So this is my first fanfic SO... LET THE SIN BEGIN;)

Family… a word that's supposed to mean trust, love, and compassion, well that isn't the case for the Lucifer family… MY family, well mainly because of my father Rizevim Livan Lucifer. He's mad, insane, and evil, his mind twisted when he lost his Devil King Lucifer title to Sirzechs after the great war but that isn't the problem now he's now after my family because I tainted HIS blood by falling in love with a human and having two sons twins that's rare for devils because of how low our fertility rate is why I love them with all my heart so that why sent them to the human world with my serves to keep them away from him.

OH SWEET SON OF MINE WHERE ARE MY GRANDCHILDREN, GRANDPA WANTS TO PLAY WITH THEM?!?!, he screamed madly throughout the familiar forest. Seeing him appearing from the tree line.

Not anywhere for you to know I sneered, you don't deserve that right!

Oh, don't say such things, grandpa only wants to hug and squeeze them until blood sprays out HAHAHAHA.

YOU SICK BASTARD I Roared I won't let you get close to them.

It's fine I already sent Euclid after the one named Valie the other one we still haven't found yet sadly what was the other one's name, pondered aloud putting his index finger to his chin OH ISSEI was it, oh don't worry son you won't be alive long enough to see me have my fun with them to bad they're not old enough to scream out in pain, he said with a horrid smile creeping across his face.

I won't LET YOU I screamed as I charged my aura of annihilation and shot an orb of it at him, but it didn't do anything to him, he just swatted it away.

Oh, my sweet son wants to play catch with his daddy, how about you catch one of mine as he shot an orb of annihilation back at me it was more dense and potent and a lot faster I was barely able to get out of it taking one of my arms with it.

Crying out in pain falling to the ground bleeding profusely, impossible you shouldn't have that much magic power. How did you obtain it? I yelled, catching Rizevim, surprised.

Oh dear, looks like I missed it, I won't miss this time but before that since, you asked all so nicely i'll tell where I obtained more power I received it from ophis-chan he said smiling creepily another orb of annihilation at me and all i could do is lay there unable to move but i had to tell someone close to watch over my son Issei because the three servants I sent with Valie were already strong.

Rizevim was content with destroying what was left of his son, left to find Eucild to see if he caught one of the disgusting spawn little did he know the Razevan was still alive to sucre hope for his sons survival, barely able to make a comution circle to called one of his close friends for help.

After waiting and the moment Razevan heard it connect a familiar voice spoke up. Razevan-sama do you need anything?

Yes Grafiya, come to these coordinates please, Razevan spoke weakly.

Hearing his weak and fading voice, the one now dubbed Grafiya responded quickly and worriedly, I'm coming now!!!

After a moment of silence you could see a beautiful blue silver magic circle right next to Razevan Lucifer or what was left of him.

As Grafiya stepped out of the magic she was horrified to see the upper torso of Razevan Lucifer blood and entrails littered the area before her. screaming she ran over to the man that should be dead RAZVAN-SAMAA WHAT HAPPENED TO YOU, Grafiya screamed.

Ah.. cough Grafiya you're here just in time to i'm running out of time, my father did this and he's after my two sons, my son named Valie, already has three of my servants protecting him but my other son named Issei needs you, your cousin Alistair and his wife Skarla took him to Japan in the human world please help them look after him and also don't tell you sister or her husband Sirzechs until their old enough and strong enough to protect themselves.

After the last word the light in his eyes dimmed and he was gone of this world, with tears in her eyes Grafiya nodded at her last masters last orders no not orders but last wish.

Linebreak 4 years later

Gremory Mansion

Grafiya-nesan yelled, a tiny little redhead girl running down the hall. She had long crimson red hair with blueish green eyes in a small pink dress looking for the silver haired maid.

Rias-sama there's no reason for you to be running and yelling inside. It's not proper, a voice scolded from behind her.

I..i know b..but i'm just excited i can't help it, Rias said meekly turning around to see a silver haired beauty wearing french maid attire with boxsum figure that would put any man in a trance.

Oh I wonder why you're so excited, is it because we're going to visit Issei-Kun for his birthday?'' Grafiya said, smirking already knowing why Rias was so excited.

When hearing Issei Rias's face lit into atomic blush looking down playing with her hair, y..yes Ise-kun i've missed him a lot.

