagisa didn't know why he agreed to this! 'Its gonna be an amazing trip with grandpa, to the nearby forest!' he said. 'Its gonna be so much fun! And you can bond with eachother while on it!' he said.
Well to bad, because he and Iruma were lost (God fucking damn it)
- Hey, Nagisa do you know where we're going?" Asked his brother.
- I got no clue, but I think we are going north." Nagisa was on guard, if they encounter any danger he was ready to strike.
Urgent meeting my ass! Why did grandpa think it was a good idea to leave me and Iruma in the camp, and then all but fucking dissapear!'
.
.
.
Karma was just wandering... totally not just causing any chaos! Of course not!
Never mind the fact the blood stains on his shirt were still visible.
He was here for a while now.. kinda boring if you ask him. All there was to see were some purple trees with orange leaves and blue spiky fruit (was it even edible??)
He maneged to snag some food from the demons in that base, but still he would need some other source of sustinance!
- Man, this place is desolate. Not even a single soul around. Is hell really this empty, or did something happen?" He was talking to himself, but it wasn't long until he felt eyes on him.
Something or someone was stalking him. Little did that person know that Karma was like a hungry predator, and he, an unfortunate prey.
.
.
.
Iruma cought a smell of a deceased Corpse, all he could smell was the slowly rotting meat. (Just how long has this thing been here?'). He thought the animals here would devour their prey whole, and not leave anything behind.
Nagisa seemed to smell it too, by his reaction. The smell was horrible!
Nagisa began to walk closer slowly, and was it just Iruma's imagination or did Nagisa really not make a sound when he walked? He concluded that it wasn't important right now, and he could ask later.
Iruma followed Nagisa as silently as he could and peeked out from behind his shoulder. It was morbid; the poor victim was unidentifiable. It was brutal; Iruma felt sick just looking at it.
- Who would do such a thing?" His voice was barely above a whisper.
-We can't stay here. Come on, we have to go. It's too dangerous here." Nagisa pulled him hard. He was right. They needed to leave, or else they might run into whatever did that to the poor demon.
The bushes were rustling not too far away, which startled the blue-haired duo.
...
Out stepped a red-haired man with golden eyes, somebody Nagisa thought he would never see here (kinda ironic since it's hell, but still). He didn't know whether to be happy to see a familiar face or be scared because only God knows what goes through Karma's mind.
- Karma? How the hell did you get here!" Nagisa still wasn't sure he honestly wanted an answer. With Karma, everything was possible, which was quite scary.
- Nagisa long time no see!" Karma knew that when he didn’t see Nagisa in class for a few days, there was something wrong. However, he would never have thought that Nagisa was in hell, which was kind of ironic since they were both assassins.
He flashed the blue-haired boy a toothy smile; he was going to have a blast annoying Nagisa.
- huh, you know him Nagisa?" Another blue haired boy asked, how the hell did I not notice this kid before?'
- Ah, yeah, Karma and I went to the same class!" Nagisa replied, smiling. He knew his brother would have a hard time getting to know Karma, but he hoped it might not end in disaster.
- Oh, I see! My name is Iruma, and I'm Nagisa's brother, nice to meet you!" Iruma, ever the polite one, stuck out his hand to Karma to shake it.
Karma just continued to stare.
- Hey, Nagisa, how come you never said you had a brother? And does being a femboy run in the family or something~?" he asked with a cheeky grin. Oh, he was going to have a field day with this!
Nagisa splutterd, and Iruma stood frozen in place from shock
- HEY JUST WHAT ARE YOU ON ABOUT!?" Nagisa knew this would happen, he dreaded the unrelenting teasing that was to come.
- Aww, don't worry about it. You don't have to deny it! After all, everybody knows!"
- WHAT DO YOU MEAN 'EVERYBODY KNOWS'!"
Iruma felt like he was intruding on something private. He was debating whether to leave and give them some space, or just keep standing there.
- Ah, right! How did you get here, Karma? Did somebody sell your soul too?" Now Iruma was curious.
-Sell my soul?" Karma looked at him incredulously. - Do you really think I would allow anybody to sell my soul?"
- Than how did you get here?" Nagisa was getting inpatient 'Its a simple question! Just answer it already God Damn it!'
-Oh! I saw a cult perform a ritual that in turn opened some sort of portal that I went through!"
What really happened was that Karma, who was searching for Nagisa ( He didn't do it because he was worried fuck you) So, he started searching abandoned buildings when he stumbled upon a ritual. He decided to hide behind a pillar and observe. He saw what he thought to be a demon in a suit say, "You humans should stay out of the netherworld, but since you've already seen me and the portal, we will have to erase your memory of this and burn the book you used for the ritual." Karma quickly hid before he saw a bright flash. When he peeked out, the portal was still there, but the cultist and demon were gone. So, out of curiosity ( No, he was not, in fact, desperate to find Nagisa fuck off ) He jumped in and arrived at the border control base, where he ended up 'subduing' all the personnel before escaping and causing chaos wherever he went.
