When everyone entered the room they saw Rias and Soren standing next to each other while Grayfia was standing not too far from them, and Rias saw Sona put together what had happened, she secretly used magic to clean up the room. Soren then took his place back on the couch and Rias took her place back at her desk while Grayfia stood next to her, then everyone else took their seat on the opposite couch from Soren and began looking towards him in curiosity.
[Buchou… Why is Soren here, and what was that big presence we sensed?... Even Ddraig felt suffocated]: issei
Soren didn't say anything and neither did Rias, they just looked towards each other for a split second while Grayfia was about to speak, but in the next second another Magic circle had appeared in the room, and out from it came a Blonde haired man appearing to be in his early 20's with Blue eyes wearing a Burgundy blazer with Gold embroidery on the right with matching pants and Black dress shoes. Underneath the open blazer the man wore a White dress shirt that was not full buttoned showing off his a bit of his chest, and when he appeared he left scorch marks on the floor due to the flashy fire show that came along with his entrance. Soren didn't like how the guy presented himself, and he especially didn't like how the man made his entrance, Soren just felt that that entrance just shouted "Come fight me, and you will get burned" But even though the man gave off that arrogant aura, Soren felt that he was just a bug waiting to be squashed under his feet.
[Rias my soon to be wife… I've come here to inform you of great news]: riser
[What do you want Riser, have you come to tell me you no longer want to marry me? If so, it appears I have someone had seen my suffering and helped me out]: rias
[Not even close!... I have come to tell you that the wedding has been moved up and will be next week]: riser
[What!?... But I was supposed to finish off this school year before being forced to wed… How could this happen!]: rias
[Haha, why try and prolong it?... It's bound to happen, so why wait… Don't worry, after the wedding I will make sure to take super good care of both you and your peerage, but the men will need to fend for themselves]: riser
Riser then moved to sit on the couch across from Rias peerage where Soren was, and as he sat down Soren spoke up shocking Riser.
[Have I told you that you can sit there?]: soren
[W-what!?... When did you get here?... Rias, is this some new member? Why do you need so many male members?]: riser
Before Rias could respond to Riser's rude attitude Soren had spoken up taking hold of Riser's attention once again.
[Don't ignore me Flaming Pigeon… Now, who told you that you could sit next to me?]: soren
Riser then got furious as he had never been called names as such, and he would be damned if he were to let some weak trash that he couldn't even sense anything from be the first to disrespect him.
[You have no power so you must still be Human so I'll make this easier for you… Apologize and remove yourself from the couch as I have taken claim of it, and I will kill you painlessly… Don't do as I said and I will torture you until you die]: riser
Just as Riser said this, Soren decided to push riser over his limits with his next words.
[Oh?... So lenient for someone who has just finished fucking your soon to be wife right here in this very room… *Deep Sniff* Ahh, you can still smell the sex in the air… And she was quite tight as well]: soren
As Soren spoke Riser's face began to contort to the blatant lies that Soren was spouting, but as he looked over to see Rias' face becoming increasingly more Red to the point her face matched her hair Riser shot off the couch as flames began to surround his body, and he grabbed Soren by his collar and began to shout.
[You dare to take what rightfully belongs to me!?... I won't just kill you now, I will torture you for the rest of your Human life, but that won't be all, I will torture your entire family as you watch, and to teach you for taking what isn't yours I will take away that little peanut you would call a dick and make you eat it!]: riser
[Wow… That's kinda gay]: soren
As Soren said that, some of Rias' peerage members began to chuckle a bit before hiding it behind their hands, but this didn't go past Riser unnoticed.
[It's not gay! It's torture!]: riser
[I don't know man… Seems kinda gay to me]: soren
Riser's face began to contort due to rage while Soren noticed Issei looking over at the both of them while licking his lips a bit.
'Wait a minute… Is he licking his lips towards us?... No, it must be because his lips are dry, that's all… Issei was known to be a super pervert into boobs': soren
As Soren was thinking this he noticed Kiba had his hands wrapped around Issei's neck as he also began to like his lips.
'No… What's going on here!?... Kiba seemed gay in the Anime, but he was defenitly into women… What is this parallel world?': soren
Just as Soren thought this, he noticed Riser had began to become infuriated due to Soren not paying attention to him and then threw a punch covered in flames towards Soren's face, but Soren just let his Ki flare out from his body and the punch lost any bit of strength it held due to colliding with Soren's Ki.
[W-what did you just do!?... Why are you not being burned into cinders!]: riser
[Well it's simple my dear Watson… You are just a bug waiting to be crushed into nothingness]: soren
[Bug?... I'll show you who the bug is, I'll kill you for touching my Rias!]: riser
Soren had about enough of Riser's antics and decided it was time for him to die, and if he was going to be hunted down by the Phenex family because of it, he would just add another family to the "To be Slaughtered" list. Soren then disappeared from the couch and watched as Riser hit his after image with a smile, but after realizing that he had hit nothing, turned to see where Soren went, but as he turned around Riser saw a fist about to impact with his face, and then he saw Black. Soren had used a full power attack and blew Riser's head off with a single attack, but due to Riser still having magic power left, it began to reform in a ball of flames, and when Riser reappeared he had a bit of sweat run down his forehead, but then decided to try and scare Soren.