Grafiya looking and issei amused decided to tease Rias one more time because her reactions were priceless, oh yeah Rias-sama did you tell your parents and brother about your declaration you made last time we saw Issei-Kun?

Grafiya-nesan Rias whined, turning even redder.

Tell us what Grafiya? the voice said in amusement. Hearing that voice made Rias jump and the smile on Grafiya's grow wider and assessed their new company with respect.

Lucifer-sama, Germory-sama, lady germory-sama. Grafiya bowed, looking at two men with the trademark shoulder length red hair and blueish green eyes of the Gremory clan and beautiful women with flaxen colored hair and piercing violet eyes.

Hearing their names Rias's blush matched her crimson hair squeaked and ran away.

Oh dear I've never seen my Lil Ria-tan so flustered before, Sirzechs said, earning a giggle from the rest.

Oh Grafiya-san, can you tell us why Ria-tan is so flustered, Venelana asked?

Oh yes lady Gremory, well you see the friend i visit in the human world has boy he's taking care of and his name is Issei and Rias has came with me a few times to visit when meeting him, shes be very fond of him and the last time we were there she declared that she was going to marry Issei-kun when they got older.

All three devils looked taken aback then all three started laughing uncontrollably then after a good moment they caught their breath.

Grayfiya stood there for a moment then sighed to herself and said, Would you three like to accompany me and Rias-sama to Issei-kuns birthday party?

The three devils looked at each other and then nodded sounds like fun we'd love too, sirzech replied.

Ok we have to leave in three and a half hours, Grafiya said and the three devils nodded in agreement.

Linebreak three and a half hours later

Issei's home Kouh, Japan

Issei it's about time for our guests to be here, are you presentable, do you need any help. Issei's father yelled up the stairs checking to see if his son needs help with his suit.

It's fine dad, I got it. I've been practicing all week on how to put it on… i won't lose to a suit, Issei yelled back muttering curses while putting it on it went quiet for a moment then Issei yelled back down the stairs, Hey dad i need help sounding defeated.

Issei's father sighed then ascended the stairs walking into Issei's room smiling, to Alistair Issei was the cutest thing while pouting. Entering Issei's room Alistair was shocked he looked like the spitting image of his father but with brown hair and eyes to match do to seals being placed on him to hide his presence.

D..dad do i have to show my true self to the Gremory family, IsseI asked with a downcast look.

Yes my son, I understand how you feel but think about it, do you want to lie to Rias-chan forever, Alistair questioned. Plus look the Gremory family was really close to you father before he died they at least have the right to know that his sons made it to safety.

Issei gave another downcast look and said i hope I get to see my brother again.

You will buddy just don't give up, Alistair said reassuring him. You also look great my boy

Thanks dad…

KNOCK KNOCK KNOCK

Oh it looks like the guests were here walking out to go answer the door but his wife beat him to it, skarla was already at the door.

WHAT THE!!!!!

SKARLA-CHAN!!!!

When Ailstair reached the door to see that Sirzech and his father were speechless and Skarla was tackled to the ground being hugged to death by Venelana Gremory and Grafiya shaking her head and the little Rias was confused.

HAHAHA i see that you three never change, Ailstair laughing at their dumb struck faces.

Come on in, I'm not trying to heat the outside, Alistair gestured for the three devils to come in.

After Alistair got everyone to calm down and his wife returned to the kitchen to finish cooking dinner, the first one to say anything was Sirzech.

I'm confused. I thought you two were killed by Rizeivm, Sirzech questioned.

That's why I asked Grafiya to bring you it's time you all knew the truth, just don't freak out, the kid is already nervous as it is, and also Rias-chan don't drool this time,Ailstair said with a smirk causing the redhead girl to blush.

ISSEI MICHAEL LUCIFER I'M REMOVING THE SEAL GET YOUR BUTT DOWN HERE IT'S RUDE TO KEEP YOUR GUEST WAITTING, Alistair yelled while snapping his fingers.

Coming boy's voice rang out, as a seven year old boy made his way down the stairs, he wore a silverish blue suit with black outlines his hair was the same color but his eye were something else to see, heterochromic eyes his left is hazle, and his right one being light blue.

His aura.. Was the only thing that came out of Zeoticus's mouth.

Yes, Ailstair said, understanding his friend's shock, Issei's aura screams Elegance, Majesty, power and surprisingly kindness.