Nagisa called bullshit there was no way that was the whole story, i mean he had blood stains on his clothes!
But he decided he didn't want to deal with this now.
.
.
.
Sullivan found them 33 minutes later. He had sobbed and cried and apologized to his grandsons while hugging them within an inch of their life.
- OH, MY SWEET GRANDSONS! I'M SO SORRY I LEFT YOU! YOU MUST HAVE BEEN SO SCARED IN SUCH AN UNFAMILIAR PLACE!!" Sullivan cried out.
Karma just wached from the side. Well Nagisa looks happy'
-Oh, and who might you be?" Sullivan turned in his direction. - Are you perhaps injured?"
- If anything, he's the one who injured someone," muttered Nagisa.
Karma just smiled.
- Nahhh I'm fine, I just stained my clothes."
- Well we should still take you to a doctor so you can get a check up"
-No! He's a human, too. He can't go there!" Nagisa said through gritted teeth.
-Ah, is that so.."
.
.
.
Opera opened the door to the sight of his three masters and a red-haired teenager.
-Lord Sullivan, did you perhaps adopt another grandson?" they said, their ears pressed closely to their head.
-Oh no, I wasn't adopted by him by any means." Karma kind of felt sorry for the cat; just how many times has this happened for them to have this reaction?
You see, Opera, this human child." 'I'm not a child, old m-!' was heard from Karma before Nagisa silenced him with his hand over his mouth. "And it would not end well if a demon doctor found out about his origin! So I thought, why not give him a checkup? After all, he is Nagisa's close friend!"
...
- I'll see what I can do," they said, turning around. - Please follow me."
.
.
.
3:13 pm.
The five of them were sitting on couches, discussing the newly arisen problems.
- So I too will study at Babylis alongside Nagisa and Iruma?" Karma was not expecting the two demons to be so welcoming, especially since he's a stranger.
- Yes! You see, Nagisa was really happy to see a familiar face here in the Netherworld, and I'm glad there is someone aside from his family whom he can trust.
Karma went red in the face. ( No, he was not blushing; he was just embarrassed about the confession shut the fuck up! )
- So from now on, you'll be staying here in my mansion since you can't go back to the human world! And because Nagisa insisted on you staying~" Sullivan added with a little wiggle of his eyebrows in Karma's direction. (he may be old but he can see that the two of 'em care about eachother.)
Hehe! Looks like I'm going to have a grandson-in-law soon enough!
Karma's face matched the color of his hair at that comment and gesture.(No, that wasn't a blush, it's pure embarrassment screw off )
- Hey, Karma, come here for a sec. I need to show you something!" Nagisa yelled from upstairs, silencing any further comments from his guardians.
- Yeah, I'll be there in a moment. Well, I guess I'll take my leave now."
.
.
.
Ali was TERRIFIED that the teen was not normal; a terrifying aura accompanied the redhead. He made Ali feel really uneasy.
- Huh, so this thing just lives inside your ring full time?" The kid asked
- WHO ARE YOU CALLING A THING?! I HAVE A NAME YOU KNOW?!" Ali screeched at the top of his lungs.
- Calm down, there's no need to get mad all of a sudden." He finished with a wide-eyed smile.(It was fucking terrifying!)
Alright, alright, give it a rest, you two. It's getting late, and Karma, weren't you supposed to go to Opera to finish the arrangements?" Nagisa stepped in as the mediator so Karma wouldn't do anything stupid.
- Heh, you could just say you want me to go, Nagisa~" he said with a devilish smirk.
Karma got up but stopped in the doorway.
- It was nice seeing you again Nagisa~" he added in a teasing tone of voice, and left.
Nagisa was speechless, and Iruma yet again felt like he was intruding on something private.
Nagisa excused himself and went to his room. He just laid there staring at the ceiling, he was kind of glad to see a familiar face, but knew just how much chaos Karma would cause.
With that thought in mind Nagisa slipped into a deep dreamless sleep.
Chapter 7: THESE HUMANS ARE GONNA DRIVE ME INSANE! -Kalego.
Summary:
Karma and Nagisa go to class together, Karma makes a frienemy, Kalego is slowly going insane at the thought of another member of the Sullivan household. ✌️
Notes:
(See the end of the chapter for notes.)
Chapter Text
He woke up in a cold sweat. He sat up and looked out the window to see a black hell-cat scratching at the window. Turning to his left, he saw the clock display the time as 3:13 a.m. 'This is ominous, but it's not like I can fall asleep again,' he thought. He had a bad feeling about today.
He got out of bed, grabbed a change of clothes, and stepped into the shower. The ice-cold water barely helped him wake up. He grabbed the food he had prepared the night before and took off for Babylis.
