So little Author note at the beginning. Yes, it's my first story and yes English is NOT my mother language, so please excuse errors in typing and spelling I'm doing the best of my abilities to present you a readable story. I try to write when I can, but I am working full time and a very VERY lazy person so don't expect too much of me (pls don't). without further ado let's start the Madness that is born out of my mind. I only watched the anime and didn´t read the manga so sorry if something isn´t right for you.

Chapter 01

Underworld - Capital of Lucifaad - Sitri Hospital

In the new Capital of the Underworld Lucifaad, stands one of the most known Hospitals of the Underworld which is owned by the House of Sitri from the 72 Pillars. In that Hospital Doctors and Nurses were running around and moving Patients around and preparing all sorts of rooms. One room especially was being tended to tonight because of the oncoming Birth from the well-known house of Gremory that is from the 72 Pillars too. Its known for bringing the current Lucifer, Sirzechs Lucifer formerly known as Sirzechs Gremory, who couldn´t wait more for his new baby Sister or Brother.

POV Change Friends and Family

"SIRZECHS! calm down just because you can't wait any longer doesn't mean that the child will come any sooner." Said a silver haired maid to a male with long red hair who was bouncing around the room. "You are the Maou Lucifer of the underworld and soon the be older brother, so just calm down and act like one." She scolded him harshly making him pout like a little kid.

"But Grayfia I just can´t wait any longer, I want to hold him or her and just smother him or her for all eternity." Exclaimed the excited long red headed male whose name was apparently Sirzechs. He appeared to be in his early 20´s with blue-green eyes and an attire that could be described as a formal looking robe with heavy armor plates sitting upon his shoulders.

"YEP! YEP! I understand exactly how you feel Zech's-Chan, it´s just the same with my cute and little Sona. That's what older siblings are for." Said a jumping girl with black twin tails and an outfit that can only be described as a uniform of a magical girl that was hugging her figure nicely.

"Just what Grayfia said Sirzechs calm down, wait and everything is going to be fine after all the birth of a child is an exhaustive activity for the mother and the child, besides Lord Sitri is known as one of the best doctors of the whole underworld and a long-time friend of your parents. I'm sure he can handle everything perfectly." Exclaimed a male with shoulder length green hair that like Sirzechs was dressed in a ceremonial robe with armor on his shoulders. That was Ajuka Beelzebub, a fellow Maou with the Title of Beelzebub and a childhood friend of Sirzechs.

"Thank you Ajuka I think I'm just overreacting a bit." Said the sheepish looking red head who was still squirming like a little kid.

"just a bit Sirzechs?" Stressed out the maid, Grayfia, much to the amusement of the other occupants in the room.

"Go a bit easy on him Grayfia, it´s a big day for him. Well I remember that Serafall was way more excited." Said Ajuka while looking at the magical girl. "By the way Serafall, what are you wearing?"

"Ouh that´s the outfit for my new TV show that's going to start soon. It´s really comfy and I look super cute in it don´t you think." Remarked the overhyped girl with a wink.

"I think we´re all a little excited, but it's all over now." Announced a new voice as a man entered the room that looked surprisingly similar to Sirzechs.

"Father please tell me how is mother and my dear baby sibling, are they well?"

"Yes, yes everything was perfect with only some minor complications, but everything is ok now, besides the Sitri's helped us they are after all the best doctors in the underworld. But enough talk for now come in everyone I think you will be surprised." Said Sirzechs father with a reassuring smile.

After everyone followed Zeoticus Gremory through the floor into a room, they saw a beautiful brown-haired woman holding two bundles of clothes, at a closer look you could say that they we´re babies.

"Ah Sirzechs, Grayfia, and dear Maou´s I'm glad to say that I gave birth to two beautiful children. The little sunshine with the red hair is named Rias and the boy is Kain, aren´t they both just adorable?"

"Mother ... You´ve got twins, but the doctors said that only one child was coming." Sirzechs was at a loss of words, in devil society it´s rare to get pregnant but to get twins is even more rare.

"We know Sirzechs but at the time Rias came Dr. Sitri noticed that something wasn´t right so he checked all the vitals with a little spell that the doctors use here and discovered that there was a second child hiding behind Rias´s magic signature, we don´t know how Kain managed to do that but somehow but he hid his own magic signature, and if he can do that as an infant we will not know what deeds he will do in the future." Said Zeoticus while looking at the young boy.