Uhh.. Hello my name is Issei Michael Lucifer. It's very nice to meet you, Issei said while revealing his 10 black devil wings and bowing in courtesy

To say that the four devils speechless was an understatement of the century.

Sirzech only said how

Venelana and Zecticus were flabbergasted

The poor little red head drooling again

In the middle of the silence Grafiya coughed and got everyone's attention and started to explain everything to them, Four years ago i was summoned to the familiar forest by Razevan-sama, his voice was labored and weak so i grew worried so i ran to his side as soon as he gave his coordinates. Upon arriving at said coordinates he laid on ground his body completely Mutilated only his upper torso remained with chunks of muscle, bone and entrails scattered around the forest.

Sirzechs flinched when Grafiya explained Razevans' condition when she found him.

Razevan-sama told me about Issei-sama, and that Ailstair and Skarla had taken him in to hiding in the human world, in a country named Japan but that was all he had the strength to say shortly after he was gone, the last thing he told me was not to tell you Sirzechs of his existence because that would give up the cover they had if a devil king was around them, Grafiya finished explaining

Venelana imdely after hearing everything ran over to Issei and wrapped him in a bone crushing hug with Rias following because they were the only ones that noticed tears rolling down his cheeks no sniffing no sound just perfect streams of tears.

Issei sobbed in her arms, this being the first time he truly heard what happened to his father. After 30 minutes of sobbing he began to calm down, everyone had a down cast look on their face.

Grafiya turned to issei with an apologetic look on her face, sorry Ise i didn't…

She was cut off by Issei running into her giving a hug, it's ok Grafiya-chan, father did it to protect me.

Releasing himself from Grafiya, Issei looked up like nothing happened and spoke shyly. uhh-i.. I don't think that my Father would want me to be sad on my birthday.., so let's have fun.

With a flash of red Issei found himself on the floor finding Rias hugging him with a death grip not letting go. Rias-chan, what's wrong, Issei asked surprised?

Looking at the scene, Venelana with Mischievous smirk asked, oh Rias dear, you didn't tell us what you declared earlier. Prompting the red her to blush and buried her face into Issei's chest.

Causing all of the adults to laugh.

Making the most out of the situation Rias's Father joined in on the fun of teasing by his daughter. that's right you haven't told us yet, Zeoticus asked with an amused look on his face.

After hearing that Rias squeaked, turning around to see her mom in a fit of giggles, her dad looked at her intently, then turned her eyes and bright red face to her brother.

Sirzech looked back at his sister with a devilish grin that said, my turn. So Ria-tan, are you gonna tell us or not? he asked with an amused look on his face.

After the reveal of Rias's pet name, even Issei was giggling, barely able to speak. Rias stood up and started to speak, uhh… i.. I WANT TO MARRY ISSEI-KUN WHEN WE GET OLDER!!!!!

Prompting Issei to blush while standing up, waking to Rias that was hiding her face with hands, grabbing her hands and softly stroking the back of her hands with his thumbs while looking into her eyes and spoke, Rias-chan I would love that i'll do anything for you, with those few words, Rias melted into Issei's arms.

The adults had a mix of emotions concerned with happiness and Hope.

The first to speak was Venelana, umm there might be a problem with that. Looking at her husband with her eyes but that's all he needs.

Everyone I have something to say and this may prove trouble sum, Zecticus said getting everyone's attention.

Oh. So I must ask, are the rumors true, Alistair questioned?

Yes, Sirzech replied while nodding his head.

Sorry, Issei Rias-chan's off the market, Alistair said with a hint of sadness in his voice.

Hey now let's not get hasty, Venelana interjected.

Surprising both Sirzech and Zecticus, giving her a look of amazement.

Oh. Don't look at me like that you both know damn well I hate the Phenex family and how the men of that family treat women, Venelana stated like it was fact.

Umm.. Mom what are you guys talking about, Rias questioned more than a little confused.

For the long moment Venelana looked conflicted, but by getting a node from her husband she took a deep breath then said, Rias dear you're already engaged to the third son of the Phenex family.

EW WHY HIM, Rias yelled trying not to gag.

It was the devil Council that decided this and didn't care what we thought about it, Zecticus responded.

I don't care what those old bags think or say, Rias Stated while clinging onto Issei possessively.

Well there might be a chance to get Ria-tan out of the engagement but we're gonna need Issei to help with that, Sirzech said, Stealing everyone's eyes.

