Morning in the town of kuoh.

At the hyoudou residence in the living room the family sitting on their couches.

Both parents see both sons in their own thoughts about their conversation with azazel last night after their date and what happened in issei's room.

Flashback.

The family looking at azazel who is a little amuse about what happened.

Asia already left since she's part of rias peerage and they don't want her to worry rias at the moment.

Azazel: Wow issei you almost got laid with the gremory heiress, I'm so happy. Said with a smile.

But short lived seeing angelicas glare which made him shut up.

Azazel: Alright geez stop giving me that look angelica can a man have fun teasing. Said with a nervous look.

Angelica: The only one who can tease my boys will be me and only me because I know their in love with the girls and I wanted grand babies to spoil. Said with a smile.

Which once again both bothers groan at this and blushing of embarrassment of their mother saying about grandchildren.

Y/N: Can we please focus on the matter we are discussing about. Said with a embarrassed look and blushing.

His brother agreed with him on that one.

Azazel: Fine judging by your said that rias was about to make her first time seems that it is almost near the time and his patience is getting low. Said with a neutral look.

Which brought their attention about that.

Issei: Who are you talking about?. Said with a questionable look.

Azazel: Well from what I heard a couple years ago from my sources, that the head of the gremory family made a arrange marriage contract with the head of the phenex family before rias and mio were born. Said with a neutral look.

This got their attention about that a marriage been made before the twin sisters were born.

Y/N: Well judging about rias sudden action did last night she doesn't like the guy. Said with a neutral look.

He nod.

Azazel: Oh believe me the man she's engaged to is worse than me and the pervert duo combined. Said with a neutral look.

He can admit that he's a pervert as well but he know when he must stop his actions not wanting the ladies feeling uncomfortable.

This got both twins attention.

Issei: Who is he if you don't mind telling us?. Said with a little serious look.

If what azazel is true he couldn't help but feel bad for rias if this guy is a huge pervert.

Azazel waste no time summoning an image of a blonde haired man with looks like nearly twenty years old wearing a noble clothing with a arrogant smirk on his face.

Azazel: This man is riser phenex and third in line with the house of phenex before his older brother ruval phenex who is the current heir and his older twin sister clair phenex who is next in line, that household has a special ability that they can regenerate any damage inflicted on them. Said with a neutral look.

The family see the image and now they already not like him at all.

Y/N: This guy just wanted rias for her body. Said with a neutral look.

He nod.

Azazel: From what I heard rias disagree to marry him and tried to tell her parents and her brother about this but they already made agreement by the council. Said with a neutral look.

This made both parents mad to hear especially devolos.

Devolos: I have a feeling that those old farts of the elder council agreed to this for the preservation of the pure blood devils. Said with a serious look.

He nod which made them even angrier.

Angelica: Unacceptable how could they do such a thing, I may not like them in the past but this is far worse for their own children against their will. Said with a serious look.

Devolos place a hand on his wife shoulder to calm her down knowing she is mad at this.

Devolos: I know how you feel angelica but we must act cautious on this. Said with a concern look.

She sigh calming down knowing her husband is right.

Then noticed both brothers in their own thoughts about riser.

Y/N: I have a bad feeling that he won't stop to rias isn't it. Said with a neutral look.

He nod.

Azazel: Yeah from what I heard that he wants mio in this saying to preserve a greater bloodline but I heard some word that he setting his eyes on sona sitri. Said with a neutral look.

This got (y/n) eyes glowing blue getting mad hearing that along with issei with his eyes glowing green.

Y/N: If that bastard ever touches sona in a bad way I will rip him to pieces make scream for mercy. Said with a serious look.

Issei: Count me in bro, I won't let that bastard get any with this just because he wanted rias body. Said with a serious look.

Both parents smile seeing them being protective to the girls is because of their dragon side calling out to protect their chosen mates even their devil side wanted them along with their angel side with their pure love to them.

End flashback.

After that chat azazel went on to check somethings in his end about a certain warmonger.

They see both their sons still in their thoughts.

Issei: This is not fair for rias to be an arrange marriage before she and her sister were born. Said with a neutral look.

Y/N: I agree with you bro if what pervy sage number two said is true that man won't hesitate to say about woman's body to the public. Said with a neutral look.

He nod of understanding.

Devolos: Well boys we will think about it later time but now you have school today. Said with a smile.

They look at the time seeing they only have an hour to get there.