"It´s unheard of infants controlling magic but to deceive trained nurses and doctors. We need to watch his growth closely or he will drop surprises that will let that one here look small. I would say that I have some matters to look into so please excuse myself, and before I forget it, congratulations Lady and Lord Gremory and you too Sirzechs." Said Ajuka before he teleported himself to Satan knows where via magic circle and left the happy family and fellow Maou's.

"Well that's Ajuka always thinking of work and his research. But the baby´s are sooooo super cute almost as cute as Sona-Chan, I bet they all will become great friends in the future. But from me as well congrats on such wonderful children and becoming an older brother Zech's-Chan maybe now we can share cute baby pictures to embarrass our cute siblings in the future. I will leave you all alone now to catch up and do your stuff that you all want to do." Said Serafall before also leaving via magic circle, the only difference is, that it was shooting pink sparkles everywhere.

"So now that everyone left why don´t we take a closer look, they should be sleeping right now." Zeoticus said as everyone scooted closer towards the mother and the resting twins. As Sirzechs and Grayfia approached the twins they could see that Rias had the typical red hair of the Gremory's and normal magic reserves for a high-class demon, but what shocked them was that Kain had next to no traceable magic and had his mother's brown hair. In the next moment he opened his eyes and smiled, they would expect a baby to scream at every chance but no, he just lay there and smiled and his eyes, these magnificent and mysterious lilac eyes that looked exactly like the eyes of his mother.

Time Skip - 8 years later POV change Kain

"KAIN! WAKE UP, IT´S MORNING." Was the first thing I heard as I began to wake up.

"Uggh Rias do you have to be so loud in the morning?" I said as with my still closed eyes, trying to go back to sleep, just the be tackled by a familiar weight on my chest region.

"Of course, it´s our Birthday after all so we have to wake up early to dress ourselves and look presentable." Answered my older twin sister, even if she acts like a six-year-old sometimes.

"But mom and dad already have everything planned out and invented every High-Class Pillar House. Besides Sona is the only one that's going to be early and she already knows you in your ´messy state´. Besides, get off you're heavy."

"What´s that supposed to mean my dear Otouto?" Asked a completely unsuspecting sister of mine.

"Nothing. By the way how in all 7 circles of hell did you get in here?, I've locked all windows and doors AND sealed off my room with magic so that nobody could enter my room." I said as I looked around the room noticing that the windows were closed and the door wasn´t kicked down either." Oh, that's easy. I hid in your closet and waited till you we´re asleep so I could join you in bed and cuddle with you." Rias said, like it´s completely normal to hide in somebody´s closet and sneak in said person´s bed to sleep with him. Nude.

"Just get outta here I want to shower and dress myself."

" I could wash your back." Rias told me with a smile.

With nothing more said from my side I threw her off myself, opened the door and kicked her out and locked the door behind her.

BANG

"LET ME IN KAIN! I just wanted to join you in the shower and show you the love and affection of an older sister."

"NO shower in your own room or I will call Grayfia." Satan himself damn it, now I know how Sona feels with Serafall as her sister, maybe we could start a club. Depressed younger siblings seems to be an appropriate name.

I made sure to even lock the bathroom door that is connected to my room in case Rias would find a way to get over my door, and the magic wards, and my mahogany table that I pushed in front of the door which is made of the Mahogany trees that can only be found in the familiar forest where the trees are 300 feet tall and breath fire. I love that table. After I stepped into the shower and turned on the water I began to relax.

"Already the ninth birthday of me and Rias huh, I wonder how many people father invited probably half of the Pillar families and other people." I thought as I stepped out of the shower and began to dry myself off as I heard knocking on my door.

"Lord Kain are you inside the bath?" Asked a familiar voice.

"Yes, Grayfia I already was woken up thanks to Rias and just finished my shower, please wait a minute and I come out." I quickly dressed myself in simple looking white shorts and a black shirt as I stepped out.

"Ok I'm finished and ready for breakfast." I announced as my stomach growled making my cheeks turn slightly red from embarrassment."Sorry."