[Hahaha!... You can't kill me, I'm an Immortal]: riser
[Oh?... You may be Immortal, but you can still die… Lucky for you, I know a few ways to kill an Immortal, as well as a God]: soren
When Riser heard Soren's words he thought he was bluffing, but in the next second he began to sweat at Soren's next words.
[1 Death down, Unknown amount left to go… I'll keep killing you until you stay dead… Hahahaha!]: soren
Soren then punched out once again and killed Riser once again, and just like last time, Riser began to reform only to be killed once again. Soren continued to one shot Riser for a few more times before Soren noticed that Riser's BP was getting lower and lower meaning he was losing magic every time he died, and Soren thought that just a few more would get rid of him for good, but right before Soren punched out Riser shouted.
[W-Wait!!!... Please! Stop!... I can't take another hit, I promise I will give up on taking Rias as my wife!... Just, don't kill me again]: riser
Soren held Riser by his collar the same way Riser had held Soren by his collar, and while holding his hand in a cocked pack position Soren began to think about Riser's words while Riser himself was looking away from Soren while shaking like a little puppy left out in the cold. Soren then slowly lowered his fist and when Riser saw this he had hope, but then Soren just threw him against the wall and made a big crack as Riser had passed out due to the power used to throw him, and all Soren could do was thank Rias that the wall was reinforce or the school might have seen a real Flaming Pigeon fly.
[So, now that that's taken care of I guess I'll introduce myself… My name is Soren, and yes, Rias is going to be my wife, but she won't be my only wife… Now let me ask you Rias, are you okay with this fact?]: soren
Rias had looked a bit disappointed that Soren had outright decided that she wouldn't be his only wife, but deep inside Rias didn't mind that Soren would have more wives as long as he still pays attention to her as much as the other girls.
[I'm okay with this, but you must promise to love me just as much as everyone else in the future]: rias
Soren then gave a smile hearing Rias agree with his future plans to have a harem, but he knew that promising something as such would be hard, but he would do his best, and if it gets to the point he can't keep up he would stop increasing.
[I wouldn't have it any other way Rias… Now when shall we have out wedding?]: soren
[Hmm… How about using the already planned wedding date, and since Riser will no longer be attending, you can take his place]: rias
[Haha!... I like how you think, but you do know this will piss off the rest of the Phenex House right?]: soren
[I'm ready to go against the world is it's with you]: rias
Just as rias said that, all the participants in the room began to release "Aww" sounds from their mouths while secretly congratulating the both of them, but Grayfia was not having it as she began to reprimand Soren for his actions.
[How dare a Human try and start problems between Noble Houses!... You do know that this could start a potential war between the Devils if this marriage doesn't happen… Are you perhaps trying to start a war?]: grayfia
[War? No… I'm just taking what's mine… Don't you know what it's like to form your own love interest and want to pursue it with all your heart?... Rias simply didn't want to marry Riser, but wants to be with me, so I took an old fashioned approach and fought for her hand, and I won]: soren
[Fine, you want to be qualified to marry Rias, then come and make yourself known in front of both the Gremory House Leader and the Phenex House Leader, if you can convince them that you are indeed worthy, then you will be allow to marry Rias next week]: grayfia
[Fine!... Take us to the Underworld then]: soren
Soren was now not only going to get Rias, but also achieve his goal of getting to the Underworld to take the next step in clearing out the Devil family that dared to send one of their children to the Human world to capture Rin. Grayfia just sighed and had everyone gather around her while Issei picked up Riser with a devious look on his face, and after everyone was there, the magic circle appeared and everyone was teleported out of the ORC and into the Gremory territory. Grayfia then went to inform the Gremory House about what happened and left Rias to show everyone around her home, and as Soren was following Rias, he noticed both Kiba and Issei ran off somewhere with Riser, and some say that you could hear ghastly screams of a man losing his pride, but nobody dared to go and risk their own pride.
[So Soren… How big are you down there?]: akeno
When Rias heard her Queen's words she quickly turned around and snapped at her.
[Akeno!... Don't ask him such a thing, don't you know he is mine?]: rias
[Ara ara… He did say that he will have multiple wives, so why can't I be one of them?]: akeno
Rias just blushed as she noticed that she began to be too possessive with Soren, and Soren could decide on who he wants to form relationships with, but she still wanted to have some kind of say in who joins as not just any girl can just join.
[Akeno, how about we get to know each other before asking such personal questions… And if you want to be with me that's fine, but talk with Rias about it, I don't want her to feel left out of any decision about who I take]: soren
Akeno just smiled as she licked her lips a bit and decided that she would have an in depth talk about this situation with Rias later, and just like that the legend states in the Underworld that if you hear the screaming of a man losing his pride, you will witness the sky shoot retribution lightning from the sky down on one's most hated enemy. The next day, Soren was brought before both Lord Gremory and Lady Gremory, and after a few minutes, both Lord and Lady Phenex had entered the room and took notice of Soren, and while Lord Phenex was feeling anger, he decided to hold it in to hear what this Human brat has to say, and with that Lord Gremory spoke.
[So, you are the one known as Soren… So what do you plan to give my daughter in the future when you marry? Money? Status?]: lord gremory