Twins: Later. Said in sync with a neutral look.

They left leaving both parents alone to talk.

Angelica: Dear I have a feeling that both of them want to stop this. Said with a small smile.

He smile as well.

Devolos: Lets keep an eye on them and see what it leads if it comes to that. Said with a smile.

Skip.

Both brothers attending class hearing the teachers explanation of the topic but as usual both brothers usual routines.

But while they were listening (y/n) glances at his brother who's looking to the window but towards the occult research building knowing full well why he's looking in that direction.

Y/N 'thought': Worried about rias bro?. Said in his mind with a neutral look.

He glances at his brother for a moment and back out the window.

Issei 'thought': Yeah, can't believe her parents would do such a thing before she was born it's not right. Said in his mind with a neutral look.

Y/N 'thought': I understand how you feel bro but we must be cautious about what actions we must take, I would have feel how you feel if that bastard goes after sona. Said in his mind with a neutral look.

He agreed about that part but couldn't help but feel this way.

Later.

School over and everyone headed home.

Both brothers looking to see asia and the rest of rias and mio's peerage heading to the old school building.

Y/N: Seems that something is going on and I get the feeling that riser is making his appearance soon. Said with a neutral look.

He nod of understanding.

Which is true since now they sense the maid grayfia there and now suddenly they felt a presences of a new devil with fire element in the building meaning his there now and a rise of power between rias and riser just now.

Issei: We're going now and see that guy. Said with a neutral look.

Y/N: Took the words right out of my mouth. Said with a neutral look.

They went in the building straight to the clubroom until.

Rias: FOR THE LAST TIME I SAID NO RISER!!. Yelled through the door.

This made the twins stop in their tracks hearing rias scream meaning she's furious.

Riser: My dear rias you must understand that this is for the future of our pureblooded race, although you and your sister got great peerage members including the blonde hair girl she made be small but make great for bed. Said through the door.

Thats when they heard asia screaming and that made both brothers extremely pissed of.

Within the clubroom.

Rias and her peerage along with mio and her peerage glaring at riser who is holding and groping asia from behind.

Grayfia seeing this getting a bit too far and was about to put a stop to this.

Until they felt a rise of power coming from outside the room which made grayfia confused and surprised at the sudden power.

But rias along with her sister and their peerage nervous knowing who is outside.

Rias: Riser let her go the two people that are looking after her are right outside and they won't show any mercy. Said with a little nervous look.

Only he glare at her.

Riser: As if they can hurt riser, they must be weak after riser shows them the power of a ph-. Before he could finish his sentence.

Suddenly the door busted open and two red and white blurs past through great speed.

Before riser could react his face was met by the boosted gear fist and a kick in the chest missing asia.

Which by the force of the attack let's go of asia and crash to the wall.

They see at the center of the room both hyoudou brothers with their sacred gears out glaring at the down phenex with great anger and their auras flare.

This got grayfia surprise to see both boys possession of longinus sacred gears.

Asia noticed them and quickly hug (y/n) while crying and he use one arm to hug her while glaring at the blonde man.

Y/N: If you ever touch her again like that. Said with a angered look.

Issei: Or any girl in this very room. Said with a angered look.

Their auras flare even more.

Twins: We will rip you apart and make you scream begging for mercy. Said in sync with a angered look.

The girls are quite surprised at their sudden power up now and couldn't help but tremble a bit in fear seeing them act this way.

Grayfia is shocked the most is the presence she felt from them is familiar.

Grayfia 'thought': Impossible they were dead in the great war from the two dragons attack. Said in her mind with a surprise look.

Riser getting back up his pain healed and glare at the two brothers.

Riser: You two have some nerve to strike riser. Said with a serious look.

Both twins glare at him.

Issei: Got a problem with that KFC reject. Said with a serious look.

That got him mad to hear that and was about to say something.

But grayfia suddenly appeared between them.

Grayfia: That is enough my lord gave me direct orders if a fight is about to happen I will stop it. Said with a serious look.

That got riser to stand down knowing full well about sirzechs lucifer peerage are stronger.

But both brothers didn't budge her threat and still continue to glare at riser much of the maid surprise.

Grayfia: My lord and lord lucifer predicted this would happen so the set an alternative. Said with a neutral look.

Which brought rias attention.

Rias: What alternative?. Said with a questionable look.

Grayfia: Lady rias if you disagree about this, then it will be settled by a rating game. Said with a neutral look.