"Of course, Lord Kain please follow me to the dining room the rest of the family already awaits you." She said as we walked towards the dining room.

"Grayfia stop calling me lord every time, I told you to just call me Kain. Not Sama, not Lord and above everything NOT Master. We´re family Grayfia so please just call me Kain."

"Fine I will call you like that. When we´re alone." Grayfia said with a small smile that I almost didn´t see.

"Thank you. Besides Grayfia, you look much better when you´re smiling, you should do that more." While we we´re talking I didn´t notice that we already reached the dining room and that everybody was seated and looking at us. Father and Mother were smiling while Rias looked ready to leap over the table to hug me, the only thing stopping her was Sirzechs who was hugging Rias much to her discontent and my amusement.

"Onii-Sama let me go I wanna hug Kain and not you!" Yelled the red bundle of energy at Sirzechs, which he only laughed off. "Rias I have a better idea. We both will hug Kain, after all he´s your little brother and mine too so we must share him." Sirzechs said and I started to turn pale.

As they began to approach me I looked behind me to hide behind Grayfia, only to realize that she moved the wall on the far left to chatter with the other servants of the mansion. With no other choice I made a bee line towards my mother.

"Mother please help me they lost their mind again." I cried to my mother as I evaded the tackles of my older siblings and found myself in the arms of my mother who was ... hugging me too? "No please not you too mom."

"Ouu whats wrong with some motherly love in the morning. I like to hold my children, after all that's the right of the mother and nobody others." oh oh mom is turning yandere again and father was slowly backing up too to the safety of his newspaper. Traitor.

"Why am I cursed with such a family. Why Satan is this happening only to me." I silently cried to every existing deity that could help me, but I received no answer.

((Sitri Mansion, same time))

"SO-TAN PLEASE LET ONEE-SAMA HUG YOU AND DEVOUR OUR YURI YURI SIBLING LOVE."

"GO AWAY YOU SPAWN OF HELL! I CAN'T STAND YOU ANYMORE !"

For everyone living inside the Sitri mansion it was a normal morning. Lord and Lady Sitri sitting on the dining table and drinking coffee while the young heiress Sona Sitri was running around trying to hide from our beloved Magical Girl Serafall Leviathan.

((Back to Kain))

After Breakfast I managed to escape my family´s clutches and decided to wander in the gardens where nobody would find me, hopefully.

"I wonder if Sona is coming over early. I really would like to play chess right now." I mused aloud not suspecting a thing.

"Hoh hoh desperate much Kain, I didn´t know that you could make such a long face." Said a voice behind me with a hint of amusement.

"And I didn´t know that you could tease people, after all you always act so strict around everyone." I said without even turning around as I already knew who the owner of the voice was.

"So, what was that chess match against me that I heard about. The day just started, and you already want to lose?" Exclaimed Sona as she came into my view as she sat down next to me

"Not hanging out with Rias like every time you come here?"

"No, she´s searching all over of the mansion and turning around every stone in her path to find you, besides I had enough insanity for my morning." Sona said with a slight shiver. Not wanting to know what she had endured I decided to set up the chess board with me taking black.

"Ah so you too huh. I wonder if all siblings of a Maou have THAT kind of problems with their older siblings." I replied quickly thinking of two individuals with red hair that lived at this mansion. "I´ll certainly hope not but if they do, they have my condolences." Sona answered with a hint of sensitiveness.

"We´ll enough said don´t we have a match?"

After they began their match in the shade of the tree that they we´re seated at, they didn´t notice that they we´re being watched by none other by Sirzechs and Venelana Gremory while Rias was still running through the halls trying to find Kain much to the amusement of the maid´s and butler´s that were watching the young girl.

"Sirzechs I take it you´ve got the results of Kain´s last test from Ajuka?" Asked a serious Venelana with an expression some people can´t even imagine on her face.

"Yes, mother I have but ... Nothing changed. He still isn´t showing any sign of any normal or demonic energy within his body to the extent that he can´t even manifest his wings and he doesn't have any affliction with our Power of Destruction. The only positive aspect is that he continues to grow extraordinary intelligent that he even could rival Ajuka in a few years." Said a sad looking Sirzechs while watching at his younger brother from afar knowing how hard he has it to find friends because of this blasted curse as he calls it.

