Yapping time again! so read in your discretion.

Inside the viewing room.
After arriving in the viewing room, Rias and Akeno were greeted by Trio of Kiba, Gasper, and Koneko first and congratulated Rias for being free of the arranged marriage that her father arranged. They praise Rias a bit and ask about that attack she did against Riser which she answers easily.
"Thank you for helping me too my lovely peerage and I won't be able to do this without you girls and guys," Rias said with a smile while looking at them one by one. Now that the game is over she is able to earn her freedom.
"I know what you're thinking Rias" Sirzches said as he read Rias like a book. He walked towards with a smile her while Grayfia followed behind him, "Even if you are free you'll have the responsibility to the Devil-kind in the future" He explained with a warm smile on his face. Grayfia narrowed her eyes as she stared at her husband suspiciously.
"Huh. Devil-kind? don't you mean the Gremory House then no problem but that's still in the future as Father is still the head of the House" Rias reiterated while putting her hand on her hip. She does not need to take the seat of the Head of the Gremory yet as her father will not retire soon because the devil a long-lived race. Her Father is still quite young in terms of devil years so he can still continue to lead the house for as long he can.
As a matter of fact, Rias' future son/daughter with Oreki can probably be the head of the house instead of her inheriting the seat. Then she can just relax and do whatever she wants while Oreki is with her. "Sorry future son/daughter you're going to take my place so I can be with your Daddy all the time," She thought selfishly while smiling inwardly at her foolproof plan to raise her son/daughter as a responsible adult to replace her as heir.
Unless something terrible happens to her Father that will make him unable to continue being the Head of the Gremory during her vacation and lazing mode then her foolproof plan to raise her kid like that will get affected or derail as she'll be forced to take her father's place as the head of the house. However, she just smiled as she thought that those terrible things to come would not happen because as the anime watchers called it she had a walking plot armor which just so happens to her boyfriend/future husband.
Why is that? because in Rias' eyes, Oreki is overpowered and she thinks can do everything he can do but maybe she is just being biased as he had given or upgraded her abilities to the extent she that she can compete with Serafall who is only slightly weaker than her brother.
However, that is what Rias only estimates as Oreki refuses to tell her about her limit if she trained hard and that is a big IF because she is proud of a sinner of sloth and maybe a bit of lust as she lusts over the word lazy and she also lusts over Oreki want to breed with him so she does her foolproof plan as soon as possible.
After Rias mused for a bit, She frowned as she did not see Oreki in the room even after looking around the vicinity.
"Where's Oreki?" Rias asked with curiosity to the group as she only noticed that Oreki was missing because he did not greet her. After all the musing of making a foolproof plan to be with Oreki without interruption, the man himself was not here. Did he even watch how casually she disintegrates Riser?
"Oreki-san said that he is going to KFP to reserve a table for us" Kiba explained while wondering why Oreki needed to reserve a place for them in those places if they can just take out. "That place must be but something important," He thought while nodding sagely but he was just thinking unnecessary again.
"Fried chicken is good" Koneko added in a flat tone but she was happy to be able to eat those godly fried food again that Oreki bought for her in there.
"Did you eat all of the chicken already?" Gasper questioned as he thought that might be the reason why Oreki wanted to buy or eat in the KFP.
"Sorry, I can't help it because it was really good and yummy!" Koneko explained while scratching her cheek embarrassingly.
"Then if it's really that good as Koneko said then that restaurant that Oreki wanted to reserve must be full of people" Akeno concluded based on Koneko's reaction while nodding sagely.
"Meh, it was not that full as it's a new thing for now" a voice sounded making the devils turn their heads to the source of the voice and there he was, Oreki with a smile on his face.
"Oreki! Where have you been!?" Rias shouted while doing a typical tsundere pose with her arms crossed.
Oreki frowned while staring at Rias' before turning his head to her peerage members giving them a questioning look but they just shrugged, not understanding why the hell Rias was asking that question as she already knew what Oreki had gone through after talking about it just now.
Seeing this, Rias laughed lightly before saying "Sorry, sorry, I just want to pretend like a needy girlfriend" She said with a smile while moving her hand left and right.
"You don't really need to pretend because you are already one," Oreki said casually with a smile as he absorbed the mini wrath of destruction from RIas "Anyway let's go and celebrate!" He shouted to them like a child.
Koneko and Gasper excitedly shouted "Oooh!!" while Kiba just shouted a weak "Oohh"
Valerie and Akeno just laugh lightly at Oreki's shenanigans while Rias just sighs lightly before smiling at them. They walk to Oreki to make him easily teleport them to KFP. They don't really need to do that as he can teleport them easily but they did it anyway out of reflex.
However, before Oreki teleported them to the Restaurant, a Sitri magic circle appeared on the floor. All of them looked at it and waited for the visitor to arrive via teleportation as the magic circle glowed brightly before it subsided. After it subsides Sona and Tsubaki are standing there looking around before seeing them.
Sona noticed them staring at their Duo weirdly "Did we interrupt something?" She asked while moving her glasses a bit and Tsubaki also did the same.
"We were about to leave when you girls arrived" Oreki answered and explained with a shrug.
Sona nodded "Then I will make it quick," She said before walking to Rias "Congratulations Rias for breaking off the engagement," She said with a smile while hugging Rias tightly.
"Thank you, Sona, I wouldn't be able to do it without Oreki and my peerages help," Rias said with a smile before breaking off from their hug Sona lightly "Why not come with us and celebrate" She smiled while holding Sona's hands.
Sona stared at Rias for a while before staring at Oreki.
"It's Rias' celebration, so you don't need my permission to come," Oreki said with a confused face.
Sona coughed embarrassingly before staring at Rias "If you want me to come then I will" Sona said.
"How about both of you?" Oreki asked Grayfia and Sirzechs.
Grayfia just shook her head in reply while Sirzechs said that he still had to find people to fix the rating game arena which prompted Rias to apologize again for destroying it.
"Before you leave," Sirzechs said as he stared at Oreki "When do you need the list of wanted Fallen?" He inquired.
Oreki held his chin as he thought inwardly "The Asia thing is going to happen this week so," He then stared at Sirzechs "Preferably this week" He answered casually.
"Then I can make that happen," Sirzech said in confidence "Now go and celebrate," He said.
"Are you sure you don't want to come? the food is really good!" Oreki said emphasizing the food part being good."
"Then give us a takeout," Sirzechs said with a smile and Grafia nodded in agreement with him.
"Okay then," Oreki said with shrugged before looking at around and seeing they were good to go "Then see both of you next week" After he said that he snapped his fingers as they got teleported near the KPF restaurant.