This brought their attention.

Riser just smirk hearing that.

Riser: There's no way they can win, I have most experienced in a match and won. Said with a smirk.

Rias: Why don't they just leave my life put of this. Said with a desperate look.

Grayfia: So you disagree lady rias. Said with a neutral look.

Rias: No, I accept this challenge it is the only way to set me free. Said with a serious look.

Which riser laugh.

Riser: My beloved rias surely you have great numbers so far but riser on the other hand. Said with a smirk.

He snap his fingers and a magic circle appeared bursting in flames revealed fifteen girls.

Riser: Posses all fifteen. Said with a smirk.

This got rias a bit mad but still determined.

Riser: By the looks of it you won't back out then let's make it more interesting then. Said with a smirk.

Which brought their attention and point at mio.

Riser: Riser will allow you two to team up, you win your free but if riser wins I get both of you. Said with a smirk.

This brought great shock to hear and both sisters look at each other and nod.

Twins: We accept. Said in sync with a determined look.

Which he smirk wider and then glare at the two brothers.

Riser: After riser wins the games both of you are next. Said with a serious look.

But to his surprise that both brothers auras flare once more with their sacred gears glowing.

Issei: Better pray to satan that doesn't come to that. Said with a serious look.

Y/N: Because nothing can stop us to put you down. Said with a serious look.

He glare at them but smirk having an idea.

Riser: Really you two think beating riser, since both of you are destined to kill each other someday. Said with a smirk.

But he didn't expect this.

Twins: At least we don't act a spoiled brat with a twenty foot tall stick right in the ass. Said in sync with a serious look.

That got him mad to hear that.

The girls giggle a little at that jab even his own peerage as well even his little sister.

Riser: Rias I'll give you ten days so be ready by then and be ready for the two of you being mine. Said with a serious look.

Then he and his peerage teleport away.

Grayfia: I'll go and inform the family heads of this decision. Said with a neutral look.

Then she teleport away going to inform them and especially inform her master about the twins.

Both brothers looks at rias and mio.

Rias: Thanks you two for helping out getting asia out of that. Said with a smile.

Issei: No worries rias, so need help to train. Said with a small smile.

Y/N: Maybe ask mom and dad to help train as well. Said with a smile.

She smile for a moment thinking they could help but sigh.

Rias: I'm sorry but no. Said with a sad look.

This got them surprised to hear.

Rias: Look I appreciate it but we can't let you two along with your parents get involved in this, leave this to us. Said with a determined look.

Mio: Rias is right we can handle this as long we work together. Said with a smile.

She smile as well.

Rias: Agreed both of you did enough as it is. Said with a smile.

Both brothers seeing that they made their choice.

Issei: Alright then good luck. Said with a smile.

Y/N: Give him hell. Said with a smile.

Then both brothers left leaving the girls alone.

Akeno: Are you sure about this rias?. Said with a concern look.

She nod.

Rias: Yes we must do what we can do with our best. Said with a determined look.

At the underworld.

In a throne room.

Grayfia standing beside the ruler of the underworld sirzechs lucifer formerly gremory, rias and mios older brother.

He's a bit worried and surprised at what his wife is telling him.

The rating game will happen but both his sisters will face riser or be married to him if they lose.

His attention is what his wife reported about the twin brothers possession of the heavenly dragons sacred gear but his most attention is about what she sense in them.

Sirzechs: Are you completely certain grayfia?. Said with a questionable look.

She nod.

Grayfia: Yes my lord there's no mistaken about those two boys, they are related to them or should I say their children. Said with a neutral look.

This brought his own thoughts about it it.

Sirzechs: If it's true then everything will change. Said with a neutral look.

She nod of understanding.

Sirzechs: Well then make the preparations I get the feeling if what you said about what they did to riser, they will come to save them. Said with a neutral look.

She nod.

Grayfia: I'll get started right away. Said with a neutral look.

She left the room leaving him alone in his thoughts about what his wife said.

Sirzechs 'thought': If grayfia says about them is true then they must be alive, the one devil that should take the throne to rule our faction but if he's married to an angel wife this will be different. I wonder how the whole three great factions react about them. Said in his mind with a small smile.

End chapter.

A/N: I hope you all enjoyed this chapter and please vote if you like it.

P.S: I will skip the training and rating game parts since both brothers didn't take part of it and start the showdown against riser and trust me you readers will like it.

Peace out readers.