SIGH "Why has Kain to suffer so much from his lack of power. He even lost his right as the heir of the family to Rias, and the Council of Elders and the Pillar families won´t acknowledged him. Have you heard what he gets calls behind closed doors? Commoner of the Pillars, weakest Devil, some even dare to call him the disgrace of Gremory's. Sirzechs I fear for him that it will get even worse." Venelana said with tears in her eyes. The sight alone caused Sirzechs to become sad and angry at the same time. Sad because he knows how his mother feels and angry at the people who dared to insult his precious little brother. He could only pray that Rias doesn't find out about this. She might even react worse than him and might do something stupid. But the biggest mystery is Kain himself, he knows that he has zero talent in magic, so he trains his body in response and ignores all forms of insults that are thrown onto him and just keeps trying to get stronger and stronger.

"When the time comes he will need every type of support that we can give him. I swear to you as the Maou Lucifer that I will protect him from everything that will come after him." Sirzechs stated with as much passion as he could muster to his mother to rise her spirit again.

"Yes. I think you´re right. WE will help him in the future and for now we´re going to be the best family ever, but that also means that I as a mother have to embarrass him in front of his little girlfriend." Venelana said with re won vigor as she strode towards her youngest son. Sirzechs could only sweatdrop at her sudden change in emotion and decided to go back to his office and make his much-hated paperwork before Grayfia decided to get him again.

"Hello, you two Lovebirds how are you doing?" Asked Venelana with a mischievous smile while Sona and Kain we´re blushing from ear to ear.

"Mom! we're not Lovebirds! we are just friends." replied Kain with a face as red as his sister's hair.

"m-miss Gre-Gremory what nonsense are you talking about." Said Sona with an equally red face.

"Yare Yare can´t a Lady such as I have a little fun with her son and his girlfriend. Oh, Sona imagine what Serafall will say when she hears about this." with that said Sona´s face lost its color near instantly. "Please anything but that. What can I do to stop you from saying that to my sister.?" She begged in desperation to Venelana which made her smile even more.

"Oh, nothing much just be Kain's escort for today´s party and I keep my lips sealed, by the way you both should get dressed the party starts in a few hours and I think you both have to prepare a bit." She stated with a wink and left.

"I'm sorry Sona that my mother coaxed you into one of her schemes again and made you come with the party to me." Kain apologized.

"No, It´s okay. I don´t mind if it´s you." Sona muttered quietly. "What did you say?, Oh and it´s Checkmate for you." Announced Kain as he looked at her with a stoic expression.

Sona looked at the board and couldn't believe it. Kain´s king was standing directly in front of her king being flanked by his last 2 pawns and his queen standing behind Sona´s own king.

"Your tactic is abnormal. Who would use his own king to attack other pieces?" Asked a confused Sona.

"Sona. A king has much more uses than sitting behind his troops and watching a battle. A true king leads his men onto the battlefield and shows them that he stands with them and not behind them or do you except any sane soldier would sacrifice his life for a coward that hides." Kain said albeit glancing around nervously. "I think I hear something coming our way Sona..."

"Now that you mention I think its screaming your name."

Before even one of the two could react Kain and Sona were tackled to the ground.

"SO-TAN, KAI-TAN finally found you tehehehe." Exclaimed a happy Serafall while hugging them to death.

"Serafall Sama what are you doing here don´t you have work to do." Kain said while trying to catch air in a desperate manner.

"Nope! Already finished everything and didn´t I tell you to call me Sera-Tan. I was searching So-Tan when I found you both spending lovely dovely time together." Serafall laughed while hugging them even tighter.

"ONEE SAMA get off me. We have to get back home and get ready for the party. We see later Kain." With that said Sona and Serafall left myself alone in the garden.

"Well. Better get ready before Rias or Sirzechs find me and drag me off somewhere else and decide to play dress up."

(Time Skip right before the party)

"Lord Kain Gremory and Lady Sona Sitri has arrived!" Exclaimed a servant loudly making everyone turn towards us.

"Well here we are surrounded with a facade of false smiles and greedy looks trying to gain some kind of favor within my family." I whispered into Sona´s ear. "They are devils after all. Greed is a major sin amongst them." Sona quietly said back not even looking at me.