What are you suggesting Sirzech, Ailstair asked suspicious of crimson devil

No worries my friend, it's just a simple request of Issei if he wants to any way, Sirzech said with utmost sincerity.

Before Alistair could make a response, Issei made his voice known. I'll do it if I can help Rias-chan plus if I get her out of the engagement then I can have her all to myself.

Hahaha there you go Sirzech you got your answer, Alistair said unable to breath

Sirzech was about to say something to ensure that his parents don't kill the only way for Rias to get out of the engagement, but a miracle had taken place. Both Venelana and Zecticus were smiling the biggest grins he's ever seen, now scared for the smiles they had.

Ahh.. you two seem happy, Sirzech asked his parents, afraid of the answers.

It's nothing son.. I'm just happy to see that the boy that declares he'll take my daughter for himself had the eyes of someone that will follow through with it and dares anyone to test the fact, Zecticus said reassuring his son.

Yes yes I agree with your father he's a boy worth trusting plus he's so adorable the little pout he had when Ail-san said that Ria-tan was no longer available for him to claim, Venelana said in agreement.

Hahaha I'm curious on how you two are gonna go about this? The engagement is with the phenex clan, the only way to break an engagement…Ailstair was amused until he remembered.

With a straight face Alistair voiced his opinion, Nope not happening he will not fight a duel for her hand in marriage, I can't let the supernatural world find out about his existence. It's my duty to keep him safe.

This outburst surprised everyone in attendance, Sirzech, Zecticus and Venelana were at a loss for words. Though it's understandable considering the Alistair they knew was layed back and carefree to a fault.

Issei was as surprised he's never seen his adopted dad so angry but before his dad could burn this bridge Issei spoke out to the group, Its fine, if I have to I will fight for Rias-chan but also I can't hide away forever I understand that father wanted me to have a safe life but I WILL NOT COWARE FROM THE WORLD. With the words of conviction being spoken the aura of the boy condescended into his wings giving off pitch black aura that made the air hard for everyone to breathe.

ISSEI calm down Rias-chan can't…Alistair yelled, noticing something fascinating.

Being shocked out of his little rant, Issei rained in his aura and looked at Rias she was completely fine maybe more than that, Rias was cuddled up to Issei's chest all nice and comfortable but the rest were all pale like they saw something that could end them all if it wanted to.

Sorry I got carried away, Issei apologized to the older devils in the room

Feeling a hand on his head a new face made her presence known, my my it looks like my son forgot his manners.

At this moment Issei knew he fucked up, slowly turning his head his face paled, h-hey mom.. how's it going.

Ooh.. someone has a sense of humor today, okay mr. humorous you're coming with me, Skarla demanded while dragging Issei off into another room.

Alistair ignores his son's cries for help and forgiveness then shivers, then turns his attention to the three older devils that are in the room then to the young red head then spoke, hey Rias-Chan can you go help aunt Skarla with prep-ing the dining table?

Yes of course I'll help, Rias said while getting up to help in the dining room.

When Rias was out of the room Alistair's face straightened, then spoke, There's something about Issei you guys should know.. but first I should ask Sirzech, do you know the real history of the devils?

What do you mean Sirzech wondered cupping his chin then his eyes widened in Realization, you don't mean that history do you?

Yes, Ailstair replied.

Instantly as of reflex or instinct Sirzech formed a privacy barrier then looked at his mother and father then asked, you two know right?

Zecticus nodded then looked at his wife then found that she was confused and spoke, Venelana dear this can't be spoken of anywhere so keep it in heart, mind and soul.

Venelana widened her eyes knowing this ..IS.. serious. Her husband only uses her name when it's very important, understood dear but what am I not aware of if I must ask?

Well mother this is a touchy subject for most of the older devils, you know that we devils were created by the original Lucifer?

Yes, Venelana nodded.

Well that's half true half false we devils were created by Helel the first ark angel also known as Lucifer the first fallen then first devil but that isn't truth, Helel never because a devil or demon they stayed angel because they were created before the system, Sirzech explained

I still don't understand, then how are the ones from the Lucifer house devils? Venelana asked.

Well long story short Helel created the first generation of devils also known as the prime demons out of their own flesh and blood and giving them their own powers, same can be said about the Lucifer clan, Alistair interjected.

So you're telling me that the original Lucifer wasn't the original Lucifer, Venelana asked ultimately confused