.
.
.
Kalego was currently sorting papers and organizing material he would have to teach the misfits. He saw many students land before the gates, and the student council led by Ameri Azazel greeted everybody.
After most students went their separate ways, he saw them.
Kalegos's worst nightmare (second only to Opera.)
The problem children
Kalego was dreading what was yet to come, but then he noticed there were two more demons with them. One with light blue hair was walking and talking to Iruma, and a red-haired brat that looked too similar to Opera for his liking.
He shook himself off, got his act together, and went to The Royal One.
Narrator: Kalego had no idea who Nagisa or Karma were since he was sick when they first enrolled in Babyls.
.
.
.
The lesson was going well. The problem children were quite tame today, which was a miracle in itself, but what bothered him was that it was too quiet. Most misfits were staring into space, not paying attention. Usually, there would be one brave demon trying to speak to another, but they would stop after Kalego threatened to double the homework.
Now, it's like their souls left their bodies, leaving nothing but empty husks.
The only ones that weren't affected were the trio. Iruma seemed normal, Valac was... the usual, and Asmodeus was only paying attention to Iruma.
Kalego decided that whatever it was, it was not worth asking about, instead opting to continue teaching.
.
.
.
Karma sat next to Nagisa. He could see a somewhat tall demon with long white hair and fox ears. The demon had a toothy grin on his face as he sat down next to Nagisa on the other side.
- Yo! Good to see ya again, kid."
- Oh, hey, Tsura, how are you?" Nagisa got used to the fox demon over the next few days and steadily became good friends with him. (And boy, was that a hard topic to explain to the demon.)
Karma just stared. Nagisa was taking this in a stride. Yeah, he'd been here longer than Karma and all, but they still needed to remember that those were demons, and neither of them knew what they might do to them when they least expected it.
- Hmmm? Who's that?" The fox demon, Tsura, asked, turning to him.
- The name's Karma," he said with a small upturn of his lips.
- What kind of parents name their kid 'Karma'?"
- Oh, please, what is there not to love about the name Karma?" He tilted his head down, a dangerous glint in his eyes, making the demons around him uncomfortable. Some even scooted further away.
Well, except Tsura, since he flashed him another toothy grin.
Looks like it won't be easy to intimidate him.
- Heh, I like your guts, kid!"
- Not a kid, you walking fur coat~".
- Hahaha! I can already tell we'll get along great, Karma." Tsura reached out his hand to Karma to shake it. Not even a second after Karma shook his hand, the demon ripped his hand out of his grip with a poorly disguised snarl. Looking down at his hand, he saw blood.
Looking up, he saw Karma smirking at him, holding up his hand, showing many tiny blades on his hand.
- Fufufu~ You should really be more vigilant, you know? I'd say expect the unexpected~" His smile and eyes widened, it made for a truly scary sight.
- Karma you dumbass! SMACK "What do you think you're doing?" Nagisa was exasperated. This was just like when Karma arrived in class E and tried to kill Koro-Sensei! at least he didn't try to stab Tsura.
- Haha! Not bad, red-head, not bad!" The grin was now back on the demon's face.
Karma's smile promised chaos and mischief.
Nagisa knew that smile all too well. He put his head in his hands, regretting his life choices.
.
.
.
The bell screeched, signaling the start of the lunch period.
Students flocked to the cafeteria, pushing and shoving each other just to get there first. When Kalego and Balam entered, most of the students were already seated at the tables. They sat next to the other teachers.
- Have you heard? Apparently, Iruma has a brother! I was on a trip with my class, so I wasn't there. Can any of you fill me in?" Robin asked his seniors, excited about the news.
Kalego did a spit take.
Balam, already having met the young human, decided to recount his meeting with Nagisa, omitting the more private parts. (like the human part, and falling asleep on him alongside Iruma).
Kalego, on the other hand, finally realized why he felt so much dread this morning, or why the misfits were behaving the way they were. 'There is another spawn of Sullivan in Babyls?! Oh sweet Delkira save him, he can't deal with another problem child'.
.
.
.
On the other side of the cafeteria, three humans and a class of demons were talking. Iruma noticed his teachers' reactions, and he got curious.
- "What do you think they're talking about? I saw Kalego spit out his drink."
- "Maybe somebody died." Karma said, smiling.
- "Why are you like this? You were pretty tame yesterday. What happened now?" Nagisa could feel a headache coming on.
- Hehe~"
Why did he want Karma to stay in the netherworld with him again? And was there still a chance to send him back?
Notes:
ITS FINALLY DONE!
My creativity is dead and whining, and I'm so tired and happy that I could cry. :,)
This is the end of this fanfic, but not this series.
I plan on making more works in this style, but as one-shots because it's too hard to write so much.