As we made our steps down the stairs we noticed that many people were staring at us, mostly at me. I didn´t care as I tried to see any familiar faces. I saw the Maou's sitting at a big table at the end of the hall, quietly talking to each other and I saw my parents discussing something with the Phenex family. The Phenex's were, as many other people inside this hall, a family of the remaining clan pillars. I didn´t exactly hate them, only the youngest son Riser Phenex was an arrogant asshole but that's it.

As I kept looking through I noticed Rias was standing at the buffet with a man who looked a little bit older than her and myself and he had shoulder length black hair and wore some kind of black suit with golden trimmings and a grey vest. Tugging at Sona's hand we managed to make our way through the crowd of guests we arrived next to them.

"Well if it isn't my dear cousin Sairaorg, didn´t knew you would be coming over." I greeted them, making both turn to us.

"Ah Kain, you sure took your time to finally come here. What were you doing, having fun with your girlfriend?" Sairaorg joked making Sona blush and Rias looking at her with jealousy.

"No, I just don´t like party´s. You of all people should know that, considering how much you hate them yourself." I said looking at him with a knowing smile.

"Well what can I say. Family stays family, you just can´t ignore them." Sairaorg said with sarcasm. "By the way how is training going?"

As Sairaorg and I began to drift off in our conversation, quickly forgetting everything around us, Sona and Rias just shared a look and sighed.

"Why do these two always think the world is about training and nothing else."

"You said something?" Sairaorg and I said at the same time, turning towards the girls making them sigh once more.

As we all began talking about random stuff one question from Rias made us silent. "What do you guys dream about?"

"I want to become a Maou." Sairaorg answered with as much determination as he could muster making me giggle a bit. "Called it."

"I want to open a school for rating games where every devil can attend regardless of high class or low class." Sona said with a straight face making us look at her. "Ay truly a great dream young Sitri. You have my support." Sairaorg added while laughing.

" Yeah mine too." I muttered.

"I will marry Kain." Well that's Rias for you Bro Con even in serious situations. "And you Kain what is you dream." She asked with a smile probably hoping it´s about her.

"It´s simple really. I will become the strongest being across the Dimensions." I stated making them look at me with surprise.

"And you call THAT simple?" Asked a confused Sona.

"As I expected it from you haha. Always reaching for the impossible Kain." Said Sairaorg towards me as I raised my eyebrow. "Who said it´s impossible? If you truly desire it, with all your heart, and with lots of hard work you can achieve everything." I told them making them silent once again.

(WITH THE MAOU`S)

"Well Sirzechs your little brother truly surprises me again and again." Said a smiling Ajuka. "I do wonder it its running in the family."

"Well you only need to look at me and you have your answer." Sirzechs joked.

"Do you think he´s serious with what he said?" asked Serafall.

"He did sound serious Serafall. Or he didn´t and tried to empress Sona and make her go out with him. Who knows." Ajuka smirked knowing how The Sis and Bro Cons will react.

"NO WAY HE´S NOT STEALING SO-TAN FROM ME." And with that Serafall was off running towards her sister.

"I'm glad you only were joking Ajuka because Kain would surely take Rias out on a date." Sirzechs said with a from face, still believing that his little siblings have a thing for each other. "Why is the only normal one the youngest of the three siblings." Ajuka thought with a shake off his head.

((AFTER THE PARTY) KAIN`S POV)

"The Party was ok till Serafall rushed at me and demanding that I give her back her sister." I thought to myself while walking through the halls of the mansion. "At least everybody had fun and the food was great."

As I entered my room I instantly noticed something was different. It felt wrong. "Didn´t I close the window?" I muttered quietly as I moved towards the window and closed it.

"Found you." A voice said behind me and before I could turn around I lost my consciousness.

Well the first chapter is finished, and I hope you all liked it. If I made any grave mistakes, feel free to say them to me and help me to get better.

If you didn't like it, tell me what you didn't like or tell me what I could better but please consider. Everybody starts small. If you have any suggestions write them in the chat and I consider if I add them to the story. I don't know when the next chapter comes but I try to write it as fast as I can.
